BUSINESS Overview We design, develop and sell exoskeleton technology that currently has applications in healthcare and industrial markets. Our wearable exoskeletons are worn over clothing and are mechanically controlled by a trained operator to augment human strength, endurance and mobility. Our exoskeleton technology serves multiple markets and can be used both by able-bodied users as well as by persons with physical disabilities. We have sold, rented or leased devices that (a) enable individuals with neurological conditions affecting gait (stroke and spinal cord injury) to rehabilitate and to walk again and (b) allow industrial workers to perform heavy duty work for extended periods. We believe the commercial opportunity for exoskeleton technology adoption is accelerating as a result of recent advancements in material technologies, electronic and electrical engineering, control technologies, and sensor and software development. Taken individually, many of these advancements have become ubiquitous in peoples’ everyday lives. We believe we have learned how to integrate these existing technologies and wrap the result around a human being efficiently, elegantly and safely, supported by an industry leading intellectual property portfolio. We further believe we can do so across a broad spectrum of applications, from persons with lower limb paralysis to able-bodied users. While we believe advancements in technology will continue driving commercial interest in and further development of exoskeleton systems, we also recognize that we are in the early stages of development of exoskeleton capabilities. In order to advance the commercialization of our exoskeleton technology, we intend to focus our efforts in 2018 on the following key initiatives: · Drive robotic exoskeleton rehabilitation to become the standard of care for both in-patient and out-patient rehabilitation for patients with · · · · · some form of lower limb paralysis or weakness. Expand our presence to select countries in Asia. Continue to introduce new features in rehabilitation for our Ekso GT, which could expand access to care to more patients, and for our EksoPulse Analytics, which aids in providing more personalized care in rehabilitation sessions. Continue patient enrollment in our company-sponsored randomized controlled trial Walking Improvement for SCI with Exoskeletons (“WISE”) Study and further add to the growing body of clinical evidence to support the use of Ekso GT for rehabilitation. Continue leveraging our commercial experience with the Ekso GT and our exoskeleton development work to develop an appropriate go- to-market strategy for our next generation medical devices for use outside of a rehabilitation setting. We are striving to bring to market devices that will be cost-effective, with the appropriate functionality and levels of independence for their use outside of a rehabilitation setting. Build upon our momentum in industrial markets, expanding on the commercial rollout of EksoZeroG for aerial work platforms and scaffolding to include the commercial rollout of EksoVest, an upper body exoskeleton that elevates and supports a worker's arms to assist them with tasks ranging from chest height to overhead while enabling freedom of motion. Rehabilitation Robotics Today, our focus is on rehabilitation robotics. We are leveraging our patented exoskeleton technology to develop and market products intended to enable patients with some form of lower limb paralysis to rehabilitate earlier and with better outcomes than the current standard of care. 4 Table of Contents Ekso GT Our current product, the Ekso GT, is a wearable bionic suit that allows our hospital and rehabilitation customers to provide in-patients and out-patients with spinal cord injury (“SCI”) and hemiplegia due to stroke the ability to stand and walk over ground with a full weight- bearing, reciprocal gait using a cane, crutches or a walker under the supervision of a physical therapist. Walking is achieved by a user shifting their body to activate sensors in the device which in turn initiate steps. Battery-powered motors drive the legs, detecting the deficient neuromuscular function and providing that level of assistance necessary for a user to complete their step. Users can expect to walk with aid from the device the first time they put on the Ekso GT exoskeleton (after passing an assessment). Physical therapists can transfer patients to or from their wheelchair and don or remove the Ekso GT in less than five minutes. The Ekso GT incorporates SmartAssist, our proprietary, adaptive or “smart” software that detects a user’s level of motor loss and dynamically provides 0-100% power to either side of the body. SmartAssist can promote a greater number of high-quality steps in a short time period and support the early re-learning of correct step patterns and weight shifts, potentially mitigating compensatory behaviors. SmartAssist also has allowed our customers to significantly expand the spectrum of patients that can potentially benefit from robotic rehabilitation. In addition, SmartAssist can aid in promoting early mobility by training patients (PreGait) to walk in an exoskeleton, which should expand access to care to more patients. SmartAssist also includes next generation Variable Assist technology that provides more freedom for healthcare providers to allow patients to power themselves (FreeGait) in the most appropriate ways possible. Lastly, SmartAssist includes QuickFit, a more rehabilitation friendly user-interface that should reduce potential data input / output errors. In December of 2017 we also launched in Europe the Ekso GT Functional Electrical Stimulation (FES) interface capability through a partnership with Hasomed GmbH, a developer of innovative products for neurological rehabilitation. FES is a technique that uses low energy electrical pulses to artificially generate body movements in individuals who have been paralyzed due to injury to the central nervous system. We believe the combination of exoskeleton technology with SmartAssist and FES gives clinicians the synergistic benefits of earlier mobility and muscle stimulations to provide rehabilitation to a broader spectrum of patients. Another important feature of our Ekso GT is its Ekso Pulse Analytics, a real-time data capture program. Ekso Pulse gathers and transmits statistics and device information during Ekso GT walking sessions. This information can be used to track patient progression and to monitor device utilization. The Ekso GT records data such as steps, speed, step size, and other settings along with all error logs and operating parameters. Data is sent securely to our servers where it is available for customers to view, filter, and export through a secure web portal. This feature enables more thorough patient care while reducing manual data entry. It also enables us to provide a higher level of service through early identification and thorough reporting of device errors, saving customers the time and expense of unnecessary on-site visits. The Ekso GT is used by customers in both in-patient and out-patient settings. Our customers believe that for patients with some motor ability intact (for example, after a stroke or an incomplete SCI), the Ekso GT exoskeleton offers unique benefits to help therapists teach proper step patterns and weight shifts, allowing patients potentially to mobilize earlier and ultimately to walk again. By allowing individuals to stand and walk in a full weight-bearing setting, early clinical evidence is also beginning to show that the Ekso exoskeleton may offer potential healthcare benefits (including for patients with complete SCI) such as reducing post-injury medical costs through reduction in secondary complications such as pressure sores, urinary tract infections, bowel problems, pneumonia and other respiratory issues, bone loss/osteoporosis, cardiovascular disease and psychological disorders. As of February 1, 2018, the Company had shipped over 275 Ekso GT units to close to 200 rehabilitation facilities or customers worldwide. The number of units utilized at a center varies from one to six, and is driven by the number of beds and rehabilitation sessions a hospital can offer and that hospital’s adoption of robotics within its rehabilitation protocols. 5 Table of Contents Market Overview The primary market for our Ekso GT is rehabilitation clinics with significant stroke and SCI populations. In the U.S. there are about 5.9 million stroke and SCI rehabilitation sessions conducted annually on about 680,000 stroke and SCI patients at approximately 16,900 facilities. Global estimates for stroke and SCI populations are more than double those in the U.S. Due to the chronic nature of the conditions resulting in lower limb impairment, we believe these diagnoses have an enormous clinical and economic impact on both people with the conditions and the healthcare system. According to the American Heart Association, in the U.S. there are approximately 795,000 strokes per year with approximately 7 million people living who have suffered from a stroke. Direct and indirect costs associated with those who have suffered a stroke total approximately $60 billion annually. Similarly, according to the National Spinal Cord Injury Statistical Center, in the U.S. there are approximately 12,500 incidences of SCI per year with approximately 275,000 people living with SCI. Direct and indirect costs associated with those who have suffered SCI total approximately $18.5 billion annually. While the market opportunity for robotic exoskeleton rehabilitation may be large, we also recognize that the path for medical devices to become standard of care is long and challenging. We believe our ability to accelerate adoption will also be based, in part, on our ability to build on our and our partners’ early efforts: (i) to expand clinical evidence and (ii) to drive toward standard of care. We are already seeing customers appreciate that one way for stroke patients at in-patient facilities to receive the recommended amount of rehabilitation per guidelines is by using an Ekso GT, the only device currently in the market that has the versatility to provide an over-ground gait training intervention that is task-specific, high intensity and allows for a margin of error, across the continuum of care. Clinical Evidence and Reimbursement Many of our early clinical customers have undertaken research to evaluate the use in rehabilitation of exoskeletons in general and our Ekso robotic exoskeleton in particular. Although these studies primarily have focused on feasibility and safety and have relied on small sample sizes, initial study findings have been favorable. In 2017, we learned of results for eleven clinical studies for SCI and four for stroke. One completed SCI study included nine Pan-European sites with 52 participants. One other study included 23 sub-acute and chronic stroke participants. Also, we have now enrolled ten sites for our company sponsored WISE (Walking Improvement for SCI with Exoskeletons) study. These sites, in turn, have enrolled over 20 patients. The primary endpoint of the WISE study seeks to demonstrate that a 12-week robotic gait training regimen can lead to a clinically meaningful improvement in independent walking speed. Secondary endpoints from the trial are examining economic factors such as number of physical therapists and staff required during training, the physical burden on physical therapists assisting and supervising during training, and the influence of factors that may modify the gait recovery. We intend to continue our work with rehabilitation centers and clinicians studying the benefits of robotic exoskeleton rehabilitation using the Ekso. We have also increased the number of centers of excellence to four, with the first European Center of Robotic Excellence established in northern Italy at Villa Beretta Centro di Riabilitazione coming on board. We believe that additional clinical evidence will help treating physicians to better understand the benefits of rehabilitation with the Ekso GT and will support our efforts with more industry collaboration toward achieving reimbursement for exoskeletons. We believe that reimbursement by the Centers for Medicare/Medicaid Services (“CMS”) and third-party insurers will play an important role in the long-term success of our efforts to drive commercial adoption of our Ekso GT and to make the Ekso GT a standard of care for rehabilitation for patients with some form of lower limb paralysis or weakness. In order to establish an appropriate robotic exoskeleton coding mechanism as well as gain coverage and payment by payers, the Company and its competitors must generate both clinical and economic evidence demonstrating the benefits of robotic exoskeletons. We believe that the investments we are making in clinical trials will assist in generating this evidence. Generally, reimbursement for professional services performed at the hospital in the out-patient rehabilitation setting is reported under separate billing codes issued by the American Medical Association (“AMA”) known as Current Procedural Terminology (“CPT”) codes. While existing Physical Therapy CPT codes provide modest reimbursement for the use of our technology in the out-patient rehabilitation setting, we are aware of no CPT code that specifically describes robotic exoskeletons. We may determine to pursue an application for a new CPT code. We have engaged the services of expert consultants with extensive experience in CPT coding, coverage and payment to assist us in our reimbursement strategy. 6 Table of Contents The European Union also requires a two-track approach to market penetration and subsequent coverage, requiring separate claims for purchasing the device and for requests for reimbursement. We are well represented in clinics run by German and Austrian accident insurers, with four out of 13 rehabilitation sites in Germany and three out of four rehabilitation sites in Austria. We also have a growing number of patients in Europe, who get reimbursement on a case-by-case decision covered by public and private health insurers for in-patient and out- patient treatment. The first paid out-patient trial with an accident insurer in collaboration with an out-patient rehabilitation center, where a patient trains twice a week, has also started in late 2017. This is a model we want to build upon in 2018. We will use these examples to integrate exoskeletal therapy in existing care pathways. In the United Kingdom, the National Institute for Health and Care Excellence (NICE), has selected us as the first exoskeleton company to produce a Medtech Innovation Briefing (MIB), which are designed to support National Health Services (NHS) and social care commissioners and staff who are considering using new medical devices and other medical or diagnostic technologies. The MIB highlighted the innovative aspect of our proprietary SmartAssist software, which differentiates the Ekso GT from other available exoskeletons. Current Sales and Marketing Efforts Our key marketing goal today is to achieve broad-based commercial adoption of our Ekso GT in the rehabilitation setting. We are focusing our go-to-market protocols and collateral on our three target audiences: medical administrators, medical directors/therapists and patients. Working closely with thought leaders, we will continue to build upon our early user-group exchanges, develop clinical education programs, and grow our medical advisory council. With the receipt of our clearance from the U.S. Food and Drug Administration (“FDA”) in April 2016, we introduced new strategies and tactics to increase awareness in our target audiences, including leveraging social media, public relations, tradeshows, marketing automation, and market development activities which will continue throughout 2018. There continues to be high market interest in expanding neurosciences service lines. As such, in 2018, our sales priorities are to effectively educate both clinical and executive stakeholders on the economic/clinical value of starting an Ekso GT Robotics Stroke and SCI Rehabilitation Program. In tandem, we will leverage our Ekso GT customer base to educate and mentor target strategic centers that specialize in Stroke and SCI rehabilitation. Geographically, the priorities have been North America (Canada, the U.S., and Mexico) and Europe, the Middle East, and Africa (“EMEA”). Beginning late 2017, we expanded our focus to include Asia-Pacific and initiated an effort to seek a strategic partnership for the sales and manufacture of the Company’s products in China. Currently, we utilize a direct sales force for the U.S., Canada, the United Kingdom, Spain and the German-speaking countries of Europe. We also have an expanding distributor network in EMEA and Central and South America. The sales and marketing team is principally based in the U.S. and Germany and is structured as follows: · One commercial leader for the Americas and one EMEA-based manager for our distributors; · U.S. and EMEA sales professionals that pursue new prospects and organizes demonstrations; · Clinical professionals/physical therapists that provide peer-to-peer demonstrations and trainings; · Marketing professionals, graphic designers, and consultants to build awareness and generate demand; · Ambassadors with spinal cord injury that provide demonstrations and personal experiences. The sales cycle for the Ekso GT averages approximately eight to 12 months for a first device and two to four months for subsequent devices. Our typical sale is the Ekso GT complete package, which includes the device and all relevant components, two sets of batteries for continuous run-time, training through two levels of certification, and SmartAssist software. Customers also typically purchase Ekso Care, which is our one- to four-year after sales service package. After Sales Service We provide service for the Ekso GT at our facility in Richmond, California or in Germany for our European customers. When maintenance or service is required, a customer schedules service by contacting us and we then arrange for the appropriate service, depending on the level of Ekso Care for which a customer has contracted. In some cases we may decide it’s appropriate to have an Ekso field technician fly to the customer site to service the device. The Ekso GT is designed with Ekso Pulse, which allows us to diagnose many customer service issues remotely. 7 Table of Contents Manufacturing and Supply Chain We produce the Ekso GT at our facilities in Richmond, California. We currently run one line for one shift per day and believe we have the capacity to eventually run up to four lines for two shifts per day should we deem it appropriate. The Ekso GT uses over 700 purchased parts, which we source globally from over 70 suppliers. Whenever possible, we seek to secure dual source suppliers for our components. Our commitment to the philosophy of continuous improvement has continued to increase product performance and reliability over the past year. As a result, we expect our cost of field service will continue to decline over the next 12 months. Home Mobility The dynamics and product requirements of the home mobility market are different from those of the clinic. While we believe the home mobility market opportunity is sizable, it will only be served once next generation technology is brought to market that is cost effective for individuals because reimbursement is available and has a level of functionality that enables independent mobilization. Home mobility exoskeletons should be fitted to a specific patient and designed for all-day use. In addition, we believe they must be easily transportable, and have improved dynamic stability, user interfaces, and terrain navigation to allow the home users to confidently walk through their daily life with little or no assistance. As we continue to develop our commercial experience with a medical exoskeleton in the rehabilitation setting, coupled with recent research and development advancements in exoskeleton and related technologies, we are now investing resources to design such a commercial product and to develop our go-to-market approach for mass adoption of home mobility devices. We are also collaborating with world-class academic and commercial institutions to refine our technology and to apply the latest technological breakthroughs to the advancement of human ambulation. In addition to implementing the technological changes necessary in an exoskeleton designed for the home mobility market, we are in parallel working with payers and ensuring our (and where possible, our partners’) trials are and will be generating clinical and economic evidence on the benefits of exoskeletons for home mobility use. Lastly, the go-to-market strategy will likely be quite different than our current sales and marketing approach for the rehabilitation markets. Critical to our success will be implementing such a strategy, possibly with partner(s), which is sustainable to address the potential size of the market. Able-Bodied Industrial Applications (EksoWorks) In December 2014, we introduced our first prototype of an unpowered exoskeleton intended for industrial applications. During 2015, we began investing resources to support requests for prototype demonstrations and in-depth field-testing in real world conditions with advanced prototypes. Our feedback indicates a growing imperative among construction and manufacturing companies to drive adoption of improved safety and health practices. Furthermore, based on initial customer field-testing and market research, we believe industrial exoskeletons have the potential to help prevent workforce injuries, improve productivity and over time reduce workmen’s compensation and related costs. According to a Bureau of Labor Statistics Report (2012), direct costs related to injuries associated with overexertion in the workplace total over $21.1 billion per year. In addition, human augmentation technology is being viewed by senior managers of companies that have participated in field-testing as an opportunity to extend the careers of experienced and skilled workers while also changing the work environment to attract future workers to these careers. In 2016, we introduced a new product innovation for aerial work platforms (AWP) and scaffolding, the EksoZeroG, which is intended to significantly improve workforce productivity while dramatically reducing workplace related injuries in order to keep workers healthy, strong, and safe. EksoZeroG is a mobile arm mount that makes heavy tools feel weightless and enables workers to be more productive and safer. In 2017, we introduced a second commercial product for industrial applications, the EksoVest, an upper body exoskeleton that elevates and supports a worker's arms to assist them with tasks ranging from chest height to overhead. It is lightweight and low profile, making it comfortable to wear in all conditions while enabling freedom of motion. The goal is for workplaces with the EksoVest to experience fewer on-site injuries while tasks are completed faster and with higher quality results, for workers to stay healthier and experience increased stamina, and for companies to gain greater productivity in factories and on construction sites. 8 Table of Contents We believe there is additional mid-to-long-term potential in the industrial markets, and accordingly, we will continue our development efforts to expand our EksoWorks product offerings. Ekso Labs Ekso Labs, our engineering services division, has historically been focused on technology development and future applications. It is an exoskeleton laboratory that integrates emerging technologies into new product applications and expands on it for our partners. To date, the majority of our Ekso Labs revenue has been in the form of research grants from government organizations including United States Special Operations Command, the Defense Advanced Research Projects Agency, the National Institute of Health and the National Science Foundation. These projects fund research and development on new exoskeleton systems, providing us with new intellectual property and exoskeleton designs that have the potential for commercialization. In addition to furthering exoskeleton technology for our current medical applications, Ekso Labs’ research and development work may have potential use in future, able-bodied models of the Ekso human exoskeleton. Many of the research projects funded by grants are focused on researching future medical applications and capabilities not yet ready for commercial development. Other projects, often funded by commercial partners or the U.S. military, focus on able-bodied human exoskeleton applications. In early 2016 we made the strategic decision to shift our engineering resources away from the billable engineering services of Ekso Labs and to our internal development efforts both for our next generation home/wellness device and for able-bodied industrial offerings. As a consequence, in the near term we expect Ekso Labs to play a lesser role than historically. Financial Information About Segments and Geographic Areas We have three reportable segments: Medical Devices, Industrial Sales, and Engineering Services. The segment and geographic information required herein is contained in Note 17 in the notes to our consolidated financial statements, which appear under Item 8 in this Annual Report on Form 10-K, under the caption Segment Disclosures. Intellectual Property The Company has established an extensive intellectual property portfolio that includes various U.S. patents and patent applications. The table below provides a summary of U.S. patents by issuing status and ownership status. License Status Licensed to the Company Exclusively licensed to the Company Co-owned with Regents of the University of California, exclusively licensed to the Company Co-owned with the Regents of the University of California Sole ownership by the Company Total: 67 9 Issued Patents 13 6 4 3 7 33 Issuing Status Pending Applications 2 - Provisional Applications - - 30 32 - - - - 2 2 Table of Contents Pending applications mean a complete application has been filed with the applicable patent authority and additional action is pending. Provisional applications mean that we have filed a short form application to establish an early filing date in anticipation of completion and submission of a complete application in the future. Many of these applications have also been filed internationally as appropriate for their respective subject matter. As of January 4, 2018, 127 applications have issued or have been allowed as patents internationally. All told, our patent portfolio contains 263 cases that have issued or are in prosecution in 23 countries. Our patent portfolio includes product and method type claims, since the devices that we produce and the processes performed by those devices are patentable. Our patents encompass technologies relevant to our devices, including medical exoskeletons, commercial exoskeletons, actuators, and strength-enhancing exoskeletons. The earliest priority date of the portfolio reaches back to 2003, and new applications continue to be filed. Licensors include the Regents of the University of California (“RUC”) and Garrett Brown (as a result of our acquisition of technology of Equipois). The license with RUC consists of two agreements and one amendment covering ten patent cases exclusively licensed to the Company, nine of which have issued and one of which remains in prosecution (the “RUC License Agreements”). Inventions covered by a further three patent applications are co-owned by the Company and RUC, with no license agreement between the Company and RUC. As a result, RUC may license its rights in these patents to a third party. With respect to two of these co-owned patent applications, RUC has licensed their rights in the U.S. to an unrelated third party. The third patent application will need to be fully prosecuted before it can be determined which claims are exclusive to us (through a previous license) and which claims RUC may license to other entities. Pursuant to the RUC License Agreements, we initially paid RUC consideration consisting of $5,000 in cash and 310,400 common shares of Ekso Bionics, and are also committed to pay a 1% royalty on sales, including sales generated by sublicenses. In addition, the RUC License Agreements call for minimum annual payments of $50,000. We do not pay royalties to RUC on products sold or to be resold to the U.S. government. In some cases, as a result of government funding we receive, the patents have a government use license, granting the U.S. government a non-exclusive, non-transferable, irrevocable, paid-up license for use of the inventions for or on behalf of the U.S. government, as is typical in the case of government sponsored research. In connection with our acquisition of assets of Equipois, we assumed the rights and obligations of Equipois under a license agreement with Garrett Brown, the developer of certain intellectual property related to mechanical balance and support arm technologies, which grants us an exclusive license with respect to the technology and patent rights for certain fields of use. Pursuant to the terms of the license agreement, we will be required to pay Mr. Brown a single-digit royalty on net receipts, subject to a $50,000 annual minimum royalty requirement. Intellectual Property Out-Licensing We believe that the breadth of the coverage across various bionic systems and technologies, together with our freedom to grant sub-licenses under the RUC License Agreements gives us the potential to generate licensing revenue in fields outside our present areas of commercialization. Since 2009, we have generated approximately $1.6 million in such licensing revenue from our two licensees: Lockheed Martin Corporation (“Lockheed”) and OttoBock Healthcare Product GmbH (“OttoBock”). The Company receives revenue pursuant to a Government Field Cross License Agreement dated as of July 1, 2013 between Ekso Bionics, Inc. and Lockheed and a Cross License Agreement dated as of July 1, 2013 between Ekso Bionics, Inc. and Lockheed, and previously pursuant to a License Agreement dated January 8, 2009, which was terminated effective as of July 1, 2013. Pursuant to these agreements, the Company has licensed to Lockheed certain rights with respect to its anthropomorphic exoskeleton technology for which Lockheed is obligated to pay Ekso Bionics, Inc. a royalty on sales of products incorporating such technology. Royalty fees from Lockheed were either de minimus or nil for the years ended December 31, 2017, 2016, and 2015, respectively. 10 Table of Contents With respect to OttoBock, the Company received exclusivity payments pursuant to the License and Services Agreement dated October 27, 2014. The License and Services Agreement grants OttoBock exclusive rights in order to develop a semi-active prosthetic knee prototype for use in medical prosthetics and provides that OttoBock will pay the Company a royalty based on sales by OttoBock of products incorporating the licensed technology. Royalty fees from OttoBock were $150,000, $100,000 and $100,000 for the years ended December 31, 2017, 2016, and 2015, respectively. Competition The medical technology and industrial robotics industries are characterized by intense competition and rapid technological change. We believe a number of other companies are developing competitive technology and devices for both the able-bodied and medical fields of use and many of these competitors have significantly more financial and other resources than we possess. In the medical field, we face competition from companies that are focused on technology for rehabilitation of patients suffering from stroke and related neurological disabilities as well as from companies that are focused on SCI. In stroke, Cyberdyne has developed ambulatory exoskeletons with a current commercial focus in Japan and Germany, while Hocoma, AlterG, Aretech and Reha Technology are selling treadmill-based gait therapies. In SCI, ReWalk Robotics and Parker Hannafin sell ambulatory exoskeletons. Other companies who have announced plans to commercialize robotic exoskeletons include: Bionik Laboratories and SuitX. Technologies developed by competitors in the areas of stroke rehabilitation and SCI represent therapeutic interventions with utility at varying points of the continuum of care. Clinically, the Ekso GT is unique in its broad ability to mobilize pre- or even non-ambulatory patients using a full weight bearing, over ground, task-based platform. From a practice management perspective, the Ekso GT is less expensive than many other systems, has a smaller footprint, the ability to move around the hospital, and uses standard power requirements that make it easy to integrate into existing infrastructure. Other over-ground exoskeletons were initially designed for an individual to achieve ambulation reliant on the device. By contrast, the Ekso GT’s design accommodates patients with complete paraplegia and additionally includes features that are optimized to assist therapists in helping patients with some motor ability learn to walk again in a clinical setting, treating several patients and indications in a single day. Notwithstanding the foregoing, the most pressing challenges we face are not necessarily competitive technologies, but rather achieving rapid market awareness and adoption of this emerging technology while acclimating prospects to a fundamentally new paradigm in neuro- rehabilitation and mobility. In addition, it may be difficult for the rehabilitation department of a hospital or clinic to secure the funds for acquisition of an Ekso device in an environment where capital expenditures of this magnitude are not commonly incurred by those rehabilitation departments. In the able-bodied field, Lockheed Martin, Raytheon, BAE Systems, Panasonic, Honda, Daewoo, Noonee, Revision Military and Cyberdyne – among others - are each developing some form of exoskeleton for military and/or industrial applications. The field of robotic exoskeleton technology remains in its infancy. As this field develops, we believe we will face increased competition on the basis of product features, clinical outcomes, price, services and other factors. Our competitive position will depend on multiple, complex factors, including our ability to achieve market acceptance for our products, develop new products, implement production and marketing plans, secure regulatory approvals for products under development and protect our intellectual property. In some instances, competitors may also offer, or may attempt to develop, alternative therapies for disease states that may be delivered without a medical device. Research and Development The Company engages in research and development activities in an effort to enhance the effectiveness, ease of use, safety and reliability of our commercial exoskeletons and to expand their applications. The Company’s research and development expenditures were $9.5 million, $8.9 million and $6.5 million in 2017, 2016 and 2015, respectively. As part of our engineering services (also known as Ekso Labs), we benefited from additional research and development expenditures of $0.6 million and $3.6 million in 2016 and 2015, respectively, and a de minimus amount in 2017. These are expenditures funded by grants, collaboration partners, or engineering services customers for whom we perform research and development work on human exoskeletons and related technologies. Funding has come from such third parties as Lockheed (approximately $6 million since 2008 for the development of the Human Universal Load Carrier (“HULC”)), the U.S. National Science Foundation, the National Institute of Health, the U.S. Defense Advanced Research Projects Agency (“DARPA”), U.S. Special Operations Command (“SOCOM”) and the U.S. Department of Defense. 11 Table of Contents Governmental Regulation and Product Approval U.S. Regulation The U.S. government regulates the medical device industry through various agencies, including but not limited to, the FDA, which administers the Federal Food, Drug and Cosmetic Act (“FDCA”). The design, testing, manufacturing, storage, labeling, distribution, advertising, and marketing of medical devices are subject to extensive regulation by federal, state, and local governmental authorities in the United States, including the FDA, and by similar agencies in other countries. Any medical device product that we develop must receive all requisite regulatory approvals or clearances, as the case may be, before it may be marketed in a particular country. Device Development, Marketing Clearance and Approval. The FDA classifies medical devices into one of three classes (Class I, II or III) based on the degree of risk the FDA determines to be associated with a device and the extent of control deemed necessary to ensure the device’s safety and effectiveness. Devices requiring fewer controls because they are deemed to pose lower risk are placed in Class I or II. Class I devices are deemed to pose the least risk and are subject only to general controls applicable to all devices, such as requirements for device labeling, premarket notification, and adherence to the FDA’s current good manufacturing practice requirements, as reflected in its Quality System Regulation (“QSR”). Class II devices are intermediate risk devices that are subject to general controls and may also be subject to special controls such as performance standards, product-specific guidance documents, special labeling requirements, patient registries or post-market surveillance. Class III devices are those for which insufficient information exists to assure safety and effectiveness solely through general or special controls, and include life-sustaining, life-supporting, or implantable devices, and devices not “substantially equivalent” to a device that is already legally marketed. Most Class I devices, and some Class II devices are exempted by regulation from the 510(k) clearance requirement and can be marketed without prior authorization from FDA. Class I and Class II devices that have not been so exempted are eligible for marketing through the 510(k) clearance pathway. By contrast, devices placed in Class III generally require premarket approval, or PMA, prior to commercial marketing. To obtain 510(k) clearance for a medical device, an applicant must submit a premarket notification application to the FDA demonstrating that the device is “substantially equivalent” to a predicate device, which is typically a Class II device that is legally marketed in the United States. A device is substantially equivalent to a predicate device if it has the same intended use and (i) the same technological characteristics, or (ii) has different technological characteristics and the information submitted demonstrates that the device is as safe and effective as a legally marketed device and does not raise different questions of safety or effectiveness. A showing of substantial equivalence sometimes, but not always, requires clinical data. Generally, the 510(k) clearance process can exceed 90 days and may extend to a year or more. After a device has received 510(k) clearance for a specific intended use, any modification that could significantly affect its safety or effectiveness, such as a significant change in the design, materials, method of manufacture or intended use, will require a new 510(k) clearance or (if the device as modified is not substantially equivalent to a legally marketed predicate device) PMA. While the determination as to whether new authorization is needed is initially left to the manufacturer, the FDA may review this determination and evaluate the regulatory status of the modified product at any time and may request the manufacturer to cease marketing and recall the modified device until 510(k) clearance or PMA is obtained. The manufacturer may also be subject to significant regulatory fines or penalties. The second, more comprehensive, approval process applies to a new device that is not substantially equivalent to a predicate device or that is to be used in supporting or sustaining life or preventing impairment. These devices are normally Class III devices requiring PMA. The FDA will approve the PMA application if it finds there is reasonable assurance that the device is safe and effective for its intended use. The PMA process takes substantially longer than the 510(k) process, approximately one to two years or more. 12 Table of Contents In some instances the FDA may find that a device is new and not substantially equivalent to a predicate device but is also not a high risk device as is generally the case with Class III PMA devices. In these instances, the FDA may allow a device to be reclassified from Class III to Class I or II. The de novo reclassification option is an alternate pathway to classify novel devices of low to moderate risk that had automatically been placed in Class III after receiving a “not substantially equivalent” (NSE) determination in response to a 510(k) notification. The FDCA has also been amended to allow a sponsor to submit a de novo reclassification request to the FDA for novel low to moderate risk devices without first being required to submit a 510(k) application. These types of applications are referred to as “Evaluation of Automatic Class III Designation” or “de novo.” In instances where a device is deemed not substantially equivalent to a Class II predicate device, the candidate device may be filed as a de novo application which may lead to delays in regulatory decisions by the FDA. FDA review of a de novo application may lead the FDA to identify the device as either a Class I or II device and subject to or exempt from 510(k) premarket notification. Clinical trials are generally required to support a PMA or de novo reclassification application and are sometimes required for 510(k) clearance. Clinical trials generally require an investigational device exemption application, or IDE, approved in advance by the FDA for a specified number of patients and study sites, unless the product is deemed a non-significant risk device eligible for more abbreviated IDE requirements. Clinical trials are subject to extensive monitoring, recordkeeping and reporting requirements. Clinical trials must be conducted under the oversight of an institutional review board (IRB), for the relevant clinical trial sites and must comply with FDA regulations, including but not limited to those relating to good clinical practices. To conduct a clinical trial, we also are required to obtain the patients' informed consent in form and substance that complies with both FDA requirements and state and federal privacy and human subject protection regulations. We, the FDA or the IRB could suspend a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits. Even if a trial is completed, the results of clinical testing may not adequately demonstrate the safety and efficacy of the device or may otherwise not be sufficient to obtain FDA approval to market the product in the U.S. To date, the Ekso device has been the subject of several clinical studies, some sponsored by the Company, as well as non-Ekso- sponsored independent studies conducted by rehabilitation institutions. In addition, we are currently conducting several studies to investigate additional indications for use for the Ekso device, as well as to evaluate clinical and non-clinical outcomes of using the Ekso device. We believe that the Company’s robotic exoskeleton has been appropriately marketed as a Class I 510(k) exempt Powered Exercise Equipment device since it was first sold in the United States in February 2012. On June 26, 2014, the FDA announced the creation of a new product classification for Powered Exoskeleton devices. On October 21, 2014, the FDA published the summary for the new Powered Exoskeleton classification and designated it as being Class II, which requires the clearance of a 510(k) notice. On October 21, 2014, concurrent with the FDA’s publication of the reclassification of Powered Exoskeleton devices, the FDA issued the Company an “Untitled Letter” which informed the Company in writing of the agency’s belief that this new product classification applied to our Ekso GT device. On December 24, 2014, the Company filed a 510(k) notice for the Ekso robotic exoskeleton, which was accepted by the FDA for substantive review on July 29, 2015. On April 4, 2016, we received clearance from the FDA to market our Ekso GT robotic exoskeleton for use in the treatment of individuals with hemiplegia due to stroke, individuals with spinal cord injuries at levels T4 to L5, and individuals with spinal cord injuries at levels of T3 to C7 (ASIA D), in accordance with the device’s labeling. On July 19, 2016, we received clearance from the FDA to expand/clarify the indications and labeling to expressly include individuals with hemiplegia due to stroke who have upper extremity function of at least 4/5 in only one arm. Our prior cleared indications for use statement required that individuals with hemiplegia due to stroke have upper extremity function of at least 4/5 in both arms. Pervasive and continuing regulation. After a device is placed on the market, numerous regulatory requirements apply. These include: 13 Table of Contents product listing and establishment registration, which helps facilitate FDA inspections and other regulatory action; · · Quality System Regulation, or QSR, which requires manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all aspects of the manufacturing process; labeling regulations and FDA prohibitions against the promotion of products for un-cleared, unapproved or off-label use or indication; 510(k) clearance of product modifications that could significantly affect safety or efficacy or that would constitute a major change in intended use of one of our cleared devices; · · · medical device reporting regulations, which require that manufacturers comply with FDA requirements to report if their device may have caused or contributed to a death or serious injury, or has malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction of the device or a similar device were to recur; post-approval restrictions or conditions, including post-approval study commitments; post-market surveillance regulations, which apply when necessary to protect the public health or to provide additional safety and effectiveness data for the device; the FDA's recall authority, whereby it can ask, or under certain conditions order, device manufacturers to recall from the market a product that is in violation of governing laws and regulations; regulations pertaining to voluntary recalls; and notices provision regarding corrections or removals. · · · · · Advertising and promotion of medical devices, in addition to being regulated by the FDA, are also regulated by the Federal Trade Commission and by state regulatory and enforcement authorities. Recently, promotional activities for FDA-regulated products of other companies have been the subject of enforcement action brought under healthcare reimbursement laws and consumer protection statutes. In addition, under the federal Lanham Act and similar state laws, competitors and others can initiate litigation relating to advertising claims. If the FDA determines that our promotional materials or training constitutes promotion of an un-cleared or unapproved use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, our reputation could be damaged and adoption of the products would be impaired. The FDA has broad post-market and regulatory enforcement powers. We are subject to unannounced inspections by the FDA to determine our compliance with the QSR and other regulations. From September 2, 2015 to September 11, 2015, the Division of Bioresearch Monitoring of the FDA’s Office of Compliance conducted an inspection of the Company’s facility in Richmond, California. At the conclusion of the inspection, the FDA issued a Form FDA 483 with observations pertaining to informed consent requirements, reporting of events to FDA, and records maintenance. These observations are inspectional and do not represent a final FDA determination of non-compliance. On October 2, 2015, we responded to the FDA describing the corrective and preventive actions that we have implemented and continue to implement to address the FDA’s observations. Due to the nature of the findings, we do not expect that the Form FDA 483 will result in a warning letter or other action that could interfere with our operations. On March 30, 2016, the FDA accepted our corrective actions for the Form 483 observations that were generated during the FDA inspection. Since January 1, 2017, we have been informed of two adverse events with respect to our Ekso GT devices that are reportable pursuant to the FDA’s medical device reporting, or MDR, regulations. In the first report, it was determined that the device did not cause or contribute to the injury. An evaluation of the second event determined that the device did not malfunction and the patient injury was due to an incorrect setting by the physical therapist. In each case we have filed the required adverse event reports with the FDA. Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA or other regulatory authorities, which may result in sanctions including, but not limited to: 14 Table of Contents untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties; unanticipated expenditures to address or defend such actions customer notifications for repair, replacement, refunds; recall, detention or seizure of our products; operating restrictions or partial suspension or total shutdown of production; refusing or delaying our requests for 510(k) clearance or premarket approval of new products or modified products; operating restrictions; · · · · · · · · withdrawing 510(k) clearances that have already been granted; · · refusal to grant export approval for our products; or criminal prosecution. Foreign Regulation In addition to regulations in the U.S., we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our products in foreign countries. Whether or not the Company obtains FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign countries before the Company can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country. The policies of the FDA and foreign regulatory authorities may change and additional government regulations may be enacted which could prevent or delay regulatory approval of our products and could also increase the cost of regulatory compliance. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the U.S. or abroad. Employees As of December 31, 2017, we had 92 employees, including 89 full time employees and three part-time employees. Nine employees reside in Europe. None of our employees are covered by a collective bargaining agreement and we consider our relationship with our employees to be good. Corporate Information We were incorporated as PN Med Group Inc. in Nevada on January 30, 2012. Prior to the Merger and Split-Off (each as defined below), our business was to distribute medical supplies and equipment in Chile. On January 15, 2014, our wholly-owned subsidiary, Ekso Acquisition Corp., a corporation formed in the State of Delaware on January 3, 2014 merged with and into Ekso Bionics, Inc., a corporation incorporated in the State of Delaware on January 19, 2005. Ekso Bionics was the surviving corporation in the Merger and became our wholly-owned subsidiary. All of the outstanding Ekso Bionics stock was converted into shares of our common stock. In connection with the Merger and pursuant to a split-off agreement and general release, we transferred our pre-Merger assets and liabilities to our pre-Merger majority stockholders, in exchange for the surrender by them and cancellation of 2,497,586 shares of our common stock (the “Split-Off”), after adjusting to give effect to the 1-for-7 reverse stock split, discussed in Note 13 in the notes to our consolidated financial statements, which appear under Item 8 in this Annual Report on Form 10-K, under the caption Capitalization and Equity Structure – Reverse Stock Split. As a result of the Merger and Split-Off, we discontinued our pre-Merger business and acquired the business of Ekso Bionics, and have continued the existing business operations of Ekso Bionics as a publicly-traded company under the name Ekso Bionics Holdings, Inc. Our principal executive office is located at 1414 Harbour Way South, Suite 1201, Richmond, California, and our telephone number is (510) 984-1761. We make available free of charge on or through our website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports as soon as reasonably practicable after they are electronically filed with, or furnished to, the SEC. Our internet address is www.eksobionics.com. This website address is intended to be an inactive, textual reference only; none of the material on this website is part of this Report. Copies of our annual reports on Form 10-K will be furnished without charge to any person who submits a written request directed to the attention of our Secretary, at our offices located at 1414 Harbour Way South, Suite 1201, Richmond, California, 94804. The SEC maintains an internet site (http://www.sec.gov) that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. 15 Table of Contents Item 1A. RISK FACTORS An investment in our securities is highly speculative and involves a high degree of risk. We face a variety of risks that may affect our operations or financial results and many of those risks are driven by factors that we cannot control or predict. Before investing in our securities you should carefully consider the following risks, together with the financial and other information contained in this prospectus. If any of the following risks actually occurs, our business, prospects, financial condition and results of operations could be materially adversely affected. In that case, the trading price of our common stock would likely decline and investors may lose all or a part of their investment. This report contains certain statements relating to future events or the future financial performance of our Company. Readers are cautioned that such statements are only predictions and involve risks and uncertainties, and that actual events or results may differ materially. In evaluating such statements, readers should specifically consider the various factors identified in this report, including the matters set forth below, which could cause actual results to differ materially from those indicated by such forward-looking statements. The risks described below do not purport to be all the risks to which the Company could be exposed. This section is a summary of certain risks and is not set out in any particular order of priority. They are the risks that we presently believe are material to the operations of the Company. Additional risks of which we are not presently aware or which we presently deem immaterial may also impair the Company’s business, financial condition or results of operations. Risks Related to our Business and the Industry in Which We Operate We have a limited operating history upon which investors can evaluate our future prospects. Although we were incorporated in 2005, we did not sell our first Ekso medical device until 2012 and did not sell our first industrial unit until 2016. Therefore, we have limited operating history upon which an evaluation of our business plan or performance and prospects can be made. Our business and prospects must be considered in light of the potential problems, delays, uncertainties and complications encountered in connection with a newly established business and creating a new industry. The risks include, but are not limited to, the possibility that we will not be able to develop functional and scalable products and services, or that although functional and scalable, our products and services will not be economical to market; that our competitors hold proprietary rights that preclude us from marketing such products; that our competitors market a superior or equivalent product; that we are not able to upgrade and enhance our technologies and products to accommodate new features and expanded service offerings; or that we fail to receive necessary regulatory clearances for our products. To successfully introduce and market our products at a profit, we must establish brand name recognition and competitive advantages for our products. There are no assurances that we can successfully address these challenges. If we are unsuccessful, we and our business, financial condition and operating results could be materially and adversely affected. Given the limited operating history, management has little basis on which to forecast future demand for our products from our existing customer base, much less new customers. Our current and future expense levels are based largely on estimates of planned operations and future revenues rather than experience. It is difficult to accurately forecast future revenues because our business is new and our market has not been developed. If our forecasts prove incorrect, our business, operating results and financial condition will be materially and adversely affected. Moreover, we may be unable to adjust our spending in a timely manner to compensate for any unanticipated reduction in revenue. As a result, any significant reduction in revenues would immediately and adversely affect our business, financial condition and operating results. The industries in which we operate are highly competitive and subject to rapid technological change. If our competitors are better able to develop and market products that are safer, more effective, less costly, easier to use, or are otherwise more attractive, we may be unable to compete effectively with other companies. The medical technology and industrial robotics industries are characterized by intense competition and rapid technological change, and we will face competition on the basis of product features, clinical outcomes, price, services and other factors. Competitors may include large medical device and other companies, some of which have significantly greater financial and marketing resources than we do, and firms that are more specialized than we are with respect to particular markets. Our competition may respond more quickly to new or emerging technologies, undertake more extensive marketing campaigns, have greater financial, marketing and other resources than we do or may be more successful in attracting potential customers, employees and strategic partners. 16 Table of Contents Our competitive position will depend on multiple, complex factors, including our ability to achieve market acceptance for our products, develop new products, implement production and marketing plans, secure regulatory approvals for products under development and protect our intellectual property. Competitors may offer, or may attempt to develop, more efficacious, safer, cheaper, or more convenient alternatives to our products, including alternatives that could make the need for robotic exoskeletons obsolete. The development of new or improved products, processes or technologies by other companies may render our products or proposed products obsolete or less competitive. The entry into the market of manufacturers located in low-cost manufacturing locations may also create pricing pressure, particularly in developing markets. Our future success depends, among other things, upon our ability to compete effectively against current technology, as well as to respond effectively to technological advances, and upon our ability to successfully implement our marketing strategies and execute our research and development plan. Our products or exoskeletons generally may not be accepted in the market. We cannot be certain that our current products or any other products we may develop or market will achieve or maintain market acceptance. Market acceptance of our products depends on many factors, including our ability to convince key opinion leaders to provide recommendations regarding our products, convince distributors and customers that our technology is an attractive alternative to other technologies, convince health insurers and other third party payers to cover and provide adequate payments for any products that are used for medical or therapeutic purposes, demonstrate that our products are reliable and supported by us in the field, supply and service sufficient quantities of products directly or through marketing alliances, and price products competitively in light of the current macroeconomic environment, which, particularly in the case of the medical device industry, is becoming increasingly price sensitive. In addition, the market for medical and industrial exoskeletons is new and unproven. We cannot be certain that the market for robotic exoskeletons will continue to develop, or that robotic exoskeletons for medical or industrial use will achieve market acceptance. If the exoskeleton market fails to develop, or develops more slowly than we anticipate, we and our business, financial condition and operating results could be materially and adversely affected. Protecting our patent and other proprietary rights can be costly, and we may not be able to attain, defend or maintain such rights, which could harm our business. Our long-term success largely depends on our ability to market technologically competitive products. Failure to protect or to obtain, maintain or extend adequate patent and other intellectual property rights could materially adversely impact our competitive advantage and impair our business. Our issued patents may not be sufficient to protect our intellectual property and our patent applications may not result in issued patents. Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner or may challenge the validity of our patents. Our attempts to prevent third parties from circumventing our intellectual property and other rights ultimately may be unsuccessful. We may also fail to take the required actions or pay the necessary fees to maintain any of our patents that issue. Furthermore, we have not filed applications for all of our patents internationally and may not be able to prevent third parties from using our proprietary technologies or may lose access to technologies critical to our products in other countries. These include, in some cases, countries in which we are currently selling products and countries in which we intend to sell products in the future. Intellectual property litigation and infringement claims could cause us to incur significant expenses or prevent us from selling certain of our products. 17 Table of Contents The industries in which we operate, including, in particular, the medical device industry, are characterized by extensive intellectual property litigation and, from time to time, we might be the subject of claims by third parties of potential infringement or misappropriation. Regardless of outcome, such claims are expensive to defend and divert the time and effort of our management and operating personnel from other business issues. A successful claim or claims of patent or other intellectual property infringement against us could result in our payment of significant monetary damages and/or royalty payments or negatively impact our ability to sell current or future products in the affected category and could have a material adverse effect on our business, cash flows, financial condition or results of operations. Some of the patents and patent applications in the intellectual property portfolio are not within our complete control, which could reduce the value of such patents. Some of our U.S. patents and patent applications (which have associated international patents and applications) are co-owned by the Regents of the University of California Berkeley. The Regents of the University of California Berkeley has licensed its rights under many of these patent applications to us, but we do not have a license to their rights under three of these patent applications. With respect to two of these co-owned patent applications, the Regents of the University of California Berkeley have licensed their rights in the U.S. to an unrelated third party. The third patent application will need to be fully prosecuted before it can be determined which claims are exclusive to us (through a previous license) and which claims the Regents of the University of California Berkeley may license to other entities. In addition, in connection with our acquisition of certain assets from Equipois, we assumed the rights and obligations of Equipois with respect to certain patents and patent applications under an in-license of intellectual property from a third party and subject to an out-license of that intellectual property to an unrelated third party for use in a particular field. We do not have complete control over the prosecution of these patent applications. In addition, the license of patent rights under these patents to third parties could reduce the value of our patent portfolio and limit any income or license fees that we might receive if we were to attempt to transfer or license our rights under any of our co-owned or licensed patents. If we fail to obtain or maintain necessary regulatory clearances or approvals for our medical device products, or if clearances or approvals for future products or modifications to existing products are delayed or not issued, our commercial operations would be harmed. The Ekso GT is a medical device that is subject to extensive regulation by the FDA, the European Union and other governmental authorities both inside and outside of the United States. These agencies enforce laws and regulations that govern the development, testing, manufacturing, labeling, advertising, marketing and distribution, and market surveillance of our medical products. Our failure to comply with these complex laws and regulations could have a material adverse effect on our business, results of operations, financial condition and cash flows. In the United States, before we can market a new medical device, or a new use of, new claim for or significant modification to an existing product, we must first receive either clearance under Section 510(k) of the FDCA or approval of a premarket approval, or PMA, application from the FDA, unless an exemption applies. Both the PMA and the 510(k) clearance process can be expensive, lengthy and uncertain. The FDA’s 510(k) clearance process may take anywhere from several months to over a year. The process of obtaining a PMA is much more costly and uncertain than the 510(k) clearance process and generally takes from one to three years, or even longer, from the time the application is filed with the FDA. In addition, PMA generally requires the performance of one or more clinical trials. The FDA also has substantial discretion in the medical device review process. Despite the time, effort and cost, we cannot assure you that any particular device will be approved or cleared by the FDA. Any delay or failure to obtain necessary regulatory approvals could harm our business. Failure can occur at any stage, and we could encounter problems that cause us to repeat or perform additional development, standardized testing, pre-clinical studies and clinical trials. Any delay or failure to obtain necessary regulatory approvals could harm or business. The FDA or other non-U.S. regulatory authorities can delay, limit or deny clearance or approval of a medical device candidate for many reasons, including: 18 Table of Contents • • • • • a medical device candidate may not be deemed to be substantially equivalent to a device lawfully marketed either as a grandfathered device or one that was cleared through the 510(k) premarket notification process; a medical device candidate may not be deemed to be in conformance with applicable standards and regulations; FDA or other regulatory officials may not find the data from pre-clinical studies and clinical trials or other product testing date to be sufficient; other non-U.S. regulatory authorities may not approve our processes or facilities or those of any of our third-party manufacturers, thereby restricting export; or the FDA or other non-U.S. regulatory authorities may change clearance or approval policies or adopt new regulations. Even after regulatory clearance or approval has been granted, a cleared or approved product and its manufacturer are subject to extensive regulatory requirements relating to manufacturing, labeling, packaging, adverse event reporting, storage, advertising and promotion for the product. If we fail to comply with the regulatory requirements of the FDA or other non-U.S. regulatory authorities, or if previously unknown problems with our products or manufacturing processes are discovered, we could be subject to administrative or judicially imposed sanctions, including: • • • • • • • • • • • restrictions on the products, manufacturers or manufacturing process; adverse inspectional observations (Form 483), warning letters, non-warning letters incorporating inspectional observations; civil or criminal penalties or fines; injunctions; product seizures, detentions or import bans; voluntary or mandatory product recalls and publicity requirements; suspension or withdrawal of regulatory clearances or approvals; total or partial suspension of production; imposition of restrictions on operations, including costly new manufacturing requirements; refusal to clear or approve pending applications or premarket notifications; and import and export restrictions. If imposed on us, any of these sanctions could have a material adverse effect on our reputation, business, results of operations and financial condition. Modifications to our Ekso GT and our future products may require new 510(k) clearances or premarlet approvals, or may require us to cease marketing or recall the modified products until clearances are obtained On April 4, 2016, the Company received clearance from the FDA to market its Ekso GT robotic exoskeleton for use in the treatment of individuals with hemiplegia due to stroke, individuals with spinal cord injuries at levels T4 to L5, and individuals with spinal cord injuries at levels of T3 to C7 (ASIA D), in accordance with the device’s labeling. On July 19, 2016, the Company received clearance from the FDA to expand/clarify the indications and labeling to expressly include individuals with hemiplegia due to stroke who have upper extremity function of at least 4/5 in only one arm. The Company’s prior cleared indications for use statement required that individuals with hemiplegia due to stroke have upper extremity function of at least 4/5 in both arms. 19 Table of Contents An element of our strategy is to continue to upgrade the Ekso GT to incorporate new software and hardware enhancements. Any modification to a 510(k)-cleared device, including our Ekso GT, that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, design, or manufacture, requires a new 510(k) clearance or, possibly, a PMA. The FDA requires every manufacturer to make this determination in the first instance based on the final guidance document issued by the FDA in October 2017 addressing when to submit a new 510(k) application due to modifications to 510(k)-cleared devices and a separate guidance document on when to submit a new 510(k) application due to software changes to 510(k)-cleared devices. Although largely aligned with the FDA’s longstanding guidance document issued in 1997, the 2017 guidance includes targeted changes intended to provide additional clarity on when a new 510(k) application is needed. The FDA may review our determinations regarding whether new clearances or approvals are necessary, and may not agree with our decisions. If the FDA disagrees with our determinations for any future changes, or prior changes to previously marketed products, as the case may be, we may be required to cease marketing or to recall the modified products until we obtain clearance or approval, and we may be subject to significant regulatory fines or penalties. The manufacture of our products is subject to extensive post-market regulation by the FDA. Our failure to meet strict regulatory requirements could require us to pay fines, incur other costs or even close our facilities. We are required to comply with the FDA’s Quality System Regulation, or QSR, which is a complex regulatory scheme that covers the procedures and documentation of the design, testing, production, process controls, quality assurance, labeling, packaging, handling, storage, distribution, installation, servicing and shipping of our marketed products. These regulatory requirements may significantly increase our production costs and may even prevent us from making our products in amounts sufficient to meet market demand. If we change our approved manufacturing process, the FDA may need to review the process before it may be used. The FDA enforces the QSR through periodic announced and unannounced inspections of manufacturing facilities. Failure to comply with regulatory requirements such as QSR may result in changes to labeling, restrictions on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, a requirement to repair, replace or refund the cost of any medical device we manufacture or distribute, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties which would adversely affect our business, operating results and prospects. Federal, state and non-U.S. regulations regarding the manufacture and sale of medical devices are subject to future changes. The complexity, timeframes and costs associated with obtaining marketing clearances are unknown. Although we cannot predict the impact, if any, these changes might have on our business, the impact could be material. We may be subject to fines, penalties or injunctions if we are determined to be promoting the use of our products for unapproved or "off-label" uses. Any cleared or approved product may be promoted only for its indicated uses and our promotional materials must comply with FDA and other applicable laws and regulations. We believe that the specific use for which our products are marketed fall within the scope of the indications for use that have been cleared by the FDA. However, if the FDA determines that our promotional materials or training constitutes promotion of an unapproved use, it could request that we modify our promotional materials or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, our reputation could be damaged and adoption of the products would be impaired. Failure to comply with anti-kickback and fraud regulations could result in substantial penalties and changes in our business operations. Although we do not provide healthcare services, submit claims for third-party reimbursement, or receive payments directly from Medicare, Medicaid or other third-party payers for our products, we are subject to healthcare fraud and abuse regulation and enforcement by federal, state and foreign governments, which could significantly impact our business. The principal U.S. federal laws implicated include those that prohibit (i) the filing of false or improper claims for federal payment, known as the false claims laws, (ii) unlawful inducements for the referral of business reimbursable under federally-funded health care programs, known as the anti-kickback laws, and (iii) health care service providers from seeking reimbursement for providing certain services to a patient who was referred by a physician who has certain types of direct or indirect financial relationships with the service provider, known as the Stark law. Many states have similar laws that apply to reimbursement by state Medicaid and other funded programs as well as in some cases to all payers. 20 Table of Contents 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 may be subject to penalties, including civil and criminal penalties, damages, fines, disgorgement, exclusion from governmental health care programs, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. Changes in law or regulation could make it more difficult and costly for us to manufacture, market and distribute our products or obtain or maintain regulatory approval of new or modified products. From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the regulatory approval, manufacture and marketing of regulated devices. In addition, FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly affect our business and our products. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of future products. In addition, FDA regulations and guidance are often revised or reinterpreted by the agency in ways that may significantly affect our business and our products. The recent presidential and congressional elections in the U.S. could result in significant changes in, and uncertainty with respect to, legislation, regulation and government policy that could significantly impact our business and the health care industry. It is impossible to predict whether legislative changes will be enacted or FDA regulations, guidance or interpretations changed, and what the impact of such changes, if any, may be. Any change in the laws or regulations that govern the clearance and approval processes relating to our current and future products could make it more difficult and costly to obtain clearance or approval for new products, or to produce, market, and distribute existing products. Significant delays in receiving clearance or approval, or the failure to receive clearance or approval, for any new products would have an adverse effect on our ability to expand our business. Healthcare changes in the U.S. and other countries, including recently enacted legislation reforming the U.S. healthcare system, could have a negative impact on our future operating results. In 2010, the Patient Protection and Affordable Care Act (“ACA”) was enacted into law. The legislation seeks to reform the United States healthcare system. It is far-reaching and is intended to expand access to health insurance coverage, improve quality and reduce costs over time. We expect the new law will have a significant impact upon various aspects of our business operations. The ACA reduces Medicare and Medicaid payments to hospitals, clinical laboratories and pharmaceutical companies, and could otherwise reduce the volume of medical procedures. These factors, in turn, could result in reduced demand for our products and increased downward pricing pressure. It is also possible that the ACA will result in lower reimbursements. While the ACA is intended to expand health insurance coverage to uninsured persons in the United States, the impact of any overall increase in access to healthcare on sales of our products remains uncertain. The new U.S. Presidential administration and the majority party in both Houses of the U.S. Congress have indicated their desire to repeal the Affordable Care Act. It is unclear whether, when and how that repeal will be effectuated and what the effect on the healthcare sector will be. However, in December 2017, the Tax Cuts and Jobs Act was enacted and signed into law, one part of which repeals the “individual mandate” introduced by the ACA starting in 2019. The repeal of the “individual mandate” may have an adverse effect on ACA insurance markets and lead to further legislative changes. In addition, the new law imposes a 2.3 percent excise tax on medical devices that will apply to United States sales of our medical device product. Although a moratorium was placed on the medical device excise tax in 2016 and 2017, absent further legislative action, the medical device excise tax will apply to sales of our medical device product beginning on January 1, 2018. The outlook for the healthcare sector is unclear, and we are unable to predict the future course of federal or state healthcare legislation and regulations. Changes in the law or regulatory framework that reduce our revenues or increase our costs could also harm our business, financial condition and results of operations and cash flows. 21 Table of Contents If our medical products, or malfunction of our medical products, cause or contribute to a death or a serious injury, we will be subject to medical device reporting regulations, which can result in voluntary corrective actions or agency enforcement actions. Under the FDA’s medical device reporting, or MDR, regulations, we are required to report to the FDA any incident in which our product may have caused or contributed to a death or serious injury or in which our product malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. For example, we have been informed of a limited number of events with respect to our Ekso GT devices that have been determined to be reportable pursuant to the MDR regulations. There were no reported patient injuries related to any of these events, and in each case we have filed the required MDR reports with the FDA. In addition, all manufacturers bringing medical devices to market in the European Economic Area are legally bound to report any incident that led or might have led to the death or serious deterioration in the state of health of a patient, user or other person, and which the manufacturer’s device is suspected to have caused, to the competent authority in whose jurisdiction the incident occurred. In such case, the manufacturer must file an initial report with the relevant competent authority, which would be followed by further evaluation or investigation of the incident and a final report indicating whether further action is required. The events described above that were reported to the FDA were also reported to the relevant EU regulatory authorities. We are also required to follow detailed recordkeeping requirements for all Company-initiated medical device corrections and removals, and to report such corrective and removal actions to the FDA if they are carried out in response to a risk to health and have not otherwise been reported under the MDR regulations. Any adverse event involving our products could result in future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection or enforcement action. Recalls of our products, or agency actions relating to our failure to comply with our reporting or recordkeeping obligations, could harm our reputation and financial results. Discovery of serious safety issues with our products, or a recall of our products either voluntarily or at the direction of the FDA or another governmental authority, could have a negative impact on us. The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture or in the event that a product poses an unacceptable risk to health. In addition, manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall by us could occur as a result of an unacceptable risk to health, component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. To date, we have initiated only one field action in which we voluntarily accelerated our maintenance schedule based on field usage. When a medical human exoskeleton is used by a paralyzed individual to walk, the individual relies completely on the exoskeleton to hold them upright. There are many exoskeleton components that, if they were to fail catastrophically, could cause a fall resulting in severe injury or death of the patient. Certain of our competitors have reported injuries caused by the malfunction of human exoskeleton devices (in at least one case to the FDA). Injuries caused by the malfunction or misuse of human exoskeleton devices, even where such malfunction or misuse occurs with respect to one of our competitor’s products, could cause regulatory agencies to implement more conservative regulations on the medical human exoskeleton industry, which could significantly increase our operating costs. Similarly, when an industrial exoskeleton is used by a healthy individual — for example to operate heavy machinery overhead — malfunction of the device at an inopportune moment could result in severe injury or death of the person using the device. Such occurrences could result in regulatory action on the part of OSHA or its foreign counterparts. Any future recalls of any of our products could divert managerial and financial resources, impair our ability to manufacture our products in a cost-effective and timely manner, and have an adverse effect on our reputation, results of operations and financial condition. In some circumstances, such adverse events could also cause delays in new product approvals. We may also be required to bear other costs or take other actions that may have a negative impact on our future sales and our ability to generate profits. 22 Table of Contents In addition, personal injuries relating to the use of our products could also result in product liability claims being brought against us. Any product liability claim brought against us, with or without merit, could result in substantial damages, be costly and time-consuming to defend and could increase our insurance rates or prevent us from securing insurance coverage in the future. We could be exposed to significant liability claims if we are unable to obtain insurance at adequate levels or otherwise protect ourselves against potential product liability claims. The testing, manufacture, marketing and sale of medical devices and industrial products entail the inherent risk of liability claims or product recalls. Although we maintain product liability insurance, the coverage is subject to deductibles and limitations, and may not be adequate to cover future claims. A successful product liability claim or product recall could inhibit or prevent the successful commercialization of our products, cause a significant financial burden on us, or both, which in either case could have a material adverse effect on our business and financial condition. Warranty claims or any other service and repairs provided by the Company at its expense could have a material adverse effect on our business. Sales of our Ekso GT generally include a one-year warranty for parts and services in the U.S. and a two-year warranty in Europe, the Middle East and Africa. We also generally provide customers with an option to purchase an extended warranty for up to an additional three years. The costs associated with such warranties, including any warranty-related legal proceedings, could have a material adverse effect on our results of operations, cash flows and liquidity. As we enhance our product and in an effort to build our brand and drive adoption, the Company has elected to incur increased service expenses related to an accelerated maintenance program, field corrections and the implementation of technological improvements developed subsequent to many of our units being placed into service, sometimes outside of its warranty and contractual obligations. Continuation of these activities could have a material adverse effect on our results of operations, cash flows and liquidity. If we are not able to both obtain and maintain adequate levels of third-party reimbursement for our products, it would have a material adverse effect on our business. Healthcare providers and related facilities are generally reimbursed for their services through payment systems managed by various governmental agencies worldwide, private insurance companies, and managed care organizations. The manner and level of reimbursement in any given case may depend on the site of care, the procedure(s) performed, the final patient diagnosis, the device(s) utilized, available budget, or a combination of these factors, and coverage and payment levels are determined at each payer’s discretion. The coverage policies and reimbursement levels of these third-party payers may impact the decisions of healthcare providers and facilities regarding which medical products they purchase and the prices they are willing to pay for those products. Reimbursement rates can also affect the acceptance rates of new technologies. We have no direct control over payer decision-making with respect to coverage and payment levels for our medical device products. Additionally, we expect many payers to continue to explore cost-containment strategies (e.g., comparative and cost-effectiveness analyses, so-called “pay-for-performance” programs implemented by various public and private payers, and expansion of payment bundling schemes such as Accountable Care Organizations, and other such methods that shift medical cost risk to providers) that may potentially impact coverage and/or payment levels for our current products or products we develop. In addition to the ACA, which is intended to reduce the cost of healthcare over time, initiatives sponsored by government agencies, legislative bodies and the private sector to limit the growth of healthcare costs, including price regulation and competitive pricing, are ongoing in markets where we do business. Pricing pressure has also increased in these markets due to continued consolidation among health care providers, trends toward managed care, the shift towards governments becoming the primary payers of health care expenses and laws and regulations relating to reimbursement and pricing generally. Reductions in reimbursement levels or coverage or other cost-containment measures could adversely affect customer demand or the price customers may be willing to pay for our products and could result in decreased revenue. 23 Table of Contents Clinical studies regarding our products may not provide sufficient data to either cause third-party payers to approve reimbursement or to make human exoskeletons a standard of care. Our business plan relies on broad adoption of human exoskeletons to provide neuro-rehabilitation in the form of gait training to individuals who have suffered a neurological injury or disorder. Although use of human exoskeletons in neuro-rehabilitation is new, use of robotic devices to provide gait training has been going on for over a decade and the clinical studies relating to such devices have had both positive and negative outcomes. Much of the rehabilitation community has rejected the use of such devices based on the data from some of these studies. Although we believe that human exoskeletons will outperform such robotic equipment, this has not been proven. Furthermore, it may prove impossible to prove an advantage in a timely manner, or at all, which could prevent broad adoption of our products. Part of our business plan relies on broad adoption of our robotic exoskeleton to provide “early mobilization” of individuals who have been immobilized by an injury, disease, or other condition. Although the health benefits of other methods of “early mobilization” have been demonstrated in clinical studies in fields such as stroke, those studies did not test early mobilization with human exoskeletons directly. To date, our device has been the subject of several clinical trials, some of which have been partially sponsored by us, but most of which are non-Ekso-sponsored independent studies conducted by rehabilitation institutions. Data from these studies was provided to the FDA as part of our 510(k) application submissions. In addition, there are several ongoing independent studies to investigate additional indications for use for our device, as well as to evaluate clinical and non-clinical outcomes of using the Ekso device, and we are currently in the planning stage for several Company-led studies. Further, we recently initiated a Company-sponsored clinical trial, entitled WISE (Walking Improvement for SCI with Exoskeletons), to evaluate improvement in independent gait speeds of SCI patients undergoing rehabilitation with the Ekso GT and to compare it to both conventional therapy and a control group. If current and future clinical trials do not provide sufficient data to support our belief that early mobilization through the use of exoskeletons improves health outcomes, or such studies actually contradict that belief, market acceptance of the human exoskeletons could fail to increase or could decrease and our business could be harmed. Any studies that we initiate, whether to drive market adoption and support commercialization, or to support additional product submissions or new claims, will be expensive and time consuming, which could harm our financial results. Initiating and completing clinical trials necessary to drive market adoption and support commercialization, or to support additional product submissions or new claims, is time consuming and expensive. Conducting successful clinical studies requires the enrollment of large numbers of patients, and suitable patients may be difficult to identify and recruit. Delays in patient enrollment or failure of patients to continue to participate in a clinical trial may cause an increase in costs and delays in future clearances or approvals of our products or result in the failure of the clinical trial. Such increased costs and delays or failures could adversely affect our business, results of operations and prospects. In addition, all clinical trial activities that we undertake are subject to extensive regulation and review by numerous governmental authorities both in the United States and abroad. Clinical trials intended to support a 510(k) applications or PMA must be conducted in compliance with the FDA’s Good Clinical Practice regulations and similar requirements in foreign jurisdictions. Sufficient and appropriate clinical protocols to demonstrate safety and efficacy may be required and we may not adequately develop such protocols to support future clearances and approvals. Compliance with these regulations is costly, and any failure to do so could delay or prevent us from using data obtained from such activities to support our claims that a product is safe and effective. The results of clinical trials may not support new product submissions or claims or may result in the discovery of adverse side effects. Despite considerable time and expense invested in clinical trials, the FDA may not consider any data that we obtain adequate to demonstrate safety and efficacy for future submissions. Even if our clinical trials are completed as planned, we cannot be certain that their results will support our intended claims or demonstrate that our product candidates are safe and effective for the proposed indicated uses, which could cause us to abandon a product candidate and may delay development of others. Moreover, the results of early clinical trials are not necessarily predictive of future results, and any product we advance into clinical trials may not have favorable results in later clinical trials. Any delay or termination of our clinical trials or studies could delay the filing of associated product submissions and, ultimately, our ability to commercialize products requiring submission of clinical data or relying on clinical data for market acceptance. 24 Table of Contents It is also possible that patients enrolled in a clinical trial will experience adverse side effects that are not currently part of the product candidate’s safety profile, which could cause us to delay or abandon development of such product Our business may suffer if we are not able to attract and retain key employees. Our success depends on our ability to identify, hire, train and retain highly qualified managerial, technical and sales and marketing personnel. In addition, as we introduce new products or services, we will need to hire additional personnel. Currently, competition for personnel with the required knowledge, skill and experiences is intense, particularly in the San Francisco Bay area, where we are headquartered, and we may not be able to attract, assimilate or retain such personnel. The inability to attract and retain the necessary managerial, technical and sales and marketing personnel could have a material adverse effect on our business, results of operations and financial condition. We will experience long and variable sales cycles, which could have a negative impact on our results of operations for any given quarter and may result in volatility in our stock price. The Ekso GT has a lengthy sale and purchase order cycle because it is a major capital item and generally requires the approval of senior management at purchasing institutions, which may contribute to substantial fluctuations in our quarterly operating results. Other factors that may cause our operating results to fluctuate include: • • • • • • • general economic uncertainties and political concerns; the introduction of new products or product lines; product modifications; the level of market acceptance of new products; the timing and amount of research and development and other expenditures; timing of the receipt of orders from, and product shipments to, distributors and customers; changes in the distribution arrangements for our products; • manufacturing or supply delays; • • the time needed to educate and train additional sales and manufacturing personnel; and costs associated with defending our intellectual property. In addition to these factors, expenditures are based, in part, on expected future sales. If sales levels in a particular quarter do not meet expectations, we may be unable to adjust operating expenses quickly enough to compensate for the shortfall of sales, and our results of operations may be adversely affected. International sales of our products account for a portion of our revenues, which will expose us to certain operating risks. If we are unable to successfully manage our international activities, our net sales, results of operations and financial condition could be adversely impacted. Our business currently depends in part on our activities in Europe and other foreign markets and we are actively looking to broaden our footprint in Asia. Our international activities are subject to a number of risks inherent in selling and operating abroad. These include: 25 Table of Contents • • • • • • failure of local laws to provide the same degree of protection against infringement of our intellectual property rights; protectionist laws and business practices that favor local competitors, which could slow our growth in international markets; the expense of establishing facilities and operations in new foreign markets; building an organization capable of supporting geographically dispersed operations; challenges caused by distance, language and cultural differences; challenges caused by differences in legal regulations, markets, and customer preferences, which may limit our ability to adapt our products or succeed in other regions; • multiple, conflicting, and changing laws and regulations, including complications due to unexpected changes in regulatory requirements, foreign laws, tax schemes, international import and export legislation, trading and investment policies, exchange controls and tariff and other trade barriers; • • • • • • foreign tax consequences; fluctuations in currency exchange rates and foreign currency translation adjustments; foreign exchange controls that might prevent us from repatriating income earned outside the United States; imposition of public sector controls; political, economic and social instability; and restrictions on the export or import of technology. Some of the countries in which we operate and seek to expand are in emerging markets where legal systems may be less developed or familiar to us. Other jurisdictions in which we conduct business may establish legal and regulatory regimes that differ materially from United States laws and regulations. Compliance with diverse legal requirements is costly and time-consuming and requires significant resources. Violations of one or more of these regulations in the conduct of our business could result in significant fines or monetary damages, criminal sanctions against us or our officers, prohibitions on doing business, unfavorable publicity and other reputational damage, restrictions on our ability to process information and allegations by our clients that we have not performed our contractual obligations. As we look to expand into China, we may be exposed to the additional risks of doing business in China. Our success in the Chinese markets may be adversely affected by China’s continuously evolving laws and regulations, including those relating to taxation, import and export tariffs, currency controls, anti-corruption, environmental regulations, indigenous innovation, and intellectual property rights and enforcement of those rights. Enforcement of existing laws or agreements may be inconsistent. In addition, changes in the political environment, governmental policies or United States-China relations could result in revisions to laws or regulations or their interpretation and enforcement, exposure of our proprietary intellectual property, increased taxation, restrictions on imports, import duties or currency revaluations, which could have an adverse effect on our business plans and operating results. If we are unable to meet and overcome these challenges, then our international operations may not be successful, which could adversely affect our net sales, results of operations and financial condition and limit our growth. The disruption or loss of relationships with vendors and suppliers for the components of our products could materially adversely affect our business. Our ability to manufacture and market our products successfully is dependent on relationships with both third party vendors and suppliers. Although most of the raw materials that we use to manufacture our products are readily available from a number of suppliers, we generally procure raw materials and components through purchase orders, with no guaranteed supply arrangements. Our inability to obtain sufficient quantities of various components, if and as required in the future, may subject us to: 26 Table of Contents • • • • • delays in delivery or shortages in components that could interrupt and delay manufacturing and result in cancellations of orders for our products; increased component prices and supply delays as we establish alternative suppliers; inability to develop alternative sources for product components; required modifications of our products, which may cause delays in product shipments, increased manufacturing costs, and increased product prices; and increased inventory costs as we hold more inventory than we otherwise might in order to avoid problems from shortages or discontinuance, which may result in write-offs if we are unable to use all such products in the future. In addition, failure of any one supplier’s components could result in a product recall, which could materially adversely affect our business, operations and cash flows. We may be unable to manage our growth and entry into new business areas. If demand for our exoskeleton products exceeds our capacity to provide services timely and efficiently, then we may need to expand our operations accordingly and swiftly. Our management believes that establishing industry leadership will require us to: • • • • test, introduce and develop new products and services including enhancements to our existing products; develop and expand the breadth of products and services offered; develop and expand our market presence through relationships with third parties; and generate satisfactory revenues from such expanded products or services to fund the foregoing requirements while obtaining and maintaining satisfactory profit margins. To be able to expand our operations in a cost-effective or timely manner and increase the overall market acceptance of our products and services in this manner, we will need additional capital and technical and managerial human resources. These additional resources may not be available to us. Our failure to timely and efficiently expand our operations and successfully achieve the four requirements listed above could have a material adverse effect on our business, results of operations and financial condition. New product introductions may adversely impact our financial results. We may introduce new products with enhanced features and extended capabilities from time to time. The products may be subject to various regulatory processes, and we may need to obtain and maintain regulatory approvals in order to sell our new products. If a potential purchaser believes that we plan to introduce a new product in the near future or if a potential purchaser is located in a country where a new product that we have introduced has not yet received regulatory approval, planned purchases may be deferred or delayed. As a result, new product introductions may adversely impact our financial results. The acquisition of other companies, businesses, or technologies could result in operating difficulties, dilution, and other harmful consequences. We may selectively pursue strategic acquisitions, any of which could be material to our business, operating results, and financial condition. Future acquisitions could divert management’s time and focus from operating our business. In addition, integrating an acquired company, business or technology is risky and may result in unforeseen operating difficulties and expenditures associated with integrating employees from the acquired company into our organization and integrating each company’s accounting, management information, human resources and other administrative systems to permit effective management. The anticipated benefits of future acquisitions may not materialize. Future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities or amortization expenses, or write-offs of goodwill, any of which could harm our financial condition. Future acquisitions may also require us to obtain additional financing, which may not be available on favorable terms or at all. 27 Table of Contents We may incur losses associated with currency fluctuations and may not be able to effectively hedge our exposure Our operating results are subject to volatility due to fluctuations in foreign currency exchange rates. Our primary exposure to fluctuations in foreign currency exchange rates relates to revenue and operating expenses denominated in currencies other than the U.S. dollar. The weakening of foreign currencies relative to the U.S. dollar adversely affects our foreign currency-denominated revenue. In the past, we have not hedged our exposures to foreign currencies or entered into any other derivative instruments and we have no current plans to do so. See “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” for additional discussion on the impact of foreign exchange risk. Natural or other disasters could disrupt our business and result in loss of revenue or in higher expenses. Natural disasters, terrorist activities, military conflict and other business disruptions could seriously harm our revenue and financial condition and increase our costs and expenses. Our corporate headquarters are located in California, a seismically active region. A natural disaster in any of our major markets in North America or Europe could have a material adverse impact on our operations, operating results and financial condition. Further, any unanticipated business disruption caused by Internet security threats, damage to global communication networks or otherwise could have a material adverse impact on our operating results. Risks Related to our Financial Condition We have a history of losses and we may not achieve or sustain profitability in the future. We have incurred losses in each fiscal year since our incorporation in 2005. Our net losses were $29.1 million, $23.5 million, and $19.6 million for the years ended December 31, 2017, 2016, and 2015, respectively. As of December 31, 2017, we had an accumulated deficit of $144.2 million. Our future profitability is dependent upon our ability to successfully execute our business plan. We can provide no assurance regarding when, if ever, we will become profitable. Even if we do become profitable, we may not be able to sustain or increase profitability on a quarterly or annual basis. Accordingly, we may continue to generate losses for the foreseeable future and, in the extreme case, discontinue operations. We may not be able to reduce the cost to manufacture or service our products as planned. Our business plan assumes that exoskeletons can be manufactured more inexpensively than they are currently being manufactured. However, we have not yet found a way to significantly reduce the manufacturing cost of our products and doing so may prove more difficult than expected or even impossible. For example, if expectations for greater functionality of the products drive costs up as other factors drive costs down, the result may be that the overall cost of manufacturing the product stays the same or even increases. Likewise, we currently provide service and support of our products for our customers at a high standard (both in and out of warranty), and plan on continuing to do so. Our business plan also assumes that as we continue to improve our product, we achieve improved levels of product reliability and decreased service cost and frequency, which also may prove more difficult than expected. We may not be able to leverage our cost structure or achieve better margins. Due to the early stage of our commercial efforts, and particularly the early stage of customer adoption of our products, our current sales and marketing, research and development, and general and administrative expenses are each a higher percentage of sales than they will need to be for us to reach profitability. While we do expect these expenses to grow as our business grows, we also expect these expenses to decline as a percentage of revenues over time. If we are unable to leverage these costs and grow revenues at a greater pace than these operating expenses as we expect, we will not be able to achieve viable operating margins and profitability. 28 Table of Contents If we are unable to obtain additional financing on acceptable terms, we may have to curtail our growth or cease our development plans and operations. The operation of our business and our growth efforts will require significant cash outlays and advance capital equipment expenditures and commitments. We have been largely dependent on capital raised through the sale of equity securities in various public and private offerings, and going forward will be largely dependent on capital raised in any future offerings, to implement our business plan and support our operations. Based upon our current cash resources, the recent rate of using cash for operations and investment, and assuming [modest increases in current revenue offset by incremental increases in expenses related to increased sales and marketing and research and development, and a potential increase in rental activity from our medical device business, the Company believes it has sufficient resources to meet its financial obligations well into 2019. The Company will require significant additional financing. The Company intends to pursue opportunities to obtain additional financing in the future through public or private equity and/or debt financings, corporate collaborations, or warrant solicitations. We anticipate for the foreseeable future that cash on hand and cash generated from operations will not be sufficient to meet our cash requirements, and that we will need to raise additional capital through investments to fund our operations and growth. We cannot assure you that we will be able to raise additional working or growth capital as needed on terms acceptable to us, if at all. If we are unable to raise capital as needed, we may be required to reduce the scope of our business development activities, which could harm our business plans, financial condition and operating results, or cease our operations entirely. Our reported financial results may be adversely affected by changes in our accounting policies or in accounting principles generally accepted in the United States. Generally accepted accounting principles in the United States are subject to interpretation by the Financial Accounting Standards Board, the American Institute of Certified Public Accountants, the Securities and Exchange Commission and various bodies formed to promulgate and interpret appropriate accounting principles. The accounting principles and accompanying accounting pronouncements, implementation guidelines and interpretations for many aspects of our business, including revenue recognition, are highly complex and involve subjective judgments. Some of these policies require the use of estimates and assumptions that may affect the value of our assets and liabilities, and financial results. We may be required or determine that it is appropriate to change our accounting policies or the manner in which they are implemented as circumstances change and additional information becomes known. A change in applicable rules, their interpretation, or their application could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change. Changes in tax laws or exposure to additional income tax liabilities could have a material adverse impact on our financial condition and results of operations. We are subject to income taxes as well as non-income based taxes, in both the U.S. and various jurisdictions outside the U.S. On December 22, 2017, the Tax Cuts and Jobs Act was enacted into law. This new law includes significant changes to the U.S. corporate income tax system, including a permanent reduction in the corporate income tax rate from 35% to 21%, limitations on the deductibility of interest expense and executive compensation and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system. The Company is currently assessing the impact of this legislation, but currently anticipates no major short-term impact. In addition, we are subject to ongoing tax audits in various jurisdictions. Tax authorities may disagree with certain positions we have taken and assess additional taxes and penalties. We regularly assess the likely outcomes of these audits in order to determine the appropriateness of our tax provision. However, there can be no assurance that we will accurately predict the outcomes of these audits, and the actual outcomes of these audits could have a material impact on our consolidated earnings and financial condition. 29 Table of Contents Risks Related to Our Securities We may raise additional funds in the future through the issuances of equity securities or debt, which funding may be dilutive to stockholders or impose operational restrictions on us. We may need to raise additional capital through the sale of equity securities or the issuance of short- and long-term debt. If we raise additional funds by issuing shares of our common stock, our stockholders will experience dilution. If we raise additional funds by issuing securities exercisable or convertible into shares of our common stock, our stockholders will experience dilution in the event the securities are exercised or converted, as the case may be, into shares of our common stock. Further, prices at which new investors would be willing to purchase our securities may be lower than the price at which existing stockholders purchased their shares, which may create downward pressure on the trading price of the common stock. In addition, the terms of any new securities may include liquidation or other preferences that may adversely affect the rights of our existing stockholders. Debt financing may involve agreements containing covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, issuing equity securities, making capital expenditures for certain purposes or above a certain amount, or declaring dividends. In addition, any equity securities or debt that we issue may have rights, preferences and privileges senior to those of the securities held by our stockholders. The ability of our Board of Directors to issue additional stock may prevent or make more difficult certain transactions, including a sale or merger of the Company. Our Board of Directors is authorized to issue up to 10,000,000 shares of preferred stock with powers, rights and preferences designated by it. Shares of voting or convertible preferred stock could be issued, or rights to purchase such shares could be issued, to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control of us. The ability of the Board of Directors to issue such additional shares of preferred stock, with rights and preferences it deems advisable, could discourage an attempt by a party to acquire control of us by tender offer or other means. Such issuances could therefore deprive stockholders of benefits that could result from such an attempt, such as the realization of a premium over the market price for their shares in a tender offer or the temporary increase in market price that such an attempt could cause. Moreover, the issuance of such additional shares of preferred stock to persons friendly to the Board of Directors could make it more difficult to remove incumbent officers and directors from office even if such change were to be favorable to stockholders generally. We have never paid and do not intend to pay cash dividends. Cash dividends have never been declared or paid on our common stock, and we do not anticipate such a declaration or payment for the foreseeable future. We expect to use future earnings, if any, to fund business growth. Therefore, stockholders will not receive any funds absent a sale of their shares of common stock. If we do not pay dividends, our common stock may be less valuable because a return on investment will only occur if our stock price appreciates. Being a public company is expensive and administratively burdensome. As a public reporting company, we are subject to the information and reporting requirements of the Securities Act of 1933, the Exchange Act of 1934 and other federal securities laws, rules and regulations related thereto, including compliance with the Sarbanes-Oxley Act. Complying with these laws and regulations requires the time and attention of our Board of Directors and management, and increases our expenses. Among other things, we are required to: 30 Table of Contents • maintain and evaluate a system of internal controls over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act and the related rules and regulations of the SEC and the Public Company Accounting Oversight Board; • maintain policies relating to disclosure controls and procedures; • • • prepare and distribute periodic reports in compliance with our obligations under federal securities laws; institute a more comprehensive compliance function, including with respect to corporate governance; and involve, to a greater degree, our outside legal counsel and accountants in the above activities. The costs of preparing and filing annual and quarterly reports, proxy statements and other information with the SEC and furnishing audited reports to stockholders is expensive and much greater than that of a privately-held company, and compliance with these rules and regulations may require us to hire additional financial reporting, internal controls and other finance personnel, and will involve a material increase in regulatory, legal and accounting expenses and the attention of management. We anticipate that these costs and compliance initiatives will increase as a result of the fact that we ceased to be an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, as of December 31, 2017. In particular, we are now subject to certain disclosure requirements that are applicable to other public companies that had not been applicable to us as an emerging growth company. These requirements include: · · · · compliance with the auditor attestation requirements in the assessment of our internal control over financial reporting; compliance with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements; full disclosure and analysis obligations regarding executive compensation; and compliance with regulatory requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. There can be no assurance that we will be able to comply with the applicable regulations in a timely manner, if at all. In addition, being a public company makes it more expensive for us to obtain director and officer liability insurance. In the future, we may be required to accept reduced coverage or incur substantially higher costs to obtain this coverage. These factors could also make it more difficult for us to attract and retain qualified executives and members of our Board of Directors, particularly directors willing to serve on our audit committee. Any failure to maintain effective internal control over our financial reporting could materially adversely affect us. Section 404 of the Sarbanes-Oxley Act of 2002 requires us to include in our annual reports on Form 10-K and quarterly reports on Form 10- Q an assessment by management of the effectiveness of our internal control over financial reporting. We previously reported a material weakness in our information technology general controls as of December 31, 2016, and as a result, determined that our internal control over financial reporting was not effective at December 31, 2016. As a natural course of business, management has, over the course of 2017, been working to further strengthen our internal controls. Specifically, we have increased segregation of duties and implemented a more robust accounting and enterprise resource planning system (which became operational in October 2017). While we believe that the policies, processes and procedures we have put in place over the course of 2017 will be sufficient to render our internal controls over financial reporting effective, our initiatives may not prove successful and management may not be able to conclude that our internal control over financial reporting is effective. Furthermore, even if management were to reach such a conclusion, if our independent registered public accounting firm is not satisfied with the adequacy of our internal control over financial reporting, or if the independent auditors interpret the requirements, rules or regulations differently than we do, then (if required in the future) they may decline to attest to management’s assessment or may issue a report that is qualified. Any of these events could result in a loss of investor confidence in the reliability of our financial statements, which in turn could negatively affect the price of our common stock In particular, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting, as required by Section 404. Our compliance with Section 404 may require that we incur substantial accounting expense and expend significant management efforts. The risks above do not necessarily comprise all of those associated with an investment in us. This Report contains forward looking statements that involve unknown risks, uncertainties and other factors that may cause our actual results, financial condition, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward looking statements. Factors that might cause such a difference include, but are not limited to, those set out above. 31 Table of Contents Item 1B. UNRESOLVED STAFF COMMENTS None. Item 2. PROPERTIES Our principal executive offices are currently located at 1414 Harbour Way South, Suite 1201, Richmond, CA 94804, where the Company leases approximately 45,000 square feet. In addition, we rent approximately 1,400 square feet of office space at Friesenweg 4, House 13, 4th floor, 22763 Hamburg, Germany. The Richmond office serves as headquarters for our medical device and industrial device sales segments, as well as our engineering services segment. The Hamburg office serves as our European headquarters for the medical device sales segment. The Company does not own any real property. Item 3. LEGAL PROCEEDINGS On December 28, 2017, the Company received letters from two different law firms purporting to represent two different stockholders of the Company. The letters alleged that the Company’s Proxy Statement, dated November 24, 2017, included a misrepresentation concerning the treatment of “broker non-votes” relating to a proposed amendment to increase the number of authorized shares of the Company’s common stock. According to the letters, the Proxy Statement asserted that “broker non-votes” would be counted as votes against the proposal when, in fact, they were counted as votes in favor of the proposal. The Company denies the allegations but will present the proposal for another stockholder vote in connection with its annual shareholder meeting. In December 2017, the Company disclosed that management had identified a material weakness in the Company’s internal controls over financial reporting due to a deficiency in the Company’s information technology (IT) general controls and segregation of duties. The Company has since implemented a more robust accounting and enterprise resource planning system. In response to the Company’s announcement, on January 2, 2018, and January 10, 2018, two securities class action lawsuits were filed: Behket v. Ekso Bionics Holdings, Inc., Thomas Looby and Maximilian Scheder-Bieschin (E.D.N.Y.), Case No. 1:18-cv-00001-KAM-CLP (filed Jan. 2, 2018); and Cheehy v. Ekso Bionics Holdings, Inc., Thomas Looby and Maximilian Scheder-Bieschin, (N.D. Cal.), Case no. 3:18-cv-00212 (filed Jan. 10, 2018). Both actions assert claims arising under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and both propose class periods which would include purchasers of the Company’s stock between March 15, 2017, and December 27, 2017. The Company’s management believes that the lawsuits are without merit, and the Company plans to defend against them. On February 5, 2018, a shareholder filed a derivative action in Nevada state court: D’Arcy, derivatively on behalf of Ekso Bionics Holdings, Inc., v. Thomas Looby, Maximilian Scheder-Bieschin, Steven Sherman, Daniel Boren, Marilyn Hamilton, Howard Palefsky, Jack Peurach, Stanley Stern, Ted Wang, and Amy Wendell, (Clark County, Nevada), Case No. a-18-768970-B (filed Feb. 5, 2018). The action alleges that the individual defendants breached their fiduciary duties to the Company by allowing it to have a material weakness in its internal controls. The allegations appear to be based, almost entirely, on the allegations contained in the two previously-filed securities class actions. The complaint alleges state law claims for breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The Company’s management believes that the lawsuit is without merit, and the Company plans to defend against it. We are also involved in other legal proceedings and claims arising from the normal course of our business, and we may in the future be subject to additional lawsuits and legal disputes. Item 4.

MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Market Information and Dividend Policy Our common stock has been traded on the Nasdaq Capital Market under the symbol “EKSO” since August 9, 2016. Prior to August 9, 2016, our common stock was eligible for quotation and traded on the OTC Market. The quotation of our common stock on the OTC market began on or about January 16, 2014. As of March 2, 2018, we had approximately 220 stockholders of record of our common stock. This number does not include stockholders whose shares are held in investment accounts by other entities. The Company believes the actual number of stockholders is greater than the number of holders of record. We have never declared or paid cash dividends on our common stock and do not intend to pay cash dividends in the foreseeable future. Payment of future dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, restrictions imposed by financing arrangements, if any, legal and regulatory restrictions on the payment of dividends, current and anticipated cash needs and other factors the board of directors deems relevant. The following table sets forth the high and low closing bid prices as reported on OTC Markets prior to August 9, 2016 and the high and low sales prices as reported by the Nasdaq Capital Market since August 9, 2016 for our common stock for the fiscal quarter indicated. The OTC Markets quotations reflect inter-dealer prices, without retail mark-up, mark-down or commission and may not represent actual transactions. All prices shown have been adjusted to give effect to the one-for-seven reverse stock split completed on May 4, 2016, discussed in Note 13 in the notes to our consolidated financial statements under the caption Capitalization and Equity Structure – Reverse Stock Split.

Such returns are based on historical results and are not intended to suggest future performance. The graph assumes $100 was invested in our common stock and in each of the indexes on January 16, 2014. Data for the Nasdaq Composite Index and the Nasdaq Medical Equipment Index assume reinvestment of dividends. We have never paid dividends on our common stock and we do not anticipate paying any dividends in the foreseeable future. The stockholder return shown on the graph below is not necessarily indicative of future performance, and we do not make or endorse any predictions as to future stockholder returns. 34 Table of Contents Item 6. SELECTED FINANCIAL DATA The following table sets forth certain financial data with respect to our business. The information set forth below is not necessarily indicative of results of future operations and should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 and the consolidated financial statements and related notes thereto in Item 8. The statement of operations data for the years ended December 31, 2017, 2016, and 2015 and the statement of financial position data for the years ended December 31, 2017 and 2016 are derived from, and are qualified by reference to, the audited consolidated financial statements that are included in this Report. The remaining financial data are derived from audited, consolidated financial statements which are not included in this Report. All share and per-share data has been retroactively adjusted to give effect to the one-for-seven reverse stock split discussed in Note 13 in the notes to our consolidated financial statements under the caption Capitalization and Equity Structure – Reverse Stock Split. Amounts in the following table are in thousands, except share and per share amounts: Statement of Operations Data: Revenue(1) Loss from operations Gain (loss) on warrant liability Net loss(2) Preferred deemed dividend(3) Net loss per share, basic Balance Sheet Data: Cash Total assets Note payable, net Warrant liability 2017 2016 2015 2014 2013 $ $ $ $ 7,353 $ (31,612) 3,909 (29,122) - (0.82) $ 27,813 $ 37,988 6,969 1,648 $ 14,221 $ (27,586) 4,286 (23,470) 10,345 (1.87) $ 16,846 $ 24,425 6,789 3,546 $ 8,661 $ (21,561) 2,505 (19,590) 4,655 (1.66) $ 19,552 $ 32,198 - 9,195 $ 5,327 $ (16,794) (16,485) (33,769) - (3.02) $ 25,190 $ 33,474 118 - $ 3,302 (10,294) 186 (11,887) - (3.97) 805 6,584 2,506 378 (1) In 2016, the Company began recognizing revenue related to its sales transactions on a multiple element approach in which revenue is recognized upon the delivery of the separate elements to the customer. As a result of this change, the Company recognized medical device revenue previously deferred at December 31, 2015 of $6,517 and associated cost of revenue of $4,159, resulting in additional gross profit, reduction in net loss from operations, and reduction of net loss applicable to common stockholders of $2,358, or $0.13 per share, in its results of operations for the year ended December 31, 2016. (2) The net loss recorded in 2017 included a non-cash gain of $3.9 million associated with the warrants issued in December 2015 and April 2017. The net loss recorded in 2016 included a non-cash gain of $4.3 million associated with the warrants issued in December 2015 that included an anti-dilution provision and a put option. The net loss recorded in 2015 included a non-cash gain of $2.5 million associated with the warrants issued in December 2015 that included an anti-dilution provision and a put option. See Note 13 to our consolidated financial statements, which appear under Item 8 of this Annual Report on Form 10-K. (3) The net loss recorded in 2014 included a non-cash charge of $16.5 million associated with the issuance of warrants in conjunction with our Merger and subsequent private placement offering that included an anti-dilution provision. The warrants were amended in November 2014 by a majority of common stock warrant holders to remove the anti-dilution provision. On December 23, 2015, the Company entered into an agreement to sell 15,000 shares of Series A Convertible Preferred Stock (the “Preferred Shares”) and warrants to purchase 2,122 shares of the Company’s common stock for cash of $13.7 million, net of issuance cost. Because the Preferred Shares were in-the-money on the date of issuance, the Company recognized a beneficial conversion feature of $3.3 million that was recorded as a non-cash preferred deemed dividend. In December 2015, 1,737 of the Preferred Shares were converted into 245,715 shares of common stock resulting in an additional $1.4 million non-cash preferred deemed dividend that related to the accretion of the discount associated with the warrants and stock issuance costs. Total preferred deemed dividends for the year ended December 31, 2015, were $4.7 million. During the year ended December 31, 2016, 13,263 Preferred Shares were converted into 2,309,531 shares of common stock resulting in a $10.3 million non-cash preferred deemed dividend. 35 Table of Contents Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion contains forward-looking statements. Actual results may differ significantly from those projected in the forward- looking statements. Factors that might cause future results to differ materially from those projected in the forward-looking statements include, but are not limited to, those discussed in "Risk Factors" and elsewhere in this Report. See also "Cautionary Note Regarding Forward-Looking Statements." On May 4, 2016, we effected a one-for-seven reverse stock split, reducing the number of our common shares outstanding on that date from 113.3 million shares to approximately 16.2 million shares. Concurrently with the reverse stock split, the number of authorized shares of our common stock was reduced proportionately, from 500,000,000 shares to 71,428,571 shares. Additionally, the exercise price and number of all outstanding options and warrants, the number of shares reserved for future issuance pursuant to our equity compensation plan, and the conversion ratio of our Series A Convertible Preferred Stock were all adjusted proportionately. All such amounts presented herein have been adjusted retroactively to reflect these changes. On October 30, 2017, the Board approved an amendment to the Company’s Articles of Incorporation to increase the number of shares of our common stock by 70,000,000 shares to 141,428,571 shares (the “Authorized Capital Amendment”), subject to the approval of such amendment by the stockholders. On December 21, 2017, a special meeting of the stockholders was convened (the “December Special Meeting”). In the definitive proxy statement dated November 24, 2017 filed by us with the SEC in respect of the December Special Meeting (the “November Proxy Statement”), the Board solicited the vote of the stockholders in favor of the Authorized Capital Amendment. The November Proxy Statement stated that broker non-votes in respect of the Authorized Capital Amendment would be counted as votes against the amendment. However, under relevant stock exchange rules, brokers had the discretionary authority to vote any shares held in their name on behalf of a beneficial owner (“Broker Shares”), and in respect of which the broker did not receive voting instruction from the beneficial owner, in favor of the Authorized Capital Amendment. As such, brokers voted approximately 17,628,410 Broker Shares, in respect of which the brokers had not received voting instructions from the beneficial owners of such shares, in favor of the Authorized Capital Amendment at the December Special Meeting. Accordingly, after taking into account such Broker Shares, the Authorized Capital Amendment was approved by the stockholders at the December Special Meeting. However, as disclosed in more detail under Item 3 to this Annual Report on Form 10-K, some stockholders of the Company have claimed that the disclosure in the November Proxy Statement in connection with the effect on the Authorized Capital Amendment of beneficial owners not providing voting instructions in respect of their Broker Shares was incorrect. Accordingly, stockholders will be asked to vote again on the Authorized Capital Amendment at our 2018 Annual Meeting of Shareholders. Further information about such vote will be provided in the Proxy Statement relating to our 2018 Annual Meeting of Shareholders, to be filed with the SEC within 120 days of December 31, 2017. Overview Restructuring In May 2017, the Company streamlined its operations and reduced its workforce by approximately 27 employees to lower operating expenses and reduce cash burn. The Company has since and will continue to focus its efforts on the commercialization of its proprietary Ekso GT for rehabilitation and its exoskeleton offerings for industrial applications. The restructuring plan was completed by the end of the second quarter of 2017. The Company recorded restructuring expense of $0.7 million for the year ended December 31, 2017, comprised of employee severance payments, stock compensation expense related to restricted stock units issued to terminated employees, and other severance related benefits. (Refer to Note 1, Organization - Restructuring of our consolidated financial statements, which appear under Item 8 of this Annual Report on Form 10-K). Capitalization and Ownership Structure The following discussion highlights the Company’s results of operations and the principal factors that have affected our financial condition as well as our liquidity and capital resources for the periods described, and provides information that management believes is relevant for an assessment and understanding of our financial condition and results of operations presented herein. The following discussion and analysis is based on the Company’s audited consolidated financial statements contained in this Annual Report on Form 10-K, which have been prepared in accordance with generally accepted accounting principles in the United States. You should read the discussion and analysis together with such financial statements and the related notes thereto. 36 Table of Contents On December 1, 2015, the Company through its wholly owned subsidiary, Ekso Bionics, acquired the mechanical balance and support arms technologies of Equipois, LLC, including the rights to the zeroG® and X-Ar® products. The initial purchase price for the acquired assets was paid for by the issuance of 111,607 shares of the Company’s common stock. The Company also agreed to issue additional shares of common stock based upon the achievement of certain post-closing performance criteria. On December 23, 2015, the Company entered into an agreement to sell 15,000 shares of Series A Convertible Preferred Stock (“Preferred Shares”), par value $0.001 and warrants to purchase 2,121,642 shares of the Company’s common stock at an exercise price of $8.75 per share for a term of five years (each, a “Warrant” and collectively, the “2015 Warrants”), to certain institutional investors in a registered direct offering at a purchase price of $1,000 for each Preferred Share and related Warrants for aggregate proceeds of $15,000,000. See Note 13 in the notes to our consolidated financial statements under the caption, Capitalization and Equity Structure – Convertible Preferred Stock and Capitalization and Equity Structure – Warrants – 2015 Warrants for a description of the Preferred Shares and 2015 Warrants. On August 12, 2016, the Company issued 3,750,000 shares of common stock at a price to the public of $4.00, resulting in proceeds to the Company of $13.7 million, net of the underwriting discount and issuance costs. On August 17, 2016, the Company issued an additional 266,751 shares of common stock as a result of the partial exercise of the underwriters’ overallotment option for additional proceeds of $1.0 million, net of the underwriting discount. In April 2017, the Company sold in a registered direct offering an aggregate of 3,732,356 shares of its common stock, par value $0.001 per share, and warrants to purchase 1,866,178 shares of common stock with an exercise price of $4.10 per share (“April 2017 Warrants”). The aggregate net proceeds of the transaction were approximately $10.9 million. The warrants were to become exercisable six months following the issuance date and were to expire five years from the date they became exercisable. In August 2017, the Company commenced a $34.0 million rights offering (“Rights Offering”) to its existing stockholders and certain warrant holders of the Company as of the record date of August 10, 2017. The subscription price was $1.00 per share and each subscription right gave holders the right to purchase 1.1608 shares of the Company’s common stock plus an oversubscription right, subject to availability. Concurrent with the rights offering, the Company entered into a purchase agreement (“the Backstop Investment Agreement”) with Puissance Cross-Border Opportunities II LLC (“Backstop Investor”). The Backstop Investment Agreement contemplated the purchase of any unsubscribed shares from the Rights Offering under the same terms, subject to a cap of 40% of the Company’s total outstanding shares. Under the Backstop Investment Agreement, 20,534,898 shares of our common stock (“Puissance Shares”) were issued to the Backstop Investor. The Puissance Shares were issued in an unregistered offering, and were subsequently registered by the Company for resale to the public pursuant to a registration rights agreement entered into with the Backstop Investor. In connection with the rights offering, the Company entered into a Warrant Repurchase and Amendment Agreement (“Repurchase Agreement”) with all of the holders of the April 2017 Warrants. Under the Repurchase Agreement, the Company agreed to repurchase the April 2017 Warrants from each holder at a price of $1.23 per underlying share, subject to the warrant holder’s participation in the Rights Offering. The Repurchase Agreement also permitted the holders of the April 2017 Warrants to use all or a portion of the consideration received as a result of the Company’s repurchase of the April 2017 Warrants to pay the subscription price for the exercise of their subscription rights in the Rights Offering. Upon the closing of the Rights Offering the Company repurchased warrants exercisable for 1,866,178 shares and applied consideration of $2.2 million to the subscribed shares in the Rights Offering. 37 Table of Contents The Company sold an aggregate of 13,465,102 shares of its common stock to existing stockholders and certain warrant holders in the Rights Offering for gross proceeds of $13.5 million, which after deducting expenses totaling approximately $0.3 million, resulted in net proceeds of $13.2 million from the Rights Offering; and 20,534,898 shares of its common stock to the Backstop Investor in a private placement in conjunction with the Rights Offering for gross proceeds of $20.5 million. Of the $0.3 million in direct issuance costs, warrants with a fair value of $0.1 million have been issued to an information agent. The warrants are classified as equity in the statement of stockholders’ equity. The Company intends to use the proceeds of the offering to broaden its footprint in Asia, support research, development and commercialization activities, and for working capital. Business We design, develop and sell exoskeleton technology that currently has applications in healthcare and industrial markets. Our wearable exoskeletons are worn over clothing and are mechanically controlled by a trained operator to augment human strength, endurance and mobility. Our exoskeleton technology serves multiple markets and can be used both by able-bodied users as well as by persons with physical disabilities. We have sold, rented or leased devices that (a) enable individuals with neurological conditions affecting gait (e.g., spinal cord injury or stroke) to rehabilitate and to walk again; and (b) allow industrial workers to perform heavy duty work for extended periods. In the U.S. there are about 5.9 million stroke and SCI rehabilitation sessions conducted on about 680,000 stroke and SCI patients at 16,900 facilities. Globally, there are an estimated 50,000 rehabilitation facilities. The first step to achieving our goal is for us to focus on selling our medical exoskeletons to rehabilitation centers and hospitals in the United States and Europe. Ekso Bionics began that effort with the February 2012 sale of Ekso, an exoskeleton for spinal cord injury (“SCI”) rehabilitation. We expanded that effort with the launch of our VariableAssist software. VariableAssist software enables users with any amount of lower extremity strength to contribute their own power for either leg to achieve self-initiated walking. Next, we introduced Ekso GT which builds on the experience of Ekso and VariableAssist, allowing us to expand our sales and marketing efforts beyond SCI- focused centers to centers supporting stroke and related neurological patients. We have continued to progress toward our goal with the roll out of our latest breakthrough innovation SmartAssist. SmartAssist can aid in promoting early mobility by training patients (PreGait) to walk in an exoskeleton, which should expand access to care to more patients. SmartAssist also includes next generation VariableAssist technology that provides more freedom for healthcare providers to allow patients to power themselves (FreeGait) in the most appropriate ways possible. Additionally, we have strengthened our competitive position as an exoskeleton manufacturer in medical rehabilitation by introducing a cloud-based software platform named EksoPulse Analytics, which gathers and transmits statistics and device information in real time during Ekso GT walking sessions. This feature enables more thorough patient care while reducing manual data entry. It also enables us to provide a higher level of service through early identification and thorough reporting of device errors, saving customers the time and expense of unnecessary on-site visits. Most recently, we also integrated FES interface capability with our Ekso GT for use by clinicians in EMEA. In parallel to the development and early commercialization of medical exoskeletons, we have begun to work on the commercialization of exoskeletons for able-bodied users, specifically for industrial and construction applications. According to a Bureau of Labor Statistics Report (2012), the U.S. spends over $21 billion per year on workplace related injuries. Our long- term goal is to build industrial products to significantly improve workforce productivity while dramatically reducing workplace related injuries and keeping workers healthy, strong, and safe. We took our first step toward this goal in 2016 with the introduction of the EksoZeroG, and this year, built upon that experience with the commercial rollout of the EksoVest, an upper body exoskeleton that elevates and supports a worker's arms to assist them with tasks ranging from chest height to overhead while enabling freedom of motion. In order to build the exoskeleton industry and solidify Ekso Bionics’ position as the industry leader, we will continue to act quickly and decisively with strong conviction and resolve. Our long-term goals of leadership in rehabilitation and industrial will require rapid innovation in areas where we already have strong experience, as well as parallel technologies that will enhance or accelerate our business. 38 Table of Contents Critical Accounting Policies, Estimates, and Judgments Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. We continually evaluate our estimates and judgments, our commitments to strategic alliance partners and the timing of the achievement of collaboration milestones. We base our estimates and judgments on historical experience and other factors that we believe to be reasonable under the circumstances. Materially different results can occur as circumstances change and additional information becomes known. Besides the estimates identified below that are considered critical, we make many other accounting estimates in preparing our financial statements and related disclosures. All estimates, whether or not deemed critical, affect reported amounts of assets, liabilities, revenues and expenses, as well as disclosures of contingent assets and liabilities. These estimates and judgments are also based on historical experience and other factors that are believed to be reasonable under the circumstances. Materially different results can occur as circumstances change and additional information becomes known, even for estimates and judgments that are not deemed critical. Revenue Recognition We recognize revenue when the four basic criteria of revenue recognition are met: · · · · Persuasive evidence of an arrangement exists. Customer contracts and purchase orders are generally used to determine the existence of an arrangement. The transfer of technology or products has been completed or services have been rendered. Evidence of shipment or customer acceptance, when applicable, is used to verify delivery. The sales price is fixed or determinable. We assess whether the cost is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. Collectability is reasonably assured. We assess collectability based primarily on the creditworthiness of the customer as determined by credit checks and analysis as well as the customer’s payment history. When collaboration, other research arrangements, and product sales include multiple-element revenue arrangements, we account for these transactions by determining the elements, or deliverables, included in the arrangement and determining which deliverables are separable for accounting purposes. We consider delivered items to be separable if the delivered item(s) have stand-alone value to the customer and delivery or performance of the undelivered item is considered probable and substantially in control of the vendor. In the first quarter of 2018, we will adopt Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09, as amended, will replace most existing revenue recognition guidance in U.S. GAAP. (Refer to Note 2, Summary of Significant Accounting Policies and Estimates – Recent Accounting Pronouncements of our consolidated financial statements, which appear under Item 8 of this Annual Report on Form 10-K). Medical Device Revenue and Cost of Revenue The Company builds medical device robotic exoskeletons for sale and capitalizes into inventory materials, direct and indirect labor, and overhead in connection with the manufacture and assembly of these units. 39 Table of Contents When the Company brought its first version medical device to market in 2012, the Company could not be certain as to the costs it would incur to support, maintain, service and upgrade these early stage devices. Primarily for this reason, prior to January 1, 2016, the sale of a device, associated software, initial training, and extended support and maintenance were deemed as a single unit of accounting due to the uncertainty of the Company’s follow-up maintenance and upgrade expenses, which were forecast to extend over three years. Accordingly, the revenue from the sales of the device and associated cost of revenue were deferred at the time of shipment. Upon completion of training, the amount of the arrangements were recognized as revenue and cost of revenue over a three year period on a straight line basis, while all service expenses, whether or not covered by the Company’s original warranty, extended warranty contracts, or neither, were recognized as incurred. Effective January 1, 2016, the Company determined it had established (i) separate individual pricing for training, extended warranty coverage, and out-of-contract service or repairs, (ii) sufficient historical evidence of customer buying patterns for extended warranty and maintenance coverage, and (iii) a basis for estimating and recording warranty and service costs to allow the Company to bifurcate its sales transactions into two separate units of accounting: (1) the device, associated software, original manufacturer warranty and training, if required, and (2) extended support and maintenance. As a result, in the first quarter of 2016, the Company began to recognize revenue related to its sales transactions on a multiple element approach in which revenue is recognized upon the delivery of the separate elements to the customer. Revenue relating to the undelivered elements is deferred using the relative selling price method, which allocates revenue to each element using the estimated selling prices for the deliverables when vendor-specific objective evidence or third-party evidence is not available. For sales on or after January 1, 2016, revenue and associated cost of revenue of medical devices is recognized when delivered, or training has been completed, if required. Revenue for extended maintenance and support agreements is recognized on a straight line basis over the contractual term of the agreement, which typically ranges from one to four years. As a result of this change, the Company recognized medical device revenue previously deferred at December 31, 2015 of $6.5 million and associated cost of revenue of $4.2 million, resulting in additional gross profit, reduction in net loss from operations, and reduction of net loss applicable to common stockholders of $2.4 million, or $0.13 per share, in its results of operations for the year ended December 31, 2016. In addition, the Company recorded $0.2 million for warranty expenses and a one-time charge of $0.9 million for a planned preventative maintenance and upgrade program associated with the devices it had sold prior to 2016 in the same time period. Industrial Sales Revenue and Cost of Revenue The Company builds industrial exoskeletons for sale and capitalizes into inventory materials, direct and indirect labor, and overhead in connection with the manufacture and assembly of these units. No right of return exists on sales of industrial exoskeletons. We assess collectability at the time of the sale and if collectability is not reasonably assured, the sale is deferred and not recognized until collectability is probable or payment is received. Typically, where product is produced and sold in the same country, title and risk of ownership transfer when the product is shipped. Products that are exported from a country for sale typically pass title and risk of ownership at the border of the destination country. Engineering Services Revenue and Cost of Revenue Collaborative arrangements typically consist of cost reimbursements for specific engineering and development spending, and future product royalty payments. Cost reimbursements for engineering and development spending are recognized as the related project labor hours are incurred in relation to all labor hours. Amounts received in advance are recorded as deferred revenue until the technology is transferred, services are rendered, or milestones are reached. Product royalty payments are recorded when earned under the arrangement. Government grants, which support our research efforts in specific projects, generally provide for reimbursement of approved costs as defined in the notices of grant awards. Grant revenue is recognized as the associated project labor hours are incurred in relation to total labor hours. There are some grants, such as the National Science Foundation grants, which we draw upon and spend based on budgets preapproved by the grantor. The cost of engineering services revenue includes payroll and benefits, subcontractor expenses and materials. All costs related to engineering services are expensed as incurred and included in cost of revenue. 40 Table of Contents Research and Development Research and development costs consist of costs incurred for internal research and development activities. These costs primarily include salaries and other personnel-related expenses, contractor fees, facility costs, supplies, and depreciation of equipment associated with the design and development of new products prior to the establishment of their technological feasibility. Such costs are expensed as incurred. Inventories, net Inventories are recorded at the lower of cost or net realizable value. Cost is determined using the average cost method. Parts from vendors are received and recorded as raw material. Once the raw materials are incorporated in the fabrication of the product, the related value of the component is recorded as work in progress (“WIP”). Direct and indirect labor and applicable overhead costs are also allocated and recorded to WIP inventory. Finished goods are comprised of completed products that are ready for customer shipment. The Company periodically evaluates the carrying value of inventory on hand for potential excess amounts over sales and forecasted demand. Excess and obsolete inventories identified, if any, are recorded as an inventory impairment charge to the consolidated statements of operations and comprehensive loss. Our estimate of write downs for excess and obsolete inventory is based on a detailed analysis of on-hand inventory and purchase commitments in excess of forecasted demand. Subsequent disposals of inventories are recorded as a reduction of an inventory reserve. Stock-based Compensation We measure stock-based compensation expense for certain stock-based awards made to employees and directors based on the estimated fair value of the award on the date of grant using the Black-Scholes option pricing model and recognize the fair value on a straight-line basis over the requisite service periods of the awards. Stock-based awards made to non-employees are measured and recognized based on the estimated fair value on the vesting date and re-measured at each reporting date. Our determination of the fair value of stock options on the date of grant using the Black-Scholes option pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. Because there is insufficient information available to estimate the expected term of the stock-based awards, we adopted the simplified method of estimating the expected term pursuant to SEC Staff Accounting Bulletin Topic 14. On this basis, we estimate the expected term of options granted by taking the average of the vesting term and the contractual term of the option. We have, from time to time, modified the terms of stock options granted to our employees. We account for the incremental increase in the fair value over the original award on the date of the modification as an expense for vested awards or over the remaining service (vesting) period for unvested awards. The incremental compensation cost is the excess of the fair value based measure of the modified award on the date of modification over the fair value of the original award immediately before the modification. Warrants Issued in Connection with Financings We generally account for warrants issued in connection with debt and equity financings as a component of equity, unless the warrants include a conditional obligation to issue a variable number of shares or there is a deemed possibility that we may need to settle the warrants in cash. For warrants where there is a possibility that we may have to settle the warrants in cash, we estimate the fair value of the issued warrants as a liability at each reporting date and record changes in the estimated fair value as a non-cash gain or loss in the consolidated statements of operations and comprehensive loss. The fair values of these warrants have been determined using the Binomial Lattice model (“Lattice”) and the Black-Scholes Option Pricing model. The Lattice model provides for assumptions regarding volatility, call and put features and risk-free interest rates within the total period to maturity. The Black-Scholes Model requires inputs, such as the expected term of the warrants, expected volatility and risk-free interest rate. These values are subject to a significant degree of judgment on our part. The Company’s common stock price represents a significant input that affects the valuation of the warrants. 41 Table of Contents Business Combinations We account for business combinations under the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations, where the total purchase price is allocated to the tangible and identified intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price is allocated using the information currently available, and may be adjusted, up to one-year from the acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. Contingent consideration, if any, is recorded at the acquisition date based upon the estimated fair value of the contingent payments. The fair value of the contingent consideration is re-measured each reporting period with any adjustments in fair value being recognized in our consolidated statement of operations and comprehensive loss. The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill. Going Concern We assess our ability to continue as a going concern at every interim and annual period in accordance with ASC 205-40, Presentation of Financial Statements – Going Concern. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. 42 Table of Contents Comparison of the year ended December 31, 2017 to the year ended December 31, 2016 (dollars in thousands): Revenue: Device and related Engineering services Total revenue Cost of revenue: Device and related Engineering services Total cost of revenue Gross profit Operating expenses: Sales and marketing Research and development General and administrative Restructuring Change in fair value, contingent consideration Total operating expenses Loss from operations Other income (expense): Interest expense Gain on warrant liability Loss on repurchase of warrants Interest income Other income (expense), net Total other income, net Years ended December 31, 2017 2016 Change % Change $ 7,315 $ 38 7,353 13,434 $ 787 14,221 5,270 14 5,284 10,715 559 11,274 (6,119) (749) (6,868) (5,445) (545) (5,990) 2,069 2,947 (878) -46% -95% -48% -51% -97% -53% -30% 13,156 9,483 10,715 659 (332) 33,681 10,997 8,879 10,853 - (196) 30,533 2,159 604 (138) 659 (136) 3,148 20% 7% -1% n/m(1) 69% 10% (31,612) (27,586) (4,026) 15% (648) 3,909 (1,067) - 296 2,490 (16) 4,286 - 12 (166) 4,116 (632) (377) (1,067) (12) 462 (1,626) 3,950% -9% n/m(1) -100% -278% -40% 24% -100% -14% Net loss (29,122) (23,470) (5,652) Less: Preferred deemed dividend Net loss applicable to common shareholders (1) Not meaningful Revenue - (29,122) $ 10,345 (33,815) $ (10,345) 4,693 $ Device and related revenue decreased $6.1 million, or 46%, for the year ended December 31, 2017, compared to the same period of 2016 primarily due to the absence in 2017 of revenue recognized in the year ended December 31, 2016 of $6.5 million of previously deferred revenue resulting from a change of an accounting estimate (see Note 2 in the notes to our consolidated financial statements under the caption Basis of Presentation and Summary of Significant Accounting Policies and Estimates - Medical Device Revenue and Cost of Revenue Recognition); partially offset by increased medical device and industrial sales. 43 Table of Contents We did not have any substantial engineering projects for the year ended December 31, 2017. Engineering services revenue was $0.8 million for the year ended December 31, 2016. Gross Profit Gross profit decreased $0.9 million, or 30%, for the year ended December 31, 2017 primarily due to the absence in 2017 of $2.4 million of gross profit from our change in accounting estimate related to the recognition of revenue and related costs during the year ended December 31, 2016 (see Note 2 in the notes to our consolidated financial statements under the caption Basis of Presentation and Summary of Significant Accounting Policies and Estimates - Medical Device Revenue and Cost of Revenue Recognition); partially offset by gross profit from increased medical device sales. Operating Expenses Sales and marketing expenses increased $2.2 million, or 20%, for the year ended December 31, 2017, compared to the same period of 2016 primarily due to an increase in marketing efforts related to the commercialization of the Company’s medical devices for rehabilitation and its exoskeleton offerings for industrial applications, an increase in clinical research activity, and increased average employee headcount notwithstanding the reduction in workforce in May 2017. Research and development expenses increased $0.6 million, or 7%, for the year ended December 31, 2017, compared to the same period of 2016 primarily due to labor being redirected to product innovation activities from billable engineering service projects which was recorded in cost of revenue, and increases in outside services and material purchases for the development of medical and industrial products, respectively. General and administrative expenses decreased $0.1 million, or 1%, for the year ended December 31, 2017, compared to the same period of 2016 primarily due to a decrease in average headcount and the absence of a $0.8 million non-cash stock compensation charge in the year ended December 31, 2016 related to the modification of stock options that had been granted to the then Chief Executive Officer. In addition, the 2016 period included a $0.3 million severance charge with respect to the departure of the then Chief Executive Officer. These decreases were partially offset by increased costs associated with business development activities in Asia. Restructuring expense of $0.7 million for the year ended December 31, 2017 includes employee severance payments of $0.4 million, stock compensation expense of $0.2 million related to restricted stock units issued to terminated employees, and $0.1 million of other related severance related benefits. Change in fair value, contingent liabilities of $0.3 million for the year ended December 31, 2017, included the changes of the fair value of the contingent consideration liability related to Equipois sales earn-outs and contingent success fee liability related to the outstanding debt with a lender. Other Income, Net Gain on revaluation of warrant liabilities decreased $0.4 million or 9%, for the year ended December 31, 2017, compared to the same period of 2016. We recorded a gain of $3.9 million on the revaluation of warrant liabilities related to warrants issued in 2015 and 2017 for the year ended December 31, 2017, compared to a gain of $4.3 million on the revaluation of warrant liabilities related to warrants issued in 2015 for the year ended December 31, 2016. Gains and losses on revaluation of warrants are primarily driven by changes in the Company’s stock price. Loss on repurchase of warrants of $1.1 million for the year ended December 31, 2017, was associated with the difference in the fair value of the April 2017 Warrants on the date of repurchase and the repurchase price. There was no comparable amount during the same period in 2016. Interest expense increased $0.6 million for the year ended December 31, 2017, compared to the same period of 2016, due to interest expense associated with the $7.0 million of debt obtained in December 2016. The Company had an insignificant amount of debt outstanding during the same period in 2016. 44 Table of Contents Other income, net increased $0.5 million for the year ended December 31, 2017, compared to the same period of 2016, due to unrealized gains and losses on foreign currency revaluations of monetary assets and liabilities. Preferred Deemed Dividend In the year ended December 31, 2016, 13,263 shares of convertible preferred stock were converted into approximately 2,309,531 shares of common stock, resulting in a $10.3 million non-cash preferred deemed dividend that related to the amortization of the discount associated with the warrants issued in December 2015. There was no comparable amount during the same period in 2017. 45 Table of Contents Comparison of the year ended December 31, 2016 to the year ended December 31, 2015 (dollars in thousands): Revenue: Device and related Engineering services Total revenue Cost of revenue: Device and related Engineering services Total cost of revenue Gross profit Operating expenses: Sales and marketing Research and development General and administrative Change in fair value, contingent consideration Total operating expenses Loss from operations Other income (expense): Interest expense Warrant issuance expense Gain on warrant liability Interest income Other expense, net Total other income, net Net loss Less: Preferred deemed dividend Net loss applicable to common shareholders (1) Not meaningful Revenue Years ended December 31, 2016 2015 Change % Change $ 13,434 $ 787 14,221 10,715 559 11,274 4,352 $ 4,309 8,661 3,926 3,556 7,482 9,082 (3,522) 5,560 6,789 (2,997) 3,792 2,947 1,179 1,768 209% -82% 64% 173% -84% 51% 150% 10,997 8,879 10,853 (196) 30,533 9,258 6,480 7,002 - 22,740 1,739 2,399 3,851 (196) 7,793 19% 37% 55% n/m(1) 34% (27,586) (21,561) (6,025) 28% (16) - 4,286 12 (166) 4,116 (13) (487) 2,505 11 (45) 1,971 (3) (487) 1,781 1 (121) 2,145 (23,470) (19,590) (3,880) 10,345 (33,815) $ 4,655 (24,245) $ 5,690 (9,570) $ 23% -100% 71% 9% 269% 109% 20% 122% 39% Device and related revenue was $13.4 million for the year ended December 31, 2016. Contributing to this revenue was $6.5 million of previously deferred revenue that was recognized as a result of a change of an accounting estimate related to revenue recognition. Revenue also includes $4.7 million of revenue derived from medical device sales during the period, $0.9 million of medical device service revenues, $0.1 million of medical device license revenue, and $1.2 million of industrial sales revenue. Device and related revenue was $4.4 million for the year ended December 31, 2015. This amount includes $3.6 million derived from current and prior year sales that was amortized on a straight-line basis during the period, $0.1 million of medical device license revenue, and $0.7 million of medical device service revenue. See Note 2 in the notes to our consolidated financial statements under the caption Basis of Presentation and Summary of Significant Accounting Policies and Estimates – Medical Device Revenue and Cost of Revenue Recognition for a discussion on the Company’s 2016 change in an accounting estimate related to revenue recognition. 46 Table of Contents Engineering service revenue was $0.8 million for the year ended December 31, 2016 compared to $4.3 million for the same period in the prior year. This result reflects the strategic decision earlier in the year to shift our engineering resources away from billable engineering services to the Company’s internal development efforts both for our next generation home/wellness device and for able-bodied industrial offerings. Gross Profit Gross profit for the year ended December 31, 2016 was $2.9 million, of which $2.7 million was attributable to device and related revenue. Medical device gross profit was $2.4 million, industrial gross profit was $0.3 million and engineering services gross profit was $0.2 million. The medical gross profit includes $1.2 million related to the change in accounting estimate, made up of $2.4 million for shipments made prior to January 1, 2016 which is offset by $0.9 million of maintenance and $0.2 million of warranty expenses, both of which relate to devices sold prior to 2016. Gross profit for the year ended December 31, 2015 was $1.2 million. This amount includes $0.4 million related to medical device sales and $0.8 million for engineering services. See Note 2 in the notes to our consolidated financial statements under the caption Basis of Presentation and Summary of Significant Accounting Policies and Estimates – Medical Device Revenue and Cost of Revenue Recognition. Operating Expenses Sales and marketing expenses increased $1.7 million, or 19%, during the year ended December 31, 2016 compared to the year ended December 31, 2015. The increase includes $1.0 million related to our industrial business, comprised of $0.2 million in travel, tradeshows and user trials and $0.7 million in employee compensation expense. The increase also includes $0.7 million related to our medical device business, which was primarily driven by the use of consultants for clinical studies, reimbursement and marketing. Research and development expenses increased $2.4 million, or 37%, during the year ended December 31, 2016 compared to the year ended December 31, 2015. The increase includes $1.2 million related to our industrial business, which was primarily driven by a reallocation and increase in headcount. The increase also includes $1.2 million related to the aforementioned shift of resources from engineering services to internal medical device development efforts. General and administrative expenses increased $3.9 million, or 55%, during the year ended December 31, 2016 compared to the year ended December 31, 2015. The increase was primarily driven by an increase of $2.4 million in employee compensation expense, which included a non-cash stock-based compensation expense increase of $1.1 million, one-time severance expense of $0.3 million and an increase in regulatory compliance personnel of $0.3 million. Stock-based compensation expense included a one-time $0.8 million non-cash charge related to the modification of stock options previously granted to our former Chief Executive Officer. Depreciation and amortization expenses in general and administrative expenses increased $0.6 million, primarily related to acquiring assets from Equipois in December 2015. A decrease in absorption of direct and indirect operating costs in inventory in 2016 as compared to 2015 also contributed $0.6 million to the increase in general and administrative expenses. Change in fair value, contingent consideration reflects a non-cash gain of $0.2 million during the year ended December 31, 2016, with no comparable amount in the prior period. This gain reflects the difference in the amount payable under our agreement with Equipois with respect to 2016 supply and sales earn-outs, based on the target achievement, and the consideration transferred, due to a difference between our stock price and the price floor of $7.00 specified in the Equipois Asset Purchase Agreement. The contingent consideration for the first earn-out period will be paid in the first quarter of 2017. 47 Table of Contents Other Income, Net Other income, net reflects a change of $2.1 million, or 109%, during the year ended December 31, 2016 compared to the year ended December 31, 2015. Due to a decrease in our per share stock price and the removal of the anti-dilution rights related to the 2015 Warrants, the warrant liability was reduced by $4.3 million, resulting in a non-cash gain. The 2015 results reflect a similar change in fair value of the warrant liability, related to the warrants issued in December of 2015, due to a decrease in our stock price from the transaction date to December 31, 2015. See Note 13 in the notes to our consolidated financial statements under the caption Capitalization and Equity Structure – 2015 Warrants for a description of the warrants, including the method and inputs used to estimate their fair value. Preferred Deemed Dividend On December 23, 2015, the Company entered into an agreement to sell 15,000 shares of Series A convertible preferred stock. Because the preferred shares were in-the-money on the date of issuance, the Company recognized a beneficial conversion feature of $3.3 million that was recorded as a non-cash preferred deemed dividend. In December 2015, 1,737 shares of Preferred Shares were converted into 245,715 shares of common stock resulting in an additional $1.4 million non-cash preferred deemed dividend that related to the accretion of the discount associated with the warrants and stock issuance costs. Total preferred deemed dividends for the year ended December 31, 2015, were $4.7 million. During the year ended December 31, 2016, the remaining 13,263 shares of convertible preferred stock were converted to 2,309,531 shares of common stock. The conversions resulted in the recognition of additional non-cash preferred stock dividends of $10.3 million. See Note 13 in the notes to our consolidated financial statements under the caption Capitalization and Equity Structure – Convertible Preferred Stock for additional information. Financial Condition, Liquidity and Capital Resources Since the Company’s inception, we have devoted our efforts toward the development of exoskeletons for the medical, military and industrial markets, toward the commercialization of our medical exoskeletons to rehabilitation centers and toward raising capital. We are considered to be in the early commercialization stage. We have financed our operations primarily through the issuance and sale of equity securities for cash consideration and through convertible and promissory notes, as well as from government research grant awards and strategic collaboration payments. Cash and Working Capital Cash on hand at December 31, 2017 was $27.8 million, compared to $16.8 million at December 31, 2016. Since the Company’s inception, we have incurred recurring net losses and negative cash flows from operations. We have incurred net losses of $29.1 million, $23.5 million, and $19.6 million for the years ended December 31, 2017, 2016, and 2015, respectively. In addition, our operating activities have used $31.2 million, $25.0 million, and $18.3 million in cash for the years ended December 31, 2017, 2016, and 2015, respectively. Liquidity and Capital Resources As of December 31, 2017, the Company had an accumulated deficit of $144.2 million and cash on hand of $27.8 million. Largely as a result of significant research and development activities related to the development of the Company’s advanced technology and commercialization of this technology into its medical device business, the Company has incurred significant operating losses and negative cash flows from operations since inception. The Company has also recognized significant non-cash losses in previous periods associated with the revaluation of certain securities, which have contributed significantly to its accumulated deficit. In the year ended December 31, 2017, the Company used $31.2 million of cash in its operations. In 2017, management took several actions to alleviate the substantial doubt about the Company’s ability to continue as a going concern that existed as of the date of issuance of the December 31, 2016 consolidated financial statements, including, but not limited to, the following: · · streamlining its operations and reducing its workforce by approximately 27 employees to lower operating expenses and reduce cash burn; conducting a registered direct offering of 3,732,356 shares of its common stock for net proceeds of $10.9 million; and 48 Table of Contents · conducting a rights offering, which resulted in the issuance of an aggregate of 13,465,102 shares of its common stock for net proceeds of $13.2 million and concurrently selling 20,534,898 shares of its common stock to an affiliate of the Backstop Investor in a private placement for proceeds of $20.5 million. With cash on hand of $27.8 million as of December 31, 2017, the Company believes that it currently has sufficient cash to fund its operations beyond the look forward period one year from the issuance of the December 31, 2017 consolidated financial statements, which appear under Item 8 of this Annual Report on Form 10-K. The Company’s actual capital requirements may vary significantly and will depend on many factors. The Company plans to continue its investments (i) in its clinical, sales and marketing initiatives to accelerate adoption of the Ekso robotic exoskeleton in the rehabilitation market, (ii) in its research, development and commercialization activities with respect to an Ekso robotic exoskeleton for home use, and/or (iii) in the development and commercialization of able-bodied exoskeletons for industrial use. Consequently, the Company may require significant additional financing in the future, which the Company intends to raise through corporate collaborations, public or private equity offerings, debt financings, or warrant solicitations. Sales of additional equity securities by us could result in the dilution of the interests of existing stockholders. There can be no assurance that financing will be available when required in sufficient amounts, on acceptable terms or at all. In the event that the necessary additional financing is not obtained, the Company may be required to further reduce its discretionary overhead costs substantially, including research and development, general and administrative, and sales and marketing expenses or otherwise curtail operations. Cash and Cash Equivalents The following table summarizes the sources and uses of cash for the periods stated (in thousands): Years ended December 31, 2016 2017 2015 Cash, beginning of period Net cash used in operating activities Net cash used in investing activities Net cash provided by financing activities Effect of exchange rate changes on cash Cash, end of period $ $ 16,846 $ (31,226) (456) 42,568 81 27,813 $ 19,552 $ (24,997) (1,096) 23,307 80 16,846 $ 25,190 (18,269) (1,492) 14,124 (1) 19,552 49 Table of Contents Net Cash Used in Operating Activities Net cash used in operations increased $6.2 million, or 25%, for the year ended December 31, 2017, compared to the same period of 2016 primarily due to increases in cash expenditures toward marketing efforts related to the commercialization of the Company’s medical devices for rehabilitation and exoskeleton offerings for industrial applications, business development activities in Asia, product innovation activities for the development of medical and industrial products, and clinical research activities. In addition, inventory levels of our industrial products increased primarily due to the timing of sales. Net cash used in operations increased $6.7 million, or 37%, for the year ended December 31, 2016, compared to the same period of 2015 primarily due to increases in cash expenditures toward the development of our initial commercial industrial products, related to obtaining FDA clearance and updating our marketing strategy as such. Additionally in 2016, we formed our German subsidiary, Ekso Bionics GMBh. Net Cash Used in Investing Activities Net cash used in investing activities of $0.5 million, $1.1 million, and $1.5 million during the years ended December 31, 2017, 2016, and 2015, respectively, was to acquire property and equipment, including expansion of our company-owned fleet of Ekso units used to rent and loan to customers, and for demonstrations to potential customers. Net Cash Provided by Financing Activities Net cash provided by financing activities of $42.6 million for the year ended December 31, 2017 was driven by proceeds from the sale of common stock related to the Rights Offering in August 2017 and the equity financing in April 2017. Net cash provided by financing activities of $23.3 million for the year ended December 31, 2016 included proceeds from the sale of common stock related to the equity financing in August 2016 and issuance of long-term debt, offset by expenses paid related to the December 2015 issuance of convertible preferred stock. Net cash provided by financing activities of $14.1 million during the year ended December 31, 2015 included proceeds from the December 2015 issuance of 15,000 Preferred Shares and Warrants to purchase 2.1 million shares of common stock. Off-Balance Sheet Arrangements Our liquidity is not dependent on the use of off-balance sheet financing arrangements (as that term is defined in Item 303(a) (4) (ii) of Regulation S-K) and as of December 31, 2017, we had no such arrangements. There has been no material change in our contractual obligations other than in the ordinary course of business since our fiscal year ended December 31, 2017. Contractual Obligations and Commitments The following table summarizes our outstanding contractual obligations, including interest payments, as of December 31, 2017 and the effect those obligations are expected to have on our liquidity and cash flows in future periods (in thousands): Term loan Facility operating leases Capital lease Total Total Less than one year 1-3 Years 3-5 Years After 5 Years Payments Due By Period $ $ 8,039 $ 2,746 96 10,881 $ 2,565 $ 622 37 3,224 $ 5,033 $ 1,858 59 6,950 $ 441 $ 266 - 707 $ - - - - In addition to the table above, which reflects only fixed payment obligations, we have two license agreements to maintain exclusive rights to certain patents. Under these license agreements, we are required to pay 1% of net sales of products sold to entities other than the U.S. government. In the event of a sublicense, we will owe 21% of license fees and must pass through 1% of the sub-licensee’s net sales of products sold to entities other than the U.S. government. The license agreements also stipulate minimum annual royalties of $50,000 per year. In connection with our acquisition of Equipois in December 2015, we assumed the rights and obligations of Equipois under a license agreement with, the developer of certain intellectual property related to mechanical balance and support arm technologies, which grants us an exclusive license with respect to the technology and patent rights for certain fields of use. Pursuant to the terms of the license agreement, we will be required to pay a single-digit royalty on net receipts, subject to a $50,000 annual minimum royalty requirement.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Foreign Currency Risk We report our financial results in U.S. dollars; however we conduct business in foreign countries. For U.S. reporting purposes, we translate all assets and liabilities of our non-U.S. subsidiaries at the period-end exchange rate, equity at historical exchange rates, and revenue and expenses at the average exchange rates in effect during the periods. The net effect of these translation adjustments is shown in the accompanying consolidated financial statements as a component of stockholders’ equity. We generate a portion of our revenue and collect receivables in foreign currencies outside of the U.S. and, as such, we have foreign currency exposure. Currently, we sell our products mainly in United States dollars, Euros, and British Pounds although we may in the future transact business in other currencies. Future fluctuations in the foreign exchange rates of these currencies can result in foreign exchange gains and losses which may impact our financial results. In the past, we have not hedged our exposures to foreign currencies or entered into any other derivative instruments and we have no current plans to do so. For the year ended December 31, 2017, sales denominated in foreign currencies were approximately 27% of total revenue. A hypothetical 10% increase in the United States dollar exchange rate used would have resulted in a $0.2 million decrease to revenues for 2017. Interest Rate Risk Our exposure to market rate risk for changes in interest rates relates primarily to our term loan. The variable interest rate related to our long-term debt is charged at a floating rate based on a U.S. 30 day London Interbank Offered Rate (“LIBOR”) plus 5.41%. A hypothetical 10% change in the LIBOR rate would have an immaterial impact on our annualized interest expense. 51 Table of Contents ITEM 8.

Richmond, California Opinion on Internal Control over Financial Reporting We have audited Ekso Bionics Holdings, Inc.’s (the “Company’s”) internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and our report dated March 13, 2018 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A, Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit of internal control over financial reporting in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ OUM & CO.

Organization Description of Business Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) Ekso Bionics Holdings, Inc. (the “Company”) designs, develops and sells exoskeleton technology that has applications in healthcare and industrial markets. Our wearable exoskeletons are worn over clothing and are mechanically controlled by a trained operator to augment human strength, endurance and mobility. Our exoskeleton technology serves multiple markets and can be used both by able-bodied users as well as by persons with physical disabilities. We have sold, rented or leased devices that (a) enable individuals with neurological conditions affecting gait (e.g., spinal cord injury or stroke) to rehabilitate and to walk again; and (b) allow industrial workers to perform heavy duty work for extended periods. Unless otherwise indicated, all dollar and share amounts included in these notes to the consolidated financial statements are in thousands. Liquidity and Going Concern As of December 31, 2017, the Company had an accumulated deficit of $144,154 and cash on hand of $27,813. Largely as a result of significant research and development activities related to the development of the Company’s advanced technology and commercialization of this technology into its medical device business, the Company has incurred significant operating losses and negative cash flows from operations since inception. The Company has also recognized significant non-cash losses in previous periods associated with the revaluation of certain securities, which have contributed significantly to its accumulated deficit. In the year ended December 31, 2017, the Company used $31,226 of cash in its operations. In 2017, management took several actions to alleviate the substantial doubt about the Company’s ability to continue as a going concern that existed as of the date of issuance of the December 31, 2016 consolidated financial statements, including, but not limited to, the following: · · · streamlining its operations and reducing its workforce by approximately 27 employees to lower operating expenses and reduce cash burn; conducting a registered direct offering of 3,732 shares of its common stock for net proceeds of $10,919; and conducting a rights offering, which resulted in the issuance of an aggregate of 13,465 shares of its common stock for net proceeds of $13,179 and concurrently selling 20,535 shares of its common stock to an affiliate of the Backstop Investor in a private placement for proceeds of $20,535. With cash on hand of $27,813 as of December 31, 2017, the Company believes that it currently has sufficient cash to fund its operations beyond the look forward period of one year from the issuance of these consolidated financial statements. The Company’s actual capital requirements may vary significantly and will depend on many factors. The Company plans to continue its investments (i) in its clinical, sales and marketing initiatives to accelerate adoption of the Ekso robotic exoskeleton in the rehabilitation market, (ii) in its research, development and commercialization activities with respect to an Ekso robotic exoskeleton for home use, and/or (iii) in the development and commercialization of able-bodied exoskeletons for industrial use. Consequently, the Company may require significant additional financing in the future, which the Company intends to raise through corporate collaborations, public or private equity offerings, debt financings, or warrant solicitations. Sales of additional equity securities by us could result in the dilution of the interests of existing stockholders. There can be no assurance that financing will be available when required in sufficient amounts, on acceptable terms or at all. In the event that the necessary additional financing is not obtained, the Company may be required to further reduce its discretionary overhead costs substantially, including research and development, general and administrative, and sales and marketing expenses or otherwise curtail operations. 60 Table of Contents Restructuring Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) In May of 2017, the Company streamlined its operations and reduced its workforce by approximately 27 employees (“Restructuring”) to lower operating expenses and reduce cash burn. Since the announcement of the restructuring event, the Company has focused and will continue to focus its efforts on the commercialization of its proprietary Ekso GT for rehabilitation and exploration of potential strategic alternatives to accelerate product and market adoption of our industrial products. The restructuring plan was completed by the end of the second quarter of 2017. The Company recorded restructuring expense of $659 for the year ended December 31, 2017, which was comprised of employee severance payments of $473, stock compensation expense of $186 related to restricted stock units issued to terminated employees (refer to Note 13, Stock-Based Compensation for issuance of restricted stock units) and other severance related benefits. As of December 31, 2017, no accrued restructuring cost remains on the Company’s consolidated balance sheet. The following table summarizes accrued restructuring costs as of December 31, 2017: Balance at December 31, 2016 Restructuring charges Cash payments Stock based compensation expense Balance at December 31, 2017 2. Summary of Significant Accounting Policies and Estimates Principles of Consolidation and Basis of Presentation Employee Severance and Other Benefits $ $ - 659 (473) (186) - The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included and are normal and recurring in nature All significant intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to prior year amounts to conform to the current year’s presentation. Such reclassifications had no net effect on previously reported financial results. All common share and per share amounts have been adjusted to reflect the one-for-seven reverse stock split completed on May 4, 2016. See Note 13, Capitalization and Equity Structure – Reverse Stock Split. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the balance sheet, and the reported amounts of revenues and expenses during the reporting period. For the Company, these estimates include, but are not limited to: revenue recognition, deferred revenue and the deferral of associated costs, valuation of acquired intangible assets and goodwill, useful lives assigned to long-lived assets, realizability of deferred tax assets, valuation of common and preferred stock warrants, the valuation of options, and contingencies. Actual results could differ from those estimates. 61 Table of Contents Foreign Currency Translation Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) The assets and liabilities of foreign subsidiaries, where the local currency is the functional currency, are translated from their respective functional currencies into U.S. dollars at the rates in effect at the balance sheet date and revenue and expense amounts are translated at average rates during the period, with resulting foreign currency translation adjustments recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. Where the U.S. dollar is the functional currency, foreign currency re-measurement adjustments are recorded in other expense, net in the accompanying consolidated statements of operations and comprehensive loss. Gains and losses realized from transactions, including related party balances not considered permanent investments, that are denominated in currencies other than an entity’s functional currency are included in other expense, net in the accompanying consolidated statements of operations and comprehensive loss. Accumulated Other Comprehensive Income (Loss) Accumulated other comprehensive income (loss) reported on our consolidated balance sheets consists of foreign currency translation adjustments. The change in accumulated other comprehensive income (loss) presented on the consolidated balance sheets for the year ended December 31, 2017, is reflected in the table below net of tax: Balance at December 31, 2016 Current period other comprehensive loss Balance at December 31, 2017 Cash and Cash Equivalents Foreign Currency Translation 79 $ (419) (340) $ The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. The Company’s cash is deposited in bank accounts with the Company’s primary cash management bank. The Company places its cash and cash equivalents in highly liquid instruments with, and in the custody of, financial institutions with high credit ratings. The Company did not have any cash equivalents or investments in money market funds as of December 31, 2017 and 2016. Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and accounts receivable. The Company maintains our cash accounts in excess of federally insured limits. However, the Company believes it is not exposed to significant credit risk due to the financial position of the depository institutions in which these deposits are held. The Company extends credit to customers in the normal course of business and performs ongoing credit evaluations of its customers. Concentrations of credit risk with respect to accounts receivable exist to the full extent of amounts presented in the consolidated financial statements. The Company does not require collateral from its customers to secure accounts receivable. 62 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) Accounts receivable are derived from the sale of products shipped and services performed for customers located in the U.S. and throughout the world. Invoices are aged based on contractual terms with the customer. The Company reviews accounts receivable for collectability and provides an allowance for potential credit losses. The Company has not experienced material losses related to accounts receivable during the years ended December 31, 2017 and December 31, 2016. Many of the sales contracts with customers outside of the U.S. are settled in a foreign currency other than the U.S. dollar. The Company does not enter into any foreign currency hedging agreements and is susceptible to gains and losses from foreign currency fluctuations. To date, the Company has not experienced significant gains or losses upon settling foreign contracts. At December 31, 2017, the Company had one customer with an accounts receivable balance totaling 10% or more of the Company’s total accounts receivable (10%) compared with three customers at December 31, 2016 (18%, 16% and 11%) and one customer at December 31, 2015 (10%). The Company had no customers with sales of 10% or more of the Company’s total revenue for the years ended December 31, 2017 and 2016, and one customer for the year ended December 31, 2015 (33%). Inventories, net Inventories are recorded at the lower of cost or net realizable value. Cost is determined using the average cost method. Parts from vendors are received and recorded as raw material. Once the raw materials are incorporated in the fabrication of the product, the related value of the component is recorded as work in progress (“WIP”). Direct and indirect labor and applicable overhead costs are also allocated and recorded to WIP inventory. Finished goods are comprised of completed products that are ready for customer shipment. The Company periodically evaluates the carrying value of inventory on hand for potential excess amounts over sales and forecasted demand. Excess and obsolete inventories identified, if any, are recorded as an inventory impairment charge to the consolidated statements of operations and comprehensive loss. Our estimate of write downs for excess and obsolete inventory is based on a detailed analysis of on-hand inventory and purchase commitments in excess of forecasted demand. Subsequent disposals of inventories are recorded as a reduction of an inventory reserve. Property and Equipment, net Property and equipment are stated at cost less accumulated depreciation and are depreciated on a straight-line basis over the estimated useful lives of the assets, generally ranging from three to thirteen years. Leasehold improvements are amortized over the shorter of the estimated useful life or the related term of the lease. The costs of repairs and maintenance are expensed when incurred, while expenditures for refurbishments and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. When assets are retired or sold, the asset cost and related accumulated depreciation or amortization are removed from the accompanying consolidated balance sheets, with any gain or loss reflected in the accompanying consolidated statements of operations and comprehensive loss. The Company has evaluated its lease obligations and does not have any material asset retirement obligations. Impairment of Long-Lived Assets The Company assesses the impairment of long-lived assets whenever events or changes in circumstances indicate that their carrying value may not be recoverable from the estimated future cash flows expected to result from the Company’s use or eventual disposition. If estimates of future undiscounted net cash flows are insufficient to recover the carrying value of the assets, the Company will record an impairment loss in the amount by which the carrying value of the assets exceeds the fair value. If the assets are determined to be recoverable, but the useful lives are shorter than originally estimated, the Company will depreciate or amortize the net book value of the assets over the newly determined remaining useful lives. None of the Company’s property and equipment or intangible assets were impaired as of December 31, 2017 and 2016. No impairment loss has been recognized in the years ended December 31, 2017, 2016, and 2015. Goodwill The Company records goodwill when the purchase price of an acquisition exceeds the fair value of the net tangible and identified intangible assets acquired. We perform an annual impairment assessment in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, which includes evaluating qualitative and quantitative factors to assess the likelihood of an impairment of goodwill. We perform impairment tests using a fair value approach when necessary. None of the Company’s goodwill was impaired as of December 31, 2017 and 2016. No impairment loss has been recognized in the years ended December 31, 2017, 2016, and 2015. For further discussion of goodwill, see Note 4 Equipois Acquisition. 63 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) Warrants Issued in Connection with Financings We generally account for warrants issued in connection with debt and equity financings as a component of equity, unless the warrants include a conditional obligation to issue a variable number of shares or there is a deemed possibility that we may need to settle the warrants in cash. For warrants where there is a possibility that we may have to settle the warrants in cash, we estimate the fair value of the issued warrants as a liability at each reporting date and record changes in the estimated fair value as a non-cash gain or loss in the consolidated statements of operations and comprehensive loss. The fair values of these warrants have been determined using the Binomial Lattice model (“Lattice”) and the Black-Scholes Option Pricing model. The Lattice model provides for assumptions regarding volatility, call and put features and risk-free interest rates within the total period to maturity. The Black-Scholes Model requires inputs, such as the expected term of the warrants, expected volatility and risk-free interest rate. These values are subject to a significant degree of judgment on our part. The Company’s common stock price represents a significant input that affects the valuation of the warrants. Business Combinations We account for business combinations under the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations, where the total purchase price is allocated to the tangible and identified intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price is allocated using the information currently available, and may be adjusted, up to one-year from the acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. Contingent consideration, if any, is recorded at the acquisition date based upon the estimated fair value of the contingent payments. The fair value of the contingent consideration is re-measured each reporting period with any adjustments in fair value being recognized in loss from operations. The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill. Going Concern We assess our ability to continue as a going concern at every interim and annual period in accordance with ASC 205-40, Presentation of Financial Statements – Going Concern. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. Revenue Recognition The Company recognizes revenue when the four basic criteria of revenue recognition are met: • • • • Persuasive evidence of an arrangement exists. Customer contracts and purchase orders are generally used to determine the existence of an arrangement. The transfer of technology or products has been completed or services have been rendered. Evidence of shipment or customer acceptance, when applicable, is used to verify delivery. The sales price is fixed or determinable. The Company assesses whether the cost is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. Collectability is reasonably assured. The Company assesses collectability based primarily on the creditworthiness of the customer as determined by credit checks and analysis as well as the customer’s payment history. 64 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) When collaboration, other research arrangements, and product sales include multiple-element revenue arrangements, we account for these transactions by determining the elements, or deliverables, included in the arrangement and determining which deliverables are separable for accounting purposes. We consider delivered items to be separable if the delivered item(s) have stand-alone value to the customer and delivery or performance of the undelivered item is considered probable and substantially in control of the vendor. In the first quarter of 2018, we will adopt Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09, as amended, will replace most existing revenue recognition guidance in U.S. GAAP. (Refer to Note 2, Summary of Significant Accounting Policies and Estimates – Recent Accounting Pronouncements of our consolidated financial statements). Medical Device Revenue and Cost of Revenue Recognition The Company builds medical device robotic exoskeletons for sale and capitalizes into inventory materials, direct and indirect labor and overhead in connection with manufacture and assembly of these units. When the Company brought its first version medical device to market in 2012, the Company could not be certain as to the costs it would incur to support, maintain, service, and upgrade these early stage devices. Primarily for this reason, prior to January 1, 2016, the sale of a device, associated software, initial training, and extended support and maintenance were deemed as a single unit of accounting due to the uncertainty of the Company’s follow-up maintenance and upgrade expenses, which were forecast to extend over three years. Accordingly, the revenue from the sales of the device and associated cost of revenue were deferred at the time of shipment. Upon completion of training, the amount of the arrangements were recognized as revenue and cost of revenue over a three year period on a straight line basis, while all service expenses, whether or not covered by the Company’s original warranty, extended warranty contracts, or neither, were recognized as incurred. Effective January 1, 2016, the Company determined it had established (i) separate individual pricing for training, extended warranty coverage, and out-of-contract service or repairs, (ii) sufficient historical evidence of customer buying patterns for extended warranty and maintenance coverage, and (iii) a basis for estimating and recording warranty and service costs to allow the Company to separate its multiple element arrangements into two distinct units of accounting: (1) the device, associated software, original manufacturer warranty and training if required, and (2) extended support and maintenance. As a result, in the first quarter of 2016, the Company began to recognize revenue related to its sales transactions on a multiple element approach in which revenue is recognized upon the delivery of the separate elements to the customer. Revenue relating to the undelivered elements is deferred using the relative selling price method, which allocates revenue to each element using the estimated selling prices for the deliverables when vendor-specific objective evidence or third-party evidence is not available. For sales on or after January 1, 2016, revenue and associated cost of revenue of medical devices is recognized when delivered, or training has been completed, if required. Revenue for extended maintenance and support agreements is recognized on a straight line basis over the contractual term of the agreement, which typically ranges from one to four years. As a result of this change, the Company recognized medical device revenue previously deferred at December 31, 2015 of $6,517 and associated cost of revenue of $4,159, resulting in additional gross profit, reduction in net loss from operations, and reduction of net loss applicable to common stockholders of $2,358, or $0.13 per share, in its results of operations for the year ended December 31, 2016. In addition, the Company recorded $212 for warranty expenses and a one-time charge of $911 for a planned preventative maintenance and upgrade program associated with the devices it had sold prior to 2016 in the same time period. Industrial Sales Revenue and Cost of Revenue The Company builds industrial exoskeletons for sale and capitalizes into inventory materials, direct and indirect labor, and overhead in connection with the manufacture and assembly of these units. No right of return exists on sales of industrial exoskeletons. We assess collectability at the time of the sale and if collectability is not reasonably assured, the sale is deferred and not recognized until collectability is probable or payment is received. Typically, where product is produced and sold in the same country, title and risk of ownership transfer when the product is shipped. Products that are exported from a country for sale typically pass title and risk of ownership at the border of the destination country. Because our industrial products are produced in the U.S., title and risk of ownership generally transfer when the product is shipped, if shipped to a customer in the U.S. If we sell products to customers outside the U.S., title and risk of ownership is generally transferred at the border of the destination country. 65 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) Engineering Services Revenue and Cost of Revenue Collaborative arrangements typically consist of cost reimbursements for specific engineering and development spending, and future product royalty payments. Cost reimbursements for engineering and development spending are recognized as the related project labor hours are incurred in relation to all labor hours and when collectability is reasonably assured. Amounts received in advance are recorded as deferred revenue until the technology is transferred, services are rendered, or milestones are reached. Product royalty payments are recorded when earned under the arrangement. Government grants, which support the Company’s research efforts in specific projects, generally provide for reimbursement of approved costs as defined in the notices of grant awards. Grant revenue is recognized as the associated project labor hours are incurred in relation to total labor hours. There are some grants, such as the National Science Foundation grants, of which the Company draws upon and spends based on budgets preapproved by the grantor. The cost of engineering services revenue includes payroll and benefits, subcontractor expenses and materials. All costs related to engineering services are expensed as incurred and reported as cost of revenue. Deferred Revenues In connection with the Company’s medical device sales and engineering services, the Company often receives cash payments before its earnings process is complete. In these instances, the Company records the payments as customer deposits until a device is shipped to the customer, or as customer advances in the case of research services until the earnings process is achieved. In both cases, the cash received is recorded as a component of deferred revenue. Deferred revenues consisted of the following: Deferred extended maintenance and support Deferred rental income Customer deposits and advances Deferred medical device revenues Total deferred revenues Less current portion Deferred revenues, non-current Research and Development December 31, 2017 2016 $ $ 1,763 $ 73 52 31 1,919 (1,103) 816 $ 1,523 60 47 - 1,630 (825) 805 Research and development costs consist of costs incurred for internal research and development activities. These costs primarily include salaries and other personnel-related expenses, contractor fees, facility costs, supplies, and depreciation of equipment associated with the design and development of new products prior to the establishment of their technological feasibility. Such costs are expensed as incurred. 66 Table of Contents Advertising Costs Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) Advertising costs are recorded in sales and marketing expense as incurred. Advertising expense was $160, $108, and $25 for the years ended December 31, 2017, 2016, and 2015, respectively. Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, income tax expense or benefit is recognized for the amount of taxes payable or refundable for the current year and for deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company's consolidated financial statements or tax returns. The Company accounts for any income tax contingencies in accordance with accounting guidance for income taxes. The measurement of current and deferred tax assets and liabilities is based on provisions of currently enacted tax laws. The effects of any future changes in tax laws or rates have not been considered. For the preparation of the Company's consolidated financial statements included herein, the Company estimates its income taxes and tax contingencies in each of the tax jurisdictions in which it operates prior to the completion and filing of its tax returns. This process involves estimating actual current tax expense together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in net deferred tax assets and liabilities. The Company must then assess the likelihood that the deferred tax assets will be realizable, and to the extent they believe that realizability is not likely, the Company must establish a valuation allowance. In assessing the need for any additional valuation allowance, the Company considers all the evidence available to it, both positive and negative, including historical levels of income, legislative developments, expectations and risks associated with estimates of future taxable income, and ongoing prudent and feasible tax planning strategies. Stock-based Compensation The Company measures stock-based compensation expense for certain stock-based awards made to employees and directors based on the estimated fair value of the award on the date of grant using the Black-Scholes option pricing model and recognizes the fair value on a straight-line basis over the requisite service periods of the awards. Stock-based awards made to non-employees are measured and recognized based on the estimated fair value on the vesting date and are re-measured at each reporting period. The Company’s determination of the fair value of stock options on the date of grant using the Black-Scholes option pricing model is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. Because there is insufficient information available to estimate the expected term of the stock- based awards, the Company adopted the simplified method of estimating the expected term pursuant to SEC Staff Accounting Bulletin Topic 14. On this basis, the Company estimated the expected term of options granted by taking the average of the vesting term and the contractual term of the option. The Company has, from time to time, modified the terms of its stock options to employees. The Company accounts for the incremental increase in the fair value over the original award on the date of the modification as an expense for vested awards or over the remaining service (vesting) period for unvested awards. The incremental compensation cost is the excess of the fair value of the modified award on the date of modification over the fair value of the original award immediately before the modification. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The updated standard will replace most existing revenue recognition guidance in U.S. GAAP. The new standard introduces a five-step process to be followed in determining the amount and timing of revenue recognition. It also provides guidance on accounting for costs incurred to obtain or fulfill contracts with customers, and establishes disclosure requirements which are more extensive than those required under existing U.S. GAAP. The FASB has issued numerous amendments to ASU 2014-09 from August 2015 through January 2018, which provide supplemental and clarifying guidance, as well as amend the effective date of the new standard. ASU 2014-09, as amended, is effective for the Company in the first quarter of 2018. The standard permits the use of either the retrospective or modified retrospective (cumulative effect) transition method. The Company adopted the new standard using the modified retrospective transition method. Although we have not fully completed our analysis of this new revenue recognition guidance, we do not believe that such guidance will materially impact the aggregate amount and timing of our revenue recognition subsequent to adoption, nor do we expect a significant cumulative adjustment to our consolidated balance sheet as of January 1, 2018. However, the Company will provide enhanced revenue recognition disclosures as required by the new standard. 67 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) which will require lessees to recognize assets and liabilities for leases with lease terms of more than 12 months. For finance leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize interest on the lease liability separately from amortization of the right-of-use asset in the statement of comprehensive income, and (3) classify repayments of the principal portion of the lease liability within financing activities and payments of interest on the lease liability and variable lease payments within operating activities in the statement of cash flows. For operating leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2018. The Company is evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminated the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities are required to record an impairment charge based on the excess of the carrying amount over its fair value. The new standard will be effective for the Company beginning January 1, 2020 and early adoption is permitted. The Company does not expect the impact of adopting ASU 2017-04 to be material on its consolidated financial statements and related disclosures. In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (ASU 2017-09). The FASB issued the update to provide clarity and reduce the cost and complexity when applying the guidance in Topic 718. The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for the Company in the first quarter of 2018. The Company does not expect the impact of adopting ASU 2017-09 to be material on its consolidated financial statements and related disclosures. Accounting Pronouncements Adopted in 2017 In March 2016, the FASB issued ASU No. 2016-09 Compensation – Stock Compensation (Topic 718) Improvements to Employee Share- Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for share-based payment award transactions for public companies, including: (1) income tax consequences, (2) classification of awards as either equity or liabilities, and (3) classification on the statement of cash flows. The amendments in this update are effective for annual periods beginning after December 15, 2016. Effective January 1, 2017, the Company adopted ASU 2016-09 and elected to change its accounting policy to account for forfeitures as they occur to more closely align compensation expense to services provided. The change was applied on a modified retrospective basis with a cumulative effect adjustment to retained earnings of $171 as of January 1, 2017. 68 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) 3. Net Loss Per Share of Common Stock Basic net loss per share of common stock is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed using the weighted average number of common stock, adjusted to include conversion of certain stock options and warrants for common stock and release of common stock in connection with restricted stock units during the period, as follows: Numerator: Net loss applicable to common stockholders Adjustment for gain on fair value of warrant liability Adjusted net loss used for dilution calculation $ $ (29,122) $ - (29,122) $ (33,815) $ (4,286) (38,101) $ (24,245) (2,505) (26,750) Years ended December 31, 2016(1) 2017 2015 Denominator Weighted-average number of shares outstanding Effect of potential dilutive shares Dilutive weighted-average number of shares outstanding Net loss per share applicable to common stockholders Basic Diluted 35,609 - 35,609 18,126 496 18,622 14,606 3 14,609 $ $ (0.82) $ (0.82) $ (1.87) $ (2.05) $ (1.66) (1.83) (1) Recognition of previously deferred revenue and cost of goods in the year ended December 31, 2016 reduced net loss applicable to common stockholders by $2,358, or $0.13 per share (see Note 2. Basis of Presentation and Summary of Significant Accounting Policies and Estimates – Medical Device Revenue and Cost of Revenue Recognition). The following potential dilutive securities were excluded from the computation of diluted net loss per share because including them would have been anti-dilutive: Options to purchase common stock Restricted stock units Warrants for common stock Common stock issuable upon conversion of preferred shares Total common stock equivalents 4. Equipois Acquisition Years ended December 31, 2016 2017 2015 3,156 616 3,396 - 7,168 2,477 - 1,963 - 4,440 1,963 - 1,963 1,876 5,802 On December 1, 2015, the Company acquired substantially all of the assets of Equipois, LLC, a New Hampshire limited liability company (“Equipois”), for an initial payment of approximately $1.1 million of the Company’s common stock pursuant to an asset purchase agreement among the Company, Ekso Bionics, Inc., Equipois and Allard Nazarian Group, Inc. (the “Asset Purchase Agreement”). The Company will make additional payments in shares of the Company’s common stock or cash based in part upon the achievement of certain financial targets for the period from January 1, 2016 through December 31, 2018. The Company accounted for the acquisition as a business combination by applying the acquisition method, and accordingly, the purchase price of $1,839 was allocated to the assets assumed based on their fair values at the acquisition date. The excess of the purchase price over the assets of $189 was recorded as goodwill. The goodwill recognized is attributed primarily to expected synergies of Equipois with the Company. From the acquisition date and as of December 31, 2017, there were no changes in the recognized amounts of goodwill resulting from the acquisition. For the year ended December 31, 2015, the Company did not recognize any revenue related to the Equipois acquisition. 69 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) The acquired assets consist of mechanical balance and support arms technologies, including the rights to the zeroG® and X-Ar® products. The acquired assets were integral to the Equipois business and include patents, trademarks and other intellectual property rights as well as certain tools and product designs and specifications. The Company also assumed the rights and obligations of Equipois under certain intellectual property license agreements. The Company did not assume any other obligations of Equipois. The total purchase price is summarized as follows: Stock consideration (112 shares) Estimated contingent consideration Total purchase price Amount $ 1,071 768 $ 1,839 The fair value of the 112 shares of common stock issued was determined based on the closing market price of the Company’s common shares on the acquisition date. In connection with the acquisition, the parties entered into a supply agreement pursuant to which Equipois supplied products to the Company during a post-closing transition period expiring December 31, 2016 (the “Supply Agreement”), and a reseller agreement pursuant to which Equipois may purchase and resell the products to certain current Equipois customers for a three-year term (the “Reseller Agreement”). Under the Supply Agreement, the Company was obligated to make a minimum purchase of $157 and a maximum purchase of $521. The fair value of the contingent consideration resulting from the Supply Agreement and Reseller Agreement was recorded at the time of acquisition. The Supply Agreement required the Company to pay $500 in additional shares of the Company’s common stock on December 31, 2016. In addition, the Reseller Agreement requires the Company to pay an annual contingent consideration payment of between $125 and $375 in shares of the Company’s common stock if the Company and Equipois meet certain product sales targets for each of the calendar years 2016, 2017 and 2018. Upon the termination of the Reseller Agreement by the Company without cause, the Company will pay to Equipois a final contingent consideration payment, payable in shares of the Company’s common stock, such that the total consideration received by Equipois under the Asset Purchase Agreement, including the shares issued upon closing, the additional shares issued upon termination of the Supply Agreement and the annual contingent consideration payments are not less than the sum of (a) 7.5 multiplied by 10% of specified product revenues of Equipois during the preceding four complete quarters, plus (b) 7.5 multiplied by 5% of specified product revenues of the Company during the preceding four complete quarters. The Asset Purchase Agreement also provided for the election of a buyout payment by either the Company or Equipois which is payable in shares of the Company’s common stock. The buyout payment provision expired on November 30, 2017. The contingent consideration is valued using the Probability Weighted Value Analysis which considered performance based contingent payments for both the supply and sales functions of the Company, and both buyer and seller options. Any changes in the fair value of this contingent consideration liability are recognized in loss from operations in the period of the change. Multiple forecasted scenarios were evaluated which include (i) a minimum payment case, (ii) an expected payment case and (iii) a maximum payment case. The Company determined the potential deferred payment cash flows of Equipois and the Company based on each scenario. The cash flow payments were converted to a present value using a discount rate of 15% based on the Company’s weighted average cost of capital. Finally, the Company probability weighted each scenario. The Company reviewed the assumptions used to value the contingent consideration from the date of acquisition to December 31, 2015, and noted no change in the initial estimated fair value of the contingent consideration. 70 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) For the year ended December 31, 2016, we reclassified $355 from the contingent consideration liability to accrued liabilities, to be paid in shares of common stock in the first quarter of 2017. On May 2, 2017, we issued 90 shares of our common stock to Equipois to satisfy the 2016 supply and sales earn-outs. Due to a decrease in our stock price between December 31, 2016 and the final payment calculation, we recorded a gain of $118 on the difference between the value of the consideration paid on May 2, 2017 of $237 and the value of the accrued liability at December 31, 2016 of $355, which was reclassified from the accrued liability. For the year ended December 31, 2017, the consideration payout calculated includes the $500 in additional shares of the Company’s common stock related to the Supply Agreement and the annual minimum of $125 under the Reseller Agreement. Due to the price floor of $7.00 per share in the number of shares of common stock issuable to satisfy the payment amount, we reclassified $38 from the contingent consideration liability to accrued liabilities as of December 31, 2017, to be paid in shares of common stock in the first quarter of 2018. The Company also recorded a non-cash gain on the change in fair value of the remaining contingent consideration liability of $137 in the consolidated statement of operations and comprehensive loss for the year ended December 31, 2017. The following table summarizes the fair values of the assets acquired as of the acquisition date: Fixed assets Intangible assets Total identifiable assets acquired Goodwill Net assets acquired Amount 40 $ 1,610 1,650 189 $ 1,839 The Company recorded $1,610 to intangible assets as of the acquisition date and is amortizing the value of the technology, customer relationships and trade name over an estimated useful life of 3 years. Amortization expense related to the acquired intangible assets was $535, $558 and $26 for the years ended December 31, 2017, 2016, and 2015, respectively, and was included as a component of operating expenses in the consolidated statement of operations and comprehensive loss. Of the $189 of goodwill, none was expected to be deductible for tax purposes. Acquired intangible assets as of December 31, 2017 were as follows: Developed technology Customer relationships Customer trade name Cost Accumulated Amortization Net $ $ 1,160 $ 70 380 1,610 $ (806) $ (49) (264) (1,119) $ Estimated Useful Life 3 yrs 3 yrs 3 yrs 354 21 116 491 The estimated future aggregate amortization expense is $491 for the year ended December 31, 2018. 5. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Three levels of inputs, of which the first two are considered observable and the last unobservable, may be used to measure fair value which are the following: 71 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) • • • Level 1—Quoted prices in active markets for identical assets or liabilities. The Company considers a market to be active when transactions for the asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The valuation of Level 3 investments requires the use of significant management judgments or estimation. The Company’s fair value hierarchies for its financial assets and liabilities which require fair value measurement on a recurring basis are as follows: December 31, 2017 Liabilities Warrant liability Contingent consideration liability Contingent success fee liability December 31, 2016 Liabilities Warrant liability Contingent consideration liability Contingent success fee liability Total Level 1 Level 2 Level 3 $ $ $ $ $ $ 1,648 $ 42 $ 39 $ 3,546 $ 217 $ 116 $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ 1,648 42 39 3,546 217 116 During the years ended December 31, 2017 and 2016, there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value on a recurring basis and the valuation techniques used did not change compared to the Company’s established practice. The following table sets forth a summary of the changes in the fair value of Company’s Level 3 financial liabilities during the year ended December 31, 2017, which were measured at fair value on a recurring basis: Warrant Liability Contingent Consideration Liability Contingent Success Fee Liability Balance at December 31, 2016 $ Initial fair value of April 2017 Warrants Repurchase of April 2017 Warrants Loss on repurchase of April 2017 Warrants Gain on revaluation of 2015 and April 2017 Warrants Reclassification of warrant liability to equity upon exercise of warrants Gain on revaluation Reclassification to accrued liabilities Balance at December 31, 2017 3,546 $ 3,301 (2,296) 1,067 (3,909) (61) - - $ 1,648 $ 217 $ - - - (255) 80 42 $ 116 - - - (77) - 39 The 2015 Warrants were valued at $3,546 at December 31, 2016, and the initial value of the April 2017 Warrants was $3,301. Due to a decrease in the Company’s common stock price from December 31, 2016 to December 31, 2017 the fair value of the 2015 Warrants decreased by $1,837 and the fair value of the April 2017 Warrants decreased by $2,072 from the issuance date to the repurchase date, which resulted in a total non-cash gain of $3,909 recorded in the Company’s consolidated statements of operations and comprehensive loss for the year. See Note 13 in the notes to our consolidated financial statements under the caption Capitalization and Equity Structure – 2015 Warrants for a description of the warrants, including the method and inputs used to estimate their fair value. 72 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) We measure our contingent consideration liability at fair value at each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. We use a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are sales projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings. The amount settled that is less than or equal to the liability on the acquisition date is reflected as non-cash financing activities in our consolidated statements of cash flows. Any amount settled in excess of the liability on the acquisition date is reflected as non-cash operating activities. Any changes in the estimated fair value of our contingent consideration liabilities related to the time component of the present value calculation are reported in interest expense. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in our statements of operations and comprehensive loss. 6.

During the year ended December 31, 2016, the Company determined it had sufficient historical experience of warranty costs to estimate future warranty costs for devices sold. As a result, and beginning during the year ended December 31, 2016, a liability for the estimated cost of product warranty is established at the time revenue is recognized based on the historical experience of known product failure rates and expected material and labor costs to provide warranty services. From time to time, specific additional warranty accruals may be made if unforeseen technical problems arise. Alternatively, if estimates are determined to be greater than the actual amounts necessary, a portion of the liability may be reversed in future periods. Warranty costs are reflected in the consolidated statements of operations and comprehensive loss as a component of costs of revenue. In addition, in the year ended December 31, 2016, the Company recorded in its consolidated statements of operations and comprehensive loss a one-time charge of $911 for a preventative maintenance and improvement program for devices sold prior to 2016 to bring the devices to second generation GT-level functionality. In the year ended December 31, 2017, the Company reassessed the number of devices still needing to be brought to second generation GT-level functionality and adjusted the maintenance accrual accordingly. 2017 Balance at December 31, 2016 Additions for estimated future expense Incurred costs Adjustment from remeasurement Balance at December 31, 2017 Current portion Long-term portion Total Balance at December 31, 2015 Additions for estimated future expense Incurred costs Balance at December 31, 2016 Current portion Long-term portion Total Maintenance Warranty 483 $ $ - (229) (133) 121 $ $ 204 $ 207 (179) 232 $ 121 - 121 $ 232 - 232 $ $ 2016 Maintenance Warranty $ - $ 911 (428) 483 $ - $ 430 (226) 204 $ 483 - 483 $ 203 1 204 $ $ $ 74 Total 687 207 (408) (133) 353 353 - 353 Total - 1,341 (654) 687 686 1 687 Table of Contents 9. Long-Term Debt Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) On December 30, 2016, the Company entered into a loan agreement and received $7,000 that bears interest on the outstanding daily balance at a floating per annum rate equal to the 30-day U.S. LIBOR plus 5.41%. The loan agreement created a first priority security interest with respect to substantially all assets of the Company, including proceeds of intellectual property, but expressly excluding intellectual property itself. The Company is required to pay accrued interest on the current loan on the first day of each month through and including January 1, 2018. Commencing on February 1, 2018, the Company is required to make equal monthly payments of principal, together with accrued and unpaid interest. The principal balance of the current loan amortizes ratably over 36 months, and matures on January 1, 2021, at which time all unpaid principal and accrued and unpaid interest shall be due and payable in full. In addition, a final payment of $245 will be due on the maturity date, of which $97 has accreted as of December 31, 2017, to be paid in 2021 and is included as a component of note payable on the Company’s consolidated balance sheets. In December 2016, and pursuant to the loan agreement, the Company entered into a success fee agreement with the lender under which the Company agreed to pay the lender a $250 success fee upon the first to occur of any of the following events: (a) a sale or other disposition by the Company of all or substantially all of its assets; (b) a merger or consolidation of the Company into or with another person or entity, where the holders of the Company’s outstanding voting equity securities immediately prior to such merger or consolidation hold less than a majority of the issued and outstanding voting equity securities of the successor or surviving person or entity immediately following the consummation of such merger or consolidation; or (c) the closing price per share for the Company’s common stock being $8.00 or more for five successive business days. The estimated fair value of the success fee was determined using the Binomial Lattice Model and was recorded as a discount to the debt obligation. The fair value of the contingent success fee is re-measured each reporting period with any adjustments in fair value being recognized in the consolidated statements of operations and comprehensive loss. The success fee is classified as a liability on the consolidated balance sheets. At December 31, 2017, the fair value of the contingent success fee liability was $39. The loan agreement includes a liquidity covenant requiring that the Company maintain unrestricted cash and cash equivalents in accounts of the lender or subject to control agreements in favor of the lender in an amount equal to at least three months of “Monthly Cash Burn,” which is the Company’s average monthly net income (loss) for the trailing six-month period plus certain expenses and plus the average monthly principal due and payable on interest-bearing liabilities in the immediately succeeding three-month period. Such amount was determined to be $5,472 as of December 31, 2017, the most current determination, with the amount subject to change on a month-to-month basis. Pursuant to the Restructuring and in anticipation of the Rights Offering, the lender and the Company executed an amendment to the loan agreement on August 3, 2017, which suspended the minimum liquidity requirement until September 16, 2017. At December 31, 2017, with cash on hand of $27,813, the Company was compliant with this liquidity covenant and all other covenants. The final payment fee, debt issuance costs, and the initial fair value of the success fee combined with the stated interest resulted in an effective interest rate of 9.05% for the year ended December 31, 2017. The final payment fee, initial fair value of the success fee and debt issuance costs was and will be accreted, amortized and amortized, respectively, to interest expense using the effective interest method over the life of the loan. 75 Table of Contents Ekso Bionics Holdings, Inc.

Related Party Transactions On September 19, 2017, Ted Wang, Ph.D, was appointed to the Board of Directors and as a member of the Nominating and Governance Committee of the Board. Dr. Wang is the Chief Investment Officer and a founder of Puissance Capital Management LP. Dr. Wang was elected as a director following his nomination to the Board by Puissance Cross-Border Opportunities II LLC (“Puissance”), a stockholder of the Company and an affiliate of Puissance Capital Management LP. Puissance served as the committed investor in connection with the Company’s recently completed rights offering, in connection with which Puissance purchased 20,535 shares of the Company’s common stock for an aggregate purchase price of $20,535. Following completion of the rights offering, Puissance held approximately 34% of the Company’s issued and outstanding shares. Prior to Dr. Wang’s appointment to the Board, the Company entered into a one-year consulting agreement with Angel Pond Capital LLC (“Angel Pond”), an entity affiliated with Puissance. Angel Pond will assist the Company with strategic positioning in the Asia Pacific region, including the introduction to potential strategic and capital partner(s) and the development of strategic partnership(s) for the sale and manufacture of the Company’s products in that market. During the year ended December 31, 2017, the Company made aggregate payments of $2,150 to Angel Pond representing consulting services for one year. These fees are recognized ratably to expense over the one-year period. On March 11, 2018, Charles Li, Ph. D., was appointed to the Board of Directors and as a member of the Audit Committee. Dr. Li is a senior analyst at Puissance Capital Management. The Company has license agreements and various collaboration agreements (see Note 16, Commitments and Contingencies) with the Regents of the University of California, Berkeley (“UCB”) and for which UCB received shares of common stock of the Company. As of the second quarter of 2015, UCB no longer holds such shares. Total payments made to UCB for the years ended December 31, 2017, 2016, and 2015 were $66, $146, and $50, respectively. As of December 31, 2017 and 2016, amounts payable to UCB amounted to $31 and $23, respectively. 13. Capitalization and Equity Structure Reverse Stock Split After the close of the stock market on May 4, 2016, the Company effected a 1-for-7 reverse split of its common stock. As a result, all common stock share amounts included in this filing have been retroactively reduced by a factor of seven and all common stock per share amounts have been increased by a factor of seven, with the exception of our common stock par value. Amounts affected include common stock outstanding, including the issuance of new shares of common stock as a result of the conversion of preferred stock and the exercise of stock options and warrants. Summary The Company’s authorized capital stock at December 31, 2017 consisted of 141,429 shares of common stock and 10,000 shares of preferred stock. At December 31, 2017, 59,943 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding. 77 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) On October 30, 2017, the Board approved an amendment to the Company’s Articles of Incorporation to increase the number of shares of our common stock by 70,000 shares to 141,429 shares (the “Authorized Capital Amendment”), subject to the approval of such amendment by the stockholders. On December 21, 2017, a special meeting of the stockholders was convened (the “December Special Meeting”). In the definitive proxy statement dated November 24, 2017 filed by us with the SEC in respect of the December Special Meeting (the “November Proxy Statement”), the Board solicited the vote of the stockholders in favor of the Authorized Capital Amendment. The November Proxy Statement stated that broker non-votes in respect of the Authorized Capital Amendment would be counted as votes against the amendment. However, under relevant stock exchange rules, brokers had the discretionary authority to vote any shares held in their name on behalf of a beneficial owner (“Broker Shares”), and in respect of which the broker did not receive voting instruction from the beneficial owner, in favor of the Authorized Capital Amendment. As such, brokers voted approximately 17,628 Broker Shares, in respect of which the brokers had not received voting instructions from the beneficial owners of such shares, in favor of the Authorized Capital Amendment at the December Special Meeting. Accordingly, after taking into account such Broker Shares, the Authorized Capital Amendment was approved by the stockholders at the December Special Meeting. However, as disclosed in more detail under Item 3 to this Annual Report on Form 10-K, some stockholders of the Company have claimed that the disclosure in the November Proxy Statement in connection with the effect on the Authorized Capital Amendment of beneficial owners not providing voting instructions in respect of their Broker Shares was incorrect. Accordingly, stockholders will be asked to vote again on the Authorized Capital Amendment at our 2018 Annual Meeting of Shareholders. Further information about such vote will be provided in the Company’s Proxy Statement relating to its 2018 Annual Meeting of Shareholders, to be filed with the SEC within 120 days of December 31, 2017. Common Stock The holders of outstanding shares of common stock are entitled to receive dividends out of assets or funds legally available for the payment of dividends at such times and in such amounts as the Board of Directors from time to time may determine. Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. There is no cumulative voting for the election of directors. The common stock is not entitled to pre-emptive rights and is not subject to conversion or redemption. Upon liquidation, dissolution or winding up of the Company, the assets legally available for distribution to stockholders are distributable ratably among the holders of the common stock after payment of liquidation preferences, if any, on any outstanding payment of other claims of creditors. Each outstanding share of common stock is duly and validly issued, fully paid, and non-assessable. April 2017 Common Stock Offering In April 2017, the Company sold in a registered direct offering an aggregate of 3,732 shares of its common stock, par value $0.001 per share, and warrants to purchase 1,866 shares of common stock (“April 2017 Warrants”). The aggregate net proceeds of the transaction were approximately $10,919. August 2017 Rights Offering In August of 2017, the Company commenced a $34,000 rights offering (the “Rights Offering”) to its existing stockholders and certain warrant holders of the Company on the record date of August 10, 2017. The subscription price was $1.00 per share and each subscription right provided 1.1608 shares of the Company’s common stock plus an oversubscription right, subject to availability. Concurrent with the rights offering, the Company entered into a purchase agreement (the “Backstop Investment Agreement”) with Puissance Cross-Border Opportunities II LLC (the “Backstop Investor”). The Backstop Investment Agreement contemplated the purchase of any unsubscribed shares from the Rights Offering under the same terms, subject to a cap of 40% of the Company’s total outstanding shares. Under the Backstop Investment Agreement, 20,534,898 shares of our common stock (“Puissance Shares”) were issued to the Backstop Investor. The Puissance Shares were issued in an unregistered offering, and were subsequently registered by the Company for resale to the public pursuant to a registration rights agreement entered into with the Backstop Investor. In connection with the rights offering, the Company entered into a Warrant Repurchase and Amendment Agreement (“Repurchase Agreement”) with all of the holders of the April 2017 Warrants. Under the Repurchase Agreement, the Company agreed to repurchase the April 2017 Warrants from each holder at a price of $1.23 per underlying share. The Company’s obligation to repurchase the warrants was subject to the warrant holder’s participation in the Rights Offering. The Repurchase Agreement also permitted the holders of the April 2017 Warrants to use all or a portion of the consideration received as a result of the Company’s repurchase of the April 2017 Warrants to pay the subscription price for the exercise of their subscription rights in the Rights Offering. Upon the closing of the Rights Offering the Company repurchased warrants exercisable for 1,866 shares and applied consideration of $2,245 to the subscribed shares in the Rights Offering. 78 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) The Company sold an aggregate of 13,465 shares of its common stock to existing stockholders and certain warrant holders in the Rights Offering for gross proceeds of $13,465, which after deducting expenses, totaling approximately $286, resulted in net proceeds of $13,179 from the Rights Offering; and sold the Puissance Shares to the Backstop Investor in a private placement in conjunction with the Rights Offering for gross proceeds of $20,535. The Puissance Shares were subsequently registered by the Company for resale to the public pursuant to a registration rights agreement entered into with the Backstop Investor. Of the $286 in direct issuance costs, warrants with a fair value of $131 have been issued to an information agent. The warrants are classified as equity in the statement of stockholders’ equity. The Company intends to use the proceeds of the offering to broaden its footprint in Asia, support research, development and commercialization activities, and for working capital. 2016 Common Stock Offering On August 12, 2016, the Company issued 3,750 shares of common stock at a price to the public of $4.00, resulting in proceeds to the Company of $13,696, net of the underwriting discount and issuance costs. On August 17, 2016, the Company issued an additional 267 shares of common stock as a result of the partial exercise of the underwriters’ overallotment option for additional proceeds of $998, net of the underwriting discount. The Company plans to use the proceeds from this offering for its operations. As discussed below, the Series A Convertible Preferred Stock issued in December 2015 (the “Preferred Shares”) and the common stock warrants issued in December 2015 (the “2015 Warrants”) included price-based anti-dilution provisions providing for the adjustment of the conversion price and the exercise price, as applicable, in the event the Company sells common stock or common stock equivalents (subject to exceptions for certain exempt issuances) at a price lower than the then-conversion price of the Preferred Shares or the then-exercise price of the 2015 Warrants. Because the sale price to the underwriters of the common stock in the August 2016 common stock offering was less than the then-conversion price of the Preferred Shares and the then-exercise price of the 2015 Warrants, there was an anti-dilution adjustment to the number of shares of common stock issuable upon conversion of the Preferred Shares and the exercise price of the 2015 Warrants was reduced, as discussed in more detail below. Preferred Stock The Company may issue shares of preferred stock from time to time in one or more series, each of which will have such distinctive designation or title as shall be determined by its Board of Directors and will have such voting powers, full or limited, or no voting powers, and such preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions thereof, as shall be stated in such resolution or resolutions providing for the issue of such class or series of preferred stock as may be adopted from time to time by the Board of Directors. Convertible Preferred Stock On December 23, 2015, the Company entered into an agreement to issue 15 Preferred Shares and 2015 Warrants to purchase 2,122 shares of the Company’s common stock for which the Company received gross proceeds of $15,000 (the “Financing”). After deducting transaction costs, the Company received $13,906 without considering $173 of related expenses paid in 2016. Each Preferred Share was initially convertible into 0.141 shares of common stock (after giving effect to the reverse stock split) at any time at the election of the investor. At the date of the Financing, because the effective conversion rate of the Preferred Shares was less than the market value of the Company’s common stock a beneficial conversion feature of $3,300 was recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the Preferred Shares were perpetual, at December 23, 2015, the Company fully amortized the discount related to the beneficial conversion feature on the Preferred Shares to additional paid in capital to record a deemed dividend, and reflected this amount as a preferred deemed dividend in the consolidated statement of operations and comprehensive loss. 79 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) Conversion of the Preferred Shares triggers the amortization of the discount related to a beneficial conversion feature and to the 2015 Warrants. The terms of the Preferred Shares and 2015 Warrants included price-based anti-dilution provisions providing for the adjustment of the conversion price and the exercise price, as applicable, in the event the Company sold common stock or common stock equivalents (subject to exceptions for certain exempt issuances) at a price lower than the then-conversion price of the Preferred Shares or the then- exercise price of the 2015 Warrants. Because the sale price to the underwriters of the common stock in the August 2016 common stock offering was less than the conversion price of the Preferred Shares at the time, the conversion price of the Preferred Shares was adjusted downwards from $7.07 to $3.74 per share, which resulted in each outstanding Preferred Share becoming convertible into 0.267 shares of common stock at any time at the election of the investor. As a result, the 3 Preferred Shares then outstanding became convertible, for no additional consideration, into a total of 921 shares of the Company’s common stock. At December 31, 2015, 13 Preferred Shares were outstanding. As of December 31, 2017 and 2016, no Preferred Shares remained outstanding and the warrant discount was fully amortized. During the year ended December 31, 2016, 10 Preferred Shares were converted into 1,389 shares of common stock at a conversion price of $7.07 per share, and 3 Preferred Shares were converted into 921 shares of common stock at a conversion price of $3.74 per share. The conversions triggered the amortization of the warrant discount of $10,345 for the year ended December 31, 2016, which were recorded in the consolidated statements of operations and comprehensive loss as non-cash preferred deemed dividends. During the year ended December 31, 2015, 2 Preferred Shares were converted into common stock at a conversion price of $7.07 per share. The conversion triggered the amortization of the warrant discount of $1,355, which was also accounted for as a preferred deemed dividend. Warrants Warrant share activity for the year ended December 31, 2017 was as follows: Source $ Information Agent Warrants $ April 2017 Warrants 2015 Warrants $ 2014 PPO and Merger warrants $ Placement agent warrants $ Bridge warrants $ PPO warrants $ Pre 2014 warrants Exercise Price 1.50 4.10 3.74 7.00 7.00 14.00 9.66 Term (Years) 3 5 5 5 3 5 9-10 December 31, 2016 Issued Repurchased(1) Expired Exercised - - 1,634 426 371 1,078 88 3,597 200 1,866 - - - - - 2,066 - (1,866) - - - - - (1,866) - - - - (371) - - (371) - - (30) - - - - (30) December 31, 2017 200 - 1,604 426 - 1,078 88 3,396 (1) The April 2017 Warrants were repurchased at a price of $1.23 per underlying share, as a result of the August 2017 Rights Offering. Information Agent Warrants In September 2017, in connection with the Rights Offering in August of 2017, the Company issued warrants to purchase 200 shares of the Company’s common stock with an exercise price of $1.50 to an information agent (the “Information Agent Warrants”). The Information Agent Warrants became exercisable immediately upon issuance. These warrants were recorded in stockholders’ equity on the Company’s consolidated balance sheet. 80 Table of Contents April 2017 Warrants Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) In April 2017, the Company issued the April 2017 Warrants to purchase 1,866 shares of the Company’s common stock with an exercise price of $4.10 per share. The April 2017 Warrants were to become exercisable six months following the issuance date and were to expire five years from the date they became exercisable. The April 2017 Warrants contained a put-option provision. Under this provision, while the April 2017 Warrants were outstanding, if the Company entered into a Fundamental Transaction, defined as a merger, consolidation or similar transaction, the Company or any successor entity would, at the option of each warrant holder, exercisable at any time within 30 days after the consummation of the Fundamental Transaction, purchase the warrant from the holder exercising such option by paying to the holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such holder’s warrant on the date of the consummation of the Fundamental Transaction. Because of this put-option provision, a portion of the proceeds from the sale of common stock in the registered direct offering was recorded as a warrant liability equal to the fair value of the warrants on the date of issuance and the April 2017 Warrants were marked to market at each reporting date. Issuance costs allocated to the April 2017 Warrants were $185 and were expensed as financing costs on the date of issuance. All of the issued and outstanding April 2017 warrants were repurchased at a price of $1.23 per underlying share, as a result of the August 2017 Rights Offering. As of December 31, 2017, none of the April 2017 Warrants remained outstanding. 2015 Warrants In connection with the December 2015 issuance of Preferred Shares discussed above, the Company issued warrants to purchase up to an aggregate of 2,122 shares of common stock (“2015 Warrants”). The 2015 Warrants have a 5 year term. Because the sale price to the underwriters of the common stock in the August 2016 offering was less than the exercise price of the 2015 Warrants at the time, the exercise price of the 2015 Warrants was adjusted downwards from $8.75 to $3.74 per share. The Warrants were valued at $11,700 on the date of the transaction. Due to the anti-dilution and put-option provisions discussed above, the Warrants were classified as a liability and are marked to market at each reporting date. Because the Warrants were recorded as a warrant liability, the portion of proceeds from the sale of the Preferred Shares that was recorded as equity was reduced accordingly. Equity issuance costs allocated to the Warrants were $487 and were expensed as financing costs at the date of issuance. The warrant liability is measured at fair value using certain estimated inputs, which are classified within Level 3 of the valuation hierarchy. These values are subject to a significant degree of judgment on our part. The Company’s common stock price represents a significant input that affects the valuation of the warrants. The Company estimated the fair value of the warrant liability on December 31, 2017 by using a Black-Scholes Option Pricing Model. The following assumptions were used in the Black-Scholes Option Pricing Model to measure the fair value of the 2015 Warrants as of December 31, 2017: Current share price Conversion price Risk-free interest rate Expected term (years) Volatility of stock December 31, 2017 2.13 $ 3.74 $ 1.98% 2.99 95% The Company estimated the fair value of the warrant liability on December 31, 2016 by using a Black-Scholes Option Pricing Model, as the anti-dilution provision was no longer in effect.

(the “Merger”). Concurrently with the closing of the Merger and in contemplation of the Merger, the Company held a closing of a private placement offering (the “PPO”) in which it issued warrants to purchase a total of 5,151 shares of common stock of which 4,329 were at an exercise price of $14.00 per share, and the balance of which were at an exercise price of $7.00 per share. Warrants to purchase preferred stock of Ekso Bionics outstanding prior to the Merger were converted into warrants to purchase 89 shares of common stock of the Company in connection with the Merger. As of December 31, 2017, there remained warrants to purchase 88 shares of the Company’s common stock outstanding, with the following terms: (1) expire on various dates from June 1, 2022 to August 30, 2023; (2) have an exercise price of $9.66 per share; and (3) at the option of the holder, may be exercised on a “cashless exercise” basis in which shares are retained to cover the exercise price based on the market value of the Company’s common stock on the date of exercise. 14. Stock-based Compensation 2014 Equity Incentive Plan In the first quarter of 2014, prior to the Merger, the Board of Directors and a majority of the stockholders adopted the 2014 Equity Incentive Plan (the “2014 Plan”) allowing for the issuance of 2,058 shares of common stock. On June 10, 2015, the 2014 Plan was amended and restated with approval by the stockholders to increase the maximum number of shares issuable by 1,656 shares to an aggregate of 3,714 shares of common stock. On June 20, 2017, the 2014 Plan was further amended with the approval by the stockholders to increase the maximum number of shares issuable under the 2014 Plan by 1,000 shares to an aggregate of 4,714 shares of common stock. October 30, 2017, the Board approved an amendment to the 2014 Plan to increase the maximum number of shares of common stock that may be issued under the 2014 Plan by 4,400 shares, from 4,714 to 9,114 shares (the “2014 Plan Amendment”) effective as of the time such amendment is approved by the stockholders. At the December Special Meeting, a proposal was submitted to be voted on by the stockholders to approve the 2014 Plan Amendment contingent on the approval by the stockholders of the Authorized Capital Amendment. The proposal was approved by the stockholders at the December Special Meeting, with approximately 25,205 shares voted for, 2,955 shares voted against, and 356 shares abstaining. However, since the proposal was contingent on the approval by the stockholders of the Authorized Capital Amendment, stockholders will be asked to vote again on the 2014 Plan Amendment at the 2018 Annual Meeting of Shareholders. Further information about such vote will be provided in the Company’s Proxy Statement relating to the Company’s 2018 Annual Meeting of Shareholders, to be filed with the SEC within 120 days of December 31, 2017. As of December 31, 2017, there were 4,838 shares available for future awards after taking into account the 2014 Plan Amendment. Under the terms of the 2014 Plan, the Board of Directors may award stock, options, or similar rights having either a fixed or variable price related to the fair market value of the shares and with an exercise or conversion privilege related to the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions or any other security with the value derived from the value of the shares. Such awards include stock options, restricted stock, restricted stock units, stock appreciation rights and dividend equivalent rights. 82 Table of Contents Ekso Bionics Holdings, Inc.

Incentive stock options granted to employees who, on the date of grant, own stock representing more than 10% of the voting power of all of the Company’s classes of stock, are granted at an exercise price of not less than 110% of the fair market value of the Company’s common stock. The maximum term of incentive stock options granted to employees who, on the date of grant, own stock possessing more than 10% of the voting power of all the Company’s classes of stock, may not exceed five years. The maximum term of an incentive stock option granted to any other participant may not exceed ten years. Subject to the limitations discussed above, the Board of Directors determines the term and exercise or purchase price of other awards granted under the 2014 Plan. To date, no incentive stock options have been granted. The Board of Directors also determines the terms and conditions of awards, including the vesting schedule and any forfeiture provisions. Options granted under the 2014 Plan may vest upon the passage of time, generally four years, or upon the attainment of certain performance criteria established by the Board of Directors. We may from time to time grant options to purchase common stock to non-employees for advisory and consulting services. At each measurement period we re- measure the fair value of these stock options using the Black-Scholes option pricing model and recognize expense ratably over the vesting period of each stock option award. Upon exercise of an option, it is the Company’s policy to issue new shares of common stock.

As of December 31, 2017, $599 of total unrecognized compensation expense related to employee RSUs was expected to be recognized over a weighted average period of 2.08 years. Of the 760 RSUs granted and 132 RSUs vested during the year ended December 31, 2017, 120 were granted and 115 vested to employees terminated in connection with the restructuring in May 2017. Compensation Expense Stock-based compensation is included in the consolidated statements of operations and comprehensive loss in general and administrative, research and development, or sales and marketing expenses, depending upon the nature of services provided. Stock-based compensation expense recorded for stock options and RSUs granted to employees and non-employees was as follows: Years Ended December 31, 2016 2015 2017 Sales and marketing Research and development General and administrative Restructuring Employee Stock Purchase Plan $ $ 485 $ 439 1,304 186 2,414 $ 677 $ 632 1,812 - 3,121 $ 579 414 738 - 1,731 In June 2017, the Company’s stockholders approved the Employee Stock Purchase Plan (the “2017 ESPP”). Under the 2017 ESPP, the Company reserved 500 shares of common stock for issuance, subject to adjustment in the event of a stock split, stock dividend, combination or reclassification or similar event. The 2017 ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 25% of their eligible compensation, subject to any plan limitations. The 2017 ESPP provides for six-month offering periods. At the end of each offering period, employees can purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last trading day of the offering period. As of December 31, 2017, enrollment in the plan had not yet commenced. 15. Income Taxes The domestic and foreign components of pre-tax loss for the years ended December 31, 2017, 2016, and 2015 were as follows: Domestic Foreign Loss before income taxes $ $ 85 Years Ended December 31, 2016 (21,458) $ (2,012) (23,470) $ 2017 (26,434) $ (2,688) (29,122) $ 2015 (19,918) 328 (19,590) Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) The Company had no current or deferred federal and state income tax expense or benefit for the years ended December 31, 2017, 2016, and 2015 because the Company generated net operating losses, and currently management does not believe it is more likely than not that the net operating losses will be realized. The Company’s non-U.S. tax obligation is primarily for business activities conducted through the United Kingdom for which taxes included in other expense, net for the years ended December 31, 2017, 2016, and 2015 were immaterial and accordingly, such amounts were excluded from the following tables. Income tax expense (benefit) for the years ended December 31, 2017, 2016, and 2015 differed from the amounts computed by applying the statutory federal income tax rate of 34% to pretax income (loss) as a result of the following: Federal tax at statutory rate State tax, net of federal tax effect R&D credit Change in valuation allowance Deferred tax impacts of the Tax Act Unrealized (gain) loss on warrant Foreign Other Total tax expense Years Ended December 31, 2016 2015 2017 34.0% - 1.2 18.9 (59.1) 3.1 (0.4) 2.3 -% 34.0% - 0.9 (40.8) - 6.2 (0.4) 0.3 -% 34.0% - 0.5 (38.4) - 4.3 0.5 0.1 -% The tax effects of temporary differences and related deferred tax assets and liabilities as of December 31, 2017 and 2016 were as follows: Deferred tax assets: Depreciation and other Net operating loss carryforwards Unused R& D tax credits Accruals & reserves Deferred Revenue Stock Compensation Other Deferred tax liabilities: Depreciation and other Prepaid expenses Less: Valuation allowance Net deferred tax asset (liability) December 31, 2017 2016 $ $ 242 $ 31,590 1,359 524 253 2,277 42 - (314) (35,973) - $ 61 35,647 872 951 246 2,430 86 - (168) (40,125) - The Company’s accounting for deferred taxes involves the evaluation of a number of factors concerning the realizability of the Company’s net deferred tax assets. The Company primarily considered such factors as the Company’s history of operating losses; the nature of the Company’s deferred tax assets and the timing, likelihood and amount, if any, of future taxable income during the periods in which those temporary differences and carryforwards become deductible. At present, the Company does not believe that it is more likely than not that the deferred tax assets will be realized; accordingly, a full valuation allowance was established and no deferred tax assets were shown in the accompanying balance sheets. The valuation allowance decreased by $4,153 during the year ended December 31, 2017 and increased by $10,827 during the year ended December 31, 2016. 86 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) In December 2017, the Tax Cuts and Jobs Act (the “Tax Act”), was signed into law. Among other provisions, the Tax Act reduces the federal statutory corporate tax rate from 35% to 21% for the Company’s tax years beginning in 2018. As a result, net deferred tax assets were re-measure, which resulted in a reduction of our deferred tax assets by $17,220, with a corresponding decrease to the valuation allowance of the same amount. We are in the process of assessing the impact of the international tax provisions provided for in the Tax Act that would apply for calendar years 2018 onwards. We are not, however, subject to the one-time mandatory transition tax. As of December 31, 2017 the Company had federal net operating loss carryforwards of $120,366. The Company also had federal research and development tax credit carryforwards of $1,294. The net operating loss and tax credit carryforwards will expire at various dates beginning in 2027, if not utilized. As of December 31, 2017, the Company had state net operating loss carryforwards of $84,466, which will begin to expire in 2017. The Company also had state research and development tax credit carryforwards of $655, which have no expiration. As of December 31, 2017, the Company had foreign net operating loss carryforwards of $4,701. The foreign net operating loss carryforwards do not expire. As of December 31, 2017, $1,749 of federal and $689 of state net operating loss is attributable to stock-based compensation deductions in excess of book expense. Upon adoption of ASU 2016-09-Compensation-Stock Compensation, the benefit of the tax deduction related to these options did not affect retained earnings due to the Company applying a full valuation allowance against the deferred tax assets, as is the Company’s current policy Utilization of the Company’s net operating losses and credit carryforwards may be subject to annual limitations in the event of a Section 382 ownership change. Such future limitations could result in the expiration of net operating losses and credit carryforwards before utilization as a result of such an ownership change. A reconciliation of the beginning and ending amount of unrecognized tax benefits were as follows: Balance at December 31, 2013 Increase of unrecognized tax benefits taken in prior years Increase of unrecognized tax benefits related to current year Balance at December 31, 2014 Decrease of unrecognized tax benefits taken in prior years Increase of unrecognized tax benefits related to current year Balance at December 31, 2015 Increase of unrecognized tax benefits taken in prior years Increase of unrecognized tax benefits related to current year Balance at December 31, 2016 Increase of unrecognized tax benefits taken in prior years Increase of unrecognized tax benefits related to current year Balance at December 31, 2017 $ $ 93 4 46 143 (19) 75 199 4 132 335 33 119 487 If the Company eventually is able to recognize these uncertain tax positions, the unrecognized tax benefits would not reduce the effective tax rate if the Company is applying a full valuation allowance against the deferred tax assets, as is the Company’s current policy. The Company had not incurred any material tax interest or penalties as of December 31, 2017. The Company does not anticipate any significant change within 12 months of this reporting date of its uncertain tax positions. The Company is subject to taxation in the United States, the United Kingdom, Germany, and various states jurisdictions. There are no other ongoing examinations by taxing authorities at this time. The Company’s tax years 2007 through 2017 will remain open for examination by the federal and state authorities for three and four years, respectively, from the date of utilization of any net operating loss credits. 87 Table of Contents 16. Contingencies and Commitments Contingencies Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) In the normal course of business, the Company is subject to various legal matters. In the opinion of management, the resolution of such matters will not have a material adverse effect on the Company’s consolidated financial statements. Material Contracts The Company enters into various license, research collaboration and development agreements which provide for payments to the Company for government grants, fees, cost reimbursements typically with a markup, technology transfer and license fees, and royalty payments on sales. The Company has two license agreements to maintain exclusive rights to patents. The Company is also required to pay 1% of net sales of products sold to entities other than the U.S. government. In the event of a sublicense, the Company will owe 21% of license fees and must pass through 1% of the sub-licensee’s net sales of products sold to entities other than the U.S. government. The agreements also stipulate minimum annual royalties of $50. In connection with acquisition of Equipois, the Company assumed the rights and obligations of Equipois under a license agreement with Garrett Brown, the developer of certain intellectual property related to mechanical balance and support arm technologies, which grants us an exclusive license with respect to the technology and patent rights for certain fields of use. Pursuant to the terms of the license agreement, the Company will be required to pay Mr. Brown a single-digit royalty on net receipts, subject to a $50 annual minimum royalty requirement. The following table summarizes our outstanding contractual obligations, including interest payments, as of December 31, 2017 and the effect those obligations are expected to have on our liquidity and cash flows in future periods: Term loan Facility operating lease Capital lease Total U.S. Food and Drug Administration Clearance Payments Due By Period Total Less than one year 1-3 Years 3-5 Years $ $ 8,039 $ 2,746 96 10,881 $ 2,565 $ 622 37 3,224 $ 5,033 $ 1,858 59 6,950 $ 441 266 - 707 On April 4, 2016, the Company received clearance from the U.S. Food and Drug Administration (“FDA”) to market its Ekso GT robotic exoskeleton for use in the treatment of individuals with hemiplegia due to stroke, individuals with spinal cord injuries at levels T4 to L5, and individuals with spinal cord injuries at levels of T3 to C7 (ASIA D), in accordance with the device’s labeling. On July 19, 2016, the Company received clearance from the FDA to expand/clarify the indications and labeling to expressly include individuals with hemiplegia due to stroke who have upper extremity function of at least 4/5 in only one arm. The Company’s prior cleared indications for use statement required that individuals with hemiplegia due to stroke have upper extremity function of at least 4/5 in both arms. 88 Table of Contents Ekso Bionics Holdings, Inc. Notes to Consolidated Financial Statements (In thousands, except per share amounts) The Company believes that prior to April 4, 2016, the Company’s Ekso GT robotic exoskeleton had been appropriately marketed in the United States as a Class I 510(k) exempt Powered Exercise Equipment device since February 2012. On June 26, 2014, the FDA announced the creation of a new product classification for Powered Exoskeleton devices. On October 21, 2014, the FDA published the summary for the new Powered Exoskeleton classification and designated it as being Class II, which requires the clearance of a 510(k) notice. On October 21, 2014, concurrent with the FDA’s publication of the reclassification of Powered Exoskeleton devices, the FDA issued the Company an “Untitled Letter” which informed the Company in writing of the agency’s belief that this new product classification applied to the Ekso GT device. On December 24, 2014, the Company filed a 510(k) notice for the Ekso robotic exoskeleton which was accepted by the FDA for substantive review on July 29, 2015. As discussed above, the Company received FDA clearance to market the Ekso GT in accordance with the device’s labeling on April 4, 2016. From September 2, 2015 to September 11, 2015, the Division of Bioresearch Monitoring Center for Devices and Radiological Health of the FDA conducted an inspection of the Company’s facility in Richmond, California. At the conclusion of the inspection, the FDA issued a Form FDA 483 with four observations. These observations were inspectional and did not represent a final FDA determination of non- compliance. The observations pertained to informed consent requirements, reporting of adverse results and records maintenance. On October 2, 2015, the Company responded to the FDA describing the corrective and preventive actions that the Company had implemented and continued to implement to address the FDA’s concerns. On March 30, 2016, the FDA accepted the Company’s corrective actions for the Form 483 observations that were generated during the FDA’s inspection. 17. Segment Disclosures The Company has three reportable segments, Medical Devices, Industrial Sales, and Engineering Services. The Medical Devices segment designs and engineers technology, and commercializes, manufactures, and sells exoskeletons for applications in the medical markets. The Industrial Sales segment designs, engineers, commercializes, and sells exoskeleton devices to allow able-bodied users to perform heavy duty work for extended periods. Engineering Services generates revenue principally from collaborative research and development service arrangements, technology license agreements, and government grants where the Company uses its robotics domain knowledge in bionic exoskeletons to bid on and procure contracts and grants from entities such as the National Science Foundation and the Defense Advanced Research Projects Agency. The Company evaluates performance and allocates resources based on segment gross profit margin. The reportable segments are each managed separately because they serve distinct markets, and one segment provides a service and the others manufacture and distribute unique products. The Company does not consider net assets as a segment measure and, accordingly, assets are not allocated.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL Not applicable. Item 9A. CONTROLS AND PROCEDURES Disclosure Controls and Procedures. Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of December 31, 2017. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective to ensure that information required to be disclosed in reports filed by us under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the required time periods and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. It should be noted that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment and makes assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. Management believes that the financial statements included in this report fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented. Management’s Report on Internal Control Over Financial Reporting The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in the U.S. Securities Exchange Act of 1934, Rules 13a-15(f) and 15d-15(f). The Company's internal control system was designed to provide reasonable assurance to the Company's management and board of directors regarding the preparation and fair presentation of published financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2017 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). The Company’s management believes that based on this criteria, as of December 31, 2017, the Company’s internal control over financial reporting is effective. The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by OUM LLP (“OUM”), an independent registered public accounting firm, as stated in their attestation report, which appears under Item 8 of this Annual Report on Form 10-K. OUM has issued an attestation report on the Company’s internal control over financial reporting, which report is included in OUM’s report on the Company’s consolidated financial statements, which appear under Item 8 of this Annual Report on Form 10-K. Changes in Internal Control Over Financial Reporting: Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016. Based on this assessment, our management concluded that our internal control over financial reporting was not effective as of December 31, 2016 because of a material weakness in the Company’s information technology (IT) general controls existed. While this material weakness did not result in any audit adjustments or misstatements, a reasonable possibility existed that a material misstatement in the Company’s annual or interim financial statements would not have been prevented or detected. Subsequent to December 31, 2016, we strengthened our internal controls by increasing our segregation of duties, implementing a more robust accounting and enterprise resource planning system (which became operational in October 2017), and putting in place several new monitoring controls. We believe that these measures have remediated the material weakness in our internal control over financial reporting related to IT general controls. 92 Table of Contents Other than as described above, there have been no other changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our fourth quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
