2018 ReportPeers and competitors of Digirad Corporation:
Avanos Medical(cid:3)2013(cid:3)ANNUAL(cid:3)REPORT Dear Fellow Shareholders, I am excited to be writing to you at the conclusion of a very transformational year at Digirad! To sum up our 2013 results and activities, I would choose to use a few key phrases: Change. Strategic Alignment. Profitability and Cash Flow. Shareholder Value. Excitement. Change. As many of you may know, Digirad has over the years experienced a number of healthcare market changes and challenges, both in reimbursement and in general market conditions, all of which have challenged the Company in finding the right strategic direction. Our past direction has resulted in financial losses in essentially every year since our initial public offering in 2004. Our business model was not sustainable and we needed to make a change, not only to ensure the longevity of our Company, but most importantly, to accomplish one of our major goals – to provide a return on our shareholders’ investment. Strategic Alignment. Based on our need for a change, we implemented a new strategic direction at Digirad in February 2013, which began with a substantial restructuring of your Company. Our new direction is intended to focus on what we believe is the most compelling portion of our business and the greatest potential for growth in the future: our Digirad Imaging Solutions (DIS) services business. We believe the model of providing relevant health care services to our customers on an “as needed, when needed and where needed basis” is the future of the healthcare industry. This has become more and more pronounced to us with the creation of the Affordable Care Act and other mandated changes around healthcare spending. The model of efficient, relevant and timely healthcare services will become more and more in demand as we move into the future as a result of these industry changes. We believe Digirad is well positioned to deploy this model and increase efficiency in the market. Based on this, we have increased our focus on growing our Digirad Imaging Solutions business, both from an organic growth perspective and via financially disciplined acquisitions. Both of these focus areas are proving achievable; we have had year-over-year organic revenue growth in our Digirad Imaging Solutions business and, in March 2014, we announced the strategic acquisition of Telerhythmics, an outsourced cardiac event monitoring business that is right in line with our service and efficiency focus. Of course, we believe the manufacturing and sales of our nuclear imaging cameras and related customer support of our Diagnostic Imaging division is a very viable business, both now and into the future with our large patent portfolio. However, we will move forward with a cost structure that is right-sized for the healthcare environment we are in today. Therefore, we have reduced costs around research and development, facilities and other fixed costs that were not relevant to our new strategic direction. We do believe that we can grow our Diagnostic Imaging business incrementally over time, and we have implemented a number of changes for long term organic growth, while at the same time ensuring that we are running a profitable business today. Profitability and Cash Flow. We essentially began implementing our restructuring plan on February 28, 2013. As time progressed over 2013, the proof of our restructuring plan success was becoming apparent. Our financial losses decreased in Q2 2013, and in Q3 2013, we recorded the most profitable quarter of our core businesses since our initial public offering in 2004. We followed that quarter with another very profitable quarter in Q4 2013. 1 We stated at the beginning of our restructuring plan that we could produce a profitable business that, on average, could generate $3 million to $4 million of free cash flow on an annual basis from our existing core businesses. Further, we have started returning some of that cash flow to you via a steady and sustainable quarterly dividend that began in November 2013. We still believe that our core business can deliver $3 million to $4 million of annual free cash flow, but we also believe, via careful planning and strategic focus, that we can build a robust service-oriented DIS business that can grow much larger than it is today. Shareholder Value. What does this all mean? It means shareholder value. For myself, and your executive management team, it is what we think of each day as we work for Digirad shareholders – what can we do to enhance value now and in the long term? We are very excited with our recent near term wins and proof of our restructuring plan success, but we are not done. Not even close. We believe our restructuring and the recent acquisition of Telerhythmics has set the stage for our future, but we have much more work to do. We are dedicated to continuing this work and growing Digirad from a very relevant service business of today to our ultimate goal – to be the first name that the healthcare market thinks of related to outsourced services. As needed, when needed, and where needed. Excitement. Finally, I hope I have conveyed our excitement! I can tell you on behalf of myself, and your entire executive management team, we are excited about our future prospects. Again, there is still a lot of work to do, but we are ready and will continue to work hard to deliver on our promises and on our goal of growing Digirad to be our market’s first thought for relevant and efficient health care services. In closing, I’d like to thank all our employees and you, our shareholders. We appreciate your continued support. Sincerely, Matthew G.

Corporate Information Digirad Corporation was incorporated in Delaware in 1997. Unless the context requires otherwise, in this report the terms “we,” “us” and “our” refer to Digirad® Corporation and our wholly-owned subsidiary, Digirad Imaging Solutions®, Inc. ITEM 1. BUSINESS Overview Digirad delivers convenient, effective, and efficient diagnostic imaging solutions on an as needed, when needed, and where needed basis. We are one of the largest national providers of in-office nuclear cardiology imaging and ultrasound services to physician practices, hospitals and imaging centers through our Digirad Imaging Solutions (“DIS”) business segment. We also sell medical diagnostic imaging systems including solid-state gamma cameras for nuclear cardiology and general nuclear medicine applications, as well as provide service on the products we sell through our Diagnostic Imaging segment. We were the first to commercialize solid-state nuclear gamma cameras for the detection of cardiovascular disease and other medical conditions. Our imaging systems are sold in both portable (i.e., movable) and fixed (i.e., stationary) configurations, and provide enhanced operability, improved patient comfort and can result in lower healthcare costs. Our triple-head Cardius® 3 XPO system provides significantly shorter image acquisition time when compared to traditional vacuum tube cameras. Our ergoTM imaging system is a large field-of-view general purpose imager featuring a sleek ergonomic (portable) design that offers clinical versatility and high performance. The ergoTM expands our reach beyond nuclear cardiology into general nuclear medicine with applicability to various disease states. Our nuclear cameras fit easily into floor spaces as small as seven feet by eight feet and facilitate the delivery of nuclear medicine procedures in a physician’s office or an outpatient hospital setting. The ergoTM can be used in the intensive and critical care units, pediatrics, trauma units, patient floors, emergency and operating rooms, women’s health or research areas. Through DIS, we offer a convenient and economically efficient imaging services program as an alternative to purchasing a gamma camera or ultrasound equipment or outsourcing the procedures to another physician or imaging center. For physicians who wish to perform nuclear imaging, echocardiography, vascular or general ultrasound tests, or any combination of these procedures in their offices, we provide the ability for them to engage our services, which includes the use of our imaging system, qualified personnel, and related items required to perform imaging in the their own offices and bill Medicare, Medicaid or one of the third- party healthcare insurers directly for those services. DIS services are also used by large and small hospitals, multi-practice physician groups, and imaging centers. The flexibility of our products and our DIS service allows physicians to ensure continuity of care and convenience for their patients and allows them to retain revenue from procedures they would otherwise refer to imaging centers and hospitals. DIS services are primarily provided to cardiologists, internal medicine physicians, and family practice doctors who enter into annual contracts for a set number of days ranging from once per month to five times per week. We experience some seasonality in our DIS business related to vacations, holidays, and inclement weather. Most of the DIS business focuses on cardiac care with an increase in the combination of cardiac, vascular and general ultrasound imaging in recent months. Many of the physicians who use DIS services are reliant on reimbursements from Medicare and third-party insurers where there has been downward pressure and uncertainty due to factors outside the physicians’ control. The uncertainty created by the 2010 healthcare reform laws, Congress’ continued deferred action on the Sustainable Growth Rate reimbursement factor (which is part of the Relative Value Unit calculation of reimbursements for all medical codes associated with the physician fee schedule) and other legislation has also impacted our business. These changes may require further modifications to our business model in order for our physician customers and us to maintain a viable economic model. 1 Our Diagnostic Imaging segment's revenue is derived primarily from selling solid-state gamma cameras and camera maintenance contracts. We sell our imaging systems to physician offices, hospitals and imaging centers primarily in the United States, although we have sold a small number of imaging systems internationally. We have relationships and agreements with distributors around the world and believe over time we will continue to develop these relationships to the point where we can eventually grow our sales outside the United States. On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly reduce costs and focus on maximizing cash flow from our DIS services business. This restructuring effort also included a reduction in force. The major portions of this restructuring plan were completed as of December 31, 2013. Going forward, we believe this restructuring plan will allow us to increase the overall profitability and operating cash flow of the Company. However, many other market, regulatory and competitive factors could impact the effectiveness of our restructuring plan. See Note 10 to the audited consolidated financial statements for further information. Market Opportunity Nuclear Imaging Nuclear imaging is a form of diagnostic imaging in which depictions of the internal anatomy or physiology are generated primarily through non-invasive means. Diagnostic imaging facilitates the early diagnosis of diseases and disorders, often minimizing the scope, cost and amount of care required and reducing the need for more invasive procedures. Currently, the major types of non-invasive diagnostic imaging technologies available are: x-ray, magnetic resonance imaging (MRI), computerized tomography (CT), ultrasound, positron emission tomography (PET, which is a form of nuclear imaging) and nuclear imaging. The most widely used imaging acquisition technology utilizing gamma cameras is single photon emission computed tomography, or SPECT. All of our current cardiac gamma cameras employ SPECT technology. Despite the increasing utilization rates of competing modalities such as CT, PET and MRI, and diagnostic procedures such as CT angiography, SPECT procedures performed with gamma cameras are expected to continue to be used for a substantial number of cardiac-specific imaging procedures according to industry experts. We believe continued utilization of SPECT technology will be driven by patients having easier access to nuclear medicine services at physicians’ offices, lower purchase and maintenance costs, a smaller physical footprint, and easier service logistics of gamma cameras. In an emerging trend in cardiology, SPECT technologies are being integrated with other imaging modalities, to form hybrid imaging modalities, such as SPECT/CT, resulting in improved clinical quality and diagnostic certainty. Clinical Applications for Nuclear Imaging Nuclear imaging is used primarily in cardiovascular, oncology, and neurological applications. Nuclear imaging involves the introduction of very low-level radiopharmaceuticals into the patient’s bloodstream. The radiopharmaceuticals are specially formulated to concentrate temporarily in the specific part of the body to be studied. The radiation signals emitted by the materials are then converted into an image of the body part or organ. Nuclear imaging has several advantages over other diagnostic imaging modalities, showing not only the anatomy or structure of an organ or body part, but also its function including blood flow, organ function, metabolic activity, and biochemical activity. Cardiologists and an increasing number of internists and other physicians either purchase our nuclear cameras or subscribe to our DIS services for in-office cardiac imaging for these advantages. Ultrasound Imaging Ultrasound is a form of diagnostic imaging in which depictions of the internal anatomy are generated primarily through non- invasive means. Ultrasound imagers use sonar techniques to generate diagnostic images that facilitate the early diagnosis of diseases and disorders, often minimizing the scope and cost of care required and reducing the need for invasive procedures. Clinical Applications for Ultrasound Imaging Ultrasound is one of the most widely used imaging techniques in the United States. Ultrasound imaging is used primarily in obstetrics, internal medicine, cardiovascular care, and vascular health applications. Ultrasound imaging involves the transmission and detection of sound waves into and from a patient’s body. The sound waves transmitted by the ultrasound system are then converted into an image of the body part or organ. Ultrasound imaging also shows the anatomy or structure of many internal organs or body parts, as well as key functional information—including blood flow, wall motion and organ function. Our ultrasound services are used by cardiologists, internists and other physicians for in-office echocardiography and general ultrasound imaging. Our Imaging Services DIS offers portable nuclear and ultrasound imaging services. We have obtained Intersocietal Commission for Nuclear Cardiology Laboratories (ICANL) and Intersocietal Commission for Echocardiography Laboratories (ICAEL) accreditation for our services. Our nuclear modality services include an imaging system, a certified nuclear medicine technologist and a cardiac stress technician 2 (often a certified or a trained nurse or paramedic), the supply of radiopharmaceuticals, and required licensing services for the performance of nuclear imaging procedures under the supervision of physicians. Our licensing infrastructure provides the radioactive materials license, radiation safety officer services, radiation safety training, monitoring and compliant policies and procedures, and the quality assurance function to ensure adherence to applicable state and federal nuclear regulations. The ultrasound imaging service is similar, in that we provide the ultrasound equipment and an experienced ultrasound technologist to perform the service. Our portable nuclear imaging operations use a “hub and spoke” model in which centrally located regional hubs anchor multiple van routes in the surrounding metropolitan areas. At our DIS hubs, clinical personnel load the equipment, radiopharmaceuticals, and other supplies onto specially equipped vans for transport to the physician’s office or other customer locations, where they set up the equipment for the day. After quality assurance testing, a technologist under the physician’s supervision will gather patient information, inject the patient with a radiopharmaceutical, and then acquire the images for interpretation by the physician. We provide nuclear and ultrasound services primarily under annual contracts for services delivered on a per-day basis. Under these agreements, physicians pay us a fixed amount for each day and they commit to the scheduling of a minimum number of service days during the contract term, which normally runs for one year. The same fixed payment amount is due for each day regardless of the number of patients seen or the reimbursement or payment obtained by the physician, practice, hospital, or imaging center. Our Products Digirad sells a line of nuclear imaging cameras for nuclear cardiology and general nuclear medicine applications. Our cameras are used in hospitals, imaging centers, physician offices and by mobile service providers. The central component of a nuclear camera is the detector and it ultimately determines the overall clinical quality of the image a camera produces. Our nuclear cameras feature detectors based on advanced proprietary solid-state technology developed by us. Solid-state systems have a number of benefits over conventional photomultiplier tube-based camera designs typically offered by our competitors. Our solid-state technology systems are typically 2 – 5 times lighter and considerably more compact than most traditional nuclear systems, making them far easier and less costly to build, very reliable, and able to be utilized for mobile applications. Our Cardius® family of dedicated cardiac SPECT solid-state imagers are noted for their compactness, portability and unique upright imaging capabilities that make it possible to image patients up to 500 pounds in a sitting position. Upright imaging makes it possible to image large bariatric, COPD (Chronic Obstructive Pulmonary Disease) or claustrophobic patients that typically could not be imaged lying down on competitive systems and afford our users the ability to generate added revenue to their practices. We offer fixed dual-head and triple-head cardiac camera models for dedicated use within a facility and a portable dual-head configuration that makes it possible to move the system to provide service to multiple rooms or sites. We are a market leader in the mobile solid-state nuclear camera segment. Our Cardius® XACT SPECT/CT system features a triple-head design and a low dose volume CT attenuation correction methodology, making it possible to perform studies faster with greater interpretation diagnostic confidence. Our XACT camera is sought by departments seeking to improve productivity, increase clinical accuracy or employ new low dose clinical protocols. Our ergoTM large-field-of-view imaging system is targeted to hospitals with multi-camera general nuclear medicine departments, academic centers, pediatric hospitals, regional trauma centers, women’s health centers, and cancer centers. Most general nuclear medicine departments have the need for a single-head planar portable camera for imaging patients more conveniently on hospital stretchers, for imaging patients that can not be moved, and for imaging patient’s at their bedside (pediatrics, intensive care units, critical care units, emergency rooms, surgical suites, women’s health clinics, or on regular patient floors). A single-head planar camera provides a more economical and convenient way to perform approximately 25% or more of all studies commonly performed in general nuclear medicine. It also opens the door to perform studies on critically ill patients in the patient’s room and the ability to perform molecular breast imaging protocols that offer new revenue generation potential while improving the standard of patient care. Competitive Strengths We believe that our competitive strength is based on our proprietary solid-state technology in general nuclear medicine and cardiology as well as our streamlined approach to providing diagnostic imaging services to our customers at the point of need. • Broad Portfolio of Cardiovascular Imaging Services. One of our main competitive advantages is our ability to offer nuclear cardiology, echocardiography and complete vascular imaging services. Our ability to offer multiple services strengthens our competitive position. The depth of services offered varies depending on the local market opportunity, availability of personnel and credentialing requirements in the individual markets. • Unique Dual Sales and Service Offering. We sell imaging systems to physicians who wish to perform nuclear imaging in their facilities and manage the related service logistics. Through DIS, we offer both nuclear and ultrasound services 3 in which we provide our systems and certified personnel to physicians on an annual basis in flexible increments, ranging from one day per month to several days per week without requiring them to make a capital investment, hire personnel, obtain licensure, or manage other logistics associated with operating a nuclear imaging site. Our ability to service our customers in a variety of capacities from selling the capital equipment directly at the point of need or being more flexible in a service-oriented models allows us to serve our customers exactly according to their needs. • Leading Solid-State Technology. Our solid-state gamma cameras utilize proprietary photo-detector modules which enable us to build smaller and lighter cameras that are portable, with a degree of ruggedness that can withstand the vibration associated with transportation. We offer a more geometric-efficient design for cardiology and with our our ergoTM imaging system, the first large field-of-view solid-state detector system for use in general nuclear medicine, pediatrics, women’s health and surgery. • Portable Applications through Reduced Size and Weight. Our cameras, depending on the model, weigh anywhere from 600 to 1,000 pounds. Competitive anger photomultiplier tube-based technology cameras generally weigh 2 to 5 times as much. Our dedicated cardiac imagers require a floor space of as little as seven feet by eight feet and generally can be installed without facility renovations and use standard power. Our portable cameras are ideal for mobile operators or practices desiring to service multiple office locations or imaging facilities, and for use in our DIS in-office service business. We bring nuclear technology to the patient. • • • Speed and Image Quality. We believe our Cardius® 3 XPO and X-ACT rapid imaging dedicated cardiac cameras, equipped with our proprietary nSPEED 3DOSEM software, can acquire images up to four times faster than conventional fixed 90 or variable dual-head photomultiplier vacuum tube camera designs with equivalent image quality. Increased imaging speed optimizes workflow and resource utilization and allows for reduction of the administered dose of radiation to patients or the use of low dose imaging protocols, which we believe is increasingly of interest to our physician customers. Improved Patient Comfort and Utilization. We believe the upright and open architecture of our patient chair reduces patient claustrophobia and increases patient comfort when compared to traditional vacuum tube-based imaging systems, the majority of which require the patient to lie flat and have detector heads rotate around the patient. Upright imaging positioning also reduces false indications that can result from organs pushing-up against the heart while patients are on their backs. Our Cardius® XPO camera series allows for the imaging of patients weighing up to 500 pounds. Intellectual Property Portfolio. We have developed an intellectual property portfolio that includes product, component and process patents covering various aspects of our imaging systems. We have 38 issued U.S. patents. We also license patents from third parties to enhance our product offering. In addition to our patent portfolio, we have developed proprietary manufacturing, business know-how, and trade secrets. This portfolio of intellectual property provides us with a distinct competitive advantage. Business Strategy Our goals are to achieve and maintain consistent profitability and operating cash flow generation, and then grow our business over time via the following: • DIS. As a result of our Diagnostic Imaging restructuring announced in February 2013, we have refocused our efforts to drive profitability and cash flow generation in our DIS services business, with efforts to help it grow over time. We believe 2013 has showed signs of stabilization in relation to healthcare reform and reimbursement uncertainties and we believe the market will be more stable going forward. To further our strategy, we believe that we have the opportunity to have a focused sales approach within our current operating jurisdictions to drive density of operations, which will allow us to take advantage of economies of scale and achieve better utilization of our capital equipment and personnel. Further, we believe there are a variety of smaller mobile imaging businesses within the United States, both inside and outside our current operating jurisdictions that we may be able to acquire and further increase our growth rate and density of operations. As we have done in the past, we expect to continue supporting our physician customers by working with them to adjust our DIS business model for changes in the market as well as continuing to focus on aligning our labor and other costs with the variable nature of our revenue streams. Going forward, we continue to see value in our service channel via strategic and technological initiatives designed to increase revenue per day for us and our physician customers, as well as expand our service model offerings. • Diagnostic Imaging. In order to overcome the past market decline of cardiac specific cameras, we intend to focus efforts on markets beyond the cardiac-specific nuclear market. Our Cardius® XACT camera is particularly geared toward hospitals and large physician practices. Our ergoTM imaging system also addresses the larger market of general nuclear imaging and provides us with a new untapped market opportunity within the hospital. Our ergoTM imaging system is not just part of a hospital nuclear suite, it is a camera that enables the imaging to be performed wherever the patient is located and has great promise in areas of the hospital where previously no nuclear imaging has been performed, such as the emergency 4 room and the surgical suite. Further, as a result of our Diagnostic Imaging restructuring announced in February 2013, we believe we can improve the overall profitability and cash flow from our Diagnostic Imaging business, primarily from reduced but focused research and development efforts, reduced overhead and manufacturing costs, as well as outsourcing the majority of our manufacturing operations. Further, we have developed relationships with distributors outside the United States that we believe may, over time, enhance our ability to increase sales of our nuclear imaging cameras outside the United States. See Note 10 to the audited consolidated financial statements for further information regarding our Diagnostic Imaging restructuring announcement. Business Segments Our business is organized into two reportable segments: Digirad Imaging Solutions (DIS) and Diagnostic Imaging. See Note 14 to the audited consolidated financial statements for certain segment financial data relating to our business. Manufacturing We manufacture our advanced, solid-state nuclear imaging cameras by employing a strategy that combines our internal design expertise and proprietary process technology with highly-qualified outsourced manufacturing providers. Prior to 2013, we manufactured the majority of the component parts associated with our cameras, along with selective outsourcing. In September 2013, we announced an agreement to move much of this process to a qualified, third party manufacturer. We are currently engaged in a process to transition this manufacturing to the third party, and anticipate that substantially all of the transition will be completed by June 2014. We believe that increasing our outsourcing efforts will result in increased efficiencies, flexibility to meet customer demand, and over time, cost reductions. We will continue to perform some final assembly services and final system performance tests at our facility. All of our outsourced suppliers of critical materials, components, and subassemblies undergo ongoing quality audits by us. We and our third-party manufacturers are subject to FDA Quality System Regulations, state regulations, such as those promulgated by the California Department of Health Services, and standards set by the International Organization for Standardization, or ISO. We are currently certified to the EN ISO 13485:2012 quality standard. We have certification authorizing CE Marking of our Cardius® XPO, Cardius® X-ACT, ergoTM and 2020tc family of gamma cameras, as well as U.S. Food and Drug Administration (FDA) 510(k) clearance for our complete nuclear imaging camera product line. The CE Mark is a requirement for selling in many international markets. In addition, the X-ACT camera utilizes a x-ray technology to provide attenuation correction information for the SPECT reconstruction. We also have received FDA Indications for Use for our ergoTM LFOV General Purpose Imager for lymphatic scintigraphy, parathyroid scintigraphy and molecular breast imaging. Raw Materials We use a wide variety of materials, metals and mechanical and electrical components for production of our products. In addition, our operations involve the use of radiopharmaceuticals. We primarily purchase these materials from external suppliers, some of which are single-source suppliers. We purchase materials from selected suppliers based on quality assurance, cost effectiveness and constraints resulting from regulatory requirements, and we work closely with our suppliers to assure continuity of supply while maintaining high quality and reliability. Global commodity supply and demand can ultimately affect pricing of certain of these raw materials. Though we believe we have adequate available sources of raw materials, there can be no guarantee that we will be able to access the quantity of raw material needed to sustain operations as well as at a cost effective price. Competition The market for nuclear and ultrasound imaging services and systems is highly competitive. Our business in the private practice and hospital sectors continues to face the challenges of demand for nuclear imaging equipment and services, which we believe reflects in part, the impact of the Deficit Reduction Act on the reimbursement environment and the 2010 Healthcare Reform laws, competition from competing imaging modalities, such as CT angiography, PET, and hybrid technologies, as well as general uncertainty in overall healthcare and changes in healthcare, such as the Affordable Care Act. These concepts, along with, until recently, an overall depressed economy, has impacted our operations. We believe that the principal competitive factors in our market include acceptance by physicians, including relationships that we develop with our customers, budget availability for our capital equipment, qualification for reimbursement, pricing, ease-of-use, reliability and mobility. In providing DIS imaging services, we compete against many smaller local and regional nuclear and/or ultrasound providers, often owner-operators that may or may not follow all relevant health care law and procedures, reducing their overall operating costs. The fixed-installation operators often utilize older, used equipment and the mobile operators may use older Digirad single- head cameras or newer dual-head cameras. We are the only mobile provider with our own exclusive source of triple-head mobile systems. Some competing operators place new or used cameras into physician offices and then provide the staffing, supplies and other support as an alternative to a DIS service contract. In addition, we compete against imaging centers that install fixed nuclear 5 gamma cameras and make them available to referring physicians in their geographic vicinity. In these cases, the physician sends their patients to the imaging center. In selling our imaging systems, we compete against several large medical device manufacturers who offer a full line of imaging cameras for each diagnostic imaging technology, including x-ray, MRI, CT, ultrasound, nuclear medicine, or SPECT/CT and PET/ CT hybrid imagers. The existing nuclear imaging systems sold by these competitors have been in use for a longer period of time than our products and are more widely recognized and used by physicians and hospitals for nuclear imaging; however, they are generally not solid-state, light-weight, as flexible or portable. Additionally, certain medical device companies have developed a version of solid-state gamma cameras which may directly compete with our product offerings. Many of the larger multi-modality competitors enjoy significant competitive advantages over us, including greater brand recognition, greater financial and technical resources, established relationships with healthcare professionals, broader distribution networks, more resources for product development and marketing and sales and the ability to bundle products to offer discounts. Sales We maintain two sales organizations, which operate independently but in cooperation with each other: Diagnostic Imaging sales and DIS sales. The sales teams work together to ensure that our customers make the right decisions in either utilizing our mobile imaging services or purchasing a nuclear imaging camera for which ever situation best suits their needs, volume, and overall impact to their business. DIS sales teams are aligned across geographic areas we have established in order to better serve local market needs. Our DIS business is segregated into twelve areas, each area is led by a local or regional business director who is responsible for the needs of our customers in that area and who has local operational responsibility. We expect to increase DIS market penetration by focusing on those hospitals and practices that are already within an existing DIS operational area in order to increase the density of our current operations and increase the efficiency of our overall cost structure. We also plan, over time, to utilize the customers and relationships that we have to offer other emerging services that have clinical need and can be provided while at that customer site. The Diagnostic Imaging business sells imaging systems directly to physicians, primary care multi-specialty groups, clinics and hospital customers in the United States. Diagnostic Imaging also has distribution agreements with third parties throughout the world and believes over time these relationships can be developed to increase presence and sales to counties outside the United States. Research and Development In the past, we have committed a significant amount of resources to research and development activities, primarily surrounding developing new nuclear imaging cameras and alternative applications of that technology. In February 2013, we made a decision to change our strategic direction and focus efforts on expanding our DIS mobile diagnostic imaging services business, as well as limiting our nuclear imaging system sales through Diagnostic Imaging to those cameras that already have a proven track record of quality, reliability and customer need. Based on the new strategic direction, we will be focusing significantly less effort on developing new diagnostic imaging systems. We believe our current systems, with their state of the art technology and robust underlying patents, will be very relevant systems for many years into the future. We will continue to enhance and adjust our existing systems for the changing nuclear imaging market, including software updates and smaller enhancements. However, to accomplish any changes and enhancements, we will utilize what we believe is a deep available pool of contract engineers on a flexible, as needed basis. We have eliminated the fixed costs of a fully staffed research and development department. As a result, we expect our research and development costs to be minimal going into the future. As mentioned previously, prior to early 2013, our research and development efforts have been primarily focused on developing our next generation products and alternative applications of our technology. Our research and development expense was $1.0 million, $3.7 million, and $2.7 million in 2013, 2012, and 2011, respectively. Government Regulation We and our medical professional customers must comply with an array of federal and state laws and regulations. Violations of such laws and regulations can be punishable by criminal, civil, and/or administrative sanctions, including, in some instances, exclusion from participation in healthcare programs such as Medicare and Medicaid. Accordingly, we maintain a vigorous compliance program and a hotline that permits our personnel to report violations while remaining anonymous if they wish. The following is a summary of some of the laws and regulations applicable to our business: • Anti-Kickback Laws. The Medicare/Medicaid Patient Protection Act of 1987, as amended, which is commonly referred to as the Anti-Kickback Statute, prohibits us from knowingly and willingly offering, paying, soliciting, or receiving any form of remuneration in return for the referral of items or services, or to purchase, lease, order or arrange for or recommend purchasing, leasing, or ordering any good, facility service or item, for which payment may be made under a federal 6 healthcare program. Violation of the federal anti-kickback law is a felony, punishable by criminal fines and imprisonment, or both, and can result in civil penalties and exclusion from participation in healthcare programs such as Medicare and Medicaid. Many states have adopted similar statutes prohibiting payments intended to induce referrals of products or services paid by Medicaid or other nongovernmental third-party payors. • Physician Self-Referral Laws. Federal regulations commonly referred to as the “Stark Law” prohibit physician referrals of Medicare or Medicaid patients to an entity for certain designated health services if the physician or an immediate family member has an indirect or direct financial relationship with the entity, unless a statutory exception applies. We believe that referrals made by our physician customers are eligible to qualify for the “in-office ancillary services” exception to the Stark Law, provided that the services are provided or supervised by the physician or a member of his or her “Group Practice,” as that term is defined under the law, the services are performed in the same building in which the physicians regularly practice medicine, and the services are billed by or for the supervising physician or Group Practice. Violations of the Stark Law may lead to the imposition of penalties and fines, the exclusion from participation in federal healthcare programs, and liability under the federal False Claims Act and its whistleblower provisions. Many states have adopted similar statutes prohibiting self-referral arrangements that cover all patients and not just Medicare and Medicaid patients. • HIPAA. The Health Insurance Portability and Accountability Act of 1996, or HIPAA, prohibits schemes to defraud healthcare benefit programs and fraudulent conduct in connection with the delivery of, or payment for, healthcare benefits, items or services. HIPAA also establishes standards governing electronic healthcare transactions and protecting the security and privacy of individually identifiable health information. Some states have also enacted privacy and security statutes or regulations that, in some cases, are more stringent than those issued under HIPAA. The American Recovery and Reinvestment Act of 2009, enacted February 17, 2009 made significant changes to HIPAA privacy and security regulation. Effective February 17, 2010, we are regulated directly under all of the HIPAA rules protecting the security of electronic individually identifiable health information and many of the rules governing the privacy of such information. • Medical Device Regulation. The FDA classifies medical devices, such as our cameras, into one of three classes, depending on the degree of risk associated with the device and the extent of control needed to ensure safety and effectiveness. Devices deemed to pose lower risk are placed in either class I or II, which generally requires the manufacturer to submit to the FDA a pre-market notification requesting permission for commercial distribution. This process is known as 510 (k) clearance. Devices deemed to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices, are placed in Class III, requiring an approved Premarket Approval Application (PMA). Our cameras are Class II medical devices which have been cleared for marketing by the FDA. We are also subject to post-market regulatory requirements relating to our manufacturing process, marketing and sales activities, product performance and medical device reports should there be deaths and serious injuries associated with our products. • Pharmaceutical Regulation. Federal and state agencies, including the FDA and state pharmacy boards, regulate the radiopharmaceuticals used in our DIS business. • Radioactive Materials Laws. We must maintain licensure under, and comply with, federal and state radioactive materials laws, or RAM laws. RAM laws require, among other things, that radioactive materials are used by, or that their use be supervised by, individuals with specified training, expertise, and credentials and include specific provisions applicable to the medical use of radioactive materials. Intellectual Property We rely on a combination of patent, trademark, copyright, trade secret, and other intellectual property laws, nondisclosure agreements, and other measures to protect our intellectual property. We require our employees, consultants, and advisors to execute confidentiality agreements and to agree to disclose and assign to us all inventions conceived during the work day, using our property, or which relate to our business. Despite any measures taken to protect our intellectual property, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. Patents We have developed a patent portfolio that covers our overall products, components and processes. We have 38 issued U.S. patents. The patents cover, among other things, aspects of solid-state radiation detectors including our photodiodes, signal processing, and system configuration. Our issued patents expire between August 9, 2016 and April 20, 2030. We have multiple patents covering unique aspects and improvements for many of our products. We have entered into royalty-bearing licenses for several U.S. patents with third parties, where we are the licensee, for exclusive or non-exclusive use in nuclear imaging (subject to certain reservation of rights by the U.S. Government). In addition to our solid-state detector and photodiode technology patents, we hold specific patents for an alternative solid-state method using Cadmium Zinc Telluride that we previously pursued for use 7 in gamma cameras. While each of our patents applies to nuclear medicine, many also apply to the construction of area detectors for other types of medical and non-medical imagers and imaging methods. Trademarks As of December 31, 2013, we hold trademark registrations in the United States for the following marks: 2020tc IMAGER®, Digirad®, DigiServ®, Cardius®, SPECTour®, SPECTpak Plus®, Solidium®, and DigiTech® . We have obtained and sought trademark protection for some of these listed marks in the European Union and Japan. Reimbursement Our customers typically rely primarily on the Medicare and Medicaid programs and private payors for reimbursement. As a result, demand for our products is dependent in part on the coverage and reimbursement policies of these payors. Third party coverage and reimbursement is subject to extensive federal, state, local, and foreign regulation, and private payor rules and policies. In many instances, the applicable regulations, policies and rules have not been definitively interpreted by the regulatory authorities or the courts, and are open to a variety of interpretations and are subject to change without notice. The scopes of coverage and payment policies vary among third-party private payors. For example, some payors will not reimburse a provider unless the provider has a contract with the payor, and in many instances such payors will not enter into such contracts without the approval of a third party “radiology benefit manager” (or RBM) that the payor compensates based on reducing the payor’s imaging expense. Other payors prohibit reimbursement unless physicians own or lease our cameras on a full-time basis, or meet certain accreditation or privileging standards. Such payor requirements and limitations can significantly restrict the types of business models we can successfully utilize. Medicare reimbursement rules are subject to annual changes that may affect payment for services that our customers provide. In addition, Congress has passed healthcare reform proposals that are intended to expand the availability of healthcare coverage and reduce the growth in healthcare spending in the U.S. Many of these laws impact the services that our customers provide. For instance, the law has established an independent body that will have the power to recommend and mandate reimbursement levels for various healthcare services, including the imaging services we provide. An eventual outcome of these healthcare reform laws is expected to be changes, currently unspecified, in reimbursements and we will have to adapt to these changes. We are unable at this time to predict the full impact of health care reform on the diagnostic radiology services that our customers provide. Medicare reimbursement rules impose many standards and policies on the payment of services that our customers provide. For instance, starting in 2012, physicians billing for the technical component of nuclear imaging tests must be accredited by a government-approved independent accreditation body and many private payors are adopting similar requirements. We have made available to our customers a service to assist them in obtaining and maintaining the required accreditation. We believe we have structured our contracts in a manner that allows our customers to seek reimbursement from third-party payors in compliance with the law. Our physician customers typically bill for both the technical and professional components of the tests. Assuming they meet certain requirements including, but not limited to, performing and documenting bona fide interpretations and providing the requisite supervision of the non-physician personnel performing the tests, they may bill and be paid by Medicare. If the failure to comply is deemed to be “knowing” or “willful,” the government could seek to impose fines or penalties, and we may be required to restructure our agreements and/or respond to any resultant claims by such customers or the government. Our hospital customers typically seek reimbursement by Medicare for outpatient services under the Medicare Hospital Outpatient Prospective Payment System. Employees As of December 31, 2013, we had a total of 253 full time employees, of which 174 were employed in clinical related positions, 35 in operational roles, 28 in general and administrative functions, and 16 in marketing and sales. We also utilize varying amounts of temporary workers as as necessary to fulfill customer requirements. We have not experienced any work stoppages and consider our employee relations to be good. Availability of Public Reports We file electronically with the Securities and Exchange Commission, or SEC, our annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934.

ITEM 1A. RISK FACTORS Risks Related to Our Business and Industry We may not be able to achieve the benefits of our restructuring efforts. On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly reduce costs and focus on maximizing cash flow from our DIS service business. Restructuring efforts include many complexities, which include but are not limited to changing the way a business conducts operations, changing of key personnel, changing the process in how we manufacture and sell our products, modifying contracts, severing employees and working with less resources. There is no guarantee that our restructuring efforts will increase profitability and cash flow in our Diagnostic Imaging business, and our efforts could cause unforeseen complexities and additional cash outflows. Our revenues may decline further due to reductions in Medicare reimbursement rates. The success of our business is largely dependent upon our medical professional customers' ability to provide diagnostic imaging care to their patients in an economically sustainable manner, either through the purchase of our imaging systems or using our services, or both. Our customers are directly impacted by changes (decreases and increases) in governmental and private payor reimbursements for diagnostic imaging. Although we are not directly impacted by changes in reimbursements, we make every effort to act as business partners with our physician customers. For example, in 2010, we proactively adjusted our imaging services rate down due to the dramatic reimbursement declines that our customers faced from the Centers for Medicare & Medicaid Services. Reimbursements remain a source of concern for our customers and downward pressure on reimbursements causes greater pricing pressure on our services and influences the buying decisions of our individual physician Diagnostic Imaging product customers. Although the gap is closing, hospital reimbursements remain higher than in-office reimbursements. Our Diagnostic Imaging segment's products are targeted to serve the hospital market. Only a small portion of our DIS business segment operates in the hospital market. Further reductions in reimbursements could significantly impact the viability of in-office imaging performed by independent physicians. The uncertainty surrounding this issue and the historical decline in reimbursements has resulted in cancellations of imaging days in our imaging services business and the delay of purchase and service decisions by our existing and prospective customers in our Diagnostic Imaging business segment. Additional declines in Medicare/Medicaid reimbursement for our relevant diagnostic imaging modalities are possible due to many factors, including but not limited to the threatened implementation of the federal sustainable growth factor (SGR). The SGR is part of the relative value unit (RVU), a formula that was enacted by Congress as part of the Balanced Budget Act of 1997 to control the cost of the Medicare program. It applies to all health services paid for by Medicare, not just diagnostic imaging. The application of the SGR has been delayed by Congress for many years, with annual delays of implementation each year. Most recently on December 26, 2013, the Bipartisan Budget Act of 2013 was signed into law which included the Pathway to SGR Reform Act of 2013 (the "Act"). Most notably, the Act provides a short-term reprieve from the Medicare physician fee schedule cut while lawmakers work to finalize a longer-term solution. It also extends Medicare provider payment cuts under existing sequestration authority for two years and makes a variety of other policy changes, including the Short-Term Medicare Physician Fee Schedule Patch. The final Medicare physician fee schedule rule, which was published on December 10, 2013, called for a 20.1% reduction in the fee schedule update for 2014, largely as a result of the SGR formula. The Act blocks the 20.1% cut and replaces it with a 0.5% increase for services provided through March 31, 2014. This temporary payment increase is intended to provide Congress with additional time to finalize pending legislation that would permanently repeal the SGR policy and replace it with a period of stable reimbursement rates followed by reimbursement linked to quality of care. There is no assurance that concepts surrounding SGR will be timely or favorably resolved, and if not favorably resolved, it could have a material adverse impact on our business. Our revenues may decline further due to changes in diagnostic imaging regulations and the use of third party benefit managers by states and private payors to drive down imaging volumes. Nuclear medicine is a “designated health service” under the federal physician self-referral prohibition law known as the “Stark Law,” which states that a physician may not refer designated health services to an entity with which the physician or an immediate family member has a financial relationship, unless a statutory exception applies. Our business model and service agreements are structured to enable our physician customers to meet the statutory in-office ancillary services (IOAS) exception to the Stark Law allowing them to perform nuclear diagnostic imaging services on their patients in the convenience of their own office. From time- to-time, the Centers for Medicare and Medicaid Services and Congress have proposed to modify the IOAS to further limit or eliminate this exception. Various lobbying organizations are pushing for, and the Medicare Payment Advisory Commission 9 (MedPAC) is actively discussing recommending that Congress limit the availability of the IOAS exception in order to reduce federal healthcare costs. Legislation has been introduced in prior Congresses to modify or eliminate the exception, but has not been enacted. The outcome of these efforts is uncertain at this time; however, the limitation or elimination of the IOAS exception could significantly impact our DIS business segment as currently structured. Our customers who perform imaging services in their office also experience the continuing efforts by some private insurance companies to reduce healthcare expenditures by hiring radiology benefit managers to help them manage and limit imaging. The federal government has also set aside monies in the 2009 recession recovery acts to hire radiology benefit managers to provide image management services to Medicare/Medicaid and MedPAC has recommended and the Centers for Medicare & Medicaid Services has, in the past, proposed legislation requiring Medicare physicians who engage in a relatively high volume of medical imaging be required to obtain pre-authorization through a radiology benefit manager. A radiology benefit manager is an unregulated entity that performs various functions for private payors and managed care organizations. Radiology benefit manager activities can include pre-authorization for imaging procedures, setting and enforcing standards approving which contracted physicians can perform the services, such as requiring even the most experienced and highly qualified cardiologists to obtain additional board certifications or interfering with the financial decision of the private practitioner by requiring them to own their own imaging system and not allowing them to lease the system. The radiology benefit managers often do not provide written documentation of their decisions or an appeals process, leaving leasing physicians unable to challenge their decisions with the carrier or the state insurance department. Unregulated radiology benefit manager activities have and could continue to adversely affect our physician customers' ability to receive reimbursement, therefore impacting our customers' decision to utilize our DIS imaging services. We intend to outsource the manufacturing of the majority of the components associated with our nuclear gamma cameras to streamline operations and reduce costs. Outsourcing our manufacturing process may be difficult, could result in business disruptions caused by the outsource partner and may not result in significant cost savings. In September 2013, we announced an agreement to outsource the majority of our nuclear gamma camera production processes to a third party. The manufacturing of these cameras will be transitioned to the third party manufacturer over several months before it is fully implemented. This transition process may prove to be difficult, reducing the savings and benefit of the overall outsourcing agreement. Following the completion of the outsourcing effort, we will be reliant on our third party manufacturer, which would expose us to any disruptions in their supply chain, processes, employees, and other underlying activities associated with their manufacturing process. Should we experience a disruption in their supplying of cameras, we may not be able to find a suitable alternative solution in a reasonable period of time which may cause a disruption in camera sales. Manufacturing of our nuclear imaging cameras is highly dependent upon the availability of certain suppliers, thereby making us vulnerable to supply problems that could harm our business. Our manufacturing process relies on a limited number of third parties to manufacture and supply certain key components of our products. Alternative sources of production and supply may not be readily available or may take several months to scale-up and develop effective production processes. If a disruption in the availability of parts or in the operations of our suppliers were to occur, such as with respect to components manufactured in Japan, our ability to build gamma cameras could be materially adversely affected. We have developed backup plans and have alternative procedures that are designed to prevent delays in production should be experience a disruption. However, if these plans are unsuccessful, delays in the production of our gamma cameras for an extended period of time could cause a loss of revenue and/or higher production costs, which could significantly harm our business and results of operations. Our diagnostic imaging service operations are highly dependent upon the availability of certain radiopharmaceuticals, thereby making us vulnerable to supply problems and price fluctuations that could harm our business. Our diagnostic imaging service business involves the use of radiopharmaceuticals. There were significant disruptions in the international supply of these radiopharmaceuticals in 2010, which caused us to cancel services that would have otherwise been provided and this adversely affected our customers, as well as our financial condition in 2010. Since this event, we generally have had sufficient supply, but do experience short-term shortages from time to time. There are two major nuclear reactors supplying medical radiopharmaceuticals worldwide; however, there is no guarantee that the reactors will remain in good repair and our supplier will have continuing access to ample supply of our radiopharmaceutical product. If we are unable to obtain an adequate supply of the necessary radiopharmaceuticals, we may be unable to utilize our personnel and equipment through our in-office service operations, or the volume of our services could decline and our business may be adversely affected. Shortages can also cause price increases that may not be accounted for in third party reimbursement rates, thereby causing us to lose margin or require us to pass increases on to our physician customers. 10 Our business is not widely diversified. We provide our diagnostic imaging services and sell our products primarily into the cardiac nuclear and ultrasound imaging private practice and in-office markets. We may not be able to leverage our assets and technology to diversify our products and services in order to generate revenue beyond the cardiac nuclear and ultrasound imaging private practice markets. If we are unable to diversify our product and service offerings, our financial condition may suffer. We compete against businesses that have greater resources and different competitive strengths. The market for cardiac nuclear imaging cameras is limited and has experienced some declines. Some of our competitors have greater resources and a more diverse product offering than we do. Some of our competitors also enjoy significant advantages over us, including greater brand recognition, greater financial and technical resources, established relationships with healthcare professionals, larger distribution networks, and greater resources for product development, as well as more extensive marketing and sales resources. Additionally, certain companies have developed portable cameras that directly compete with our product offerings. If we are unable to expand our current market share, our revenues and related financial condition could decline. In addition, our imaging services customers may switch to other service providers. Our DIS imaging services segment competes against small local, owner operated or regional businesses, some of whom have the advantage of a lower cost structure, and against imaging centers that install nuclear gamma cameras and make them available to physicians in their geographic vicinity. If these competitors are able to win significant portions of our business, our sales could decline significantly. Our financial condition could be adversely affected under such circumstances. Our quarterly and annual financial results are difficult to predict and are likely to fluctuate from period to period. We have historically experienced seasonality in our DIS business, and in the past, volatility due to the changing health care environment, the variable supply of radiopharmaceuticals, and the downturn in the U.S. economy. While our physicians are obligated to pay us for imaging days to which they have committed, our contracts permit some flexibility in scheduling when services are to be performed. We cannot predict with certainty the degree to which seasonal circumstances such as the summer slowdown, winter holiday vacations and weather conditions may affect the results of our operations. We have also experienced fluctuations in demand of our cardiac nuclear gamma cameras due to economic conditions, capital budget availability and other financial or business reasons. In addition, due to the way that customers in our target markets acquire our products, a large percentage of our camera orders are booked during the last month of each quarterly accounting period. As such, a delivery delay of only a few days may significantly impact quarter-to-quarter comparisons of our results of operations. Moreover, the sales cycle in our Diagnostic Imaging segment for cameras is typically lengthy, particularly in the hospital market, which may cause us to experience significant revenue fluctuations. Our common stock has a low trading volume and our option plan could affect the trading price of our common stock. Our common stock historically has had a low trading volume. Any significant sales of our common stock may cause volatility in our stock price. We also have registered shares of common stock that we may issue under our employee benefit plans or from our treasury stock. Accordingly, these shares can be freely sold in the public market upon issuance, subject to restrictions under the securities laws. If any of these stockholders, or other selling stockholders, cause a large number of securities to be sold in the public market without a corresponding demand, the sales could reduce the trading price of our common stock. One or more stockholders holding a significant amount of our common stock might be able to significantly influence matters requiring approval by our stockholders, possibly including the election of directors and the approval of mergers or other business combination transactions. We spend considerable time and money complying with federal and state laws, regulations and other rules, and if we are unable to comply with such laws, regulations and other rules, we could face substantial penalties. We are directly, or indirectly through our physician customers, subject to extensive regulation by both the federal government and the states in which we conduct our business, including: the federal Medicare and Medicaid anti-kickback laws and other Medicare laws, regulations, rules, manual provisions, and policies that prescribe requirements for coverage and payment for services performed by us and our physician customers; the federal False Claims statutes; the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended in 2009 under the HITECH Act that places direct legal obligations and higher liability on us with respect to the security and handling of personal health information; the Stark Law; the federal Food, Drug and Cosmetic Act; federal and state radioactive materials laws; state food and drug and pharmacy laws and regulations; state laws that prohibit the practice of medicine by non-physicians and fee-splitting arrangements between physicians and non- physicians; state scope-of-practice laws; and federal rules prohibiting the mark-up of diagnostic tests to Medicare under certain circumstances. If our physician customers are unable or unwilling to comply with these statutes, regulations, rules, and policies, rates of our services and products could decline and our business could be harmed. Additionally, new government mandates will require us to provide a certain baseline of health benefits and premium contribution for our employees and their families or pay 11 governmental penalties. Some of these costs are not tax deductible. We have opted to provide this coverage to our employee base in order to maintain retention of qualified medical technicians and other professionals rather than plan to pay penalties to the government. Either option will result in additional costs to us and could negatively impact our cash reserves. We maintain a compliance program to identify and correct any compliance issues and remain in compliance with all applicable laws, to train employees, to audit and monitor our operations, and to achieve other compliance goals. Like most companies with compliance programs, we occasionally discover compliance concerns. In such cases, we take responsive action including corrective measures when necessary. There can be no assurance that our responsive actions will insulate us from liability associated with any detected compliance concerns. If our past or present operations are found to be in violation of any of the laws, regulations, rules, or policies described above or the other laws or regulations to which we or our customers are subject, we may be subject to civil and criminal penalties, damages, fines, exclusion from federal or state health care programs, or the curtailment or restructuring of our operations. Similarly, if our physician customers are found to be non-compliant with applicable laws, they may be subject to sanctions which could have a negative impact on us. Any penalties, damages, fines, curtailment or restructuring of our operations could adversely affect our ability to operate our business and our financial results. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management's attention from the operation of our business, and damage our reputation. Health care policy changes may have a material adverse effect on us. In response to perceived increases in health care costs in recent years, there have been and continue to be proposals by the federal government, state governments, regulators, and third-party payers to control these costs and, more generally, to reform the U.S. health care system. Certain of these proposals could limit the prices we are able to charge for our products or the amounts of reimbursement available for our products and could limit the acceptance and availability of our products. The adoption of some or all of these proposals could have a material adverse effect on our financial position and results of operations. In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act and the Health Care and Education Affordability Reconciliation Act of 2010. The legislation imposes significant new taxes on medical device makers in the form of a 2.3% excise tax on all U.S. medical device sales beginning in 2013. Under the legislation, the total cost to the medical device industry is expected to be approximately $20 billion over ten years. This significant increase in the tax burden on our industry could have a material, negative impact on our results of operations and our cash flows. Other elements of this legislation, such as comparative effectiveness research, an independent payment advisory board, payment system reforms, including shared savings pilots, and other provisions, could meaningfully change the way health care is developed and delivered, and may materially impact numerous aspects of our business. A portion of our operations are located in a facility that may be at risk from fire, earthquakes or other disasters. Final assembly in our manufacturing process and significant portions of our inventory are located in a single facility in Poway, California, near known fire areas and earthquake fault zones. Future natural disasters could cause substantial delays in our operations and cause us to incur additional expenses. Although we have taken precautions to insure our facilities and continuing operations, as well as provide for offsite back-up of our information systems, this may not be adequate to cover our losses in any particular case. A disaster could significantly harm our business and results of operations. The medical device industry is litigious, which could result in the diversion of our management's time and efforts, and require us to pay damages which may not be covered by our insurance. Our operations entail risks of claims or litigation relating to product liability, radioactive contamination, patent infringement, trade secret disclosure, warranty claims, vendor disputes, product recalls, property damage, misdiagnosis, breach of contract, personal injury, and death. Any litigation or claims against us, or claims we bring against others, may cause us to incur substantial costs, could place a significant strain on our financial resources, divert the attention of our management from our core business and harm our reputation. We may incur significant liability in the event of any such litigation, regardless of the merit of the action. If we are unable to obtain insurance, or if our insurance is inadequate to cover claims, our cash reserves and other assets could be negatively impacted. Additionally, costs associated with maintaining our insurance could become prohibitively expensive, and our ability to become or remain profitable could be diminished. Our ability to protect our intellectual property and proprietary technology through patents and other means is uncertain. Our success depends, in part, on our ability to protect our proprietary rights to the technologies used in our products. Any patents we have obtained or do obtain may be challenged by re-examination or otherwise invalidated or eventually found unenforceable. Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may attempt to challenge or invalidate our patents, or may be able to design alternative techniques or 12 devices that avoid infringement of our patents, or develop products with functionalities that are comparable to ours. In the event a competitor infringes upon our patent or other intellectual property rights, litigation to enforce our intellectual property rights or to defend our patents against challenge, even if successful, could be expensive and time consuming and could require significant time and attention from our management. We may not have sufficient resources to enforce our intellectual property rights or to defend our patents against challenges from others. We adopted a tax benefits preservation plan, designed to preserve the value of certain income tax assets, primarily tax net operating loss carryforwards (“NOLs”), which may discourage acquisition and sale of large blocks of our stock and may result in significant dilution for certain stockholders. In May 2013, we adopted a tax benefits preservation plan in the form of a Section 382 Rights Agreement (the “382 Agreement”). The 382 Agreement is designed to preserve stockholder value and the value of certain income tax assets primarily associated with NOLs by acting as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s outstanding common stock without the approval of the Board. The 382 Agreement may discourage existing 5% stockholders from selling their interest in a single block which may impact the liquidity of the Company's common stock, may deter institutional investors from investing in our stock, and may deter potential acquirers from making premium offers to acquire the Company, factors which may depress the market price of our stock. Anti-takeover provisions in our organizational documents, our Stockholders Rights Plan and Delaware law may prevent or delay removal of current management or a change in control. Our restated certificate of incorporation and restated bylaws contain provisions that may delay or prevent a change in control, discourage bids at a premium over the market price of our common stock, and adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock. The rights issued pursuant to our Stockholder Rights Plan will become exercisable, subject to certain exceptions, the tenth day after a person or group announces acquisition of 20% or more of our common stock or announces commencement of a tender or exchange offer, the consummation of which would result in ownership by the person or group of 20% or more of our common stock. In addition, as a Delaware corporation, we are subject to Delaware law, including Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder unless certain specific requirements are met as set forth in Section 203. These provisions, alone or together, could have the effect of deterring or delaying changes in incumbent management, proxy contests or changes in control. 13 ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES Our principal executive offices are located in an approximately 8,500 square foot facility in Suwanee, Georgia that is leased to us on a month to month basis. Our former corporate headquarters were located in an approximately 47,000 square foot facility in Poway, California. Consistent with our facilities restructuring initiative, on January 22, 2014, we entered into a termination agreement to end the lease on the 47,000 square foot Poway, California facility as of April 30, 2014. The original term of the lease would have continued through February 29, 2016. Concurrently with the termination of the lease for the 47,000 square foot Poway, California facility, we entered into a new lease agreement on January 23, 2014 for a separate 21,300 square foot facility in Poway, California to house our Diagnostic Imaging operations. The new lease agreement is for the term from March 1, 2014 through February 28, 2021. See Note 10 to the audited consolidated financial statements for further information. In addition to the aforementioned properties, DIS leases approximately 24 additional small hub locations in the various states in which we operate, which primarily house our fleet of cameras and vans. The hub location lease terms typically range between one and five years. ITEM 3. LEGAL PROCEEDINGS See Note 6 to the audited consolidated financial statements for a summary of legal proceedings.

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Market Information Our common stock is traded on the NASDAQ Global Market under the symbol "DRAD". The following table presents the high and low per share sale prices of our common stock during the periods indicated, as reported on NASDAQ. First Quarter Second Quarter Third Quarter Fourth Quarter Year ended December 31, 2013 2012 High Low High Low $ $ 2.53 2.68 2.84 4.85 $ 1.80 2.16 2.32 2.50 $ 2.18 2.37 2.21 2.22 1.81 1.99 1.90 1.95 As of March 13, 2014 there were approximately 196 holders of record of our common stock. We believe that the number of beneficial owners is substantially greater than the number of record holders because a large portion of our common stock is held of record through brokerage firms in "street name." Dividend Policy We paid our first cash dividend on common stock of $0.05 per common share on November 22, 2013. Subsequently on February 3, 2014, we announced a dividend of $0.05 per common share payable on February 24, 2014 to shareholders of record as of February 14, 2014. We presently intend to continue the payment of regular quarterly cash dividends on our common stock. Our ability to pay dividends could be affected by future business performance, liquidity, and capital needs. Sales of Unregistered Securities None. Issuer Purchases of Equity Securities There were no issuer purchases of equity securities during the fourth quarter of fiscal year 2013. On February 27, 2013, our board of directors modified our stock buyback program originally adopted in February 2009 to increase repurchases to an aggregate of $7.0 million, and subsequently, on March 13, 2013, increased the stock buyback program again for repurchases of up to an aggregate of $12.0 million. The timing of stock repurchases and the number of shares of common stock to be repurchased are in compliance with Rule 10b-18 under the Securities Exchange Act of 1934. The timing and extent of the repurchase depends upon market conditions, applicable legal and contractual requirements, and other factors.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion contains forward-looking statements which involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth previously under the caption “Risk Factors.” This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our audited consolidated financial statements and related notes included elsewhere in this report. Overview We are one of the largest national providers of in-office nuclear cardiology imaging and ultrasound services to physician practices, hospitals and imaging centers through our Digirad Imaging Solutions (“DIS”) business segment. We also sell medical diagnostic imaging systems including solid-state gamma cameras for nuclear cardiology and general nuclear medicine applications, as well as provide service on the products we sell through our Diagnostic Imaging segment. We designed and commercialized the first solid-state nuclear gamma camera for the detection of cardiovascular disease and other medical conditions. Our imaging systems are sold in both portable and fixed configurations, and provide enhanced operability and improved patient comfort. Our nuclear cameras fit easily into floor spaces as small as seven feet by eight feet and facilitate the delivery of nuclear medicine procedures in a physician’s office, an outpatient hospital setting or within multiple departments of a hospital, (e.g., emergency and operating rooms). We generate revenues within two primary operating segments: DIS and Diagnostic Imaging. Through DIS, we offer a convenient and economically efficient imaging services program as an alternative to purchasing a gamma camera or ultrasound equipment or outsourcing the procedures to another physician or imaging center. For physicians who wish to perform nuclear imaging, echocardiography, vascular or general ultrasound tests, or any combination of these procedures in their offices, we provide the ability for them to engage our services, which includes the use of our imaging system, qualified personnel, and related items required to perform imaging in the their own offices and bill Medicare, Medicaid or one of the third-party healthcare insurers directly for those services. These services are also used by large and small hospitals, multi-practice physician groups, and imaging centers. The flexibility of our products and our DIS service allows physicians to ensure continuity of care and convenience for their patients and allows them to retain revenue from procedures they would otherwise refer to imaging centers and hospitals. DIS services are primarily provided to cardiologists, internal medicine physicians, and family practice doctors who enter into annual contracts for a set number of days ranging from once per month to five times per week. We experience some seasonality in our DIS business related to vacations, holidays, and inclement weather. Most of the DIS business focuses on cardiac care with an increase in the combination of cardiac, vascular and general ultrasound imaging in recent months. Many of the physicians who use DIS services are reliant on reimbursements from Medicare and third-party insurers where there has been downward pressure and uncertainty due to factors outside the physicians’ control. The uncertainty created by the 2010 healthcare reform laws, Congress’ continued deferred action on the Sustainable Growth Rate reimbursement factor (which is part of the Relative Value Unit calculation of reimbursements for all medical codes associated with the physician fee schedule) and other legislation has also impacted our business. These changes may require further modifications to our business model in order for our physician customers and us to maintain a viable economic model. Our Diagnostic Imaging segment revenue results primarily from selling solid-state gamma cameras and camera maintenance contracts. We sell our imaging systems to physician offices and hospitals primarily in the United States, although we have sold a small number of imaging systems internationally. For many years since our Initial Public Offering in 2004, we have focused significant efforts on research and development activities to develop and further enhance our nuclear imaging cameras, primarily for alternative uses within the health care environment. These efforts, along with a fixed infrastructure that was sized for a much higher volume of manufacturing and sales of our nuclear imaging cameras than we have experienced, has resulted in several years of financial losses. On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly reduce costs and improve profitability. With this restructuring, we are focusing our efforts on growing our DIS services business, while at the same time continuing to sell and service our cameras, but at a more profitable level, and with a vastly modified infrastructure. We believe that our cameras have underlying technology and related patents that make them relevant for many years into the future, negating the need for a fixed cost research and development infrastructure. Our Market The target market for our products and services is comprised of cardiologists, internal medicine physicians, family practice physicians, and hospitals in the United States that perform or could perform nuclear and ultrasound diagnostic imaging procedures. During the year ended December 31, 2013, we provided imaging services through DIS to 545 physicians and physician groups. 18 More than half of our DIS nuclear and ultrasound diagnostic imaging customers are internal medicine physicians or other primary care practitioners, and the remainder are primarily cardiologists. As discussed earlier, our market has been negatively affected by lower physician reimbursements from the Center for Medicare and Medicaid Services (CMS) and third party insurance providers for the codes under which our physician customers bill for our services. We have been addressing, and will continue to address, these market pressures by modifying our DIS business model, and assisting our physician customers in complying with new regulations and requirements. Trends and Drivers The medical device industry, including the market for nuclear and ultrasound imaging systems and services, is highly competitive. Our business continues to be affected by many factors, including healthcare reimbursement rates for cardiac imaging procedures, competition from alternative imaging modalities such as positron emission tomography (PET) and computed tomography (CT) angiography, competition from other small owner-operated mobile nuclear imaging providers and general uncertainty in the healthcare marketplace. We continue to experience market changes due to the fluctuations in reimbursement rates and the uncertainty of healthcare legislation. We expect most of these trends to continue in the foreseeable future. In our DIS segment, our physician customers continue to experience significant uncertainty in reimbursements from CMS and third party insurance providers for the codes under which our physician customers bill for our services. This uncertainty has caused some of our physician customers to sell their practices to a hospital and others to reduce the volume of our service. As a result, we are continuing to modify our offering and pricing for our services upon contract renewal. The uncertainty over the enactment of future legislation that may impact reimbursement rates continues to linger and cause concern with our physician customers. We continue to consider modification to our business model in order to adapt to environmental and regulatory changes in our dynamic healthcare marketplace. In our Diagnostic Imaging segment, we continue to focus on single photon emission computed tomography, or SPECT, products targeted specifically at the larger physician practices and hospital marketplace. The most widely used imaging acquisition technology utilizing gamma cameras is single SPECT, and all of our current cardiac gamma cameras employ SPECT technology. Despite the increasing utilization rates of competing modalities such as CT, PET and MRI, and diagnostic procedures such as CT angiography, SPECT procedures performed with gamma cameras are expected to continue to be used for a substantial number of cardiac-specific imaging procedures according to industry experts. We believe continued utilization of SPECT technology will be driven by patients having easier access to nuclear medicine services at physicians’ offices, lower purchase and maintenance costs, a smaller physical footprint, and easier service logistics of gamma cameras. In an emerging trend in cardiology, SPECT technologies are being integrated with other imaging modalities, to form hybrid imaging modalities, such as SPECT/CT, resulting in improved clinical quality and diagnostic certainty. 2013 Financial Highlights Our consolidated revenues were $49.4 million for the year ended December 31, 2013. This was a decrease of $1.1 million, or 2.3%, over the comparable prior year period primarily as a result of lower camera revenue generated from product sales in our Diagnostic Imaging business segment, partially offset by increased revenue in our DIS business segment. DIS revenue increased $1.1 million, or 3.1%, compared to the prior year period, primarily due to an increase in the number of days our physician customers utilized our imaging services, driven by the attainment of new customers, offset by a reduction in our average daily service fee rates. Diagnostic Imaging segment revenues for the year ended December 31, 2013 decreased by $2.2 million, or 15.5%, compared to the prior year period, primarily due to a decline in the volume of cameras sold as well as attrition in the number of associated camera maintenance contracts, partially offset by an increase in the average selling price of our cameras as we focused our efforts on higher margin sales. The number of cameras sold decreased to 20 from 29 during the years ended December 31, 2013 and 2012, respectively. We realized income from operations and net income for the year ended December 31, 2013 primarily as a result of increased gross profit and decreased operating expenses. Our consolidated net income for the year ended December 31, 2013 was $0.3 million, which is an increase of $5.2 million, compared to our net loss of $4.9 million during the prior year. The DIS segment generated marginal operating income as a result of increased revenue, favorable radiopharmaceutical costs and decreased depreciation, offset by higher allocations of corporate operating expense and variable compensation expense. The operating income in the Diagnostic Imaging segment was primarily attributable to favorable product mix and average selling prices, reduced excess and obsolete inventory charges as well as vastly reduced operating expenses, primarily related to a reduction in research and development expenses. There were two significant non-recurring items during the year ended December 31, 2013, which largely offset each other. We incurred approximately $1.7 million of charges associated with the Diagnostic Imaging restructuring initiative during the year ended December 31, 2013. See Note 10 to the audited consolidated financial statements for further information. Largely offsetting the impact of the restructuring initiative charges was a gain of $1.6 million related to the sale of all the assets specifically related to an uncommercialized surgical imaging system previously in development, as well as the license of certain 19 existing Company technology for use in the peri-operative field. See Note 11 to the audited consolidated financial statements for further information. Our DIS business currently operates in 19 states. For the year ended December 31, 2013, DIS operated 68 nuclear gamma cameras and 56 ultrasound imaging systems. We continue to strive to improve our overall profitability through more efficient utilization of our fleet of gamma cameras and ultrasound equipment. We measure efficiency by tracking system utilization, which is measured based on the percentage of days that our nuclear gamma cameras and ultrasound equipment are used to deliver services to customers out of the total number of days that they are available to deliver such services. System utilization increased to 63% for the year ended December 31, 2013, compared to 60% in the prior year due to an increase in the number of days our physician customers utilized our imaging services. Critical Accounting Policies Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements which are prepared in accordance with United States generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, related 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 evaluate our estimates and judgments, the most critical of which are those related to revenue recognition, multiple element arrangements, reserves for doubtful accounts and inventory valuation. 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. Revenue Recognition We derive revenues primarily from providing in-office services related to the performance of cardiac diagnostic imaging procedures and from selling and servicing solid-state digital gamma cameras. We recognize revenue in accordance with the authoritative guidance for revenue recognition, when all of the following four criteria are met: (i) a contract or sales arrangement exists; (ii) products have been shipped and title has transferred or services have been rendered; (iii) the price of the products or services is fixed or determinable; and (iv) collectability is reasonably assured. The timing of revenue recognition is based upon factors such as passage of title and risk of loss, the need for installation, and customer acceptance. These factors are based on the specific terms of each contract or sales arrangement. DIS revenue is derived from our ability to provide our physician customers with our services, which includes use of our imaging system, qualified personnel, and related items required to perform imaging in their own offices and bill Medicare, Medicaid and other payors for in-office nuclear and ultrasound diagnostic imaging procedures. Revenue related to diagnostic imaging services is recognized at the time services are performed and collection is reasonably assured. DIS diagnostic imaging services are generally billed on a per-day basis under annual contracts for nuclear diagnostic imaging, which specifies the number of days of service to be provided, or on a flat rate month-to-month basis for ultrasound imaging. Diagnostic Imaging product revenues are generated from the sales of gamma cameras and follow-on maintenance service contracts. We generally recognize revenue upon delivery and acceptance by customers. We also provide installation and training for camera sales in the United States. Installation and initial training is generally performed shortly after delivery and represents a cost which we accrue at the time revenue is recognized. Neither service is essential to the functionality of the product. Maintenance services are sold beyond the term of the warranty, which is generally one year from the date of purchase. Revenue from these contracts is deferred and recognized ratably over the period of the obligation and is included in Diagnostic Imaging product sales. Multiple Element Arrangements In fiscal year 2013, we sold all of our assets specifically related to an uncommercialized surgical imaging system previously in development, as well as licensed certain existing Company technology. The transaction was accounted for in accordance with the authoritative guidance for multiple element arrangements. We identified the deliverables at the inception of the agreement and determined which items had value to the customer on a standalone basis, and were therefore separate units of accounting. Non- contingent arrangement consideration was allocated at the inception of the agreement to all identified units of accounting based on their relative selling price. The relative selling price for each unit of accounting was determined using best estimate of selling price, because neither vendor specific objective evidence, or VSOE, of selling price or third-party evidence of selling price existed for the units of accounting. The non-contingent amount of arrangement consideration allocated to each unit of account was recognized upon performance and delivery of the related unit of accounting. Allowance for Doubtful Accounts and Billing Adjustments We provide reserves for billing adjustments and doubtful accounts. We review reserves on a quarterly basis and make adjustments based on our historical experience rate and known collectability issues and disputes. We also consider our bad debt write-off and 20 billing adjustments history. Our estimates of collectability could be impacted by material amounts due to changed circumstances, such as a higher number of defaults or material adverse changes in a payor’s ability to meet its obligations. Within DIS, we record adjustments and credit memos that represent billing adjustments subsequent to the performance of service. A provision for billing adjustments is charged against DIS revenues and a provision for doubtful accounts is charged to general and administrative expenses. Inventory We state inventories at the lower of cost (first-in, first-out) or market (net realizable value) and review our inventory balances for excess and obsolete inventory levels on a quarterly basis. Costs include material, labor and manufacturing overhead and variance costs. We rely on historical information to support our reserve and utilize management’s business judgment. Per our policy, we generally reserve 100% of the cost of inventory quantities in excess of a defined period of demand. Once inventory is reserved, we do not adjust the reserve balance until the inventory is sold or disposed. Fair-value of Financial Instruments The authoritative guidance for fair value measurements defines fair value for accounting purposes, establishes a framework for measuring fair value and provides disclosure requirements regarding fair value measurements. The guidance defines fair value as an exit price, which is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and require less judgment in measuring fair value. Conversely, assets and liabilities that are rarely traded or not quoted have less pricing observability and are generally measured at fair value using valuation models that require more judgment. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency of the asset, liability or market and the nature of the asset or liability. We have categorized our assets and liabilities measured at fair value into a three-level hierarchy in accordance with this guidance. See Note 4 for a further discussion regarding our measurement of assets and liabilities at fair value. Valuation of Long-Lived Assets including Finite Lived Purchased Intangible Assets Long-lived assets consist of property and equipment and finite lived intangible assets. We record property and equipment at cost, and record other intangible assets based on their fair values at the date of acquisition. We calculate depreciation on property and equipment using the straight-line method over the estimated useful life of the assets. Charges related to amortization of assets recorded under capital leases is included within depreciation expense. We calculate amortization on other intangible assets using either the accelerated or the straight-line method over the estimated useful life of the assets, based on the nature of when we expect to receive cash inflows generated by the intangible assets. Impairment losses on long-lived assets used in operations are recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. When indicators of impairment exist, we perform a review of the carrying value of our long-lived assets to be held and used, including certain identifiable intangible assets. No impairment losses were recorded on long-lived assets during the years ended December 31, 2013, 2012 or 2011. Valuation of Goodwill We review goodwill for impairment on an annual basis during the fourth quarter, as well as when events or changes in circumstances indicate that the carrying value may not be recoverable. We begin the process by assessing qualitative factors in determining whether it is more likely than not that the fair value of our reporting unit is less than its carrying amount. After performing the aforementioned assessment and upon review of the results of such assessment, we may begin performing step one of the two-step impairment analysis by quantitatively comparing the fair value of the reporting unit with goodwill to the carrying value of its long-term assets. If the carrying value of the long-term assets exceeds the fair value of the reporting unit, then we must perform the second step of the impairment test, whereby the carrying value of the reporting unit’s goodwill is compared to its implied fair value. If the carrying value of the goodwill exceeds the implied fair value, an impairment loss equal to the difference would be recorded. No impairment losses were recorded on goodwill during the years ended December 31, 2013, 2012 or 2011. Restructuring Restructuring costs are included in income (loss) from operations within the consolidated statements of comprehensive income (loss). Losses on property and equipment are recorded consistent with our accounting policy related to long-lived assets. One- 21 time termination benefits are recorded at the time they are communicated to the affected employees. Losses on property lease obligations are recorded when the lease is abandoned or terminated. On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business. In addition, on January 27, 2014, we announced a plan to exit our 47,000 square foot former headquarters facility in Poway, California. See Note 10 to the audited consolidated financial statements. Share-Based Compensation We grant options to purchase our common stock and restricted stock units (“RSUs”) to our employees and directors under our equity compensation plans. We estimate the fair value of the stock option awards using the Black-Scholes option-pricing model on the date of grant. The fair value of RSUs is based on the stock price on the date of grant. The fair value of equity instruments that are expected to vest are recognized using the straight-line method over the requisite service period. We estimated the forfeiture rate based on historical data for forfeitures and we are recognizing compensation costs only for those equity awards expected to vest. Warranty We generally provide a 12 month warranty on our cameras. We accrue the estimated cost of this warranty at the time revenue is recorded and charge warranty expense to Diagnostic Imaging cost of revenues. Warranty reserves are established based on historical experience with failure rates and repair costs and the number of systems covered by warranty. Warranty reserves are depleted as cameras are repaired. The costs consist principally of materials, personnel, overhead and transportation. We review warranty reserves quarterly and, if necessary, make adjustments. Income Taxes We account for income taxes in accordance with the related authoritative guidance, which sets forth an asset and liability approach that requires the recognition of deferred tax assets and deferred tax liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that is more likely than not expected to be realized. In making such a determination, a review of all available positive and negative evidence must be considered, including scheduled reversal of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. The authoritative guidance for income taxes defines a recognition threshold and measurement attributes for financial statement recognition and measurement of a tax provision taken or expected to be taken in a tax return. The guidance also provides direction on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under the guidance, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more- likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. We recognize interest and penalties related to uncertain tax positions as a component of the income tax provision.

Consolidated revenue was $49.4 million for the year ended December 31, 2013, a decrease of $1.1 million, or 2.3%, from the prior year, primarily as a result of lower camera revenue generated from product sales in our Diagnostic Imaging business segment, partially offset by increased revenue in our DIS business segment. DIS revenue accounted for 75.3% of total revenues for the year ended December 31, 2013, compared to 71.4% for the prior year. We expect DIS revenue to continue to represent the larger percentage of our consolidated revenue. DIS. Our DIS revenue was $37.2 million for the year ended December 31, 2013, an increase of $1.1 million, or 3.1%, from the prior year period. The increase is attributable to growth in the number of days our physician customers utilized our imaging services driven by the attainment of new customers, partially offset by a decline in our daily service fee. Diagnostic Imaging. Our Diagnostic Imaging revenue was $12.2 million for the year ended December 31, 2013, a decrease of $2.2 million, or 15.5%, compared to the prior year period, primarily due to a decline in the volume of cameras sold as well as attrition in the number of associated camera maintenance contracts. The number of cameras sold decreased to 20 from 29 during the year ended December 31, 2013 and 2012, respectively, as a result of focusing on the profit margin of camera sales in fiscal year 2013 with reduced emphasis on the total volume of sales. The decrease in the volume of camera sales was partially offset by an increase in the average selling price per camera during the year ended December 31, 2013 as compared to the prior year. Cost of Revenue and Gross Profit Consolidated. Consolidated gross profit was $14.1 million for the year ended December 31, 2013, an increase of $1.0 million, or 7.8%, compared to the prior year. The increase in consolidated gross profit is primarily the result of increased gross profit generated in our DIS business segment, resulting from increased revenue and favorable radiopharmaceutical costs. Our Diagnostic Imaging business segment benefited from lower excess and obsolete inventory costs for the year ended December 31, 2013, compared to the prior year. Significant excess and obsolete inventory costs were incurred during the year ended December 31, 2012 as a result of the Diagnostic Imaging restructuring initiative. Consolidated gross profit as a percentage of revenue increased to 28.6% for the year ended December 31, 2013 from 25.9% for the prior year. DIS. Cost of DIS revenue consists of labor, radiopharmaceuticals, equipment depreciation, and other costs associated with the provision of services. Cost of DIS revenue was $27.8 million for the year ended December 31, 2013, an increase of $0.5 million, or 2.0%, from the prior year period, primarily as a result of increased revenues partially offset by lower radiopharmaceutical costs and depreciation expense. DIS gross profit was $9.3 million for the year ended December 31, 2013, an increase of $0.6 million, or 6.5%, as compared to the prior year period. DIS gross profit as a percentage of DIS revenue increased to 25.1% for the year ended December 31, 2013 from 24.3% for the prior year due to lower radiopharmaceutical costs, depreciation expense and an improvement in operational performance primarily associated with the management of resources. Diagnostic Imaging. Cost of Diagnostic Imaging segment revenue primarily consists of materials, labor and overhead costs associated with the manufacturing and warranty of our products. Cost of Diagnostic Imaging revenues was $7.4 million for the year ended December 31, 2013, a decrease of $2.7 million, or 26.6%, over the prior year period, primarily as a result of the reduced volume of camera sales and approximately $1.0 million less of excess and obsolete inventory costs year over year. Diagnostic Imaging gross profit was $4.8 million for the year ended December 31, 2013, an increase of $0.5 million, or 10.5% as compared to the prior year period. Diagnostic Imaging gross profit as a percentage of Diagnostic Imaging revenue increased to 39.1% for the year ended December 31, 2013 from 29.9% for the prior year primarily due to reduced excess and obsolete inventory costs and improved average selling prices and product mix for cameras. Operating Expenses Research and Development. Research and development expenses are the costs associated with the design, development and expansion of our existing technology and consist of salaries, development material costs, facility and overhead costs, consulting fees, and non-recurring engineering costs. Research and development expenses were $1.0 million for the year ended December 31, 2013, representing a decrease of $2.7 million, or 72.4% compared to the prior year. The decrease is due to our Diagnostic Imaging restructuring initiative, which focuses on our existing camera product offerings rather than continued development of new product offerings with alternative applications. We believe our current product line has a technological advantage over competing products and continued relevance well into the future. We expect that research and development expense for fiscal year 2014 will be lower than in fiscal year 2013. On a go forward basis, we plan to primarily utilize outside service providers for research and development services on an as needed basis for updates and enhancements, with the amount of corresponding expenditure fluctuating commensurately quarter by quarter. Research and development expenses were 8.4% and 25.7% of Diagnostic Imaging revenue for the years ended December 31, 2013 and 2012, respectively. 24 Marketing and Sales. Marketing and sales expenses consist primarily of salaries, commissions, bonuses, recruiting costs, travel, marketing and collateral materials and trade show costs. Marketing and sales expenses were $4.4 million for the year ended December 31, 2013, a decrease of $2.0 million, or 31.1%, compared to the prior year, primarily as a result of the Diagnostic Imaging restructuring initiative. Marketing and sales expenses as a percentage of total revenues were 8.9% and 12.7% for the years ended December 31, 2013 and 2012, respectively. We expect that marketing and sales expense for fiscal year 2014 will be relatively consistent with fiscal year 2013. General and Administrative. General and administrative expenses consist primarily of salaries and other related costs for accounting, human resources, information technology and executive personnel, legal related costs, professional fees, outside services, insurance, and costs related to our board of directors. General and administrative expenses were $8.1 million for the year ended December 31, 2013, an increase of $0.3 million, or 3.6%, compared to the prior year, primarily as a result of costs associated with our 2013 proxy contest and the subsequent legal proceedings associated with the proxy contest, as well as higher variable compensation expense associated with Company performance. The aforementioned increases in general and administrative expense for the year ended December 31, 2013 as compared to the prior year, were offset by decreases in human resources, information technology, and bad debt expenses. General and administrative expenses were 16.4% of total revenue for the year ended December 31, 2013 compared to 15.5% for the prior year. On a go forward basis, we expect general and administrative expense to generally approximate the level of expense noted in the year ended December 31, 2013 notwithstanding any one-time initiatives. Restructuring. On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly reduce costs, including a reduction in force (the "Diagnostic Imaging restructuring initiative"). In September 2013, as part of the restructuring initiative, we entered into an agreement with a third party to outsource the majority of the manufacturing related to our cameras. After completion of the Diagnostic Imaging restructuring initiative, we believe the overall operating cash flow of the Company will increase. Overall, this restructuring resulted in total charges of $1.7 million being incurred in fiscal year 2013. These charges consisted primarily of employee related costs. We expect incremental restructuring charges related to the termination of the lease for the former headquarters facility located in Poway, California, to be incurred in the first half of fiscal 2014, as well as minimal employee related costs associated with the Diagnostic Imaging restructuring initiative. See Note 10 to the consolidated financial statements for further information. Gain on sale of assets and license agreement. On July 31, 2013, we entered into an asset purchase agreement with Novadaq Technologies Inc. (“Novadaq”). Under the terms of the asset purchase agreement, we sold Novadaq all of our assets specifically related to an uncommercialized surgical imaging system previously in development. We also licensed certain existing Company technology to Novadaq for their use in the peri-operative field. In exchange, we received upfront consideration of $2.0 million, and could receive up to $1.0 million in deferred contingent payments based on the achievement of specific regulatory and commercial milestones as well as a royalty on sales, if any. A gain of $1.6 million representing the $2.0 million of upfront consideration less legal, consulting and other transaction fees as well as the cost basis of the inventory was recorded during the year ended December 31, 2013. The sale of the technology is consistent with our focus on our existing camera product offerings, rather than development of completely new product offerings. Comparison of Years Ended December 31, 2012 and 2011 Revenues Consolidated. Consolidated revenue was $50.5 million for the year ended December 31, 2012, a decrease of $3.2 million, or 6.0%, from the prior year period, primarily as a result of a reduction in revenue generated from our DIS business segment and lower camera revenue generated from product sales in our Diagnostic Imaging business segment. DIS revenue accounted for 71.4% of total revenues for the year ended December 31, 2012, compared to 70.3% for prior year period. DIS. Our DIS revenue was $36.1 million for the year ended December 31, 2012, a decrease of $1.7 million, or 4.6%, from the prior year period. The decrease resulted from a reduction in the number of days our physician customers utilized our imaging services and a decline in our daily service fee. Diagnostic Imaging. Our Diagnostic Imaging revenue was $14.4 million for the year ended December 31, 2012, a decrease of $1.5 million, or 9.4%, compared to the prior year period, primarily due to the mix of camera products which were sold to cardiology practices and hospitals.The number of cameras sold increased to 29 from 27 during the year ended December 31, 2012 and 2011, respectively. Cost of Revenue and Gross Profit Consolidated. Consolidated gross profit was $13.1 million for the year ended December 31, 2012, a decrease of $1.7 million, or 11.3%, compared to the prior year period. The decrease in consolidated gross profit is primarily the result of the mix in camera product sales from our Diagnostic Imaging business segment, increased excess and obsolete inventory costs as a result of the Diagnostic Imaging restructuring initiative and fewer imaging days in our DIS business segment, partially offset by lower 25 radiopharmaceutical costs.Consolidated gross profit as a percentage of revenue decreased to 25.9% for the year ended December 31, 2012 from 27.5% for the prior year period. DIS. Cost of DIS revenue was $27.3 million for the year ended December 31, 2012, a decrease of $2.4 million, or 8.0%, from the prior year period, primarily as a result of decreased revenues and lower radiopharmaceutical costs. DIS gross profit was $8.8 million for the year ended December 31, 2012, an increase of $0.6 million, or 8.0% as compared to the prior year period. DIS gross profit as a percentage of DIS revenue increased to 24.3% for the year ended December 31, 2012 from 21.5% for the prior year due to lower radiopharmaceutical costs and an improvement in operational performance primarily associated with the management of resources. Diagnostic Imaging. Cost of Diagnostic Imaging revenues was $10.1 million for the year ended December 31, 2012, an increase of $0.8 million, or 8.7%, over the prior year period. Diagnostic Imaging gross profit was $4.3 million for the year ended December 31, 2012, a decrease of $2.3 million, or 34.9% as compared to the prior year period. Diagnostic Imaging gross profit as a percentage of Diagnostic Imaging revenue decreased to 29.9% for the year ended December 31, 2012 from 41.6% for the prior year due to changes in camera product mix and increased excess and obsolete inventory costs as a result of the Diagnostic Imaging restructuring initiative. Operating Expenses Research and Development. Research and development expenses were $3.7 million for the year ended December 31, 2012, representing an increase of $1.0 million, or 35.7%, compared to the prior year period mainly due to initiatives to explore and develop new products and technologies. Research and development expenses were 25.7% and 17.2% of Diagnostic Imaging revenue for the years ended December 31, 2012 and 2011, respectively. Marketing and Sales. Marketing and sales expenses were $6.4 million for the year ended December 31, 2012, a decrease of $1.2 million, or 16.0%, compared to the prior year period, primarily as a result of lower personnel related costs and marketing support costs. Marketing and sales expenses as a percentage of total revenues were 12.7% and 14.2% for the years ended December 31, 2012 and 2011, respectively. General and Administrative. General and administrative expenses were $7.8 million for the year ended December 31, 2012, an increase of $0.1 million, or 1.3%, compared to the prior year. General and administrative expenses were 15.5% of total revenue for the year ended December 31, 2012 compared to 14.4% for the prior year. Liquidity and Capital Resources Overview We generated $2.2 million of positive cash flow from operations during the year ended December 31, 2013, and expect to continue to generate positive cash flow from operations on an annual basis in the future. Cash flows from operations primarily represent inflows from net income (adjusted for depreciation, amortization and other non-cash items) as well as the net effect of changes in working capital. Cash flows from investing activities primarily represent our investment in capital equipment required to grow our business, as well as acquisition and divestiture activity. Cash flows from financing activities primarily represent outflows related to our share repurchase program and recently initiated dividend payment, offset by the receipt of cash related to the exercise of stock options. Our principal sources of liquidity are our existing cash and cash equivalents, short-term investments, and cash generated from operations. As of December 31, 2013, we had cash, cash equivalents and securities available-for-sale of $26.4 million. We generally invest our cash reserves in money market funds, U.S. treasury and corporate debt securities. We require capital principally for capital expenditures, share repurchases, dividend payments and to finance accounts receivable and inventory, which we manage closely. Our working capital requirements vary from period to period depending on inventory requirements, the timing of deliveries and the payment cycles of our customers. Our capital expenditures consist primarily of nuclear cameras, ultrasound machines, vans, and computer hardware and software. We paid our first cash dividend on common stock of $0.05 per share on November 22, 2013, and presently intend to continue the payment of regular quarterly cash dividends. We are authorized under our stock buyback program for total repurchases of up to an aggregate of $12.0 million. During the year ended December 31, 2013, we repurchased 1,514,843 shares of our common stock under the stock buyback program at a total cost of $3.6 million. As of December 31, 2013, an aggregate of $6.3 million remains authorized for stock buyback under the program.We expect to manage the pace of repurchases under this program based on market conditions and other relevant factors. Based upon our current level of expenditures and anticipated financing activities, we believe our existing cash and cash equivalents, together with our anticipated cash flows from operating activities, will be adequate to meet our anticipated cash requirements for at least the next 12 months. 26 Cash Flows The following table shows cash flow information for the years ended December 31, 2013, 2012 and 2011 (in thousands): Years Ended December 31, Net cash provided by (used in) operating activities Net cash provided by (used in) investing activities Net cash provided by (used in) financing activities Operating Activities 2012 2011 2013 2,201 $ 766 $ $ (3,737) $ $ (1,082) $ $ (2,715) $ (728) $ 965 2,515 100 Net cash provided by operating activities increased by $3.3 million for the year ended December 31, 2013 compared to the prior year period. The increase was primarily attributable to net income of $0.3 million generated in fiscal year 2013, driven by improved gross profit and vastly reduced operating expenses, compared to the net loss of (4.9) million generated in fiscal year 2012. In addition, we benefited from favorable changes in operating assets and liabilities in fiscal year 2013 primarily related to decreases in accounts receivable and inventory, and an increase in accrued compensation. Net cash used in operating activities increased by $2.0 million for the year ended December 31, 2012 compared to the prior year period. This increase was primarily related to the increase in net loss and decreases in non-cash charges related to depreciation, amortization of intangible assets and stock based compensation. Investing Activities Net cash provided by investing activities increased by $3.5 million for the year ended December 31, 2013 compared to the prior year period. The increase is attributable to $1.7 million of net proceeds received from the sale of assets related to an uncommercialized surgical imaging system and associated license agreement in fiscal year 2013, as well as reduced net purchases of securities available-for-sale in fiscal year 2013 compared to fiscal year 2012. Net cash used in investing activities increased $5.2 million for the year ended December 31, 2012 compared to the prior year period. The increase is primarily attributable to increased net investments in securities available for sale, as well as $0.5 million of cash used to acquire the operating assets of a nuclear and ultrasound imaging business located in the Southeastern U.S. in fiscal year 2012. Financing Activities Net cash used in financing activities increased by $3.0 million for the year ended December 31, 2013 compared to the prior year period. This increase was primarily attributable to increased repurchases of common stock and the initiation of a cash dividend on common stock, partially offset by proceeds from stock option exercises driven by employees that were terminated as a result of the Diagnostic Imaging restructuring initiative. Net cash used in financing activities increased by $0.8 million for the year ended December 31, 2012 compared to the prior year period. This increase was primarily attributable to repurchases of common stock. Contractual Obligations We are committed to making future cash payments on capital leases (including interest) and operating leases. We have not guaranteed the debt of any other party. The following table summarizes our contractual obligations as of December 31, 2013 (amounts in thousands): Contractual Obligations Payments Due by Period Total Less than 1 year 1-3 years 3-5 years More than 5 years Operating lease obligations(1) Capital lease obligations(2) Total Contractual Obligations $ (1) Operating lease obligations do not reflect the impact of the termination of the former headquarters lease in Poway, California, and subsequent entry into a lease for a separate 21,300 square foot facility in Poway, California. Both of the aforementioned events occurred subsequent to December 31, 2013. Refer to Note 10 of the consolidated financial statements for further detail.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Our exposure to market risk due to changes in interest rates relates primarily to the increase or decrease in the value of debt securities in our investment portfolio. Our risk associated with fluctuating interest rates is limited to our investments in interest rate sensitive financial instruments. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. We attempt to increase the safety and preservation of our invested principal funds by limiting default risk, market risk and reinvestment risk. We mitigate default risk by investing in investment grade securities. A 100 basis point adverse move in interest rates along the entire interest rate yield curve would not materially affect the fair value of our interest sensitive financial instruments. Changes in interest rates over time will increase or decrease our interest income. 28 ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders of Digirad Corporation We have audited the accompanying consolidated balance sheets of Digirad Corporation as of December 31, 2013 and 2012, and the related consolidated statements of comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

The Company Digirad Corporation (“Digirad”), a Delaware corporation, is one of the largest national providers of in-office nuclear cardiology imaging and ultrasound services to physician practices, hospitals and imaging centers through our Digirad Imaging Solutions (“DIS”) segment. Through DIS, we provide in-office imaging services to physicians, offering certified personnel, required licensure, an imaging system and other support and supplies for the performance of nuclear and ultrasound imaging procedures under the supervision of our physician customers. DIS' physician customers enter into service contracts for imaging services generally delivered on a per-day basis. We also sell medical diagnostic imaging systems including solid-state gamma cameras for nuclear cardiology and general nuclear medicine applications, as well as provide service on the products we sell through our Diagnostic Imaging segment. These two reportable segments, DIS and Diagnostic Imaging, are collectively referred to herein as the “Company.” The accompanying consolidated financial statements include the operations of both segments. Intercompany accounts and transactions are accounted for at cost and have been eliminated in consolidation. All our long-lived assets are located in the United States and substantially all of our revenues arise from sales activity in the United States. NOTE 2. Basis of Presentation and Significant Accounting Policies Basis of Presentation The consolidated financial statements are prepared in conformity with United States generally accepted accounting principles ("GAAP") and include the financial statements of the Company and its wholly owned subsidiaries. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results could differ from management’s estimates. All significant intercompany accounts and transactions have been eliminated. In addition certain reclassifications have been made to the prior year financial statements to conform to the current period presentation. Revenue Recognition We derive revenue primarily from providing in-office services to support the performance of cardiac diagnostic imaging procedures and from selling and servicing solid-state digital gamma cameras. We recognize revenue in accordance with the authoritative guidance for revenue recognition, when all of the following four criteria are met: (i) a contract or sales arrangement exists; (ii) products have been shipped and title has transferred or services have been rendered; (iii) the price of the products or services is fixed or determinable; and (iv) collectability is reasonably assured. The timing of revenue recognition is based upon factors such as passage of title and risk of loss, the need for installation, and customer acceptance. These factors are based on the specific terms of each contract or sales arrangement. DIS revenue is derived from our ability to provide our physician customers with our services, which includes use of our imaging system, qualified personnel, and related items required to perform imaging in their own offices and bill Medicare, Medicaid and other payors for in-office nuclear and ultrasound diagnostic imaging procedures. Revenue related to diagnostic imaging services is recognized at the time services are performed and collection is reasonably assured. DIS diagnostic imaging services are generally billed on a per-day basis under annual contracts for nuclear diagnostic imaging, which specifies the number of days of service to be provided, or on a flat rate month-to-month basis for ultrasound imaging. Diagnostic Imaging segment revenue is generated from the sales of gamma cameras and follow-on maintenance service contracts. We generally recognize revenue upon delivery and acceptance by customers. We also provide installation and training for camera sales in the United States. Installation and initial training services are generally performed shortly after delivery and represent costs which are accrued at the time revenue is recognized. Neither service is essential to the functionality of the product. Maintenance services are sold beyond the term of the warranty, which is generally one year from the date of purchase. Revenue from these contracts is deferred and recognized ratably over the service period and is included in Diagnostic Imaging sales. Multiple Element Arrangements In fiscal year 2013, we sold all of our assets specifically related to an uncommercialized surgical imaging system previously in development, as well as licensed certain existing Company technology. The transaction was accounted for in accordance with the authoritative guidance for multiple element arrangements. We identified the deliverables at the inception of the agreement and determined which items had value to the customer on a standalone basis, and were therefore separate units of accounting. Non- 34 contingent arrangement consideration was allocated at the inception of the agreement to all identified units of accounting based on their relative selling price. The relative selling price for each unit of accounting was determined using best estimate of selling price, because neither vendor specific objective evidence, or VSOE, of selling price or third-party evidence of selling price existed for the units of accounting. The non-contingent amount of arrangement consideration allocated to each unit of account was recognized upon performance and delivery of the related unit of accounting. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and disclosures made in the accompanying notes to the consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, multiple element arrangements, reserves for doubtful accounts and inventory valuation. Actual results could differ from those estimates. Concentration of Credit Risk and Significant Customers Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, short-term investments and accounts receivable. We limit our exposure to credit loss by placing our cash and investments in high credit quality financial institutions and investment grade corporate debt securities. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity. No single customer represented greater than ten percent of our sales for any of the years presented. Fair Value of Financial Instruments The authoritative guidance for fair value measurements defines fair value for accounting purposes, establishes a framework for measuring fair value and provides disclosure requirements regarding fair value measurements. The guidance defines fair value as an exit price, which is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Our financial instruments primarily consist of cash equivalents, securities available-for-sale, accounts receivable, other current assets, restricted cash, accounts payable and other current liabilities. The carrying amount of these financial instruments generally approximate fair value due to their short term nature. Securities available-for-sale are recorded at fair value. Cash and Cash Equivalents We consider all investments with a maturity of three months or less when acquired to be cash equivalents. Securities Available-for-Sale Securities available-for-sale primarily consist of investment grade corporate debt securities. We classify all securities as available-for-sale and as current assets, as the sale of such securities may be required prior to maturity to execute management strategies. These securities are carried at fair value, with the unrealized gains and losses reported as a component of accumulated other comprehensive income (loss) in stockholders' equity until realized. Realized gains and losses from the sale of available-for- sale securities, if any, are determined on a specific identification basis. A decline in the market value of any available-for-sale security below cost that is determined to be other than temporary will result in an impairment charge to earnings and a new cost basis for the security is established. No such impairment charges were recorded for any period presented. It is not more likely than not that we will be required to sell investments before recovery of their amortized costs. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the straight-line method and included in interest income. Interest income is recognized when earned. Realized gains and losses on investments in securities are included in other income (expense) within the consolidated statements of comprehensive income (loss). The realized gains and losses on these sales were minimal for the years ended December 31, 2013 and 2012. The following table sets forth the composition of securities available-for-sale as of December 31, 2013 and 2012 (in thousands): 35 As of December 31, 2013 Corporate debt securities As of December 31, 2012 Corporate debt securities Maturity in Years Amortized Cost Unrealized Fair Value 3 or less $ 7,675 $ — $ (2) $ 7,673 Gains Losses Maturity in Years Amortized Cost Unrealized Fair Value 3 or less $ 7,662 $ 17 $ — $ 7,679 Gains Losses Allowance for Doubtful Accounts and Billing Adjustments Accounts receivable consist principally of trade receivables from customers and are generally unsecured and due within 30 days. Expected credit losses related to trade accounts receivable are recorded as an allowance for doubtful accounts within accounts receivable, net in the consolidated balance sheets. We review reserves on a quarterly basis and make adjustments based on historical experience and known collectability issues and disputes. A provision for billing adjustments is charged against DIS revenues and a provision for doubtful accounts is charged to general and administrative expenses. When internal collection efforts on accounts have been exhausted, the accounts are written off by reducing the allowance for doubtful accounts. The following table summarizes our allowance for doubtful accounts and billing adjustments as of and for the years ended December 31, 2013, 2012 and 2011 (in thousands): Balance at December 31, 2010 Provision Write-offs and recoveries, net Balance at December 31, 2011 Provision Write-offs and recoveries, net Balance at December 31, 2012 Provision (release) Write-offs and recoveries, net Balance at December 31, 2013 Allowance for Doubtful Accounts (1) Reserve for Billing Adjustments (2) $ $ 1,187 237 (676) 748 224 (459) 513 (150) (93) 270 $ $ 412 868 (924) 356 232 (507) 81 29 (102) 8 (1) (2) The provision was charged against general and administrative expenses. The provision was charged against revenue. Inventory Our inventories are stated at the lower of cost (first-in, first-out) or market (net realizable value) and we review inventory balances for excess and obsolete inventory levels on a quarterly basis. Costs include material, labor and manufacturing overhead costs. We rely on historical information to support our excess and obsolete reserves and utilize our business judgment with respect to estimated future demand. Per our policy, we generally reserve 100% of the cost of inventory quantities in excess of a defined period of demand. Once inventory is reserved, we do not adjust the reserve balance until the inventory is sold or disposed. As a result of the Diagnostic Imaging restructuring initiative announced in February 2013, we recorded approximately $1.2 million of reserve for excess and obsolete inventory for the year ended December 31, 2012. 36 The following table summarizes our reserves for excess and obsolete inventory as of and for the years ended December 31, 2013, 2012 and 2011 (in thousands): Balance at December 31, 2010 Provision Write-offs and scrap Balance at December 31, 2011 Provision Write-offs and scrap Balance at December 31, 2012 Provision Write-offs and scrap Balance at December 31, 2013 Reserve for Excess and Obsolete Inventories (1) $ $ 1,891 82 (380) 1,593 1,164 (192) 2,565 210 (232) 2,543 (1) The provision was charged against Diagnostic Imaging cost of revenues. Long-Lived Assets including Finite Lived Purchased Intangible Assets Long-lived assets consist of property and equipment and finite lived intangible assets. We record property and equipment at cost, and record other intangible assets based on their fair values at the date of acquisition. We calculate depreciation on property and equipment using the straight-line method over the estimated useful life of the assets which average 6 years for machinery and equipment, 3 years for computer hardware and software and the lower of the lease term or an average of 5 years for leasehold improvements. Charges related to amortization of assets recorded under capital leases is included within depreciation expense. We calculate amortization on other intangible assets using either the accelerated or the straight-line method over the estimated useful life of the assets, based on when we expect to receive cash inflows generated by the intangible assets. Impairment losses on long-lived assets used in operations are recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. No impairment losses were recorded on long-lived assets during the years ended December 31, 2013, 2012 and 2011. Valuation of Goodwill We review goodwill for impairment on an annual basis during the fourth quarter, as well as when events or changes in circumstances indicate that the carrying value may not be recoverable. We begin the process by assessing qualitative factors in determining whether it is more likely than not that the fair value of its reporting unit is less than its carrying amount. After performing the aforementioned assessment and upon review of the results of such assessment, we may begin performing step one of the two- step impairment analysis by quantitatively comparing the fair value of the reporting unit with goodwill to the carrying value of its long-term assets. If the carrying value of the long-term assets exceeds the fair value of the reporting unit, then we must perform the second step of the impairment test, whereby the carrying value of the reporting unit’s goodwill is compared to its implied fair value. If the carrying value of the goodwill exceeds the implied fair value, an impairment loss equal to the difference would be recorded. Restricted Cash As of December 31, 2013, we hold $0.2 million of money market funds that are restricted from withdrawal as they are held as collateral for a letter of credit related to an annual workers' compensation policy. Restructuring Restructuring costs are included in income (loss) from operations within the consolidated statements of comprehensive income (loss). Losses on property and equipment are recorded consistent with our accounting policy related to long-lived assets. One- time termination benefits are recorded at the time they are communicated to the affected employees. Losses on property lease obligations are recorded when the lease is abandoned or when the contract is terminated. 37 In February 2013, we announced a plan to restructure our Diagnostic Imaging business. In addition, we announced a plan in January 2014 to exit our 47,000 square foot former headquarters facility in Poway, California. See Note 10 to the audited consolidated financial statements for further information. Shipping and Handling Fees and Costs We record all shipping and handling billings to customers as revenue earned for the goods provided. Shipping and handling costs are included in cost of revenues and totaled $0.2 million, $0.2 million and $0.1 million for the years ended December 31, 2013, 2012 and 2011, respectively. Share-Based Compensation We account for share-based awards exchanged for services in accordance with the authoritative guidance for share-based compensation. Under this guidance, share-based compensation expense is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense, net of estimated forfeitures, over the requisite service period. Warranty We generally provide a 12 month warranty on our gamma cameras. We accrue the estimated cost of this warranty at the time revenue is recorded and charge warranty expense to Diagnostic Imaging cost of revenues. Warranty reserves are established based on historical experience with failure rates and repair costs and the number of systems covered by warranty. Warranty reserves are depleted as gamma cameras are repaired. The costs consist principally of materials, personnel, overhead and transportation. We review warranty reserves quarterly and, if necessary, make adjustments. The activities related to our warranty reserve for the years ended December 31, 2013, 2012 and 2011 are as follows (in thousands): Balance at beginning of year Charges to Diagnostic Imaging cost of revenues Applied to liability Balance at end of year Research and Development Research and development costs are expensed as incurred. Advertising Costs Years Ended December 31, 2013 2012 2011 $ $ 326 149 (338) 137 $ $ 297 453 (424) 326 $ $ 378 708 (789) 297 Advertising costs are expensed as incurred. Total advertising costs for each of the years ended December 31, 2013, 2012 and 2011 were $0.3 million, $0.5 million and $0.6 million, respectively. Basic and Diluted Net Income (Loss) Per Share Basic earnings per share (EPS) is calculated by dividing net income or loss by the weighted average number of common shares and vested restricted stock units outstanding. Diluted EPS is computed by dividing net income or loss by the weighted average number of common shares and vested restricted stock units outstanding and the weighted average number of dilutive common stock equivalents, including stock options and non-vested restricted stock units under the treasury stock method. Common stock equivalents are only included in the diluted earnings per share calculation when their effect is dilutive. Shares used to compute basic net income (loss) per share include 44,522, 221,335, and 289,394 vested restricted stock units for the years ended December 31, 2013, 2012 and 2011, respectively. The following table sets forth the computation of basic and diluted net income (loss) per share for the periods indicated (in thousands, except per share amounts): 38 Net income (loss) Shares used to compute basic net loss per share Dilutive potential common shares: Stock options Restricted stock units Shares used to compute diluted net loss per share Basic net income (loss) per share Diluted net income (loss) per share Years Ended December 31, 2013 2012 $ 264 $ (4,924) $ 2011 (3,342) 18,789 19,274 19,052 359 11 19,159 — — 19,274 — — 19,052 $ $ 0.01 0.01 $ (0.26) $ $ (0.26) $ (0.18) (0.18) Antidilutive common stock equivalents are excluded from the computation of diluted earnings per share. Stock options are antidilutive when the exercise prices of the stock options are greater than the average market price of the common shares. In addition, in periods where net losses are incurred, stock options with exercise prices less than the average market price of the common shares as well as unvested restricted stock units become antidilutive as well. The number of stock options that were antidilutive due to an exercise price being greater than the average market price were 177,891, 268,662, 207,600 for the years ended December 31, 2013, 2012 and 2011, respectively. Since we incurred net losses for the years ended December 31, 2012 and 2011, an incremental 403,670 and 601,491 common share equivalents were excluded from the computation of diluted net loss per share for years ended December 31, 2012 and 2011, respectively, as their effect would be antidilutive due to the net loss positions. Other Comprehensive Income (Loss) Other comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Comprehensive loss includes unrealized gains or losses on our marketable securities. Income Taxes We account for income taxes in accordance with the related authoritative guidance, which sets forth an asset and liability approach that requires the recognition of deferred tax assets and deferred tax liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that is more likely than not expected to be realized. In making such a determination, a review of all available positive and negative evidence must be considered, including scheduled reversal of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. The authoritative guidance for income taxes defines a recognition threshold and measurement attributes for financial statement recognition and measurement of a tax provision taken or expected to be taken in a tax return. The guidance also provides direction on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under the guidance, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more- likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. We recognize interest and penalties related to uncertain tax positions as a component of the income tax provision. Acquisition On December 31, 2012, we acquired the operating assets of a nuclear and ultrasound imaging business located in the Southeastern U.S. The total purchase price was $500,000, including forgiveness of a $25,000 note receivable. Of the net purchase price, $340,000 was allocated to intangible assets and $135,000 to property, plant and equipment. The acquisition was accounted for as a business combination. Accounting Standards Updates In February 2013, the Financial Accounting Standards Board (FASB) issued guidance on disclosure requirements for items reclassified out of accumulated other comprehensive income. This new guidance requires entities to present (either on the face of the statement of operations or in the notes to the financial statements) the effects on the line items in the statement of operations for amounts reclassified out of accumulated other comprehensive income. We adopted this guidance beginning on January 1, 2013. 39 The adoption did not have an effect on our financial condition or results of operations, and only resulted in a change to financial statement presentation and disclosure.

Fair Value Measurements We categorize our assets and liabilities measured at fair value into a three-level hierarchy in accordance with the authoritative guidance for fair value measurements. Assets and liabilities presented at fair value in our consolidated balance sheets are generally categorized as follows: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Level 3: Observable inputs other than Level 1 prices, 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. Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Such assets and liabilities may have values determined using pricing models, discounted cash flow methodologies, or similar techniques, and include instruments for which the determination of fair value requires significant management judgment or estimation. As required by the authoritative guidance for fair value measurements, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels. The following table sets forth by level within the fair value hierarchy our assets that were recorded at fair value as of December 31, 2013 and 2012 (in thousands). Assets: Corporate debt securities Assets: Corporate debt securities At Fair Value as of December 31, 2013 Level 1 Level 2 Level 3 Total $ — $ 7,673 $ — $ 7,673 At Fair Value as of December 31, 2012 Level 1 Level 2 Level 3 Total $ — $ 7,679 $ — $ 7,679 Our investments in corporate debt securities are valued based on quoted market prices for identical securities. Some of the corporate debt securities we hold do not trade on a daily basis. For investments that do not trade on a daily basis, we utilize a variety of pricing sources to determine fair value and corroborate the fair value by observing market data prior and subsequent to the balance sheet date. NOTE 5. Goodwill Goodwill has been recorded within a reporting unit of our DIS segment since the acquisition of net assets from Ultrascan. As a result of our annual impairment test during the fourth quarter of 2008, we recorded a $2.5 million impairment loss due to a significant decline in our market capitalization, adjusting goodwill to its current carrying value of $0.2 million. We determined the implied fair value of our goodwill utilizing the discounted cash flow method under the income approach. Under the income 41 approach, we derived the fair value based on the present value of estimated future cash flows, which were based on historical data and assumptions pertaining to the market. In performing the 2013 goodwill impairment test, we assessed the relevant qualitative factors and concluded that it is more likely than not that the fair value of our goodwill is greater than the carrying amount. After reaching this conclusion, no further testing was performed. The qualitative factors we considered included, but were not limited to, general economic conditions, the industry outlook, our recent and forecasted financial performance and the price of our common stock. No impairment loss was recorded in 2013, 2012 or 2011. NOTE 6. Commitments and Contingencies Leases We currently lease facilities and certain automotive equipment under non-cancelable operating leases expiring from January 1, 2014 through October 31, 2017. Rent expense is recognized on a straight-line basis over the initial lease term and those renewal periods that are reasonably assured as determined at lease inception. The difference between rent expense and rent paid is recorded as deferred rent and is included in other liabilities. Rent expense was approximately $1.3 million for the years ended December 31, 2013, 2012 and 2011. As of December 31, 2013, we financed certain information technology and medical equipment and vehicles under capital leases. These obligations are secured by the specific equipment financed under each lease and will be repaid monthly over the remaining lease terms through November 30, 2017. We are committed to making future cash payments on non-cancelable operating leases and capital leases (including interest). The future minimum lease payments due under both non-cancelable operating leases and capital leases having initial or remaining lease terms in excess of one year as of December 31, 2013 are as follows (in thousands): 2014 2015 2016 2017 2018 Thereafter Total minimum lease payments Operating Leases (1) Capital Leases $ $ 1,137 $ 985 301 38 — — 2,461 $ 199 199 124 9 — — 531 (1) Operating leases amounts do not reflect the impact of the termination of the former headquarters lease in Poway, California, and subsequent entry into a lease for a separate 21,300 square foot facility in Poway, California. Both of the aforementioned events occurred subsequent to December 31, 2013. Refer to Note 10 of the consolidated financial statements for further detail. Radiopharmaceutical litigation. In April 2013, we settled a contractual dispute with our former radiopharmaceutical supplier who alleged that we, along with another radiopharmaceutical supplier, collaborated and breached our supply commitment contract. In summary, the settlement releases all parties from all claims associated with the dispute and the Company paid $385,000 which was recorded in other accrued liabilities as of December 31, 2012. The associated expense was recognized in the consolidated statement of comprehensive income (loss) for the year ended December 31, 2012. Annual Meeting Litigation. In May 2013, we were served with a complaint in Delaware Chancery Court by one of our larger shareholders, the Red Oak Fund, L.P. ("Red Oak"). In summary, the complaint alleged that the Annual Meeting of Shareholders election process (the "Election") was improperly conducted. Red Oak sought to have the results of the Election voided and to compel Digirad to conduct a new Annual Meeting process. On October 23, 2013, the Delaware Chancery Court issued a memorandum opinion in favor of the Company which upheld the Election as valid. Other matters. In the normal course of business, we have been, and will likely continue to be, subject to litigation or administrative proceedings incidental to our business, such as claims related to customer disputes, employment practices, wage and hour disputes, product liability, professional liability, commercial disputes, licensure restrictions or denials, and warranty or patent infringement. Responding to litigation or administrative proceedings, regardless of whether they have merit, can be expensive and disruptive to normal business operations. We are not able to predict the timing or outcome of these matters. 42 NOTE 7. Share-Based Compensation At December 31, 2013, we have two active stock option plans, the 2004 Stock Incentive Plan (the “2004 Plan”) and the 2011 Inducement Stock Incentive Plan (the “2011 Plan”), (collectively the “Plans”), under which stock options and restricted stock units may be granted to employees and non-employees, including members of our Board of Directors. Terms of any equity instruments granted under the Plans are approved by the Board of Directors. Stock options typically vest over the requisite service period of one to four years and have a contractual term of seven to ten years. Restricted stock units generally vest over one to three years and must be settled at the earlier of the recipients' termination date or 36 months after grant. Under the Plans, we are authorized to issue an aggregate of 2,750,000 shares of common stock. As of December 31, 2013, the Plans had 420,714 shares available for future issuance. The number of shares reserved for issuance under the 2004 Plan is subject to increase by any shares under the 1998 Stock Option/Stock Issuance Plan (the “1998 Plan”) that are forfeited, expire or are canceled up to a maximum of 1,500,000 shares. As of December 31, 2013, the number of shares provided for issuance under the 2004 Plan due to forfeited, expired and canceled shares under the 1998 Plan was 442,670 shares. Stock Options The estimated fair value of our stock options is determined using the Black-Scholes model. All stock options were granted with an exercise price equal to the fair value of the common stock on the grant date. The weighted-average grant date fair value of employee stock options granted during the years ended December 31, 2013, 2012 and 2011 was $1.06, $1.05 and $1.86 per share, respectively, which was estimated using the following weighted-average assumptions: Expected volatility Expected term (in years) Risk-free interest rate Expected dividend yield Years Ended December 31, 2013 2012 2011 56% 4.6 0.9% — 59% 6.0 1.2% — 62% 6.5 1.9% — The determination of the fair value of stock options using an option valuation model is affected by our stock price, as well as assumptions regarding a number of complex and subjective variables. The volatility assumption is based on the historical volatility of our common stock over a period of time equal to the expected term of the stock options. The expected term of our stock options is based on historical experience. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield in effect at the time of grant. At the time of grant for the fiscal year 2013 option grants, we had no plans to pay a dividend and no history of paying a dividend previously and as such an expected dividend yield of zero was utilized for purposes of determining fair value of the associated stock options. A summary of our stock option award activity as of and for the year ended December 31, 2013 is as follows (in thousands, except per share data): Options outstanding at December 31, 2012 Options exercisable at December 31, 2012 Options granted Options forfeited Options expired Options exercised Options outstanding at December 31, 2013 Options exercisable at December 31, 2013 Weighted- Average Exercise Price per Share Weighted- Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value Number of Shares 1,785 1,256 260 (157) (308) (724) 856 501 $ $ $ $ $ 2.22 2.35 2.27 1.87 5.48 1.27 1.93 1.75 4.7 3.6 $ $ 1,519 996 As share-based compensation expense under the authoritative guidance for share-based payments is based on awards ultimately expected to vest, it is reduced for estimated forfeitures. The guidance requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. At December 31, 2013, total unrecognized compensation cost related to unvested stock options was $0.3 million, which is expected to be recognized over a weighted-average period of 3.1 years. 43 Upon exercise, we issue new shares of common stock. Cash received from stock option exercises was $0.9 million during the year ended December 31, 2013, $0.3 million during the year ended December 31, 2012 and $0.1 million for the year ended December 31, 2011. We did not recognize any income tax benefits from stock option exercises as we continue to record a valuation allowance on our deferred tax assets, as more fully described in Note 8. The total intrinsic value of stock options exercised was $0.9 million during the year ended December 31, 2013, and less than $0.1 million during the years ended December 31, 2012 and 2011. Restricted Stock Units Under guidance for share-based payments, the fair value of our restricted stock awards is based on the grant date fair value of our common stock. All restricted stock units were granted with no purchase price. The weighted-average grant date fair value of the restricted stock units was $1.82 and $2.15 per share during the years ended December 31, 2012 and 2011, respectively. There were no restricted stock units granted during the year ended December 31, 2013. A summary of our restricted stock unit activity as of and for the year ended December 31, 2013 is as follows (in thousands, except per share data): Non-vested restricted stock units outstanding at December 31, 2012 Granted Forfeited Vested Non-vested restricted stock units outstanding at December 31, 2013 Weighted- Average Grant Date Fair Value Per Share Number of Shares 115 $ — $ (46) $ (69) $ — $ 1.94 — 1.89 1.98 — The following table summarizes information about restricted stock units that vested during the years ended December 31, 2013, 2012 and 2011 based on service conditions (in thousands): Fair value on vesting date of vested restricted stock units Years Ended December 31, 2013 $ 136 2012 $ 350 2011 $ 507 At December 31, 2013, there were no non-vested restricted stock units and therefore no unrecognized compensation cost related to non-vested restricted stock units. Allocation of Share-Based Compensation Expense Total share-based compensation expense related to all of our share-based units for the years ended December 31, 2013, 2012 and 2011 was allocated as follows (in thousands): Cost of revenues: DIS Diagnostic Imaging Research and development Marketing and sales General and administrative Share-based compensation expense Years Ended December 31, 2013 2012 2011 $ $ 6 49 9 52 224 340 $ $ 7 82 78 127 336 630 $ $ 13 99 84 110 494 800 44 NOTE 8. Income Taxes Significant components of the provision (benefit) for income taxes are as follows (in thousands): Current provision (benefit): Federal State Total current provision (benefit) Deferred provision: Federal State Total deferred provision Total income tax provision (benefit) Years Ended December 31, 2013 2012 2011 $ $ (49) 4 (45) — — — (45) $ $ (128) 51 (77) — — — (77) $ $ 10 72 82 — — — 82 Differences between the provision (benefit) for income taxes and income taxes at the statutory federal income tax rate are as follows: Income tax expense (benefit) at statutory federal rate State income tax expense (benefit), net of federal benefit Permanent differences and other Research and development credits, current year Research and development credits, prior year Change in effective state tax rates Expiration of net operating loss carryovers Stock compensation expense Reserve for uncertain tax positions and other reserves Change in valuation allowance Provision (benefit) for income taxes Years Ended December 31, 2013 35.0 % 7.2 % 14.8 % (58.1)% (39.1)% (25.6)% 8.2 % 53.7 % 5.4 % (22.2)% (20.7)% 2012 (35.0)% (2.9)% 1.4 % (2.6)% — % 2.4 % 36.6 % — % (2.4)% 1.0 % (1.5)% 2011 (35.0)% (2.7)% 0.7 % (2.7)% — % 10.3 % 9.4 % (0.9)% 3.1 % 20.3 % 2.5 % On January 3, 2013, the American Taxpayer Relief Act of 2012 was signed into law reinstating the federal research and development credit for the 2012 and 2013 years. Accordingly, we recorded the benefit related to the 2012 federal research and development credit of approximately $0.1 million in 2013. As of December 31, 2013, we had federal and state income tax net operating loss carry forwards of $95.5 million and $30.8 million, respectively. No federal loss carry forwards expired in 2013. Federal loss carry forwards will begin to expire in 2018, unless utilized before then. State loss carry forwards of approximately $0.1 million expired in 2013, and approximately $0.1 million is set to expire in 2014 unless utilized before then. We also have federal and California research and other credit carry forwards of approximately $1.8 million and $2.1 million, as of December 31, 2013, respectively. No federal credits expired in 2013. The remaining federal credits will begin to expire in 2018. The California research credits have no expiration. Pursuant to Internal Revenue Code Sections 382 and 383, use of our net operating loss and credit carry forwards may be limited because of a cumulative change in ownership greater than 50% which may have occurred or which may occur in the future. A valuation allowance has been recognized to offset the deferred tax assets, as realization of such assets has not met the “more likely than not” threshold required under the authoritative guidance of accounting for income taxes. 45 Our net deferred tax assets consisted of the following (in thousands): Deferred tax assets: Net operating loss carry forwards Research and development and other credits Reserves Intangibles Other, net Total deferred tax assets Deferred tax liabilities—depreciation Valuation allowance for deferred tax assets Net deferred tax assets As of December 31, 2013 2012 $ $ 34,727 1,928 1,273 2,425 830 41,183 (300) (40,883) $ — $ 34,588 1,836 1,531 1,908 1,509 41,372 (441) (40,931) — The following table summarizes the activity related to our unrecognized tax benefits (in thousands): Balance at beginning of year Increases related to prior year tax positions Increases related to current year tax positions Expiration of the statute of limitations for the assessment of taxes Change in valuation allowances Balance at end of year December 31, 2013 $ 1,539 5 64 (55) — $ 1,553 2012 $ 1,621 25 81 (252) 64 $ 1,539 2011 $ 1,617 30 42 (48) (20) $ 1,621 Included in the unrecognized tax benefits of $1.6 million at December 31, 2013 was $1.3 million of tax benefits that, if recognized, would reduce our annual effective tax rate, subject to the valuation allowance. We do not expect our unrecognized tax benefits to change significantly over the next 12 months. We file income tax returns in the U.S. and in various state jurisdictions with varying statutes of limitations. We are no longer subject to income tax examination by tax authorities for years prior to 2008; however, our net operating loss carryforward and research credit carryforwards arising prior to that year are subject to adjustment. Our policy is to recognize interest expense and penalties related to income tax matters as a component of income tax benefit (expense). There were no accrued interest and penalties as of December 31, 2013 and 2012 and no interest and penalties were recognized during the years ended December 31, 2013, 2012 and 2011. NOTE 9. Employee Retirement Plan We have a 401(k) retirement plan under which employees may contribute up to 100% of their annual salary, within IRS limits. The Company contributions to the retirement plan totaled $0.2 million for each of the years ended December 31, 2013, 2012 and 2011. NOTE 10. Restructuring Charges Diagnostic Imaging restructuring initiative On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly reduce costs and focus on maximizing cash flow from our DIS services business (the "Diagnostic Imaging restructuring initiative"). The Diagnostic Imaging restructuring initiative includes a reduction in force. In addition, as part of the Diagnostic Imaging restructuring initiative, we entered into an agreement in September 2013 with a third party to outsource the majority of the manufacturing associated with our cameras. As a result of this Diagnostic Imaging restructuring initiative, we estimate that we will incur in total approximately $1.7 million to $1.8 million in restructuring charges, the vast majority of which were incurred during fiscal year 2013. Included in this estimated range is approximately $1.6 million of employee related costs, while the remaining costs include contract termination costs and other related costs. Substantially all of the restructuring efforts associated with this initiative have been completed as of December 31, 2013. Through December 31, 2013, we have expensed approximately $1.7 million of charges associated with the Diagnostic Imaging restructuring initiative, including approximately $1.5 million of employee related costs. 46 Restructuring liabilities and associated charges are measured at fair value as incurred. Restructuring charges do not include charges associated with excess inventory, any excess capacity, or personnel wages and benefits before personnel leave the Company. The following table includes information regarding our current Diagnostic Imaging restructuring initiative: (in thousands) Total Diagnostic Imaging restructuring initiative $ Accrued at December 31, 2012 Accrued Costs 1,728 — $ Cash Payments and Other Reductions Accrued at December 31, 2013 $ 1,239 $ 489 All accrued Diagnostic Imaging restructuring charges at December 31, 2013 are included in the accrued compensation line item in the audited consolidated balance sheets. All the Diagnostic Imaging restructuring charges for the year ended December 31, 2013 are included in the Diagnostic Imaging segment. Facilities restructuring initiative On January 27, 2014, we announced a plan to exit our 47,000 square foot former headquarters facility in Poway, California (the "Facilities restructuring initiative"). This action was undertaken as the facility has excess space and capacity given our current operating plan. We entered into a termination agreement to end the lease on the facility as of April 30, 2014. The original term of the lease would have continued through February 29, 2016. Concurrently with the termination of the lease for the 47,000 square foot Poway, California facility, we entered into a new lease agreement on January 23, 2014 for a separate 21,300 square foot facility in Poway, California to house our Diagnostic Imaging operations. As a result of the facilities restructuring initiative, we estimate that we will incur in total approximately $0.6 million to $0.8 million in restructuring charges, which we anticipate to be incurred in the first half of fiscal year 2014. The estimated charges are comprised of lease termination, moving and other related costs. No charges were incurred as of December 31, 2013 related to this initiative. NOTE 11. Surgical Imaging Asset Sale and License Agreement On July 31, 2013, we entered into an asset purchase agreement with Novadaq Technologies Inc. (“Novadaq”). Under the terms of the asset purchase agreement, we sold Novadaq all of our assets specifically related to an uncommercialized surgical imaging system previously in development. We also licensed certain existing Company technology to Novadaq for their use in the peri- operative field. In exchange, we received upfront consideration of $2.0 million, and could receive up to $1.0 million in deferred contingent payments based on the achievement of specific regulatory and commercial milestones. In addition a royalty on sales, if any, will be paid for a period of five years from the date of the first commercial sale of the related surgical imaging system. We identified the deliverables at the inception of the agreements and determined that the tangible assets, consisting of inventory parts, and intangible assets, consisting of the technology license and various patents and know-how, individually represent separate units of accounting because each deliverable has standalone value. The best estimated selling prices for these units of accounting were determined using the income method for the intangible assets, and a cost plus a reasonable margin basis for the tangible assets. The arrangement consideration was allocated to the deliverables based on the relative selling price method. The amount of allocable arrangement consideration is limited to the amount that is not contingent upon meeting other specified performance conditions (the non-contingent amount); therefore, the amount allocated to the deliverables was limited to the upfront cash received of $2.0 million. Since performance and delivery occurred on both deliverables during the year ended December 31, 2013, a gain of $1.6 million representing the $2.0 million of upfront consideration less legal, consulting and other transaction fees as well as the cost basis of the inventory was recorded during the year ended December 31, 2013. We expect to recognize the regulatory and commercial milestone payments as a gain if and when the milestones are achieved. We expect to recognize the sales royalty payments as a gain if and when the royalties are earned. NOTE 12. Stock Repurchase Program On February 27, 2013, our board of directors modified our stock buyback program originally adopted in February 2009 to increase repurchases to an aggregate of $7.0 million, and subsequently, on March 13, 2013, increased the stock buyback program again for repurchases of up to an aggregate of $12.0 million. During the years ended December 31, 2013, 2012 and 2011, we repurchased 1,514,843, 490,816 and 9,607 shares of our common stock, respectively, under the stock buyback program. As of December 31, 2013, an aggregate of $6.3 million remains authorized for stock buyback under the program. 47 NOTE 13. Preferred Stock Rights On May 23, 2013, the Company's Board of Directors adopted a tax benefit preservation plan in the form of a Section 382 Rights Agreement (the “382 Agreement”). The 382 Agreement is intended to diminish the risk that our ability to use our net operating loss carryforwards to reduce future federal income tax obligations may become substantially limited due to an “ownership change,” as defined in Section 382 of the Internal Revenue Code. The Board authorized and declared a dividend distribution of one right for each outstanding share of common stock, par value $0.0001 per share, of the Company to stockholders of record as of the close of business on June 4, 2013. Each right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series B Participating Preferred Stock, par value $0.0001 per share, of the Company at an exercise price of $20.00 per one one-thousandth of a Preferred Share, subject to adjustment. The rights will become exercisable following (i) the 10th business day (or such later date as may be determined by the Board of Directors) after the public announcement that an acquiring person has acquired beneficial ownership of 4.99% or more of the common shares of the Company or (ii) the 10th business day (or such later date as may be determined by the Board of Directors) after a person or group announces a tender or exchange offer that would result in ownership by a person or group of 4.99% or more of the common shares of the Company. In addition, upon the occurrence of certain events, the exercise price of the rights would be adjusted and holders of the rights (other than rights owned by an acquiring person or group) would be entitled to purchase common stock at approximately half of market value. Given the potential adjustment of the exercise price of the rights, the rights could cause substantial dilution to a person or group that acquires 4.99% or more of the Company's common stock on terms not approved by the Company's Board of Directors. No rights were exercisable at December 31, 2013. There is no impact to the Company's financial results as a result of the adoption of the rights plan for the year ended December 31, 2013. NOTE 14. Segments Our reporting segments have been determined based on the nature of the products and/or services offered to customers or the nature of their function in the organization. We evaluate performance based on the operating income (loss) contributed by each segment. Summarized annual data for segments are as follows (in thousands): 48 Gross profit by segment: DIS Diagnostic Imaging Consolidated gross profit Income (loss) from operations by segment: DIS Diagnostic Imaging (1) Consolidated income (loss) from operations Depreciation and amortization of tangible and intangible assets by segment: DIS Diagnostic Imaging Consolidated depreciation and amortization Identifiable assets by segment: DIS Diagnostic Imaging Consolidated assets Years ended December 31, 2013 2012 2011 9,343 $ 4,773 8,771 4,321 14,116 $ 13,092 $ $ 8,122 6,636 14,758 30 $ (48) $ 141 171 (5,050) $ (5,098) $ (535) (2,975) (3,510) 1,436 477 1,913 $ $ 1,814 317 2,131 $ $ 2,765 331 3,096 As of December 31, 2013 2012 11,874 $ 9,105 29,577 35,804 41,451 $ 44,909 $ $ $ $ $ $ $ $ (1) Included in the Diagnostic Imaging income (loss) from operations for the year ended December 31, 2013, are approximately $1.7 million of charges associated with our Diagnostic Imaging restructuring initiative (See Note 10), as well as a gain of approximately $1.6 million associated with the sale of assets and licensing agreement from an uncommercialized surgical imaging system previously in development (See Note 11). NOTE 15. Quarterly Financial Information (Unaudited) The following financial information reflects all normal recurring adjustments, which are, in the opinion of management, necessary for a fair statement of the results of the interim periods. Summarized quarterly data for fiscal 2013 and 2012 are as follows (in thousands, except per share data): 49 Fiscal 2013 Revenues Gross profit Income (loss) from operations (1) Net income (loss) Net income (loss) per common share—basic (2) Net income (loss) per common share—diluted (2) Fiscal 2012 Revenues Gross profit Loss from operations Net loss Net loss per common share—basic and diluted (2) 1st Quarter 2nd Quarter 3rd Quarter 4th Quarter 11,546 $ 12,890 $ 12,413 2,817 $ (2,409) $ (2,419) $ (0.13) $ (0.13) $ 3,793 $ (632) $ (616) $ (0.03) $ (0.03) $ 3,818 2,432 2,512 0.14 0.14 $ $ $ $ $ $ 12,527 3,688 780 787 0.04 0.04 12,969 $ 12,710 $ 11,817 $ 13,017 3,672 $ (1,282) $ (1,268) $ (0.07) $ 3,681 $ (906) $ (891) $ (0.05) $ 3,129 $ (1,067) $ (906) $ (0.05) $ 2,610 (1,843) (1,859) (0.10) $ $ $ $ $ $ $ $ $ $ $ (1) Included in the income (loss) from operations for the first, second, third, and fourth quarter of 2013, are approximately $1.0 million, $0.6 million, $0.1 million, and less than $0.1 million of charges, respectively, associated with our Diagnostic Imaging restructuring initiative (See Note 10), as well as a gain of approximately $1.6 million in the third quarter of 2013 associated with the sale of assets and licensing agreement from an uncommercialized surgical imaging system previously in development (See Note 11). (2) Earnings per share are computed independently for each of the quarters presented. Therefore, the sum of the quarterly net earnings per share will not necessarily equal the total for the year. NOTE 16. Subsequent Events Telerhythmics Acquisition On March 13, 2014, we entered into a membership interest purchase agreement (the “Purchase Agreement”) to acquire 100% of the membership interest of Telerhythmics, LLC ("Telerhythmics"), a provider of 24 hour cardiac monitoring services. Under the terms of the Purchase Agreement, we paid to the sellers of the membership interest (the "Sellers") an aggregate of approximately $3.47 million in cash up front and assumed approximately $131,000 in debt. In addition, there is an earn-out opportunity of up to $501,000 over approximately three years based on the Telerhythmics business meeting certain earnings before interest, taxes, depreciation and amortization (“EBITDA”) milestones. The Sellers will receive fifty percent of the EBITDA generated by the Telerhythmics business in excess of the EBITDA milestone amounts, which are $415,000 for the period from the closing date through December 31, 2014, $825,000 for the period from January 1, 2015 through December 31, 2015, and $825,000 for the period from January 1, 2016 through December 31, 2016. The Purchase Agreement is also subject to a post- closing purchase price adjustment based on the final working capital balance, as defined in the Purchase Agreement. We expect to account for the transaction as a business combination and are in the process of determining the allocation of the purchase price to acquired assets and assumed liabilities, as well as preparing pro forma financial information. Facilities Restructuring On January 22, 2014, we entered into a termination agreement to end the lease on the 47,000 square foot former headquarter facility in Poway, California as of April 30, 2014. The original term of the lease would have continued through February 29, 2016. Under the termination agreement, we will pay a termination fee of $473,050. Concurrently with the termination of the lease for the 47,000 square foot Poway, California facility we entered into a new lease agreement on January 23, 2014 for a separate 21,300 square foot facility in Poway, California to house our Diagnostic Imaging operations. The new lease agreement is for the term from March 1, 2014 through February 28, 2021. Dividend On February 3, 2014, the Company announced a dividend of $0.05 payable to shareholders of record as of February 14, 2014. The dividend was paid on February 24, 2014. 50 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURES None. ITEM 9A. CONTROLS AND PROCEDURES (a) Evaluation of Disclosure Controls and Procedures We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities and Exchange Commission Act of 1934 reports is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. As required by Securities and Exchange Commission Rule 13a-15(e) and 15d-15(e), we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level. There has been no change in our internal controls over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting. (b) Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. We conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (1992 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control—Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2013. This annual report does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Our report was not subject to attestation by our independent registered public accounting firm pursuant to the rules of the Securities and Exchange Commission that permit us to provide only a management’s report in this report.
