Annual Report 2014

Plain-text annual report

 2014 ANNUAL REPORT “Page Intentionally Left Blank” Dear Fellow Shareholders, I am very excited to be writing to you at the conclusion of a very successful year at Digirad; 2014 has proven to be the most profitable year in Digirad’s history! Not only am I excited about what we achieved in this past year, but more importantly, I am excited about what our future brings. As you may recall, we initiated an aggressive restructuring plan in February 2013 for the purpose of creating and returning shareholder value. Our plan in 2013 included such changes as right sizing our manufacturing efforts and stripping excess costs out of our business, as well as focusing our major market efforts on the Diagnostic Services side of our business. Also, financially, we focused on generating cash from our businesses, for which we began a quarterly cash dividend in November 2013 to return some of that cash to our shareholders, a program we have kept going strong every quarter since then. The result of our actions set Digirad on a pathway to profitability and future successes. In 2014, we further streamlined our business and focused on future growth efforts. To name a few accomplishments, we completed the outsourcing of the majority of our manufacturing processes as well as the remaining tasks from our February 2013 restructuring plan, we cut our facility footprint in California by half, and we acquired a very complimentary business with our Telerhythmics cardiac event monitoring business acquisition in March 2014. As I have stated over the last year and will continue to state, we are not done yet. As we look at our business and market moving forward, we are very excited about our prospects and potential for growth. With the Affordable Care Act and all the efficiencies Congress appears focused on as part of the overall healthcare environment, I believe more business will move toward our highly efficient business model. Of course, our main priorities are running our underlying businesses in a sustainable manner to generate cash and profit, and continued payment of our quarterly cash dividend. However, looking to the future, we have a three tier growth strategy at Digirad, one I am sharing with our shareholders often: 1. Acquisitions. Our goal is to acquire companies that fit within our business model of providing diagnostic services on an as needed, when needed and where needed basis in a very financially disciplined manner. 2. New Services. Adding new services that we can provide from our extensive service distribution channels. 3. Organic Growth. Within our existing core business service lines and products. Even as I write this letter, we continue to move forward with our three tier growth plan, having just acquired MD Office Solutions in March 2015, a very well-run diagnostic imaging services business based in Northern California. We are not going to stop; the entire Executive Team and I are fighting to grow the business and to return value to you, and we appreciate all your support. Finally, I would like to thank all our employees; both employees that have been with Digirad for years and employees that may have just joined from one of our recent acquisitions. We value YOU at Digirad – everything that we are accomplishing is from your hard work and dedication, and the Executive Team truly appreciates your hard work. Sincerely, Matthew G. Molchan President and Chief Executive Officer Table Of Contents UNITED STATES SECURITIES AND EXCHANGE COMMISSION WASHINGTON, DC 20549 Form 10-K (Mark One) ANNUAL REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 For the fiscal year ended December 31, 2014 or TRANSITION REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 For the transition period from to Commission file number: 000-50789 Digirad Corporation (Exact Name of Registrant as Specified in its Charter) Delaware (State or Other Jurisdiction of Incorporation or Organization) 1048 Industrial Court, Suwanee, GA (Address of Principal Executive Offices) 33-0145723 (I.R.S.

Corporate Information Digirad Corporation was incorporated in Delaware in 1997 as a subchapter C corporation. Unless the context requires otherwise, in this report the terms “we,” “us,” and “our” refer to Digirad® Corporation and our wholly-owned subsidiaries, Digirad Imaging Solutions®, Inc. and Telerhythmics®, LLC. ITEM 1. BUSINESS Overview Digirad delivers convenient, effective, and efficient diagnostic solutions on an as needed, when needed, and where needed basis. We are one of the largest national providers of in-office nuclear cardiology and ultrasound imaging services, and also provide cardiac event monitoring services. These services are provided to physician practices, hospitals, and imaging centers through our Diagnostic Services 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 business 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 portable imaging system is a large field-of-view general purpose imager featuring a sleek ergonomic 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. 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. 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. Through Diagnostic Services, we offer a convenient and economically efficient imaging services program as an alternative to purchasing a gamma camera or ultrasound equipment, or as an alternative to 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. Diagnostic Services segment's services are also used by large and small hospitals, multi-practice physician groups, and imaging centers. The flexibility of our products and our Diagnostic Services segment's services allow 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. Diagnostic Services segment's services are primarily provided to cardiologists, internal medicine physicians, and family practice doctors who enter into contracts for a set number of service days ranging from once per month to five times per week. We experience some seasonality in our Diagnostic Services business related to vacations, holidays, and inclement weather. Most of the Diagnostic Services business focuses on cardiac care. Many of the physicians who use Diagnostic Services segment's services are reliant on reimbursements from Medicare, Medicaid, and third-party insurers where, in the past, there has been downward price pressure and uncertainty of 1 Table Of Contents reimbursement rates 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 in the past, and will likely have some impact on our business in the future. Future changes and impacts may require modifications to our current business model in order for our physician customers and us to maintain a viable economic model. Through Diagnostic Services, we also offer an outsourced cardiac event monitoring service through our Telerhythmics business. Providing these services offers flexibility and convenience to our customers who do not have to incur the costs of staffing, equipment, and logistics to monitor patients as part of their standard of care. Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. As such, our cardiac event monitoring services are subject to reimbursements from Medicare, Medicaid, and third-party insurers which are subject to change on a periodic basis. Our cardiac event monitoring services are mainly provided to physician practices and hospitals. Our Diagnostic Imaging segment's revenue is derived primarily from selling solid-state gamma cameras and post-warranty camera support contracts. We sell our imaging systems to physician offices, hospitals, and imaging centers primarily in the United States, although we have sold some 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 Diagnostic Services business. This restructuring effort also included a reduction in force. Our restructuring efforts were complete as of December 31, 2014. 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 11 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. Though the utilization rates of competing modalities such as CT, PET, and MRI, and diagnostic procedures such as CT angiography are high, SPECT procedures performed with gamma cameras are expected to continue to be used for a substantial number of cardiac-specific imaging procedures. 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. 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, which are specially formulated to concentrate temporarily in the specific part of the body to be studied. The radiation signals emitted by the radiopharmaceutical 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 as well as a number of internists and other physicians either purchase our nuclear cameras or subscribe to our Diagnostic Services services for in-office cardiac imaging for these advantages. Ultrasound Imaging Ultrasound imaging 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. 2 Table Of Contents 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. Cardiac Event Monitoring Cardiac event monitoring is a form of diagnostic test that allows physicians to see the electrocardiogram (ECG) of a patient’s heart rhythm over a period of time or related to a specific event. The test includes a small monitor that is worn on the patient’s waist and is connected to lead wires affixed to the patient’s chest. The purpose of this test is to capture infrequent heart conditions that may only be experienced outside a physician’s office, as well as to observe the state of the heart in various resting and active situations. Clinical Applications for Cardiac Event Monitoring Cardiac event monitoring is a widely utilized cardiac test that provides clinical benefit in situations where the patient’s symptoms occur erratically or infrequently. Often symptoms can occur infrequently, but still be related to life-threatening cardiac conditions that need to be corrected. The use of a cardiac event monitor allows these symptoms to be captured and diagnosed, and ultimately corrected via prescription medications or use of invasive procedures, if required. Our Imaging Services Diagnostic Services 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 (often a certified or 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 Diagnostic Services 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 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 typically runs for one year, as well as a variable cost associated with the associated volume of patients utilizing our services and radiopharmaceuticals. 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 Cardiac Event Monitoring Services Diagnostic Services also offers remote cardiac event monitoring services. These services include provision of a monitor, remote monitoring by registered nurses, and 24 hours a day, 7 days a week monitoring support for our patients and physician customers. We offer modalities of: mobile cardiac telemetry (MCT), mobile cardiac event monitoring (both in wireless and analog versions), holter monitoring, and pacemaker analysis. Our monitoring service operates out of a centralized monitoring center located near Memphis, Tennessee. From this location, the majority of monitoring equipment is shipped directly to patient homes once they are enrolled in our service. Patients hook up the equipment with easy to follow instructions, as well as assistance from our monitoring center. Once they are hooked up to the monitoring device, patients are monitored for a period of time ranging from 7 to 30 days. At the conclusion of the monitoring period, the equipment is packaged up and sent back to our monitoring center, after which the equipment is redeployed to the next patient. 3 Table Of Contents We provide our services under contracts with our customers that typically allow for direct billing to Medicare, Medicaid, or third-party private payors once the monitoring cycle is complete. Typically, our contracts can be canceled at any time, and are generally present to create understanding on billing responsibilities. 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. We are a market leader in the mobile solid-state nuclear camera segment. 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, chronic obstructive pulmonary disease (COPD), or claustrophobic patients that typically could not be imaged lying down on competitive systems. We offer fixed dual-head and triple-head cardiac camera models for dedicated use within a facility and portable configurations that make it possible to move the system to provide service to multiple rooms or sites. 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 services to our customers at the point of need. Imaging Services and Products • Broad Portfolio of Cardiovascular Imaging Services. One of our main competitive advantages is our ability to offer nuclear cardiology imaging, echocardiography imaging, and vascular imaging services. Our ability to offer multiple services strengthens our competitive position at each customer location. The depth of imaging 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 Diagnostic Services, we offer both nuclear and ultrasound services 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 model 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 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. 4 Table Of Contents • 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 Diagnostic Services 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 on our imaging cameras 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. Cardiac Event Monitoring Services • Consistent and Relevant Portfolio of Services. In addition to our imaging services, many of our customers require cardiac event monitoring services, and prefer to deal with one service provider to ensure continuity of services and ease of communication. With this new service offering since our acquisition of Telerhythmics, we strengthen our position at each customer location. • Excellent Customer Service. We operate our cardiac event monitoring services utilizing equipment that meets our customers’ needs. We do not manufacture any cardiac event monitors ourselves, and are therefore not tethered to any particular device or product unlike many of our competitors; we utilize the best technology for our customers’ application and to meet their needs. • Utilization of Highly Trained Staff. We staff our monitoring center only with registered nurses, which provides a much higher level of experience, analysis, and assistance to our customers. Many of our competitors staff their monitoring centers with lesser trained technicians that are not registered nurses, which can lead to poor customer service and poor clinical outcomes. Business Strategy Our goals are to achieve and maintain consistent profitability and operating cash flow generation, and grow our business over time via the following: Diagnostic Services. 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 Diagnostic Services business, with efforts to help it grow over time. Since 2013, we believe the market has shown signs of stabilization in relation to healthcare reform and reimbursement uncertainties and we believe the market has been, and will be, more stable going forward. In addition, we believe that market will be pushed more toward a “market efficient model”, similar to the model provided by our Diagnostic Services business. Our model takes the inefficiencies often associated with medical practices owning their own capital equipment and providing their own staffing and moves it into a streamlined and efficient operation, exactly where we believe healthcare of the future is moving to. Further, we believe that we have the opportunity to focus our sales approach within our current operating markets 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. Finally, we also believe there are a variety of smaller mobile imaging and health care services businesses within the United States, both inside and outside our current operating markets, 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 Diagnostic Services 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 5 Table Of Contents 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 have focused our 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 an enhanced 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 room and the surgical suite. Further, as a result of our Diagnostic Imaging restructuring announced in February 2013, we have, and believe we can continue to maintain, 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 our outsourced 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 11 to the audited consolidated financial statements for further information regarding our Diagnostic Imaging restructuring. Business Segments Our business is organized into two reportable segments: Diagnostic Services and Diagnostic Imaging. See Note 15 to the audited consolidated financial statements for certain segment financial data relating to our business. For the year ended December 31, 2014, we had one customer, Emory Healthcare, that exceeded 10% of our consolidated revenues. For 2014, Emory Healthcare represented 10.9% of our consolidated revenues and 14.3% of our Diagnostic Services revenues. Prior to 2014, no single customer exceeded 10% of our consolidated revenues. We believe we have good relations with Emory Healthcare, however, if we were to lose Emory Healthcare as a customer, it would likely have a material adverse affect on our operations. 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, with the transition essentially complete at the end of 2014. We believe that our outsourcing efforts resulted in increased efficiencies, flexibility to meet customer demand, and 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 received certification authorizing CE Marking of our Cardius® XPO, Cardius® X-ACT, and ergoTM 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 an 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 molecular breast imaging. Raw Materials We, as well our outsource manufacturers, 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. These materials are primarily purchased from external suppliers, some of which are single-source suppliers. Materials are purchased 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 diagnostic services and nuclear imaging 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 diagnostic 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 6 Table Of Contents uncertainty in overall healthcare and changes in healthcare, such as the Affordable Care Act. These concepts, along with, until recently, an overall depressed economy, have 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 Diagnostic Services 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 Diagnostic Services service contract. In addition, we compete against imaging centers that install fixed nuclear 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 providing cardiac event monitoring services, we compete against many smaller local and regional service providers, as well as against a few larger, well established medical device companies that provide devices and also provide a service model similar to ours. We believe our advantage in providing our services is the ability to utilize any cardiac event device on the market, and not being constrained by using any particular device. However, our larger competitors have larger sales forces and deeper financial resources that may allow them to have higher cost efficiencies. Further, larger competitors may develop devices that may make our owned devices obsolete, causing us to suffer financial losses as we attempt to change our technology and service model to adapt. 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, which sells our nuclear gamma cameras and support, and our Diagnostic Services sales, which sells our mobile nuclear and ultrasound imaging, as well as our cardiac event monitoring services. Relative to nuclear imaging, these 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. Diagnostic Services sales teams are aligned across geographic areas we have established in order to better serve local market needs. Our Diagnostic Services 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 Diagnostic Services market penetration by focusing on those hospitals and practices that are already within an existing Diagnostic Services operational area in order to increase the density of our current operations and increase the efficiency of our overall cost structure, as well as cross selling our cardiac event monitoring services to our current nuclear and ultrasound imaging customers. 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 we believe, over time, these relationships can be developed to increase presence and sales to countries 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 Diagnostic 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 7 Table Of Contents 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, and 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 were zero, $1.0 million, and $3.7 million in 2014, 2013, and 2012, 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 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 physician regularly practices 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 regulations. 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 Diagnostic Services business. 8 Table Of Contents • 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 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, 2014, we hold trademark registrations in the United States for the following marks: 2020tc IMAGER®, Digirad®, DigiServ®, Cardius®, SPECTour®, SPECTpak Plus®, Solidium®, DigiTech®, and Telerhythmics®. We have obtained 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 and services are 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” 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, and could change further over time. 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 9 Table Of Contents typically seek reimbursement by Medicare for outpatient services under the Medicare Hospital Outpatient Prospective Payment System. Employees As of December 31, 2014, we had a total of 297 full time employees, of which 200 were employed in clinical related positions, 38 in operational roles, 40 in general and administrative functions, and 19 in marketing and sales. We also utilize varying amounts of temporary workers 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 Diagnostic Services 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 due to reductions in Medicare and Medicare reimbursement rates. The success of our business is largely dependent upon our medical professional customers' ability to provide diagnostic care to their patients in an economically sustainable manner, either through the purchase of our imaging systems or using our diagnostic services, or both. Our customers are directly impacted by changes (decreases and increases) in governmental and private payor reimbursements for diagnostic services. We are directly and indirectly impacted by changes in reimbursements. For our businesses where we are indirectly affected by reimbursement changes, we make every effort to act as business partners with our physician customers. For example, in 2010, we proactively adjusted our diagnostic imaging services rates down due to the dramatic reimbursement declines that our customers experienced 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 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. A smaller portion of our Diagnostic Services business segment operates in the hospital market. Reductions in reimbursements could significantly impact the viability of in-office imaging performed by independent physicians, as well as the viability of our cardiac event monitoring services business. The historical decline in reimbursements in diagnostic imaging has resulted in cancellations of imaging days in our Diagnostic Services business and the delay of purchase and service decisions by our existing and prospective customers in our Diagnostic Imaging business. Declines in Medicare and Medicaid reimbursement for our relevant diagnostic services modalities are possible due to many factors, including but not limited to, the potential 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 services. The application of the SGR has been delayed by Congress for many years, with annual delays of implementation each year. Adoption of SGR could result in Medicare cost reimbursements being reduced over 20% and would impact our business dramatically. 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. 10 Table Of Contents Unexpected changes in our relationship with Emory Healthcare could result in a significant reduction in our sales and profits. Emory Healthcare has contributed a high percentage of our our consolidated revenue. For 2014, Emory Healthcare (Emory) represented 10.9% of our consolidated revenues and 14.3% of our Diagnostic Services revenues. Prior to 2014, Emory did not exceed 10% of our consolidated revenues, however, they were still a significant customer. We expect that Emory will continue to be one of our most important customers, and it is possible our relationship could expand or contract in the future. Though we do not anticipate any near term changes in our relationship and believe we do have excellent relations with Emory, our business could be materially adversely affected if Emory terminates its arrangement with us, negotiates lower prices, or otherwise alters the nature of its relationship with us. Our Diagnostic Services revenues may decline due to changes in diagnostic imaging regulations and the use of third party benefit managers by states and private payors to drive down diagnostic 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 (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 Diagnostic Services 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 Diagnostic Services imaging services. Recently, we outsourced 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. We are now reliant on our third party manufacturer, which could 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 and providing service for 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, even through an outsource manufacturer, and our after sale camera support business, relies on a limited number of third parties to 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, our ability to have gamma cameras built as well as our ability to provide support could be materially adversely affected. We have developed backup plans and have alternative procedures should we experience a disruption. However, if these plans are unsuccessful, delays in the production and support of 11 Table Of Contents our gamma cameras for an extended period of time could cause a loss of revenue and/or higher production and support costs, which could significantly harm our business and results of operations. Our Diagnostic Services 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 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 limited 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. Our business is not widely diversified. We provide our diagnostic 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. If we are unable to expand our current market share, our revenues and related financial condition could decline. In addition, our Diagnostic Services customers may switch to other service providers. Our Diagnostic Services segment, both in diagnostic imaging and cardiac event monitoring, compete against a variety of competitors, some of whom have the advantage of a lower cost structure, and in the case of diagnostic imaging, 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 Diagnostic Services business, and in the past, volatility due to the changing health care environment, the variable supply of radiopharmaceuticals, and the downturns based on the changing U.S. economy. While our physicians are typically 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. 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 12 Table Of Contents 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 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. 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 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 13 Table Of Contents 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 may not be able to achieve the anticipated synergies and benefits from business acquisitions, including our recent acquisition of Telerhythmics, LLC. Part of our ongoing business strategy is to acquire businesses that we believe can complement our current business activities, both financially and strategically. On March 13, 2014, we acquired Telerhythmics, LLC with these synergistic benefits in mind. Acquisitions include many complexities, which can include, but are not limited to, risks associated with the acquired business' past activities, loss of customers, regulatory changes that are not anticipated, difficulties in integrating personnel and human resource programs, integrating ERP systems and other infrastructures, and general under performance of the business under Digirad control versus the prior owners. There is no guarantee that our acquisitions will increase the profitability and cash flow of Digirad, and our efforts could cause unforeseen complexities and additional cash outflows, including financial losses. We may make financial investment in other businesses that may lose value. As we look for the best ways to deploy our capital and maximize our returns for our businesses and shareholders, we may make financial investments in other businesses or processes for purposes of enhancing our supply chain, creating financial returns, strategic developments, or other purposes. These investments may be speculative in nature, and there is no guarantee that we will experience a financial return and we may lose our entire principal balance if not successful. Risks Related to Our Common Stock 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 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. We have 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 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. 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. 14 Table Of Contents 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 had been leased to us on a month to month basis previously. On October 1, 2014, we entered into a long-term lease agreement for the same facility, extending our lease terms to November 30, 2021. 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 11 to the audited consolidated financial statements for further information. In addition to the aforementioned properties, Diagnostic Services leases approximately 25 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. Diagnostic Services also operates a cardiac event monitoring center which is located in an approximately 8,078 square foot facility in Collierville, Tennessee. The lease will expire on March 12, 2021. ITEM 3. LEGAL PROCEEDINGS See Note 7 to the audited consolidated financial statements for a summary of legal proceedings. ITEM 4.

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, 2014 2013 High Low High Low $ $ 3.88 3.73 4.19 4.49 $ 3.03 3.03 3.11 3.50 $ 2.53 2.68 2.84 4.85 1.80 2.16 2.32 2.50 As of February 24, 2015 there were approximately 172 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 four quarterly cash dividends of $0.05 per common share for total dividends paid of $0.20 per common share during the year ended December 31, 2014. On February 2, 2015, we announced a dividend of $0.05 per common share payable on February 23, 2015 to shareholders of record as of February 13, 2015. 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 fiscal year 2014. 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, and also provide cardiac event monitoring services. Our services are provided to physician practices, hospitals, and imaging centers through our Diagnostic Services business segment. We also sell 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 business 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: Diagnostic Services and Diagnostic Imaging. Our primary service offering through Diagnostic Services is 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 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 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. The imaging 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 related to vacations, holidays, and inclement weather. Most of the imaging services are focused on cardiac care. Many of the physicians who use Diagnostic Services segment's services are reliant on reimbursements from Medicare, Medicaid, and third-party insurers where, in the past, there has been downward price pressure and uncertainty of reimbursement rates 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 in the past, and will likely have some impact on our business in the future. Future changes and related impacts may require modifications to our current business model in order for our physician customers and us to maintain a viable economic model. With the acquisition of Telerhythmics, LLC on March 13, 2014, we broadened our suite of service offerings provided through the Diagnostic Services segment, enabling the provision of outsourced cardiac event monitoring services. Providing these services offers flexibility and convenience to our customers who do not have to incur the costs of staffing, equipment, and logistics to monitor patients as part of their standard of care. Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. As such, our cardiac event monitoring services are subject to reimbursements from Medicare, Medicaid, and third-party insurers which are subject to change on a periodic basis. Our cardiac event monitoring services are mainly provided to physician practices and hospitals. 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 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, 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 (the Diagnostic Imaging restructuring initiative). The Diagnostic Imaging restructuring initiative involved a reduction in force focused on manufacturing, 19 Table Of Contents research and development, and administrative personnel. In addition, we entered into an agreement in September 2013 with a third party to outsource the majority of the manufacturing associated with our cameras. All restructuring efforts associated with this initiative were complete as of June 30, 2014. Further, on January 27, 2014, we entered into a termination agreement to end the lease on our 47,000 square foot former headquarters facility in Poway, California (the Facilities restructuring initiative) and moved our Diagnostic Imaging operations into a separate 21,300 square foot facility. All restructuring efforts associated with the Facilities restructuring initiative were complete as of December 31, 2014. With these restructuring initiatives complete, we are primarily focusing our efforts on growing our Diagnostic Services business, which we plan to accomplish by driving revenue density with our existing customers by providing additional service offerings such as cardiac event monitoring, as well as by increasing our overall customer relationships through territory expansion and acquisition of smaller diagnostic services companies. We will also continue to evaluate acquisition opportunities related to complementary healthcare services and products to diversify and expand our current offerings. We will continue to sell and service our cameras, but at a more profitable level with our restructured, leaner 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, or have a need for cardiac event monitoring. During the year ended December 31, 2014, through Diagnostic Services we provided imaging services to 617 physicians and physician groups and cardiac event monitoring services to 313 physicians and physician groups. Our Diagnostic Services business currently operates in 27 states. As discussed earlier, in the past 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 addressed, and will continue to address, these market pressures by modifying our Diagnostic Services business model, and by assisting our physician customers in complying with new regulations and requirements. Trends and Drivers The medical device and services industry, including the market for nuclear and ultrasound imaging systems and services and cardiac event monitoring, is highly competitive. Our business continues to be affected by many factors, including healthcare reimbursement rates, competition from alternative imaging modalities such as positron emission tomography (PET) and computed tomography (CT) angiography, competition from small owner-operated mobile nuclear imaging providers as well as from larger entrenched competitors in the cardiac event monitoring market, 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, though we have seen reimbursements stabilize in the last few years. In our Diagnostic Services segment, our physician customers continue to experience uncertainty in reimbursements from CMS and third party insurance providers for the codes under which our physician customers bill for our services, though, again, we have seen reimbursements stabilize in the last few years. In addition, there has been a trend of physician customers selling their practices to hospitals or larger healthcare systems, which may 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 (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 high 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. 2014 Financial Highlights Our consolidated revenues were $55.6 million for the year ended December 31, 2014. This is an increase of $6.2 million, or 12.6%, compared to the prior year period driven by a $5.0 million, or 13.4%, increase in our Diagnostic Services revenue year 20 Table Of Contents over year. The increase in Diagnostic Services revenue is primarily due to $3.9 million of incremental cardiac event monitoring revenue resulting from the Telerhythmics acquisition, which occurred on March 13, 2014. We also experienced an increase in the number of days our physician customers utilized our imaging services, driven by the attainment of new customers, partially offset by a reduction in our average daily service fee rates. Diagnostic Imaging segment revenues for the year ended December 31, 2014 increased by $1.2 million, or 10.1%, compared to the prior year, primarily due to an increase in the volume of cameras sold. The number of cameras sold increased to 27 from 20 during the years ended December 31, 2014 and 2013, respectively. Consolidated gross profit increased $2.5 million, or 17.9%, compared to the prior year. The increase in consolidated gross profit is primarily the result of increased overall revenue volume as well as improved gross profit as a percentage of revenue in our Diagnostic Imaging business, with gross profit as a percentage of revenue remaining relatively consistent year over year in our Diagnostic Services business. Our Diagnostic Imaging business segment benefited from the release of excess inventory reserves due to the sale of previously reserved inventory, as well as reduced manufacturing and overhead costs for the year ended December 31, 2014, compared to the prior year. Our total operating expenses remained relatively consistent for the year ended December 31, 2014 compared to the prior year, with decreases in research and development and restructuring costs during the year ended December 31, 2014 offset by the non-recurrence of the $1.6 million one-time gain on the sale of technology to Novadaq which occurred during the year ended December 31, 2013. Our consolidated net income for the year ended December 31, 2014 was $2.5 million, which is an increase of $2.2 million compared to our net income of $0.3 million during the prior year. For the year ended December 31, 2014, Diagnostic Services operated 78 nuclear gamma cameras and 60 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 66% for the year ended December 31, 2014, compared to 63% 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 contractual allowances and 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, cardiac event monitoring, 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. Diagnostic Services imaging services 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. Diagnostic Services segment's 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. Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. We also receive reimbursement directly from patients through co-pays and self-pay arrangements. Billings for services reimbursed by third party payors, including Medicare, are recorded as revenue net of contractual allowances. Contractual allowances are estimated based on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. Adjustments to the estimated receipts, based on final settlement with the third party payors, are recorded upon settlement. 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 21 Table Of Contents 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 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 (VSOE) of selling price nor 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 doubtful accounts and billing adjustments. 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 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 Diagnostic Services, we record adjustments and credit memos that represent billing adjustments subsequent to the performance of service. A provision for billing adjustments is charged against Diagnostic Services revenues and a provision for doubtful accounts is charged to general and administrative expenses. Contractual Allowances Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. Accounts receivable for cardiac event monitoring are recorded at the time revenue is recognized, net of contractual allowances. Contractual allowances are estimated based on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. The ultimate collection of accounts receivable may not be known for several months after services have been provided and billed. Because of continuing changes in the health care industry and third party reimbursement, it is possible that our estimates could change, which could have a material impact on our operations and cash flows. Business Combinations Under the acquisition method of accounting, we allocate the fair value of the total consideration transferred to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants, are based on estimates and assumptions determined by management. We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. These valuations require us to make significant estimates and assumptions, especially with respect to intangible assets. In connection with certain of our acquisitions, additional contingent consideration is earned by the sellers upon completion of certain future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition date fair value of the contingent consideration by applying the income approach utilizing variable inputs such as anticipated future cash flows, risk-free adjusted discount rates, and nonperformance risk. Any change in the fair value of the contingent consideration subsequent to the acquisition date is recognized in acquisition related (gain) expense, net, a component of operating expenses, in our consolidated statements of comprehensive income (loss). This method requires significant management judgment, including the probability of achieving certain future milestones and discount rates. Future changes in our estimates could result in expenses or gains. Management typically uses the discounted cash flow method to value our acquired intangible assets. This method requires significant management judgment to forecast future operating results and establish residual growth rates and discount factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could experience impairment charges. In addition, we have estimated the economic lives of certain acquired 22 Table Of Contents assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, depreciation or amortization expenses could be accelerated or slowed. 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 5 to the audited consolidated financial statements 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 are 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, 2014, 2013, or 2012. 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, 2014, 2013, or 2012. 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 terminated. 23 Table Of Contents 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 11 to the audited consolidated financial statements for further detail. 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 $55.6 million for the year ended December 31, 2014, an increase of $6.2 million, or 12.6%, from the prior year, driven by a $5.0 million, or 13.4%, increase in our Diagnostic Services revenue year over year. The increase in Diagnostic Services revenue is primarily due to $3.9 million of incremental cardiac event monitoring revenue resulting from the Telerhythmics acquisition, which occurred on March 13, 2014. The remaining increase in Diagnostic Services revenue for the year ended December 31, 2014 compared to the prior year is due to a greater number of imaging days provided, offset partially by a decrease in the average mobile imaging rate per day. Diagnostic Imaging revenue increased $1.2 million, or 10.1%, compared to the prior year, as a result of a greater volume of camera units sold during the year ended December 31, 2014 compared to the prior year. Diagnostic Services revenue accounted for 75.8% of total revenues for the year ended December 31, 2014, compared to 75.3% for the prior year. We expect Diagnostic Services revenue to continue to represent the larger percentage of our consolidated revenue. Diagnostic Services. Our Diagnostic Services revenue was $42.2 million for the year ended December 31, 2014, an increase of $5.0 million, or 13.4%, from the prior year. The primary driver of the increase is the Telerhythmics acquisition, which occurred on March 13, 2014, and contributed $3.9 million of incremental cardiac event monitoring revenue during the year ended December 31, 2014. The remaining increase in Diagnostic Services revenue for the year ended December 31, 2014 compared to the prior year was due to a greater number of imaging days provided as well as greater ancillary revenue from short term equipment rentals, offset partially by a decrease in the average mobile imaging rate per day. Diagnostic Imaging. Our Diagnostic Imaging revenue was $13.4 million for the year ended December 31, 2014, an increase of $1.2 million, or 10.1%, compared to the prior year, primarily due to an increase in the volume of cameras sold, offset partially by attrition in the number of associated camera maintenance contracts. The number of cameras sold increased to 27 from 20 during the years ended December 31, 2014 and 2013, respectively, as a result of additional sales resources and overall improved market conditions. Further, a more favorable product mix was sold during the year ended December 31, 2014 as compared to the prior year, which led to a higher blended average selling price per camera year over year. Cost of Revenue and Gross Profit Consolidated. Consolidated gross profit was $16.6 million for the year ended December 31, 2014, an increase of $2.5 million, or 17.9%, compared to the prior year. The increase in consolidated gross profit is primarily the result of increased overall revenue volume as well as improved gross profit as a percentage of revenue in our Diagnostic Imaging business. Our Diagnostic Imaging business segment benefited from the release of excess inventory reserves due to the sale of previously reserved inventory, as well as reduced manufacturing and overhead costs for the year ended December 31, 2014, compared to the prior year. Consolidated gross profit as a percentage of revenue increased to 29.9% for the year ended December 31, 2014 from 28.6% for the prior year. Diagnostic Services. Cost of Diagnostic Services revenue consists of labor, radiopharmaceuticals, equipment depreciation, and other costs associated with the provision of services. Cost of Diagnostic Services revenue was $31.7 million for the year ended December 31, 2014, an increase of $3.9 million, or 14.0%, from the prior year. The increase in cost of Diagnostic Services revenue is primarily a result of the provision of incremental cardiac event monitoring services associated with the Telerhythmics acquisition as well as an increased amount of imaging days provided. Diagnostic Services gross profit was $10.4 million for the year ended December 31, 2014, an increase of $1.1 million, or 11.8%, as compared to the prior year primarily as a result of increased revenue year over year. Diagnostic Services gross profit as a percentage of Diagnostic Services revenue decreased to 24.8% for the year ended December 31, 2014 from 25.1% in the prior year. The decrease in gross profit as a percentage of revenue was attributable to a decrease in the average mobile imaging rate per day with the associated service costs remaining relatively consistent, as well as first year integration efforts and costs associated with the Telerhythmics acquisition, partially offset by favorable gross profit contribution from short term equipment rentals. We expect to continue to have integration costs and some inefficiencies in our cardiac event monitoring business during the first half of 2015, after which we believe costs will be reduced and efficiencies will increase. 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 $7.2 million for the year ended December 31, 2014, a decrease of $0.2 million, or 2.5%, over the prior year, primarily as a result of a net $0.6 million release of excess inventory reserves due to the sale of previously reserved inventory during the year ended December 31, 2014, as well as reduced manufacturing and overhead costs. Diagnostic Imaging gross profit was $6.2 million for the year ended December 31, 2014, an increase of $1.4 million, or 29.7%, as compared to the prior year due to a greater volume of camera sales, and the release of excess inventory reserves due to the sale of previously reserved inventory, as well as reduced manufacturing and overhead costs. Diagnostic Imaging gross profit as a percentage of Diagnostic Imaging revenue increased to 46.1% for the year ended December 31, 2014 from 39.1% for the prior year primarily due to reduced excess and obsolete inventory costs, reduced manufacturing and overhead costs, and a more favorable product mix for cameras. 26 Table Of Contents 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. There were no research and development expenses for the year ended December 31, 2014, representing a decrease of $1.0 million, or 100.0%, 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. 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 0.0% and 8.4% of Diagnostic Imaging revenue for the years ended December 31, 2014 and 2013, respectively. 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 $4.7 million for the year ended December 31, 2014, an increase of $0.3 million, or 7.2%, compared to the prior year, primarily as a result of increased sales resources associated with the Telerhythmics business, as well as additional investment in Diagnostic Imaging sales resources, offset partially by reduced marketing costs associated with new and developmental product offerings. Marketing and sales expenses as a percentage of total revenues were 8.5% and 8.9% for the years ended December 31, 2014 and 2013, respectively. We expect marketing and sales expense for fiscal year 2015 to be relatively consistent with, or increase marginally compared to, fiscal year 2014. 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 $8.3 million for the year ended December 31, 2014, an increase of $0.2 million, or 2.8%, compared to the prior year, primarily as a result of increased costs related to the administration of the Telerhythmics business, partially offset by less cost associated with our 2014 annual shareholder meeting compared to the $0.7 million of legal costs incurred in the year ended December 31, 2013 related to the 2013 proxy contest and subsequent legal proceedings associated with the proxy contest. General and administrative expenses were 15.0% of total revenue for the year ended December 31, 2014 compared to 16.4% for the prior year. We expect general and administrative expense to generally approximate the level of expense in the year ended December 31, 2014 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). The Diagnostic Imaging restructuring initiative was completed as of June 30, 2014. A total of $1.8 million of costs were incurred related to the Diagnostic Imaging restructuring initiative, with $29 thousand incurred in the year ended December 31, 2014 and $1.7 million incurred in the year ended December 31, 2013. 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 had 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 for a separate 21,300 square foot facility to house our Diagnostic Imaging operations. As a result of the facilities restructuring initiative, we incurred a total of $0.7 million of restructuring charges, all of which were incurred during the year ended December 31, 2014. All restructuring efforts associated with this initiative were complete as of December 31, 2014. We do not expect to incur restructuring charges in fiscal year 2015, although will continue to assess the need to restructure our business to address market changes and achieve corporate objectives. 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. 27 Table Of Contents Comparison of Years Ended December 31, 2013 and 2012 Revenues Consolidated. 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 Diagnostic Services business segment. Diagnostic Services revenue accounted for 75.3% of total revenues for the year ended December 31, 2013, compared to 71.4% for the prior year. Diagnostic Services. Our Diagnostic Services 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. 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, 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 Diagnostic Services 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. Diagnostic Services. Cost of Diagnostic Services 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, primarily as a result of increased revenues, partially offset by lower radiopharmaceutical costs and depreciation expense. Diagnostic Services 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. Diagnostic Services gross profit as a percentage of Diagnostic Services 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 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 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. 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 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. Research and development expenses were 8.4% and 25.7% of Diagnostic Imaging revenue for the years ended December 31, 2013 and 2012, respectively. Marketing and Sales. 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. General and Administrative. 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, 28 Table Of Contents 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. Restructuring. On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly reduce costs (the Diagnostic Imaging restructuring initiative). Overall, this restructuring resulted in total charges of $1.7 million in the year ended December 31, 2013. On January 27, 2014, we announced a plan to exit our 47,000 square foot former headquarter facility in Poway, California (the Facilities restructuring initiative). This action was undertaken as the facility had 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 for a separate 21,300 square foot facility to house our Diagnostic Imaging operations. As a result of the facilities restructuring initiative, we incurred a total of $0.7 million of restructuring charges, all of which were incurred during the year ended December 31, 2014. All restructuring efforts associated with this initiative were completed as of December 31, 2014. We do not expect to incur restructuring charges in fiscal year 2015, although we will continue to assess the need to restructure our business to address market changes and achieve corporate objectives. 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. 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. Liquidity and Capital Resources Overview We generated $4.3 million of positive cash flow from operations during the year ended December 31, 2014, 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 dividend payments and share repurchases, 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, 2014, we had cash, cash equivalents, and securities available-for-sale of $22.0 million. We generally invest our cash reserves in money market funds, U.S. treasury, and corporate debt securities. In addition, our shelf registration statement on Form S-3, which was declared effective on January 28, 2015, provides us with increased capital flexibility to pursue corporate objectives by allowing us to offer and sell up to $20.0 million of securities. We require capital principally for capital expenditures, acquisition activity, 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, cardiac monitoring devices, ultrasound machines, vans, and computer hardware and software. Based upon our current level of expenditures, we believe our current working capital, together with cash flows from operating activities, will be more than adequate to meet our anticipated cash requirements for at least the next 12 months. Cash Flows The following table shows cash flow information for the years ended December 31, 2014, 2013, and 2012 (in thousands): Year Ended December 31, Net cash provided by (used in) operating activities Net cash (used in) provided by investing activities Net cash used in financing activities 29 2014 2013 2,201 $ 4,280 $ $ (5,079) $ $ (3,894) $ (3,737) $ 766 2012 $ (1,082) $ (2,715) (728) Table Of Contents Operating Activities Net cash provided by operating activities increased by $2.1 million for the year ended December 31, 2014 compared to the prior year. The increase is primarily attributable to net income of $2.5 million generated in fiscal year 2014, an increase of $2.2 million compared to net income of $0.3 million for fiscal year 2013 driven by increased revenue, improved gross profit, and relatively consistent operating expenses. Net cash provided by operating activities increased by $3.3 million for the year ended December 31, 2013 compared to the prior year. 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. Investing Activities Net cash used in investing activities increased by $5.8 million for the year ended December 31, 2014 compared to the prior year. This increase was primarily attributable to the outlay of $3.4 million of cash to acquire Telerhythmics in the year ended December 31, 2014, compared to approximately $1.7 million of net proceeds received in the prior year from the sale of assets related to an uncommercialized surgical imaging system and associated license agreement. Net cash provided by investing activities increased by $3.5 million for the year ended December 31, 2013 compared to the prior year. 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. Financing Activities Net cash used in financing activities increased by $0.2 million for the year ended December 31, 2014 compared to the prior year. This increase was primarily attributable to $3.7 million of dividend payments during the year ended December 31, 2014, compared to $0.9 million during the year ended December 31, 2013, as well as less cash received during the year ended December 31, 2014 related to stock option exercises compared to the prior year. Offsetting the increase in cash used in financing activities for the year ended December 31, 2014 compared to the prior year were decreased share repurchases, with no share repurchases during the year ended December 31, 2014, compared to $3.6 million of cash used for share repurchases in the prior year. Net cash used in financing activities increased by $3.0 million for the year ended December 31, 2013 compared to the prior year. 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. 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, 2014 (amounts in thousands): Contractual Obligations Operating lease obligations Capital lease obligations (1) Total Contractual Obligations (1) Capital lease obligations include related interest obligations.

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 30 Table Of Contents 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. 31 Table Of Contents 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, 2014 and 2013, 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, 2014. 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. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Digirad Corporation at December 31, 2014 and 2013, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP San Diego, California March 6, 2015 32 Table Of Contents DIGIRAD CORPORATION CONSOLIDATED STATEMENTS OF COMPREHENSIVE INCOME (LOSS) (In thousands, except per share amounts) Revenues: Diagnostic Services Diagnostic Imaging Total revenues Cost of revenues: Diagnostic Services Diagnostic Imaging Total cost of revenues Gross profit Operating expenses: Research and development Marketing and sales General and administrative Amortization of intangible assets Restructuring charges Gain on sale of assets and license agreement Total operating expenses Income (loss) from operations Other income (expense): Interest and other income, net Interest expense Total other income Income (loss) before income taxes Income tax benefit (expense) Net income (loss) Net income (loss) per share: Basic Diluted Shares used in per share computations: Weighted average shares outstanding—basic Weighted average shares outstanding—diluted Dividends declared per common share Net income (loss) Other comprehensive loss: Unrealized loss on marketable securities Total other comprehensive loss Comprehensive income (loss) Year ended December 31, 2014 2013 2012 $ 42,170 13,438 55,608 $ 37,171 12,205 49,376 $ 31,721 7,247 38,968 16,640 — 4,730 8,344 356 692 — 14,122 27,828 7,432 35,260 14,116 1,025 4,411 8,118 231 1,728 (1,568) 13,945 36,064 14,449 50,513 27,293 10,128 37,421 13,092 3,716 6,402 7,839 233 — — 18,190 2,518 171 (5,098) 58 (39) 19 2,537 (62) 2,475 0.13 0.13 18,571 18,878 0.20 2,475 (17) (17) 2,458 $ $ $ $ $ $ 63 (15) 48 219 45 264 0.01 0.01 18,789 19,159 0.05 264 (19) (19) 245 $ $ $ $ $ $ 101 (4) 97 (5,001) 77 (4,924) (0.26) (0.26) 19,274 19,274 — (4,924) (16) (16) (4,940) $ $ $ $ $ $ See accompanying notes to audited consolidated financial statements. 33 DIGIRAD CORPORATION CONSOLIDATED BALANCE SHEETS (In thousands, except share amounts) Table Of Contents Assets: Current assets: Cash and cash equivalents Securities available-for-sale Accounts receivable, net Inventories, net Other current assets Restricted cash Total current assets Property and equipment, net Intangible assets, net Goodwill Other assets Total assets Liabilities: Current liabilities: Accounts payable Accrued compensation Accrued warranty Deferred revenue Other current liabilities Total current liabilities Other liabilities Total liabilities Commitments and contingencies (Note 7) Stockholders’ equity: Preferred stock, $0.0001 par value: 10,000,000 shares authorized;

The Company Digirad Corporation (Digirad), a Delaware corporation, is one of the largest national providers of in-office nuclear cardiology imaging and ultrasound imaging services, and also provides cardiac event monitoring services. These services are provided to physician practices, hospitals, and imaging centers through our Diagnostic Services reportable segment. Digirad also sells medical diagnostic imaging systems, including solid-state gamma cameras, for nuclear cardiology and general nuclear medicine applications, as well as provides service on the products sold, through our Diagnostic Imaging reportable segment. These two reportable segments, Diagnostic Services 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. The financial results for the year ended December 31, 2014 include the financial results of Telerhythmics, LLC for the period since the acquisition date of March 13, 2014. See Note 3 to the audited consolidated financial statements for more information related to the acquisition of Telerhythmics, LLC. Revenue Recognition We derive revenues primarily from providing in-office services related to the performance of cardiac diagnostic imaging procedures, cardiac event monitoring, 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. Diagnostic Services imaging services 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. Diagnostic Services imaging services are generally billed on a per-day basis under annual contracts for nuclear diagnostic imaging, which specify the number of days of service to be provided, or on a flat rate month-to-month basis for ultrasound imaging. Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. We also receive reimbursement directly from patients through co-pays and self-pay arrangements. Billings for services reimbursed by third-party payors, including Medicare, are recorded as revenue net of contractual allowances. Contractual allowances are estimated based on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. Adjustments to the estimated receipts, based on final settlement with the third party payors, are recorded upon settlement. 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 sales. 37 Table Of Contents 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 (VSOE) of selling price nor 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 contractual allowances, 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. For 2014, Emory Healthcare represented 10.9% of our consolidated revenues and 14.3% of our Diagnostic Services revenues. Prior to 2014, no single customer exceeded 10% of our consolidated revenues. We believe we have good relations with Emory Healthcare, however, if we were to lose Emory Healthcare as a customer, it would likely have a material adverse affect on our operations. 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, contingent consideration, 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 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, 2014 and 2013. 38 Table Of Contents The following table sets forth the composition of securities available-for-sale as of December 31, 2014 and 2013 (in thousands): As of December 31, 2014 Corporate debt securities Corporate debt securities As of December 31, 2013 Corporate debt securities Corporate debt securities Maturity in Years Amortized Cost Unrealized Fair Value Gains Losses Less than 1 year 1-3 years $ $ 4,650 $ — $ 3,304 — 7,954 $ — $ (5) $ (14) (19) $ 4,645 3,290 7,935 Maturity in Years Amortized Cost Unrealized Fair Value Gains Losses Less than 1 year 1-3 years $ $ 2,176 5,499 7,675 $ $ 5 — 5 $ — $ 2,181 (7) (7) $ 5,492 7,673 $ Allowance for Doubtful Accounts, Billing Adjustments, and Contractual Allowances Accounts receivable consist principally of trade receivables from customers and government or third-party healthcare insurance providers, 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. The 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. Within Diagnostic Services, we record adjustments and credit memos that represent billing adjustments subsequent to the performance of service. A provision for billing adjustments is charged against Diagnostic Services revenues. Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. Accounts receivable related to cardiac event monitoring are recorded at the time revenue is recognized, net of contractual allowances. Contractual allowances are estimated based on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. A provision for contractual allowances is charged against Diagnostic Services revenues.

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 39 Table Of Contents 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. The following table summarizes our reserves for excess and obsolete inventory as of and for the years ended December 31, 2014, 2013, and 2012 (in thousands): Balance at December 31, 2011 Provision adjustment Write-offs and scrap Balance at December 31, 2012 Provision adjustment Write-offs and scrap Balance at December 31, 2013 Provision adjustment Write-offs and scrap Balance at December 31, 2014 Reserve for Excess and Obsolete Inventories (1) $ $ 1,593 1,164 (192) 2,565 210 (232) 2,543 (630) — 1,913 (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 are 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. Estimated useful lives for intangibles range from 5 to 9 years years for customer relationships, 9 years for trademarks, 8 to 15 years for patents, and 5 years for covenants not to compete. 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, 2014, 2013, and 2012. 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, 2014, we held $0.5 million of money market funds that are restricted from withdrawal as they are held as collateral for letters of credit related to our workers' compensation insurance policy and the building lease for the Poway, CA facility. 40 Table Of Contents 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. 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. Both restructuring initiatives were complete as of December 31, 2014. See Note 11 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 $0.5 million, $0.2 million, and $0.2 million for the years ended December 31, 2014, 2013, and 2012, 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, 2014, 2013, and 2012 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 Year Ended December 31, 2014 2013 2012 $ $ 137 286 (247) 176 $ $ 326 149 (338) 137 $ $ 297 453 (424) 326 Advertising costs are expensed as incurred. Total advertising costs for each of the years ended December 31, 2014, 2013, and 2012 were $0.2 million, $0.3 million, and $0.5 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 5,063, 44,522, and 221,335 vested restricted stock units for the years ended December 31, 2014, 2013, and 2012, respectively. 41 Table Of Contents 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): Net income (loss) Shares used to compute basic net income (loss) per share Dilutive potential common shares: Stock options Restricted stock units Shares used to compute diluted net income (loss) per share Basic net income (loss) per share Diluted net income (loss) per share Year Ended December 31, 2014 2013 $ 2,475 $ 264 $ 2012 (4,924) 18,571 18,789 19,274 307 — 18,878 359 11 19,159 — — 19,274 $ $ 0.13 0.13 $ $ 0.01 0.01 $ $ (0.26) (0.26) Antidilutive common stock equivalents are excluded from the computation of diluted earnings per share. Stock options and restricted stock units are antidilutive when the assumed proceeds per share are greater than the average market price of the common shares. In addition, in periods where net losses are incurred, stock options and restricted stock units with assumed proceeds per share less than the average market price of the common shares become antidilutive as well. The number of common share equivalents that were antidilutive due to the assumed proceeds per share being greater than the average market price of the common shares were 66,917, 177,891, and 268,662 for the years ended December 31, 2014, 2013, and 2012, respectively. Since we incurred a net loss for the year ended December 31, 2012, an incremental 403,670 common share equivalents were excluded from the computation of diluted net loss per share for year ended December 31, 2012, as its effect would be antidilutive due to the net loss position. Other Comprehensive Loss Other comprehensive 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 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. Acquisitions On March 13, 2014, we acquired 100% of the membership interest of Telerhythmics, LLC (Telerhythmics), a provider of 24- hour cardiac monitoring services. We paid to the sellers of the membership interest (the Sellers) aggregate up-front consideration 42 Table Of Contents of $3.4 million and assumed approximately $131,000 in debt. In addition, there is an aggregate earn-out opportunity of up to $501,000 from the period March 14, 2014 through December 31, 2016 based on the Telerhythmics business meeting certain earnings before interest, taxes, depreciation and amortization (EBITDA) milestones. The acquisition was accounted for as a business combination. See Note 3 to the audited consolidated financial statements for further information. 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. 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. In May 2014, the FASB issued guidance that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers which supersedes most current revenue recognition guidance, including industry-specific guidance. The guidance provides that an entity recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. The guidance allows for either full retrospective or modified retrospective adoption and will become effective for us in the first quarter of 2017. We are currently evaluating the alternative transition methods and the potential effects of the adoption of this guidance on our financial statements. NOTE 3. Acquisition of Telerhythmics, LLC On March 13, 2014, we acquired 100% of the membership interest of Telerhythmics, LLC (Telerhythmics), a provider of 24- hour cardiac monitoring services. Telerhythmics and Digirad each have a very similar customer base, yet with only minor overlaps in current customers. We believe this similar customer base will allow us to leverage each company’s strengths to grow sales and also diversify Digirad’s service offerings. We paid to the sellers of the membership interest (the Sellers) aggregate up-front consideration of $3.4 million and assumed approximately $131,000 in debt. In addition, there is an aggregate earn-out opportunity of up to $501,000 from the period March 14, 2014 through December 31, 2016 based on the Telerhythmics business meeting certain earnings before interest, taxes, depreciation and amortization (EBITDA) milestones. The Sellers will receive fifty percent (50%) of the EBITDA generated by the Telerhythmics business in excess of the EBITDA milestone amounts, which are as follows: • • • $415,000 of EBITDA for the period from the closing date through December 31, 2014, $825,000 of EBITDA for the period from January 1, 2015 through December 31, 2015; and $825,000 of EBITDA for the period from January 1, 2016 through December 31, 2016. At December 31, 2014, we have estimated the fair value of the contingent earn-out opportunity to be $229,000. The earn-out opportunity is estimated based on expected performance of the business over the period from January 1, 2015 through December 31, 2016, utilizing an income approach. No earn-out consideration was earned by the Sellers for the period from the closing date through December 31, 2014. It is reasonably possible that our estimate of the earn-out potential could change in the near term. Any adjustment in the estimated earn-out opportunity until settled will be recorded as a gain or loss to current operations in the period the estimate changes. As of December 31, 2014, the allocation of the purchase price to the assets acquired and liabilities assumed on the acquisition date was as follows (in thousands): 43 Table Of Contents Assets Current assets: Accounts receivable, net Other current assets Total current assets Property and equipment, net Intangible assets, net Goodwill Total assets Liabilities Current liabilities: Accounts payable Accrued compensation Other accrued liabilities Current portion of long-term debt Total current liabilities Other liabilities Total liabilities Allocation of purchase price $ $ $ $ 256 34 290 290 2,580 1,153 4,313 36 169 356 131 692 174 866 The long-term debt was paid in full on March 28, 2014. The goodwill recognized as part of the transaction primarily represents synergies between Digirad and Telerhythmics that were not separately identified as part of the acquisition valuation process. Telerhythmics activities are considered their own operating segment, which is aggregated into our Diagnostic Services reportable segment (formerly Digirad Imaging Solutions). The resulting goodwill from the acquisition is expected to be deductible for federal and state tax reporting purposes. The below tables display estimated pro forma results had the business acquisition been completed as of January 1, 2013. In deriving the pro forma results, we utilized the historical operating results of Telerhythmics and adjusted for the impact of the purchase accounting and transaction costs as if the acquisition occurred on January 1, 2013. (in thousands) Revenues Net income Year Ended December 31, (unaudited) 2014 2013 $ $ 56,763 2,688 $ $ 55,494 247 Included within our consolidated operating results for the year ended December 31, 2014 are Telerhythmics operations for the period March 14, 2014 through December 31, 2014 as follows: (in thousands) Revenues Net loss Year Ended December 31, 2014 (unaudited) $ $ 3,926 (777) Included within the results for Telerhythmics is approximately $155,000 of transaction costs related to the acquisition. These costs are classified as general and administrative expenses in the consolidated statements of comprehensive income (loss). 44 Table Of Contents NOTE 4.

Fair Value Measurements December 31, 2014 December 31, 2013 $ $ 333 197 177 348 155 151 — 428 367 275 242 174 151 134 50 381 $ 1,789 $ 1,774 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, 2014 and 2013 (in thousands): Assets: Corporate debt securities Liabilities: Acquisition related contingent consideration Assets: Corporate debt securities At Fair Value as of December 31, 2014 Level 1 Level 2 Level 3 Total $ $ — $ 4,645 $ — $ 4,645 — $ — $ 229 $ 229 At Fair Value as of December 31, 2013 Level 1 Level 2 Level 3 Total $ — $ 2,181 $ — $ 2,181 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. The acquisition related contingent consideration is related to our acquisition of Telerhythmics on March 13, 2014. We reassess the fair value of the contingent consideration to be settled in cash related to our acquisition of Telerhythmics on a quarterly basis using the income approach, which is a Level 3 measurement. The estimation of the fair value of the contingent consideration 46 Table Of Contents requires significant management judgment, including estimating future cash flows associated with the Telerhythmics business and determining the associated discount rate. The maximum possible consideration to be paid is $501,000. No contingent consideration was earned or paid as of December 31, 2014, and no minimum amount is guaranteed to be paid. At the acquisition date, the contingent consideration was valued at $220,000. Upon our reassessment at December 31, 2014, we adjusted the estimated value of the contingent consideration to $229,000. The change in contingent consideration is recorded as general and administrative expense in the Consolidated Statements of Comprehensive Income (Loss). See Note 3 for further detail regarding contingent consideration related to our acquisition of Telerhythmics. NOTE 6. Goodwill Goodwill has been recorded related to the acquisition of Ultrascan in 2007 and the acquisition of Telerhythmics in 2014. The related goodwill has been recorded within two separate reporting units within our Diagnostic Services segment. As a result of our annual impairment test during the fourth quarter of 2008, we recorded a $2.5 million impairment loss on the goodwill related to the Ultrascan acquisition, adjusting the related goodwill to its implied carrying value of $0.2 million. During the year ended December 31, 2014, we recorded $1.2 million of goodwill as a result of acquisition of Telerhythmics, bringing total goodwill to its current carrying value of $1.3 million. We determined the implied fair value of the goodwill for Telerhythmics utilizing the discounted cash flow method under the income approach. Under the income 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. During the fourth quarter of 2014, we performed our annual goodwill impairment test. We performed a qualitative assessment of all reporting units to estimate whether it is more likely than not that the fair value of each reporting unit was less than its carrying amount. In performing this qualitative assessment, we assessed relevant events and circumstances that may impact the fair value and the carrying amount of each reporting unit. Factors that were considered included, but were not limited to, the following: (1) macroeconomic conditions; (2) industry and market conditions; (3) overall financial performance and expected financial performance; (4) other entity specific events. Based on the results of this qualitative assessment, we determined that it is more likely than not that the carrying value of the Ultrascan related reporting unit is less than its fair value and, thus, the two-step quantitative analysis was not required. In regards to the Telerhythmics related reporting unit, we performed the first step of the goodwill impairment test which involves comparing the fair value of the reporting unit with the associated carrying value, including goodwill. We determined the fair value of the reporting unit using the income valuation approach. The reporting unit’s fair value exceeded the associated carrying amount of the reporting unit; therefore the second step of the goodwill impairment test was not necessary. No impairment loss was recorded for the years ended December 31, 2014, 2013, or 2012. NOTE 7. Commitments and Contingencies Leases We currently lease facilities and certain automotive equipment under non-cancelable operating leases expiring from January 1, 2015 through November 30, 2021. 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 current and long-term liabilities. Rent expense was approximately $1.3 million for the year ended December 31, 2014, and $1.4 million for the years ended December 31, 2013 and 2012. As of December 31, 2014, 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 March 31, 2018. 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, 2014 are as follows (in thousands): 2015 2016 2017 2018 2019 Thereafter Total minimum lease payments 47 Operating Leases Capital Leases $ $ 1,108 875 567 490 493 669 4,202 $ $ 383 308 123 5 — — 819 Table Of Contents 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 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. NOTE 8. Share-Based Compensation At December 31, 2014, we have two active equity incentive plans, the 2011 Inducement Stock Incentive Plan (the 2011 Plan) and the 2014 Equity Incentive Award Plan (the 2014 Plan), (collectively the Plans), under which stock options, restricted stock units, and other stock based awards 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 four years. Under the Plans, we are authorized to issue an aggregate of 1,856,733 shares of common stock. As of December 31, 2014, the Plans had 1,131,432 shares available for future issuance. The number of shares reserved for issuance under the 2014 Plan is subject to increase by any shares under the 2004 Equity Incentive Award Plan (the 2004 Plan) that are forfeited, expire, or are canceled. As of December 31, 2014, the number of shares provided for issuance under the 2014 Plan due to forfeited, expired, and canceled shares under the 2004 Plan was 1,500 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, 2014, 2013, and 2012 was $0.70, $1.06, and $1.05 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 Year Ended December 31, 2014 2013 2012 43% 4.1 1.2% 5.7% 56% 4.6 0.9% — 59% 6.0 1.2% — 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. The expected dividend yield is based on the current annualized dividend rate per share divided by the historical average stock price. At the time of the grants, for the years ended December 31, 2013 and 2012, 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. 48 Table Of Contents A summary of our stock option award activity as of and for the year ended December 31, 2014 is as follows (in thousands, except per share data): Options outstanding at December 31, 2013 Options exercisable at December 31, 2013 Options granted Options forfeited Options expired Options exercised Options outstanding at December 31, 2014 Options exercisable at December 31, 2014 Weighted- Average Exercise Price per Share Weighted- Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value Number of Shares 856 501 750 (45) (5) (98) 1,458 553 $ $ $ $ $ 1.93 1.75 3.38 3.21 6.98 1.92 2.62 1.82 5.0 3.4 $ $ 2,537 1,403 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, 2014, total unrecognized compensation cost related to unvested stock options was $0.5 million, which is expected to be recognized over a weighted-average period of 1.8 years. Upon exercise, we issue new shares of common stock. Cash received from stock option exercises was $0.2 million during the year ended December 31, 2014, $0.9 million during the year ended December 31, 2013, and $0.3 million for the year ended December 31, 2012. 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 9. The total intrinsic value of stock options exercised was $0.1 million during the year ended December 31, 2014, $0.9 million during the year ended December 31, 2013, and less than $0.1 million during the year ended 2012. 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. Vesting of the restricted stock awards is subject to service conditions, as well as the attainment of additional performance objectives for certain of the awards. The weighted- average grant date fair value of the restricted stock units was $3.81 and $1.82 per share during the years ended December 31, 2014 and 2012, 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, 2014 is as follows (in thousands, except per share data): Non-vested restricted stock units outstanding at December 31, 2013 Granted Forfeited Vested Non-vested restricted stock units outstanding at December 31, 2014 Number of Shares Weighted- Average Grant Date Fair Value Per Share — $ 88 — — 88 $ — 3.81 — — — The following table summarizes information about restricted stock units that vested during the years ended December 31, 2014, 2013, and 2012 based on service conditions (in thousands): Fair value on vesting date of vested restricted stock units 49 Year Ended December 31, 2014 2013 $ — $ 136 2012 $ 350 Table Of Contents At December 31, 2014, total unrecognized compensation cost related to non-vested restricted stock units was $0.3 million, which is expected to be recognized over a weighted-average period of 3.5 years. 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, 2014, 2013, and 2012 was allocated as follows (in thousands): Cost of revenues: Diagnostic Services Diagnostic Imaging Research and development Marketing and sales General and administrative Share-based compensation expense NOTE 9.

Federal loss carryforwards will begin to expire in 2018 unless previously utilized. State loss carryforwards of less than $0.1 million expired in 2014, and approximately $4.1 million is set to expire in 2015 unless previously utilized. We also have federal and California research and other credit carryforwards of approximately $1.8 million and $2.1 million, as of December 31, 2014, respectively. The federal credits will begin to expire in 2018. The California research credits have no expiration. 50 Table Of Contents Pursuant to Internal Revenue Code Sections 382 and 383, use of our net operating loss and credit carryforwards may be limited because of a cumulative change in ownership greater than 50% which may have occurred or which may occur in the future. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended December 31, 2014. Such objective evidence limits the ability to consider other subjective evidence such as our projections for future income. On the basis of this evaluation, as of December 31, 2014, a valuation allowance has been recorded as management cannot conclude that it is more likely than not that the existing deferred tax assets will be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as our projected future income. Our net deferred tax assets (liabilities) consisted of the following (in thousands): Deferred tax assets (liabilities): Net operating loss carryforwards 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 (liabilities) December 31, 2014 2013 $ $ 33,732 1,950 1,417 2,097 1,079 40,275 (237) (40,059) $ (21) $ 34,727 1,928 1,273 2,425 830 41,183 (300) (40,883) — 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, 2014 $ 1,553 — — — — $ 1,553 2013 $ 1,539 5 64 (55) — $ 1,553 2012 $ 1,621 25 81 (252) 64 $ 1,539 Included in the unrecognized tax benefits of $1.6 million at December 31, 2014 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 2009; 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 expense. There were no accrued interest and penalties as of December 31, 2014 and 2013 ,and no interest and penalties were recognized during the years ended December 31, 2014, 2013, and 2012. NOTE 10. Employee Retirement Plan We have 401(k) retirement plans under which employees may contribute up to 100% of their annual salary, within IRS limits. The Company contributions to the retirement plans totaled $0.2 million for each of the years ended December 31, 2014, 2013, and 2012. 51 Table Of Contents NOTE 11. Restructuring Charges 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 had 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 incurred a total of $0.7 million of restructuring charges, all of which were incurred during the year ended December 31, 2014. The charges are comprised of lease termination, moving and other related costs. All restructuring efforts associated with this initiative were complete as of December 31, 2014. The following table includes information regarding our Facilities restructuring initiative: (in thousands) Accrued at December 31, 2013 Accrued Costs Cash Payments and Other Reductions Accrued at December 31, 2014 Total Facilities restructuring initiative $ — $ 663 $ 660 $ 3 Accrued Facilities restructuring initiative charges at December 31, 2014 are included in the accounts payable line item in the consolidated balance sheets. All Facilities restructuring initiative charges for the year ended December 31, 2014 are included in the Diagnostic Imaging segment. 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 Diagnostic Services business (the Diagnostic Imaging restructuring initiative). The Diagnostic Imaging restructuring initiative included 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 the Diagnostic Imaging restructuring initiative, we incurred a total of $1.8 million in restructuring charges, the majority of which were incurred during fiscal year 2013. Included in the total Diagnostic Imaging restructuring initiative charges are $1.6 million of employee related costs, with the remaining costs consisting of contract termination costs and other related costs. All restructuring efforts associated with this initiative were complete as of June 30, 2014. The following table includes information regarding our Diagnostic Imaging restructuring initiative: (in thousands) Accrued at December 31, 2013 Accrued Costs Cash Payments and Other Reductions Accrued at December 31, 2014 Total Diagnostic Imaging restructuring initiative $ 489 $ 29 $ 516 $ 2 All accrued Diagnostic Imaging restructuring initiative charges at December 31, 2014 are included in the accrued compensation line item in the consolidated balance sheets. All the Diagnostic Imaging restructuring initiative charges for the year ended December 31, 2014 are included in the Diagnostic Imaging segment. NOTE 12. 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 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. 52 Table Of Contents 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. 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 13. 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 and 2012, we repurchased 1,514,843 and 490,816 shares of our common stock, respectively, under the stock buyback program. During the year ended December 31, 2014, we did not repurchase any of our common stock. As of December 31, 2014, an aggregate of $6.3 million remains authorized for stock buyback under the program. NOTE 14. 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, 2014. There is no impact to the Company's financial results as a result of the adoption of the rights plan for the years ended December 31, 2014 and 2013. NOTE 15. 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. Our operating segments include Diagnostic Imaging, Digirad Imaging Solutions, and cardiac event monitoring from our Telerhythmics acquisition on March 13, 2014 (See Note 3). For financial reporting purposes, we aggregate Digirad Imaging Solutions and cardiac event monitoring due to their similar economic and operational characteristics. Summarized annual data for segments are as follows (in thousands): 53 Table Of Contents Gross profit by segment: Diagnostic Services Diagnostic Imaging Consolidated gross profit Income (loss) from operations by segment: Diagnostic Services Diagnostic Imaging (2) Consolidated income (loss) from operations Depreciation and amortization of tangible and intangible assets by segment: Diagnostic Services Diagnostic Imaging Consolidated depreciation and amortization Identifiable assets by segment: Diagnostic Services Diagnostic Imaging Consolidated assets Year ended December 31, 2014 (1) 2013 2012 $ $ $ $ $ $ 8,771 4,321 13,092 (48) (5,050) (5,098) 1,814 317 2,131 $ $ $ $ $ $ $ $ 10,449 $ 6,191 9,343 4,773 16,640 $ 14,116 220 2,298 2,518 1,672 263 1,935 $ $ $ $ 30 141 171 1,436 477 1,913 December 31, 2014 (1) 2013 18,724 $ 11,874 23,177 29,577 41,901 $ 41,451 (1) On March 13, 2014, we acquired 100% of the membership interest of Telerhythmics, LLC. The results of Telerhythmics are included in Diagnostic Services since the acquisition date (See Note 3). (2) Included in the Diagnostic Imaging income from operations for the year ended December 31, 2014, are approximately $0.7 million of charges associated with our Diagnostic Imaging and Facilities restructuring initiatives (See Note 11). Included in the Diagnostic Imaging income from operations for the year ended December 31, 2013, are approximately $1.7 million of charges associated with our Diagnostic Imaging restructuring initiative, 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 12). NOTE 16. 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 2014 and 2013 are as follows (in thousands, except per share data): 54 Table Of Contents Fiscal 2014 (1) Revenues Gross profit Income (loss) from operations (2) Net income (loss) Net income (loss) per common share—basic (3) Net income (loss) per common share—diluted (3) Fiscal 2013 Revenues Gross profit Income (loss) from operations Net income (loss) Net income (loss) per common share—basic (3) Net income (loss) per common share—diluted (3) 1st Quarter 2nd Quarter 3rd Quarter 4th Quarter $ $ $ $ $ $ $ $ $ $ $ $ 12,997 $ 14,587 3,442 $ (155) $ (148) $ (0.01) $ (0.01) $ 4,505 825 823 0.04 0.04 $ $ $ $ $ $ 13,881 4,409 1,032 1,028 0.06 0.05 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 $ $ $ $ $ $ $ $ $ $ $ $ 14,143 4,284 816 772 0.04 0.04 12,527 3,688 780 787 0.04 0.04 (1) On March 13, 2014, we acquired 100% of the membership interest of Telerhythmics, LLC. The results of Telerhythmics are included in Diagnostic Services since the acquisition date (See Note 3). (2) Included in the income (loss) from operations for the first, second, third, and fourth quarter of 2014, are approximately $0.4 million, $0.1 million, $0.1 million, and less than $0.1 million of charges, respectively, associated with our Diagnostic Imaging and Facilities restructuring initiatives (See Note 11). (3) 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 17. Subsequent Events Dividend On February 2, 2015, the Company announced a dividend of $0.05 payable to shareholders of record as of February 13, 2015. The dividend was paid on February 23, 2015. MD Office Solutions, Inc. Acquisition On March 5, 2015, we entered into an Agreement of Merger and Plan of Reorganization (the Merger Agreement) with the Stockholders party thereto (Sellers), to acquire MD Office Solutions, Inc. (MD Office). Total consideration related to the Merger Agreement paid to the Sellers was 610,000 shares of common stock of Digirad Corporation, with a total value at closing of $2,684,000. The Company issued new shares for the consideration. In addition, there is an earn-out opportunity of up to $400,000 in cash over approximately three years based on the MD Office business meeting certain earnings before interest, taxes, depreciation and amortization (EBITDA) milestones. The Sellers will receive fifty percent of the EBITDA generated by the MD Office business in excess of the EBITDA milestone amounts, which is $650,000 for each of the annual periods ending December 31, 2015, 2016 and 2017, with the target for 2015 being prorated based on the close date. The Merger Agreement is also subject to a post-closing purchase price adjustment based on the final working capital balance, as defined in the Merger Agreement, as well as a Registration Rights Agreement related to the common shares provided to the Sellers as part of the consideration. 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. A determination of the acquisition-date fair values of the assets acquired and the liabilities assumed is pending the completion of an independent appraisal and other evaluations and therefore further disclosures have not been made. 55 Table Of Contents ITEM 9. None. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURES 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. In connection with our acquisition of Telerhythmics, certain areas of internal control over financial reporting changed. These areas are primarily related to integrating corporate functions at Digirad that previously existed at Telerhythmics. The functions and related internal controls that were affected as a result of the acquisition of Telerhythmics are financial reporting, human resources, and information technology. Certain control structure items remain in operation at Telerhythmics, primarily related to the processing and billing of revenues, and collection of those revenues. The control structure at Digirad has been modified to appropriately oversee and incorporate these activities into the overall control structure. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. Management does not expect, however, that our disclosure controls and procedures will prevent or detect all errors and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. (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, 2014. 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. ITEM 9B. OTHER INFORMATION Tax Benefit Preservation Plan On May 23, 2013, we entered into a Tax Benefit Preservation Plan with American Stock Transfer & Trust Company, which was amended on November 11, 2013, to correct certain ambiguities. The Tax Benefit Preservation Plan 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 56 Table Of Contents substantially limited due to an “ownership change,” as defined in Section 382 of the Internal Revenue Code. In connection with the adoption of the tax benefit preservation plan, we declared a dividend distribution of one right for each outstanding share of Digirad common stock to stockholders of record as of the close of business on June 4, 2013. Each right entitles the registered holder to purchase from Digirad one one-thousandth of a share of Series B Participating Preferred Stock of Digirad at an exercise price of $20.00 per one one-thousandth of a share of Series B Participating Preferred Stock, subject to adjustment. As more fully described in the Tax Benefit Preservation Plan, the rights become exercisable following (i) the 10th business day (or such later date as may be determined by our 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 Digirad or (ii) the 10th business day (or such later date as may be determined by our 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 Digirad. The Tax Benefit Preservation Plan continues in full force and effect. Preferred Stock Rights Agreement Prior to entering into the Tax Benefit Preservation Plan, the Company had a pre-existing Preferred Stock Rights Agreement, which was designed to deter, among other things, coercive takeover tactics, including an acquisition by an acquiring person of 20% or more of the shares of the Company’s common stock. In light of the adoption of the Tax Benefit Preservation Plan, on March 5, 2015, we entered into a First Amendment to the Preferred Stock Rights Agreement with American Stock Transfer & Trust Company pursuant to which the Final Expiration Date (as defined therein) was amended to be March 15, 2015. As a result of this amendment, the Preferred Stock Rights Agreement will terminate in accordance with its terms on March 15, 2015. 57 Table Of Contents PART III ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE The information required by this item regarding directors and corporate governance is incorporated by reference to our definitive Proxy Statement to be filed with the Securities and Exchange Commission in connection with the Annual Meeting of Stockholders to be held in 2015, or the “2015 Proxy Statement,” under the headings “Corporate Governance and Ethics,” “Election of Directors,” and “Section 16(a) Beneficial Ownership Reporting Compliance.” We have adopted a Code of Business Ethics and Conduct (“Ethics Code”) that applies to all our officers, directors, employees and contractors.
