We have historically experienced seasonality in all of our business prospects are uncertain andbusinesses, volatility due to the seasonalitychanging healthcare environment, the variable supply of our DIS leasing services business.

        Our revenueradiopharmaceuticals, and results of operations at any given time will be primarilydownturns based on the following factors, many of which we cannot control:

•

physician, healthcare provider and patient acceptance of our products and services;



•

demand and pricing of our products and services;



•

success and timing of new product offerings, acquisitions, licenses or other significant events by us or our competitors;



•

our ability to establish and maintain a productive manufacturing, marketing, sales and distribution force;



•

the ability of our suppliers to timely provide us with an adequate supply of necessary components;



•

timing and magnitude of our expenditures;



•

our ability to reduce our expenses, including our debt service obligations, quickly enough to respond to any declines in revenue;



•

regulatory approvals and legislative changes affecting the products we may offer or those of our competitors;



•

the effect of competing technological and market developments;



•

our addition or termination of research programs or funding support;



•

levels of third-party reimbursement for our products and services;



•

interruption in the manufacturing or distribution of our products and services; and



•

changes in our ability to obtain FDA approval or clearance for our products.

        Additionally, we have experienced seasonality in the leasing services offered by DIS.changing U.S. economy. While our physicianscustomers are typically obligated to pay us for all leaseimaging days to which they have committed, our contracts permit some flexibility in scheduling when services are to be performed. This accounts for some of the seasonality of our DIS revenues. For example, our daily services have typically declined from our second fiscal quarter to our third fiscal quarter due to summer holidays and vacation schedules. We have also experienced declining daily services in December due to holidays and in our first quarter due to weather conditions in certain parts of the United States. We cannot predict with certainty the degree to which seasonal circumstances such as the summer slowdown, winter holiday variationsvacations, and weather conditions may makeaffect the results of our revenue unpredictable or lead tooperations. We have also experienced fluctuations in demand of our diagnostic imaging product sales 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 products are booked during the last month of each quarterly operating resultsaccounting period, and often there can be a large amount in the future.

        For these reasons, we believe that quarterly sales and operating resultslast month of the year. As such, a delivery delay of only a few days may vary significantly in the future and that period-to-periodimpact quarter-to-quarter comparisons of our results of operations are not necessarily meaningful and should not be relied upon as indicators of future performance. We cannot assure you that ouroperations. Moreover, the sales will increase or be sustained in future periods. Accordingly, we may experience significant, unanticipated quarterly losses. Because of these and other factors, our operating results in one or more future quarters may fail to meet the expectations of securities analysts or investors, which could cause our stock price to decline significantly.

Our reliance on a limited number of customers may cause our sales to be volatile.

        We currently have a small number of customers, whom we typically bill after the delivery of our products and imaging services. If orders for our gamma cameras were to be cancelled, or our leasing service customers stopped using us or do not renew their lease agreements with us, our business would be adversely affected. Furthermore, in view of our small customer base, our failure to gain additional customers, the loss of any current customers or a significant reduction in the level of leasing services

15

provided to any one customer could disrupt our business, harm our reputation and adversely affect our sales.

The sales cycle for our gamma cameras is typically lengthy, which may result in significant fluctuations in our revenue.

        Our sales efforts for our gamma cameras are dependent on the capital expenditures budgets of the physicians and hospitals to which we market. Often physicians and hospitals require a significant amount of lead time to plan for a major acquisition such as the purchase of our imaging systems. We may spend substantial time, effort and expense long before we actually consummate a sale of our cameras and with no assurance that we will ultimately be successful in achieving any such sales. As a result, we may experience significant fluctuations in our revenues. Furthermore, evaluating and predicting our future sales and operating performance is difficult and may not be as accurate as it could be if we had shorter sales cycles.

Our future capital needs are uncertain and we may need to raise additional funds in the future, and such funds may not be available on acceptable terms, if at all.

        We believe that the net proceeds from this offering, together with our current cash, cash equivalents and short-term investments, will be sufficient to meet our projected operating requirements for at least the next 12 months. Our capital requirements will depend on many factors, including:

•

the revenue generated by sales of our products and services;



•

the costs associated with expanding our manufacturing, marketing, sales and distribution efforts;



•

the rate of progress and cost of our research and development activities;



•

the costs of obtaining and maintaining FDA and other regulatory clearance of our products and products in development;



•

the costs of obtaining and maintaining radioactive materials licenses and radiation safety procedures;



•

the effects of competing technological and market developments;



•

the number and timing of acquisitions and other strategic transactions; and



•

the costs associated with our expansion, if any.

        As a result of these factors, we may need to raise additional funds, and we cannot be certain that such funds will be available to us on acceptable terms, if at all. Furthermore, if we issue equity or debt securities to raise additional funds, our existing stockholders may experience dilution and the new equity or debt securities may have rights, preferences and privileges senior to those of our existing stockholders. In addition, if we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish potentially valuable rights to our future products or proprietary technologies, or grant licenses on terms that are not favorable to us. If we cannot raise funds on acceptable terms, we may not be able to expand our operations, develop new products, take advantage of future opportunities or respond to competitive pressures or unanticipated customer requirements.

Risks Related to Government Regulation

We must be licensed to handle and use hazardous materials and may be liable for contamination or other harm caused by hazardous materials that we use.

        We use hazardous and radioactive materials in our research and development and manufacturing processes, as well as in the provision of our imaging services. We are subject to federal, state and local regulations governing use, storage, handling and disposal of these materials and waste products. We are currently licensed to handle such materials in all states in which we operate, but there can be no assurances that we will be able to retain those licenses in the future. In addition, we must become licensed in all states in which we plan to expand. Obtaining those additional licenses is an expensive and time consuming process, and in some cases we may not be able to obtain those licenses at all.

        Although we believe that our procedures for use, handling, storing and disposing of these materials comply with legally prescribed standards, we cannot completely eliminate the risk of contamination or injury resulting from hazardous materials and we may incur liability as a result of any such contamination or injury. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our resources and any applicable insurance.

        We have also incurred and may continue to incur expenses related to compliance with environmental laws. Such future expenses or liability could have a significant negative impact on our business, financial condition and results of operations. Further, we cannot assure you that the cost of complying with these laws and regulations will not materially increase in the future.

Compliance with extensive product regulations could be expensive and time consuming, and any failure to comply with those regulations could harm our ability to sell and market our products and imaging services.

        U.S. and foreign regulatory agencies, including the FDA, govern the testing, marketing and registration of new medical devices or modifications to medical devices, in addition to regulating manufacturing practices, reporting, labeling and recordkeeping procedures. The regulatory process makes it longer, harder and more costly to bring our products to market, and we cannot assure you that any of our future products will be approved. All of our planned services, products and manufacturing activities, as well as the manufacturing activities of third-party medical device manufacturers who supply components to us, are subject to these regulations. Generally, we and our third-party manufacturers are or will be required to:

•

undergo rigorous inspections by domestic and international agencies;



•

obtain the prior approval of those agencies before we can market and sell our medical device products; and



•

satisfy content and format requirements for all of our sales and promotional materials.

        Compliance with the regulations of those agencies may delay or prevent us from introducing new or improvedcapital products which could in turn affect our ability to achieve or maintain profitability. We may be subject to sanctions, including monetary fines and criminal penalties, the temporary or permanent suspension of operations, product recalls and marketing restrictions, if we fail to comply with the laws and regulations applicable to our business. Our third-party component manufacturers may also be subject to the same sanctions and, as a result, may be unable to supply components for our products. Any failure to retain governmental approvals that we currently hold or obtain additional similar approvals could prevent us from successfully marketing our products and technology and could harm our operating results. Furthermore, changesis typically lengthy, particularly in the applicable governmental regulations could prevent further commercialization of our products and technologies and could harm our business.

        Even if regulatory approval or clearance of a product is granted, regulatory agencies could impose limitations on uses forhospital market, which the product may be labeled and promoted. Further, for a marketed product,

17

its manufacturer and manufacturing facilities are subject to periodic review and inspection. Later discovery of problems with a product, manufacturer or facility may result in restrictions on the product, manufacturer or facility, including withdrawal of the product from the market or other enforcement actions.

Our products are subject to reporting requirements and recalls even after receiving FDA clearance or approval, which could harm our reputation, business and financial results.

        We are subject to medical device reporting regulations that requirecause us to report to FDA or similar governmental bodies in other countries if our products cause or contribute to a death or serious injury or malfunction in a way that would be reasonably likely to contribute to death or serious injury if the malfunction were to recur. In addition, the FDA and similar governmental bodies in other countries have the authority to require the recall of our products in the event of material deficiencies or defects in design or manufacture. A government mandated or voluntary recall by us could occur as a result of component failures, manufacturing errors or design defects, including defects in labeling. Any recall would divert management attention and financial resources and harm our reputation with customers. A recall involving our product could harm the reputation of the product and our company and would be particularly harmful to our business and financial results.experience significant revenue fluctuations.

 If we fail to obtain, or are significantly delayed in obtaining, FDA clearances or approvals for future products or product enhancements, or if we fail to comply with FDA's Quality System Regulation, our ability to commercially market and distribute our products will suffer.

        Our products are subject to rigorous regulation by the FDA, and numerous other federal, state and foreign governmental authorities. In the U.S., the FDA regulates virtually all aspects of a medical device's testing, manufacture, safety, labeling, storage, recordkeeping, reporting, promotion and distribution. Our failure to comply with those regulations could lead to the imposition of administrative or judicial sanctions, including injunctions, suspensions or the loss of regulatory approvals, product recalls, termination of distribution, or product seizures. In the most egregious cases, criminal sanctions or closure of our manufacturing facilities are possible. The process of obtaining regulatory approvals to market a medical device, particularly from the FDA, can be costly and time consuming, and there can be no assurance that such approvals will be granted on a timely basis, if at all. In particular unless exempt, the FDA permits commercial distribution of a new medical device only after the device has received 510(k) clearance or is the subject of an approved Premarket Approval Application, or PMA. The FDA will clear marketing of a medical device through the 510(k) process if it is demonstrated that the new product is substantially equivalent to other 510(k)-cleared products. The PMA approval process is more costly, lengthy and uncertain than the 510(k) clearance process, and must be supported by extensive data, including data from preclinical studies and human clinical trials. Because we cannot assure you that any new products we develop, or any product enhancements, will be subject to the shorter 510(k) clearance process, significant delays in the introduction of any new products or product enhancements may occur. There is no assurance that the FDA will not require a new product or product enhancement go through the lengthy and expensive PMA approval process. Further, pursuant to FDA regulations, we can only market our products for approved uses. If our products are used for purposes other than those approved by the FDA, the FDA could object to such off-label uses.

        Our manufacturing processes and those of our third-party manufacturers are required to comply with the FDA's Quality System Regulation, or QSR, which covers the design, testing, production processes, controls, quality assurance, labeling, packaging, storage and shipping of our devices. In addition, we must engage in extensive recordkeeping and reporting and must make available our manufacturing facility and records for periodic unscheduled inspections by federal, state and foreign agencies, including the FDA. Our or our third-party manufacturers' failure to pass a QSR inspection or to comply with these and other applicable regulatory requirements could result in disruption of our operations and manufacturing delays,

18

and a failure to take adequate corrective action could result in, among other things, withdrawal of our medical device clearances, seizure or recall of our devices, or other civil or criminal enforcement actions.

        Foreign governmental authorities that regulate the manufacture and sale of medical devices have become increasingly stringent and, to the extent we now or in the future market and sell our products in foreign countries, we may be subject to rigorous regulation by those foreign governmental authorities. In such circumstances, we would rely significantly on our foreign independent distributors to comply with the varying regulations, and any failures on their part could result in restrictions on the sale of our products in foreign countries.

Modifications to our products may require new 510(k) clearances or premarket approvals, or may require us to cease marketing or recall the modified products until clearances are obtained.

        Any modification to a 510(k)-cleared device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, design, or manufacture, requires a new 510(k) clearance or, possibly, approval of a PMA. The FDA requires every manufacturer to make this determination in the first instance, but the FDA may review any manufacturer's decision. The FDA may not agree with our decisions regarding whether new clearances or approvals are necessary. If the FDA requires us to seek 510(k) clearance or PMA for modification of a previously cleared product for which we have concluded that new clearances or approvals are unnecessary, we may be required to cease marketing or to recall the modified product until we obtain clearance or approval, and we may be subject to significant regulatory fines or penalties. Further, our products could be subject to recall if the FDA determines, for any reason, that our products are not safe or effective. Any recall or FDA requirement that we seek additional approvals or clearances could result in delays, fines, costs associated with modification of a product, loss of revenue and potential operating restrictions imposed by the FDA.

We will spend considerable time and money complying with federal and state laws, regulations, and foreign regulationsother rules, and if we are unable to fully comply with such laws, regulations, and other rules, we could face substantial penalties.

We are directly, or indirectly through our clients,customers, subject to extensive regulation by both the federal government and the states and foreign countries in which we conduct our business. The laws that directly or indirectly affect our ability to operate our business, include, but are not limited to, the following:

•

including: the federal Medicare and Medicaid Anti-Kickback Law, which prohibits persons from knowinglyanti-kickback laws and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce either the referral of an individual, or furnishing or arranging for a good or service, for which payment may be made under federal healthcare programs such as the Medicare and Medicaid Programs;



•

other Medicare laws, regulations, rules, manual provisions, and regulationspolicies that prescribe the requirements for coverage and payment for services performed by us and our DIS customers, including the amount of such payment;



•

physician customers; the federal False Claims Act, which imposes civil and criminal liability on individuals and entities who submit, or cause to be submitted, false or fraudulent claims for payment to the government;



•

statutes; the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which prohibits executing a schemeas amended in 2009 under the HITECH Act that places direct legal obligations and higher liability on us with respect to defraud any healthcare benefit program, including private payorsthe security and further, requires us to comply with standards regarding the privacy and securityhandling of individually identifiablepersonal health information and conduct certain electronic transactions using standardized code sets. In addition, regulations have been issued under HIPAA that will require us to comply with additional security regulations by April 2005 and to adopt unique health identifiers for use in filing and processing healthcare claims and other transactions by May 2007;



•

the federal False Statements Statute, which prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;

19

•

the federal physician self-referral prohibition, commonly known asinformation; the Stark Law, which, in the absence of a statutory or regulatory exception, prohibits the referral of Medicare or Medicaid patients by a physician to an entity for the provision of certain designated healthcare services, if the physician or a member of the physician's immediate family has a direct or indirect financial relationship, including an ownership interest in, or a compensation arrangement with, the entity and also prohibits that entity from submitting a bill to a federal payor for services rendered pursuant to a prohibited referral;



•

Law; the federal Food, Drug and Cosmetic Act, which regulates the manufacture, labeling, marketing, distribution and sale of prescription drugs and medical devices;



•

state and foreign law equivalents of the foregoing;



•

Act; federal and state radioactive materials laws, which govern the procurement, use, transfer and storage of radioactive materials;



•

laws; state food and drug and pharmacy laws pharmacy acts and state pharmacy board regulations, which govern the sale, distribution, use, administration and prescribing of prescription drugs;



•

regulations; state laws that prohibit the practice of medicine by non-physicians and fee-splitting arrangements between physicians and non-physicians, as well asnon-physicians; state law equivalentsscope-of-practice laws; and federal rules prohibiting the mark-up of diagnostic tests to Medicare under certain circumstances. If our 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 federal Medicaregovernment. Either option will result in additional costs to us and Medicaid Anti-Kickback Lawcould negatively impact our cash reserves.

We maintain a compliance program to identify and the Stark Law, which may notcorrect 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 limited to government reimbursed itemsno assurance that our responsive actions will insulate us from liability associated with any detected compliance concerns.

If our past or services; and



•

federal laws and regulations that permit physicians to bill and receive payment for certain diagnostic tests under the Medicare Physician Fee Schedule only if certain conditions are satisfied, including the requirement that the physician personally perform, or adequately supervise the performance of, the test.

        If ourpresent operations are found to be in violation of any of the laws, regulations, rules, or policies described above or the other governmentallaws or regulations to which we or our customers are subject, we may be subject to the applicable penalty associated with the violation, including civil and criminal penalties, damages, fines, exclusion from the Medicare and Medicaidfederal or state healthcare programs, andor 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 whichthat could also have a negative impact on us. In addition, if we are required to obtain permits or licensure under these laws that we do not already possess, we may become subject to substantial additional regulation or incur significant expense. Any penalties, damages, fines, curtailment, or restructuring of our operations wouldcould adversely affect our ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations, and additional legal or regulatory change. 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'smanagement’s attention from the operation of our business, and damage our reputation. ForAlthough compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, regulations, rules, and policies, the risks cannot be entirely eliminated. Moreover, achieving and sustaining compliance with applicable federal and state privacy, security, and fraud laws may prove costly.

Healthcare policy changes could have a more detailed discussion of the various state and federal regulationsmaterial adverse effect on our business.

In response to which we are subject see "Business—Government Regulations."

Legislative or regulatory reform of theperceived increases in healthcare system may affect our ability to sell our products profitably.

        In both the United States and certain other foreign jurisdictions,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. healthcare 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 numbermaterial adverse effect on our financial position and results of legislative and regulatory proposals to change the healthcare system in ways thatoperations.

Any intrusions or attacks on our information technology infrastructure could impact our ability to conduct operations and could subject us to fines, penalties, and lawsuits related to healthcare privacy laws.

The operation of our business includes use of complex information technology infrastructures, access to the information technology networks of our customers, as well as the collection of storing of patient information that is subject to HIPAA. In recent years, attacks on corporate information technology infrastructures have become more common and more sophisticated. Attacks can range from attempts that are routinely blocked by security and related infrastructure, to intrusions that disrupt activity temporarily, to extensive intrusions that severely impact or disable a network, including ransomware that holds a network hostage until the impacted company pays a fee to the attacker. Further, attacks can specifically impact patient information stored on such networks, requiring a widespread notice to the affected population, which can be very costly. Any successful attack on our network could severely impact our ability to conduct operations and could result in lost customers. Though we carry customary insurance for notification events in the event of a patient information breach under HIPAA, our coverage may not be sufficient to cover every situation, and any notification could severely impact our customer confidence and operations.

We are subject to risks associated with self-insurance related to health benefits.

To help control our overall long-term costs associated with employee health benefits, we are self-insured up to certain limits for our health plans. As such, we are subject to risks associated with self-insurance of these health plan benefits. To limit our exposure, we have third party stop-loss insurance coverage for both individual and aggregate claim costs. However, we could still experience unforeseen and potentially significant fluctuations in our healthcare costs based on a higher than expected volume of claims below these stop-loss levels. These fluctuations 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 incur expenses and pay damages that 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.

If we cannot provide quality technical and applications support, we could lose customers and our business and prospects will suffer.

The placement of our products and the introduction of our technology at new customer sites requires the services of highly trained technical support personnel. Hiring technical support personnel is very competitive in our industry due to the limited number of people available with the necessary scientific and technical backgrounds and ability to understand our technology at a technical level. To effectively support potential new customers and the expanding needs of current customers, we will need to expand our technical support staff. If we are unable to attract, train or retain the number of highly qualified technical services personnel that our business needs, our business and prospects will suffer.

Our long-term results depend upon our ability to improve existing products and services and introduce and market new products and services successfully.

Our business is dependent on the continued improvement of our existing products and services and our development of new products and services utilizing our current or other potential future technology. As we introduce new products and services or refine, improve or upgrade versions of existing products and services, we cannot predict the level of market acceptance or the amount of market share these products and services will achieve, if any. We cannot assure you that we will not experience material delays in the introduction of new products or services in the future.

We generally sell our products and services profitably. In the United States, federalin industries that are characterized by rapid technological changes, frequent new product introductions and state lawmakers regularly proposechanging industry standards. If we do not develop new products and at times, enact new legislation establishing significant changes in the healthcare system. Recently, President Bush signed into law the Medicare Modernization Act, which contains a wide variety of reforms that impact Medicare reimbursements to hospitalsservices and physicians including changes to Medicare payment methodologies for radiopharmaceuticals and other drugs dispensed by hospital

20

outpatient departments and for drugs dispensed by physician offices and independent diagnostic testing facilities. These changes reduced payment amounts for some of the drugs used in conjunction with our imaging procedures, although the physician fee schedule payment rates applicable to nuclear cardiology increased slightly. Downward changes to Medicare reimbursement rates may adversely impact reimbursement to customers or potential customers that use or could use our cameras and services. We cannot predict the full impact that this new legislation will have nor whether new federal legislation will be enacted in the future. The potential for adoption of healthcare reform proposalsproduct enhancements based on technological innovation on a state-by-statetimely basis, could require us to develop state-specific marketing and sales approaches. In addition, we may experience pricing pressures in connection with the sale of our products and services due to additional legislative proposals or healthcare reform initiatives. Our results of operationsmay become obsolete over time and our businessrevenues, cash flow, profitability and competitive position may suffer. Our success will depend on several factors, including our ability to:

Even if we successfully innovate and develop new products, services and product enhancements, we may incur substantial costs in doing so, and our profitability may suffer.

If we do not successfully manage the development and launch of new products and services, our financial results could therefore be adversely affected by future healthcare reforms.affected.

 The impact

We may face risks associated with launching new products and services. If we encounter development or manufacturing challenges or discover errors during our product development cycle, the product launch dates of regulatory changes could have a negative impact on camera sales to and leases with hospitals desiring to use our camerasnew products and services in their outpatient facilities.may be delayed. The expenses or losses associated with unsuccessful product development or launch activities or lack of market acceptance of our new products and services could adversely affect our business or financial condition.

 In order for hospitals to receive certain payments for their outpatient facilities as hospital outpatient services, including services that utilize

Undetected errors or defects in our products these services must be furnished in a "provider- based" organizationcould harm our reputation or facilitydecrease market acceptance of our products.

Our products may contain undetected errors or be covered services furnished "under arrangement"defects when first introduced or as new versions or new products are released. Disruptions affecting the introduction or release of, or other performance problems with, the hospital. Failure to meet these requirements may result in reduced payments to the hospitals for their services. The Medicare program has published and revised rules establishing criteria for classifying a facility as "provider-based" or a service as furnished "under arrangement." These rates require an analysis of the facts and circumstances surrounding the delivery by a hospital of a particular service, and hospitals that use our products may damage our customers’ businesses and could harm their and our reputation. If that occurs, we may incur significant costs, the attention of our key personnel could be diverted, or DIS servicesother significant customer relations problems may arise. We may also be subject to warranty and liability claims for damages related to errors or defects in their outpatient facilities will needour products. In addition, if we do not meet industry or quality standards, if applicable, our products may be subject to determine if they meet the applicable "provider-based"recall. A material liability claim, recall, or "under arrangement" requirements. Hospitalsother occurrence that cannot obtain sufficient payments for these services may not purchase a camera from usharms our reputation or enter into arrangements with us for provisiondecreases market acceptance of services.

The application of state certificate of need regulationsour products could harm our business and financial results.

        Some states currently require, or may require in the future, a certificate of need or similar regulatory approval prior to the acquisition of high-cost capital items, including diagnostic imaging systems, or provision of diagnostic imaging services by us or our clients. In many cases, a limited number of these certificates are available in a given state. If we or our clients are unable to obtain the applicable certificate or approval or additional certificates or approvals necessary to expand our operations, these regulations may limit or preclude our operations in the relevant jurisdictions.

If we fail to comply with various licensure, or certification standards, we may be subject to loss of licensure or certification, which would adversely affect our operations.

        All of the states in which we operate require that the imaging technicians that operate our cameras be licensed or certified. Obtaining such licenses may take significant time as we expand into additional states. Further, we are currently enrolled by Medicare contractors, or "carriers," as an independent diagnostic testing facility, or IDTF, in nine states and are seeking such enrollment by Medicare contractors in one additional state. Enrollment is essential for us to receive payment for healthcare services directly from Medicare. There can be no assurances we will be able to maintain such enrollment or that we will be able to gain such enrollment in other states. Any lapse in our licenses or enrollment, or the licensure or certification of our technicians, could increase our costs and adversely affect our operations and financialoperating results.

 In the healthcare industry, various types of organizations are accredited to facilitate meeting certain Medicare certification requirements, expedite third-party payment and fulfill state licensure requirements. Some managed care providers prefer to contract with accredited organizations. Thus far, we have not found it necessary to seek or obtain accreditation from any established accreditation agency. If it becomes necessary for us to do so in the future in order to satisfy the requirements of third-party payors or

21

regulatory agencies, there can be no assurances that we will be able to obtain or continuously maintain this accreditation.

Audits or denials of our claims, or claims submitted by our DIS customers, by government agencies or contractors could reduce our revenues or profits and expose us to claims.

        Under our "mixed bill" model, we submit claims directly to and receive payments directly from the Medicare program. Therefore, we are subject to extensive government regulation, including requirements for maintaining certain documentation to support our claims. Government agencies and Medicare contractors also may conduct inspections or surveys of our facilities, payment reviews and other audits of our claims and operations. For example, as part of a national audit conducted pursuant to the 2003 work plan, the Office of the Inspector General of the U.S. Department of Health and Human Services, or the OIG, conducted a review of one of our IDTF facilities in early 2003 to review the appropriateness of Medicare payments received. This audit was concluded without any action being taken by the OIG. While we believe this audit will have no impact on us, we cannot assure you that the OIG may not take some follow-up action. We may be subject to investigations, payment reviews and audits and cannot assure you that such scrutiny will not result in material delays in payment, as well as material recoupments or denials, which could reduce our revenue or profits. Our DIS customers also submit claims to Medicare and other third-party payors, are subject to the same types of regulation and scrutiny, and may experience the same types of problems. This could adversely affect our ability to market our leases and services and to maintain existing contracts.

Risks Related to Our Intellectual Property and Potential Litigation

Our ability to protect our intellectual property and proprietary technology through patents and other means is uncertain.

 Our success depends significantly on our ability to protect our proprietary rights to the technologies used in our products.

We rely on patent protection as well as a combination oftrademark, copyright, trade secret and trademark laws,other intellectual property rights protection and nondisclosure, confidentiality and other contractual restrictions to protect our proprietary technology. However, these legal means afford onlytechnologies, all of which provide limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage. Our success depends, in part, on our ability to protect our proprietary rights to the technologies used in our products. If we fail to protect and/or maintain our intellectual property, third parties may be able to compete more effectively against us, we may lose our technological or competitive advantage, and/or we may incur substantial litigation costs in our attempts to recover or restrict use of our intellectual property.

We do not have any pending U.S.patent applications. We cannot assure investors that we will continue to innovate and foreignfile new patent applications, or that if filed any future patent applications will result in granted patents. Further, we cannot predict how long it will take for such patents to issue, if at all. It is possible that, for any of our patents that have issued or that may issue in the future, our competitors may design their products around our patented technologies. Further, we cannot assure investors that other parties will not challenge any patents granted to us, or that courts or regulatory agencies will hold our patents to be valid, enforceable, and/or infringed. We cannot guarantee investors that we will be successful in defending challenges made against our patents and patent applications. Any successful third-party challenge or challenges to our patents could result in the unenforceability or invalidity of such patents, or such patents being interpreted narrowly and/or in a manner adverse to our interests. Our ability to establish or maintain a technological or competitive advantage over our competitors and/or market entrants may be diminished because of these uncertainties. For these and other reasons, our intellectual property may not provide us with any competitive advantage. For example:

To the extent our intellectual property offers inadequate protection, or is found to be invalid or unenforceable, we would be exposed to a greater risk of direct or indirect competition. If our intellectual property does not provide adequate coverage of our competitors’ products, our competitive position could be adversely affected, as could our business.

The measures that we use to protect the security of our intellectual property and other proprietary rights may not be adequate, which include claimscould result in the loss of legal protection for, and thereby diminish the value of, such intellectual property and other rights.

In addition to material aspectspursuing patents on our technology, we also rely upon trademarks, trade secrets, copyrights and unfair competition laws, as well as license agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented or misappropriated. In addition, we take steps to protect our intellectual property and proprietary technology by entering into confidentiality agreements and intellectual property assignment agreements with our employees, consultants, corporate partners and, when needed, our advisors. Such agreements may not be enforceable or may not provide meaningful protection for our trade secrets and/or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements, and we may not be able to prevent such unauthorized disclosure. Moreover, if a party having an agreement with us has an overlapping or conflicting obligation to a third party, our rights in and to certain intellectual property could be undermined. Monitoring unauthorized and inadvertent disclosure is difficult, and we do not know whether the steps we have taken to prevent such disclosure are, or will be, adequate. If we were to enforce a claim that a third party had illegally obtained and was using our trade secrets, it would be expensive and time consuming, the outcome would be unpredictable, and any remedy may be inadequate.

In addition, competitors could purchase our products and proceduresattempt to replicate and/or improve some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, design their products around our protected technology or develop their own competitive technologies that fall outside of our intellectual property rights. If our intellectual property does not adequately protect our market share against competitors’ products and methods, our competitive position could be adversely affected, as could our business.

We may need to enter into license agreements in the future.

We may need or may choose to obtain licenses and/or acquire intellectual property rights from third parties to advance our research or commercialization of our current or future products, and we cannot provide any assurances that third-party patents do not exist that might be enforced against our current or future products in the absence of such a license. We may fail to obtain any of these licenses or intellectual property rights on commercially reasonable terms. Even if we are not currently protected byable to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In that event, we may be required to expend significant time and resources to develop or license replacement technology. If we are unable to do so, we may be unable to develop or commercialize the affected products, which could materially harm our business and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation.

If we are sued for infringing intellectual property rights of third parties, it would be costly and time consuming, and an unfavorable outcome in that litigation could have a material adverse effect on our business.

Our success also depends on our ability to develop, manufacture, market and sell our products and perform our services without infringing the proprietary rights of third parties. Numerous U.S. issued patents and pending patent applications owned by third parties exist in the fields in which we are developing products and services. As part of a business strategy to impede our successful commercialization and entry into new markets, competitors may allege that our products and/or services infringe their intellectual property rights.

We could incur substantial costs and divert the attention of our management and technical personnel in defending ourselves against claims of infringement made by third parties. Any adverse ruling by a court or administrative body, or perception of an adverse ruling, may have a material adverse impact on our ability to conduct our business and our finances. Moreover, third parties making claims against us may be able to obtain injunctive relief against us, which could block our ability to offer one or more products or services and could result in a substantial award of damages against us. Intellectual property litigation can be very expensive, and we may not have the financial means to defend ourselves.

Because patent applications can take many years to issue, asthere may be pending applications, some of which are unknown to us, that may result in issued patents upon which our products or proprietary technologies may infringe. Moreover, we may fail to identify issued patents of relevance or incorrectly conclude that an issued patent is invalid or not infringed by our technology or any of our products. If a third-party claims that we infringe upon a third-party’s intellectual property rights, we may have to:

Our issued patents could be found invalid or unenforceable if challenged in court or at the Patent Office or other administrative agency, which could have a form that will be advantageous to us. material adverse impact on our business.

Any patents we have obtained or do obtain may be challenged by re-examination or otherwise invalidated.invalidated or eventually found unenforceable. Both the patent application process and the process of managing patent disputes can be time consuming and expensive. If we were to initiate legal proceedings against a third party to enforce a patent related to one of our products or services, the defendant in such litigation could counterclaim that our patent is invalid and/or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity and/or unenforceability are commonplace, as are validity challenges by the defendant against the subject patent or other patents before the USPTO. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement, failure to meet the written description requirement, indefiniteness, and/or failure to claim patent eligible subject matter. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent intentionally withheld material information from the USPTO, or made a misleading statement, during prosecution. Additional grounds for an unenforceability assertion include an allegation of misuse or anticompetitive use of patent rights, and an allegation of incorrect inventorship with deceptive intent. Third parties may also raise similar claims before the USPTO even outside the context of litigation. The outcome is unpredictable following legal assertions of invalidity and unenforceability. With respect to the validity question, for example, we cannot be certain that no invalidating prior art existed of which we and the patent examiner were unaware during prosecution. These assertions may also be based on information known to us or the Patent Office. If a defendant or third party were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the claims of the challenged patent. Such a loss of patent protection would or could have a material adverse impact on our business.

We may be involved in lawsuits to protect or enforce our patents, which could be expensive, time-consuming and unsuccessful.

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 that have issued or that may issue in the future, or develop products with functionalities that are comparable to ours. Although we have taken steps to protect our intellectual property and proprietary technology, including entering into confidentiality agreements and intellectual property assignment agreements with our employees, consultants, advisors and corporate partners, such agreements may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements. Furthermore, the laws of some foreign countries may not protect our intellectual property rights to the same extent as do the laws of the United States.

In the event a competitor infringes upon our patent or other intellectual property rights, litigation to enforce our intellectual property rights or to defend our patents against challenge, even if successful, could be expensive and time consuming and could require significant time and attention from our management. We may not have sufficient resources to enforce our intellectual property rights or to defend our patents against challenges from others.

 We have entered into

An adverse result in any such litigation proceedings could put one or more of our patents at risk of being invalidated, being found to be unenforceable, and/or being interpreted narrowly and could impact the validity or enforceability positions of our other patents. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a royalty-bearing license for one U.S. patent with a third-party for use in nuclear imaging, which license is co-exclusive with the U.S. government. We do not believerisk that some of our current

products implement the licensed patent; however, the licensor does not agree. We are currently negotiating to amend the license to resolve our dispute with the licensor. If we were to terminate the license, the licensor or subsequent licensee may allege that our current product infringes the patent, or such third-party licensee may develop and commercialize a competitive photodiode for use in gamma cameras.

The medical device industry is characterized by patent litigation and we could become subject to litigation thatconfidential information could be costly, resultcompromised by disclosure during this type of litigation. In addition, an adverse outcome in the diversionsuch litigation or proceedings may expose us to loss of our management's time and efforts, andproprietary position, expose us to significant liabilities, or require us to pay damages.

        The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Whether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assertseek licenses that our products, their components or the methods we employ in the use of our products are covered by U.S. or foreign patents held by them. In addition, they may claim that their patents have priority over ours because their patents were filed or invented earlier. Because patent applications can take many years to issue, there may be applications now pending of which we are unaware, which may later result in issued patents that our products may infringe. There could also be existing patents that one or more components of our products may be infringing of which we are unaware. As the number of participants in our industry increases, the possibility of patent infringement claims against us also increases.

        Any litigation or claims against us 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. If the relevant patents were upheld as valid and enforceable and we were found to be inadvertently infringing, we could be required to pay substantial damages and/or royalties and could be prevented from selling our products unless we could obtain a license or were able to redesign our system to avoid infringement. Any such license may not be available on reasonablecommercially acceptable terms, if at all.

We may make financial investments 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.

Our mobile healthcare fleet is highly utilized; any downtime in our assets could have a material impact on our revenues and costs.

Our Mobile Healthcare business unit utilizes a fleet of highly sophisticated imaging and related transportation assets that require nearly 100% uptime to service our customer needs. Though we utilize an array of highly competent service providers to support our imaging fleet, imaging and related transportation machines can experience unproductive downtime. Any downtime of our imaging fleet could have near term impacts on our revenues and underlying costs.

Our goodwill and other long-lived assets are subject to potential impairment that could negatively impact our earnings.

A significant portion of our assets consists of goodwill and other long-lived assets, the carrying value of which may be reduced if we determine that those assets are impaired. At March 31, 2020, goodwill and net intangible assets represented $32.1 million, or 38.3% of our total assets. In addition, net property, plant and equipment assets totaled $20.8 million, or 24.8% of our total assets. If actual results differ from the assumptions and estimates used in our goodwill and long-lived asset valuation calculations, we could incur impairment charges, which could negatively impact our earnings.

We review our reporting units for potential goodwill impairment annually or more often if events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In addition, we test the recoverability of long-lived assets if events or circumstances indicate the carrying values may not be recoverable. Recoverability of long-lived assets is measured by comparison of their carrying amounts to future undiscounted cash flows the assets are expected to generate. We conduct impairment testing based on our current business strategy in light of present industry and economic conditions, as well as future expectations. There are numerous risks that may cause the fair value of a reporting unit to fall below its carrying amount and/or the value of long-lived assets to not be recoverable, which could lead to the measurement and recognition of goodwill and/or long-lived asset impairment. These risks include, but are not limited to, significant negative variances between actual and expected financial results, lowered expectations of future financial results, failure to realize anticipated synergies from acquisitions, adverse changes in the business climate, and the loss of key personnel. If we failare not able to obtain any required licenses or make any necessary changesachieve projected performance levels, future impairments could be possible, which could negatively impact our earnings.

During the year ended December 31, 2018, the Company derecognized $1.1 million of goodwill related to the termination of the Philips Agreements with DMS Health effective December 31, 2017. Additionally, during the same period, the Company recorded a $0.5 million and $0.2 million goodwill impairment loss, respectively, related to Telerhythmics LLC (Telerhythmics), the Company’s cardiac event monitoring services business that was acquired on March 13, 2014. On October 31, 2018, the Company entered into a membership interest purchase agreement (the “Telerhythmics Purchase Agreement”) with G Medical Innovations USA, Inc. (“G Medical”), pursuant to which we sold all the outstanding membership interests in Telerhythmics to G Medical. On September 10, 2019, Digirad completed its acquisition of ATRM pursuant to the ATRM Merger Agreement. The $8.2 million goodwill recognized is attributable primarily to expected synergies and the assembled workforce of ATRM. As of December 31, 2019, as a result of the finalization of the purchase price allocation for the ATRM Merger, an adjustment of $3,000 was made to the recognized amounts of goodwill resulting from the acquisition of ATRM.

No other significant impairment losses on long-lived assets were recognized during the three months ended March 31, 2020 and 2019. See Note 1.Basis of Presentationand Note 4.Merger within the notes to our unaudited condensed consolidated financial statements included in our Quarterly Report on Form 10-Q for the three months ended March 31, 2020 and incorporated herein by reference for further discussion regarding goodwill and long-lived assets.

The Company is dependent on its senior management team and other key employees.

The Company’s success depends, to a significant extent, on its senior management team and other key employees and the ability of other personnel or new hires to effectively replace key employees who may retire or resign. Failure to retain its leadership team and attract and retain new leadership and other important personnel could lead to ineffective management and operations, which could materially and adversely affect its business and operating results.

ATRM’s operating results could be adversely affected by changes in the cost and availability of raw materials.

Prices and availability of raw materials used to manufacture its products or technologies, wecan change significantly due to fluctuations in supply and demand. Additionally, availability of the raw materials used to manufacture its products may be limited at times resulting in higher prices and/or the need to find alternative suppliers. Both KBS’s and EBGL’s major material components are dimensional lumber and wood sheet products, which include plywood and oriented strand board. Lumber costs are subject to market fluctuations. Furthermore, the cost of raw materials may also be influenced by transportation costs. It is not certain that any price increases can be passed on to its customers without affecting demand or that limited availability of materials will not impact its production capabilities. The state of the financial and housing markets may also impact its suppliers and affect the availability or pricing of materials. ATRM’s inability to raise the price of its products in response to increases in prices of raw materials or to maintain a proper supply of raw materials could have an adverse effect on its revenue and earnings.

If we are unable to commercialize one or more of our products.

We rely significantly on a license agreement with Segami Corporationsecure contracts for the imaging acquisitionKBS Projects or are unable to successfully complete the KBS Projects, our revenues and processing softwareresults could be adversely affected.

We are in advanced stages of negotiation for contracts to secure the KBS Projects; however, we can provide no assurance that we will be awarded the KBS Projects, that we will be able to successfully complete the KBS Projects if they are awarded to KBS, or that the anticipated revenues from the KBS Projects will be achieved. If we are not awarded the contracts for the KBS Projects, do not complete them as planned or do not receive payment for the KBS Projects as projected, then KBS’ and our digital gamma camera,revenues and results may be adversely affected.

If KBS is unable to maintain or establish its relationships with independent dealers and contractors who sell its homes, KBS revenue could decline.

KBS sells residential homes through a network of independent dealers and contractors. As is common in the modular home industry, KBS’s independent dealers may also sell homes produced by competing manufacturers and can cancel their relationships with KBS on short notice. In addition, these dealers may not remain financially solvent, as they are subject to industry, economic, demographic and seasonal trends similar to those faced by KBS. If KBS is not able to maintain good relationships with its dealers and contractors or establish relationships with new solvent dealers or contractors, KBS’s revenue could decline.

Due to the nature of ATRM’s business, many of its expenses are fixed costs and if there are decreases in demand for its products, it may adversely affect its operating results.

Many of its expenses, particularly those relating to properties, capital equipment, and certain manufacturing overhead items, are fixed in the short term. Reduced demand for its products causes its fixed production costs to be allocated across reduced production volumes, which adversely affects its gross margins and profitability.

Certain actions taken in connection with reducing operating costs may have a negative impact on ATRM’s business.

In the event of a housing downturn and a decline in its revenues, ATRM may implement cost reduction actions such as temporary factory shutdowns, workforce reductions, pay freezes and reductions, and reductions in other expenditures. In doing so, ATRM will attempt to maintain the necessary infrastructures to allow ATRM to take full advantage of subsequent improvements in market conditions. However, there can be no assurance that reductions ATRM may make in personnel and expenditure levels and the loss of the license could resultcapabilities of personnel ATRM has terminated or may terminate will not inhibit ATRM in delivery delays, lossthe timely ramp up of customers and loss of revenue.production in response to improving market conditions.

 Segami Corporation, or Segami, has developed image acquisition and processing software for our camera under a non-exclusive license agreement. In

Due to the event that Segami attempts to terminate the license agreement, refuses to extend the termnature of the license or seeks to impose unreasonable pricing or terms, we would have to find an alternative software system to use in our gamma camera. To our knowledge, there are a limited number of companies that would be able to developwork the Company and implement a software system similar to what we use in our gamma camera. As a result, inits subsidiaries perform, the event that we were unable to continue to use the software under the license from Segami, we could have delays in the production of our gamma camera as we attempted to find a substitute software provider. Furthermore, we cannot guarantee that alternative software providers would be able to meet our requirements or that their software would be available to us at favorable prices, if at all. To the extent we were unable to find an alternative source for the software, we may have to develop our own software system. We cannot guarantee that we could internally develop such a software system or that such efforts would not divert resources away from the development of other features of our camera. As a result, locating an alternative software system or developing our own software system could interrupt the manufacture and delivery of our products for an extended period of time and may cause the loss of customers and revenue.
