Research and development expenses were approximately $95.7 million, $84.3 million, and $52.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. We anticipate that we will continue to devote a significant amount of financial resources to product and technology research and development in the foreseeable future. t Marketing and Distribution Our current business strategy is designed to serve the continuum of healthcare delivery needs globally, starting with POC a ories in North America and a variety of settings internationally. We are also increasingly prioritizing retail and clinicians located in doctor’s office practices, to moderately complex POLs, and to highly complex hospital and clinical reference laborat online outlets, such as large pharmacies, to market and distribute our QuickVue At-Home OTC COVID-19 tests. Within the inherent operational diversity of these various segments, we focus on differentiating ourselves and enhancing our market leadership by specializing in the diagnosis and monitoring of select disease states, conditions and wellness categories. 12 Our marketing strategy includes ensuring that our key product portfolios are supported by clinical validation and health economic and outcomes research that demonstrate 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 highly fragmented POC market, with many small or medium-sized customers. To reach customers using POC diagnostic tests, a network of national and regional distributors is employed, as well as our own sales force. We have expanded the size of our North America sales force in the past few years. As of December 31, 2021, we employed approximatelyy 125 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 culturet a tory end-users in tories using these diagnostic tests through our own direct sales force and technical support tests are controlled primarily by us. We reach labora hospitals and clinical reference labora services that have specialized training and understanding of this product portfolio. a We sell products globally and market and distribute products worldwide in a variety of ways, including a mix of direct sales and marketing and indirect distribution strategies. In Europe, we currently employ approximately 95 employees to support 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 60 employees in China and approximately 25 employees in India, primarily to support sales and marketing efforts for the Triage and BNP Businesses and to grow our core immunoassay and cell culturet created a shared service center in Shanghai, China to support general and administrative, technical support and customer service functions in China. businesses.

We also face competition from our distributors since some have created, and others may decide to create, their own products to competm e 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. a Seasonality Sales of our respiratory products are subjeu ct 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 and 2021. Historically, sales of our influeff 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, 2021, 2020 and 2019, sales of our influenza products accounted for 4%, 8% and 26%, 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. nza products have varied from year to year Government Regulations tt US Regulatll ions of Medical Devices The testing, manufacture and commercialization of our products in the US are subject to regulation by numerous governmental authorities, principally the FDA and corresponding state regulatory agencies.

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 labora In addition, modifications or enhancements for existing products that could significantly affecff constitute a majora change in the intended use of the device, will require new submissions to the FDA. a t their safetyt or effectiveness or tory studies.

These requirements vary by jurisdiction, differ from those in the US, 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 varies from that required for FDA clearance or approval. In many foreign countries, pricing and reimbursement approvals are also required. 15 Our initial focus for obtaining marketing approval outside the US is typically in the European Union (“EU”), Australia, Brazil, Canada, China, and Japan. EU regulations and directives generally classify healthcare products either as medicinal products, medical devices or IVD. The CE Mark certification for the EU requires us to receive certification from ISO for the manufacture of our products. This certification comes only afteff r 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 that attests to the product’s compliance to Regulation Directive 98/79/EC for IVD 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 than in the US, including in the area of clinical evaluation requirements, quality systems and post-market surveillance. The compliance deadline for the EU MDR was May 2021. Manufacturers of currently approved medical devices will have until May 2022 to meet the EU IVDR, unless an extension has been granted. Complying with these regulations may require us to incur significant expenditures. regulatory requirements could adversely impact our business in the EU and other regions that tie their product registrations to the EU requirements. Failure to meet these t 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.

Among other things, these laws and others generally (a) prohibit the provision of anything of value in exchange for the referral of patients or for the purchase, order, or recommendation of any item or service reimbursed by a federal healthcare program, including Medicare and Medicaid; (b) require that claims for payment submitted to federal healthcare programs be truthful; and (C) require the maintenance of certain government licenses and permits. 16 Datatt Privacy and Securitytt Laws We are subject to data privacy and security laws and regulations in numerous jurisdictions, as well as customer-imposed health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by controls, as a result of having access to and processing confidential, personal and/or sensitive data in the course of our business. US federal and state laws protect the confidentiality of certain health-related and other personal information, in particular personally identifiable information such as medical records, and restrict the collection, use and disclosure of that protected information. At the federal level, the HHS promulgates health information privacy and security rules under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which protect health information by regulating its use and disclosure. Although we are not directly subject to HIPAA other than with respect to providing certain employee benefits, we could potentially be subject to criminal penalties if we, our affiliates, or our agents knowingly obtain, use, or disclose personally identifiablea HIPAA. In addition to HIPAA, individual states also regulate data breach and security requirements and multiple governmental bodies assert authority over aspects of the protection of personal privacy. For examplem , a broad privacy law in California, the Californi ff GDPR (discussed below) such as certain requirements for data collection, use and sharing practices and certain rights of consumers concerning the use, disclosure, and retention of their personal data. The CCPA has already prompted several other states to follow with similar laws. The EU General Data Protection Regulation that became effecff tive in May 2018 (“GDPR”) has imposed significantly stricter requirements in how we collect, transmit, process and retain personal data, including, among m other things, in certain circumstances a requirement for almost immediate notice of data breaches to supervisory authorities and prompt notice to data subjects with significant fines for non-compliance. Several other countries such as China and Russia have passed, and other countries are considering passing, laws that require personal data relating to their citizens to be maintained on local servers and impose additional data transfer restrictions. a Consumer Privacy Act (“CCPA”), came into effect in January 2020. The CCPA has some of the same features as the t Environi mental, Health and Safety Laws We are subject to various environmental, health and safety laws and regulations both within and outside the US, such as ory practices. Like other companies in our industry, our manufacturing and those related to safe working conditions and laborat research activities involve the purchase, storage, movement, use and disposal of substances regulated under environmental, health and safety laws, including those related to hazardous or potentially hazardous substances. a tt Other Lawsw and Regulatll ions Governingii Our Sales, ll Marketingii ii and Shipping Activitiii es We are subject to the US Foreign Corrupt Practices Act (the “FCPA”), the UK Bribery Act and various other similar anti- corruption and anti-bribery laws. Among other things, these laws generally prohibit us and our intermediaries from offering, promising or making payments to foreign government entities or officials for the purpose of obtaining or retaining business. We es. are also subject to pertinent US and foreign laws relating to the import and export of finished goods, raw materials and suppli We also must comply with various export control and trade embargo laws, which may require licenses or other authorizations for transactions within some countries or with some counterparties. Additionally, we are subject to laws and regulations governing government contracts, and failure to address these laws and regulations or complym with government contracts could harm our business by a reduction in revenue associated with these customers. We have agreements relating to the sale of our products to government entities and, as a result, we are subject to various statutet business with the government. We are also subject to investigation for compliance with the regulations governing government contracts. A failure to comply with these regulations could result in suspension of these contracts, criminal, civil and administrative penalties or debarment. s and regulations that apply to companies doing u Intellectual Property The healthcare industry has traditionally placed considerable importance on obtaining and maintaining patent, trade secret and trademark protection for commercially relevant technologies, devices, products and processes. We possess numerous patents, trade secrets and trademarks, and in the aggregate, our intellectual property is of material importance in the operation of our business. We, however, believe that no single patent, trade secret or trademark is material in relation to our business as a whole. We actively pursue patents for technologies that are considered novel and patentablea . However, important factors, many of which are not within our control, can affect whether and to what extent patent protection in the US and in other important markets worldwide is obtained. For example, the speed, accuracy and consistency in application of the law in a patent office . The resolution of issues such as these and within any particular jurisdiction are beyond our control and can be unpredictablea their effecff t on our long-term success are also indeterminable. We have issued patents, both in the US and internationally, and have patent applications pending throughout the world. 17 It has been our policy to file for patent protection in the US 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. 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 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 availablea , may not be available on acceptable terms. are successful, we may be required to ff We are aware of certain patents issued to various developers of diagnostic products with potential applicabila diagnostic technology.

In the 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 laborat ories 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. a We have registered or applied to register certain trademarks and service marks in the US and in foreign countries that are used in our business and in conjunction with the sale of our products. Our principal trademarks and the products they cover are discussed above in the section entitled “Products.” 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. Human Capital and ESG Strategies Human Capitaltt Resources As of December 31, 2021, we had approximately 1,600 employees worldwide, with approximately 1,400 employees in the union. We have experienced US and approximately 200 employees outside of the US, none of whom are represented by a labor no work stoppages and believe that our employee relations are good. a Workforce Healthll and Safety We maintain health and safety programs conforming to best practices in the diagnostics industry.

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. We strive to provide a positive work environment for all employees, consultants, contingent workers, vendors, and customers. One of the ways we accomplish this is by embracing a variety of diverse experiences and perspectives and being inclusive team players. We are dedicated to providing employees with a great place to work where they can offer their diverse talents, experiences and perspectives to innovate and create diagnostic solutions. 18 We are committed to maintaining an environment of equal employment opportunities for all job applicants and members of our team. We fulfill this commitment through a variety of measures, including internal and external posting of job openings, hiring, training and promoting employees without regard to race, color, religion, gender identity or expression, pregnancy, national origin, ancestry, citizenship, military or veteran status, t sexual orientation, age, or any other considerations made unlawful by federal, state or local law. We prohibit discrimination based on a perception that anyone has any of these characteristics or is associated with a person who has or is perceived as having any of these characteristics.

Although many of these measures have been lifted or relaxed, they could be reinstitutet and could be in place for a significant period of time, which could adversely affecff t our operations. For example, at the outset of the pandemic, we temporarily closed our corporate offices and had personnel work remotely to the extent possible and may be required to do so again in the future. affected by the inability to conduct in-person sales activities, meetings, events and conferences, which could negatively impact the success of our sales and marketing strategies and our relationships with our customers.

There are a large number of multinational and regional competitors making investments in competm ing 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 competm e with ours. A number of our competitors have competitive advantages, such as substantially greater financial, technical, research and other resources, and larger, more establia 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 affecff shed marketing, sales, ted 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 companim es attempt to strengthen or hold their market positions in an evolving industry.

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, 2021, 2020 and 2019, sales of our COVID-19 products accounted for 75%, 70% and 0% and influenza products accounted for 4%, 8%, and 26%, 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 inflff uenza tests decline for any reason, whether as a result of a waning of the COVID-19 pandemic, a mild flu season, market share loss or price pressure, 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 affecff ted on a disproportionate basis.

Four of our US distributors, collectively accounted for approximately 49%, 68%, and 51% of our total revenue for the years ended December 31, 2021, 2020 and 2019, respectively. In addition, we rely on a few key distributors for a majoa rity future. The loss or termination of our relationship of our international sales and expect to continue to do so for the foreseeablea with any of these key distributors could significantly disrupt our business unless suitablea alternatives are timely found or lost sales to a distributor are taken up by another distributor. Finding a suitable alternative to a lost or terminated distributor may pose challenges in our industry’s competm itive 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 futuret 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 affecff ted. Our resultsll of operations and financial conditiontt suppliell rs. may be adversely affected by the financial soundness of our customers and 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 reduce or terminate production of products they supply to us. Any inability of customers to pay us, or a reduction or termination of products supplied to us by suppliers, may adversely affecff t our operating results and financial condition. We may not achieve market acceptance would have a negat ivtt e effecff t on future sales. e tt of our products amongn physicians, i tt healthcare providers or other custome tt rs, and thisii A large part of our current business is based on the sale of rapid POC diagnostic tests.

If we do not capta uret 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 laborat ories 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 effecff sales at the levels anticipated in our budget, our total revenue will t on our futuret sales. a 24 Our totaltt revenue could be affected by third-party reimbursement policll ies and potentialii . cost constraints ii The end-users of our POC products are primarily physicians and other healthcare providers. In the US, 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 ted by changes for the cost of our products by their patients’ third-party payers. Our total revenue could also be adversely affecff 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.

In addition, manufacturing of certain of our product lines is concentrated in one or more of our manufacturing facilities. Weather, natural disasters, public health emergencies, fires, terrorism, political change or unrest, failure to follow specific internal protocols and procedures, equipment malfunct ion, 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. ff t If we experience unexpected increases in the demand for our products or supply shortfalls, we may be required to expend t facilities. This would increase our capita al resources to meet these demands. These capita additional capita cost of new manufacturing resources.

For examplem , in response to the demand brought on by COVID-19, we have and are continuing to rapidly and significantly expand our manufacturing capac ity, which has placed and may continue to place significant strain on our management, personnel, operations and systems.

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 unablea 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 significff ant 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 affecff 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. ted our supply allocation and could in 25 Our business is also subject to risks associated with US 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 t our operations and our ability to import materials used in our products at current or increased levels. We cannot adversely affecff predict whether additional US 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.

Futuret which could have a material adverse effecff t on our business, financial condition, results of operations or cash trade agreements could also provide our competitors with an advantage over us, or increase our costs, either of t on our business, financial condition, results of operations or cash flows. sh In addition, due to regulatory requirements relating to the qualification of suppliers, we may not be able to establia additional or replacement sources on a timely basis or without excessive cost. For example, FDA regulations and label ling requirements may make switching critical suppliers 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.

In particular, any disruptions, delays or deficiencies from our enterprise resource planning systems could adversely affecff t 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. t Our IT and storage systems are potentially vulnerablea 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 identifiablea 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. The costs of maintaining adequate protection against such threats are significant and are expected to continue to increase in the futuret and may be material to our financial statements. tt Interruptions operatingtt systemyy ii to our third-party impairm s couldll IT service providers and/or// the delivery of our cloud-base the inabilitll ytt of our digit e and negati tt d solutions altt vely impactm ll i our business. ii solutions to interoperatett withii certainii We rely on a small number of third-party service providers to host and deliver our cloud-based solutions, such as our QVue Business mobile application, and any interruptions or delays in services from these service providers could impairm delivery of our cloud-based solutions.

Our international operations are governed by the FCPA and similar anti-corruption laws outside the US. Global enforcement of anti-corruption laws has increased substant 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.

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 manufacturet our products. 27 Natural disasters, public healthtt crises, politiii cal criseii maya disrupt our facilitll iett s or the facilities of thirdii s and other catastr tt partiett s on which we depend ophic eventstt or other eventstt outside of our control ee and adversely affect our resultsll of operations. tt We have significant operations in California, near majoa r earthquake faults and exposure to wildfire, which make us susceptible to earthquake and fire risk.

Any delay in completing the Combinations could cause Topco not to realize some or all of the benefits that we expect Topco to achieve if the Combinations are successfully completed within the expected timeframe. Further, as a condition to approving the Combinations, governmental authorities may impose conditions, terms, obligations or restrictions on the conduct of our business after the completion of the Combinations. Under the terms of the BCA, the parties are not required to proffer or negotiate, or agree or consent to, any action (including any contractual, behavioral or conduct restriction, agreement, commitment or remedy) that would, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect (as defined in the BCA) on Topco. Notwithstanding the provisions of the BCA, if we were to become subject to any conditions, terms, obligations or restrictions (whether because such conditions, terms, obligations and restrictions do not rise to the specified level of materiality or because we consent to their imposition), it is possible that such conditions, terms, obligations or restrictions will delay completion of the Combinations or otherwise adversely affecff divest assets or businesses as a condition to the closing of the Combinations.

In addition, we could be subject to litigation related to any failure to complete the Combinations or related to any enforcement proceeding commenced against us to perform our obligations under the BCA.

If we receive a competing acquisition proposal and our Board determines (after consultation with our financial advisors and outside legal counsel) that such proposal constitutes a Quidel All Cash Superior u proposal to our stockholders, we would be entitled, upon complying with certain requirements, to terminate the BCA, subject to the terms of the BCA. Under such circumstances, we may be required to pay Ortho a termination fee of approximately $208 million or may be required to reimburse Ortho for its out-of-pocket expenses incurred in connection with the BCA. These provisions could discourage a third party that may have an interest in acquiring all or a significant part of us from considering or proposing such an acquisition, even if such third party was prepared to enter into a transaction that would be more favorable to us and our stockholders than the Combinations. We willii i incur signific ant transaction and merger-relat rr edtt costs in connectiontt withii the Combination ii s. We have incurred and expect to incur a number of non-recurring direct and indirect costs associated with the Combinations. These costs and expenses include fees paid to financial, legal and accounting advisors, severance and other potential employment-related costs, including payments that may be made to certain of our executives, filing fees, printing expenses and other related charges. Some of these costs are payable by us regardless of whether the Combinations are completed. There are also processes, policies, procedures, operations, technologies and systems that must be integrated in connection with the Combinations and the integration of the two companies’ businesses. While we have assumed that a certain level of expenses would be incurred in connection with the Combinations and the other transactions contemplated by the BCA and continue to assess the magnitude of these costs, there are many factors beyond our control that could affect the total amount or the timing of the integration and implementation expenses. There may also be additional unanticipated significant costs in connection with the Combinations that we may not recoup. iencies and strategic benefits we expect Topco to achieve from the These costs and expenses could reduce the realization of efficff Combinations. Although we expect that these benefits will offset the transaction expenses and implementation costs over time, this net benefit may not be achieved in the near term or at all. 29 We may have diffic associatedtt withii tt i ultytt attrac ii the Combinati ting, ii motivtt atingii ons. and retaininii gn executives and other key emplm oye ll es due to uncertaintytt Topco’s success aftff er completion of the Combinations will depend in part upon the ability of Topco to retain our key employees.

Employe may be particularly challenging during the pendency of the Combinations, as our employees may experience uncertainty about their futuret roles with Topco. e retention m In addition, pursuant to severance provisions in our executive employment agreements, certain of our key employees are entitled to receive severance payments upon certain qualifying terminations of their employment. Certain of our key employees potentially could terminate their employment following specified circumstances set forth in the applicablea employment agreement, including certain changes in such key employees’ title, status, compensation, and be entitled to receive severance. Such circumstances could occur in connection with the Combinations as a result of changes in roles and responsibilities. authority, duties, responsibilities or executive t While we may employ the use of certain retention programs, there can be no guarantee that they will prove to be successful. If our key employees depart, the integration of the companies may be more difficult and Topco’s business following the Combinations may be harmed. Furthermore, Topco may be required to incur significant costs in identifying, hiring, training and retaining replacements for departing employees and may lose significant expertise and talent relating to our business, which may adversely affecff disruptions to or distractions for the workforce and management associated with activities of labor integrating employees into Topco. Accordingly, no assurance can be given that Topco will be able to attract or retain our key employees to the same extent that we have been able to attract or retain our own employees in the past. t Topco’s ability to realize the anticipated benefits of the Combinations.

Our ability to obtain patents and licenses, and their benefits, is uncertain. • We have issued patents both in the US 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 US 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.

We may not be able to obtain licenses for we expect that we t 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 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 the 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.

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. t 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 misappropria secrets. Such claims are expensive to defend and could result in substantial damage awards and injunctions that could have a material adverse effect on our business, financial condition or results of operations.

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 $2.0 million, $2.4 million and $1.1 million for the years ended December 31, 2021, 2020 and 2019, 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.

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 HHS 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 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 effecff tive until the emergency declaration by the HHS Secretary ends and EUAs can also be revised or revoked by the FDA at any time as the FDA continues to evaluate the availablea whether there exists superior approved products.

For example, the FDA regulates most of our products, which are currently all Class I or II devices. Our futuret 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 US 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 studie complex, time-consuming and expensive process, requiring months or years to complete, and our studies are not guaranteed to generate data that demonstrate safetyt and effecff s that may be required for regulatory approvals or clearances is a tiveness or substantial equivalence of the evaluated product. t 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 affecff ted 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 marketing and use of our products. For example, prior to our acquisition of the or the placement of limits on the manufacture, 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 meter-based 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 governments’ regulatory authorities will require additional remedial or corrective actions in the future, of the FDA inspection may be expanded to cover other matters. and the issues arising out t t t Additionally, once a medical device is permitted to be legally marketed in the US pursuant to a 510(k) clearance, a manufacturer may be required to notify the FDA of certain modifications to the device (similar requirements apply in other jurisdictions). Manufacturers determine in the first instance whether a change to a product requires a new 510(k) clearance or premarket submission, but the FDA may review any manufacturer’s decision. The FDA may not agree with our decisions regarding whether new clearances are necessary. We have made modifications to our products in the past and have determined based on our review of the applicablea premarket submissions were not required. We may make similar modifications or add additional features in the futuret believe do not require a new 510(k) clearance. If the FDA disagrees with our determinations and requires us to submit 510(k) notifications, we may be required to cease marketing or to recall the modified product until we obtain clearance, and we may be subject to civil and criminal, monetary and non-monetary penalties and damage to our reputation. FDA regulations and guidance that in certain instances new 510(k) clearances or other that we new u t We are also subject to the provisions of a federal law commonly known as the anti-kickback statutet , 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 arrangements, including sales programs that may be used with hospitals, physicians, laborat of medical devices, including our products. of medical devices by limiting the kinds of financial ories and other potential purchasers a t The advertising, marketing, and label ing of medical devices is highly regulated by the FDA and 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. a We must also comply with numerous other laws applicablea 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 t on our revenues, earnings healthcare programs and civil or criminal liabilities, any of which may have a material adverse effecff 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. 33 Our contractt ts withii government entitiii es involve future funding,n complim ance ,e and possibleii i 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 NIH 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 US government generally require us to complym with the Federal Acquisition Regulations, FCA, Procurement Integrity Act, Buy American Act and Trade Agreements Act. Government contracts subject us to government audits, investigations and oversight proceedings. Government agencies routinely review and audit government contractors to determine whether they are complying with contractual 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 complim ance 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. and legal requirements.

Compliance with such laws and regulations requires significant effort manufacturing 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 substa ntial, costs, restrictions or compliance procedures on our business or operations. and costs. For examplem , our research and development and u ff Given the nature of the penalties provided for in some of these regulations, we could be required to pay sizablea 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. 34 Complying withii customersrr couldll cause us to incuii our busines s. ii various US federal, statett and foreign privacy and data securitytt lawll sw and privacyc requirementstt from our tt r substanti ali costs or require us to change our busines ii s practices in a manner adverse to Certain of our digital solutions, such as our QVue Business mobile application, collect, use, process, and store personal or t to privacy and data security laws and identifying information regarding customers or other end users, and we are subjecb regulations that impose obligations in connection with the collection, use, processing and storage of such personal or identifying information.

Furthermore, foreign privacy laws impose significant obligations on US 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.

If we are unable to maintain these certifications or meet these standards, it could reduce demand for our solutions and adversely affect our business. shed Our actual t or perceived failure to comply with these privacy and data security laws or privacy requirements may limit or delay the use and adoption of our digital solutions, reduce overall demand for our digital solutions or lead to regulatory investigations, breach of contract claims, litigation or significant fines, penalties or liabila noncompliance, any of which could negatively impact our business. ities for actual or alleged t Changes in tax law relatingtt ii to multination al corporations tt could adversely affect our taxaa position. The US Congress, government agencies in non-US jurisdictions where we and our affiliates do business, and the Organisation for Economic Co-operation and Development (“OECD”) have focused on issues related to the taxation of multinational corporations. One example is in the area of “base erosion and profit shifting,” for which the OECD has released several components of its comprehensive plan that have been adopted and expanded by many taxing authorities to address perceived tax abuse and inconsistencies between tax jurisdictions. As a result, the tax laws in the US and other countries in which we do business could change on a prospective or retroactive basis, and any such changes could adversely affecff t our business and financial statements. 35 Risks Related to Our Acquisitions IfII we are not able to manage our growth strategy technologies we may acquire,e our operatingii or if we experi tt resultsll maya be adversely affected. ence diffic xx i ultiett s identifyi i ngii tt or integr m atingn companies or Our business strategy contemplates further growth, which we expect to result in expanding the scope of operating and a al area of our operations, including further expansion outside the US, as new products and financial systems and the geographic technologies are developed and commercialized or new geographical markets are entered. Because we have a relatively small executive team, acquisitions, including the pending Combinations, and other futuret 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. growth may divert management’s attention Other risks associated with acquiring other technologies or businesses, including the pending Combinations, 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; diffiff culties transitioning and integrating the operations of companim operations, including difficulties integrating personnel, information systems, and internal control systems; es or technologies that we acquire with our own adverse effecff ts on our existing business relationships; potential loss of management and other key employees of the acquired businesses and inabila employees; ity to attract new potential litigation arising from the acquired business’s operations; potential contractual, regulatory, compliance, intellectual t 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. Transitiii oning the BNPNN Business ii to Beckman presentstt certainii ii risks to our business ii and operations. On October 6, 2017, we acquired the Triage and BNP Businesses from Alere. On July 24, 2021, we entered into agreements with Beckman to transition the BNP Business to Beckman. Pursuant to these agreements, we are obligated to supply to Beckman the antibody that Beckman uses in manufacturing its BNP tests and Beckman is obligated to pay us annual payments (payable quarterly) based on the sales volume of Beckman’s BNP tests, which payments are subject to agreed upon aggregate minimum and maximum amounts per year. These agreements also obligate us to pay to Alere the deferred consideration payable for the BNP Business even if Beckman does not make the guaranteed minimum payments to us, whether as a result of Beckman’s failure to perform under the agreements, our failure to supply the antibody needed to manufacture the BNP tests or otherwise, which presents risks to our business and operations. 36 Corporate Finance Risks funds to finance our future capital ii We may need to raiseii ll consequences on our operations and the intertt ests of our stockhol der tt additional or operatingii s.rr tt needs,s which couldll have adverse 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, including to fund the cash consideration payable in connection with the Combinations. 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 capita securities. Moreover, the availabila or the public capia tal markets, fluctuates as our financial condition and industry or market conditions in general change. There may be times when the private capita otherwise raise additional capita al markets and the public debt or equity markets lack sufficient liquidity or when we cannot al, whether debt or equity from private capita al or issue additional debt on acceptablea al through the sale of additional equity al sources (including banks) ity of additional capita 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 futuret and other general corporate requirements; financing for working capia tal, capia tal expenditures, acquisitions, debt obligations • making us more vulnerable to adverse conditions in the general economy or our industry and to fluctuations in our ting our ability to comply with and maintain any financial tests and ratios required operating results, including affecff 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 affecff t 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 futuret indebtedness will depend on the capita of these activities or engage in these activities on desirablea sufficient to service or repay our debt. Our ability to refinance our al markets and our financial condition at such time. We may not be able to engage in any terms, which could result in a default on our debt obligations. Our debt, deferre of operations. e d and contingen tt t payment obligati i ons couldll material lyll adversely affect our financ ii tt ial conditiontt and resultsll 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. In addition to our Revolving Credit Facility, we will continue to have the ability to incur additional debt. We also have 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. Additionally, as discussed under “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments” in Part II, Item 7 of this Annual Report, if the Combinations are completed, Ortho’s current net debt of $2.1 billion is expected to continue to be outstanding following the closing of the Combinations. 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 capita general corporate purposes may be impaired; al, capita al expenditures, t acquisitions and the payment of our deferredr and other strategic objectives; and contingent payment obligations reduces the funds available to us for our operations our debt agreements contain, and any agreements to refinaff 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; nce our debt likely will contain, financial and other our level of indebtedness and deferred and contingent payment obligations may increase our vulnerabila reduce our flexibility to respond to, general economic downturns and adverse industry and business conditions; ity to, and t 37 • • • • 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. Our business ii could be negat e ivtt elyll affectedtt General Risk Factors by the loss of or the inabilitll ytt 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, claimll and couldll ultimat eltt yll result in an unfavorable outcome for us. ii s and litigii ationtt that could resultll in signific i ant expenses From time to time, we are involved in litigation and other proceedings, including matters related to product liability t property claims, as well as regulatory, employment, and other claims related to our claims, commercial disputes and intellectual business. Litigation related to our company, our business, and our operations or financial performance may also involve customers, competm itors, 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 applicablea 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. laws and regulations, we could be subjected to substantial civil and criminal penalties, as well as field corrective We are exposed to business riskii 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 effecff 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 effecff t or may not be renewed at all. Further, we do not currently have insurance t on our results of operations. 38 Changes in our taxaa ratestt or exposure xx to additiii onal income taxaa liabil itll iett s or assessments could affecff ii t our profitabi .yy liii tyii ii We are subject to income taxes in the US and in various non-US jurisdictions. In addition, the amount of income taxes we pay is subject to ongoing audits by US federal, state and local tax authorities and by non-US tax authorities. Due to the potential for changes to tax laws (or changes to the interpretation thereof) and the ambiguity of tax laws, the subjecb 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 unfavorablea adjustments to our tax liabilities and our financial statements could be adversely affecff considered permanently re-invested under existing accounting standards, it could also increase our effective tax rate. In t our financial addition, any significant change to the tax system in the US or in other jurisdictions could adversely affecff statements. ted. If we determine to repatriate earnings from foreign jurisdictions that have been tivity of factual t Some provisions price of our common stocktt of our chartertt ii documents and Delaware law may make takeover attemptstt difficult, which could depress ee the and inhibit our stockholde tt rs’ abilityii 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 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 affecff 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 affecff t the rights of our stockholders. Our amended and restated bylaws include advance ting the market price of our common stock. Expectations tt of our performance related to ESG matters may impose additiii onal costs on us and expose xx us to new risks. There is an increasing focus from certain investors, customers, vendors, employees and other stakeholders concerning corporate responsibility, specifically related to ESG factors. Many investors may use these factors to guide their investment strategies and, in some cases, may choose not to invest in us if they believe our ESG performance is inadequate. Third-party providers of corporate responsibility ratings and reports have increased in number to meet growing investor demand for measurement of ESG performance. The criteria by which our corporate responsibility practices are assessed may change, which could result in greater expectations of us and cause us to undertake costly initiatives to satisfy such new criteria. If we elect not to or are unablea responsibility and ESG matters is inadequate. Moreover, our market capia talization has increased significff antly in the last couple of years. Accordingly, we may be benchmarked against larger peer companies, some of which may have more resources than us and thus may have achieved better ESG performance and/or a higher ESG rating profile. We may face reputational damage if our ESG performance or ESG rating profile is, or is perceived as being, below those of our competitors or peer companies. In addition, we could fail, or be perceived as failing, in our achievement of certain ESG-related initiatives or goals, or we could be criticized for the scope of such initiatives or goals. If we fail to satisfy the expectations of investors, customers, vendors, employees and other stakeholders related to our ESG performance or our ESG initiatives are not executed as planned, it could adversely affect to satisfy such new criteria, investors may conclude that our performance related to corporate our reputation, business, stock price, financial condition or results of operation. ff Item 1B.

Overview and Executive Summary Our primary mission is to advance diagnostics to improve human health. We have a leadership position in the development, manufacturing and marketing of rapid diagnostic testing solutions. We separate these 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 labora and wellness screening centers, as well as for individual, non-professional, OTC use. More recently, we have begun to reach significant new markets as we introduced our QuickVue At-Home OTC COVID-19 test for reopening schools, and for health departments, employers, entertainment centers and many other locations. We market our products through a network of distributors and a direct sales force. We operate in one business segment that develops, manufactures and markets our products globally. tories, urgent care clinics, leading universities, retail clinics, pharmacies tories, reference labora a a For the year ended December 31, 2021, total revenue increased 2% to $1,698.6 million as comparem d to the year ended December 31, 2020, 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 years ended December 31, 2021 and 2020, sales of our COVID-19 products accounted for 75% and 70% of total revenue, respectively. For the years ended December 31, 2021, 2020 and 2019, sales of our influenza products, as a percentage of total revenue, accounted for 4%, 8%, and 26%, respectively. Additionally, a significant portion of our total revenue is from a relatively small number of distributors. Approximately 49%, 68% and 51% of our total revenue for the years ended December 31, 2021, 2020 and 2019, respectively, were related to sales through our four largest distributors. Recent Developments On December 22, 2021, we entered into the BCA with Ortho, Topco, US Holdco Sub, US Merger Sub and US Holdco Sub 2. Under the terms of the BCA, we are entering into the Combinations with Ortho under Topco, a new holding company. The Combinations are expected to be implemented by way of (i) a scheme of arrangement to be undertaken by Ortho under Part 26 of the UK Companies Act 2006 (the “Ortho Scheme”), pursuant to which each issued and outstanding share of Ortho (the “Ortho Shares”) will be acquired by a nominee of Topco, such that Ortho will become a wholly owned subsidiary of Topco, and (ii) a merger (the “Quidel Merger”) of US Merger Sub with and into us immediately following consummation of the Ortho Scheme, with us surviving the merger as a wholly owned subsidiary of Topco. At the effective time of the Ortho Scheme, each Ortho Share will be acquired by a nominee on behalf and for the benefit of Topco in exchange for 0.1055 shares of common stock of Topco (the “Topco Shares”) and $7.14 in cash. At the effective time of the Quidel Merger, each share of our common stock (each, a “Quidel Share”) will be converted into the right to receive one Topco Share. Ortho will be acquired for total consideration of approximately $4.3 billion (which is based on the February 9, 2022 closing price of $97.64 per Quidel Share), including $1.75 billion of cash, funded through cash on our balance sheet and expected incremental borrowings. Following the closing of the Combinations, Ortho’s current net debt of $2.1 billion is expected to continue to be outstanding. If the Combinations are completed, Ortho shareholders are expected to own approximately 38% of Topco on a fully diluted basis and our stockholders are expected to own approximately 62% of Topco on a fully diluted basis, based on Ortho’s capita Combinations on Nasdaq. For additional information about the pending Combinations and the preliminary unaudited pro forma financial information, see Topco’s registration statement on Form S-4, filed with the SEC on January 31, 2022. alization as of the date of the BCA. The parties intend to list the Topco Shares to be issued in the alization and our capita 43 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 of global dissemination and effectiveness of the vaccination and containment efforts throughout the world, the duration and spread of the virus, as well as seasonality, variants or new outbrea ks. t In the US, federal, state, and local government directives and policies have been put in place to manage public health concerns and address the economic impacts, including reduced business activity and overall uncertainty presented by this new healthcare challenge. Similar actions have been taken by governments around the world. While all our facilities are currently operational globally, our facilities could be required to temporarily curtail production levels or temporari ly cease operations based on government mandates or as a result of the pandemic. To mitigate risks, we continue to evaluate the extent to which COVID-19 may impact our business and operations and adjust risk mitigation planning and business continuity activities as needed. m New SARS-CoV-2 CC Diagnost i ictt Products As a leader in POC diagnostics and with established expertise in respiratory infectious disease products, we were and remain well-positioned to respond to the COVID-19 pandemic. We work 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 developed new molecular and antigen products to diagnose the SARS-CoV-2 virus. We have experienced exceptional demand for such products. In response, we committed significant resources toward the expansion of our production capaa city. We expect demand for our molecular and antigen assays and instruments to continue for the near-term, especially in the US. At the same time, we also have observed fluctuating demand for certain of our other diagnostic products. 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 COVID-19, regulatory changes in any of the markets in which we serve, impact of new SARS-CoV-2 variants and actions to contain and treat their impacm t, including the vaccination programs that have been implemented. tt Operations and Emplm oye ll e Safetytt hiWhille ma yny ggovernments iim lplementedd llockdkdown andd hshellt ier-i ln-place dorders, ddown operatiions, our bbusiiness iis ddee customers.

Cardiometabolic Immunoassay sales increased $12.9 million over the prior year as COVID-19 restrictions began to be lifted and sales of our Triage products approac recognized for the Beckman BNP products due to the transition of this business to Beckman in August 2021. The decline in Molecular Diagnostic Solutions sales over the prior year was driven primarily by decreased pricing for the Lyra SARS Antigen assay, partially offset by higher sales of the Solana SARS Antigen assay. The decrease in Specialized Diagnostic Solutions sales over the prior year was driven by lower sales of our cell culture products, primarily dued to the lack of a respiratory season in early 2021. Currency exchange rate impact for the year ended December 31, 2021 was favorable by $7.9 million, which had a minimal impact on the growth rate. See Item 7A of this Annual Report for additional information related to our calculation and use of constant currency revenue and the constant currency fluctuat ion rate. t Gross Profit Gross profit for the year ended December 31, 2021 was $1,270.9 million, or 75% of revenue, compared to $1,348.9 million, or 81% of revenue for the year ended December 31, 2020. The decreased gross profit was driven by a shift in product mix fromff in supply chain and other indirect manufacturing costs were more than offset by increased absorption driven by higher production volumes.

We also intend to continue to year driven primarily by cash generated from operations. Additionally, during the year ended December 31, 2021, we invested a portion of our excess cash balances in a portfolio of investment-grade corporate debt securities and asset-backed securities. Our cash requirements fluctuate as a result of numerous factors, such as cash generated from operations, progress in research and development, capita evaluate candidates for new product lines, company or technology acquisitions, technology licensing or 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. On December 22, 2021, we entered into the BCA, pursuant to which we will be entering into a business combination with Ortho under Topco, a new holding company. Ortho will be acquired for total consideration of approximately $4.3 billion (which is based on the February 9, 2022 closing price of $97.64 per Quidel Share), including $1.75 billion of cash, funded through cash on our balance sheet and expected incremental borrowings. Following the closing of the Combinations, Ortho’s current net debt of $2.1 billion is expected to continue to be outstanding. Our primary source of liquidity, other than our holdings of cash and cash equivalents, has been cash flows from operations. 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 capita al resources or our ability to meet financial commitments. We anticipate that our current cash and cash equivalents, together with cash provided by operating activities and incremental borrowings will be sufficient to fund our near- term capia tal 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 al, research and development, and capia tal expenditures. Our primary short-term needs for capita al, which are subject to capita change, include expenditures related to: • • • • • acquisitions of equipment and other fixed assets in support u of our manufacturing t facility expansion; the continued advancement of research and development efforts; support of commercialization efforts related to our current and futuret sales force and field support resources; products, including support of our direct interest on and repayments of our deferred consideration, contingent consideration and lease obligations; and potential strategic acquisitions and investments. Our Convertible Notes matured on December 15, 2020. The Amended and Restated Credit Agreement (the “Credit Agreement”) provides us with a Revolving Credit Facility of $175.0 million and there was no balance outstanding as of December 31, 2021 or 2020. The Revolving Credit Facility matures on August 31, 2023. t As of December 31, 2021, we have $6.1 million in fair value of contingent consideration and $78.4 million of deferred consideration associated with acquisitions to be settled in futuret periods. On December 12, 2018, the Board authorized a stock repurchase program, allowing the Company to repurchase up to $50.0 million of its common stock. On August 28, 2020, the Board approved an amendment to the stock repurchase program that authorized repurchases of an additional $150.0 million of our common stock through August 28, 2022. For the twelve months ended December 31, 2021, 957,239 shares of outstanding common stock were repurchased under our stock repurchase program for approximately $103.4 million and as of December 31, 2021, we had approximately $52.9 million availablea under the stock repurchase program. Our future capita al requirements and the adequacy of our available funds to service any long-term debt outstanding and to fund working capia tal expenditures and business development efforts ff 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. 48 Cash Flow Summary (in thousands) Net cash provided by operating activities ....................................................................... $ Net cash used forff investing activities ..............................................................................

We exclude liabilities pertaining to uncertain tax positions from our tabla e of contractual t obligations as we cannot make a estimate of the period of cash settlement with the respective taxing authorities, nor the amount of the final cash reliablea settlement. As of December 31, 2021, we had approximately $11.6 million of liabilities associated with uncertain tax positions. See Note 4 to the Consolidated Financial Statements included in this Annual Report for further discussion of uncertain tax positions. Critical Accounting 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 US (“GAAP”). 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 fromff conditions. these estimates under different assumptions or We believe the folff lowing critical accounting policies affect our more significant judgments and estimates used in the preparation of our Consolidated Financial Statements. Reserve forff Contractual Rebates We record 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. ntory bballance as nd recorded as a Rebates are calculated based upon historical experience reduction of sales with offsets to trade accounts receivable. The allowance for contractual rebates involves estimating adjustments to revenue based upon a high volume of data including inputs fromff 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. At December 31, 2021, the reserve related to contract rebates was $40.3 million, a decrease of $60.5 million fromff third-party sources. In addition, the dand es itimated dd diist ibributor iinve the prior year. y 50 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 capia talization 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 comparem 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, 2021 and determined that no impairment existed. s the fair value of a reporting unit with the Income Taxeaa s 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 establia our deferred tax assets to the amount that is considered more likely than not to be realized through the generation of futuret taxable income and other tax planning opportunit ies. As of December 31, 2021, we had a valuation allowance of $2.3 million, which represents the portion of our 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. shed to reduce t 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 to the Consolidated Financial Statements included in this Annual Report for more information on income taxes. Item 7A.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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, 2021, 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 17, 2022 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. 54 Description of the Matter dd How We Addresse d the Matter in Our Audit tual rebatestt Reserve for contractt As described in Note 1 to the consolidated financial statements, the Company records revenues from product sales net of contractual the Company recognized an allowance on accounts receivable of $40.3 million in rebates. rebates that are estimated at the time of sale.

Company Operations and Summary of Significant Accounting Policies t Quidel Corporation (the “Company”) commenced operations in 1979. The Company operates in one business segment and markets diagnostic testing solutions. These diagnostic tests are categorized into four product that develops, manufactures categories: rapid immunoassay, cardiometabolic immunoassay, molecular diagnostic solutions and specialized diagnostic solutions. The Company currently sells its products directly to end users and distributors, in each case, for professional use in physician offices, hospitals, clinical labora tories, urgent care clinics, leading universities, retail clinics, a pharmacies and wellness screening centers, as well as for individual, non-professional, OTC use. The Company markets its products through a network of distributors and a direct sales force. tories, reference labora a The accompanying Consolidated Financial Statements of the Company and its subsidiaries have been prepared in accordance with GAAP. Consolidatdd ion—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. Cash equivalents include money market funds and debt securities of high quality institutions. Marketable Securities—The Company invests excess cash balances in investment-grade corporate debt securities, asset- t backed securities and US Treasury securities. The Company seeks to diversify investments and limits the amount of investment concentrations for individual instituti available-for-sale and, accordingly, such securities are recorded at fair value. Unrealized gains and losses that are deemed temporary are included in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. If any adjustmd the decline is determined to be other-than-temporary and would mark the security to market through a charge to its Consolidated Statements of Income. Marketable securities are classified as non-current when maturities are one year or more. ent to fair value reflects a significant decline in the value of the security, the Company evaluates the extent to which ies and investment types. These marketable securities are classified as ons, maturit t Accountstt Receivable—The Company sells its products directly to hospitals, reference laborat a ories, retail clinics, pharmacies, as well as to distributors in the US 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 is net of reserves of $52.4 million and $103.4 million at December 31, 2021 been material. The balance of accounts receivablea and 2020, respectively, of which the reserve related to contract rebates was $40.3 million and $100.8 million, respectively. Concentration of Credit Risk—ii credit risk consist principally of cash equivalents, marketablea Financial instruments that potentially subject the Company to significant concentrations of . securities and trade accounts receivablea Credit losses are identified when cash flows received are not expected to be sufficient to recover the amortized cost basis of a security. In the event of a credit loss, only the amount associated with the credit loss is recognized in operating results, with the amount of loss relating to other factors recorded in accumulated other comprehensive income (loss). 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 receivablea 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. s is moderated by its credit evaluation Inventories—Inventories are stated at the lower of cost (first-in, first-out) or net realizablea 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,yy Plant l and Equipment—tt Property, plant and equipment are 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. 62 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 establia technological feasibility is establia the estimated product life. shed, software development costs are capia talized and amortized on a straight-line basis over shed. After Convertible Debt—tt 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 the Company’s 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. Determining the fair value of the debt component requires the use of accounting estimates and assumptions. These estimates and assumptions are judgmental in naturet component, and the associated non-cash interest expense. See Note 3 for additional discussion of the Convertible Notes issued in December 2014. and could have a significant impact on the determination of the debt 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 and other current liabilities, respectively. balances and recorded as a reduction of sales with offsets to accounts receivablea Transaction price for a contract represents the amount to which we are entitled in exchange for providing goods and services to the customer. Transaction price does not include amounts subject to uncertainties unless it is probable that there will be no significant reversal of revenue when the uncertainty is resolved. 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.

As of lrelat ded to right right of returnt historicall inties i i t i 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 capita alized 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 consumablea consumablea 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 Consideration from the contract is allocated to each deliverablea 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 that relates to capita as a reduction to the carrying value of such assets and amortized over the useful life of the assets.

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 issuablea options, unvested RSUs and the Convertible Notes. Potentially dilutive common shares from outstanding stock options and unvested RSUs are determined using the average share price forff each period under the treasury stock method. from stock Potentially dilutive common shares from the Convertible Notes are determined using the if-converted method. Under the provisions of the if-converted method, the Convertible 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 Notes is added back to net income. The Convertible 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 Notes became convertible on March 31, 2018 and maturet d on December 15, 2020.

The partnership continues to be a VIE for which the Company is now the primary beneficiary. The Company accounted for the GP interest as an asset acquisition and recorded building and land with a total value of $28.9 million. Prior to the purchase date, the Company was leasing the McKellar Property through 2030, with options to extend for two additional five‑year periods.

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 forff trading or other speculative purposes. ff Such foreign currency forward 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.
