In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017. Cash used in investing activities totaled $7,852,140 for the year ended December 31, 2016, which included $7,566,142 for the purchaseof debt securities heldtomaturity and $285,998 for acquisition of property and equipment.Cash flows from financing activities10K 1 s109038_10k.htm 10KUNITED STATESSECURITIES AND EXCHANGE COMMISSIONWASHINGTON, D.C. 20549FORM 10K☒ANNUAL REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 FOR THE FISCAL YEAR ENDEDDECEMBER 31, 2017OR☐TRANSITION REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 FOR THE TRANSITION PERIODFROM ____________ TO ____________Commission File Number: 00137714Sensus Healthcare, Inc.(Exact name of registrant as specified in its charter)Delaware271647271(State or other jurisdiction of incorporation or organization)(I.R.S.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida.

We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties.

Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%.

General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

The above table does not reflect prices of the Company’s units, which traded on the Nasdaq Capital Marketunder the symbol “SRTSU” prior to July 26, 2016.(2)Excludes a onetime cash dividend paid to former holders of Sensus Healthcare, LLC units with a preferred return in the aggregate amount of approximately $2.6million that was paid shortly after the closing of our IPO.DividendsWe have not declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%.

General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

The above table does not reflect prices of the Company’s units, which traded on the Nasdaq Capital Marketunder the symbol “SRTSU” prior to July 26, 2016.(2)Excludes a onetime cash dividend paid to former holders of Sensus Healthcare, LLC units with a preferred return in the aggregate amount of approximately $2.6million that was paid shortly after the closing of our IPO.DividendsWe have not declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%.

General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

The above table does not reflect prices of the Company’s units, which traded on the Nasdaq Capital Marketunder the symbol “SRTSU” prior to July 26, 2016.(2)Excludes a onetime cash dividend paid to former holders of Sensus Healthcare, LLC units with a preferred return in the aggregate amount of approximately $2.6million that was paid shortly after the closing of our IPO.DividendsWe have not declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%.

General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

The above table does not reflect prices of the Company’s units, which traded on the Nasdaq Capital Marketunder the symbol “SRTSU” prior to July 26, 2016.(2)Excludes a onetime cash dividend paid to former holders of Sensus Healthcare, LLC units with a preferred return in the aggregate amount of approximately $2.6million that was paid shortly after the closing of our IPO.DividendsWe have not declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%.

General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

The above table does not reflect prices of the Company’s units, which traded on the Nasdaq Capital Marketunder the symbol “SRTSU” prior to July 26, 2016.(2)Excludes a onetime cash dividend paid to former holders of Sensus Healthcare, LLC units with a preferred return in the aggregate amount of approximately $2.6million that was paid shortly after the closing of our IPO.DividendsWe have not declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%.

General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

The above table does not reflect prices of the Company’s units, which traded on the Nasdaq Capital Marketunder the symbol “SRTSU” prior to July 26, 2016.(2)Excludes a onetime cash dividend paid to former holders of Sensus Healthcare, LLC units with a preferred return in the aggregate amount of approximately $2.6million that was paid shortly after the closing of our IPO.DividendsWe have not declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%.

General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

The above table does not reflect prices of the Company’s units, which traded on the Nasdaq Capital Marketunder the symbol “SRTSU” prior to July 26, 2016.(2)Excludes a onetime cash dividend paid to former holders of Sensus Healthcare, LLC units with a preferred return in the aggregate amount of approximately $2.6million that was paid shortly after the closing of our IPO.DividendsWe have not declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business. We assess, in conjunction with our legal counsel, the need to record a liability forlitigation and related contingencies.Item 4.MINE SAFETY DISCLOSURENot applicable.35PART II.Item 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITYSECURITIESCommon Stock Market PricesOur common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 42 stockholders of record as of February 1, 2018.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K. The following information should provide a better understanding of the major factors and trends thataffect our earnings performance and financial condition, and how our performance during 2017 compares with the prior year. Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in ourforwardlooking statements. Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%. The increase in cost was due to a greater number of systems sold during the year ended December 31, 2017 compared to the correspondingperiod in 2016.Gross profit. Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

In June 2010,Sensus Healthcare, LLC, a Florida limited liability company (“Sensus (FL)”), acquired all the assets associated with our primary product, the SRT100, from Topex,Inc. for $1.3 million. Following this acquisition, we relaunched the SRT100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), withthe Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, SensusHealthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and we changed our name to Sensus Healthcare, Inc. As a result of thecorporate conversion, all holders of units of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrants and options topurchase units of Sensus Healthcare, LLC became holders of warrants and options to purchase common stock of Sensus Healthcare, Inc., respectively.The SRT100 is a photon xray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating nonmelanoma skin cancers,including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT100 is especially effective in treating primary lesions thatwould otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner ofthe mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do notrequire the use of anesthetics and eliminates the need for skin grafting. We believe that the SRT100 provides healthcare providers and patients with a safe, virtuallypainless, and substantially nonscarring treatment option for nonmelanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retainnonmelanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–basedtreatments with a process that is less invasive, more timeefficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT100product line.Initial Public OfferingOn June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connectionwith the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of theiroverallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Actpursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016. The registrationstatement registered an aggregate of 2,300,000 units, including 300,000 units to cover the overallotment option. The offering commenced on June 2, 2016 and did notterminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc.acted as joint bookrunning managers for the offering.4Our Products and Services SRT100 We offer the SRT100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on severalkey needs and requirements, including the need for a dedicated and costeffective device for the treatment of skin cancer, keloids, and other skin conditions. TheSRT100 provides the following clinical and functional advantages:▪Easy touch automatic setup procedure, including automatic xray tube warmup procedures;▪Specially designed control console for medical physicists and service technicians which provides integrated safety and backup timer controls, automaticsystem conditioning procedures, calibration, xray output verification and system parameters including last treatment status information;▪Advanced patient record management with integrated enterprise workflow management;▪Compact mobile design with a small 30” x 30” footprint and unique scissor xray tube arm movements providing a large range of motion for patient accessand treatment; and▪High reliability and MTBF (mean time between failures) performance that assure availability for the patients and practitioners and lower the total cost ofownership.SRT100 Vision The SRT100 Vision provides customers with additional options compared to the SRT100 base model. These additional options allow for dedicated treatmentplanning and full treatment progression documentation in a patient’s record. The SRT100 Vision provides the user with a unique superficial radiation therapytailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning,and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patientspecific treatment course to maximizepatient outcomes and workflow efficiency. The SRT100 Vision also offers a comprehensive control console and workflow management that provides full record andtreatment tracing, operatorlevel access and functional control, audiovisual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.Sentinel service program We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT100 and SRT100 Vision systems. The Sentinel serviceprogram covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, highvoltage loop maintenance, filters and system cleaning, and system touchups, should they be required during the preventative maintenance session.We also provide turnkey preand postsale services that include the following:▪Providing a preinstall kit for the contractors to prepare the treatment room;▪Room retrofit and shielding;▪System shipping coordination and installation;▪System commissioning by a medical physicist (through a national physics network);▪System registration with the state and daily workflow documentation preparation;▪Clinical applications training with the customer’s superficial radiation therapy staff; and▪Treating the first scheduled patients with our customers (onsite applications training).Consumables We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons, and eye shields, and disposable applicator tips, which are used totreat various sized lesions and different areas of the body.5Competition The medical device industry is highly competitive, subject to rapid technological change and is significantly affected by new product introductions and marketactivities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who usetraditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our productsare designed to treat. As of December 31, 2017, we had three primary medical device company competitors:▪Xstrahl Medical (headquartered in the United Kingdom and with U.S. headquarters in Georgia)▪Xoft (a subsidiary of iCAD, headquartered in New Hampshire)▪Elekta (headquartered in Georgia)Xstrahl Medical primarily focuses on clinical and research xray therapy devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised ofhigher energy devices located in Europe.Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Both eBx products have limited capabilities as to size of lesionsthat can be treated as well as the energy levels that can be used, and require expensive consumables.Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devotegreater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broadercustomer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longeroperating histories and greater brand recognition than we do. Because of the size of the skin cancer and keloid treatment market and the high growth profile of thesegments in which we compete, other companies may dedicate significant resources to developing competing products. Additionally, we may also face competitionfrom smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors inour markets include:▪improved outcomes for medical conditions;▪acceptance by doctors treating nonmelanoma skin cancer and keloids;▪potential greater acceptance by the patient community;▪potential greater ease of use and reliability;▪product price and qualification for reimbursement;▪technical leadership and superiority;▪effective marketing and distribution; and▪speed to market.We may be unable to compete effectively against our competitors in regard to any one or all of these factors. Our ability to compete effectively will depend on theacceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than productsdeveloped by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that havefeatures or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.Sales and Marketing We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitier sales strategy to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a direct sales force(currently 21 people) in the U.S., as well as international dealers and distributors.Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Sales. Our direct sales force for radiation oncology is led by RichardGolin, our Executive Vice President of Sales, Oncology. We plan to continue selling and marketing our products to both the dermatology and radiation oncologymarkets concurrently.6Dermatology Market Private dermatology practices in the U.S. represent the point of entry for most nonmelanoma skin cancer patients. We believe the SRT100 offers dermatologists acompetitive advantage by allowing them to retain patients for the treatment of nonmelanoma skin cancer, rather than referring them out to specialists for Mohssurgery or other radiation procedures. In addition to nonmelanoma skin cancers, our FDAapproved indications include, among others, keloids, Kaposi’s Sarcoma,Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT100 is currently being used by over 70 U.S.dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat Keloids in China. We are continuing to driveour research and development to expand our indications into new areas of treatment, including psoriasis.Radiation Oncology Market For licensed radiation oncologists in the U.S., we believe the SRT100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providingpatients with effective, noninvasive treatment options for nonmelanoma skin cancer. We are in the process of obtaining FDA clearance for a new device that willtreat other cancers.Other Markets As of December 31, 2017, we also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearanceto treat keloids through superficial radiation therapy, plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for thisbenign tumor. Additionally, we believe that plastic surgeons view the nonmelanoma skin cancer market as a growth opportunity that can supplement their existingservices. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce theformation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurableimpact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/Csection procedures, among others.Global FocusAs of December 31, 2017, we had an installed base of 334 units in 17 countries. Our customer list includes leading cancer centers, dermatology practices, hospitalsand plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.Manufacturing and Supply We currently use a third party located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC(“RbM”) pursuant to which RbM agreed to manufacture our SRT100 products. We pay a fixed price per unit under the terms of this agreement, subject to annualadjustments due to changes in the cost of materials. The initial term of this agreement was three years with successive oneyear renewals thereafter. We continue todo business with RbM, although we or RbM may terminate the agreement upon 90 days’ written notice or upon at least 60 days’ notice prior to the end of eachadditional oneyear renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other qualitystandards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable qualitystandards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believemanufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.We believe this third party manufacturing relationship initially allowed us to work with a supplier that has welldeveloped specific competencies while minimizing ourcapital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are exploring thepossibility of adding other third party manufacturers or bringing certain manufacturing functions inhouse, which could include the acquisition of equipment andother fixed assets or the acquisition or lease of a manufacturing facility.7We have a single preferred supplier for the xray tubes used in our products. We believe our preferred supplier has a superior product; however, we also believe thatthe products of alternate suppliers would be adequate for our products. Although we do not have a contractual relationship with our preferred supplier we do notanticipate any material disruptions to our supply of xray tubes. We believe that adequate supplies of xray tubes are readily accessible from alternate suppliers.Intellectual PropertyWe actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products.We also rely on trademarks to build and maintain the integrity of our brand. We own two issued U.S. patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issuedbetween August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex: ▪U.S. Patent No. 7,372,940: Radiation therapy system with risk mitigation▪U.S. Patent No. 7,263,170: Radiation therapy system featuring rotatable filter assemblyThe following patents were issued to us in 2017:▪Russia Patent No. 26333322: Hybrid UltrasoundGuided Superficial Radiotherapy System and Method▪China Patent No. ZL201380013491.7: Hybrid UltrasoundGuided Superficial Radiotherapy System and MethodA total of 14 patent applications are pending and additional patent applications are in process.As of December 31, 2017, we also owned three U.S. trademark registrations. We currently have other trademark applications that are pending.We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatentedproprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to ourproprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.No patents or trademarks may ever be issued or registered as a result of our pending or future applications for such intellectual property. Even if any such patents ortrademarks are ultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitiveadvantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in thefuture may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.Government RegulationOur business is subject to extensive federal, state, local and foreign laws and regulations including those relating to the protection of the environment, health andsafety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofsubjective interpretations. In addition, these laws and their interpretations are subject to change or new laws may be enacted. Both federal and state governmentalagencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that wehave structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possiblethat governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that aremost relevant to our business. For the years ended December 31, 2017 and 2016, we incurred approximately $866,000 and $697,000, respectively, in expenses relatedto regulatory compliance and quality standards.8U.S. Food and Drug Administration (FDA) Regulation of Medical DevicesThe Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended forhuman use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for theoverall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT100 product line.FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that arenecessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will berequired before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.▪Class I devices present a low risk and are not lifesustaining or lifesupporting. The majority of Class I devices are subject only to “general controls” —e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. Generalcontrols are baseline requirements that apply to all classes of medical devices.▪Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety andeffectiveness. Devices in Class II are subject to both general controls and “special controls” — e.g., special labeling, compliance with industry standards,and postmarket surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification(510(k)) process, in accordance with 21 CFR, Part 807 requirements.▪Class III devices present the highest risk. These devices generally are lifesustaining, lifesupporting, or for a use that is of substantial importance inpreventing impairment of human health, or present a potential unreasonable risk of illness or injury. Class III devices are devices for which general controls,by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety andeffectiveness. Class III devices are subject to general controls and typically require approval of a premarket approval application, or PMA, in accordancewith 21 CFR, Part 814, before marketing.Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributedin the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and DrugAdministration Safety and Innovation Act, or the FDASIA, the availability of a de novo pathway was facilitated for certain low to moderaterisk devices that do notqualify for the 510(k) pathway due to the absence of a predicate device.510(k) pathway As of December 31, 2017, all of our products were subject to the 510(k) requirement or are exempt from the 510(k) requirement. The 510(k) review process compares anew device to an existing legally marketed device. Through the 510(k) process, the FDA determines whether the new medical device is “substantially equivalent” tothe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device:(a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics as the predicate device; (c) has supportinginformation submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device; and (d) does not raise different questionsof safety and effectiveness than the predicate device.9To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantiallyequivalent to a legally marketed predicate device. This data generally includes nonclinical performance testing (e.g., software validation, bench testing electricalsafety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, itcan take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, whichmay significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to beeither (1) substantially equivalent to the predicate device and states that the device can be marketed in the U.S., or (2) not substantially equivalent to the predicatedevice and states that device cannot be marketed in the U.S. Depending upon the reasons that the FDA finds the new device to not be substantially equivalent tothe predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for whichthere is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may requestthe FDA to make a riskbased determination of the new device and to reclassify it as a Class I or Class II device. This process is referred to as the de novo process. Ifthe FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer must submit a PMA prior tocommercialization. We have received FDA 510(k) clearances for our SRT100 and SRT100 Vision.After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a majorchange in its intended use, including significant modifications to any of our products, requires a new 510(k) clearance. The FDA relies on each manufacturer to makeand document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and planto continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on plannedchanges that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k)clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcementactions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.Premarket approval pathwayAs of December 31, 2017, we did not market any devices that were subject to PMA requirements. Unlike the 510(k) pathway, the PMA approval process requires anindependent demonstration of the safety and effectiveness of a device before the device can be commercialized. PMA is the most stringent type of device marketingapplication required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the deviceis safe and effective for its intended use. A PMA application generally includes extensive information about the device including the results of clinical testingconducted with the device and a detailed description of the manufacturing process.After a PMA application is accepted for review, the FDA begins an indepth review of the submitted information. FDA regulations provide 180 days to review thePMA and make a determination; however, the review time is typically longer (e.g., 1 – 3 years). During this review period, the FDA may request additionalinformation or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convenedto review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that thedevice is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensurecompliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurancerequirements for the design and manufacturing of a medical device.Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information isneeded), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A device subject to PMA review cannot be marketed until theFDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose postapproval conditions intended to ensure the continued safety andeffectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinicaldata. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.10Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before beingimplemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’stime for review of a PMA supplement vary depending on the nature of the modification.Clinical trialsClinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. Thisregulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial,submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control thedisposition of the investigational device, submit required reports, etc.Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing,mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial.FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of nonsignificant risk devices (i.e. devices that donot meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor isresponsible for making the initial determination of whether a clinical study is significant risk or nonsignificant risk; however, a reviewing Institutional Review Boardor the FDA may review this decision and disagree with the determination.An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showingthat it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of anInvestigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if,among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.As noted above, the FDA may require a company to collect clinical data on a device in the postmarket setting. The collection of such data may be required as acondition of PMA approval. FDA also has the authority to order, via a letter, a postmarket surveillance study, in accordance with 21 CFR, Part 822, for certaindevices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulationsfor future products. Also, our products are not currently subject to any required postmarket surveillance studies.Pervasive and continuing FDA regulationAfter a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply.These include:▪Establishment registration and device listing requirements, in accordance with 21 CFR, Part 807;▪Quality System Regulation requirements, which govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging,labeling, storage, installation, and servicing of finished devices, in accordance with 21 CFR, Part 820;▪Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and which also prohibit the promotion of products foruncleared or unapproved, i.e., “offlabel,” uses;▪Medical Device Reporting regulation, which requires that manufacturers and importers report to FDA if their device may have caused or contributed to adeath or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur, in accordance with 21CFR, Part 803; and▪Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to FDA recalls (i.e., corrections or removals) ifundertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers andimporters must keep records of recalls that they determine to be not reportable, in accordance with 21 CFR, Part 806.11The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcementaction by FDA, which may include, but is not limited to, the following sanctions:▪Issuance of Form 483 observations during a facilities inspection;▪Untitled letters or warning letters;▪Fines, injunctions and civil penalties;▪Consent Decree, which forces improvements in the quality management system through the use of the federal courts;▪Recall or seizure of our products;▪Operating restrictions, partial suspension or total shutdown of production;▪Refusing our request for 510(k) clearance or premarket approval of new products;▪Withdrawing 510(k) clearance or premarket approvals that are already granted; and▪Criminal prosecution.We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance withapplicable state public health regulations. These inspections may include our suppliers’ facilities.International International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market ourproducts in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required toobtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The EuropeanUnion/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, NewZealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatoryfilings.In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with theserequirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstratecompliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, whichvaries according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an ECDeclaration of Conformity based on a selfassessment of the conformity of its products with the essential requirements of the Medical Devices Directive, aconformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conductconformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devicesbefore issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformitywhich allows us to affix the CE mark to our products.Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical DevicesDirective, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEAMember State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products tothe general public and may impose limitations on our promotional activities with healthcare professionals.We have obtained approval to sell our products in Europe, China, Canada, Israel, Russia and Mexico, and we are currently seeking approval in several othercountries.12Sales and Marketing Commercial Compliance Federal antikickback laws and regulations prohibit, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration,directly or indirectly, in exchange for, or to induce either the referral of an individual, or the purchase, order or recommendation of, any good or service paid for underfederal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these antikickback laws include monetary fines, civiland criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,or knowingly making, or causing to be made, a false statement to get a false claim paid. Offlabel promotion has been pursued as a violation of the federal falseclaims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devicesfor indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such offlabel uses.Additionally, the majority of states in which we market our products have similar antikickback, false claims, antifee splitting and selfreferral laws, which may applyto items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies andhealthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing withinvestigations can be time and resourceconsuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies,the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry,including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we arenot in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain orseize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and canrecommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts andVermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration tophysicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed toprescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and theirfamily members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 peryear (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported inan annual submission. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictionswith different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.13Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or mostother federally funded healthcare programs. The federal AntiKickback Statute prohibits unlawful inducements for the referral of business reimbursable underfederally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursableby Medicare or Medicaid. The AntiKickback Statute is subject to evolving interpretations. For example, the government has enforced the AntiKickback Statute toreach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have antikickback lawswhich establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enactedamendments to the Affordable Care Act, among other things, amend the intent requirement of the federal antikickback and criminal healthcare fraud statutes. Aperson or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that thegovernment may assert that a claim including items or services resulting from a violation of the federal antikickback statute constitutes a false or fraudulent claim forpurposes of the false claims statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and ourofficers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare or Medicaid. In addition to the AntiKickback Statute, the federal physician selfreferral statute, commonly known as the StarkLaw, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicarepatients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any otherparty for services furnished pursuant to a prohibited referral. Many states have their own selfreferral laws as well, which in some cases apply to all third partypayors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state selfreferral laws andregulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third partypayors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid.The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and trebledamages.Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S.government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the FalseClaims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide varietyof Medicare billing practices, and has obtained multimillion and multibillion dollar settlements in addition to individual criminal convictions. Given the significantsize of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ andsuppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.Health Information Privacy The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and ClinicalHealth Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans andhealthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable healthinformation. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards withrespect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect theconfidentiality, integrity and security of protected health information.14We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and securityregulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and securityregulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, wemust comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, withoutpatient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policypurposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties forwrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines andpenalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject tomonetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may besubject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incurdamages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other privatepersonal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possibleenforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessaryto address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations,emerging cybersecurity threats and other factors.Research and DevelopmentResearch and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years endedDecember 31, 2017 and 2016, we incurred research and development expense of approximately $5.5 million and $1.8 million, respectively. Most of the increase in R&Dspending in 2017 was related to the development of a device for intraoperative radiation therapy (IORT) for the treatment of breast and other cancers, for which wefiled a 510(k) application with the U.S. Food and Drug Administration (FDA) in December 2017.Employees As of December 31, 2017, we had 45 employees, all in the U.S. None of our employees are represented by a labor union or covered by a collective bargainingagreement. We consider our relationship with our employees to be good.WebsiteOur filings with the SEC are available free of charge through our website www.sensushealthcare.com. The information on our website is not incorporated byreference into this report.Item 1A.RISK FACTORSAn investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making aninvestment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial,materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. Inassessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10K, including our consolidatedfinancial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10K also contains forwardlookingstatements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10K.These risks and uncertainties include the following:Risks Related to our Business We have a history of net losses. If we do not achieve profitability, our financial condition and the value of our common stock could suffer. We have a history of net losses. Our historical losses from inception through December 31, 2017 totaled approximately $11.5 million. If our revenue grows moreslowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to achieve profitability, our financial condition will suffer andthe value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue toresearch and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products thatreceive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we maybe unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly orannual basis, which would significantly reduce the value of our common stock.15If thirdparty payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used andour revenue will be negatively impacted. In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federaland state levels, including Medicare and Medicaid, private health insurers and other thirdparty payors provide coverage for and establish adequate reimbursementlevels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government andprivate payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do notreceive adequate reimbursement payments for the procedures using our products.Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, orCMS, which administers the Medicare program and works in partnership with state government to administer the Medicaid program. Others may adopt differentcoverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursementpolicies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or localcoverage decision denying coverage for any of the procedures performed with our products could result in private and other thirdparty payors also denyingcoverage. Medicare (part B) and a number of private insurers in the U.S. currently cover and pay for both nonmelanoma skin cancer and keloid treatments using theSRT100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage orreimbursement decisions by government programs or private payors, could have a material adverse effect on our business.Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtainedon a countrybycountry basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country.Further, many international markets have governmentmanaged healthcare systems that control reimbursement for new devices and procedures. In most marketsthere are private insurance systems as well as governmentmanaged systems. Our products may not be considered costeffective by international thirdparty payorsor governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, thirdparty payors’ reimbursement policies mayadversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either theU.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.Substantially all of our revenue is generated from the sale of our SRT100 and related products, and any decline in the sales of these products or failure to gainmarket acceptance of these products will negatively impact our business, financial condition and results of operations. We have focused heavily on the development and commercialization of a limited number of products for the treatment of nonmelanoma skin cancer and other skinconditions with superficial radiotherapy. From our inception in 2010 through December 31, 2017, substantially all of our revenue has been derived from sales of ourSRT100 product line and related services and ancillary products. Although we intend to introduce new products, we expect substantially all of our 2018 revenue tobe derived from or related to sales of our SRT100 product line. If we are unable to achieve and maintain significantly greater market acceptance of superficialradiotherapy for treatment of nonmelanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severelyconstrained in our ability to fund our operations. In addition, if we are unable to market our SRT100 product line and ancillary products as a result of a qualityproblem, shortage of components required for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseennegative effects related to the SRT100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition andresults of operations will be adversely affected.16We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectivelycommercialize our products and increase revenues. The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques andprocess controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactoryproduction yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problemsinclude difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictlyenforced federal, state and foreign regulations.In July 2010, we entered into a manufacturing agreement with an unrelated third party for the manufacturing and production of the SRT100 in accordance with ourspecifications. We continue to do business with the manufacturer pursuant to this agreement, although we or the manufacturer may terminate the agreement upon90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional oneyear renewal period. As discussed elsewhere in this Annual Report onForm 10K, we are exploring the possibility of adding another contract manufacturer or bringing certain manufacturing capabilities inhouse. However, if eventuallyimplemented, our plan to bring the manufacturing function inhouse may not be successful and we may be unable to maintain a relationship with our currentmanufacturer or establish a relationship with another manufacturer on favorable terms, if at all.Consequently, we may be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficientworldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products orincrease revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.We have a single preferred supplier for the xray tubes used in our products and the loss of this preferred supplier could adversely affect us.We have a single preferred supplier for the xray tubes used in our products. Although other suppliers exist in the market, we believe that our prefer supplier’s xraytubes are of a superior quality. The loss of this preferred supplier, or their inability to supply us or our third party manufacturer with adequate xray tubes couldhinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure xray tubes from another supplierin the market, which could adversely affect our ability to commercialize our products and increase our revenues.We may be unable to retain and develop our U.S. sales force and nonU.S. distributors, which would adversely affect our ability to meet our revenue targets andother goals. As we launch products, increase current sales efforts and expand into new geographic areas, we will need to retain, grow and develop our direct sales personnel,distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthybecause it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion oftraining, sales representatives typically require lead time in the field to develop or expand their network of accounts and achieve the productivity levels we expectthem to reach in any individual territory. If we are unable to attract, motivate, develop, and retain a sufficient number of qualified sales personnel, or if the salesrepresentatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that aresufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and timeconsuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expectthem to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force anddistributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence theproducts that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate theirrelationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meetour revenue targets and other goals.17The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be acceptedby hospitals, physicians or patients, and may not become commercially successful. Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly inlight of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of thesignificant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. Whilewe believe that our products are an efficient and less invasive alternative to other treatments of nonmelanoma skin cancer and other skin conditions, physicianswho are accustomed to using other modalities to treat patients with either nonmelanoma skin cancer, keloids or other skin conditions may be reluctant to adoptbroad use of our superficial radiotherapy products.We must grow markets for our products through physician education and awareness programs. Publication in peerreviewed medical journals of results from studiesusing our products will be an important consideration in their adoption by physicians and in reimbursement decisions of thirdparty payors. The process ofpublication in leading medical journals is subject to a peerreview process. Peer reviewers may not consider the results of studies of our products and any futureproducts sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption ofour products.Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by ourmarketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians andhospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our salesactivities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products thatare more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted. The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of nonmelanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in theEuropean market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT100 and relatedproducts currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintainthis competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain ourcompetitive advantages over these competitors.Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternativefunctionalities. These companies may enjoy several advantages relative to us, including:▪greater financial and human resources for product development, sales and marketing;▪greater name recognition;▪longestablished relationships with physicians and hospitals;▪the ability to offer rebates or bundle multiple product offerings to offer greater discounts or incentives;▪more established distribution channels and sales and marketing capabilities; and▪greater experience in and resources for conducting research and development, clinical studies, manufacturing, preparing regulatory submissions, obtainingregulatory clearance or approval for products and marketing cleared products.18Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including muchlarger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvalsfor competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology orproducts obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in thesecountries could have a significant impact on our business and operating results. Substantially all of our 2017 and 2016 sales were made to customers located in the U.S. and China. For the years ended December 31, 2017 and 2016, approximately2% and 10%, respectively, of our product sales were to Chinese customers, with substantially the remainder of our sales to customers in the U.S. Additionally, asingle customer in the U.S. accounted for approximately 59% and 20% of revenues for the years ended December 31, 2017 and 2016. Because of our geographic andcustomer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reductionof business with, or less favorable terms within, these countries. A reduction or delay in orders for our products from these countries could materially harm ourbusiness and results of operations.Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will beaccepted by the market in a timely manner, and if we do not do so, our results of operations will suffer. It is important to our business that we continue to build a pipeline of product offerings for the treatment of nonmelanoma skin cancer and other skin conditions toremain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable tosuccessfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, ornew products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:▪identify and anticipate physician and patient needs properly;▪develop and introduce new products or product enhancements in a timely manner;▪avoid infringing the intellectual property rights of third parties;▪demonstrate the safety and efficacy of new products with data;▪obtain the necessary regulatory approvals for new products or product enhancements;▪comply fully with U.S. Food and Drug Administration and applicable foreign government agencies’ regulations on marketing of new devices or modifiedproducts;▪provide adequate training to potential users of our products; and▪receive coverage and adequate reimbursement for procedures performed with our products.If we do not develop new products or product enhancements in time to meet market demand, if there is insufficient demand for these products or enhancements, or ifcompetitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off thevalue or accelerate the depreciation of these assets, each which would materially and adversely impact our results of operations. We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also creates a risk that our products willbecome obsolete prior to the end of their anticipated useful lives. If we introduce new products or nextgeneration products prior to the end of the useful life of aprior generation, we may be required to dispose of existing inventory, or write off the value of these assets, each of which would materially and adversely impact ourresults of operations.19Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems, and if one or morecompetitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected. Our success is dependent in large part on our being an early reentrant into the market for our proprietary superficial radiotherapy systems. If one or morecompetitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability tocompete may be severely impaired.Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition. The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. andforeign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penaltiesfor noncompliance. Other laws and regulations that can significantly impact us include various antibribery laws, including the U.S. Foreign Corrupt Practices Act,and antiboycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways thatinclude, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply withapplicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact ourresults of operations and financial condition.Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, withoutlimitation:▪difficulties in enforcing or defending intellectual property rights;▪pricing pressure that we may experience internationally;▪a shortage of highquality sales people and distributors;▪thirdparty reimbursement policies that may require some of the patients who are treated with our products to directly absorb medical costs or that maynecessitate the reduction of the selling prices of our products;▪disadvantage to competition with established business and customer relationships;▪the imposition of additional U.S. and foreign governmental controls or regulations;▪economic instability;▪changes in duties and tariffs, license obligations and other nontariff barriers to trade;▪the imposition of restrictions on the activities of foreign agents, representatives and distributors;▪potentially adverse tax consequences;▪laws and business practices favoring local companies;▪difficulties in maintaining consistency with our internal guidelines;▪the imposition of costly and lengthy new export licensing requirements;▪the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibitcontinued business with the sanctioned country, company, person or entity; and▪the imposition of new trade restrictions.If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.20Our U.S. business could be adversely affected by changes in international trade regulation.Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certaincountries such as China and Mexico or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond inkind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation ofprotectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability tosell our products in foreign markets. In addition, the Trump Administration has appointed and employed many new public officials into positions of authority in theU.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certainhealthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability tomarket and sell our products in the U.S. and internationally.Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities. Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:▪physician and hospital acceptance of our products;▪the timing, expense and results of research and development activities, and obtaining future regulatory approvals;▪fluctuations in expenses associated with expanding operations;▪the introduction of new products and technologies by competitors;▪sales representatives’ productivity;▪supplier, manufacturing or quality problems with products;▪the timing of stocking orders from distributors;▪changes in our pricing policies or in the pricing policies of competitors or suppliers; and▪changes in thirdparty payors’ reimbursement policies.Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceedanalyst expectations could cause a decrease in the trading price of our securities.We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position. Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualifiedmanagement and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business andrelated industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover ofmanagement personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spendsignificant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies withwhich we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverseopportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we mayoffer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our businessstrategy and achieving our business objectives.Product liability claims could damage our reputation and adversely affect our business. The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposurewe may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injuryand an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time andmoney in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.21We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not besufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increaseinsurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harmour financial condition or results of operations.We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all. Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business.We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT100 and other products, andrelated technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all ofthe activities that we believe would be beneficial for our future growth.We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances onour assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support ourcommercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our businessmay be negatively impacted. As a result, we may be unable to compete effectively.Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:▪the results of commercialization efforts for products;▪the need for additional capital to fund development programs;▪the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;▪the establishment of highvolume manufacturing and increased sales, marketing and distribution capabilities; and▪success in entering into collaborative relationships with other parties.We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meetour goals.To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interest will be diluted. Moreover, theterms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, mayinvolve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures ordeclaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquishvaluable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability todeclare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business,financial condition and results of operations.Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise inaccordance with our business plan. On March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1.5 million and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, as definedin the agreement.22Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is due monthly, and theoutstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness, restrictsthe sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certainactivities. For example, we may not, without the prior written consent of the lender:▪Sell or otherwise transfer all or any part of our business or property, except for transfers in the ordinary course of business or as otherwise permitted by thefacility agreement;▪Change the nature of our business, liquidate or dissolve, undergo a change in management;▪Add any new offices or business locations, including warehouses;▪Change our jurisdiction of organization, our organizational structure or type, our legal name or any organizational number assigned to us;▪Merge or consolidate with any other person or entity or acquire all or substantially all of the capital stock or property of another person or entity;▪Create, incur or be liable for any indebtedness other than as permitted by the facility agreement;▪Create, incur, or suffer any lien on any of our property (including receivables) other than as permitted by the facility agreement;▪Maintain any operating or deposit or security accounts other than with the lender or any of its affiliates;▪Pay any dividends or make any distribution or payment or redeem, retire or purchase any capital stock, except that we may pay dividends solely in commonstock; or▪Directly or indirectly make any investment, including, without limitation, by the formation of any subsidiary, other than as permitted by the facilityagreement.In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operationseffectively and in accordance with our business plan could be materially and adversely affected.If we fail to properly manage our anticipated growth, our business could suffer. Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and otherresources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S.will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue toimprove our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable tomanage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us tomanage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increaseproduction output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the futureexperience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problemscould result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.23Costcontainment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales andprofitability. In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated deliverynetworks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors andoffer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically awardcontracts on a categorybycategory basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of drivingdown pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizations and integrated delivery networkscontracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks.Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of thatgroup purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders.Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members ofthe group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizationsand integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groupsmay choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.We depend on information technology systems to operate our business and a cyberattack or other breach of these systems could have a material adverse effecton our business. We rely on information technology systems to process, transmit and store electronic information in our daytoday operations. Our information technology systemscould be vulnerable to a cyberattack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks couldresult in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt ouroperations. Cyberattacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyberattacks. We have investedin our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current orpotential threats.However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technologysystems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing wereto occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes withcustomers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of adata breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results ofoperations, financial condition or cash flows.Consolidation in the healthcare industry could adversely affect our future revenues and operating income.The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systemsand other health care companies are also consolidating, resulting in greater purchasing power for these companies. Recently, one of the largest healthcare deals wasannounced with CVS Health vying to purchase Aetna, an unusual vertical merger with a supplier and customer joining forces. As a result, the disruption in thehealthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adverselyaffect our future revenues and operating income.24We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures.Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities,incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets,the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that weultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.Risks Related to our Regulatory Environment We are subject to various federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with these laws and regulations couldhave a material adverse effect on our business. Our operations are, and will continue to be, directly and indirectly affected by various federal, state and foreign healthcare laws, including, but not limited to, thosedescribed below.▪Federal AntiKickback Statute (42 U.S. Code §1320a7b), which prohibits any person or entity from knowingly and willfully offering, paying, soliciting orreceiving any remuneration, directly or indirectly, in cash or in kind, in return for or to induce the referring, ordering, leasing, purchasing or arranging for orrecommending the referring, ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made, in whole or in part, underfederal healthcare programs, such as the Medicare and Medicaid programs.▪Federal “Sunshine” (42 U.S. Code §1320a7h) law, which requires us to track and report annually to CMS information related to certain payments and other“transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals and toreport annually to CMS ownership and investment interests held by physicians, and their immediate family members. We are also subject to similar foreign“sunshine” laws or codes of conduct, which vary country by country.▪Federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, persons or entities from knowinglypresenting, or causing to be presented, a false or fraudulent claim to, or the knowing use of false records or statements to obtain payment from, or approvalby, the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of thegovernment and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines orsettlement. When an entity is determined to have violated the False Claims Act (31 U.S. Code §37293733), it may be required to pay up to three times theactual damages sustained by the government, plus civil penalties for each separate false claim. Many of the physicians that use our products will file forreimbursement from governmental programs such as Medicare and Medicaid. As a result, we may be subject to the False Claims Act if we knowingly“cause” the filing of false claims.▪Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, statute, which, among other things, created federal criminal laws thatprohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program and knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements in connection with thedelivery of or payment for healthcare benefits, items or services.25Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations,impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization onentities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially everyjurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data ProtectionDirective 95/46/EC and national implementation of the Directive in the member states of the European Union.Many states have also adopted laws similar to each of the above federal laws, such as antikickback and false claims laws, which may be broader in scope and applyto items or services reimbursed by any thirdparty payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcareprofessionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionalsand entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate ofneed prior to the installation of a radiation device, such as the SRT100. We are also subject to foreign fraud and abuse laws, which vary by country.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we maybe subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages,reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adverselyaffect our ability to operate our business and our financial results.Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improvedproducts.Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Servicesand other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinicaltesting procedures, sampling activities, an extensive agency review process, and other costly and timeconsuming procedures. It often takes several years to satisfythese requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function inhouse, we will alsobe subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazardcontrol, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:▪U.S. Food and Drug Administration Regulations (Title 21 CFR, Parts 801, 803, 806, 807 and 820);▪EU CE marking of conformity requirements depicted within the MDD (Directive 90/425/EEC);▪Health Canada requirements (SOR/98282);▪Medical Device Quality Management System requirements (ISO 13485:2003);▪Occupational Safety and Health Administration requirements;▪China CFDA requirements; and▪Other similar quality, regulatory and statutory requirements in foreign jurisdictions in which we currently market or plan to market our products in thefuture.Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale ofour products. Although we have taken steps to ensure our compliance with such state laws and regulations, our failure to fully comply with these requirementscould result in fines or penalties and could also adversely affect our ability to sell our products.Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of newproducts for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies maynot clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact themarketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they donot satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering thesuspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity fordevices or the underlying quality systems.26Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. Wecould also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business inunforeseen ways.Product deficiencies could result in field actions, recalls, substantial costs or writedowns; which could lead to the delay or termination of ongoing trials, ifany, and harm our reputation, business or financial results.Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreigngovernmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacturethat could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes toinstructions for use or if a deficiency in a device is found or suspected.Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these productsor components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or productredundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result.Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, requirethe scrapping, rework, recall or replacement of products, result in substantial costs or writeoffs, or harm our business reputation and financial results. Further, theseevents could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results andfinancial viability.A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and DrugAdministration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies ordefects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals orclearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalledproducts in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action,including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil orcriminal fines.Any identified quality issue can both harm our business reputation and result in substantial costs and writeoffs, which in either case could materially harm ourbusiness and financial results.The offlabel use or misuse of our products may harm our reputation in the marketplace, result in injuries that lead to costly product liability suits, or result incostly investigations and regulatory agency sanctions under certain circumstances.The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff andmarketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “offlabel uses.” However, if aphysician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products forindications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the offlabel use, whichcould harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an offlabel or other improper use, it couldrequest that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, awarning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action ifthey consider our business activities to constitute promotion of an offlabel use, which could result in significant penalties, including, but not limited to, criminal,civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of ouroperations. Any of these events could significantly harm our business and results of operations.27The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices.In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general publicand may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market ourproducts, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adverselyaffecting our operations as a result.We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with ourproducts, which can result in voluntary corrective actions or agency enforcement actions.Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information tothe U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injuryor has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medicaldevices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell(MEDDEV 2.121) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect ourreputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any correctiveaction, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of theforegoing would further harm our reputation and financial results.Healthcare policy changes may have a material adverse effect on our business.The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3%excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise taximposes a significant increase in the tax burden on the medical device industry, and if our efforts to offset the excise tax are unsuccessful, the increased tax burdencould have an adverse effect on our results of operations and cash flows. Although this excise tax has been suspended for 2016, 2017, 2018 and 2019 the tax remainsuncertain for future years. Other elements of this law, including comparative effectiveness research, an independent payment advisory board, payment systemreforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result infundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for proceduresutilizing our products. In addition, other legislative changes have been proposed and adopted since the law discussed above was enacted that may adversely affectour revenues. Changes to existing laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect onour business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments fromprivate payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attainprofitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed,each of which may adversely affect our operations.28Risks Related to our Intellectual PropertyIf our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operateour business profitably.Our success significantly depends on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of twoU.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure,confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process ofbeing submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitiveadvantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and TrademarkOffice may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of thesepatent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incursubstantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of ourinventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may beissued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and sellingrelated products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issuedpatents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design aroundour patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements andintellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and otherproprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell ourproducts. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may useour technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing productsto territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may notprotect intellectual property rights to the same extent as the laws of the U.S., if at all.In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and timeconsuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and timeconsuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents againstchallenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our businessmay be adversely affected.Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. Wemay be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets ofinterest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based onour trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.29The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion ofmanagement’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determiningwhether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that theirproducts, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. orforeign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applicationscan take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in thefuture. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncologydevices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings wouldplace a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claimagainst us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention ofmanagement from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that weinfringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful,and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not beavailable on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any requiredlicenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable tocommercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.Any potential intellectual property litigation also could force us to do one or more of the following:▪stop selling, making, or using products that use the disputed intellectual property;▪obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, which license may require substantial royaltypayments and may not be available on reasonable terms, or at all;▪incur significant legal expenses;▪pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;▪pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing; or▪redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible.Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third partiesmay assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf ofcustomers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers ordistributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessarylicenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.30We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secretsof competitors or are in breach of noncompetition or nonsolicitation agreements with our competitors.Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independentdistributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors haveinadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the futurebe subject to claims that we caused an employee or independent distributor to break the terms of his or her noncompetition agreement or nonsolicitationagreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result insubstantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectualproperty rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have anadverse effect on our business, financial condition and results of operations.Adverse outcomes in litigation or similar proceedings could adversely impact our business.We may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result inmonetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. If an unfavorable final outcome in any such matterbecomes probable and reasonably estimable, our financial condition could be materially and adversely affected.Risks Related to the Ownership of our SecuritiesLimited trading activity for shares of our common stock and warrants may contribute to price volatility.While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average dailytrading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2017 was approximately 9,000 shares per day. Due to thelimited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. Asa result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. Except for a required tax distribution in 2014 in the aggregate amount of $45,421, and a onetime payment in the aggregate amount of approximately $2.6 million paidto former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain ourfunds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our commonstock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may notappreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all orpart of your investment in our securities.Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance withapplicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line ofcredit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent ofthe lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operationsand earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return onyour investment.31General stock market volatility could result in significant declines in the trading price of our securities, and you could lose all or a substantial part of yourinvestment. Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad marketfluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Pricedeclines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, includingany of the risk factors described in this Annual Report on Form 10K. These broad market and industry factors may harm the market price of our securities,regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securitiesat or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:▪price and volume fluctuations in the overall stock market from time to time;▪volatility in the market prices and trading volumes of medical device company stocks;▪changes in operating performance and stock market valuations of other medical device companies generally, or those in our industry in particular;▪sales of our securities by us or our stockholders;▪failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or ourfailure to meet these estimates or the expectations of investors;▪the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;▪rumors and market speculation involving us or other companies in our industry;▪actual or anticipated changes in our results of operations or fluctuations in our results of operations;▪actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;▪litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;▪developments or disputes concerning our intellectual property or other proprietary rights;▪announced or completed acquisitions of businesses or technologies by us or our competitors;▪new laws or regulations or new interpretations of existing laws or regulations applicable to our business;▪changes in accounting standards, policies, guidelines, interpretations or principles;▪any significant change in our management; and▪general economic conditions and slow or negative growth of our markets.In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigationhas often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’sattention and resources.We are both an “emerging growth company” and a “smaller reporting company” and the reduced reporting requirements applicable to emerging growthcompanies and smaller reporting companies may make our common stock less attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, wemay take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,”including, but not limited to:▪being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, withcorrespondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;32▪not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404of the SarbanesOxley Act;▪not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory auditfirm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;▪reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and▪exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachutepayments not previously approved.We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue ofat least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by nonaffiliatesexceeds $700 million as of the prior June 30th, and (3) the date on which we have issued more than $1 billion in nonconvertible debt during the prior threeyearperiod. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as aresult of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be morevolatile.Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75 million at the end of our mostrecently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage ofcertain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of ourinternal control over financial reporting. As aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk thatmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantage of ourability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwo years of audited financialstatements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallenging for investors to analyze our results ofoperations and financial prospects, as the information we provide to stockholders may bedifferent from what one might receive from other public companies inwhich one holds shares.Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 40% of our outstanding common stock as ofDecember 31, 2017. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, includingthe election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing achange in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on themarket value of our common stock.33If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities andtrading volume could decline. The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We maybe unable to attract or sustain coverage by wellregarded securities and industry analysts. If either none or only a limited number of securities or industry analystscover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for oursecurities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover usor our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. Ifone or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities coulddecrease, which might cause the price of our securities and trading volume to decline.Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may preventattempts by our stockholders to replace or remove our current directors and management. Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition thatstockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions mayfrustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or removeour board of directors. These provisions include:▪authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;▪requiring supermajority stockholder voting to effect any merger or sale of all or substantially all of our stock our assets;▪eliminating the ability of stockholders to call and bring business before special meetings of stockholders;▪prohibiting stockholder action by written consent;▪establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on bystockholders at stockholder meetings;▪dividing our board of directors into three classes so that only one third of our directors will be up for election in any given year; and▪providing that our directors may be removed only by the affirmative vote of at least 75% of our thenoutstanding common stock and only for cause.In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an antitakeover effect with respect to transactions notapproved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares ofour common stock.These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board ofdirectors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between usand our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers oremployees. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware isthe exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claimagainst us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that isgoverned by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable fordisputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If acourt were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.34If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’views of us or our business could be harmed, resulting in a decrease in value of our common stock. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition,beginning with this annual report on Form 10K for our year ended December 31, 2017, we are required to furnish a report by management on the effectiveness of ourinternal control over financial reporting pursuant to Section 404 of the SarbanesOxley Act. In addition, our independent registered public accounting firm will berequired to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10K following the date on which weare no longer an emerging growth company, which may be up to five full years following the date of our IPO, or we are no longer a smaller reporting company. Ourcompliance with Section 404 of the SarbanesOxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we areunable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in ourinternal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject tosanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. Weexpect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our businesseffectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations tosuffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls fromour auditors when required under Section 404 of the SarbanesOxley Act. Moreover, we may not implement and maintain adequate controls over our financialprocesses and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reportingprovided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud ormisstatements or omissions.Item 1B.UNRESOLVED STAFF COMMENTSNone.Item 2.PROPERTIESOur corporate headquarters and principal office is located in Boca Raton, Florida. Our corporate headquarters and principal office occupies approximately 8,926square feet of leased space. The lease was last extended in January 2018 and will expire in September 2022. Our lease contains escalating rent clauses. Our rentalexpense in 2017 was approximately $178,000. We believe that our current facilities are suitable and adequate to meet our current needs and that suitable additionalspace will be available as and when needed on acceptable terms. Our manufacturing function is physically located at our third party manufacturer’s facility in OakRidge, Tennessee.Item 3.LEGAL PROCEEDINGSWe are party to certain legal proceedings in the ordinary course of business.

Following the completion of our initial public offering, we paid a cash dividend of approximately$2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retainedfor use in our business and no cash dividends will be paid to stockholders. Any payment of cash dividends in the future on the Company’s common stock will bedependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that the Boardof Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. Forexample, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capitalstock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Additionally, Section 170(a) of the DelawareGeneral Corporation Law (“DGCL”) only permits dividends to be declared out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out ofnet profits for the year in which the dividend is declared or the preceding year (socalled “nimble dividends”). However, dividends may not be declared out of netprofits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value ofits property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classeshaving a preference upon the distribution of assets. Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.Use of Proceeds from the Sale of Registered SecuritiesIn June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of commonstock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’full exercise of their overallotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered underthe Securities Act pursuant to a registration statement on Form S1, as amended (File No. 333209451), which was declared effective by the SEC on June 2, 2016.36We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 millionand other offering expenses of approximately $1.4 million. As of December 31, 2017, we have used approximately $2.6 million for the payment of dividends to formerpreferred investors and approximately $3.8 million to fund our operations.The remaining proceeds from the IPO have been invested in highlyliquid money market funds and debt securities with maturities of 18 months or less. There hasbeen no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under theSecurities Act on June 2, 2016.Unregistered Sales of SecuritiesThere were no unregistered sales of securities during the year ended December 31, 2017.Purchases of Equity Securities by the Registrant and Affiliated PurchasersNone.Item 6.SELECTED FINANCIAL DATANot applicable.Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSYou should read the following management’s discussion and analysis (“MD&A”) in conjunction with the information set forth within the financial statements andrelated notes included in this Annual Report on Form 10K.

Throughout this section, SensusHealthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”CAUTION CONCERNING FORWARDLOOKING STATEMENTSThis Annual Report on Form 10K, including this MD&A section, contains “forwardlooking statements” within the meaning of the Private Securities LitigationReform Act of 1995. These forwardlooking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates andintentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. Thewords “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended toidentify forwardlooking statements.All forwardlooking statements, by their nature, are subject to risks and uncertainties.

Please see the Introductory Note and Item 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actualresults to differ materially from those in the forwardlooking statements.However, other factors besides those listed in Item 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should notconsider any such list of factors to be a complete set of all potential risks or uncertainties. Any forwardlooking statements made by us or on our behalf speak onlyas of the date they are made. We do not undertake to update any forwardlooking statement, except as required by applicable law.37Components of our results of operationsWe manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment andresource allocation decisions and assesses operating performance.RevenueOur sales primarily relate to sales of our devices. We recognize product revenue upon shipment provided that there is persuasive evidence of an arrangement, thereare no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resulting receivable is reasonably assured. We donot provide a right of return related to product sales. Revenues for service contracts are recognized over the service contract period on a straightline basis.Revenue for rentals of equipment is recognized over the lease term on a straightline basis.We sell products and services under multipleelement arrangements with separate units of accounting. In these situations, total consideration is allocated to theidentified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics. A deliverable inan arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principal deliverables in ourmultiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii) service contracts.Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Other performanceobligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting. Selling pricesare established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices for thedeliverables.We operate in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior to the customerbeing able to use our products. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval is obtained andcustomer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval and deposits onproducts.We provide warranties, generally for one year, in conjunction with the sale of our products. These warranties are short term in nature and entitle the customer torepair, replacement, or modification of the defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at thetime we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.Cost of salesSince 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT100 product line, in accordance with ourproduct specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost ofsales consists of costs paid to our third party manufacturer.Gross profitWe calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including averageselling price, manufacturing costs, production volumes, product reliability and the implementation over time of costreduction strategies. Our gross profit mayfluctuate from quarter to quarter.38Selling and marketingWe focus on two primary markets private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multitiersales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multitier sales model uses a directsalesforce and international dealers and distributors.General and administrativeGeneral and administrative expense, or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our generaloperations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officerinsurance and other public company expenses.Research and developmentResearch and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred.Other income (expense)Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facilitywith Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.Income taxesUntil December 31, 2015, we were organized as a limited liability corporation (LLC) taxed as a passthrough entity and accordingly, we did not recognize a federal orstate income tax provision. Beginning in 2016, as a result of our conversion from an LLC to a Delaware corporation, we began recording a provision for income tax(benefit) expense which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in whichwe operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities vary according to the jurisdiction inwhich profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require usto exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred taxassets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Avaluation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.On December 22, 2017, new federal tax reform legislation was enacted in the United States, resulting in significant changes from previous tax law. The new tax lawreduced the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 will be basedon the new rate. The new tax law also provides for immediate deduction of 100% of the costs of qualified property that have been incurred and the property placedin service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase down by 20% per year beginning January 1, 2023 andwill be completely phased out as of January 1, 2027.InflationInflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically lowlevels of inflation.39Significant trends and uncertainties impacting our businessMany third party payors follow coverage decisions and payment amounts determined by the CMS, which administers the U.S. Medicare program, in setting theircoverage and reimbursement policies. Effective January 1, 2016 and 2017, the total reimbursement for an episode of care remained similar to the reimbursement inprior years.Results of OperationsFor the Years Ended December 31,20172016Revenues$20,587,827$14,811,175Cost of Sales6,787,8364,965,372Gross Profit13,799,9919,845,803Operating ExpensesSelling and marketing8,305,3154,915,440General and administrative3,721,6273,469,332Research and development5,490,4891,824,150Total Operating Expenses17,517,43110,208,922Loss From Operations(3,717,440)(363,119)Other Income (Expense)Interest income75,80738,538Interest expense(68,881)(21,867)Other Income (Expense), net6,92616,671Net Loss$(3,710,514)$(346,448)Year ended December 31, 2017 compared to the year ended December 31, 2016Total revenue. Total revenue was $20,587,827 for the year ended December 31, 2017 compared to $14,811,175 for the year ended December 31, 2016, an increase of$5,776,652, or 39.0%. The growth in revenue was attributable to an increase in the volume of systems sold as well as a higher percentage of sales of the higher pricedSRT100 Vision product in the current year.Total cost of sales. Cost of sales was $6,787,836 for the year ended December 31, 2017 compared to $4,965,372 for the year ended December 31, 2016, an increase of$1,822,464, or 36.7%.

Gross profit was $13,799,991 for the year ended December 31, 2017 compared to $9,845,803 for the year ended December 31, 2016, an increase of$3,954,188 or 40.2%, for the reasons discussed above. Our overall gross profit margin was 67.0% in the year ended December 31, 2017 compared to 66.5% in thecorresponding period in 2016, mainly due to increased sales of the higher margin SRT100 Vision product.Selling and marketing. Selling and marketing expense was $8,305,315 for the year ended December 31, 2017 compared to $4,915,440 for the year ended December 31,2016, an increase of $3,389,875 or 69.0%. The increase was primarily attributable to an increase in sales personnel as well as increased participation in tradeshowsand other marketing expenses.General and administrative. General and administrative expense was $3,721,627 for the year ended December 31, 2017 compared to $3,469,332 for the year endedDecember 31, 2016, an increase of $252,295, or 7.3%. The increase was primarily due to director and officer insurance and other public company expenses, anincrease in headcount, and bad debt expense, partially offset by a reduction in professional fees and stock compensation expense.40Research and development. Research and development expense was $5,490,489 for the year ended December 31, 2017 compared to $1,824,150 for the year endedDecember 31, 2016, an increase of $3,666,339 or 201.0%. The increase in research and development spending was attributable to new research projects that began inthe fourth quarter of 2016.Other income (expense). We incur interest expense in connection with our secured credit facility with Silicon Valley Bank and interest income from our investment inheldtomaturity securities and cash equivalents. We realized an immaterial decrease in other income in 2017 compared to 2016.Financial ConditionOur cash, cash equivalent and investment balance decreased from $12,608,619 at December 31, 2016 to $11,190,103 at December 31, 2017, primarily as a result of theoperating loss during 2017.Borrowings under the revolving line of credit were $2,214,970 as of December 31, 2017, compared to $0 at December 31, 2016.Liquidity and Capital ResourcesOverviewIn general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2017 and 2016, a significant source of fundinghas been from cash flows from financing activities, including our IPO in 2016, as well as from borrowings under out revolving line of credit. We believe that proceedsfrom our IPO, our borrowing capacity and our access to capital resources are sufficient to meet our future operating capital and funding requirements. Our liquidityposition and capital requirements may be impacted by a number of factors, including the following:■our ability to generate and increase revenue;■fluctuations in gross margins, operating expenses and net results; and■fluctuations in working capital.Our primary shortterm capital needs, which are subject to change, include expenditures related to:●expansion of our sales and marketing activities; and●expansion of our research and development activities.We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect toraise additional funds for these purposes in the future.Cash flowsThe following table provides a summary of our cash flows for the periods indicated:For the Years Ended December 31,20172016Net Cash Provided by (Used In):Operating Activities$(3,056,606)$(851,024)Investing Activities6,173,913(7,852,140)Financing Activities1,925,6848,680,573Total$5,042,991$(22,591)41Cash flows from operating activitiesNet cash used in operating activities was $3,056,606 for the year ended December 31, 2017, consisting of a net loss of $3,710,514 and an increase in net operatingassets of $568,857, partially offset by noncash charges of $1,222,765. The increase in net operating assets was primarily due to the increase in sales resulting in anincrease in accounts receivable and an increase in account payable and accrued expenses. Noncash charges consisted primarily of stock compensation expenseand depreciation and amortization. Net cash used in operating activities was $851,024 for the year ended December 31, 2016, consisting of a net loss of $346,448 andan increase in net operating assets of $1,601,413, offset by noncash charges of $1,096,837.Cash flows from investing activitiesNet cash provided in investing activities was $6,173,913 due to matured investments of $6,461,507 and $287,594 for acquisition of property and equipment during theyear ended December 31, 2017.

The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually.

We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis.

Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

The credit facility was amended and extended effective March 12, 2015through May 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by the Company’s eligible borrowing base of 80% of eligible accountsreceivable. On September 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to$2,000,000 and expanded the eligible accounts receivables to include certain international receivables.

As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution.

In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

Expenses related to this plan totaled approximately $95,000 and $71,000 for the years ended December 31, 2017 and 2016, respectively.NOTE 8 — STOCKHOLDERS’ EQUITYThe Company has authorized 50,000,000 shares of common stock, of which 13,522,168 were issued and 13,488,714 outstanding at December 31, 2017; 13,546,171shares were issued and outstanding as of December 31, 2016, respectively.STOCK ISSUANCESOn January 1, 2016, Sensus Healthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and changed its name to Sensus Healthcare,Inc. As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution. On July 15, 2016, the Company accrued dividends in the amount of approximately $2,553,000, representing the amount for which formerholders of membership units with a preferred return elected to receive dividends in cash. In addition, 23,138 shares valued at approximately $122,000 of commonstock were issued to those that elected to receive the dividends in shares.During 2014, the Company granted a 1% ownership interest in the Company to an executive which was to vest upon a change in control of the Company. During2015, the terms were amended such that the ownership interest will vest in the event of involuntary termination or a liquidity event, as defined. In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019. Following the first anniversary of the date of issuance, if certain conditions are met, the Company may redeem any andall of the outstanding warrants at a price equal to $0.01 per warrant.In addition, the underwriter’s representatives received fouryear warrants to purchase up to 138,000 units, consisting of one share of common stock and one warrantto purchase one share of common stock. The warrants for the units are exercisable between June 2, 2017 and June 2, 2021 at an exercise price of $6.75 per unit.The following table summarizes the Company’s warrant activity:Common Unit WarrantsNumber ofWarrantsWeightedAverageExercisePriceWeightedAverageRemainingContractualTerm (In Years)Outstanding – December 31, 20162,524,376$6.672.50Granted———Exercised———Forfeited———Outstanding – December 31, 20172,524,376$6.671.50Exercisable – December 31, 20172,524,376$6.671.50The intrinsic value of the common stock warrants was approximately $19,000 as of December 31, 2017, and $114,000 as of December 31, 2016.2016 AND 2017 EQUITYINCENTIVE PLANSThe Company has limited the aggregate number of shares of common stock to be awarded under the 2016 Equity Incentive Plan to 397,473 shares and no more than397,473 shares of common stock in the aggregate may be granted in connection with incentive stock options. The Company has limited the aggregate number ofshares of common stock to be awarded under the 2017 Equity Incentive Plan to 500,000 shares and no more than 500,000 shares of common stock in the aggregatemay be granted in connection with incentive stock options. In addition, unless the Compensation Committee specifically determines otherwise, the maximum numberof shares available under the 2016 and 2017 Plans and the awards granted under those plans will be subject to appropriate adjustment in the case of any stockdividends, stock splits, recapitalizations, reorganizations, mergers, consolidations, exchanges or other changes in capitalization affecting our common stock.On June 2, 2016, 307,666 shares of restricted stock were issued to employees and were recorded at the fair value of $5.25 as per the initial offering price. In addition,on January 20, 2017, 10,000 shares of restricted stock were issued to one employee and were recorded at the fair value of $4.99 per share.

As of December 31, 2017, 84,807 shares wereavailable to be granted under the 2016 Plan and 500,000 shares were available to be granted under the 2017 Plan.58The Company recognizes forfeitures as they occur rather than estimating a forfeiture rate. The reduction of stock compensation expense related to the 5,000 sharesforfeited for the year ended in December 31, 2017 was approximately $7,000.A summary of the restricted stock activity for the year ended December 31, 2017 is presented as follows:SharesWeighted AverageGrant Date FairValueUnvested balance at December 31, 2016412,914$5.04Granted10,0004.99Vested(180,914)4.24Forfeited(5,000)5.25Unvested balance at December 31, 2017237,000$5.64TREASURY STOCKThe Company accounts for purchases of treasury stock under the cost method with the cost of such share purchases reflected in treasury stock in theaccompanying condensed balance sheet.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty.

Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred.

ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

The credit facility was amended and extended effective March 12, 2015through May 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by the Company’s eligible borrowing base of 80% of eligible accountsreceivable. On September 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to$2,000,000 and expanded the eligible accounts receivables to include certain international receivables. The Company was not in compliance in April and May 2017with one of its financial covenants. On June 27, 2017, the covenant defaults were waived and the agreement was amended to modify the financial covenantseffective June 2017. An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017. On October 31, 2017, theCompany amended its revolving credit facility to extend the maturity to October 31, 2019.

As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution. On July 15, 2016, the Company accrued dividends in the amount of approximately $2,553,000, representing the amount for which formerholders of membership units with a preferred return elected to receive dividends in cash. In addition, 23,138 shares valued at approximately $122,000 of commonstock were issued to those that elected to receive the dividends in shares.During 2014, the Company granted a 1% ownership interest in the Company to an executive which was to vest upon a change in control of the Company. During2015, the terms were amended such that the ownership interest will vest in the event of involuntary termination or a liquidity event, as defined. In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

The warrants for the units are exercisable between June 2, 2017 and June 2, 2021 at an exercise price of $6.75 per unit.The following table summarizes the Company’s warrant activity:Common Unit WarrantsNumber ofWarrantsWeightedAverageExercisePriceWeightedAverageRemainingContractualTerm (In Years)Outstanding – December 31, 20162,524,376$6.672.50Granted———Exercised———Forfeited———Outstanding – December 31, 20172,524,376$6.671.50Exercisable – December 31, 20172,524,376$6.671.50The intrinsic value of the common stock warrants was approximately $19,000 as of December 31, 2017, and $114,000 as of December 31, 2016.2016 AND 2017 EQUITYINCENTIVE PLANSThe Company has limited the aggregate number of shares of common stock to be awarded under the 2016 Equity Incentive Plan to 397,473 shares and no more than397,473 shares of common stock in the aggregate may be granted in connection with incentive stock options. The Company has limited the aggregate number ofshares of common stock to be awarded under the 2017 Equity Incentive Plan to 500,000 shares and no more than 500,000 shares of common stock in the aggregatemay be granted in connection with incentive stock options.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

The Company is not required to have, nor were weengaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control overfinancial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting.

Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

Expenses related to this plan totaled approximately $95,000 and $71,000 for the years ended December 31, 2017 and 2016, respectively.NOTE 8 — STOCKHOLDERS’ EQUITYThe Company has authorized 50,000,000 shares of common stock, of which 13,522,168 were issued and 13,488,714 outstanding at December 31, 2017; 13,546,171shares were issued and outstanding as of December 31, 2016, respectively.STOCK ISSUANCESOn January 1, 2016, Sensus Healthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and changed its name to Sensus Healthcare,Inc. As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution. On July 15, 2016, the Company accrued dividends in the amount of approximately $2,553,000, representing the amount for which formerholders of membership units with a preferred return elected to receive dividends in cash.

During2015, the terms were amended such that the ownership interest will vest in the event of involuntary termination or a liquidity event, as defined. In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

The warrants for the units are exercisable between June 2, 2017 and June 2, 2021 at an exercise price of $6.75 per unit.The following table summarizes the Company’s warrant activity:Common Unit WarrantsNumber ofWarrantsWeightedAverageExercisePriceWeightedAverageRemainingContractualTerm (In Years)Outstanding – December 31, 20162,524,376$6.672.50Granted———Exercised———Forfeited———Outstanding – December 31, 20172,524,376$6.671.50Exercisable – December 31, 20172,524,376$6.671.50The intrinsic value of the common stock warrants was approximately $19,000 as of December 31, 2017, and $114,000 as of December 31, 2016.2016 AND 2017 EQUITYINCENTIVE PLANSThe Company has limited the aggregate number of shares of common stock to be awarded under the 2016 Equity Incentive Plan to 397,473 shares and no more than397,473 shares of common stock in the aggregate may be granted in connection with incentive stock options. The Company has limited the aggregate number ofshares of common stock to be awarded under the 2017 Equity Incentive Plan to 500,000 shares and no more than 500,000 shares of common stock in the aggregatemay be granted in connection with incentive stock options.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017and 2016, and the results of its operations and its cash flows for each of the 2 years in the period ended December 31, 2017, in conformity with accounting principlesgenerally accepted in the United States of America.Basis for OpinionThese financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statementsbased on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are requiredto be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities andExchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonableassurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were weengaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control overfinancial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, weexpress no such opinion.Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performingprocedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financialstatements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overallpresentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.Marcum LLP/S/ Marcum LLPWe have served as the Company’s auditor since 2012.West Palm Beach, FLFebruary 15, 201845SENSUS

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

Expenses related to this plan totaled approximately $95,000 and $71,000 for the years ended December 31, 2017 and 2016, respectively.NOTE 8 — STOCKHOLDERS’ EQUITYThe Company has authorized 50,000,000 shares of common stock, of which 13,522,168 were issued and 13,488,714 outstanding at December 31, 2017; 13,546,171shares were issued and outstanding as of December 31, 2016, respectively.STOCK ISSUANCESOn January 1, 2016, Sensus Healthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and changed its name to Sensus Healthcare,Inc. As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution. On July 15, 2016, the Company accrued dividends in the amount of approximately $2,553,000, representing the amount for which formerholders of membership units with a preferred return elected to receive dividends in cash.

During2015, the terms were amended such that the ownership interest will vest in the event of involuntary termination or a liquidity event, as defined. In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

The warrants for the units are exercisable between June 2, 2017 and June 2, 2021 at an exercise price of $6.75 per unit.The following table summarizes the Company’s warrant activity:Common Unit WarrantsNumber ofWarrantsWeightedAverageExercisePriceWeightedAverageRemainingContractualTerm (In Years)Outstanding – December 31, 20162,524,376$6.672.50Granted———Exercised———Forfeited———Outstanding – December 31, 20172,524,376$6.671.50Exercisable – December 31, 20172,524,376$6.671.50The intrinsic value of the common stock warrants was approximately $19,000 as of December 31, 2017, and $114,000 as of December 31, 2016.2016 AND 2017 EQUITYINCENTIVE PLANSThe Company has limited the aggregate number of shares of common stock to be awarded under the 2016 Equity Incentive Plan to 397,473 shares and no more than397,473 shares of common stock in the aggregate may be granted in connection with incentive stock options. The Company has limited the aggregate number ofshares of common stock to be awarded under the 2017 Equity Incentive Plan to 500,000 shares and no more than 500,000 shares of common stock in the aggregatemay be granted in connection with incentive stock options.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017and 2016, and the results of its operations and its cash flows for each of the 2 years in the period ended December 31, 2017, in conformity with accounting principlesgenerally accepted in the United States of America.Basis for OpinionThese financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statementsbased on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are requiredto be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities andExchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonableassurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were weengaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control overfinancial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, weexpress no such opinion.Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performingprocedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financialstatements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overallpresentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.Marcum LLP/S/ Marcum LLPWe have served as the Company’s auditor since 2012.West Palm Beach, FLFebruary 15, 201845SENSUS

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

Expenses related to this plan totaled approximately $95,000 and $71,000 for the years ended December 31, 2017 and 2016, respectively.NOTE 8 — STOCKHOLDERS’ EQUITYThe Company has authorized 50,000,000 shares of common stock, of which 13,522,168 were issued and 13,488,714 outstanding at December 31, 2017; 13,546,171shares were issued and outstanding as of December 31, 2016, respectively.STOCK ISSUANCESOn January 1, 2016, Sensus Healthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and changed its name to Sensus Healthcare,Inc. As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution. On July 15, 2016, the Company accrued dividends in the amount of approximately $2,553,000, representing the amount for which formerholders of membership units with a preferred return elected to receive dividends in cash.

During2015, the terms were amended such that the ownership interest will vest in the event of involuntary termination or a liquidity event, as defined. In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

The warrants for the units are exercisable between June 2, 2017 and June 2, 2021 at an exercise price of $6.75 per unit.The following table summarizes the Company’s warrant activity:Common Unit WarrantsNumber ofWarrantsWeightedAverageExercisePriceWeightedAverageRemainingContractualTerm (In Years)Outstanding – December 31, 20162,524,376$6.672.50Granted———Exercised———Forfeited———Outstanding – December 31, 20172,524,376$6.671.50Exercisable – December 31, 20172,524,376$6.671.50The intrinsic value of the common stock warrants was approximately $19,000 as of December 31, 2017, and $114,000 as of December 31, 2016.2016 AND 2017 EQUITYINCENTIVE PLANSThe Company has limited the aggregate number of shares of common stock to be awarded under the 2016 Equity Incentive Plan to 397,473 shares and no more than397,473 shares of common stock in the aggregate may be granted in connection with incentive stock options. The Company has limited the aggregate number ofshares of common stock to be awarded under the 2017 Equity Incentive Plan to 500,000 shares and no more than 500,000 shares of common stock in the aggregatemay be granted in connection with incentive stock options.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017and 2016, and the results of its operations and its cash flows for each of the 2 years in the period ended December 31, 2017, in conformity with accounting principlesgenerally accepted in the United States of America.Basis for OpinionThese financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statementsbased on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are requiredto be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities andExchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonableassurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were weengaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control overfinancial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, weexpress no such opinion.Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performingprocedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financialstatements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overallpresentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.Marcum LLP/S/ Marcum LLPWe have served as the Company’s auditor since 2012.West Palm Beach, FLFebruary 15, 201845SENSUS

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

Expenses related to this plan totaled approximately $95,000 and $71,000 for the years ended December 31, 2017 and 2016, respectively.NOTE 8 — STOCKHOLDERS’ EQUITYThe Company has authorized 50,000,000 shares of common stock, of which 13,522,168 were issued and 13,488,714 outstanding at December 31, 2017; 13,546,171shares were issued and outstanding as of December 31, 2016, respectively.STOCK ISSUANCESOn January 1, 2016, Sensus Healthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and changed its name to Sensus Healthcare,Inc. As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution. On July 15, 2016, the Company accrued dividends in the amount of approximately $2,553,000, representing the amount for which formerholders of membership units with a preferred return elected to receive dividends in cash.

During2015, the terms were amended such that the ownership interest will vest in the event of involuntary termination or a liquidity event, as defined. In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

The warrants for the units are exercisable between June 2, 2017 and June 2, 2021 at an exercise price of $6.75 per unit.The following table summarizes the Company’s warrant activity:Common Unit WarrantsNumber ofWarrantsWeightedAverageExercisePriceWeightedAverageRemainingContractualTerm (In Years)Outstanding – December 31, 20162,524,376$6.672.50Granted———Exercised———Forfeited———Outstanding – December 31, 20172,524,376$6.671.50Exercisable – December 31, 20172,524,376$6.671.50The intrinsic value of the common stock warrants was approximately $19,000 as of December 31, 2017, and $114,000 as of December 31, 2016.2016 AND 2017 EQUITYINCENTIVE PLANSThe Company has limited the aggregate number of shares of common stock to be awarded under the 2016 Equity Incentive Plan to 397,473 shares and no more than397,473 shares of common stock in the aggregate may be granted in connection with incentive stock options. The Company has limited the aggregate number ofshares of common stock to be awarded under the 2017 Equity Incentive Plan to 500,000 shares and no more than 500,000 shares of common stock in the aggregatemay be granted in connection with incentive stock options.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017and 2016, and the results of its operations and its cash flows for each of the 2 years in the period ended December 31, 2017, in conformity with accounting principlesgenerally accepted in the United States of America.Basis for OpinionThese financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statementsbased on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are requiredto be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities andExchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonableassurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were weengaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control overfinancial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, weexpress no such opinion.Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performingprocedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financialstatements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overallpresentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.Marcum LLP/S/ Marcum LLPWe have served as the Company’s auditor since 2012.West Palm Beach, FLFebruary 15, 201845SENSUS

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

Expenses related to this plan totaled approximately $95,000 and $71,000 for the years ended December 31, 2017 and 2016, respectively.NOTE 8 — STOCKHOLDERS’ EQUITYThe Company has authorized 50,000,000 shares of common stock, of which 13,522,168 were issued and 13,488,714 outstanding at December 31, 2017; 13,546,171shares were issued and outstanding as of December 31, 2016, respectively.STOCK ISSUANCESOn January 1, 2016, Sensus Healthcare, LLC converted into a Delaware corporation pursuant to a statutory conversion and changed its name to Sensus Healthcare,Inc. As a result of the corporate conversion, the holders of the different classes of units of Sensus Healthcare, LLC became holders of common stock of SensusHealthcare, Inc. Holders of warrants and options, respectively, to purchase membership interests of Sensus Healthcare, LLC became holders of warrants and optionsto purchase common stock of Sensus Healthcare, Inc., respectively. Each membership interest converted to one share of common stock.During 2011, the Company offered to a limited number of investors (the “investor members”) preferred membership interests (the “interests”) consisting of (i)cumulative, noncompounded, 8% per annum preferential return, payable annually, if and when such distributions are made by the Company’s board of directors and(ii) participation in the Company’s net profits, net losses and distributions of the Company’s assets pursuant to the operating agreement. The offering raisedapproximately $6.4 million in gross proceeds ($6.0 million net of offering costs), utilizing a private placement memorandum. As of December 31, 2015, accumulatedunpaid preferential distributions were approximately $2,674,000 ($0.87 per share). Preferential distributions no longer accrued after December 31, 2015. In June 2016,after the completion of the IPO, the accumulated unpaid distribution as of December 31, 2015 was payable in cash or shares, at the option of each stockholder with apreferential distribution. On July 15, 2016, the Company accrued dividends in the amount of approximately $2,553,000, representing the amount for which formerholders of membership units with a preferred return elected to receive dividends in cash.

During2015, the terms were amended such that the ownership interest will vest in the event of involuntary termination or a liquidity event, as defined. In accordance withaccounting principles generally accepted in the United States, compensation cost for awards with performance conditions should be recorded in the Company’sfinancial statements at which time that it is probable the performance condition is achieved. As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

The warrants for the units are exercisable between June 2, 2017 and June 2, 2021 at an exercise price of $6.75 per unit.The following table summarizes the Company’s warrant activity:Common Unit WarrantsNumber ofWarrantsWeightedAverageExercisePriceWeightedAverageRemainingContractualTerm (In Years)Outstanding – December 31, 20162,524,376$6.672.50Granted———Exercised———Forfeited———Outstanding – December 31, 20172,524,376$6.671.50Exercisable – December 31, 20172,524,376$6.671.50The intrinsic value of the common stock warrants was approximately $19,000 as of December 31, 2017, and $114,000 as of December 31, 2016.2016 AND 2017 EQUITYINCENTIVE PLANSThe Company has limited the aggregate number of shares of common stock to be awarded under the 2016 Equity Incentive Plan to 397,473 shares and no more than397,473 shares of common stock in the aggregate may be granted in connection with incentive stock options. The Company has limited the aggregate number ofshares of common stock to be awarded under the 2017 Equity Incentive Plan to 500,000 shares and no more than 500,000 shares of common stock in the aggregatemay be granted in connection with incentive stock options.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.

Net cash provided by financing activities was $8,680,573 during the year ended December 31,2016 mostly from the net proceeds of our IPO.IndebtednessOn March 12, 2013, we entered into a twoyear $3 million revolving credit facility. The credit facility was amended and extended effective March 12, 2015 throughMay 12, 2017. The maximum borrowing was reduced to $1,500,000 and was limited by our eligible borrowing base of 80% of eligible accounts receivable. OnSeptember 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2,000,000 andexpanded the eligible accounts receivables to include certain international receivables. We were not in compliance in April and May 2017 with one of our financialcovenants. On June 27, 2017, the covenant defaults were waived and the agreement was further amended to modify the financial covenants effective June 27, 2017.An amendment signed on September 15, 2017 extended the maturity date of the credit line through November 19, 2017 and on October 31, 2017, we again amendedour revolving credit facility to extend the maturity to October 31, 2019. The amount of credit available under the amended facility will equal the lesser of the $5 millioncommitment amount or the borrowing base plus the $2.5 million nonformula sublimit. The borrowing base consists of 80% of eligible accounts receivable, asdefined in the agreement.Interest, at Prime plus 0.75% (5.25% at December 31, 2017) and Prime plus 1.50% on nonformula borrowings (6.00% at December 31, 2017), is payable monthly, andthe outstanding principal and interest are due on the maturity date. The facility is secured by all of our assets and limits the amount of additional indebtedness,restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant, as defined in theagreement. Approximately $2,215,000 was outstanding under the revolving credit facility at December 31, 2017 and $0 at December 31, 2016. We pay commitment feesof 0.25% per annum on the average unused portion of the line of credit.Contractual Obligations and CommitmentsOur only longterm contractual commitment is the lease of our office space in Boca Raton, Florida. In July 2016, we renewed our lease and expanded our office spacefrom 4,551 to 8,028 square feet. The lease expires in September 2022 and lease payments increase by 3% annually. Future minimum lease payments as of December31, 2017 are as follows:YearMinimum LeasePayment2018190,0002019196,0002020202,0002021208,0002022160,000Total$956,00042OffBalance Sheet ArrangementsWe did not have during the periods presented, and do not currently have, any offbalance sheet arrangements.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance withgenerally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial conditionand results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements includedin this Annual Report on Form 10K.JOBS ActWe qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may takeadvantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the SarbanesOxley Act, reduced disclosureobligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financialstatements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory“sayonpay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reducedreporting obligations and executive compensation disclosure in this Annual Report on Form 10K, and expect to continue to avail ourselves of the reduced reportingobligations available to emerging growth companies in future filings.In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies.However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on therelevant dates on which nonemerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of theextended transition period for complying with new or revised accounting standards is irrevocable.Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKNot applicable.43Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFINANCIAL STATEMENTS OF SENSUS HEALTHCARE, INC.CONTENTSReport of Independent Registered Public Accounting Firm45Financial StatementsBalance Sheets as of December 31, 2017 and 201646Statements of Operations for the years ended December 31, 2017 and 201647Statements of Stockholders’ Equity for the years ended December 31, 2017 and 201648Statements of Cash Flows for the years ended December 31, 2017 and 201649Notes to financial statements5044REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of Directors ofSensus Healthcare, Inc.Opinion on the Financial StatementsWe have audited the accompanying balance sheets of Sensus Healthcare, Inc.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017and 2016, and the results of its operations and its cash flows for each of the 2 years in the period ended December 31, 2017, in conformity with accounting principlesgenerally accepted in the United States of America.Basis for OpinionThese financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statementsbased on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are requiredto be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities andExchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonableassurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were weengaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control overfinancial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, weexpress no such opinion.Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performingprocedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financialstatements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overallpresentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.Marcum LLP/S/ Marcum LLPWe have served as the Company’s auditor since 2012.West Palm Beach, FLFebruary 15, 201845SENSUS

POLICIESDESCRIPTIONOFTHE BUSINESSSensus Healthcare, Inc. (the “Company”) is a manufacturer of superficial radiation therapy devices and has established a distribution and marketing network to sellthe devices to healthcare providers globally. The Company was organized on May 7, 2010 as a limited liability corporation. On January 1, 2016, the Companycompleted a corporate conversion pursuant to which Sensus Healthcare, Inc. succeeded to the business of Sensus Healthcare, LLC. The Company operates as onesegment from its corporate headquarters located in Boca Raton, Florida.INITIAL PUBLIC OFFERINGIn June 2016, the Company issued 2,300,000 units in its initial public offering (“IPO”) at a price of $5.50 per unit ($5.25 attributable to the common stock and $0.25attributable to the warrant), for net proceeds of approximately $10,393,000 after deducting underwriting discounts and commissions of $886,000 and expenses of$1,371,000. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock. Immediately prior to the IPO, all shares ofstock then outstanding converted into an aggregate of 10,367,883 shares of common stock following a 241.95forone forward stock split approved by theCompany’s board of directors. On July 25, 2016, the common stock and warrants included in the units issued in the IPO commenced trading separately under thesymbols “SRTS” and “SRTSW,” respectively, and trading of the units under the symbol “SRTSU” was suspended.USEOF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements andthe reported amounts of revenues and expenses during the reporting period. Significant estimates to which it is reasonably possible that a change could occur in thenear term include, revenue recognition, inventory reserves, receivable allowances, recoverability of long lived assets and estimation of the Company’s productwarranties. Actual results could differ from those estimates.REVENUE RECOGNITIONThe Company’s sales primarily relate to sales of the Company’s devices. The Company recognizes product revenue upon shipment provided that there is persuasiveevidence of an arrangement, there are no uncertainties regarding customer acceptance, the sales price is fixed and determinable, and collection of the resultingreceivable is reasonably assured. The Company does not provide a right of return related to product sales. Revenues for service contracts are recognized over theservice contract period on a straightline basis. Revenue for rentals of equipment is recognized over the lease term on a straightline basis.The Company sells products and services under multipleelement arrangements with separate units of accounting; in these situations, total consideration isallocated to the identified units of accounting based on their relative selling prices and revenue is then recognized for each unit based on its specific characteristics.A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a standalone basis. The principaldeliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of medical devices and accessories and (ii)service contracts. Service contracts are considered a performance obligation only if they provide a material right, otherwise they are considered options. Otherperformance obligations, including installation and customer training, are considered inconsequential and are combined with the product as one unit of accounting.Selling prices are established using vendorspecific objective evidence (VSOE). If VSOE does not exist, the Company uses its best estimate of the selling prices forthe deliverables.50The Company operates in a highlyregulated environment and is continually entering into new markets in which regulatory approval is sometimes required prior tothe customer being able to use the product. In these cases, where regulatory approval is pending, revenue is deferred until such time as regulatory approval isobtained and customer acceptance becomes certain.Deferred revenue consists of payments from customers for long term separately priced service contracts, sales pending regulatory approval, and deposits onproducts. Deferred revenue as of December 31, 2017 and 2016 was as follows:As of December 31,20172016Service contracts$570,242$613,374Sales pending regulatory approval—155,517Deposits on products82,00084,907Total deferred revenue, current portion$652,242$853,798Service contracts, net of current portion73,08316,251Total deferred revenue$725,325$870,049The Company provides warranties, generally for one year, in conjunction with the sale of its product. These warranties are short term in nature and entitle thecustomer to repair, replacement, or modification of the defective product subject to the terms of the respective warranty. The Company records an estimate of futurewarranty claims at the time the Company recognizes revenue from the sale of the product based upon management’s estimate of the future claims rate.Shipping and handling costs are expensed as incurred and are included in cost of sales.CONCENTRATIONOF CREDIT RISKFinancial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, accounts receivable andinvestments in debt securities.SEGMENTAND GEOGRAPHICAL INFORMATIONThe Company’s revenue is generated primarily from customers in the United States, which represented approximately 97% and 81% of revenue for the years endedDecember 31, 2017 and 2016, respectively. A customer in China accounted for approximately 2% and 10% of revenue for the years ended December 31, 2017 and2016, respectively. A customer in the U.S. accounted for approximately 59% and 20% of revenue for the years ended December 31, 2017 and 2016, respectively, and87% and 39% of the accounts receivable as of December 31, 2017 and 2016, respectively.FAIR VALUEOF FINANCIAL INSTRUMENTSCarrying amounts of cash equivalents, accounts receivable, accounts payable, accrued liabilities and revolving credit facility approximate fair value due to theirrelative short maturities.CASHAND CASH EQUIVALENTSThe Company maintains its cash and cash equivalents with financial institutions which balances exceed the federally insured limits. Federally insured limits are$250,000 for deposits. As of December 31, 2017 and 2016, the Company had approximately $9,952,000 and $4,792,000, respectively in excess of federally insuredlimits.For purposes of the statement of cash flows, the Company considers all highly liquid financial instruments with a maturity of three months or less when purchasedto be a cash equivalent.51INVESTMENTSShort term investments consist of investments which the Company expects to convert into cash within one year and longterm investments after one year. TheCompany classifies its investments in debt securities at the time of purchase as heldtomaturity and reevaluates such classification on a quarterly basis. Heldtomaturity investments consist of securities that the Company has the intent and ability to retain until maturity. These securities are carried at amortized cost plusaccrued interest and consist of the following:Amortized CostGrossUnrealizedGainGrossUnrealizedLossFairValueShort Term:Corporate bonds$6,462,369$167$7,243$6,455,293Total Short Term:6,462,3691677,2436,455,293Long Term:United States Treasury bonds502,063—1,174500,890Corporate bonds601,7102,618599,091Total Long Term:1,103,773—3,7921,099,981Total Investments December 31, 2016$7,566,142$167$11,035$7,555,274Short Term:Corporate bonds$602,599$—$256$602,343United States Treasury bonds502,036—332501,704Total Short Term:1,104,635—5881,104,047Total Investments December 31, 2017$1,104,635$—$588$1,104,047ACCOUNTS RECEIVABLEThe Company does business and extends credit based on an evaluation of each customer’s financial condition, generally without requiring collateral. Exposure tolosses on receivables is expected to vary by customer due to the financial condition of each customer. The Company monitors exposure to credit losses andmaintains allowances for anticipated losses considered necessary under the circumstances. The allowance for doubtful accounts was approximately $16,000 and$29,000 as of December 31, 2017 and 2016, respectively. Bad debt expense for the years ended December 31, 2017 and 2016 was approximately $191,000 and $33,000,respectively.INVENTORIESInventories consist of finished product and components and are stated at the lower of cost and net realizable value, determined using the firstinfirstout method.PROPERTYAND EQUIPMENTProperty and equipment are stated at cost. Depreciation on property and equipment is calculated on the straightline basis over the estimated useful lives of theassets. Maintenance and repairs are expensed as incurred; expenditures that enhance the value of property or extend their useful lives are capitalized. When assetsare sold or returned, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in income.Inventory units designated for customer demonstrations, as part of the sales process, are reclassified to property and equipment and the depreciation is recorded toselling and marketing expense. The inventory used for demonstrations that was reclassified to property and equipment for the years ended December 31, 2017 and2016 was approximately $35,000 and $68,000, respectively.52Inventory units designated for customer rental agreements are reclassified to property and equipment and the depreciation is recorded to cost of sales.INTANGIBLE ASSETSIntangible assets are comprised of the Company’s patent rights and are amortized over the patents’ estimated useful life of approximately 13 years. As of December31, 2017, the remaining useful life was 66 months.LONGLIVED ASSETSThe Company evaluates its longlived assets, including intangible assets, for possible impairment whenever circumstances indicate that the carrying amount of theasset, or related group of assets, may not be recoverable from estimated future cash flows in accordance with accounting guidance. If circumstances suggest therecorded amounts cannot be recovered, based upon estimated future undiscounted cash flows, the carrying values of such assets are reduced to fair value. Noimpairment charges were recorded for longlived assets for the years ended December 31, 2017 and 2016.RESEARCHAND DEVELOPMENTResearch and development costs related to products under development by the Company and quality and regulatory costs and are expensed as incurred.EARNINGS PER SHAREBasic net income (loss) per share is calculated by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the periodusing the treasury stock method for options and warrants. The diluted net income per share is computed by giving effect to all potential dilutive common shareequivalents outstanding for the period. In periods when the Company has incurred a net loss, options and warrants to purchase common shares are consideredcommon share equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Shares excluded were computedunder the treasury stock method as follows:For the Years Ended December 31,20172016Warrants4,07619,489Unvested shares—72,670EQUITYBASED COMPENSATIONPursuant to accounting guidance related to accounting for equitybased compensation, the Company is required to recognize all sharebased payments to nonemployees and employees in the financial statements based on fair values on the grant date. The Company has accounted for issuance of shares, options, andwarrants in accordance with the guidance, which requires the recognition of expense, based on grantdate fair values, over the service period, generally periods overwhich the shares, options and warrants vest.ADVERTISING COSTSAdvertising and promotion expenses are charged to expense as incurred. Advertising and promotion expense included in selling and marketing expense in theaccompanying statements of operations amounted to approximately $1,684,000 and $1,051,000 for the years ended December 31, 2017 and 2016, respectively.53OPERATING LEASESRent expense for operating leases which contain escalating rental clauses is recorded on a straightline basis over the lease term.RECENTLYISSUEDACCOUNTINGPRONOUNCEMENTSIn May 2014, the FASB issued ASU 201409, Revenue from Contracts with Customers (Topic 606). ASU 201409 eliminated transaction and industryspecificrevenue recognition guidance under current GAAP and replaced it with a principle based approach for determining revenue recognition. ASU 201409 requires thatcompanies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also requires additional disclosure aboutthe nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgmentsand assets recognized from costs incurred to obtain or fulfill a contract. ASU 201409 is effective for reporting periods beginning after December 15, 2017. Entitiescan transition to the standard either retrospectively or as a cumulativeeffect adjustment as of the date of adoption. In April 2016, the FASB also issued ASU 201610, Identifying Performance Obligations and Licensing, implementation guidance on principal versus agent, identifying performance obligations, and licensing. ASU201610 is effective for reporting periods beginning after December 15, 2017. Entities can transition to the standard either retrospectively or as a cumulativeeffectadjustment as of the date of adoption. The Company has completed the evaluation of this ASU impact on the results of operations and financial condition. TheCompany has concluded, after completing a detailed contract review, that the adoption of the new standard does not have a material impact on the financial resultsand determined that no material adjustments were necessary to the existing accounting policies. The Company will adopt the modified retrospective method ofadoption on January 1, 2018.In November 2015, the FASB issued ASU 201517, Balance Sheet Classification of Deferred Taxes (Topic 740). Under the new guidance, companies are required toclassify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Inaddition, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances will also be classifiedas noncurrent. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016. The Company adopted this standardin the first quarter of 2017 and it did not have a material impact on its financial statements.In February 2016, the FASB issued ASU No. 201602, “Leases (Topic 842).” The guidance in ASU 201602 supersedes the lease recognition requirements in ASCTopic 840, Leases (FAS 13). The new standard establishes a rightofuse (ROU) model that requires a lessee to record a ROU asset and a lease liability on thebalance sheet for leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expenserecognition in the income statement. The new standard is effective for fiscal years beginning after December 1, 2018, including interim periods within those fiscalyears, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered intoafter, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. TheCompany is currently evaluating the effect this standard will have on its financial statements.In April 2016, the FASB issued ASU 201609, Compensation — Stock Compensation (Topic 718), which requires that the income tax effect of sharebased awards berecognized in the income statement when the awards vest or are settled. The guidance will also allow an employer to repurchase more of an employee’s shares for taxwithholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The guidance is effective foryears beginning after December 15, 2016 and interim periods within those years. The Company adopted this standard in the first quarter of 2017 and it did not have amaterial impact on its financial statements.54NOTE 2 — PROPERTYAND EQUIPMENTAs of December 31,Estimated20172016Useful LivesOperations and rental equipment$542,639$630,8863 yearsTradeshow and demo equipment271,275294,4753 yearsComputer equipment94,29895,2183 years908,2121,020,579Less accumulated depreciation(514,134)(587,171)Property and Equipment, Net$394,078$433,408Depreciation expense was approximately $292,000 and $241,000 for the years ended December 31, 2017 and 2016, respectively.

As of December 31, 2015, the achievement of the performance conditionwas not probable and accordingly no compensation cost was recorded. Following the IPO in June 2016, the performance condition was met and accordingly, stockcompensation expense of approximately $465,000 was recorded in 2016. The grant date fair value of the equity award was estimated using both an income and marketapproach. Under the income approach, the Company used a discounted cash flow method based on Company projections, historical financial information andguideline company/industry growth and margin indicators. The discount rate applied was based on the weighted average cost of capital of guideline publiccompanies and was estimated at approximately 21%. The Company also used a market approach to estimate its enterprise value based on a multiple of revenue andearnings of guideline public companies. Using both of these approaches, management was able to estimate the fair value per share on the grant date which wasapproximately $4.42 per share or approximately $465,000.57WARRANTSIn April 2013, the closing date of the second common offering, the Company’s placement agent received investor rights to 5 year warrants to purchase 86,376common shares of the Company at an exercise price of $4.55 per unit, which was equal to 110% of the offering price.In June 2016, from the IPO, the investors received threeyear warrants to purchase 2,300,000 shares of common stock at an exercise price of $6.75 per share; thewarrants are exercisable through June 2, 2019.

These net operating loss carryforwards, if not used toreduce taxable income in future periods, will begin to expire in 2029, for both federal and state tax purposes. Additionally, the Company also has federal Researchand Development tax credit carryforwards of approximately $156,000 as of December 31, 2017. These credit carryforwards, if not used in future periods, will begin toexpire in 2029.In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will berealized. The ultimate realization of deferred tax assets is dependent upon the future generation of taxable income during the periods in which those temporarydifferences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and taxing strategies inmaking this assessment. Based on this assessment, management has established a full valuation allowance against all of the net deferred tax assets for each period,since it is more likely than not that all of the deferred tax assets will not be realized. The valuation allowance for the years ended December 31, 2017 and 2016increased by approximately $881,000 and $149,000, respectively. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financialstatements as of December 31, 2017 and 2016. The Company does not expect any significant changes in its unrecognized tax benefits within 12 months of thereporting date. The Company has U.S. federal and certain state tax returns subject to examination by tax authorities beginning with those filed for the year endedDecember 31, 2014. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrativeexpenses in the consolidated statements of operations.On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to as the “Tax Cuts and Jobs Act” (the “Act”),resulting in significant modifications to existing law. The Company has completed the accounting for the effects of the Act during this period. Our financialstatements for the year ended December 31, 2017, reflect certain effects of the Act which includes a reduction in the corporate tax rate from 35% to 21%, as well asother changes. As a result of the changes to tax laws and tax rates under the Act, the Company incurred an incremental increase in income tax expense ofapproximately $562,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities from 35% to21%. This incremental amount was offset by a change to the Company’s valuation allowance resulting in no net effect.60NOTE 10 — SUBSEQUENT EVENTSThe Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued forpotential recognition or disclosure. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financialstatements.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone.Item 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Control and ProceduresAs of December 31, 2017, the end of the period covered by this Annual Report on Form 10K, our management, including our Chief Executive Officer and ChiefFinancial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a15(e) under the Securities Exchange Act of 1934).Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that as of December 31, 2017, the end of the period covered bythis Annual Report on Form 10K, we maintained effective disclosure controls and procedures.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a15(f) and 15d15(f) underthe Exchange Act.
