A Warning About Forward-Looking Statements
This Annual Report on Form 10-K contains forward-looking statements within the meaning of the federal securities laws that involve material risks, assumptions and uncertainties. Many possible events or factors could affect our future financial results and performance, such that our actual results and performance may differ materially from those that may be described or implied in the forward-looking statements. As such, no forward-looking statement can be guaranteed. Differences in actual results and performance may arise as a result of a number of factors including, without limitation, those discussed in this Annual Report on Form 10-K in Part I, Item 1A “Risk Factors.” Forward-looking statements typically are identified by the use of terms such as “may,” “will,” “should,” “might,” “expect,” “anticipate,” “estimate,” “plan,” “intend,” “goal,” “project,” “strategy,” “future,” and similar words, although some forward-looking statements are expressed differently. Forward-looking statements in this Annual Report include, among others, statements concerning: our outlook for the upcoming fiscal year regarding revenue growth, gross margins and earnings; the impact of the COVID-19 pandemic on our business, operations, strategy, liquidity and capital resources; projected capital expenditures for the upcoming fiscal year and our source of funds for such expenditures; the sufficiency of our liquidity and capital resources; that we may incur additional debt or issue additional equity; our strategy, goals, initiatives and objectives including, but not limited to, our entry into the over-the-counter market; anticipated new product offerings related to existing platforms; the anticipated beneficial attributes of products and platforms under development; anticipated new product and development results; our exposure to claims and litigation, including litigation currently pending against us involving Beckman Coulter; that we expect to continue to depend on a few key distributors for sales of our products; expected growth and the sources of that growth; the impact of new accounting standards; that point-of-care testing is increasing; that clinical reference laboratories will continue to be a competitive threat; that we will continue to make substantial expenditures for sales and marketing, manufacturing and product research and development activities; that integration costs will decline; industry consolidation and competition trends; competition for management and key personnel; the sufficiency of our facilities; the sufficiency of our insurance and our exposure to claims and litigation; our intention to not pay dividends; that we will continue to obtain licenses from third parties; and our intention to continue to evaluate technology and acquisition opportunities. The risks described under “Risk Factors” in Item 1A of this Annual Report and elsewhere herein and in reports and registration statements that we file with the Securities and Exchange Commission (the “SEC”) from time to time, should be carefully considered. You are cautioned not to place undue reliance on these forward-looking statements, which reflect management’s analysis only as of the date of this Annual Report. Except as required by law, we undertake no obligation to publicly release the results of any revision or update of these forward-looking statements, whether as a result of new information, future events or otherwise.

The Overall Market for In Vitro Diagnostics
Customers for In Vitro Diagnostics (“IVD”) products are primarily centralized laboratories and decentralized POC or alternate settings.
Centralized testing market
The centralized in vitro diagnostic testing process typically involves obtaining a specimen of blood, urine or other sample from the patient and sending the sample from the healthcare provider’s office, hospital unit or clinic to a central laboratory. In a typical visit to the physician’s office, after the patient’s test specimen is collected, the patient is usually sent home and receives the results of the test several hours or days later. The result of this process is that the patient may leave the physician’s office without confirmation of the diagnosis and the opportunity to begin potentially more effective immediate care.
Decentralized POC market
POC testing for certain diseases or conditions has become an accepted adjunct to central laboratory and self-testing. The professional POC market is comprised of two general segments: decentralized testing in non-institutional settings, such as physicians’ offices and institutional settings, such as hospitals (e.g., emergency rooms and bedside).
Out-of-hospital testing sites consist of physicians’ office laboratories, nursing homes, pharmacies, eye health offices, retail clinics and other non-institutional, ambulatory settings in which healthcare providers perform diagnostic tests.
Hospital POC testing is accepted and growing and is generally an extension of the hospital’s central laboratory. Hospitals in the U.S. have progressively sought to reduce the length of patient stays and, consequently, the
5



proportion of cases seen as outpatients has increased. If the U.S. experience is representative of future trends, emergency departments and other critical care units such as intensive care units, operating rooms, trauma and cardiac centers are increasingly becoming the principal centers for the management of moderate and severe acute illness.
The decentralized POC market utilizes a large variety of IVD products ranging from moderate-sized instrumented diagnostic systems serving larger group practices to single-use, disposable tests. We believe POC testing is increasing due to its clinical benefit, fast results, cost-effectiveness and patient satisfaction.
We believe that the growth in POC testing is in part due to evolving technological improvements creating high quality tests with laboratory accuracy and POC ease-of-use, some of which are capable of being granted a waiver under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”).
Over-the-counter market/Self-testing
There is an established market for self-testing that is available directly to consumers in the over-the-counter market in the U.S. and in other countries. In this market, users can purchase and administer tests directly at home and in many cases without a prescription or a visit to a physician. We have not historically sold our products into this market but plan to launch products through retail and over the counter channels in 2021.

Marketing and Distribution
Our current business strategy is designed around serving the continuum of healthcare delivery needs globally, starting with POC clinicians located in doctor’s office practices, to moderately complex POLs, through the highly complex environment in hospital and clinical reference laboratories in North America and a variety of settings internationally.
Within the inherent operational diversity of these various segments, we focus on ensuring market leadership and providing points of differentiation by specializing in the diagnosis and monitoring of selected disease states and conditions. Our marketing strategy includes ensuring that our key product portfolios are supported by clinical validation and health economic and outcomes research that demonstrates to hospitals, laboratories, acute care facilities and POC clinicians that our tests deliver fast, high quality results, are cost-effective to use, and improve patient outcomes.
Our North America distribution strategy takes into account the fact that the POC market is highly fragmented, with many small or medium-sized customers. A network of national and regional distributors is employed, as well as our own sales force, to reach customers using POC diagnostic tests.
We have expanded the size of our North America sales force in the past few years. As of December 31, 2020, we employed approximately 120 sales representatives in North America. This sales force works closely with our key distributors to drive market penetration of our products in the POC market.
The sales, distribution and service of our cell culture tests are controlled primarily by us. Laboratory end-users in hospitals and clinical reference laboratories using these diagnostic tests are reached through our own direct sales force and technical support services that have specialized training and understanding of the product portfolio.
We sell products globally and market and distribute products in a variety of ways, including a mix of direct and distribution strategies worldwide. In Europe, we currently employ approximately 85 employees to support sales and marketing activities in key countries, such as Germany and Italy. In addition, we have created a shared service center in Galway, Ireland to support general and administrative, technical support and customer service functions in Europe. In Asia, we currently employ approximately 50 employees in China and approximately 20 employees in India, primarily to support sales and marketing efforts for the Triage and BNP Businesses and to grow our core immunoassay and cell culture businesses. In addition, we have created a shared service center in Shanghai, China to support general and administrative and technical support and customer service functions in China.
We derive a significant portion of our total revenue from a few distributors. Four of our distributors, which are considered to be among the market leaders, collectively accounted for approximately 68%, 51% and 49% of our total revenue for the years ended December 31, 2020, 2019 and 2018, respectively. See Note 9 in the Consolidated Financial Statements included in this Annual Report.

13485:2016 and MDSAP medical device standards. Packaging, warehousing and shipping logistics with cold chain storage capability are handled at the facility.
Our Summers Ridge, San Diego, California facility consists of laboratories that are involved in mammalian cell culture, bacterial fermentation, protein purification and modification, as well as other techniques involved in immunoassay reagent manufacturing. These reagents are used in the manufacture of devices made at the site and are also supplied to a third party as key active ingredients for our BNP product that is run on the Beckman Coulter Immunoassay Systems. In addition, this site has production areas dedicated to creating and processing plastic components that are subsequently transformed into finished devices (Cardiac and Drugs of Abuse products) using customized manufacturing equipment, including specialized automation. This facility is certified to the EN ISO 13485:2016 and MDSAP medical device standards. Most of the products are packaged and subsequently distributed out of the facility.
We seek to conduct our manufacturing in compliance with regulations that comply to U.S., Australia, Brazil, Canada, Japan, Europe, South Korea and other countries Quality Management System (“QSR”) requirements. Our manufacturing facilities have passed routine regulatory inspections confirming compliance with the QSR regulatory requirements. Our facilities are registered with various regulatory bodies including the FDA and the Department of Health Services of the State of California for our San Diego facilities.
Government Regulation
Regulation in the United States
The testing, manufacture and commercialization of our products are subject to regulation by numerous governmental authorities, principally the FDA and corresponding state and foreign regulatory agencies. Pursuant to the U.S. Federal Food, Drug, and Cosmetic Act and the regulations promulgated thereunder, the FDA regulates the preclinical and clinical testing, manufacture, labeling, distribution and promotion of medical devices. Noncompliance with applicable requirements can result in, among other matters, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the FDA to grant premarket clearance or premarket approval for devices, withdrawal of marketing clearances or approvals and criminal prosecution. The FDA also has the authority to request a recall, repair, replacement or refund of the cost of any device manufactured or distributed in the U.S. if the device is deemed to be unsafe.
In the U.S., devices are classified into one of three classes (Class I, II or III) on the basis of the controls deemed necessary by the FDA to reasonably ensure their safety and effectiveness. Class I and II devices are subject to general controls including, but not limited to, performance standards, premarket notification (“510(k)”) and post market surveillance. Class III devices generally pose the highest risk to the patient and are typically subject to premarket approval to ensure their safety and effectiveness. Our current products are all Class I or II.
The FDA can authorize the emergency use of an unapproved medical product or an unapproved use of an approved medical product, referred to as Emergency Use Authorization, or EUA, for certain emergency circumstances after the Health and Human Services Secretary has made a declaration of emergency justifying authorization of emergency use. An EUA allows use in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions caused by emerging infectious disease threats when there are no adequate, approved, and available alternatives. The FDA may also waive otherwise-applicable current good manufacturing practice (CGMP) requirements to accommodate emergency response needs. All of our current products for testing for the COVID-19 virus are sold under EUA.
Prior to commercialization in the U.S. market, manufacturers of diagnostic assays like our products are typically required to obtain FDA clearance through a premarket notification or premarket approval process, which can be lengthy, expensive and uncertain. The FDA has been requiring more rigorous demonstration of product performance as part of the 510(k) process, including submission of extensive clinical data. It generally takes from three months to one year to obtain clearance but may take longer. A premarket approval application must be supported by valid scientific evidence to demonstrate the safety and effectiveness of the device, typically including the results of clinical investigations, bench tests and reference laboratory studies. In addition, modifications or enhancements for existing products that could significantly affect safety, effectiveness or constitute a major change in the intended use of the device, will require new submissions to the FDA.
CLIA regulates laboratory testing and require clinical laboratories to be certified by their state as well as the Center for Medicare and Medicaid Services (CMS) before diagnostic testing can be conducted. Labs using our assays must obtain a CLIA certificate. Waived testing is designated by CLIA as simple testing that carries a low risk for an incorrect result. The CLIA waived designation is critical for most of our products that are intended for POC settings. The FDA’s current guidance entitled “Guidance for Industry and FDA Staff: Recommendations for Clinical Laboratory Improvement Amendments of 1988 CLIA
13



Waiver Applications for Manufacturers of In Vitro Diagnostic Devices” sets forth requirements for obtaining a CLIA waiver that are onerous and have increased the time and cost required to obtain a CLIA waiver.
Any devices we manufacture or distribute pursuant to FDA clearance or approvals are subject to continuing regulation by the FDA and certain state agencies, including adherence to QSR relating to testing, control, documentation and other quality assurance requirements. We must also comply with Medical Device Reporting requirements mandating reporting to the FDA of any incident in which a device may have caused or contributed to a death or serious injury, or in which a device malfunctioned and, if the malfunction were to recur, would be likely to cause or contribute to a death or serious injury. Labeling and promotional activities are also subject to scrutiny by the FDA and, in certain circumstances, by the Federal Trade Commission. Current FDA enforcement policy prohibits the marketing of approved medical devices for unapproved uses.
Regulation Outside of the United States
For marketing outside the U.S., we are subject to foreign regulatory requirements governing human clinical testing and marketing approval for our products. These requirements vary by jurisdiction, differ from those in the U.S., and may require us to perform additional or different preclinical or clinical testing regardless of whether we have obtained FDA clearance or approval. The amount of time required to obtain necessary approvals may be longer or shorter than that required for FDA clearance or approval. In many foreign countries, pricing and reimbursement approvals are also required.
Our initial focus for obtaining marketing approval outside the U.S. is typically the European Union (EU), Japan, China, Brazil, Australia and Canada. EU regulations and directives generally classify healthcare products either as medicinal products, medical devices or in vitro diagnostics. The CE Mark certification for the EU requires us to receive certification for the manufacture of our products from ISO. This certification comes only after the development of an all-inclusive quality system, which is reviewed for compliance with ISO standards by a notified body accredited by an EU member state. After certification is received, a technical file is developed which attests to the product’s compliance to Regulation Directive 98/79/EC for in vitro diagnostic medical devices. Only after this point is the product CE marked. In addition, the EU has recently adopted the EU Medical Device Regulation (the "EU MDR") and the In Vitro Diagnostic Regulation (the "EU IVDR"), each of which impose stricter requirements for the marketing and sale of medical devices, including in the area of clinical evaluation requirements, quality systems and post-market surveillance. Manufacturers of currently approved medical devices will have until May 2021 to meet the requirements of the EU MDR and until May 2022 to meet the EU IVDR. Complying with the requirements of these regulations may require us to incur significant expenditures. Failure to meet these requirements could adversely impact our business in the EU and other regions that tie their product registrations to the EU requirements.
Chinese regulations require registration of diagnostic products with China’s National Medical Products Administration (NMPA, formerly CFDA). Additional clinical trials in China are typically required for registration purposes. ISO certification is included in applications for registration to NMPA. Japanese regulations require registration of in vitro diagnostic products with the Japanese Ministry of Health, Labor and Welfare. For products marketed in Canada, registration is required with Health Canada. For products marketed in Australia, registration is required with the Therapeutic Goods Administration. In vitro diagnostics in Brazil are regulated by the Agencia Nacional de Vigilancia Sanitaria (ANVISA). For our products marketed in Canada, Japan, Brazil, Australia and the United States, the MDSAP is a single regulatory audit of our quality management system that satisfies the requirements of all five of these jurisdictions. Additionally, with Brexit in place, we are obtaining any necessary approvals directly with the U.K.’s Medicines and Healthcare Products Regulatory Agency.
Intellectual Property
The healthcare industry has traditionally placed considerable importance on obtaining and maintaining patent and trade secret protection for commercially relevant technologies, devices, products and processes. We and other companies engaged in research and development of new diagnostic products actively seek to protect trade secrets and pursue patents for technologies that are considered novel and patentable. However, important factors, many of which are not within our control, can affect whether and to what extent patent protection in the U.S. and in other important markets worldwide is obtained. By way of example, the speed, accuracy and consistency in application of the law in a patent office within any particular jurisdiction is beyond our control and can be unpredictable. The resolution of issues such as these and their effect upon our long-term success is likewise indeterminable. We have issued patents, both in the U.S. and internationally, and have patent applications pending throughout the world.
It has been our policy to file for patent protection in the U.S. and other countries with significant markets, such as Western European countries and Japan, if the economics are deemed to justify such filing and our patent counsel advises that relevant patent protection may be obtained.
14



A large number of individuals and commercial enterprises seek patent protection for technologies, products and processes in fields in, or related to, our areas of product development. To the extent such efforts are successful, we may be required to obtain licenses and pay significant royalties in order to exploit certain of our product strategies. Licenses may not be available to us at all or, if so available, may not be available on acceptable terms.
We are aware of certain patents issued to various developers of diagnostic products with potential applicability to our diagnostic technology. We have licensed rights from companies to assist with the manufacturing of certain products. In the future, we expect that we will require or desire additional licenses from other parties in order to refine our products further and to allow us to develop, manufacture and market commercially viable or superior products effectively.
We seek to protect our trade secrets and technology by entering into confidentiality agreements with employees and third parties (such as potential licensees, customers, strategic partners and consultants). In addition, we have implemented certain security measures in our laboratories and offices. Also, to the extent that consultants or contracting parties apply technical or scientific information independently developed by them to our projects, disputes may arise as to the proprietary rights to such data.
Under many of our contractual agreements, we have agreed to indemnify the counterparty against costs and liabilities arising out of any patent infringement claims and other intellectual property claims asserted by a third party relating to products sold under those agreements.
Competition
Competition in the development and marketing of IVD products is intense, and innovation, product development, regulatory clearance to market and commercial introduction of new IVD technologies can occur rapidly. We believe that some of the most significant competitive factors in the rapid diagnostic market include convenience, speed to result, specimen flexibility, product menu, clinical needs, price, reimbursement levels and product performance as well as effective distribution, advertising, promotion and brand name recognition. The competitive factors in the central laboratory market are also significant and include price, product performance, reimbursement, compatibility with routine specimen procurement methods, and manufacturing products in testing formats that meet the workflow demands of larger volume laboratories. We believe our success will depend on our ability to remain abreast of technological advances, to develop, gain regulatory clearance and introduce technologically advanced products, to effectively market to customers a differentiated value proposition represented by our commercialized products, to maintain our brand strength and to attract and retain experienced personnel. The majority of diagnostic tests requested by physicians and other healthcare providers are performed by independent clinical reference laboratories. We expect that these laboratories will continue to compete vigorously to maintain their dominance of the testing market. In order to achieve market acceptance for our products, we will be required to continue to demonstrate that our products provide physicians and central laboratories cost-effective and time-saving alternatives to other competitive products and technologies.
Many of our current and prospective commercial competitors, including several large pharmaceutical and diversified healthcare companies, have substantially greater financial, marketing and other resources than we have. These competitors include, among others, Abbott Laboratories, Beckman Coulter Primary Care Diagnostics, Thermo Fisher Scientific, Becton Dickinson and Company, Meridian Bioscience, Inc., and Danaher Corporation. We also face competition from our distributors since some have created, and others may decide to create, their own products to compete with ours. Competition may also exist with large, medium and small development companies whose portfolio and technologies are dedicated to the development of diagnostic solutions in areas in which we currently have relevant market share.
Seasonality
Sales of our influenza products are subject to, and significantly affected by, the seasonal demands of the cold and flu seasons, prevalent during the fall and winter. As a result of these seasonal demands, we typically experience lower sales volume in the second and third quarters of the calendar year, and typically have higher sales in the first and fourth quarters of the calendar year. The COVID-19 pandemic and impact of sales of our COVID-19 products combined with a very mild flu season diminished the seasonal effects in 2020. Historically, sales of our influenza products have varied from year to year based in large part on the severity, length and timing of the onset of the cold and flu season. For the years ended December 31, 2020, 2019 and 2018, sales of our influenza products accounted for 8%, 26% and 24%, respectively, of total revenue. In addition, it is possible that the SARS-CoV-2 virus may have similar seasonal demands and impacts on our revenues in the future.

Human Capital Resources
As of December 31, 2020, we had approximately 1,370 employees worldwide, with approximately 1,200 employees in the United States and approximately 170 employees outside of the United States, none of whom are represented by a labor union. We have experienced no work stoppages and believe that our employee relations are good.
Our employees are one of our most important assets and set the foundation for our ability to achieve our strategic objectives, drive operational execution, deliver strong financial performance, advance innovation and maintain our quality and compliance programs.
The success and growth of our business depends in large part on our ability to attract, retain and develop a diverse population of talented and high-performing employees at all levels of our organization. To succeed in a competitive labor market, we have recruitment and retention strategies that we focus on as part of the overall management of our business, including designing our compensation and benefits programs to be competitive and align with our strategic and stockholders’ interests. Some of our key employee benefits include eligibility for health insurance, vacation time, a retirement plan with an employer match, an employee assistance program, life and disability coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their needs, including flexible spending accounts, hospital care, accident insurance, prepaid legal benefits, backup childcare, family forming benefits, homework support for students, student loan debt benefits, tuition reimbursement and a wellness program.

Item 1A. Risk Factors
Operational and Strategic Risks
The novel coronavirus global pandemic could adversely affect our business operations, financial performance and results of operations, the extent of which is uncertain and difficult to predict.
In late 2019, a novel strain of COVID-19 was identified, which has since spread globally and evolved into a global pandemic, including severe and widespread transmission in the United States and throughout the world. In response, government authorities throughout the United States and around the world have implemented numerous measures to try to reduce the spread of COVID-19, such as travel restrictions, quarantines, shelter in place or total lock-down orders and other business restrictions. As a result of the COVID-19 outbreak and the related responses from government authorities, our business operations, financial performance and results of operations may be adversely impacted in a number of ways, including, but not limited to, the following:
a slowdown or stoppage in the supply chain of the raw materials, components, equipment and packaging services used to manufacture our products or our inability to secure additional or alternate sources of supplies or services needed to manufacture our products at optimal levels;
our inventory might be requisitioned, diverted or allocated by government order such as under emergency, disaster and civil defense declarations. For example, government actions in response to the COVID-19 pandemic affect our supply allocation, and those and our own allocation decisions can impact our customer relationships;
interruptions or delays in global shipping to transport and deliver our products to our distributors and customers;
interruptions in normal operations of certain end use customers that could result in reductions in demand for non-COVID-19 related healthcare operations and testing;
disruptions to our operations, including a shutdown of one or more of our facilities or product lines; restrictions on our operations and sales, marketing and distribution efforts; and interruptions to our research and development, manufacturing, clinical/regulatory and other important business activities;
increased costs in our manufacturing, production and shipping processes;
limitations on employee resources and availability, including due to sickness or personal quarantine, government restrictions, the desire of employees to avoid contact with large groups of people, school closures or mass transit disruptions;
an increase in cyber-attacks given our increased public profile, particularly as a manufacturer of COVID-19 products;
a fluctuation in foreign currency exchange rates or interest rates could result from market uncertainties;
an increase in exposure to credit losses for customers adversely affected by the COVID-19 pandemic;
an increase in regulatory restrictions or continued market volatility could hinder our ability to execute strategic business activities, including acquisitions; and
an increase in the volatility of our stock price.
The spread of COVID-19 has caused us to modify our business practices (including employee travel, employee work locations, and physical participation in meetings, events and conferences), and we may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers, partners, and suppliers. Such measures may not mitigate fully the risks posed by the virus, impairing our ability to perform critical functions.
In response to increased demand brought on by COVID-19, we are continuing to rapidly and significantly expand our manufacturing capacity, including expanding and scaling our infrastructure to support existing and anticipated COVID-19 testing demand and commercial activities. This rapid expansion has placed and may continue to place significant strain on our management, personnel, operations, systems and financial resources. Failure to successfully manage this expansion could negatively affect our operating results, including due to inefficiencies in implementing such expansion or higher costs for materials, technology, equipment and human capital during the intensity of the COVID-19 pandemic. Moreover, we may not realize the revenue growth and profitability we anticipate for our COVID-19 and other diagnostic products, which could cause, among other results, a failure to realize the benefits of our manufacturing capacity expansion and the value of those investments being written down or written off.
Additionally, COVID-19 could negatively affect our internal controls over financial reporting as a portion of our workforce is required to work from home and therefore new processes, procedures, and controls could be required to respond to
18



changes in our business environment. Further, should any key employees become ill from COVID-19 and unable to work, the attention of the management team could be diverted.
The effects of COVID-19 may exacerbate our other risk factors described below. The degree to which COVID-19 impacts our business operations, financial performance and results of operations will depend on future developments, which are highly uncertain, continuously evolving and cannot be predicted, including, but not limited to, the duration of the COVID-19 outbreak, the severity of continual outbreak surges, the actions to contain the virus or treat its impact, how quickly and to what extent normal economic and operating conditions can resume and the residual economic and other effects. Because this situation continues to evolve globally, the ultimate impacts to us of COVID-19 are uncertain, but such impacts could have a material adverse effect on our business, financial performance and financial condition.
The industry and market segment in which we operate are highly competitive, and intense competition with other providers of diagnostic products or services may reduce our sales and margins.
Our diagnostic tests compete with similar products made by our competitors. There are a large number of multinational and regional competitors making investments in competing technologies and products, including several large pharmaceutical and diversified healthcare companies. We also face competition from our distributors as some have created, and others may decide to create, their own products to compete with ours. A number of our competitors have competitive advantages, such as substantially greater financial, technical, research and other resources, and larger, more established marketing, sales, distribution and service organizations than we have. Moreover, some competitors offer broader product lines and have greater name recognition than we have. Our operating results could be materially and adversely affected if:
our competitors’ products are more effective than ours or take market share from our products through more effective marketing or competitive pricing;
our competitors obtain patent protection or other intellectual property rights that prevent us from offering competing products or services; or
our competitors are able to obtain regulatory approvals for products or services or otherwise bring competing products to market earlier than us.
In addition, there has been a trend toward industry consolidation in our markets over the last few years. We may not be able to compete successfully in an increasingly consolidated industry. We expect this trend toward industry consolidation to continue as companies attempt to strengthen or hold their market positions in an evolving industry.
In order to remain competitive and profitable, we must expend considerable resources to research new technologies and products and develop new markets, and there is no assurance our efforts to develop new technologies, products or markets will be successful or such technologies, products or markets will be commercially viable.
We devote a significant amount of financial and other resources to researching and developing new technologies, new products and new markets. The development, manufacture and sale of diagnostic products and new technologies require a significant investment of resources, such as new employees, offices, manufacturing facilities, and development of new commercial partners and channels. Such expenditures to develop new technologies, products or markets may not lead to commercially viable technology and products or successful markets.
Our operations will be adversely affected if our operating results do not correspondingly increase with our increased expenditures or if our technology, product and market development efforts are unsuccessful or delayed. Furthermore, our failure to successfully introduce new technologies or products and develop new markets could have a material adverse effect on our business and prospects.
Our operating results are heavily dependent on sales of our COVID-19 and influenza diagnostic tests and if sales or revenues of our COVID-19 or influenza tests decline for any reason, our operating results would be materially and adversely affected.
A significant percentage of our total revenues come from a limited number of our product families. In particular, revenues from the sale of our COVID-19 and influenza tests represent a significant portion of our total revenues and are expected to remain so for at least the near future. For the years ended December 31, 2020, 2019 and 2018, sales of our COVID-19 products accounted for 70%, 0% and 0% and influenza products accounted for 8%, 26%, and 24%, respectively, of total revenue. In addition, the gross margins derived from sales of our COVID-19 and influenza tests are significantly higher than the gross margins from many of our other core products. As a result, if sales or revenues of our COVID-19 or influenza tests decline for any reason whether as a result of an end to the COVID-19 pandemic, a mild flu season, market share loss or price pressure,
19



obsolescence, regulatory matters, such as loss of EUAs for our COVID-19 products, or any other reason, our operating results would be materially and adversely affected on a disproportionate basis.
We rely on a limited number of key distributors that account for a significant portion of our total revenue. The loss of any key distributor or an unsuccessful effort by us to directly distribute our products could lead to reduced sales.
Although we have many distributor relationships in the U.S., the market is dominated by a small number of these distributors. Four of our U.S. distributors, collectively accounted (each individually in excess of 10%) for approximately 68%, 51%, and 49% of our total revenue for the years ended December 31, 2020, 2019 and 2018, respectively. In addition, we rely on a few key distributors for a majority of our international sales and expect to continue to do so for the foreseeable future. The loss or termination of our relationship with any of these key distributors could significantly disrupt our business unless suitable alternatives are timely found or lost sales to a distributor are absorbed by another distributor. Finding a suitable alternative to a lost or terminated distributor may pose challenges in our industry’s competitive environment, and another suitable distributor may not be found on satisfactory terms, if at all. For instance, some distributors already have exclusive arrangements with our competitors, and others do not have the same level of penetration into our target markets as our existing distributors. If total revenue from any of our other significant distributors were to decrease in any material amount in the future or we are not successful in timely transitioning business from a lost or terminated distributor to one or more new distributors, our business, operating results and financial condition could be materially and adversely affected.
Our results of operations and financial condition may be adversely affected by the financial soundness of our customers and suppliers.
If our customers’ or suppliers’ operating and financial performance deteriorates, our customers may not be able to pay, or may delay payment of, accounts receivable owed to us, and our suppliers may restrict credit to us or impose different payment terms or reduce or terminate production of products they supply to us. Any inability of customers to pay us, or any demands by suppliers for different payment terms, may adversely affect our operating results and financial condition.
We may not achieve market acceptance of our products among physicians, healthcare providers or other customers, and this would have a negative effect on future sales.
A large part of our current business is based on the sale of rapid POC diagnostic tests. Our future sales depend on, among other matters, capture of sales from central laboratories by achieving market acceptance of POC testing from physicians other healthcare providers or other customers. If we do not capture sales at the levels anticipated in our budget, our total revenue will not be at the levels that we expect and the costs we incur or have incurred may be disproportionate to our sales levels. We expect that clinical reference and hospital-based laboratories will continue to compete vigorously against our POC diagnostic products in order to maintain and expand their existing dominance of the overall diagnostic testing market. Moreover, even if we can demonstrate that our products are more cost-effective, save time, or have better performance, physicians and other healthcare providers may resist changing to POC tests. Our failure to achieve market acceptance from physicians, healthcare providers or other customers with respect to the use of our diagnostic products would have a negative effect on our future sales.
Our total revenue could be affected by third-party reimbursement policies and potential cost constraints.
The end-users of our POC products are primarily physicians and other healthcare providers. In the U.S., healthcare providers such as hospitals and physicians who purchase diagnostic products generally rely on third-party payers, principally private health insurance plans, federal Medicare and state Medicaid, to reimburse all or part of the cost of the procedure. Use of our products would be adversely impacted if physicians and other healthcare providers do not receive adequate reimbursement for the cost of our products by their patients’ third-party payers. Our total revenue could also be adversely affected by changes or trends in reimbursement policies of these governmental or private healthcare payers. We believe that the overall escalating cost of medical products and services has led to, and will continue to lead to, increased pressures on the healthcare industry, both foreign and domestic, to reduce the cost of products and services. Given the efforts to control and reduce healthcare costs in the U.S. in recent years, currently available levels of reimbursement may not continue to be available in the future for our existing products or products under development. Third-party reimbursement and coverage may not be available or adequate in either the U.S. or foreign markets, current reimbursement amounts may be decreased in the future and future legislation, regulation or reimbursement policies of third-party payers may reduce the demand for our products or adversely impact our ability to sell our products on a profitable basis. Any reduction in payments by government sponsored or private payers, as a result of budget deficits or reductions in expenditures or for reimbursement reasons, may adversely affect our earnings and cash flow.
20



Unexpected increases in, or inability to meet, demand for our products and services could require us to spend considerable resources to meet the demand or harm our reputation and customer relationships if we are unable to meet demand.
Our inability to meet customer demand for our products and services, whether as a result of manufacturing problems or supply shortfalls, could harm our customer relationships and impair our reputation within the industry. In addition, our product manufacturing of certain product lines is concentrated in one or more of our manufacturing sites. Weather, natural disasters, public health emergencies, fires, terrorism, political change or unrest, failure to follow specific internal protocols and procedures, equipment malfunction, environmental factors or damage to one or more of our facilities could adversely affect our ability to manufacture our products. This, in turn, could have a material adverse effect on our business.
If we experience unexpected increases in the demand for our products or supply shortfalls, we may be required to expend additional capital resources to meet these demands. These capital resources could involve the cost of new machinery or even the cost of new manufacturing facilities. This would increase our capital costs, which could adversely affect our earnings and cash resources. If we are unable to develop or obtain necessary manufacturing capabilities in a timely manner, our total revenue could be adversely affected. For example, in response to the demand brought on by COVID-19, we have and are continuing to rapidly and significantly expand our manufacturing capacity, which has placed and may continue to place significant strain on our management, personnel, operations and systems. Failure to increase production volumes in a cost-effective manner, lower than anticipated yields or production problems could result in shipment delays as well as increased manufacturing costs, which could also have a material adverse effect on our business, reputation, operating results and financial condition.
Interruptions in the supply of raw materials, components, equipment and other products and services could adversely affect our operations and financial results.
We depend on third-party manufacturers and suppliers for some of our materials, components, equipment, packaging and other products and services. Some of these supplies and services are currently obtained from a sole supplier or a limited group of suppliers. We have long-term supply agreements with many of these suppliers, but these long-term agreements involve risks for us, such as our potential inability to obtain an adequate supply of quality raw materials, equipment or components and our reduced control over pricing, quality and timely delivery. It is also possible that one or more of these suppliers may become unwilling or unable to deliver supplies or services to us as agreed. Unexpected increases in demand for our products or supply shortfalls could require us to obtain additional supplies or services in order to manufacture products to meet the demand. Some supplies require significant ordering lead time and we may not be able to timely access sufficient supplies in the event of an unexpected increase in demand or supply shortfall, particularly those obtained from a sole supplier or a limited group of suppliers. For example, government actions in response to the COVID-19 pandemic have affected our supply allocation and could in the future result in our inventory materials being requisitioned, diverted or allocated by government order such as under emergency, disaster and civil defense declarations. In addition, we use third party packaging companies to ship our products to customers. An interruption or delays in the services provided by these third-party packaging companies could also result in a delay of shipments to customers.
Our business is also subject to risks associated with U.S. and foreign legislation, regulations and trade agreements relating to the materials we import, including quotas, duties, tariffs or taxes, and other charges or restrictions on imports, which could adversely affect our operations and our ability to import materials used in our products at current or increased levels. We cannot predict whether additional U.S. and foreign customs quotas, duties (including antidumping or countervailing duties), tariffs, taxes or other charges or restrictions, requirements as to where raw materials must be purchased, or other restrictions on our imports will be imposed in the future or adversely modified, or what effect such actions would have on our costs of operations. Future quotas, duties or tariffs may have a material adverse effect on our business, financial condition, results of operations or cash flows. Future trade agreements could also provide our competitors with an advantage over us, or increase our costs, either of which could have a material adverse effect on our business, financial condition, results of operations or cash flows.
In addition, due to regulatory requirements relating to the qualification of suppliers, we may not be able to establish additional or replacement sources on a timely basis or without excessive cost. For example, FDA regulations and labelling requirements may make switching critical supplies difficult. The SEC also requires disclosure for public companies whose products contain conflict minerals, such as tin, tantalum, tungsten and gold, that originate from the Democratic Republic of Congo and/or adjoining countries. The implementation of these requirements has caused and will continue to cause increased costs to comply with these disclosure requirements and may inhibit our ability to source these materials. Any shortfall in our supply of raw materials, equipment or components, or our inability to quickly and cost-effectively obtain alternative sources for this supply, could have a material adverse effect on our business and operating results.
21



Failures in our information technology and storage systems, including as a result of cyber-security breaches, could significantly disrupt our business or force us to expend excessive costs.
We utilize complex information technology systems to transmit and store information, including sensitive personal information and proprietary or confidential information, and otherwise to support our business and process. In the future, our systems my prove inadequate to our business needs and necessary upgrades may not operate as designed, which could result in excessive costs or disruptions in portions of our business. In particular, any disruptions, delays or deficiencies caused by our enterprise resource planning systems could adversely affect our ability to, among other matters, process orders, procure supplies, manufacture and ship products, track inventory, provide services and customer support, send invoices and track payments, fulfill contractual obligations or otherwise operate our business.
Our servers are potentially vulnerable to physical or electronic break-ins, ransomware attacks, computer viruses and similar disruptive problems. Sustained or repeated system failures that interrupt our ability to generate, maintain or access data could result in a material disruption in our operations. Furthermore, a security breach could be facilitated by ineffective protection measures, employee errors or omissions, and malfeasance. Despite our efforts to protect against cyber-attacks and security breaches, hackers and other cyber criminals are using increasingly sophisticated and constantly evolving techniques, and we may need to expend substantial additional resources to continue to protect against potential security breaches or to remediate problems caused by such attacks or any breach of our safeguards. In addition, a data security breach or ransomware attack could distract management or other key personnel from performing their primary operational duties. If such a breach leads to disclosure of consumer, customer, supplier, partner or employee information (including personally identifiable information or protected health information), it could harm our reputation, compel us to comply with disparate state and foreign breach notification laws and otherwise subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue.
Furthermore, foreign privacy laws impose significant obligations on U.S. companies to protect the personal information of foreign citizens. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our data practices, which could have a material adverse effect on our business. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business.
We face risks relating to our international sales, including inherent economic, political and regulatory risks, that could impact our financial performance, cause interruptions in our current business operations and impede our growth strategy.
Our products are sold internationally, with the majority of our international sales to our customers in Europe and Asia-Pacific. We currently sell and market our products through direct sales, distributor organizations and sales agents. Sales to foreign customers accounted for 13%, 33% and 32% of our total revenue for the years ended December 31, 2020, 2019 and 2018, respectively. Our international operations are subject to inherent economic, political and regulatory risks, which could impact our financial performance, cause interruptions in our business operations and impede our international growth. These foreign risks include, among others:
compliance with multiple different registration requirements and new and changing product registration requirements, our inability to benefit from registration for our products inasmuch as registrations may be controlled by a distributor, and the difficulty in transitioning our product registrations;
compliance with complex foreign and U.S. laws and regulations that apply to our international operations, including U.S. laws such as import/export limitations, the Foreign Corrupt Practices Act, and local laws prohibiting corrupt payments to governmental officials, could expose us or our employees to fines and criminal sanctions and damage our reputation;
tariffs or other barriers as we continue to expand into new countries and geographic regions;
exposure to currency exchange fluctuations against the U.S. dollar;
longer payment cycles, generally lower average selling prices and greater difficulty in accounts receivable collection and enforcing agreements with foreign entities;
reduced, or lack of, protection for, and enforcement of, intellectual property rights;
social, political and economic instability in some of the regions where we currently sell our products or that we may expand into in the future, including as a result of acts of terrorism, health pandemics, natural disasters and disruptions in global transportation;
increased financial accounting and reporting burdens and complexities;
complex and potentially adverse tax consequences; and
diversion to the U.S. of our products sold into international markets at lower prices.
22



Our international operations are governed by the U.S. Foreign Corrupt Practices Act and similar anti-corruption laws outside the U.S. Global enforcement of anti-corruption laws has increased substantially in recent years, with more enforcement proceedings by U.S. and foreign governmental agencies and the imposition of significant fines and penalties. While we have implemented policies and procedures designed to comply with these laws, our international operations, which may involve customer relationships with foreign governments, create the risk that there may be unauthorized payments or offers of payments made by employees, consultants, sales agents or distributors. Any alleged or actual violations of these laws may subject us to government investigations, significant criminal or civil sanctions and other liabilities, and negatively affect our reputation.
During the year ended December 31, 2020, we generated approximately $119.8 million in revenue denominated in currencies other than the U.S. dollar. The major currencies to which our revenues are exposed are the Euro and the Chinese Yuan. Fluctuations in the values of the Euro, the Chinese Yuan, and other foreign currencies could have a negative impact on our business, financial condition and results of operations.
Continuing worldwide political and social uncertainty, including tariffs, trade wars or social tensions, may adversely affect our business and prospects, both domestically and internationally.
Political and social uncertainty in the U.S. and throughout the world could impair political, trade and economic relations worldwide. Changes in policy in the U.S. and other countries regarding international trade, including import and export regulation and international trade agreements, could negatively impact our business. U.S. imposed tariffs on goods imported from China and certain other countries has resulted in retaliatory tariffs by China and other countries. Additional tariffs or further retaliatory trade measures taken by China or other countries in response, could affect the demand for our products and services and could impact the supply materials we use to manufacture our products. There is also uncertainty surrounding the impact of recent U.S. elections on existing and future healthcare legislation, which could have a material adverse impact on our business.
Intellectual Property Risks
To remain competitive, we must continue to develop and obtain proprietary technology rights; otherwise, we may lose market share or need to reduce prices as a result of competitors selling lower priced or technologically superior products or services that compete with our products.
Our ability to compete successfully in the diagnostic market depends on continued development and introduction of new proprietary technology and the improvement of existing technology. If we cannot continue to improve upon or develop, obtain and protect proprietary technology, we may lose market share or need to reduce prices as a result of competitors selling lower priced or technologically superior products or services that compete with our products, and our operating results could be adversely affected.
Our competitive position is heavily dependent on obtaining and protecting our own proprietary technology or obtaining licenses from others. Our ability to obtain patents and licenses, and their benefits, is uncertain.
We have issued patents both in the U.S. and internationally in various countries including, among others, Australia, Canada, China, Japan, various European countries and South Africa. Additionally, we have patent applications pending in the U.S. and various foreign jurisdictions. These pending patent applications may not result in the issuance of any patents, or if issued, may not have priority over others’ applications or may not offer meaningful protection against competitors with similar technology or may not otherwise provide commercial value. Moreover, any patents issued to us may be challenged, invalidated, found unenforceable or circumvented in the future. Third parties can make, use and sell products covered by our patents in any country in which we do not have patent protection.
We also license the right to use our products to our customers under label licenses that are for research purposes only. These licenses could be contested and, because we cannot monitor all potential unauthorized uses of our proprietary technology around the world, we might not be aware of an unauthorized use or might not be able to enforce the license restrictions in a cost-effective manner.
Our current and future licenses may not be adequate for the operation of our business. In the future, we expect that we will require or desire additional licenses from other parties in order to refine our products further and to allow us to develop, manufacture and market commercially viable or superior products. We may not be able to obtain licenses for technology patented by others that is required to produce our products on commercially reasonable terms, if at all.
To protect or enforce our patent rights, it may be necessary for us to initiate patent litigation proceedings against third parties, such as infringement suits or interference proceedings. These lawsuits would be expensive, take significant time and could divert management’s attention from other business concerns. In the event that we seek to enforce any of our patents
23



against an infringing party, it is likely that the party defending the claim will seek to invalidate the patents we assert, which could put our patents at risk of being invalidated, held unenforceable, or interpreted narrowly, and our patent applications at risk of not being issued. If we pursue any such claim, our claims could fail or the damages or other remedies awarded to us, if any, could hold little to no economic value. Further, these lawsuits may provoke the defendants to assert claims against us, which carries further risk, described in a separate risk factor below.
In addition to our patents, we rely on confidentiality agreements and other similar arrangements with our employees and other persons who have access to our proprietary and confidential information, together with trade secrets and other common law rights, to protect our proprietary and confidential technology. These agreements and laws may not provide meaningful protection for our proprietary technology in the event of unauthorized use or disclosure of such information or in the event that our competitors independently develop technologies that are substantially equivalent or superior to ours. Moreover, the laws of some foreign jurisdictions may not protect intellectual property rights to the same extent as those in the U.S. In the event of unauthorized use or disclosure of such information, if we encounter difficulties or are otherwise unable to effectively protect our intellectual property rights domestically or in foreign jurisdictions, our business, operating results and financial condition could be materially and adversely affected.
Intellectual property risks and third-party claims of infringement, misappropriation of proprietary rights or other claims against us could adversely affect our ability to market our products, require us to redesign our products or attempt to seek licenses from third parties, and materially adversely affect our operating results. In addition, the defense of such claims could result in significant costs and divert the attention of our management and other key employees.
Companies in or related to our industry often aggressively protect and pursue their intellectual property rights. In developing and producing new products and entering new markets, we may not be able to obtain, at reasonable cost or upon commercially reasonable terms, if at all, licenses to intellectual property of others that is alleged to be part of such new or existing products. From time to time, we have received, and may continue to receive, notices that claim we have infringed upon, misappropriated or misused other parties’ proprietary rights. Moreover, we are and have been subject to litigation with parties that claim, among other matters, that we infringed their patents or other intellectual property rights.
We have hired and will continue to hire individuals or contractors who have experience in medical diagnostics and these individuals or contractors may have confidential trade secret or proprietary information of third parties. These individuals or contractors may use third-party information in connection with performing services for us or otherwise reveal this third-party information to us. For these and other reasons, we could be sued for misappropriation of proprietary information and trade secrets. Such claims are expensive to defend and could divert our attention and result in substantial damage awards and injunctions that could have a material adverse effect on our business, financial condition or results of operations. In addition, to the extent that individuals or contractors apply technical or scientific information independently developed by them to our projects, disputes may arise as to the proprietary rights to such data and may result in litigation.
The defense and prosecution of patent and trade secret claims are both costly and time consuming. We or our customers may be sued by other parties that claim that our products have infringed their patents or misappropriated their proprietary rights or that may seek to invalidate one or more of our patents. An adverse determination in any of these types of disputes could prevent us from manufacturing or selling some of our products, limit or restrict the type of work that employees involved with such products may perform for us, increase our costs and expose us to significant liability.
As a general matter, our involvement in litigation or in any claims to determine proprietary rights, as may arise from time to time, could materially and adversely affect our business, financial condition and results of operations for reasons such as:
it may of itself cause our distributors or end-users to reduce or terminate purchases of our products;
it may consume a substantial portion of our managerial and financial resources;
the outcome of such litigation would be uncertain and a court may find any third-party patent claims valid and infringed by our products (issuing a preliminary or permanent injunction) that would require us to procure costly licensing arrangements from third parties or withdraw or recall such products from the market, redesign such products offered for sale or under development or restrict employees from performing work in their areas of expertise;
governmental agencies may commence investigations or criminal proceedings against our employees, former employees and us relating to claims of misappropriation or misuse of another party’s proprietary rights;
an adverse outcome could subject us to significant liability in the form of past royalty payments, penalties, special and punitive damages, the opposing party’s attorneys’ fees, and future royalty payments significantly affecting our future earnings; and
24



failure to obtain a necessary license (upon commercially reasonable terms, if at all) upon an adverse outcome could prevent us from selling our current products or other products we may develop.
Even if licenses to intellectual property rights are available, they can be costly. We have entered into various licensing agreements, which largely require payments based on specified product sales and/or the achievement of specific milestones. Royalty and license expenses under these arrangements collectively totaled $2.4 million, $1.1 million and $0.4 million for the years ended December 31, 2020, 2019 and 2018, respectively.
In addition to the foregoing, we may also be required to indemnify certain customers, distributors and strategic partners under our agreements with such parties if a third party alleges or if a court finds that our products or activities have infringed upon, misappropriated or misused another person’s proprietary rights. Further, our products may contain technology provided to us by other parties such as contractors, suppliers or customers. We may have little or no ability to determine in advance whether such technology infringes the intellectual property rights of a third party. Our contractors, suppliers and licensors may not be required or financially able to indemnify us in the event that a claim of infringement is asserted against us, or they may be required to indemnify us only up to a maximum amount, above which we would be responsible for any further costs or damages
Government and Regulatory Risks
Our COVID-19 products were approved by the FDA through an EUA and the loss of such authorization could have a material adverse impact on our business, results of operations, financial position and cash flows.
The FDA can authorize the emergency use of an unapproved medical product or an unapproved use of an approved medical product for certain emergency circumstances after the Health and Human Services Secretary has made a declaration of emergency justifying authorization of emergency use. An EUA allows use in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions caused by emerging infectious disease threats when there are no adequate, approved, and available alternatives. The FDA may also waive otherwise-applicable current good manufacturing practice (“CGMP”) requirements to accommodate emergency response needs. All of our current COVID-19 products for testing for the COVID-19 virus were obtained under EUAs. EUAs are only effective until the emergency declaration by the Human Services Secretary ends and EUAs can also be revised or revoked by the FDA at any time as the FDA continues to evaluate the available data concerning the efficacy and safety of the product, including with respect to whether there exists superior approved products. The loss of one or more of our EUAs for our COVID-19 products could have a material adverse effect on our business, results of operations, financial position or cash flows.
Our business and products are highly regulated by various governmental agencies. Our results of operations would be negatively affected by failures or delays in the receipt of regulatory approvals, clearances or authorizations, the loss of previously received approvals or other changes to existing laws and regulations that adversely impact our ability to manufacture and market our products.
The testing, manufacture and sale of our products are subject to regulation by numerous governmental authorities in the U.S., principally the FDA and corresponding state and foreign regulatory agencies. For example, the FDA regulates most of our products, which are currently all Class I or II devices. Our future performance depends on, among other matters, if, when and at what cost we will receive regulatory approval, clearances or authorizations for new products in the U.S. and internationally. Regulatory review can be a lengthy, expensive and uncertain process, making the timing and costs of clearances and approvals difficult to predict. Similarly, conducting clinical studies that may be required for regulatory approvals or clearances is a complex, time-consuming and expensive process, requiring months or years to complete, and our studies are not guaranteed to generate data that demonstrate safety and effectiveness or substantial equivalence of the evaluated product.
In addition, even after we obtain necessary authorizations, clearances or approvals to market our products, the FDA and other regulatory agencies may require post-market testing and additional surveillance to monitor the performance and use of approved products or may place conditions on any product approvals that could restrict the commercial applications of those products. Our results of operations would be negatively affected by failures or delays in the receipt of regulatory authorizations, approvals or clearances, changes in laws and regulations, the loss of previously received authorizations, approvals or clearances or the placement of limits on the manufacture, marketing and use of our products. For example, prior to our acquisition of the Triage Business, the Summers Ridge, San Diego manufacturing facility was subject to a 2012 FDA inspection that resulted in an FDA warning letter and recalls of certain Triage products and revised release specifications for certain Triage meter-based products, which will not be formally closed-out with the FDA until after a future inspection. We cannot assure you that the government will find efforts to resolve the FDA warning letter to be satisfactory. We cannot predict whether other
25



governments’ regulatory authorities will require additional remedial or corrective actions in the future, and the issues arising out of the FDA inspection may be expanded to cover other matters.
We are also subject to the provisions of a federal law commonly known as the anti-kickback statute, and several similar state laws, which prohibit payments intended to induce physicians or others to arrange for or recommend the acquisition of healthcare products or services. While the federal law applies only to products or services for which payment may be made by a federal healthcare program, state laws often apply regardless of whether federal funds may be involved. These laws constrain the sales, marketing and other promotional activities of manufacturers of medical devices by limiting the kinds of financial arrangements, including sales programs that may be used with hospitals, physicians, laboratories and other potential purchasers of medical devices, including our products.
The advertising, marketing, and labeling of medical devices is highly regulated by the FDA and Federal Trade Commission (“FTC”). Our efforts to promote our products, including via direct-to-consumer marketing or social media initiatives, could subject us to additional scrutiny of our communication of risk information, benefits or claims, by the FDA, FTC, or both.
We must also comply with numerous other laws applicable to billing and payment for healthcare services, including privacy laws. Failure to comply with these requirements may result in non-payment, refunds, exclusion from government healthcare programs and civil or criminal liabilities, any of which may have a material adverse effect on our revenues, earnings and cash flows. In addition, failure by third-party payers to properly process our payment claims in a timely manner could delay our receipt of payment for our products, which may have a material adverse effect on our cash flows.
Our contracts with government entities involve future funding, compliance, and possible sanctions risks
During 2020, we significantly expanded the number and scope of contracts we entered into with government entities. These contracts involve future funding and compliance risks. These contracts, like our National Institute of Health RADx-ATP contract, are subject to risks such as lack of funding or termination and heightened legal compliance requirements, and we may not be able to meet key deliverables and milestones. These contracts might not be renewed or might be terminated for convenience with little or no prior notice. Government contracts may expose us to higher potential liability than do other types of contracts. In addition, government contracts typically are subject to procurement laws that include socio-economic, employment practices, environmental protection, recordkeeping and accounting and other requirements. For example, our contracts with the U.S. government generally require us to comply with the Federal Acquisition Regulations, U.S. False Claims Act, Procurement Integrity Act, Buy American Act and Trade Agreements Act. We are subject to government audits, investigations and oversight proceedings. Government agencies routinely review and audit government contractors to determine whether they are complying with contractual and legal requirements. Implementing policies, procedures and controls relating to the accounting and recordkeeping requirements is expensive and could divert management’s attention from other concerns. If we fail to comply with these requirements, or we fail an audit, we are subject to various sanctions such as monetary damages, criminal and civil penalties, termination of contracts and suspension or debarment from government contract work. These requirements complicate our business and increase our compliance burden. The failure to meet key deliverables, milestones or compliance requirements could harm our reputation and might have a materially adverse impact on our business operations and our financial position or results of operations.
If one or more of our products is claimed to be defective, we could be subject to claims of liability and harm to our reputation that could adversely affect our business.
Our business involves an inherent risk of product liability claims. Our product development and production processes are complex and could expose our products to claims of defectiveness. Alleged manufacturing and design defects could lead to recalls (either voluntary or required by the FDA or other government authorities) and could result in the removal of one or more of our products from the market. Similarly, our diagnostic products could lead to a false positive or false negative result, affecting the eventual diagnosis or treatment of a patient and could lead to allegations that our products have caused injury or are found to be unsuitable for their intended use. We believe the risk of a product liability claim is heightened for at-home tests that may be purchased and administered by the end user customer and not a medical professional and our communication of risk information, benefits or claims, which is highly regulated by the FTC and FDA could be alleged to be misleading or erroneous. It is possible that we will receive adverse judgments in such lawsuits, and any such adverse judgments could be material. A defect or claim of a defect in the design or manufacture of our products could also have a material adverse effect on our reputation in the industry. Moreover, any product liability or other claim brought against us, regardless of merit, could be costly to defend.
26



We use hazardous materials in our business that may result in substantial claims against us relating to handling, storage or disposal.
We are subject to other substantial regulation relating to environmental, health and safety matters, including occupational health and safety, environmental protection, hazardous substance control, and waste management and disposal. Compliance with such laws and regulations requires significant effort and costs. For example, our research and development and manufacturing activities involve the controlled use of hazardous materials that may be subject to federal statutes commonly known as the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”), Resource Conservation and Recovery Act (“RCRA”), and the Clean Water Act, among other laws and regulations. In addition, if any governmental authorities impose new regulations with additional compliance burdens or alter their interpretation of the requirements of such existing regulations, such regulations could impair our research, development or production efforts by imposing additional, and possibly substantial, costs, restrictions or compliance procedures on our business or operations.
Given the nature of the penalties provided for in some of these regulations, we could be required to pay sizable fines, penalties or damages in the event of noncompliance with laws. Any violation or remediation requirement could also partially or completely shut down our research and manufacturing facilities and operations, which would have a material adverse effect on our business. Further, accidental contamination or injury from these hazardous materials could lead to exposure of these materials to individuals, which could result in substantial fines, penalties or damages that are not covered by insurance
Risks Related to Our Acquisitions
If we are not able to manage our growth strategy or if we experience difficulties identifying or integrating companies or technologies we may acquire, our operating results may be adversely affected.
Our business strategy contemplates further growth, which we expect to result in expanding the scope of operating and financial systems and the geographical area of our operations, including further expansion outside the U.S., as new products and technologies are developed and commercialized or new geographical markets are entered. Because we have a relatively small executive team, acquisitions and other future growth may divert management’s attention from other aspects of our business and place a strain on existing management and our operational, financial and management information systems. Furthermore, we may expand into markets in which we have less experience or incur higher costs. Some of our growth is expected to come from acquisitions of businesses and technologies. However, we cannot be certain that we will be able to successfully identify and acquire attractive targets.
Other risks associated with acquiring other technologies or businesses, include:
we may not realize our anticipated benefits and cost savings within our expected time frame, or at all, or may experience unexpected costs and expenditures;
difficulties transitioning and integrating the operations of companies or technologies that we acquire with our own operations, including difficulties integrating personnel, information systems, and internal control systems;
adverse effects on our existing business relationships;
potential loss of management and other key employees of the acquired businesses and inability to attract new employees;
potential litigation arising from the acquired business’s operations;
potential contractual, regulatory, compliance, intellectual property or employment issues;
increased exposure to international operations and sales, including fluctuations in foreign currency; and other economic, political and regulatory risks;
write-downs of goodwill, intangible assets or other assets associated with the acquisitions; and
inability to obtain financing for acquisitions on satisfactory terms, or at all.
We can give no assurance that we will be able to successfully identify, complete and integrate strategic acquisitions. Should we encounter difficulties in managing these tasks and risks, our growth strategy may suffer and our revenue, profitability and financial condition could be adversely affected.
Our acquisition of Alere’s Triage® and BNP Businesses presents certain risks to our business and operations
On October 6, 2017, we acquired the Triage and BNP Businesses from Alere. The acquisition of these businesses presents the risk that the deferred consideration payable to Alere for the BNP Business will be payable even if BNP sales are significantly reduced, or even terminate, whether as a result of the introduction of a competing product, a determination that
27



provisions of the contractual arrangement with Beckman are unenforceable or otherwise. Relatedly, as further described in Note 8 to the Consolidated Financial Statements contained in Part II, Item 8 of this Annual Report, Beckman Coulter, Inc. (“Beckman”) filed a lawsuit against us in November 2017. The lawsuit relates to a contractual arrangement with Beckman we acquired in October 2017 as part of the BNP Business for the supply of antibodies and other inputs related to, and distribution of, the Triage® BNP Test for the Beckman Coulter Access Family of Immunoassay Systems. The outcome of such lawsuit may affect the value of the assets and liabilities we acquired and expose us to monetary liability. If this lawsuit is resolved against us, we may be liable for significant damages and restraints on our business, which could adversely affect our results of operations and financial condition.
Corporate Finance Risks
We may need to raise additional funds to finance our future capital or operating needs, which could have adverse consequences on our operations and the interests of our stockholders.
We may need to seek to raise funds through the issuance of public or private debt or the sale of equity to achieve our business strategy. In addition, we may need debt or equity financing to complete acquisitions. If we raise funds or acquire other technologies or businesses through issuance of equity, this could dilute the interests of our stockholders. Such financing activities may also depress the market price of shares of our common stock and impair our ability to raise capital through the sale of additional equity securities. Moreover, the availability of additional capital, whether debt or equity from private capital sources (including banks) or the public capital markets, fluctuates as our financial condition and industry or market conditions in general change. There may be times when the private capital markets and the public debt or equity markets lack sufficient liquidity or when we cannot otherwise raise additional capital or issue additional debt on acceptable terms, if at all.
Additional indebtedness could be costly or have adverse consequences, such as:
requiring us to dedicate a substantial portion of our cash flows from operations to payments on our debt;
limiting our ability to obtain future financing for working capital, capital expenditures, acquisitions, debt obligations and other general corporate requirements;
making us more vulnerable to adverse conditions in the general economy or our industry and to fluctuations in our operating results, including affecting our ability to comply with and maintain any financial tests and ratios required under our indebtedness;
limiting our flexibility to engage in certain transactions or to plan for, or react to, changes in our business and the diagnostics industry;
putting us at a disadvantage compared to competitors that have less relative and/or less restrictive debt; and
subjecting us to additional restrictive financial and other covenants.
If we incur substantial additional indebtedness in the future, these higher levels of indebtedness may affect our ability to pay the principal of and interest on existing indebtedness and our creditworthiness generally. Our business may not continue to generate cash flow from operations in the future sufficient to service or repay our debt. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.
Our debt, deferred and contingent payment obligations could materially adversely affect our financial condition and results of operations.
We have a $175.0 million Revolving Credit Facility as described in Note 3 to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report, and may incur other indebtedness from time to time. We currently have no borrowings under the Revolving Credit Facility, but we will continue to have the ability to borrow under the facility. We also have significant deferred and contingent payment obligations for the BNP Business acquisition as described in Note 10 to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report. In addition to our Revolving Credit Facility, we will continue to have the ability to incur additional debt.
The degree to which we are leveraged and are subject to deferred and contingent payment obligations could have important or materially adverse consequences to our business and operating results, including:
our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions and general corporate purposes may be impaired;
the payment of our deferred and contingent payment obligations reduces the funds available to us for our operations and other strategic objectives;
28



our debt agreements contain, and any agreements to refinance our debt likely will contain, financial and other restrictive covenants, and our failure to comply with them may result in an event of default, which, if not cured or waived, could have a material adverse effect on us;
our level of indebtedness and deferred and contingent payment obligations may increase our vulnerability to, and reduce our flexibility to respond to, general economic downturns and adverse industry and business conditions;
to the extent the debt we incur requires collateral to secure such indebtedness, our assets could be at risk and our flexibility related to such assets could be limited;
our debt service and deferred and contingent payment obligations could limit our flexibility in planning for, or reacting to, changes in our business and industry;
any borrowings under our Revolving Credit Facility will be at variable rates of interest, which may result in higher interest expense in the event of market interest rates; and
any default under our Revolving Credit Facility may result in proceedings against collateral we have used to secure such borrowings, including substantially all of our and our guarantor subsidiaries’ assets.
General Risk Factors
Our business could be negatively affected by the loss of or the inability to hire key personnel.
Our future success depends in part on our ability to retain our key personnel, including manufacturing, research and development, technical, sales, marketing and executive personnel and our ability to identify and hire additional qualified personnel. Competition for these personnel is intense, both in the industry in which we operate and where our operations are located. Further, we expect to grow our operations, and our needs for additional management and other key personnel are expected to increase. If we fail to retain existing key personnel, or timely identify and hire replacement or additional qualified personnel to meet expected growth, such failure could adversely impact our business. In addition, the loss of any of our key personnel, particularly key manufacturing, research and development and technical personnel, could harm our business and prospects and could impede the achievement of our research and development, operations or strategic objectives.
We are subject to, and may in the future become subject to, claims and litigation that could result in significant expenses and could ultimately result in an unfavorable outcome for us.
From time to time, we are involved in litigation and other proceedings, including matters related to product liability claims, commercial disputes and intellectual property claims, as well as regulatory, employment, and other claims related to our business. Litigation related to our company, our business, and our operations or financial performance may also involve customers, competitors, suppliers, patients, shareholders, governmental authorities or other third parties. Litigation can be lengthy, expensive and disruptive to our operations, and results cannot be predicted with certainty. An adverse decision could result in significant settlement amounts, monetary damages, fines or injunctive relief that could affect our financial condition or results of operations. Even if lawsuits do not result in an unfavorable outcome, the costs of defending or prosecuting such lawsuits may be material to our business and our operations. Moreover, these lawsuits may divert management’s attention from the operation of our business, which could adversely affect our business and results of operations.
Furthermore, in the ordinary course of business, we must frequently make subjective judgments with respect to compliance with applicable laws and regulations. If regulators disagree with the manner in which we have sought to comply with applicable laws and regulations, we could be subjected to substantial civil and criminal penalties, as well as field corrective actions, product recalls, seizures or injunctions with respect to the sale of our products. The assessment of any civil and criminal penalties against us could severely impair our reputation within the industry and affect our operating results, and any limitation on our ability to manufacture and market our products could also have a material adverse effect on our business.
We are exposed to business risk which, if not covered by insurance, could have an adverse effect on our results of operations.
We face a number of business risks, including exposure to product liability claims. Although we maintain insurance for a number of these risks, we may face claims for types of damages, or for amounts of damages, that are not covered by our insurance. For example, there is a risk that product liability or other claims may exceed the amount of our insurance coverage or may be excluded from coverage under the terms of our policy. Also, our existing insurance may not be renewed at the same cost and level of coverage as currently in effect or may not be renewed at all. Further, we do not currently have insurance against many environmental risks we confront in our business. If we are held liable for a claim against which we are not insured or for damages exceeding the limits of our insurance coverage, whether arising out of product liability matters, cybersecurity matters, or from some other matter, that claim could have a material adverse effect on our results of operations.
29



Changes in our tax rates or exposure to additional income tax liabilities or assessments could affect our profitability.
We are subject to income taxes in the U.S. and in various non-U.S. jurisdictions. In addition, the amount of income taxes we pay is subject to ongoing audits by U.S. federal, state and local tax authorities and by non-U.S. tax authorities. Due to the potential for changes to tax laws (or changes to the interpretation thereof) and the ambiguity of tax laws, the subjectivity of factual interpretations, the complexity of our foreign operations and intercompany arrangements and other factors, our estimates of income tax assets or liabilities may differ from actual payments, assessments or receipts. If these audits result in payments or assessments different from our reserves, our future results may include unfavorable adjustments to our tax liabilities and our financial statements could be adversely affected. If we determine to repatriate earnings from foreign jurisdictions that have been considered permanently re-invested under existing accounting standards, it could also increase our effective tax rate. In addition, any significant change to the tax system in the United States or in other jurisdictions (including changes in the taxation of international income as further described below) could adversely affect our financial statements.
Some provisions of our charter documents and Delaware law may make takeover attempts difficult, which could depress the price of our stock and inhibit our stockholders’ ability to receive a premium price for their shares.
Provisions of our amended and restated certificate of incorporation could make it more difficult for a third party to acquire control of our business, even if such change in control would be beneficial to our stockholders. Our amended and restated certificate of incorporation allows our Board of Directors to issue up to five million shares of preferred stock and to fix the rights and preferences of such shares without stockholder approval. Any such issuance could make it more difficult for a third party to acquire our business and may adversely affect the rights of our stockholders. Our amended and restated bylaws include advance notice requirements for stockholder proposals that require stockholders to give written notice of any proposal or director nomination to us within a specified period of time prior to any stockholder meeting and do not permit stockholders to call a special meeting of the stockholders, unless such stockholders hold at least 50% of our stock entitled to vote at the meeting. We are also subject to anti-takeover provisions under Delaware law. These provisions may delay, deter or prevent a change in control of us, adversely affecting the market price of our common stock.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion of our financial condition and results of operations contains forward-looking statements within the meaning of the federal securities laws that involve material risks and uncertainties. This discussion should be read in conjunction with “A Warning About Forward-Looking Statements” on page 3 and “Risk Factors” in this Annual Report. In addition, our discussion of the financial condition and results of operations of Quidel Corporation in this Item 7 should be read in conjunction with our Consolidated Financial Statements and the related Notes included elsewhere in this Annual Report. Discussions of year-to-year comparisons between 2019 and 2018 that are not included in this Annual Report can be found in our Annual Report for the year ended December 31, 2019.
Overview and Executive Summary
We have a leadership position in the development, manufacturing and marketing of rapid diagnostic testing solutions. These diagnostic testing solutions we separate into our four product categories: rapid immunoassay, Cardiometabolic immunoassay, molecular diagnostic solutions and specialized diagnostic solutions. We currently sell our products directly to end users and distributors, in each case, for professional use in physician offices, hospitals, clinical laboratories, reference laboratories, urgent care clinics, leading universities, retail clinics, pharmacies and wellness screening centers. We market our products through a network of distributors and through a direct sales force. We operate in one business segment that develops, manufactures and markets our four product categories.
For the year ended December 31, 2020, total revenue increased 211% to $1,661.7 million as compared to the year ended December 31, 2019, and currency exchange rates had a minimal impact on the growth rate. Our revenues can be highly concentrated over a small number of products. For the year ended December 31, 2020, sales of our COVID-19 products accounted for 70% of total revenue. For the years ended December 31, 2020, 2019 and 2018, sales of our influenza products, as a percentage of total revenue, accounted for 8%, 26%, and 24% respectively. Additionally, a significant portion of our total revenue is from a relatively small number of distributors. Approximately 68%, 51% and 49% of our total revenue for the years ended December 31, 2020, 2019 and 2018, respectively, were related to sales through our four largest distributors.
Our primary mission is to advance diagnostics to improve human health. Our strategy is to target market segments that represent significant total market opportunities, and in which we can be successful by applying our expertise and know-how to develop differentiated technologies and products.
Our diagnostic testing solutions are designed to provide specialized results that serve a broad range of customers, by addressing the market requirements of ease of use, reduced cost, increased test accuracy and reduced time to result. Our current approach is to offer products in the following product categories:
rapid immunoassay tests for use in physician offices, hospital laboratories and emergency departments, retail clinics, eye health settings, pharmacies, other urgent care or alternative site settings to include over the counter commencing in 2021;
cardiometabolic immunoassay tests for use in physician offices, hospital laboratories and emergency departments, and other urgent care or alternative site settings;
molecular diagnostic tests for use in hospitals, moderately complex physician offices, laboratories and other settings; and
specialized diagnostic solutions, including direct DFA and culture-based tests for the clinical virology laboratory and other products serving the bone health, autoimmune and complement research communities.
In order to achieve our mission, our strategy is to do the following:
focus on innovative products and markets and leverage our core competency in new product development for our QuickVue®, Sofia® and Triage® immunoassay brands and next-generation products;
leverage our manufacturing expertise to address increasing demand for our products, including through expanded manufacturing capacity;
utilize our molecular assay development competencies to further develop our molecular diagnostics franchise that includes distinct testing platforms, such as Lyra®, Solana® and Savanna®; and
strengthen our position with distribution partners and our end-user customers to gain more emphasis on our products and enter new markets.
35



Our current initiatives to execute this strategy include the following:
provide products that can compete effectively in the healthcare market where cost and quality are important;
focus our research and development efforts on three areas:
new proprietary product platform development;
the creation of new and improved products for use on our established platforms to address unmet clinical needs, and
pursuit of collaborations with, or acquisitions of, other companies for new and existing products and markets that advance our differentiated strategy;
leverage our international infrastructure and enhance our global footprint to support our international operations and future growth;
strengthen our market and brand leadership in current markets by acquiring and/or developing and introducing clinically superior diagnostic solutions;
strengthen our direct sales force to enhance relationships with integrated delivery networks, laboratories and hospitals, with a goal of driving growth through improved physician and laboratorian satisfaction;
leverage our wireless connectivity and data management systems, including cloud-based tools;
support payer evaluation of diagnostic tests and establishment of favorable reimbursement rates;
provide clinicians with validated studies that encompass the clinical efficacy and economic efficiency of our diagnostic tests for the professional market;
pursue alternative markets for point-of-care diagnostics;
create strong global alliances to support our efforts to achieve leadership in key markets and expand our presence in emerging markets;
further refine our manufacturing efficiencies and productivity improvements to increase profit; and
pursue potential acquisitions to support our strategic initiatives.
Impact of COVID-19 Pandemic
Events surrounding the SARS-CoV-2 virus that emerged in late 2019 and the ensuing global pandemic has had a dramatic impact on businesses globally and our business as well. The severity and duration of the pandemic and economic repercussions of the virus and government actions in response to the pandemic remain uncertain and will ultimately depend on many factors, including the speed and effectiveness of the containment efforts throughout the world, the duration and spread of the virus as well as potential seasonality or new outbreaks.
In the United States, federal, state, and local government directives and policies have been put in place to manage public health concerns and address the economic impacts, including sharply reduced business activity, increased unemployment, and overall uncertainty presented by this new healthcare challenge. Similar actions have been taken by governments around the world. While all our sites are currently operational globally, our facilities could be required to temporarily curtail production levels or temporarily cease operations based on government mandates or as a result of the pandemic. To mitigate risks, we continue to evaluate the nature and extent COVID-19 may have to our business and operations and adjust risk mitigation planning and business continuity activities as needed.
New SARS-CoV-2 Diagnostic Products
As a leader in point-of-care diagnostics and with established expertise in respiratory infectious disease products, we are well-positioned to respond to the COVID-19 pandemic. We worked closely with national and local governments, agencies, and industry partners to develop, manufacture and supply critical diagnostic products to support testing initiatives to help curb the spread of the SARS-CoV-2 virus. In particular, we have developed new molecular and antigen products to diagnose the SARS-CoV-2 virus. We have experienced exceptional demand for such products. In response, we have committed and continue to commit significant resources toward the expansion of our production capacity.
We expect demand for our molecular and antigen assays and instruments to continue for the near-term at elevated levels, especially in the United States. At the same time, we also have observed decreased demand for certain of our other diagnostic products in connection with customers closing or decreasing their operations and/or patients deferring treatment. The extent to which COVID-19 will impact demand for our products depends on future developments, which are highly uncertain and very difficult to predict, including new information that may emerge concerning the severity of the coronavirus, impact of new SARS-CoV-2 variants and actions to contain and treat its impacts, including the vaccination programs now being implemented.
36



Operations and Employee Safety
While many governments have implemented lockdown and shelter-in-place orders, requiring non-essential businesses to shut down operations, our business is deemed “essential” and we have continued to operate, manufacture and distribute products to customers. We have implemented preparedness plans designed to help protect the safety of our employees and maintain operational continuity with an emphasis on manufacturing, product distribution and product development during this crisis. To date, we have been able to maintain our operations without significant interruption and have been able to develop and quickly scale manufacturing capacity for new products related to the COVID-19 pandemic.
To mitigate the pandemic’s impact, we have transitioned many non-essential employees to work remotely, and have implemented preventative protocols intended to help safeguard our on-site employees and maintain business continuity in the event government restrictions or severe outbreaks impact our operations at certain sites. We have also enhanced cleaning and sanitizing procedures, provided additional personal hygiene supplies and protective equipment to personnel, implemented health screening protocols and periodic testing for essential personnel, limited access to facilities to outside persons who are not critical to continuing our operations, trained employees on guidelines for social distancing and face coverings and isolation and quarantine of personnel as we deem appropriate given the facts, circumstances and applicable laws or regulations. These measures have created additional burdens on our infrastructure and information technology systems and may result in decreased productivity and increased operating costs. However, the various responses we have put in place have to date resulted in limited disruption to our normal business operations.
Supply Chains
As a result of the COVID-19 pandemic, we have seen delays in receipts for certain raw materials and components for our products. Such delays can result in disruption to our business operations. We are continuously evaluating our supply chain to identify potential gaps and take steps intended to ensure continuity. We have considered potential political, legal or regulatory actions that could be taken as a result of the pandemic in jurisdictions where we manufacture, source or distribute products that could impact our supply of products to our customers or the availability of raw materials and components from our suppliers. We cannot currently predict the frequency, duration or scope of these government actions and any supply disruptions, and the availability of various products is dependent on our suppliers, their location and the extent to which they are impacted by the COVID-19 pandemic, among other factors. We are proactively working with manufacturers, industry partners and government agencies to help meet the needs of our customers during the pandemic.
Our inventory levels continue to fluctuate due to supply chain constraints in conjunction with larger and more frequent customer orders. In response, we have added alternate suppliers for certain critical components and instruments, increased inventory of raw materials needed in our operations, increased manufacturing capacity and continue to explore opportunities for further expansion in our Athens, Ohio and San Diego, California facilities. In January 2021, we significantly expanded our capacity by entering into a long-term lease for an additional manufacturing facility in Carlsbad, California. This facility is expected to begin operations in the second half of 2021.
We are seeking to minimize the impact of delays and secure allocations of vital raw materials to meet extremely high demand for our products. However, dependent on the duration and continued intensity of the current pandemic, we may experience some sort of interruption to our supply chains, and such an interruption could materially affect our ability to timely manufacture and distribute our products and unfavorably impact our results of operations depending on the nature and duration of such interruption.
Outlook
We anticipate continued revenue growth over the next year, including increased sales of testing products related to the COVID-19 pandemic, with a positive impact on gross margin and earnings. We expect to continue to invest heavily in research and development activities for our next generation immunoassay and molecular platforms as well as additional assays to be launched on our current platforms, with the most recent focus on assays to address the COVID-19 pandemic. Additionally, we are making substantial investments in the expansion of our production capacity in response to the demand driven by the COVID-19 pandemic. We intend to continue our focus on prudently managing our business and delivering improved financial results, while at the same time striving to introduce new products into the market and maintain our emphasis on research and development investments for longer term growth. Finally, we expect to continue to evaluate opportunities to acquire new product lines, technologies and companies.

Results of Operations
Comparison of years ended December 31, 2020 and 2019
Our fiscal year is the 52 or 53 weeks ending the Sunday closest to December 31. Fiscal year 2020 was 53 weeks and fiscal year 2019 was 52 weeks.

Total Revenues
The following table compares total revenues for the years ended December 31, 2020 and 2019 (in thousands, except percentages):
For the year ended December 31,Increase (decrease)
 20202019$%
Rapid Immunoassay$1,144,831 $191,736 $953,095 497 %
Cardiometabolic Immunoassay242,933 266,505 (23,572)(9)%
Molecular Diagnostic Solutions222,964 21,716 201,248 927 %
Specialized Diagnostic Solutions50,940 54,933 (3,993)(7)%
Total revenues$1,661,668 $534,890 $1,126,778 211 %
For the year ended December 31, 2020, total revenues increased 211% to $1,661.7 million. The Rapid Immunoassay category was the largest contributor to revenue growth, driven by the Sofia SARS Antigen and Sofia 2 Flu + SARS Antigen Immunoassays. Molecular Diagnostic Solutions sales grew $201.2 million over the prior year, driven by the Lyra SARS-CoV-2 assays. The decrease in Cardiometabolic Immunoassay and Specialized Diagnostic Solutions sales was mainly due to lower demand during the COVID-19 pandemic. Currency exchange rate impact for the period was favorable by $0.7 million, which had a minimal impact on the growth rate. See further discussion in Item 7A of this Annual Report for additional information related to our calculation and use of constant currency and constant currency revenue growth.
Gross Profit
Gross profit increased to $1,348.9 million, or 81% of revenue for the year ended December 31, 2020, compared to $320.8 million, or 60% of revenue for the year ended December 31, 2019. The increased gross profit was driven by the demand for our SARS-CoV-2 products, which drove improved product mix. In addition, higher production volumes contributed to increased manufacturing overhead absorption, which offset increases in spend required to expedite the production ramp. Gross margin improved compared to the same period in the prior year due to the same factors.

Research and Development Expense
Research and development expense for the year ended December 31, 2020 increased from $52.6 million to $84.3 million due primarily to increased spending on Savanna, Sofia and next-generation instrument development projects. We also incurred higher labor, material and clinical trials spend associated with COVID-19 product development.
Research and development expenses include direct external costs such as fees paid to consultants, and internal direct and indirect costs such as compensation and other expenses for research and development personnel, supplies and materials, clinical trials and studies, facility costs and depreciation.
Due to the risks inherent in the product development process and given the early-stage of development of certain projects, we are unable to estimate with meaningful certainty the costs we will incur in the continued development of our product candidates for commercialization. We expect our research and development costs to be substantial as we move other product candidates into preclinical and clinical trials and advance our existing product candidates into later stages of development.
Sales and Marketing Expense
Sales and marketing expense for the year ended December 31, 2020 increased from $111.1 million to $134.0 million primarily due to higher employee-related costs, freight and bad debt expense, partially offset by reduced travel, meeting and trade show costs due to the COVID-19 travel restrictions.
General and Administrative Expense
General and administrative expense for the year ended December 31, 2020 increased from $52.8 million to $66.6 million due to higher compensation costs from increased headcount to support the growth experienced in 2020 as well as improved performance in the period.
Acquisition and Integration Costs
Acquisition and integration costs of $3.7 million for the year ended December 31, 2020 primarily related to the evaluation of new business development opportunities. Acquisition and integration costs of $11.7 million for the year ended December 31, 2019 consisted primarily of global operation integration costs.

$20,007 $15,538 $4,469 29 %
Interest and other expense, net decreased from $14.8 million to $9.6 million. Interest and other expense, net primarily relates to accretion of interest on the deferred consideration, coupon and accretion of interest related to our Convertible Senior Notes and interest and amortization of deferred financing costs associated with any debt outstanding under our Credit Agreement. The decrease in interest and other expense, net over the prior year was primarily due to lower debt balances under the Company’s Revolving Credit Facility and Convertible Senior Notes and lower deferred consideration liability outstanding. Such decrease was partially offset by a $1.1 million change in fair value of derivative liabilities associated with our Convertible Senior Notes conversion recorded in the second quarter of 2020.
Loss on extinguishment of debt of $10.4 million for the twelve months ended December 31, 2020 relates to the extinguishment of $5.9 million in aggregate principal of the Convertible Senior Notes converted and settled in cash during the period. Loss on extinguishment of debt of $0.7 million for the year ended December 31, 2019 relates to the extinguishment of $45.4 million in aggregate principal of the Convertible Senior Notes in exchange for the Company’s common stock during the period.
39



Income Taxes
We recognized an income tax provision of $230.0 million, resulting in an effective tax rate of 22.1% for the year ended December 31, 2020. The primary drivers of the increased income tax expense in the year ended December 31, 2020 are the increased pre-tax profits offset by the lower proportional impact from excess tax benefits from stock-based compensation. In the year ended December 31, 2019, the excess tax benefits from stock-based compensation offset a greater portion of the tax expense from earnings.
Liquidity and Capital Resources
As of December 31, 2020 and 2019, our principal sources of liquidity consisted of the following (in thousands):
 December 31,
 20202019
Cash, cash equivalents, and restricted cash$489,941 $52,775 
Amount available to borrow under the Revolving Credit Facility$175,000 $175,000 
Working capital including cash, cash equivalents, and restricted cash$805,441 $96,336 
As of December 31, 2020, we had $489.9 million in cash and cash equivalents, a $437.2 million increase from the prior year. Our cash requirements fluctuate as a result of numerous factors, such as cash generated from operations, progress in research and development or capital expansion projects and integration activities. We also intend to continue to evaluate candidates for new product lines, company or technology acquisitions or technology licensing and other strategic acquisitions and investments. If we decide to proceed with any such transactions, we may need to incur additional debt or issue additional equity to successfully complete the transactions.
Our primary source of liquidity, other than our holdings of cash and cash equivalents, has been cash flows from operations and financing. Cash generated from operations provides us with the financial flexibility we need to meet normal operating, investing and financing needs. We do not currently expect the impacts of the COVID-19 pandemic to adversely affect our liquidity and capital resources or our ability to meet financial commitments. We anticipate that our current cash and cash equivalents, together with cash provided by operating activities will be sufficient to fund our near-term capital and operating needs for at least the next 12 months. 
Normal operating needs include the planned costs to operate our business, including amounts required to fund working capital and capital expenditures. Our primary short-term needs for capital, which are subject to change, include expenditures related to:
acquisitions of equipment and other fixed assets in support of our manufacturing facility expansion;
the continued advancement of research and development efforts;
support of commercialization efforts related to our current and future products, including support of our direct sales force and field support resources;
interest on and repayments of our deferred consideration, contingent consideration and lease obligations; and
potential strategic acquisitions and investments.
Our Convertible Senior Notes matured on December 15, 2020. The Amended and Restated Credit Agreement provides us with a Revolving Credit Facility of $175.0 million and there was no balance outstanding as of December 31, 2020. The Revolving Credit Facility matures on August 31, 2023.
As of December 31, 2020, we have $11.9 million in fair value of contingent consideration and $116.0 million of deferred consideration associated with acquisitions to be settled in future periods.
On December 12, 2018, our Board of Directors authorized a stock repurchase program to purchase up to $50.0 million of the Company’s shares of common stock. On August 28, 2020, we announced an amendment to the stock repurchase program to purchase an additional $150.0 million of our shares of common stock through August 28, 2022. For the twelve months ended December 31, 2020, 257,329 shares of outstanding common stock were repurchased under our stock repurchase program for approximately $43.7 million and as of December 31, 2020, we had approximately $156.3 million available under the repurchase program.
40



Our future capital requirements and the adequacy of our available funds to service any long-term debt outstanding and to fund working capital expenditures and business development efforts will depend on many factors, including:
our ability to realize revenue growth from our new technologies and create innovative products in our markets;
outstanding debt and covenant restrictions;
our ability to leverage our operating expenses to realize operating profits as we grow revenue;
competing technological and market developments; and
our entry into strategic collaborations with other companies or acquisitions of other companies or technologies to enhance or complement our product and service offerings

Net increase in cash and cash equivalents$437,166 $9,080 
Cash provided by operating activities of $629.8 million during the twelve months ended December 31, 2020 reflects net income of $810.3 million and adjustments of $70.5 million primarily associated with depreciation, amortization, stock-based compensation, deferred taxes, loss on extinguishment of debt and accretion of interest on deferred consideration. Partially offsetting these inflows was a net working capital use of cash of $265.3 million primarily driven by increases in accounts receivable and product inventory, both associated with the increased demand due to the COVID-19 pandemic, partially offset by an increase in income taxes payable and accounts payable.
Cash provided by operating activities of $134.5 million during the year ended December 31, 2019 reflects net income of $72.9 million and non-cash adjustments of $76.8 million, primarily associated with depreciation, amortization, stock-based compensation and accretion of interest on deferred consideration. In addition, we used cash to fund our working capital requirements of $21.2 million, primarily driven by an increase in accounts receivable.
Our investing activities used $63.3 million during the twelve months ended December 31, 2020 primarily related to investments in manufacturing equipment, Sofia, Solana and Triage instruments available for lease, building improvements and scientific equipment. Our investing activities used $27.2 million during the year ended December 31, 2019 primarily related to payments for computer software, building improvements, Sofia, Solana and Triage instruments available for lease and manufacturing equipment.
We are currently planning approximately $300 million in capital expenditures over the next 12 months, of which approximately $33 million is expected to be funded through a contract with the National Institute of Health (“NIH”), entered into during the third quarter of 2020. See Note 1 in the Consolidated Financial Statements included in this Annual Report for further discussion of the NIH contract. We plan to fund the remainder of the capital expenditures with the cash on our balance sheet. The primary purpose for our capital expenditures is to invest in manufacturing capacity expansion, including implementation of our new manufacturing facility in Carlsbad, California, to acquire Sofia, Solana and Triage instruments, to acquire scientific equipment, to purchase or develop information technology and to implement facility improvements. We have $32.1 million in firm purchase commitments with respect to planned inventory purchases as of December 31, 2020.
Cash used by financing activities was $130.3 million during the twelve months ended December 31, 2020 primarily related to repurchases of common stock of $47.9 million, payment on Convertible Senior Notes and derivative liability of $43.4 million, payments on deferred consideration of $42.0 million, and acquisition contingent consideration of $6.0 million, partially offset by proceeds from issuance of stock of $9.6 million. Cash used by financing activities was $98.3 million during the year ended December 31, 2019 primarily related to payments on deferred consideration of $44.0 million, payments on the Revolving Credit Facility of $53.2 million, acquisition contingent consideration of $4.0 million and repurchases of common stock of $10.7 million, partially offset by proceeds from issuance of stock of $14.8 million from stock option exercises.

Off-Balance Sheet Arrangements
At December 31, 2020 and 2019, we did not have any relationships with unconsolidated entities or financial partners, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

(3)Reflects future minimum lease obligations on facilities and equipment under operating leases in place as of December 31, 2020. The lease for the Summers Ridge facility is subject to certain must-take provisions related to one additional building that is not included in the operating lease obligations.

(4)Reflects our $32.1 million of non-cancelable commitments for planned inventory purchases under contractual arrangements.
We have entered into various licensing agreements, which largely require payments based on product sales as well as the achievement of specific milestones. Royalty and license expenses under these various royalty and licensing agreements collectively totaled $2.4 million, $1.1 million and $0.4 million for the years ended December 31, 2020, 2019 and 2018, respectively.
We exclude liabilities pertaining to uncertain tax positions from our table of contractual obligations as we cannot make a reliable estimate of the period of cash settlement with the respective taxing authorities, nor the amount of the final cash settlement. As of December 31, 2020, we had approximately $16.6 million of liabilities associated with uncertain tax positions. See Note 4 in the Consolidated Financial Statements included in this Annual Report for further discussion of uncertain tax positions. The table also excludes $11.9 million in potential contingent consideration payments primarily related to the acquisition of the BNP Business and achievement of certain revenue targets under other acquisition agreements. We have not included amounts in the table because we cannot make a reasonably reliable estimate regarding the probability of the annual payments for the BNP Business. See Note 10 in the Consolidated Financial Statements included in this Annual Report for further discussion of our contingent consideration.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to reserve for contractual rebates, goodwill and intangible assets and income taxes. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
42



We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements:
Reserve for Contractual Rebates
The Company records revenues primarily from product sales. These revenues are recorded net of rebates that are estimated at the time of sale, and are largely driven by various customer program offerings, including special pricing agreements and promotions. Rebates are calculated based upon historical experience and estimated distributor inventory balances and recorded as a reduction of sales with offsets to trade accounts receivable. As of December 31, 2020, the reserve related to contract rebates was $100.8 million.
Goodwill and Intangible Assets
The useful lives of intangible assets with definite lives are based on the expected number of years the asset will generate revenue or otherwise be used by us and the related amortization is based on the straight-line method. Goodwill, which has an indefinite life, is not amortized but instead is tested at least annually for impairment, or more frequently when events or changes in circumstances indicate that the asset might be impaired. Examples of such events or circumstances include:
the asset’s ability to continue to generate income from operations and positive cash flow in future periods;
any volatility or significant decline in our stock price and market capitalization compared to our net book value;
loss of legal ownership or title to an asset;
significant changes in our strategic business objectives and utilization of our assets; and
the impact of significant negative industry or economic trends.
If a change were to occur in any of the above-mentioned factors or estimates, the likelihood of a material change in our reported results would increase.
For goodwill, the entity has the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. The quantitative impairment test compares the fair value of a reporting unit with the carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill is considered not impaired; otherwise, goodwill is impaired and the loss is recorded. We completed our annual evaluation for impairment of goodwill as of December 31, 2020 and determined that no impairment existed.
Income Taxes
Significant judgment is required in determining our provision for income taxes, current tax assets and liabilities, deferred tax assets and liabilities, and our future taxable income, both as a whole and in various tax jurisdictions, for purposes of assessing our ability to realize future benefit from our deferred tax assets. A valuation allowance may be established to reduce our deferred tax assets to the amount that is considered more likely than not to be realized through the generation of future taxable income and other tax planning opportunities. As of December 31, 2020, the Company has a valuation allowance of $2.3 million which represents the portion of the Company’s deferred tax assets that management believes is not more likely than not to be realized. We will continue to assess the need for a valuation allowance on our deferred tax assets by evaluating both positive and negative evidence that may exist.
We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained during an audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While we believe that we have appropriate support for the positions taken on our tax returns, we regularly assess the potential outcome of examinations by tax authorities in determining the adequacy of our provision for income taxes. See Note 4 in the Consolidated Financial Statements included in this Annual Report for more information on income taxes.
43



Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
For fixed rate debt, changes in interest rates will generally affect the fair value of the debt instrument, but not our earnings or cash flows. Under our current policies, we do not use interest rate derivative instruments to manage our exposure to changes in interest rates.
Our current investment policy with respect to our cash and cash equivalents focuses on maintaining acceptable levels of interest rate risk and liquidity. Although we continually evaluate our placement of investments, our cash equivalents as of December 31, 2020 consisted primarily of prime money market funds. The funds provide daily liquidity and may be subject to interest rate risk and fall in value if market interest rates increase. We do not expect our operating results or cash flows to be affected to any significant degree by a sudden change in market interest rates.
Foreign Currency Exchange Risk
We are exposed to foreign currency risks that arise from normal business operations. These risks include the translation of local currency balances of foreign subsidiaries, transaction gains and losses associated with intercompany loans with foreign subsidiaries and transactions denominated in currencies other than a location’s functional currency.
For the year ended December 31, 2020, total revenues were $1,661.7 million, of which approximately $119.8 million in revenue was denominated in currencies other than the U.S. dollar. We believe constant currency and constant currency growth rate enhance the comparison of our financial performance from period-to-period, and to that of our competitors. Constant currency revenue excludes the impact from foreign currency fluctuations, which was favorable $0.7 million for the year ended December 31, 2020, and is calculated by translating current period revenues using prior period exchange rates, net of any hedging effect recognized in the current period. Constant currency revenue growth (expressed as a percentage) is calculated by determining the change in current period constant currency revenues over prior period revenues.
The major currencies to which our revenues are exposed are the Euro and the Chinese Yuan. A 100-basis point move in the average exchange rates (assuming a simultaneous and immediate 100 basis point change for the relevant period) would have resulted in an increase or decrease in our reported revenue for the year ended December 31, 2020 as follows (in thousands):
CurrencyYear ended December 31, 2020
Chinese Renminbi$1,892 
Euro$2,740 
Our foreign currency management policy permits the use of derivative instruments, such as forward contracts, to reduce volatility in our results of operations resulting from foreign exchange rate fluctuations. We do not enter into foreign currency derivative instruments for trading purposes or to engage in speculative activity. See further discussion in Note 12 to the Notes to the Consolidated Financial Statements included in this Annual Report for additional information related to such forward contracts.

        REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Quidel Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Quidel Corporation (the Company) as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with US generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 18, 2021 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Reserve for contractual rebates
Description of the Matter
As described in Note 1 to the consolidated financial statements, the Company records revenues from product sales net of contractual rebates that are estimated at the time of sale. As of December 31, 2020, the Company recognized an allowance on accounts receivable of $100.8 million in rebates.

Auditing the Company’s allowance for contractual rebates is especially challenging because the calculation involves estimating adjustments to revenue based upon a high volume of data including inputs from third-party sources, such as distributor inventory levels and historical distributor sales to end users. In addition, the determination of such adjustments includes estimating rebate percentages which are dependent on estimated end-user sales mix and customer contractual terms, which vary across customers.
How We Addressed the Matter in Our Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of key controls over the Company’s process to calculate the reserves for contractual rebates, including their evaluation of third-party data inputs utilized in the reserve and accrual calculations, as well as the accuracy of the Company’s data inputs such as contractual pricing and estimated end user sales.

Our audit procedures also included the evaluation of significant inputs through the evaluation of the Company's retrospective analysis of rebates claimed compared to actual payments issued, evaluation of estimates based on historical experience, and performance of analytical procedures and sensitivity analyses over the Company’s significant inputs. We also tested the underlying data used in management’s calculations for accuracy and completeness, which included inspection of source data supporting the inventory levels and rebate claims paid subsequent to period end.

QUIDEL CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1. Company Operations and Summary of Significant Accounting Policies
Quidel Corporation (the “Company”) commenced operations in 1979. The Company operates in one business segment, which develops, manufactures and markets diagnostic testing solutions. These diagnostic tests can be categorized in the following product categories: Rapid Immunoassay, Cardiometabolic Immunoassay, Specialized Diagnostic Solutions and Molecular Diagnostic Solutions. The Company sells its products directly to end users and distributors, in each case, for professional use in physician offices, hospitals, clinical laboratories, reference laboratories, leading universities, retail clinics and wellness screening centers. The Company markets its products through a network of distributors and a direct sales force.
The accompanying consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with generally accepted accounting principles in the U.S.
Consolidation—The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Cash and Cash Equivalents—The Company considers cash equivalents to be highly liquid investments with a maturity at the date of purchase of three months or less. The Company invests its cash equivalents primarily in money market funds with high quality institutions.
Accounts Receivable—The Company sells its products directly to hospitals and reference laboratories as well as to distributors in the U.S. and internationally (see Note 9). The Company periodically assesses the financial strength of these customers and establishes reserves for anticipated losses when necessary, which historically have not been material. The balance of accounts receivable is net of reserves of $103.4 million and $16.0 million at December 31, 2020 and 2019, respectively, of which the reserve related to contract rebates was $100.8 million and $15.7 million, respectively.
Concentration of Credit Risk—Financial instruments that potentially subject the Company to significant concentrations of credit risk consists principally of trade accounts receivable and cash equivalents.
The Company performs credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary, but generally requires no collateral. Credit quality is monitored regularly by reviewing credit history. The Company believes that the concentration of credit risk in its trade accounts receivables is moderated by its credit evaluation process, relatively short collection terms, the high level of credit worthiness of its customers, and letters of credit issued on the Company’s behalf. Potential credit losses are limited to the gross value of accounts receivable.
Inventories—Inventories are stated at the lower of cost (first-in, first-out) or net realizable value. The Company reviews the components of its inventory periodically for excess, obsolete and impaired inventory and records a reduction to the carrying value when identified.
Property, Plant and Equipment—Property, plant and equipment is recorded at cost and depreciated over the estimated useful lives of the assets (three to fifteen years) using the straight-line method. Amortization of leasehold improvements is computed on the straight-line method over the shorter of the lease term or the estimated useful lives of the related assets.
Goodwill and Intangible Assets—Intangible assets are recorded at cost and amortized on a straight-line basis over their estimated useful lives, except for indefinite-lived intangibles such as goodwill. Software development costs associated with software to be leased or otherwise marketed are expensed as incurred until technological feasibility has been established. After technological feasibility is established, software development costs are capitalized and amortized on a straight-line basis over the estimated product life.
Convertible Debt—The Company accounts for convertible debt instruments that may be settled in cash upon conversion (including combination settlement of cash equal to the “principal portion” and delivery of the “share amount” in excess of the conversion value over the principal portion in shares of common stock and/or cash) by separating the liability and equity components of the instruments in a manner that reflects our nonconvertible debt borrowing rate. The Company determines the carrying amount of the liability component by measuring the fair value of similar debt instruments that do not have the conversion feature. If no similar debt instrument exists, the Company estimates fair value by using assumptions that market participants would use in pricing a debt instrument, including market interest rates, credit standing, yield curves and volatilities.
54


Determining the fair value of the debt component requires the use of accounting estimates and assumptions. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component, and the associated non-cash interest expense. See Note 3 for additional discussion of the Convertible Senior Notes issued in December 2014.
Revenue Recognition—The Company records revenues primarily from product sales. These revenues are recorded net of rebates and other discounts. These rebates and discounts are estimated at the time of sale, and are largely driven by various customer program offerings, including special pricing agreements, promotions and other volume-based incentives. Rebates and discounts are calculated based upon historical experience, estimated discounting levels and estimated distributor inventory balances and recorded as a reduction of sales with offsets to accounts receivable and other current liabilities, respectively.
Revenue is recognized when control of the products is transferred to the customers in an amount that reflects the consideration the Company expects to receive from the customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract and the contract price, allocating the contract price to the distinct performance obligations in the contract and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. A performance obligation is considered to be satisfied once the control of a product is transferred to the customer or the service is provided to the customer, meaning the customer has the ability to use and obtain the benefit of the goods or service.
A portion of product sales includes revenues for diagnostic kits, which are utilized on leased instrument systems under the Company’s “reagent rental” program. The reagent rental program provides customers the right to use the instruments at no separate cost to the customer in consideration for a multi-year agreement to purchase annual minimum amounts of consumables (“reagents” or “diagnostic kits”). When an instrument is placed with a customer under a reagent rental agreement, the Company retains title to the equipment and it remains capitalized on the Company’s Consolidated Balance Sheets as property, plant and equipment, net. The instrument is depreciated on a straight-line basis over the lesser of the lease term or life of the instrument. Depreciation expense is recorded in cost of sales included in the Consolidated Statements of Income. Instrument and consumables under the reagent rental agreements are deemed two distinct performance obligations. Though the instrument and consumables do not have any use to customers without one another, they are not highly interdependent because they do not significantly affect each other. The Company would be able to fulfill its promise to transfer the instrument even if its customers did not purchase any consumables and the Company would be able to fulfill its promise to provide the consumables even if customers acquired instruments separately. The contract price is allocated between these two performance obligations based on the relative standalone selling prices. The instrument is considered an operating lease and revenue allocated to the instrument will be separately disclosed, if material.
Government Assistance— During the year ended December 31, 2020, the Company entered into a contract with the National Institute of Health (“NIH”), through its newly launched Rapid Acceleration of Diagnostics - Advanced Technology Platforms initiative, to support the Company’s expansion of its manufacturing capacity for its diagnostic assays that test for the SARS-CoV-2 antigen. The contract provides for consideration to the Company of up to $65.0 million and has a performance period of one year, which began in July 2020. The contract includes key deliverables and milestones that will directly support the upgrade and addition of new manufacturing lines as well as the outfitting of a new distribution center. The Company will also provide instruments and assays to NIH. There are no refund provisions under the contract.
Consideration from the contract is allocated to each deliverable identified within the contract using a relative fair value allocation method and recognized when there is reasonable assurance the Company will meet the milestones and receive the consideration. Consideration allocated to the delivery of instruments and assays are recognized in accordance with the Company’s existing revenue recognition policy described above. Consideration that relates to capital expenditures is recorded as a reduction to the carrying value of such assets and amortized over the useful life of the assets. Consideration allocated to the remainder of the contract is recorded as reductions to the related expense. During the year ended December 31, 2020, the Company incurred $15.9 million in capital expenditures, which will be reimbursed under this contract as future milestones are met. Therefore, the Company accrued such unbilled receivables in prepaid expenses and other current assets as of December 31, 2020.
Research and Development Costs—Research and development costs are charged to operations as incurred. In conjunction with certain third-party service agreements, the Company is required to make periodic payments based on achievement of certain milestones. The costs related to these research and development services are also charged to operations as incurred.
55


Product Shipment Costs—Product shipment costs are included in sales and marketing expense in the accompanying Consolidated Statements of Income. Shipping and handling costs were $14.2 million, $9.5 million and $8.3 million for the years ended December 31, 2020, 2019 and 2018, respectively.
Advertising Costs—Advertising costs are expensed as incurred. Advertising costs were $1.1 million, $1.3 million and $0.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.
Income Taxes—Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. The Company’s policy is to recognize the interest expense and penalties related to income tax matters as a component of the income tax provision.
Fair Value of Financial Instruments— The Company uses the fair value hierarchy established in Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, which requires that the valuation of assets and liabilities subject to fair value measurements be classified and disclosed by the Company in one of the following three categories:
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).
The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivables, accounts payable and accrued liabilities approximate their fair values due to their short-term nature.
Stock-Based Compensation—Compensation expense related to stock options granted is recognized ratably over the service vesting period for the entire option. For stock options with graded vesting, the Company ensures that the cumulative amount of compensation expense recognized at the end of any reporting period at least equals the portion of the stock option that has vested at that date. The total number of stock options expected to vest is adjusted by estimated forfeiture rates. The Company determined the estimated fair value of each stock option on the date of grant using the Black-Scholes option valuation model. The fair value of restricted stock units is determined based on the closing market price of the Company’s common stock on the grant date. Compensation expense for time-based restricted stock units (“RSUs”) is measured at the grant date and recognized ratably over the vesting period. A portion of the restricted stock granted are performance-based and vesting is tied to achievement of specific Company goals over a three-year time period, subject to early vesting upon achievement of the performance goals. For purposes of measuring compensation expense for performance-based restricted stock units (“PSUs”), the number of shares ultimately expected to vest is estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. The grant date of the PSUs takes place when the grant is authorized and the specific achievement goals are communicated.
Comprehensive Income—Comprehensive income includes unrealized gains and losses which are related to the cumulative translation adjustments and derivative instruments excluded from the Company’s Consolidated Statements of Income.
Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Accounting Periods—Each of the Company’s fiscal quarters end on the Sunday closest to the end of the calendar quarter. The Company’s fiscal year ended January 3, 2021 was 53 weeks and the Company’s fiscal years ended December 29, 2019 and December 30, 2018 were 52 weeks. For ease of reference, the calendar year end dates are used herein.
Leases—Lease liabilities represent the obligation to make lease payments and right-of-use (“ROU”) assets represent the right to use the underlying asset during the lease term. Lease liabilities and ROU assets are recognized at the commencement date of the lease based on the present value of lease payments over the lease term at the commencement date. When the implicit rate is unknown, an incremental borrowing rate based on the information available at the commencement date is used in
56


determining the present value of the lease payments. Options to extend or terminate the lease are included in the determination of the lease term when it is reasonably certain that the Company will exercise such options.
For certain classes of assets, the Company accounts for lease and non-lease components as a single lease component. Variable lease payments, including those related to changes in the consumer price index, are recognized in the period in which the obligation for those payments are incurred and are not included in the measurement of the ROU assets or lease liabilities. Short-term leases are excluded from the calculation of the ROU assets and lease liabilities.
Operating leases are included in right-of-use assets, operating lease liabilities and operating lease liabilities non-current in the Consolidated Balance Sheet. Finance leases are included in property, plant and equipment, net, other current liabilities and other non-current liabilities.

Note 3. Debt
Convertible Senior Notes
In December 2014, the Company issued $172.5 million aggregate principal amount of 3.25% Convertible Senior Notes due 2020. The Company accounted separately for the liability and equity components of the Convertible Senior Notes in
58


accordance with authoritative guidance for convertible debt instruments that may be settled in cash upon conversion. The guidance required the carrying amount of the liability component to be estimated by measuring the fair value of a similar liability that does not have an associated conversion feature. Because the Company had no outstanding non-convertible public debt, the Company determined that senior, unsecured corporate bonds traded on the market represent a similar liability to the Convertible Senior Notes without the conversion option. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in the same industry with similar credit ratings and with similar maturity, the Company estimated the implied interest rate of its Convertible Senior Notes to be 6.9%, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component, which were defined as Level 2 observable inputs. The estimated implied interest rate was applied to the Convertible Senior Notes, which resulted in a fair value of the liability component of $141.9 million upon issuance, calculated as the present value of implied future payments based on the $172.5 million aggregate principal amount. The $30.7 million difference between the cash proceeds of $172.5 million and the estimated fair value of the liability component was recorded in additional paid-in capital, net of tax and issuance costs, as the Convertible Senior Notes were not considered redeemable. During 2020 the remaining aggregate principal amount of Convertible Senior Notes were settled or matured on December 15, 2020 and at December 31, 2020 no amounts were outstanding.
The following table summarizes the amount of interest expense for the following periods (in thousands):

Revolving Credit Facility
On August 31, 2018, the Company entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) which provides the Company with a $175.0 million Revolving Credit Facility. The Company repaid the remaining principal during the year ended December 31, 2019 and no balance remained outstanding as of December 31, 2020. The Credit Agreement has a term of five years and matures on August 31, 2023.
Loans will bear interest at a rate equal to (i) the London Interbank Offered Rate (“LIBOR”) plus the “applicable rate” or (ii) the “base rate” (defined as the highest of (a) the Bank of America prime rate, (b) the Federal Funds rate plus one-half of one percent and (c) LIBOR plus one percent) plus the “applicable rate.” The applicable rate is determined in accordance with a pricing grid based on the Company’s Consolidated Leverage Ratio (as defined in the Credit Agreement) ranging from 1.75% to 2.50% per annum for LIBOR rate loans and from 0.75% to 1.50% per annum for base rate loans. In addition, the Company pays a commitment fee on the unused portion of the Credit Agreement based on the Company’s Consolidated Leverage Ratio ranging from 0.15% to 0.30% per annum.
The Revolving Credit Facility is guaranteed by certain material domestic subsidiaries of the Company (the “Guarantors”) and is secured by liens on substantially all of the assets of the Company and the Guarantors, excluding real property and certain other types of excluded assets, and contains affirmative and negative covenants that are customary for credit agreements of this nature. The negative covenants include, among other things, limitations on asset sales, mergers, indebtedness, liens, dividends and other distributions, investments and transactions with affiliates. The Credit Agreement contains two financial covenants: (i) maximum Consolidated Leverage Ratio (as defined in the Credit Agreement) as of the last day of each fiscal quarter of 3.50 to 1.00, which ratio may be increased to 4.50 to 1.00 in case of certain qualifying acquisitions; and (ii) a minimum Consolidated Fixed Charge Coverage Ratio (as defined in the Credit Agreement) of 1.25 to 1.00 as of the end of any fiscal quarter for the most recently completed four fiscal quarters. The Company was in compliance with all financial covenants as of December 31, 2020.

Interest expense recognized on the Credit Agreement including amortization of deferred issuance cost was $0.7 million, $1.7 million, and $6.5 million, respectively, for the years ended December 31, 2020, 2019 and 2018.

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. For the three years ended December 31, 2020, the Company has demonstrated positive cumulative pre-tax book income. Such objective positive evidence allowed the Company to consider other subjective evidence, such as the Company’s projections for future profitability, to determine the realizability of its deferred tax assets. On the basis of this evaluation, during the year ended December 31, 2020, the Company decreased the valuation allowance by $0.1 million related to the U.S. Foreign Tax Credit.
The valuation allowance of $2.3 million as of December 31, 2020 represents the portion of the deferred tax asset that management could not conclude was more likely than not to be realized. The amount of the deferred tax assets considered realizable could be adjusted in the future based on changes in available positive and negative evidence.
As of December 31, 2020, the Company had no federal net operating loss (“NOL”) carryforwards. The Company had state NOLs of approximately $5.9 million which will begin to expire in 2030 unless previously utilized. The Company has no federal research credits. The Company has federal foreign tax credits of $2.3 million which will begin to expire on December 31, 2028 unless previously utilized. The Company has state research credits of $12.3 million, of which none expire.
Pursuant to Internal Revenue Code Sections 382 and 383, the Company’s use of its NOL and tax credit carryforwards may be limited as a result of cumulative changes in ownership of more than 50% over a three-year period. As of December 31, 2020, the Company does not believe any historical ownership change has limited the use of its NOLs or tax credit carryforwards.

The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believes that it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcome of examinations by tax authorities in determining the adequacy of its provision for income taxes.

As of December 31, 2020, 2019 and 2018, the Company had unrecognized tax benefits of $22.6 million, $17.2 million, and $15.2 million respectively, of which $15.0 million and $11.1 million and $9.3 million, respectively, would reduce the Company’s annual effective tax rate, if recognized. It is reasonably possible that the amount of unrecognized tax benefits in various jurisdictions may decrease in the next 12 months due to settlements with tax authorities. However, due to the uncertainty surrounding the timing of these events, an estimate in the change within the next 12 months cannot be made at this time. The Company’s policy is to recognize the interest expense and penalties related to income tax matters as a component of the income tax expense. The Company had accrued interest and penalties associated with uncertain tax positions of $0.5 million as of December 31, 2020, $0.4 million as of December 31, 2019 and $0.3 million as of December 31, 2018. Interest expense, net of accrued interest (reversed), was approximately $0.1 million for the years ended December 31, 2020, 2019 and 2018.
The Company is subject to periodic audits by domestic and foreign tax authorities.
As of December 31, 2020, the Company no longer has any federal net operating loss or credit carryforwards. However, because of utilization of tax attributes generated in tax years 2012 and later on its tax returns still open by statute, the Company’s federal tax years from 2012 and forward are still subject to examination by tax authorities. Due to the carryforward of unutilized California net operating losses and credits, the Company’s California tax returns for years 2001 and forward are subject to examination by tax authorities. The Company believes that it has appropriate support for the income tax positions taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors, including past experience and interpretations of tax law applied to the facts of each matter.
The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020. The CARES Act provides for, among other things, refundable payroll tax credits, deferment of employer side social security payments and technical amendments regarding the income tax depreciation of qualified improvement property placed in service after December 31, 2017. The Company is benefiting only from the technical amendments regarding retroactive accelerated income tax depreciation on certain of our leasehold improvement assets.
Note 5. Stockholders’ Equity
Preferred Stock. The Company’s certificate of incorporation, as amended, authorizes the issuance of up to 5 million preferred shares. The Board of Directors is authorized to fix the number of shares of any series of preferred stock and to determine the designation of such shares. However, the amended certificate of incorporation specifies the initial series and the rights of that series. No shares of preferred stock were outstanding as of December 31, 2020, 2019 or 2018.
Equity Incentive Plan. The Company grants stock options, RSUs and PSUs to employees and non-employee directors under its 2018 Equity Incentive Plan (the “2018 Plan”). The Company previously granted stock options under its 2016 Equity Incentive Plan (the “2016 Plan”), Amended and Restated 2010 Equity Incentive Plan (the “2010 Plan”) and the Amended and Restated 2001 Equity Incentive Plan (the “2001 Plan”). The 2016 Plan, 2010 Plan and 2001 Plan were terminated at the time of adoption of the 2018 Plan, but the terminated Plans continue to govern outstanding options granted thereunder. The Company has stock options, RSUs and PSUs outstanding, which were issued under each of these equity incentive plans to certain employees and directors. Stock options granted under these plans have terms ranging up to ten years, have exercise prices ranging from $14.56 to $248.41 per share, and generally vest over four years. As of December 31, 2020, approximately 2.2 million shares remained available for grant and 3.8 million shares of common stock were reserved for future issuance under the 2018 Plan.
Restricted Stock Units. The Company grants both RSUs and PSUs to certain officers, directors and management. Until the restrictions lapse, ownership of the affected restricted stock units granted to the Company’s officers, directors and management is conditional upon continuous employment with the Company.
For the years ended December 31, 2020, 2019 and 2018, the Company granted approximately 0.2 million, 0.3 million and 0.2 million shares, respectively, of RSUs to Board of Directors, officers and management, which either have a time-based four-year vesting provision or performance-based vesting provisions.
During the years ended December 31, 2020, 2019 and 2018, RSUs were granted to certain members of the Board of Directors in lieu of cash compensation as a part of the Company’s non-employee director’s deferred compensation program. The compensation expense associated with these RSU grants were $0.5 million, $0.5 million and $0.4 million for the years ended December 31, 2020, 2019 and 2018, respectively.
Employee Deferred Bonus Compensation Program. For the years ended December 31, 2020, 2019 and 2018, certain employees of the Company were eligible to participate in the Company’s deferred bonus compensation program with respect to any payments received under the Company’s cash incentive plan. Participating employees could elect to receive 50% or 100%
62


of the cash value of their cash bonus in the form of fully vested RSUs plus a premium as additional RSUs, issued under the 2018 Plan. The premium RSUs are subject to a one-year vesting requirement from the date of issuance. The additional premium will be determined based on the length of time of the deferral period selected by the participating employee as follows: (i) if one year from the date of grant, a premium of 10% on the amount deferred, (ii) if two years from the date of grant, a premium of 20% on the amount deferred, or (iii) if four years from the date of grant, a premium of 30% on the amount deferred.
Employee Stock Purchase Plan. Under the Company’s Amended and Restated 1983 Employee Stock Purchase Plan (the “ESPP”), full-time employees are allowed to purchase common stock through payroll deductions (which cannot exceed 10% of the employee’s compensation) at the lower of 85% of fair market value at the beginning or end of each six-month purchase period. As of December 31, 2020, 86,571 shares remained available for future issuance.
Share Repurchase Program. On December 12, 2018, the Board of Directors authorized a stock repurchase program pursuant to which up to $50.0 million of the Company’s shares of common stock may be purchased through December 12, 2020. On August 28, 2020, the Board authorized an increase of additional $150.0 million to the Company’s existing stock repurchase program and also extended the repurchase authorization through August 28, 2022. During the year ended December 31, 2020, 257,329 shares of outstanding common stock were repurchased under the revised share repurchase program. There were no repurchases during 2019. At December 31, 2020, $156.3 million remained available under the new repurchase program.

Total stock-based compensation expense$21,019 $13,252 $11,709 
For the years ended December 31, 2020, 2019 and 2018, the Company recorded $2.2 million, $1.4 million and $1.6 million in stock-based compensation expense, respectively, associated with the deferred bonus compensation program, described in Note 5. During the years ended December 31, 2020, 2019 and 2018, $2.1 million, $0.8 million and $1.6 million, respectively, was initially recorded as a component of accrued payroll and related expenses associated with the deferred bonus compensation program.
Stock Options
Compensation expense related to stock options granted is recognized ratably over the service vesting period for the entire option award. The estimated fair value of each stock option was determined on the date of grant using the Black-Scholes option valuation model with the following weighted-average assumptions:
Year ended December 31,
 202020192018
Risk-free interest rate1.18 %2.51 %2.49 %
Expected option life (in years)5.125.686.29
Volatility rate41 %39 %36 %
Dividend rate0 %0 %0 %
The computation of the expected option life is based on a weighted-average calculation combining the average life of options that have already been exercised and post-vest cancellations with the estimated life of the remaining vested and unexercised options. The expected volatility is based on the historical volatility of the Company’s stock. The risk-free interest rate is based on the U.S. Treasury yield curve over the expected term of the option. The Company has never paid any cash dividends on its common stock, and does not anticipate paying any cash dividends in the foreseeable future. Consequently, the Company uses an expected dividend yield of zero in the Black-Scholes option valuation model. The Company’s estimated forfeiture rate is based on its historical experience and future expectations.
63



The Company’s determination of fair value is affected by the Company’s stock price as well as a number of assumptions that require judgment. The weighted-average fair value per share was $36.84, $23.67 and $18.76 for options granted during the years ended December 31, 2020, 2019 and 2018, respectively. The total intrinsic value was $51.8 million, $49.8 million and $38.2 million for options exercised during the years ended December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, total unrecognized compensation expense related to stock options was approximately $7.1 million and the related weighted-average period over which it is expected to be recognized is approximately 2.0 years. The maximum contractual term of the Company’s stock options is ten years.

The total amount of unrecognized compensation expense related to non-vested restricted stock units as of December 31, 2020 was approximately $25.2 million, which is expected to be recognized over a weighted-average period of approximately 1.4 years.
Note 7. Earnings Per Share
Basic earnings per share (“EPS”) is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted EPS is computed based on the sum of the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of shares issuable from stock options, unvested RSUs and the 3.25% Convertible Senior Notes. Potentially dilutive common shares from outstanding stock options and unvested RSUs are determined using the average share price for each period under the treasury stock method.
Potentially dilutive shares from the Convertible Senior Notes are determined using the if-converted method. Under the provisions of the if-converted method, the Convertible Senior Notes are assumed to be converted and the resulting common shares are included in the denominator of the EPS calculation and the interest expense, net of tax, recorded in connection with the Convertible Senior Notes is added back to net income. The Convertible Senior Notes have a dilutive impact when the average market price of the Company’s common stock exceeds the applicable conversion price of the notes. The Convertible Senior Notes became convertible on March 31, 2018 and matured on December 15, 2020.
The following table reconciles net income and the weighted-average shares used in computing basic and diluted EPS in the respective periods (in thousands):

Summers Ridge Lease — The Company leases three of the four buildings that are located on the Summers Ridge Property in San Diego, California with an initial term through January 2033 with options to extend the lease for two additional five-year terms upon satisfaction of certain conditions, which have not been included in the determination of the lease term. The lease is subject to must-take provisions related to one additional building, which will have the same lease term as the three buildings originally leased. The remaining building is subject to the expiration of the lease with its current tenant for which the expiration date is not yet known.
McKellar Lease — During 1999, the Company completed a sale and leaseback transaction of its San Diego facility at McKellar Court to a partnership for which the Company is a 25% limited partner. The partnership is deemed to be a variable interest entity (VIE). The Company is not, however, the primary beneficiary of the VIE as it does not have the power to direct the activities of the partnership and does not have the obligation to absorb losses or receive benefits of the partnership that could potentially be significant to the partnership. The Company made lease payments to the partnership of approximately $1.0 million, $1.0 million and $0.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Rutherford Lease — During January 2021, the Company entered into a lease agreement for a manufacturing facility in Carlsbad, California. The minimum lease payments related to the lease is approximately $70.5 million. The initial lease term is 15 years with options to extend the lease for two additional five-year periods.
Purchase Commitments
The Company has $32.1 million in firm inventory purchase commitments as of December 31, 2020, the majority of which will be purchased within the next twelve months.
Litigation and Other Legal Proceedings
In Beckman Coulter Inc. v. Quidel Corporation, which was filed in the Superior Court for the County of San Diego, California, on November 27, 2017, Beckman Coulter (“Beckman”) alleges that a provision of an agreement between Quidel and Beckman violates state antitrust laws. Our acquisition of the B-type Naturietic Peptide assay business (“BNP Business”) consisted of assets and liabilities relating to a contractual arrangement with Beckman (the “Beckman Agreement”) for the supply of antibodies and other inputs related to, and distribution of, the Triage® BNP Test for the Beckman Coulter Access Family of Immunoassay Systems. The Beckman Agreement further provides that Beckman, for a specified period, cannot research, develop, manufacture or sell an assay for use in the diagnosis of cardiac diseases that measures or detects the presence or absence of BNP or NT-pro-BNP (a related biomarker) (the “Exclusivity Provision”). In the lawsuit, Beckman asserts that this provision violates certain state antitrust laws and is unenforceable. Beckman contends that it has suffered damages due to this provision and seeks a declaration that this provision is void.
On December 7, 2018, the trial court granted a motion by Beckman for summary adjudication, holding that the Exclusivity Provision is void under California law (the “December 7 Order”). On December 18, 2018, the trial court stayed the effect of the December 7 Order pending a decision on a writ petition Quidel intended to file with the Court of Appeal. Quidel filed its writ petition on January 18, 2019, asking the Court of Appeal to review and reverse the December 7 Order. On February 7, 2019, the trial court stayed all the remaining litigation pending the outcome of the writ petition and vacated all deadlines in the case.
On March 14, 2019, the Court of Appeal issued an order to show cause why the relief sought in Quidel’s petition should not be granted. The Court also stayed the December 7 Order pending a further order from the Court of Appeal. On August 29, 2019, the Court of Appeal issued a written decision ruling in Quidel’s favor and overturning the December 7 Order. Beckman challenged the Court of Appeal’s ruling with a petition for rehearing on September 10, 2019, which was denied on September 13, 2019.
On October 1, 2019, Beckman filed a petition for review of the Court of Appeal’s ruling with the Supreme Court of California (the “Supreme Court”). We subsequently filed an answer to Beckman’s petition, Beckman filed a response to our reply and on November 13, 2019, the Supreme Court granted review of the Court of Appeal ruling, with further action in this matter being deferred pending consideration and disposition of a related issue in Ixchel Pharma v. Biogen, or pending further order of the Supreme Court.
On August 3, 2020, the Supreme Court issued its opinion in Ixchel Pharma v. Biogen, holding, among other matters, that in evaluating whether a restraint in a business-to-business agreement violates California law, “a rule of reason applies to determine the validity of a contractual provision by which a business is restrained from engaging in a lawful trade or business with another business.” That is, the Supreme Court rejected the position that every contract in restraint of trade in the business context is per se void, but rather each must be evaluated based on a rule of reason.
On September 9, 2020, the Supreme Court transferred the matter back to the Court of Appeal with directions to vacate its decision and reconsider the case in light of the Supreme Court’s Ixchel Pharma v. Biogen ruling.
On November 6, 2020, the Court of Appeal issued its opinion, granting our petition and directing the trial court to vacate its December 7, 2018 order granting Beckman’s motion for summary adjudication.
On January 20, 2021, the Court of Appeal issued a remittitur, certifying its November 6, 2020 opinion and transferring the case back to the trial court where the litigation will continue and the exclusivity provision will be evaluated under a rule of reason analysis under California law.
The stay remains in place at the trial court level and a status conference is scheduled for March 12, 2021.

Quidel denies that the Exclusivity Provision is unlawful, denies any liability with respect to this matter, and intends to vigorously defend itself. There are multiple factors that prevent us from being able to estimate the amount of loss, if any, that may result from this matter including: (1) we are vigorously defending ourselves and believe that we have a number of meritorious legal defenses; (2) there are unresolved questions of law and fact that could be important to the ultimate resolution of this matter, some of which are subject to review by the Supreme Court; and (3) discovery is ongoing. Accordingly, at this time, we are not able to estimate a possible loss or range of loss that may result from this matter or to determine whether such loss, if any, would have a material adverse effect on our financial condition, results of operations or liquidity.
From time to time, the Company is involved in other litigation and proceedings, including matters related to product liability claims, commercial disputes and intellectual property claims, as well as regulatory, employment, and other claims related to our business. The Company accrues for legal claims when, and to the extent that, amounts associated with the claims become probable and are reasonably estimable. The actual costs of resolving legal claims may be substantially higher or lower than the amounts accrued for those claims. For those matters as to which we are not able to estimate a possible loss or range of loss, we are not able to determine whether the loss will have a material adverse effect on our business, financial condition or results of operations or liquidity. No accrual has been recorded as of December 31, 2020 and December 31, 2019 related to such matters as they are not probable and/or reasonably estimable. 
Management believes that all such current legal actions, in the aggregate, will not have a material adverse effect on the Company. However, the resolution of, or increase in any accruals for, one or more matters may have a material adverse effect on the Company’s results of operations and cash flows. The Company also maintains insurance, including coverage for product liability claims, in amounts that management believes are appropriate given the nature of its business.
Licensing Arrangements
The Company has entered into various licensing and royalty agreements, which largely require payments by the Company based on specified product sales as well as the achievement of specified milestones. The Company had royalty and license expenses relating to those agreements of approximately $2.4 million, $1.1 million and $0.4 million for the years ended December 31, 2020, 2019 and 2018, respectively.
Note 9. Segment, Revenue and Geographic Information
The Company operates in one reportable segment. Sales to customers outside the U.S. represented 13%, 33% and 32% of total revenue for the years ended December 31, 2020, 2019 and 2018, respectively, of which sales to customers in China comprised 4%, 13% and 10%, respectively. As of December 31, 2020 and 2019, net accounts receivable due from foreign customers were $18.6 million and $22.9 million, respectively. For the year ended December 31, 2020, sales of our coronavirus products accounted for 70% of total revenue. For the years ended December 31, 2020, 2019 and 2018, sales of our influenza products accounted for 8%, 26%, and 24% respectively, of total revenue.
The Company had sales to individual customers in excess of 10% of total revenue, as follows:

Note 10. Fair Value Measurement
The following table presents the Company’s hierarchy for its assets and liabilities measured at fair value on a recurring basis as of the following periods (in thousands):

Total liabilities measured at fair value$ $119,012 $11,896 $130,908 $ $151,815 $16,535 $168,350 
There were no transfers of assets or liabilities between Level 1, Level 2, and Level 3 categories of the fair value hierarchy during the years ended December 31, 2020 and 2019.
Cash equivalents consistent of funds held in money market accounts that are valued using quoted prices in active markets for identical instruments. Derivative financial instruments are based on observable inputs that are corroborated by market data. Observable inputs include broker quotes and daily market foreign currency rates and forward pricing curves. 
In connection with the acquisition of the BNP Business, the Company pays annual installments of $42.0 million each in deferred consideration through April 2023 and up to $8.0 million each in contingent consideration through April 2022. The fair value of the deferred consideration is calculated based on the net present value of cash payments using an estimated borrowing rate based on a quoted price for a similar liability. The fair value of contingent consideration is calculated using a discounted probability weighted valuation model. Discount rates used in such calculation is a significant assumption that is not observed in the market and, therefore, the resulting fair value represents a Level 3 measurement.
69



The Company assesses the fair value of contingent consideration to be settled in cash related to these prior acquisitions using a discounted revenue model. Significant assumptions used in the measurement include revenue projections and discount rates. This fair value measurement of contingent consideration is based on significant inputs not observed in the market and thus represent Level 3 measurements. The changes in fair value of the contingent considerations during the years ended 2020, 2019 and 2018 were due to changes in the estimated payments and discounting periods.
Changes in estimated fair value of contingent consideration liabilities from December 31, 2017 through December 31, 2020 are as follows (in thousands):
 Contingent consideration
liability
(Level 3 measurement)
Balance at December 31, 2017$24,301

Change in estimated fair value, recorded in general and administrative expenses1,405 
Balance at December 31, 2020$11,896 

Note 11. Employee Benefit Plan
The Company has a defined contribution 401(k) plan (the “401(k) Plan”) covering all employees who are eligible to join the 401(k) Plan upon employment. Employee contributions are subject to a maximum limit by federal law. This Plan includes an employer match of 50% on the first 6% of pay contributed by the employee. The Company contributed approximately $3.1 million, $2.5 million and $2.6 million to the 401(k) Plan during the years ended December 31, 2020, 2019 and 2018, respectively.
Note 12. Foreign Currency Hedges
In the normal course of business, the Company is exposed to gains and losses resulting from fluctuations in foreign currency exchange rates. As part of its strategy to manage the level of exposure to the risk of fluctuations in foreign currency exchange rates, the Company uses designated cash flow hedges in the form of foreign currency forward contracts to mitigate the impact of foreign currency translation on transactions that are denominated primarily in the Euro and the Chinese Yuan. The Company also uses non-designated forward contracts to hedge non-functional currency denominated balance sheet assets. Hedging relationships for all derivative hedges and the underlying hedged items, as well as the risk management objectives and strategies for undertaking the hedge transactions are formally documented. The Company does not use any derivative financial instruments for trading or other speculative purposes.
Such forward foreign currency contracts are carried at fair value in prepaid expenses and other current assets or other current liabilities depending on the unrealized gain or loss position of the hedged contract as of the balance sheet date. Changes in the value of the derivatives are recorded to other comprehensive income (loss) until the underlying hedged item is recognized in earnings, or the derivative no longer qualifies as a highly effective hedge. The cash flows from derivatives treated as hedges are classified in the Consolidated Statements of Cash Flows in the same category as the item being hedged.
The notional principal amounts for outstanding derivative instruments provide one measure of the transaction volume outstanding and do not represent the amount of our exposure to credit or market loss. Credit risk represents our gross exposure to potential accounting loss on derivative instruments that are outstanding or unsettled if all counterparties failed to perform according to the terms of the contract, based on then-current currency exchange rates at each respective date. We generally enter into master netting arrangements, which reduces credit risk by permitting net settlement of transactions with the same counterparty. We present our derivative assets and derivative liabilities at their net fair values. We did not have any derivative instruments with credit-risk related contingent features that would require us to post collateral.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure
None.
Item 9A. Controls and Procedures
Evaluation of disclosure controls and procedures: We have performed an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”). Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of December 31, 2020 at a reasonable assurance level to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Changes in internal control over financial reporting: There was no change in our internal control over financial reporting during the quarter ended December 31, 2020 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
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 Rule 13a-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013), 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, 2020.
The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by Ernst & Young LLP, our independent registered public accounting firm, as stated in their report which is included in this Item 9A.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Quidel Corporation
Opinion on Internal Control over Financial Reporting
We have audited Quidel Corporation’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), (the COSO criteria). In our opinion, Quidel Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related notes and schedule listed in the Index at Item 15(a)(2) and our report dated February 18, 2021 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
