Enterprise Strategy

The Company provides vital information to help its customers make clear and confident health decisions. Through its science, data, and global laboratory network, the Company accelerates and advances innovations in testing and treatments to improve patient care.

The Company is expanding its role in the rapidly evolving healthcare market by strengthening its positions across its portfolio of capabilities, growing strategic opportunities that drive new business, and differentiating its unique offerings, capabilities, and financial performance. To do so, the Company is focusing on executing the following strategic priorities, which have evolved to reflect its operations and strategic vision:

1.Build on the Company's Leadership in Oncology

The field of oncology receives significant investment in research, development, and treatment, yet it remains an area of great unmet medical need. The Company believes the diagnosis and treatment of cancer will be the fastest-growing therapeutic area in the near future.

Index

With the increased adoption of precision medicine, health and cancer care providers are relying on advanced testing to identify patients who will benefit from new, targeted treatments and therapies that are more effective and often have fewer side effects than chemotherapy and other traditional treatments. Since forming an oncology business unit and launching an enterprise oncology platform in 2021, the Company has become an oncology leader. By focusing its diagnostic and drug development services on the fight against cancer, the Company is delivering targeted solutions that power better decision and improved patient outcomes. The Company believes it maintains the broadest portfolio and capabilities in oncology diagnostics today. The Company intends to accelerate its leadership and enhance its offerings, particularly in genomic testing, personalized medicine and liquid biopsy. The Company is also leveraging its oncological capabilities and platforms to progress its work in other areas, including neurodegenerative disease, autoimmune and liver diseases, and cell and gene therapy.

In 2022, the Company completed its acquisition of Personal Genome Diagnostics (PGDx), a provider of comprehensive liquid biopsy and tissue-based genomic products and services. The acquisition of PGDx enhances the Company's precision diagnostic portfolio and its ability to increase access to oncology care globally. In addition, the Company continues to realize benefits from its portfolio of OmniSeq products such as OmniSeq INSIGHT, a comprehensive genomic and immune profiling, tissue-based test that integrates next-generation sequencing (NGS) technology.

2. Differentiate Through Digital and Data

The healthcare and life sciences industries remain among the most significantly impacted by technological advancements. By maximizing the use of advances in artificial intelligence (AI), data, digitalization, and analytics in compliance with applicable regulations, the Company strives to improve operating efficiency and business performance, and to create new, differentiated products and services that the Company believes will help its customers and deliver better care to patients.

The Company is using AI to better identify and predict trends such as the timing and location of demand shifts for certain tests. In doing so, the Company is supporting an efficient use of supplies, staffing, and the Company’s advanced logistics used to route testing to the most appropriate laboratories and quickly deliver results. AI capabilities and advanced logistics have played, and are expected to continuing playing, an important role in the Company’s response to periods of heightened demand for COVID-19 polymerase chain reaction (PCR) testing.

The Company creates, and has access to, significant volumes of data. By applying advanced analytics to its data in compliance with data privacy regulations, the Company can help its customers improve their processes and reach better outcomes. The Company’s repository of test results help study sponsors assess patients' eligibility for clinical trials more quickly and accurately, enroll those patients faster, shorten the time needed for regulatory submission, and accelerate the availability of new medicines. Data is also being used by the Company to advance science and the public's understanding of certain treatments and illnesses.

Digitalization continues to be an area of focus for the Company as it responds to the use of technology-enabled tools and services by healthcare providers, patients and pharmaceutical companies for absorbing, handling, and disseminating information. These services include decentralized clinical trials, which offer the potential to remove barriers that may have slowed or prevented studies from being conducted in the past. Decentralized clinical trials can also make trial participation an option for more people, including individuals from underrepresented populations.

In the U.S., the Company continues to improve its patients' experience in patient service centers (PSCs) by creating a seamless digital journey from appointment scheduling to results delivery. With an average of 3 million patients served in a given week, the Company strives to enhance their experience using its digital channels.

3. Drive Customer Centricity

The Company serves a broad range of customers, including managed care organizations (MCOs), pharmaceutical, biotechnology, medical device and diagnostics companies, governmental agencies, physicians and other healthcare providers, hospitals and health systems, employers, patients and consumers, CROs, and independent clinical laboratories. The Company continues to focus on its customers, anticipate their needs, and deliver valuable solutions that help them achieve their goals.

The Company prioritizes a consistent, coordinated focus across all aspects of its operations, placing the customer at the center of its services, with the objective of becoming the customer's primary partner for solutions to their needs. In an effort to provide a leading customer experience, the Company seeks customer feedback, communicates best practices and lessons learned, and provides robust employee training with respect to the needs of its customers.

The Company routinely introduces new products, services, and initiatives that benefit its customers. For example, the Company launched a new test in mid-2022 to assist in the identification and confirmation of neurodegenerative disease and neuronal injury. The Company also expanded access to its services in the Midwestern U.S. with the opening of a new laboratory, and it announced plans to expand its laboratory footprint in Japan. In addition, the Company continues to experience

Index

growing demand for its consumer-initiated wellness testing available through Labcorp OnDemand, and it believes its pipeline of innovative, consumer-focused offerings is strong.

4. Expand Globally

The Company has a long history of disciplined use of capital to invest in the growth of the business and intends to grow its business globally by leveraging its advanced laboratory network, scientific capabilities, health data and insights, and its results-oriented culture to achieve better health for all people.

The Company has made significant investments in the deployment of new technologies through both licensing and internal research and development, as well as strategic and tuck-in acquisitions. The Company has also invested in establishing collaborative partnerships with other leading companies and organizations that share the Company’s goals and expectations.

The Company continually evaluates its business and the broader healthcare and life sciences markets to proactively identify and assess:

•potential growth opportunities;

•business areas that might not support continued growth and should be revamped or divested;

•acquisition targets that meet its criteria for quality, value, and return on investment;

•new products that would successfully integrate with or extend the Company’s offerings; and

•a balanced formula for capital allocation.

Through a continued focus on these strategic priorities, reinforced through the Company's capital allocation plan, the Company expects to be in an optimal position to make disciplined choices that maximize shareholder value, better protect the Company from market fluctuations and outside impacts, and fuel significant and profitable short- and long-term revenue growth.

COVID-19 Pandemic Response

The Company has supported the fight against COVID-19 since the earliest stages of the pandemic, and it continues to play an important role in ongoing response efforts.

In 2022, the Company further expanded access to COVID-19 testing and continued to support the development of COVID-19 vaccines and therapies.

The Company received FDA Emergency Use Authorization (EUA) for multiple innovations during the year. In June, the Company was granted FDA EUA for its next-generation sequencing test used to identify specific SARS-CoV-2 lineages. This was the first test authorized for the identification and differentiation of SARS-CoV-2 Phylogenetic Assignment of Named Global Outbreak (PANGO) lineages, which are genetic variations in circulating virus strains. The Company also received FDA EUA for the first non-prescription, at-home collection kit for combined COVID-19, flu and respiratory syncytial virus (RSV) detection. These achievements built on the Company's first COVID-19-related FDA EUA, which was received on March 16, 2020, for COVID-19 PCR testing, the FDA EUA in April 2020 for the Pixel by Labcorp COVID-19 test home collection kit, and in December 2020 for over-the-counter purchase of these home collection kits.

The Company's additional contributions to the pandemic response in 2022 included assisting in the identification and monitoring of COVID-19 variants and spikes in confirmed cases, as well as expanding no-cost access to at-home test collections for individuals who met clinical guidelines. The Company maintained its ability to quickly scale up COVID-19 PCR testing capacity throughout the year, even during periods of reduced demand. In doing so, the Company was able to immediately and effectively respond to surges in positive cases and testing needs. The Company performed approximately 13 million COVID-19 PCR tests and 1 million antibody tests in 2022, and since the start of the pandemic has performed approximately 74 million COVID-19 PCR tests and 9 million antibody tests.

COVID-19 Outlook

COVID-19 has had, and continues to have, a substantial impact on the global health and economic environments. The Company continues to closely monitor the impact of the COVID-19 pandemic on all aspects of its business, given continued unpredictability, corresponding state, local and federal government restrictions and policies, the continued emergence of new variants that may cause increases in cases that may impact the Company, and the potential for shifts in customer behavior.

While the Company anticipates that COVID-19 will continue impacting its business in 2023 and potentially beyond, the Company expects a continued decline in demand for COVID-19 Testing, with the potential for increases in demand at different times and across different geographies. As a result, COVID-19 Testing demand in 2023 is not predicted to match 2022 levels.

Capital Allocation

The Company believes it has a strong track record of deploying capital to investments that enhance the Company's business and return capital to shareholders.

During 2022, the Company invested $1,164.0 million in strategic business acquisitions. The acquisitions have expanded the Company’s service offerings, expanded its customer and revenue mix, and strengthened and broadened the scope of its geographic presence. The Company continues to evaluate acquisition opportunities that leverage the Company’s core competencies, complement existing scientific and technological capabilities, increase the Company’s presence in key geographic, therapeutic and strategic areas, and meet or exceed the Company’s financial criteria.

During 2022, the Company repurchased 5.6 million shares of its common stock at an average price of $233.48 for a total cost of $1,100.0 million. This included 0.9 million shares which were repurchased in 2022 but were part of the $1,000.0 million Accelerated Share Repurchase (ASR) Program paid for in 2021. At the end of 2022, the Company had outstanding authorization from the Board to purchase $531.5 of Company common stock. On February 7, 2023, the board of directors adopted a new share repurchase plan authorizing up to $1,000.0 of the Company's shares in addition to the remaining amount outstanding under the previous plan. The repurchase authorization has no expiration. The repurchase authorization has no expiration date.

During 2022, capital expenditures were $481.9 million. The Company expects capital expenditures in 2023 to be approximately 3.5% of revenues, primarily in connection with projects to support growth in the Company's core businesses, facility expansion and updates, projects related to its LaunchPad initiative, and further acquisition integration initiatives.

The Company will continue to evaluate opportunities for strategic deployment of capital in light of market conditions.

Seasonality and External Factors

The Company experiences seasonality across its business. For example, testing volume generally declines during the year-end holiday period and other major holidays and can also decline due to inclement weather or natural disasters. Declines in testing volume reduce revenues, operating margins and cash flows. Operations are also impacted by changes in the global economy, exchange rate fluctuations, political and regulatory changes, the progress of ongoing studies and the startup of new studies, as well as the level of expenditures made by the pharmaceutical, biotechnology and medical device industries in R&D. As discussed in more detail elsewhere in Item 1, COVID-19 impacted the Company in 2022. This impact included the effect of the Company’s response to the virus through its testing and drug development services, as well as the effect of COVID-19 on the global economy and demand for the Company’s non-COVID-19 services.

In 2022, approximately 14.7% of the Company's revenues were billed in currencies other than the U.S. dollar, with the Swiss franc, British pound, Canadian dollar, and the euro representing the largest components of its currency exposure.

Given the seasonality and changing economic factors impacting the business, comparison of the results for successive quarters may not accurately reflect trends or results for the full year.

The Company reports its business in two segments, Dx and DD. In 2022, Dx and DD contributed 61% and 39%, respectively, of revenues to the Company, and in 2021 contributed 64% and 36%, respectively. Nearly all of Dx’s revenues are generated in the U.S., with a smaller portion in Canada and a relatively small amount in the rest of the world. DD’s revenues are nearly evenly split between the U.S. and the rest of the world, with approximately 48% derived from the U.S. and approximately 52% from other countries. Although this allocation of revenues provides some protection from economic shifts in any one country, it is still heavily tilted towards the U.S. As a result, the Company continues to actively explore new and expanded business opportunities outside the U.S. to further diversify its sources of revenues. The Company's revenues by segment payers/customer groups and by geography for the years ended December 31, 2022, 2021 and 2020 are as follows:

During the fourth quarter of 2022, the Company modified the segment performance measure to exclude the amortization of intangibles and other assets, restructuring and other charges, goodwill and other asset impairments, and certain corporate charges for items such as transaction costs, COVID-19 costs, and other special items. These changes align with how the CODM now evaluates segment performance and allocates resources. Prior periods have been conformed for comparability.

Dx Segment

During 2022, the Dx segment generated $9,203.5 million in total revenues and $2,025.5 million in segment operating income, resulting in an operating margin of 22.0%.

results, nimble and efficient logistics, and local labs offering rapid response testing.

Dx also provides patient access points that are strategically and conveniently located throughout the U.S., including more than 2,000 PSCs and more than 6,000 in-office phlebotomists located in customer offices and facilities. Although testing for healthcare purposes and customers who provide healthcare services represents the most significant portion of the clinical laboratory industry, clinical laboratories also perform testing for other purposes and customers, including employment and occupational testing, DNA testing to determine parentage and to assist in immigration eligibility determinations, environmental testing, wellness testing, toxicology testing, pain management testing, and medical drug monitoring. Dx offers an expansive test menu that includes a wide range of clinical, anatomic pathology, genetic and genomic tests, and regularly adds new tests and improves the methodology of existing tests to enhance patient care. Dx also offers consumer-initiated wellness testing available online through its Labcorp OnDemand™ platform. The Pixel by Labcorp COVID-19 PCR and combined COVID-19 + flu at-home collection kits are also available through Labcorp OnDemand. Dx typically processes tests for more than 3 million patient encounters each week.

As part of an ongoing commitment to be an efficient and high-value provider of laboratory services, Dx implemented a comprehensive business process improvement initiative known as LaunchPad. The initiative was designed to reengineer the Company's systems and processes to create a sustainable and more efficient business model, and to improve the experience of all stakeholders. Dx’s LaunchPad initiative delivered approximately $200 million in net savings for the period of late 2018 through the end of 2021.

Effect of U.S. Market Changes on the Clinical Laboratory Business

The delivery of, and reimbursement for, healthcare continues to change in the U.S., impacting all stakeholders, including the clinical laboratory business. Medicare (which principally serves patients who are 65 and older), Medicaid (which principally serves low-income patients) and insurers have increased their efforts to control the cost, utilization and delivery of healthcare services. Measures to regulate healthcare delivery in general and clinical laboratories in particular have resulted in reduced prices, added costs, increased coverage denials and claims edits, and decreased test utilization for the clinical laboratory industry by imposing new, increasingly complex regulatory and administrative requirements. The government also has continued to adjust the Medicare and Medicaid fee schedules at the national and local level, and the Company believes that pressure to reduce government reimbursement will continue.

Fees for most laboratory services reimbursed by Medicare are established in the Clinical Laboratory Fee Schedule (CLFS) and fees for other testing reimbursed by Medicare, primarily related to pathology, are covered by the Physician Fee Schedule (PFS). During 2022, approximately 8.9% of Dx’s revenue was reimbursed under the CLFS (8.5% in 2021), and approximately 0.4% was reimbursed under the PFS (0.4% in 2021). Dx has experienced governmental reimbursement reductions as a direct result of several Congressional acts and regulatory initiatives. These laws include provisions designed to control healthcare expenses reimbursed by government programs through a combination of reductions to fee schedules, incentives to physicians to participate in alternative payment models such as risk-sharing, and new methods to establish and adjust fees.

The most significant of these developments was the Protecting Access to Medicare Act (PAMA), which became law on April 1, 2014, and which went into effect on January 1, 2018. Beginning in 2018, under PAMA, the Centers for Medicare and Medicaid Services (CMS) of the U.S. Department of Health and Human Services (HHS) set the CLFS using the weighted median of reported private payer prices paid to certain laboratories that receive a majority of their Medicare revenue from the CLFS and PFS and that bill Medicare under their own National Provider Identifier (NPI). Applicable labs, including Dx, were required to begin reporting their test-specific private payer payment amounts to CMS during the first quarter of 2017. CMS used that private market data to calculate weighted median prices for each test (based on applicable current procedural technology (CPT) codes) to represent the new CLFS rates beginning in 2018, subject to certain phase-in limits. For 2018 through 2020, a test price could not be reduced by more than 10.0% per year. PAMA resulted in a net reduction in reimbursement revenue of approximately $245.0 million between 2018-2020 from all payers affected by the CLFS.

Due to enactment of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) passed by Congress on March 27, 2020, the Medicare reimbursement cuts that would have occurred under PAMA in 2021 were delayed by one year. In 2021, Dx realized an increase of approximately $0.3 million in PFS revenue as a result of the provisions included in the Omnibus Appropriations and Coronavirus Relief Package. In 2021, Dx realized an additional increase of approximately $5.8 million in aggregate Medicare reimbursement associated with the suspension of sequestration through December of 2021, as a result of provisions included in the Omnibus Appropriations and Coronavirus Relief Package that were extended as a result of an Act to Prevent Across-the-Board Direct Spending Cuts.

On December 10, 2021, President Biden signed into law the Protecting Medicare and American Farmers from Sequester Cuts Act, which delayed by one additional year the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2022, resulting in a 0% update to the CLFS in 2022. In 2022, Dx realized a decrease of approximately $0.4 million in PFS revenue driven by reductions in reimbursement for flow cytometry procedures and a decrease of approximately $10.0 million in aggregate Medicare reimbursement associated with the phased in reinstitution of sequestration as a result of provisions included in the Protecting Medicare and American Farmers from Sequester Cuts Act.

The Protecting Medicare and American Farmers from Sequester Cuts Act also included mitigations to several other non-PAMA Medicare cuts in addition to delaying Medicare reimbursement cuts under PAMA. It delayed the 4% Medicare cuts that would otherwise have occurred in 2022 under statutory “pay-as-you-go,” or PAYGO, rules to offset the cost of the American Rescue Plan Act by one year. In addition, it delayed the resumption of the 2% Medicare sequestration until April 1, 2022, and reduced to 0.75% the previous 3.75% reduction to PFS reimbursement that was scheduled for 2022. To offset the cost, the Medicare sequestration was increased to 2.25% for January through June of 2030, and to 3.0% for July through December 2030.

On December 29, 2022, President Biden signed into law H.R. 2617, the Consolidated Appropriations Act, 2023, which delayed by one additional year the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2023, resulting in a 0% update to the CLFS for 2023. The Consolidated Appropriations Act, 2023 also included mitigations to several other non-PAMA Medicare cuts in addition to delaying Medicare reimbursement cuts under PAMA. It delayed until October 1, 2024 the 4% Medicare cuts that would otherwise have been effective January 1, 2023 under PAYGO rules. In addition, it mitigated PFS cuts in 2023 and 2024 to by 2.5% and 1.25%, respectively, that would otherwise have been (4.47%) in 2023 based on the conversation factor put forward in the 2023 Medicare PFS Final Rule. To offset the

Index

cost, it extended the 2% Medicare sequestration through the first six months of 2032 and set the sequestration percentage at 2% in fiscal years 2030 and 2031.

In 2023, Dx anticipates a net PFS revenue increase of 0.8% ($0.3 million) from the 2023 PFS Final Rule, driven by a (2.0%) change to the PFS conversion factor that is offset by net positive changes in relative value units (RVUs) for flow cytometry and changes to RVUs for other PFS procedures. The 2023 PFS Final Rule also included an increase in the CLFS fee for specimen collection by venipuncture from $3.00 to $8.57, which is estimated to increase Dx CLFS revenue for specimen collection by $38.6 million in 2023.

Pursuant to PAMA as amended, for 2024 through 2026, a CLFS test price cannot be reduced by more than 15.0% per year (excluding non-PAMA reimbursement changes). CLFS rates for 2027 and subsequent periods will not be subject to phase-in limits. The phase-in of rates for Clinical Diagnostic Laboratory Tests (CDLTs) established in 2018 will resume in 2024. New CLFS rates will be established in 2025 based on data from 2019 to be reported in 2024. New CLFS rates will be established in 2028 based on data from 2026 to be reported in 2027. CLFS rates for Advanced Diagnostic Laboratory Tests will be updated annually.

The American Clinical Laboratory Association (ACLA) filed a federal civil action in 2017 challenging the legal basis for the data collection methodology CMS used to derive the data from which the median prices were calculated. On July 15, 2022, the U.S. Court of Appeals for the D.C. Circuit ruled in favor of ACLA on the merits, finding that CMS harmed laboratories by collecting data in an arbitrary and capricious manner, but refused to grant relief due to PAMA’s statutory bar on judicial review of establishment of the rates.

Since the initial data collection, CMS has revised its PAMA regulations to increase the number of hospital outreach labs that will be required to report private market data in future collections. Reports by the U.S. Government Accountability Office (GAO), the HHS Office of Inspector General (OIG), and the Medicare Payment Advisory Commission (MedPAC) on PAMA implementation have identified certain instances of actual or potential increased Medicare expenditures under PAMA, as well as potential alternative methodologies for data collection under PAMA, which could result in further efforts to amend PAMA by Congress.

ACLA has continued to work with Congress on potential legislative reform of PAMA, which if adopted could reduce the negative impact of PAMA as currently implemented by CMS. Under the Laboratory Access for Beneficiaries (LAB) Act, MedPAC was required to conduct a study and make recommendations to Congress on ways to improve data collection, reporting, and rate setting under PAMA to achieve, in a less burdensome manner, CLFS rates that accurately and fairly reflect private market rates. MedPAC's June 2021 report to Congress included an analysis of potential statistical sampling methodologies that could accomplish that objective, and ACLA incorporated the concept in PAMA reform proposals to Congress. On June 22, 2022, the Saving Access to Laboratory Services Act (S. 4449 H.R. 8188) was introduced in both the U.S. Senate and the U.S. House of Representatives to provide for permanent reform of PAMA incorporating many of ACLA’s proposals. The Company supports the ongoing efforts to prevent or lessen the negative impact of the changes to the CLFS pursuant to PAMA, and the full impact of those efforts, but what the long-term effect will be on the CLFS rates is not yet known.

Further healthcare reform could occur in 2023, including changes to the Patient Protection and Affordable Care Act (ACA) and Medicare reform, as well as administrative requirements that may continue to affect coverage, reimbursement, and utilization of laboratory services in ways that are currently unpredictable.

In addition, market-based changes have affected and will continue to affect the clinical laboratory business. Reimbursement from commercial payers for diagnostic testing may shift away from traditional, fee-for-service models to alternatives, including value-based, bundled pay-for-performance, and other risk-sharing payment models. The growth of the managed care sector and consolidation of MCOs present various challenges and opportunities to Dx and other clinical laboratories. Dx's ability to attract and retain MCO customers has become even more important as the impact of various healthcare reform initiatives continues, including expanded health insurance exchanges and ACOs.

The Company serves many MCOs. These organizations have different contracting philosophies, which are influenced by the design of their products. Some MCOs contract with a limited number of clinical laboratories and engage in direct negotiation of rates. Other MCOs adopt broader networks with generally uniform fee structures for participating clinical laboratories. In some cases, those fee structures are specific to independent clinical laboratories, while the fees paid to hospital-based and physician-office laboratories may be different, and are typically higher. MCOs may also offer Managed Medicare or Managed Medicaid plans. In addition, some MCOs use capitation rates to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement arrangement, the clinical laboratory receives a per-member, per-month payment for an agreed upon menu of laboratory tests, or based upon the proportionate share earned by the clinical laboratory from a capitation pool. When the agreed upon reimbursement is based solely on an established rate per member, revenue is not impacted by the volume of

Index

testing performed. Under a capitation pool arrangement, the aggregate value of an established rate per member is distributed based on the volume and complexity of the procedures performed by laboratories participating in the agreement. For the year ended December 31, 2022, capitated contracts with MCOs accounted for approximately $332.3 million, or 3.2%, of Dx's revenues.

In addition to reductions in test reimbursement, the Company also anticipates potential declines in test volumes as a result of increased controls over the utilization of laboratory services by Medicare, Medicaid, and other third-party payers, particularly MCOs. MCOs are implementing, directly or through third parties, various types of laboratory benefit management programs, which may include laboratory networks, utilization management tools (such as prior authorization and/or prior notification), and claims edits, which impact coverage and reimbursement of clinical laboratory tests. Some of these programs address clinical laboratory testing broadly, while others are focused on certain types of testing, including molecular, genetic and toxicology testing. In addition, continued movement by patients into consumer-driven health plans may have an impact on the utilization of laboratory testing. Test volumes in 2023 could also change compared to 2022 and 2021 if demand for SARS-CoV-2 testing changes.

Helping to balance the overall negative market changes regarding reimbursement discussed above, the Company believes that the volume of clinical laboratory testing is positively influenced by several factors, including an increase in the number and types of tests that are readily available (due to advances in technology and increased cost efficiencies) for the diagnosis of disease, and the general aging of the U.S. population. Periodic infectious disease outbreaks such as the SARS-CoV-2 virus also have the potential to generate additional testing volume in the future, and enhance stakeholders’ appreciation for the value of laboratory testing in combating future potential outbreaks. Dx believes that its enhanced and growing esoteric menu of tests, leading position with companion diagnostics, broad geographic footprint, and operating efficiency make it well positioned for growth due to a number of market factors, primarily related to a continued drive to improve outcomes and reduce costs across the healthcare system, including but not limited to greater price transparency required under “surprise billing” laws and regulations requiring disclosure of hospital charges.

Engaging the collective expertise and passion of its employees is vital to achieving the Company’s mission, which permeates its performance-driven, collaborative, inclusive, customer-centered, and inquisitive culture.

Workforce Demographics

The Company’s success depends on its sustained ability to attract, develop, and retain a highly specialized and skilled global workforce. Employees are globally dispersed, with 77% in the U.S. and Canada, 11% in Asia, 11% in Europe, the Middle East, and Africa, and 1% in Latin America. Of the Company’s global workforce, 88% of employees are full time, and 12% are part time. 3.3% of Labcorp’s global workforce is employed under a collective bargaining agreement. Depending on business demand and the talent-hiring environment, Labcorp supplements up to 8% of its workforce with contingent workers.

The challenges of 2022, felt globally, also presented the Company with significant challenges in acquiring and retaining talent. Despite these obstacles, Labcorp’s global workforce increased by more than 10% from a combination of organic growth and adding employees through acquisitions. The majority of Labcorp's hires are sourced through an internal talent acquisition

team. The Company made significant investments to retain talent and enable the organization to meet the business needs for growth, which are discussed further in the section below on “Compensation and Benefits.”

Throughout the COVID-19 pandemic, the majority of employees who do not work with patients, animals, in labs, or in logistics, worked remotely. This includes call center employees, customer service teams, sales teams, and corporate and functional teams. While some employees returned to on-site work in 2022, the Company expects that a significant number of employees will continue working remotely, or through hybrid, in-office and remote work arrangements. The Company believes that flexibility in work location and arrangements expands the pool from which it can source experienced and valuable talent.

Diversity and Inclusion

Labcorp's diverse, global talent is core to its ability to innovate and meet patient and customer needs. The Company believes that the diversity of its employees and its inclusive programs contribute to a healthy, productive, and respectful work environment.

The Company now has eight unique ERGs with 106 chapters in 15 countries, growing by more than 30 local chapters from 2021. Each ERG has executive sponsorship from senior leadership; and

•celebration of different cultures, constituencies, and observances throughout the year, including a “Days of Understanding” series in partnership with ERGs and in alignment with CEO Action, a business-led initiative to advance diversity, equity and inclusion in the workplace.

The Company was named to FORTUNE magazine's 2022 List of World's Most Admired Companies, making the annual list for the fourth time. Labcorp also made the Forbes 2022 list of World's Best Employers for the third consecutive year, as well as the Forbes 2022 List of Best Employers for New Graduates. In 2022, the Company was recognized for the fifth consecutive year as a Best Place to Work for LGBTQ+ Equality, with a score of 100% on the Human Rights Campaign Foundation's Corporate Equality Index. The Index is the nation's foremost benchmarking survey and report on corporate policies and practices related to LGBTQ+ workplace equality.

The Company was also named as a Best Place to Work for Disability Inclusion by the Disability Equality Index and one of Newsweek's 2022 America's Most Responsible Companies.

The Company has also implemented opportunities for greater engagement between employees and management. These include quarterly global town halls that are held virtually and are open to all employees, interactions with front-line employees on visits to the Company's facilities, and in-person town halls with employees in select business units. In early 2022, the Company initiated a Voice of the Employee Survey. Responses were received from nearly 50% of Company employees across 64 countries. The insights provided by employees are being used to make improvements in the virtual onboarding experience for new employees, introduction of a modern global human resources portal, and a reimagined U.S. benefits portal to help employees to better evaluate their benefits options.

Compensation

The Company operates in a complex, global, and dynamic life sciences industry and believes that its compensation and benefits programs must continue to be competitive and flexible to attract and retain the caliber of talent needed to sustainably grow the business. In 2022, the Company’s workforce grew by over 10%. The Company believes that its ability to expand the workforce in 2022 provides support that the Company's compensation and benefit strategies are competitive and support the Company's ability to attract and retain talent.

The Company continually monitors market activity and employee movement within and outside of the core life sciences industry to maintain competitiveness, given the dynamic business and economic environment and labor market challenges it faces. In 2022, the Company invested more than $39 million in pay adjustments in addition to annual pay increases, to increase pay competitiveness in the markets in which we compete for talent.

Employee Wellness

The Company also continued investing in the health and wellness of its global workforce, with particular emphasis on improving its U.S. health benefits program for employees. The Company’s efforts on this front included:

•no annual cost increase for the payroll contributions in its U.S. Healthy medical, dental and vision insurance plans, impacting approximately 35,000 covered employees and more than 30,000 dependents. For approximately 19,000 employees in the U.S. earning less than $50,000 per year, the Company further reduced the cost of monthly medical insurance contributions by $240 per year;

•providing up to $4,560 in annual medical plan contribution discounts for over 35,000 employees and their spouses and domestic partners for committing to and maintaining a healthy and tobacco-free lifestyle;

•encouraging health and wellness education and activities by providing up to $1,000 in Health Reimbursement Account contributions to approximately 35,000 employees and their spouses or partners; and

•reimbursing up to $300 in fitness-related costs for approximately 13,000 employees.

The Company routinely continually educates its workforce on health issues of importance and has prioritized continuous education on the importance of mental well-being by providing communications and resources to all employees. The Company

Index

believes that its investments in compensation and wellness are crucial to maintaining competitive positioning and a productive and engaged workforce.

Development and Training

To meet the needs of patients and clients in the evolving and competitive diagnostics and drug development markets, the Company is committed to creating a work environment that supports a focus on the continuous development and training of its employees. With this focus, the Company believes it is well-positioned in the long term to meet the demands of the regulatory environment and accelerate its ability to innovate and develop talent in a highly skilled and competitive talent market.

Labcorp's curriculum has three primary focus areas: regulatory training; technical training; and professional development. Regulatory training is required by laws and regulations for the Company to operate in certain areas within the life sciences industry and in certain jurisdictions. Technical training and professional development enable the Company to compete more effectively in the life sciences industry.

The Company maintains an extensive library of over 48,000 courses that are available virtually within its global learning management system. In 2022, Labcorp employees completed over 2.7 million hours of training, primarily consisting of regulatory and technical training. In addition, due to the Company’s access to sensitive and personally identifiable information, employees completed over 720,000 IT security training courses, representing more than 150,000 total hours, with the goal of maintaining IT system safety and security for clients and patients.

Labcorp also invests in the professional development of its talent, and in retaining its best employees for future internal opportunities. In 2022, employees completed more than 50,000 hours of professional development. In addition, 343 employees completed the Labcorp UK Apprenticeship program that the Company plans to expand in 2023 to include US employees.

Challenges in the talent labor market have reinforced the need to offer new and engaging learning resources. In 2021, the Company expanded its approach to tuition assistance. Through 2022, the Labcorp Education Advantage program has fully sponsored 742 employees in their pursuit of higher education in the sciences, with 13 employees completing their bachelor’s degree with this benefit. Employees enrolled in the Labcorp Education Advantage program have an 11 point lower attrition rate than the global population, evidencing a strong social and human capital impact. In addition, Labcorp added new relationships with leading academic institutions and learning partners that provide open, online courses. These partners provide video courses, job aides, and short, self-paced learning taught by industry experts.

Health and Safety

The nature of the Company's business requires employees to work directly with patients and animals. This includes the handling, processing, and testing of human or animal specimens on a daily basis. As the health and safety of employees is a primary concern, the Company has established numerous employee health and safety protocols, including engineering and administrative controls, policies, procedures, processes, and training to minimize the potential for, and the severity of, work-related injuries and illnesses.

In 2022, the Company was able to reduce its work-related injury rate per 100 employees to 1.5%, a reduction of 6.3% over 2021. The Company maintained its work-related lost work injury rate per 100 employees at 0.3%. The Company completed a Corporate EHS Audit on 15 significant laboratory facilities, allowing it to assess locations against common expectations and performance criteria. In response to COVID-19, the Company modified the audit format so that it could be effectively performed virtually, with the added benefit of reducing audit travel-related greenhouse gas emissions.

In 2022, the Company faced extraordinary challenges in assisting the nearly 400 employees, and in many cases their families, who were adversely affected by the Ukraine/Russia crisis. In response, the Company supported employees with emergency, short- and long-term housing, transportation and relocation assistance, and provided help with communications, food, and other necessary supplies and services.

Community Engagement

The Labcorp Charitable Foundation, a private, charitable 501(c)(3) organization established by the Company, invested in more than 120 programs in 2022 that align with the Company’s strategic mission to improve health and improve lives in the areas of health, education, and community across the globe. The Foundation supports efforts to increase access to health services and create equitable opportunities for underserved populations across the globe.

Colleagues around the globe are invited to participate in the company’s annual Employee Giving Campaign. Through the campaign, colleagues had the opportunity to donate to one or more of seven selected charities: the American Cancer Society, American Heart Association, American Diabetes Association, American Red Cross (Disaster Relief), United Way, the National Urban League and new for 2022, Project HOPE. Employee contributions support these charities to provide needed services in

Index

their local communities and around the globe. The Labcorp Charitable Foundation offers a match opportunity for contributions made through the campaign.

In addition, the Company's employees took advantage of opportunities to support charitable causes and make a positive impact in their communities. For example, in honor of the life and legacy of Dr. Martin Luther King Jr., colleagues participated in the “Cards of Encouragement” campaign, a global initiative to lift the spirits of hospitalized children and their families. With the help of Cards for Hospitalized Kids, close to 8,000 cards were distributed to children and their families staying at Ronald McDonald Houses or receiving treatment at nonprofit children’s hospitals. The Labcorp Charitable Foundation made a financial donation to the 39 supported charities.

The Company's global colleagues also support the local communities where they live and work. In observation of Childhood Cancer Awareness Month, Company colleagues in Geneva, Switzerland supported ARFEC (Association Romande des Familles d’Enfants atteints d’un Cancer) to benefit hospitalized children and their families through toy drives, the creation and sale of a calendar and participation in the Geneva 20 kilometer race.

Dynacare, a Labcorp company based in Canada, teamed up with Diabetes Canada to organize the #Dyncare4Diabetes campaign for the second consecutive year. The campaign raises awareness of diabetes and provides accessible and free testing for at risk individuals. In addition to offering free hemoglobin A1C testing at all Dynacare laboratory locations across the Greater Toronto Area and at mobile community clinics, Dynacare donated 50 cents to Diabetes Canada for every individual that participated in the campaign, up to a total of $25,000.

Customers

The Company provides its services to a broad range of customers across Dx and DD. The primary customer groups serviced by the Company include:

•Health Plans. The Company serves many health plans, including MCOs and other health insurance providers, each of which operate on a national, regional, or local basis. In certain locations, health plans may delegate to independent physician associations (IPAs) or other alternative delivery systems (e.g., ACOs) the ability to negotiate for services on behalf of certain members.

•Pharmaceutical, Biotechnology, Medical Device, and Diagnostics Companies. The Company provides development services to hundreds of pharmaceutical, biotechnology, medical device, and diagnostics companies, ranging from the world's largest multi-nationals to emerging, small and mid-market companies.

•Physicians and Other Healthcare Providers. Physicians who require clinical laboratory testing for their patients are a primary source of requests for Dx's testing services.

•Hospitals and Health Systems. The Company provides hospitals and health systems with services ranging from core and specialty testing to supply chain and technical support services, and the opportunity to be a research partner for participation in studies and clinical trials with DD. In some cases, a hospital’s on-site laboratory may be operated or managed by an outside contractor or independent laboratory, including the Company.

•Other Customers. The Company serves a broad range of other customers, including, but not limited to, governmental agencies, employers, patients and consumers, CROs, crop protection and chemical companies, academic institutions, independent clinical laboratories, and retailers.

Sales, Marketing, and Customer Service

The Company offers its services through a sales force focused on serving the specific needs of customers in different market segments. The Company's sales force is responsible for both new sales and for customer retention and relationship building.

For Dx, these market segments generally include primary care, women's health, specialty medicine (e.g., infectious diseases, endocrinology, gastroenterology, and rheumatology), oncology, ACOs, and hospitals and health systems, with different representatives focused on each segment to better understand and respond to the unique needs of each clinical area. The DD global sales organization provides customer coverage across the pharmaceutical, biotechnology, and medical device industries for services including lead optimization, preclinical safety assessment, analytical services, clinical trials, central laboratories, biomarkers, and companion diagnostics, market access and technology solutions. As part of the Company's ongoing strategic priority to maximize the value of its unique leadership in both diagnostics and drug development, sales representatives from each business segment work together on outreach to potential customers of each business, including hospitals and health systems that may purchase testing and participate in clinical trials, or pharmaceutical, biotechnology or medical device companies whose studies may benefit from use of Dx’s specialty testing or network of PSCs.

Index

Market Opportunity

The Company believes that in 2022, the U.S. clinical laboratory testing industry generated revenues of more than $80 billion. The clinical laboratory industry consists primarily of three types of providers: hospital-based laboratories, physician-office laboratories, and independent clinical and anatomical pathology laboratories, such as those operated by Dx.

The clinical laboratory business is intensely competitive, and the Company believes that both competition and consolidation in the clinical laboratory business will continue. CMS has estimated that, as of February 2023, there were 9,165 hospital-based laboratories, 123,511 physician-office laboratories, and 9,411 independent clinical and anatomic pathology laboratories in the U.S. Dx competes with all of those laboratories. In addition, an increasing number of health system laboratories have been expanding their operations and business, resulting in greater competition for testing from physicians within those systems and from unaffiliated physicians in the health system laboratories’ service areas.

Dx believes that the selection of a laboratory is primarily based on the following factors, all of which the Company believes it competes favorably in:

•quality, timeliness, and consistency in reporting test results;

•reputation of the laboratory in the medical community or field of specialty;

•contractual relationships with MCOs;

•service capability and convenience;

•number and type of tests performed;

•connectivity solutions offered; and

•pricing of the laboratory’s services.

In addition to the factors listed above, the Company believes that the operational and economic efficiencies provided by its integrated service and logistics network, large-scale automated testing, and regular introduction of new technologies will allow the Company to compete effectively with other providers of laboratory services.

Drug development services companies like DD are also referred to as CROs and typically derive substantially all of their revenue from research and development (R&D), as well as marketing expenditures, of the pharmaceutical, biotechnology and medical device industries.

Outsourcing of R&D services to CROs has increased in the past, and is expected to continue increasing in the future. Increasing pressures to improve return on investment, to increase R&D productivity, to stay abreast of scientific advances and to comply with stringent government regulations and attempts to reduce and control the price of prescription drugs have all contributed to this outsourcing to CROs. A CRO provides clients with flexibility in aligning resources to demand. In the face of mounting complexity, the investment and amount of time required to develop new products are significant and have been increasing. These trends create opportunities for DD and other CROs that can help make the development process more efficient.

The drug development industry has many participants ranging from hundreds of small providers to a limited number of large CROs with global capabilities. DD competes against these small and large CROs, as well as in-house departments of pharmaceutical, biotechnology, medical device and diagnostic companies, and to a lesser extent, selected academic research centers, universities and teaching hospitals.

DD believes that customers selecting a CRO often consider the following factors, all of which the Company believes it competes favorably in:

•reputation for quality and regulatory compliance;

•efficient, timely performance;

•expertise and experience in operations;

•application of technology and innovation;

•specific therapeutic and scientific expertise;

•data and analytical capabilities;

•post-approval and market access services;

•ability to recruit patients;

•scope of service offerings;

•strengths in various geographic markets;

•price;

Index

•quality of facilities;

•quality of relationships, including investigator and patient;

•ability to manage large-scale clinical trials both domestically and internationally, including the recruitment of appropriate and sufficient clinical trial subjects;

•size and scale;

•decentralized clinical trial capabilities;

•ability to develop companion diagnostics; and

•access to talent.

Quality

Dx and DD have comprehensive quality systems and processes appropriate for their respective businesses. The Company's quality programs are overseen by Dx's National Office of Quality, DD’s Global Regulatory Compliance and Quality Assurance Unit, DD's clinical trial services global vendor management department, DD's central laboratory services expanded laboratory management services department, and the Company's global supply chain management department and project management staff. The Company has procedures for monitoring its internal performance, as well as that of its vendors, suppliers, and other key stakeholders. In addition, various groups and departments within the Company provide oversight to monitor and control vendor products and performance, and play an essential role in the Company’s approach to quality through improvements in processes and automation.

Virtually all facets of the Company’s services are subject to quality programs and procedures, including accuracy and reproducibility of tests, turnaround time, customer service, data integrity, patient satisfaction, and billing. The Company’s quality programs include measures that compare current performance against desired performance goals to monitor critical aspects of service to its customers and patients. This includes licensing, credentialing, training and competency of professional and technical staff, and internal auditing. In addition to the Company's own quality programs, the Company’s laboratories, facilities and processes are subject to on-site regulatory agency inspections and accreditation evaluations, in addition to surveys and proficiency testing, by local or national government agencies; independent external accrediting programs; and inspections and audits by customers.

Thirty-three of the Company's laboratories have received ISO 15189 and/or ISO 13485 accreditation, demonstrating that they meet international standards for quality and technical competence.

Information Systems

The Company is committed to developing and commercializing technology-enabled solutions to support its operations and provide better care. The Company operates standard platforms for its core business services and its financial and reporting systems. These standard systems provide consistency within workflows and information as well as a high level of system availability, security, and stability. The primary laboratory systems include standardized support for molecular diagnostics, digital pathology and enhanced specialty laboratory solutions. The Company's centralized information systems are responsible for operational efficiencies, enabling the Company to achieve consistent, structured, and standardized operating results and effective patient care.

The information systems used by Dx and DD are discussed in more detail in the sections dedicated to each of those segments.

Intellectual Property Rights

The Company relies on a combination of patents, trademarks, copyrights, trade secrets, and nondisclosure and non-competition agreements to establish and protect its proprietary technology. The Company has filed and obtained numerous patents in the U.S. and abroad, and regularly files patent applications, when appropriate, to establish and protect its proprietary technology. Occasionally, the Company also licenses U.S. and non-U.S. patents, patent applications, technology, trade secrets, know-how, copyrights or trademarks owned by others. The Company believes, however, that no single patent, technology, trademark, intellectual property asset or license is material to its business as a whole.

Patents covering the Company's technologies are subject to challenges. Issued patents may be successfully challenged, invalidated, circumvented, or declared unenforceable so that patent rights would not create an effective competitive barrier. In addition, the laws of some countries may not protect proprietary rights to the same extent as do the laws of the U.S.

Parties may file claims asserting that the Company's technologies infringe on their intellectual property. The Company cannot predict whether parties will assert such claims against it, or whether those claims will harm its business. If the Company is forced to defend against such claims, the Company could face costly litigation and diversion of management’s attention and resources. As result of such disputes, the Company may have to develop costly non-infringing technology or enter into licensing agreements. These agreements, if necessary, may require financial or other terms that could have an adverse effect on

Index

the Company's business and financial condition.

Regulation and Reimbursement

General

Because the Company operates in a number of distinct environments and in a variety of locations worldwide, it is subject to numerous, and sometimes overlapping, regulatory requirements. Both the clinical laboratory industry and the drug development business are subject to significant governmental regulation at the national, state and local levels. As described below, these regulations concern licensure and operation of clinical laboratories, claim submission and reimbursement for laboratory services, healthcare fraud and abuse, drug development services, security and confidentiality of health information, quality, and environmental and occupational safety.

Regulation of Clinical Laboratories

Virtually all clinical laboratories operating in the U.S. must be certified by the federal government or by a federally approved accreditation agency. In most cases, that certification is regulated by CMS through CLIA, which requires that applicable clinical laboratories meet quality assurance, quality control, and personnel standards. Laboratories also must undergo proficiency testing and are subject to inspections. Clinical laboratories in locations other than the U.S. are generally subject to comparable regulation in their respective jurisdictions.

Standards for testing under CLIA are based on the complexity of the tests performed by the laboratory, with tests classified as “high complexity,” “moderate complexity,” or “waived.” Laboratories performing high-complexity testing are required to meet more stringent requirements than moderate-complexity laboratories. Laboratories performing only waived tests, which are tests determined by the FDA to have a low potential for error and requiring little oversight, may apply for a certificate of waiver exempting them from most CLIA requirements. All major and many smaller Company facilities hold CLIA certificates to perform high-complexity testing. The Company's remaining smaller testing sites hold CLIA certificates to perform moderate-complexity testing or a certificate of waiver. The sanctions for failure to comply with CLIA requirements include suspension, revocation, or limitation of a laboratory's CLIA certificate, which is necessary to conduct business; cancellation or suspension of the laboratory's approval to receive Medicare and/or Medicaid reimbursement; as well as significant fines and/or criminal penalties. The loss or suspension of a CLIA certification, imposition of a fine or other penalties, or future changes in the CLIA law or regulations (or interpretation of the law or regulations) could have a material adverse effect on the Company.

The Company is also subject to state and local laboratory regulation. CLIA provides that a state may adopt laboratory regulations different from or more stringent than those under federal law, and a number of states have implemented their own laboratory regulatory requirements. State laws may require that laboratory personnel meet certain qualifications, specify certain quality controls, or require maintenance of certain records.

The Company believes that it is in compliance in all material respects with all laboratory requirements applicable to its laboratories operating both within the U.S. and in other countries. The Company's laboratories have continuing programs to maintain operations in compliance with all such regulatory requirements, but no assurances can be given that the Company's laboratories will pass all future licensure or certification inspections.

FDA and Other Regulatory Agency Laws and Regulations

Various regulatory agencies, including CMS and the FDA in the U.S., regulate the development, testing, manufacturing, labeling, advertising, marketing, distribution, storage, import, export, performance, and surveillance of diagnostic and therapeutic products and services, including certain products and services offered by the Company and the development of therapeutic products that comprise the majority of DD’s business. The FDA and other regulatory agencies periodically inspect and review the manufacturing processes and product performance of diagnostic and therapeutic products, while CMS, certain state programs, and accreditation entities inspect and review the facilities, personnel, and procedures of clinical laboratories and their laboratory operations. The FDA and other regulatory agencies also periodically inspect clinical study sites and CROs that conduct clinical trials, including test facilities that perform tests on samples from human subjects enrolled in such clinical studies of drugs, biologics, and medical devices. These agencies have the authority to take various administrative and legal actions for noncompliance, such as fines, withdrawal of product approval, warning or untitled letters, seizures, recalls, injunctions, and other civil and criminal sanctions.

Since 2014, there have been ongoing discussions and advocacy between stakeholders, including the clinical laboratory industry, the FDA, and Congress, about potential FDA regulation of laboratory-developed tests (LDTs), which are assays developed and performed in-house by clinical laboratories and can be made available to the public without pre-market review by the FDA (although COVID-19 diagnostic PCR LDTs have been subject to FDA pre-market requirements as a consequence of the national health emergency). Various regulatory and legislative proposals are under consideration, including some that

could increase general FDA oversight of clinical laboratories and LDTs. The outcome and ultimate impact of such proposals on the Company is difficult to predict at this time.

There are similar national and regional regulatory agencies, and regulations, in the jurisdictions outside of the U.S. in which the Company operates. For example, the European Union In Vitro Diagnostics Regulation (Regulation (EU) 2017/746 (EU IVDR)), which became applicable May 26, 2022, established a new legislative framework for in vitro diagnostic devices including a rule-based classification and quality and safety standards. In addition, both Switzerland and the United Kingdom are implementing new legislative frameworks similar to the EU IVDR.

DD’s laboratory facilities and Dx's clinical laboratory facilities that perform testing in support of clinical trials, must conform to a range of standards and regulations, including good laboratory practice (GLP) and good clinical practice (GCP), good manufacturing practice (cGMP), human subject protection and investigational product exemption regulations, and quality system regulation (QSR) requirements, as applicable. The preclinical and clinical studies that the Company conducts are subject to periodic inspections by the FDA as well as other regulatory agencies in the jurisdictions outside the U.S. in which the Company operates, which may include, without limitation, the Medicines and Healthcare products Regulatory Agency (MHRA) in the U.K., the European Medicines Agency, the National Medical Products Administration in China, and the Pharmaceuticals and Medical Devices Agency in Japan, to determine compliance with GLP and GCP as well as other applicable standards and regulations. If a regulatory agency determines during an inspection that the Company’s equipment, facilities, laboratories, operations, or processes do not comply with applicable regulations and GLP and/or GCP standards, the regulatory agency may issue a formal notice (FDA Form 483), which may be followed by a warning letter if observations are not addressed satisfactorily. Noncompliance may result in, among other things, unanticipated compliance expenditures, or the regulatory agency seeking civil, criminal or administrative sanctions and/or remedies against the Company, including suspension of its operations.

The FDA Modernization Act 2.0 was enacted in December 2022 as Section 3209 of the Consolidated Appropriations Act, 2023. This Act amended Section 505 of the Federal Food, Drug and Cosmetic Act (21 U.S.C. 355) to clarify the methods manufacturers and sponsors can use to investigate the safety and efficacy of a drug or the toxicity of a bioisimilar biologic product to include tests on animals as well as certain tests that are not performed on animals. Specifically, the Act replaces a statutory reference to “tests on animals” as a viable option for pre-clinical testing with a reference to “nonclinical tests”, which includes animal testing, cell-based assays, microphysiological systems, or bioprinted or computer models. The Act does not eliminate animal testing or require the use of non-animal models. FDA previously had the authority to allow non-animal data to be considered during safety and efficacy reviews of new drugs and had previously issued related guidance. However, many procedures intended to reduce animal tests are still in various stages of development. Since such alternative methodologies must first be validated before FDA will approve of their use instead of validated animal models, the practical impact of the Act is likely to be limited for some time.

Additionally, certain DD services and activities, such as chemistry, manufacturing, and controls (CMC) services and manufacturing of investigational medicinal products for use in certain Phase I studies managed by DD, must conform to cGMP. DD is subject to periodic inspections by the FDA and the MHRA, as well as other regulatory agencies in the jurisdictions outside the U.S. in which the Company operates, in order to assess, among other things, cGMP compliance. If a regulatory agency identifies deficiencies during an inspection, it may issue a formal notice, which may be followed by a warning letter if observations are not addressed satisfactorily. Failure to maintain compliance with cGMP regulations and other applicable requirements of various regulatory agencies could result in, among other things, fines, warnings or untitled letters, unanticipated compliance expenditures, suspension of manufacturing, enforcement actions, product seizures or recalls, injunctions, or criminal prosecution.

Some Dx products are regulated by the FDA and other similar national regulatory agencies as medical devices. The FDA defines a medical device in part as an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article which is intended for the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease in man. FDA regulates the development, testing, manufacturing, marketing, post‑market surveillance, distribution, advertising and labeling of products classified as medical devices separate from clinical diagnostic testing services offered under CLIA requirements. FDA regulatory requirements include: all of the relevant elements of the Quality System Regulation (which requires manufacturers to follow stringent design, testing, control, documentation and other quality assurance procedures), labeling regulations, restrictions on promotion and advertising, Medical Device Reporting regulations (which requires the manufacturer to report to the FDA if its device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur), the Reports of Corrections and Removals regulations (which requires manufacturers to report certain recalls and field actions to the FDA), and other post-market requirements.

To ensure compliance with regulatory requirements, medical device manufacturers are subject to market surveillance and periodic, pre-scheduled and unannounced inspections by the FDA. Failure to comply with applicable regulatory requirements

Index

can result in enforcement action by the FDA, which may include sanctions, operating restrictions, partial suspension or total shutdown of production; refusal to grant clearance or approvals of new devices; withdrawal of clearance or approval; and civil or criminal prosecution.

Animal Welfare Laws and Regulations

The conduct of animal research at DD’s facilities in the U.S. must be in compliance with the Animal Welfare Act (AWA), which governs the care and use of warm-blooded animals for research in the U.S. other than laboratory rats, mice, and chickens, and is enforced through periodic inspections by the U.S. Department of Agriculture (USDA). The AWA establishes facility standards regarding several aspects of animal welfare, including housing, ventilation, lighting, feeding and watering, handling, veterinary care, and recordkeeping. DD complies with licensing and registration requirement standards set by the USDA and similar agencies in foreign jurisdictions such as the European Union, the U.K., and China for the care and use of regulated species. If the USDA determines that DD’s equipment, facilities, laboratories or processes do not comply with applicable AWA standards, it may issue an inspection report documenting the deficiencies and setting deadlines for any required corrective actions. The USDA may impose fines, suspend and/or revoke licenses and registrations, or confiscate research animals. Other countries where the Company conducts business have similar laws and regulations with which the Company must also comply. In addition, certain of DD’s animal-related activities may be subject to regulation by the U.S. Centers for Disease Control and Prevention (CDC), the Office of Laboratory Animal Welfare of the National Institutes of Health, the U.S. Fish and Wildlife Service, and similar organizations in other jurisdictions.

Payment for Clinical Laboratory Services

In 2022, Dx derived approximately 10.8% of its revenue directly from traditional Medicare and Medicaid programs. In addition, Dx's other commercial laboratory testing business that is not directly related to Medicare or Medicaid nevertheless depends significantly on continued participation in these programs and in other government healthcare programs, in part because customers often want a single laboratory to perform all of their testing services. In recent years, both governmental and private-sector payers have made efforts to contain or reduce healthcare costs, including reducing reimbursement for clinical laboratory services.

Reimbursement under the Medicare PFS is capped at different rates in each Medicare Administrative Contractor's jurisdiction. Pursuant to PAMA, unless modified by Congress, reimbursement under the CLFS is set at a national rate that is updated every three years for most tests. State Medicaid programs are prohibited from paying more than the Medicare fee schedule limit for clinical laboratory services furnished to Medicaid recipients. Laboratories primarily bill and are reimbursed by Medicare and Medicaid directly for covered tests performed on behalf of Medicare and Medicaid beneficiaries. For beneficiaries that participate in Managed Medicare and Managed Medicaid plans, laboratory bills are submitted to and paid by MCOs that manage those plans. Approximately 8.9% of Dx's revenue is reimbursed directly by Medicare under the CLFS.

Many pathology services performed by Dx are reimbursed by Medicare under the PFS. The PFS assigns relative value units to each procedure or service, and a conversion factor is applied to calculate the reimbursement. The PFS is also subject to adjustment on an annual basis. Such adjustments can impact both the conversion factor and relative value units. The Sustainable Growth Rate (SGR), the formula previously used to calculate the fee schedule conversion factor, would have resulted in significant decreases in payment for most physician services for each year since 2003. However, Congress intervened repeatedly to prevent these payment reductions, and the conversion factor was increased or frozen for the subsequent year. The Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) permanently replaced the SGR formula and transitioned PFS reimbursement to a value-based payment system. MACRA retroactively avoided a 21.2% reduction in PFS reimbursement that had been scheduled for April 1, 2015, and provided for PFS conversion factor increases of 0.5% from July 1, 2015 to December 31, 2015, and 0.5% in each of years 2016-2019, followed by no updates for 2020 through 2025, and updates that vary based on participation in alternative payment models in subsequent years. These changes to the conversion factor may be offset by reductions to the relative value units, as was the case with the 2016 PFS reductions. For 2022, Congress increased the conversion factor by 3.0% over the amount announced in the final rule, instead of allowing a 3.75% reduction to take effect. In the Consolidated Appropriations Act of 2023, Congress mitigated PFS cuts in 2023 and 2024 by 2.5% and 1.25%, respectively, that would otherwise have been (4.47%) in 2023 based on the conversation factor put forward in the 2023 Medicare Physician Fee Schedule final rule. Approximately 0.4% of Dx's revenue is reimbursed under the PFS.

In addition to changes in reimbursement rates, Dx is also impacted by changes in coverage policies for laboratory tests and annual CPT coding revisions. Medicare, Medicaid and private payer diagnosis code requirements and payment policies negatively impact Dx's ability to be paid for some of the tests it performs. Further, some payers require additional information to process claims, employ third-party utilization management tools, or have implemented prior authorization policies which delay or prohibit payment. In 2022, there were limited coding and billing changes. While limited changes are expected to be implemented in 2023, the Company typically expects some delays in pricing and reimbursement as new codes are introduced.

Index

Future changes in national, state and local laws and regulations (or in the interpretation of current regulations) affecting government payment for clinical laboratory testing could have a material adverse effect on the Company.

Further healthcare reform could occur in 2023, including changes to the ACA and Medicare reform, as well as administrative requirements that may continue to affect coverage, reimbursement, and utilization of laboratory services in ways that are currently unpredictable.

Privacy, Security and Confidentiality of Health Information and Other Personal Information

In the U.S., the Health Insurance Portability and Accountability Act of 1996 (HIPAA) was designed to address issues related to the security and confidentiality of health information and to improve the efficiency and effectiveness of the healthcare system by facilitating the electronic exchange of information in certain financial and administrative transactions. These regulations apply to health plans and healthcare providers that conduct standard transactions electronically and healthcare clearinghouses (covered entities). Six such regulations include: (i) the Transactions and Code Sets Rule; (ii) the Privacy Rule; (iii) the Security Rule; (iv) the Standard Unique Employer Identifier Rule; (v) the National Provider Identifier Rule; and (vi) the Health Plan Identifier Rule. The Company, which may act as a HIPAA covered entity in certain circumstances, believes that it is in compliance in all material respects with each of the HIPAA Rules identified above.

The Privacy Rule regulates the use and disclosure of protected health information (PHI) by covered entities. It also sets forth certain rights that an individual has with respect to his or her PHI maintained by a covered entity, such as the right to access or amend certain records containing PHI or to request restrictions on the use or disclosure of PHI. The Privacy Rule requires covered entities to contractually bind third parties, known as business associates, in the event that they perform an activity or service for or on behalf of the covered entity that involves the creation, receipt, maintenance, or transmission of PHI.

On February 6, 2014, CMS and HHS published final regulations that amended the HIPAA Privacy Rule to provide individuals (or their personal representatives) with the right to receive copies of their test reports from laboratories subject to HIPAA, or to request that copies of their test reports be transmitted to designated third parties.

On December 12, 2018, HHS issued a request for information (RFI) seeking input from the public on how the HIPAA regulations and the Privacy Rule, in particular, could be modified to amend existing, or impose additional, obligations relating to the processing of PHI. Subsequent to the RFI, on January 21, 2021, HHS published a notice of proposed rulemaking (NPRM) containing potential modifications to the Privacy Rule addressing standards that may impede the transition to value-based healthcare and strengthen individuals' rights to access their health information. The public comment period for the NPRM was closed on May 6, 2021. The Company is monitoring the NPRM process. If modifications to the Privacy Rule are adopted, they may impact the Company's compliance obligations under HIPAA.

The U.S. Health Information Technology for Economic and Clinical Health Act (HITECH), which was enacted in February 2009, with regulations effective on September 23, 2013, strengthened and expanded the HIPAA Privacy and Security Rules and their restrictions on use and disclosure of PHI. HITECH includes, but is not limited to, prohibitions on exchanging PHI for remuneration and additional restrictions on the use of PHI for marketing. HITECH also fundamentally changes a business associate’s obligations by imposing a number of Privacy Rule requirements and a majority of Security Rule provisions directly on business associates that were previously only directly applicable to covered entities. Moreover, HITECH requires covered entities to provide notice to individuals, HHS, and, as applicable, the media when unsecured PHI is breached, as that term is defined by HITECH. Business associates are similarly required to notify covered entities of a breach.

The administrative simplification provisions of HIPAA mandate the adoption of standard unique identifiers for healthcare providers. The intent of these provisions is to improve the efficiency and effectiveness of the electronic transmission of health information. The National Provider Identifier Rule requires that all HIPAA-covered healthcare providers, whether they are individuals or organizations, must obtain an NPI to identify themselves in standard HIPAA transactions. NPI replaces the unique provider identification number and other provider numbers previously assigned by payers and other entities for the purpose of identifying healthcare providers in standard electronic transactions.

Violations of the HIPAA provisions could result in civil and/or criminal penalties, including significant fines and up to 10 years in prison. HITECH also significantly strengthened HIPAA enforcement by increasing the civil penalty amounts that may be imposed, requiring HHS to conduct periodic audits to confirm compliance and authorizing state attorneys general to bring civil actions seeking either injunctions or damages in response to violations of the HIPAA privacy and security regulations that affect the privacy of state residents.

The total cost associated with meeting the ongoing requirements of HIPAA and HITECH is not expected to be material to the Company’s operations or cash flows. However, future regulations and interpretations of HIPAA and HITECH could impose significant costs on the Company.

The information blocking provisions (Information Blocking Rules) of the 21st Century Cures Act became effective on April

Index

5, 2021. The Information Blocking Rules prohibit covered actors, including healthcare providers, from engaging in activity that is likely to interfere with the access, exchanges, or use of electronic health information (EHI) unless such activity falls into one of eight exceptions. The Information Blocking Rules provide for civil monetary penalties for noncompliance by healthcare IT vendors and, separately, “appropriate disincentives” for noncompliance by healthcare providers. The Company believes that it is in compliance in all material respects with the requirements of the Information Blocking Rules.

In addition to the regulations described above, numerous other data protection, privacy and similar laws govern the confidentiality, security, use, and disclosure of personal information, as well as breach notification responsibilities. These laws vary by jurisdiction, but they most commonly regulate or restrict the collection, use, and disclosure of medical and financial information and other personal information. In the U.S., the Federal Trade Commission (FTC) has authority to regulate unfair or deceptive acts or practices, including with respect to data privacy and security. If the Company’s public statements about collection, use or disclosure of personal information are perceived to be inconsistent with the Company’s actual practices, the Company may face accusations of unfairness or deception under the FTC Act or state law equivalents. In addition, some state laws are more restrictive and, therefore, are not preempted by HIPAA. Penalties for violation of these laws may include sanctions against a laboratory's licensure, as well as civil and/or criminal penalties.

Congress and state legislatures also have been implementing new legislation relating to privacy and data protection. For example, on June 28, 2018, the California legislature passed the California Consumer Privacy Act (CCPA), which became effective January 1, 2020. The CCPA created transparency requirements and granted California residents several new rights with regard to their personal information. In addition, in November 2020, California voters approved the California Privacy Rights Act (CPRA) ballot initiative, which introduced significant amendments to the CCPA and established and funded a dedicated California privacy regulator, the California Privacy Protection Agency (CPPA). The amendments introduced by the CPRA went into effect on January 1, 2023, and new implementing regulations are expected to be introduced by the CPPA. Failure to comply with the CCPA may result in, among other things, significant civil penalties and injunctive relief, or potential statutory or actual damages. In addition, California residents have the right to bring a private right of action in connection with certain types of incidents. These claims may result in significant liability and potential damages. Other states have passed legislation similar to the CCPA, including the Virginia Consumer Data Protection Act (VCDPA), which became effective January 1, 2023, the Colorado Privacy Act (CPA) and the Connecticut Data Privacy Act (CTDPA), both effective July 1, 2023, and the Utah Consumer Privacy Act (UCPA), effective December 31, 2023. The VCDPA, CPA, CTDPA, and UCPA heavily mirror the principles and requirements of the CCPA; however, these laws do not provide for a private right of action. The Company continues to assess the impact of these laws on the Company’s business, and the Company is implementing and will prepare to implement appropriate processes to manage compliance with these laws as they become effective and more guidance is provided.

Effective August 14, 2020, the Substance Abuse and Mental Health Services Administration of HHS (SAMHSA) announced the finalization of proposed changes to the Confidentiality of Substance Use Disorder Patient Records regulation, 42 Code of Federal Regulations Part 2. This regulation protects the confidentiality of patient records relating to the identity, diagnosis, prognosis, or treatment that are maintained in connection with the performance of any federally assisted program or activity relating to substance use disorder education, prevention, training, treatment, rehabilitation, or research. Under the regulation, patient identifying information may only be released with the individual’s written consent, subject to certain limited exceptions. The latest changes to this regulation seek to better facilitate care coordination, while maintaining more stringent confidentiality of substance use disorder information. The Company adopted changes to its policies and procedures necessary for compliance.

The European Union General Data Protection Regulation (GDPR) Regulation (EU) 2016/679, became effective May 25, 2018, replacing Directive 95/46/EC. The GDPR established requirements applicable to the use and transfer of personal data and imposes penalties for noncompliance of up to the greater of €20 million or 4% of worldwide revenue. The GDPR, as well as the U.K.'s implementation - the U.K. General Data Protection Regulation - requires transparency with regard to the means and purposes of processing of personal data; collection of consent to process personal data in certain circumstances; the ability to provide records of processing upon request by a supervisory authority or data controller; implementation of appropriate technical and organizational measures to maintain security of personal data; notification of personal data breaches to supervisory authorities, data controllers, and individuals within expedient time frames; and performance of data protection impact assessments for certain processing activities. The GDPR also provides individual data subjects with certain rights, where applicable, including the right of access, the right to rectification, the right to be forgotten, the right to restrict or object to processing, and the right to data portability. The GDPR requires that personal data may only be transferred outside of the European Union to a country that offers an adequate level of data protection under standards set by the European Union, or where such transfer is otherwise pursuant to a legal framework approved by the European Union. On July 16, 2020, the Court of Justice of the European Union (CJEU) released its decision in Data Protection Commission v. Facebook Ireland Limited, Maximillian Schrems (Schrems II), which invalidated the EU-U.S. Privacy Shield as a legal framework for the transfer of personal data outside of the European Union, and suggesting additional safeguards for the use of Standard Contractual Clauses

Index

(SCCs) as a legal framework for the transfer of personal data outside of the European Union. On June 4, 2021, the European Commission release updated SCCs, which, in part, adopted many of the additional safeguards highlighted in the Schrems II decision. Companies using SCCs for the transfer of personal data outside of the European Union are required to use the new SCCs for new transfers of personal data as of September 27, 2021, and for all transfers of personal data as of December 27, 2022. The Company has established processes and frameworks to manage compliance with the GDPR and other global privacy and data protection requirements, and to manage preparation for future enacted regulations. Compliance could impose significant costs on the Company.

In addition to the GDPR, numerous other countries have laws governing the collection, use, disclosure, and transmission (including cross-border transfer) of personal information, including medical information. The legislative and regulatory landscape for privacy and data protection is complex and continually evolving. Data protection regulations have been enacted or updated in regions where the Company does business including in Asia, Latin America, and Europe, and in countries such as Canada, India, and the UK. Failure to comply with these regulations may result in, among other things, civil, criminal and contractual liability, fines, regulatory sanctions and damage to the Company’s reputation.

Fraud and Abuse Laws and Regulations

Existing U.S. laws governing federal healthcare programs, including Medicare and Medicaid, as well as similar state laws, impose a variety of broadly described fraud and abuse prohibitions on healthcare providers, including clinical laboratories. These laws are interpreted liberally and enforced aggressively by multiple government agencies, including the U.S. Department of Justice, OIG and various state agencies. Historically, the clinical laboratory industry has been the focus of major governmental enforcement initiatives. The U.S. government's enforcement efforts have been conducted under statutory authorities such as those contained in HIPAA, which includes several provisions related to fraud and abuse enforcement, including the establishment of a program to coordinate and fund U.S., state and local law enforcement efforts, and in the Deficit Reduction Act of 2005, which included requirements directed at Medicaid fraud, including increased spending on enforcement and financial incentives for states to adopt false claims act provisions similar to the U.S. False Claims Act. Amendments to the False Claims Act, and other enhancements to the U.S. fraud and abuse laws enacted as part of the ACA, have further increased fraud and abuse enforcement efforts and compliance risks. For example, the ACA established an obligation to report and refund overpayments from Medicare or Medicaid within 60 days of identification (whether or not paid through any fault of the recipient); failure to comply with this requirement can give rise to additional liability under the False Claims Act and Civil Monetary Penalties statute.

The U.S. Anti-Kickback Statute prohibits knowingly providing anything of value in return for, or to induce the referral of, Medicare, Medicaid or other U.S. federal healthcare program business. Violations can result in imprisonment, fines, penalties, and/or exclusion from participation in U.S. federal healthcare programs. The OIG has published “safe harbor” regulations that specify certain arrangements that are protected from prosecution under the Anti-Kickback Statute if all conditions of the relevant safe harbor are met. Failure to fit within a safe harbor does not necessarily constitute a violation of the Anti-Kickback Statute; rather, the arrangement would be subject to scrutiny by regulators and prosecutors and would be evaluated on a case-by-case basis. Many states have their own Medicaid anti-kickback laws, and several states also have anti-kickback laws that apply to all payers (i.e., not just government healthcare programs).

From time to time, the OIG issues alerts and other guidance on certain practices in the healthcare industry that implicate the Anti-Kickback Statute or other fraud and abuse laws. OIG Special Fraud Alerts and Advisory Opinions relevant to the Company set forth a number of practices allegedly engaged in by some clinical laboratories and healthcare providers that raise issues under the U.S. fraud and abuse laws, including the Anti-Kickback Statute. These practices include: (i) providing employees to furnish valuable services for physicians (other than collecting patient specimens for testing) that are typically the responsibility of the physicians’ staff; (ii) offering or providing discounted laboratory services billed to referral sources in return for referrals of other tests that are billed to U.S. federal healthcare programs; (iii) providing free testing to physicians’ managed care patients in situations where the referring physicians benefit from such reduced laboratory utilization; (iv) providing free pickup and disposal of biohazardous waste for physicians for items unrelated to a laboratory’s testing services; (v) providing general-use facsimile machines or computers to physicians that are not exclusively used in connection with the laboratory services; (vi) providing free testing for healthcare providers, their families and their employees (i.e., so-called “professional courtesy” testing); (vii) rental of space in physician offices by equipment suppliers or other healthcare entities to which the physicians make referrals; (viii) compensation paid by laboratories to physicians and hospitals for blood specimen processing and for submitting patient data to registries; and (ix) remuneration provided to physicians and other health care professionals by pharmaceutical and medical device companies in connection with company-sponsored speaker programs.

In addition to the Anti-Kickback Statute, in October 2018, the U.S. enacted the Eliminating Kickbacks in Recovery Act of 2018 (EKRA), as part of the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (SUPPORT Act). EKRA is an all-payer anti-kickback law that makes it a criminal offense to pay any remuneration to induce referrals to, or in exchange for, patients using the services of a recovery home, a substance use clinical

Index

treatment facility, or laboratory. Although it appears that EKRA was intended to reach patient brokering and similar arrangements to induce patronage of substance use recovery and treatment, the language in EKRA is broadly written. As drafted, an EKRA prohibition on incentive compensation to sales employees is inconsistent with the federal anti-kickback statute and regulations, which permit payment of employee incentive compensation, a practice that is common in the industry. Significantly, EKRA permits the U.S. Department of Justice to issue regulations clarifying EKRA’s exceptions or adding additional exceptions, but such regulations have not yet been issued, and there is no additional DOJ or other government guidance to indicate how and to what extent it will be applied and enforced in the industry. The Company is working through its trade association to address the scope of EKRA.

Under another U.S. statute, known as the Stark Law or “physician self-referral” prohibition, physicians who have a financial or a compensation relationship with a clinical laboratory may not, unless an exception applies, refer Medicare or Medicaid patients for testing to the laboratory, regardless of the intent of the parties. Similarly, laboratories may not bill Medicare or Medicaid for services furnished pursuant to a prohibited self-referral. There are several Stark Law exceptions that are relevant to arrangements involving clinical laboratories, including: (i) fair market value compensation for the provision of items or services; (ii) payments by physicians to a laboratory for clinical laboratory services; (iii) ancillary services (including laboratory services) provided within the referring physician's own office, if certain criteria are satisfied; (iv) physician investment in a company whose stock is traded on a public exchange and has stockholder equity exceeding $75.0 million; and (v) certain space and equipment rental arrangements that are set at a fair market value rate and satisfy other requirements. Many states have their own self-referral laws as well, which in some cases apply to all patient referrals, not just government reimbursement programs.

In December 2020, the OIG and CMS published final rules to amend certain regulations implementing the Anti-Kickback Statute and the Stark Law, respectively. The amendments were primarily intended to alleviate perceived impediments to coordinated care and value-based compensation arrangements through new safe harbors to the Anti-Kickback Statute and new exceptions to the Stark Law, and have varying degrees of applicability to laboratories. The CMS final rule incorporates laboratories and permits support for value-based arrangements, under certain conditions for purposes of the Stark Law. However, the OIG final rule generally excludes laboratories from protection under the Anti-Kickback Statute safe harbors for value-based arrangements.

There are a variety of other types of U.S. and state fraud and abuse laws, including laws prohibiting submission of false or fraudulent claims and that require certain companies to disclose payments and other transfers of value to certain healthcare professionals and providers. The Company seeks to conduct its business in compliance with all U.S. and state fraud and abuse laws. The Company is unable to predict how these laws will be applied in the future, and no assurances can be given that its arrangements will not be subject to scrutiny under such laws. Sanctions for violations of these laws may include exclusion from participation in Medicare, Medicaid, and other U.S. or state healthcare programs, significant criminal and civil fines and penalties, and loss of licensure. Any exclusion from participation in a U.S. healthcare program, or material loss of licensure, arising from any action by any federal or state regulatory or enforcement authority, would likely have a material adverse effect on the Company's business. In addition, any significant criminal or civil penalty resulting from such proceedings could have a material adverse effect on the Company's business.

Enrollment and re-enrollment in U.S. healthcare programs, including Medicare and Medicaid, are subject to certain program integrity requirements intended to protect the programs from fraud, waste, and abuse. In September 2019, CMS published a final rule implementing program integrity enhancements to provider enrollment requiring Medicare, Medicaid, and Children’s Health Insurance Program (CHIP) providers and suppliers to disclose on an enrollment application or a revalidation application any current or previous direct or indirect affiliation with a provider or supplier that (i) has uncollected debt; (ii) has been or is subject to a payment suspension under a federal health care program; (iii) has been or is excluded by the OIG from Medicare, Medicaid, or CHIP, or (iv) has had its Medicare, Medicaid, or CHIP billing privileges denied or revoked. This rule permits CMS to deny enrollment based on such an affiliation when CMS determines that the affiliation poses an undue risk of fraud, waste, or abuse. CMS is phasing in this new affiliation disclosure requirement.

In November 2021, CMS published a final rule for the 2022 Medicare Physician Fee Schedule, which included further program integrity requirements. CMS finalized its proposal to expand the categories of parties within the purview of the denial and revocation provisions to include excluded administrative or management services personnel who furnish services payable by a federal healthcare program, such as a billing specialist, accountant, or human resources specialist. CMS also codified the billing privilege deactivation rebuttal process, under which a provider or supplier would have 15 calendar days from receipt of written notice of a deactivation to submit a rebuttal, and CMS could, in its discretion, extend the 15-day period to account for certain special situations. In addition, CMS defined factors it would use to determine whether revocation or suspension of billing privileges is appropriate due to a pattern or practice of non-compliant billing, which would be: (i) the percentage of submitted claims that were denied during the period under consideration; (ii) whether the provider or supplier has any history of final adverse actions and the nature of any such actions; (iii) the type of billing non-compliance and the specific facts surrounding said non-compliance (to the extent this can be determined); and (iv) any other information regarding the provider's

Index

or supplier's specific circumstances that CMS deems relevant to the determination. This is a reduction in the number of factors that were previously considered and a revision of some previous factors.

Environment, Health, and Safety

The Company is subject to licensing and requirements under laws and regulations relating to the protection of the environment, and employee health and safety. These laws and regulations include the safe handling, use, transportation and disposal of potentially infectious and hazardous materials; the assessment of potential work-related risks and establishment of work practice and engineering controls, and providing protective clothing and equipment, training, and medical surveillance; designed to minimize risk to employee health and safety and the environment.

The Company is committed to reducing its carbon footprint. The Company participates in the Carbon Disclosure Project (CDP) and the EcoVadis sustainable procurement rating processes. In December 2022, the Company submitted science-based targets to the Science Based Target Institute. Energy-saving measures at Company facilities include for example, installation of more efficient boilers, chillers, ventilation systems and LED lighting, engaging in waste-to-energy disposition, and reducing waste going to landfills. Funding for these and similar projects continued through 2022 and is expected to continue through 2023.

The Company seeks to comply with all relevant environment, employee health and safety laws and regulations. Failure to comply could subject the Company to various administrative and/or other enforcement actions.

Drug Testing

Drug testing for public sector employees is regulated by the SAMHSA, which has established detailed performance and quality standards that laboratories must meet to be approved to perform drug testing on employees of U.S. government contractors and certain other entities. To the extent that the Company’s laboratories perform such testing, each must be certified as meeting SAMHSA standards. The Company’s laboratories in Research Triangle Park, North Carolina; Raritan, New Jersey; Houston, Texas; Southaven, Mississippi; and St. Paul, Minnesota are all SAMHSA certified.

Controlled Substances

DD handles controlled substances as part of the services it provides in preclinical testing and clinical trials. The use of controlled substances in testing for drugs of abuse is regulated by the U.S. Drug Enforcement Administration under the Controlled Substances Act (CSA) and its implementing regulations. The CSA establishes, among other things, certain registration, security, recordkeeping, reporting, import, export and other requirements for controlled substances. The Company seeks to conduct its business in compliance with these requirements as applicable. Violations of these rules may result in criminal and civil fines and penalties.

Compliance Program

The Company maintains a global compliance program that includes ongoing evaluation and monitoring of its compliance with the laws and regulations of the U.S. and the other countries in which it has operations. The objective of the Company’s compliance program is to develop, implement, monitor, and update compliance safeguards, as appropriate. Although the Company is subject to a broad range of regulations, its compliance program has a particular focus on regulations related to healthcare fraud and abuse, anti-kickback, physician self-referral, government reimbursement programs, anti-bribery/anti-corruption, anti-human trafficking, and trade sanctions, among others. Emphasis is placed on developing and implementing compliance policies and guidelines, personnel training programs, monitoring and auditing activities, and providing systems for reporting and investigation of potential or actual compliance concerns. The compliance program demonstrates the Company's commitment to conducting business at the highest standards of ethical conduct and integrity.

The Company seeks to conduct its business in compliance with all statutes, regulations, and other requirements applicable to its clinical laboratory operations and drug development business. The clinical laboratory industry and drug development industries are, however, subject to extensive regulation, and many of these statutes and regulations have not been interpreted by the courts. In addition, the applicability or interpretation of statutes and regulations may not be clear in light of emerging changes in clinical testing science, healthcare technology, and healthcare organizations. Applicable statutes and regulations may be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would materially adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant civil and criminal penalties, fines, exclusion from participation in governmental healthcare programs, and the loss of various licenses, certificates, and authorizations necessary to operate, as well as potential liabilities from third-party claims, all of which could have a material adverse effect on the Company’s business.

Information Security

Information security is one of the Company's top priorities. Securing personal and health information is critical to the Company’s business operations and to future growth, as the Company is committed to using technology to improve the delivery of care. A security breach could have a material adverse operational, financial, regulatory, and reputational impact to the Company. The Company employs a secure technology framework that enables continuous operations of laboratory devices, computers, and communications systems. The Company has experienced and expects to continue to confront attempts by cybercriminals who seek access to its systems and data.

The Company uses state-of-the art tools and advanced analytics to proactively identify and protect against potential information system disruptions and breaches; to monitor, test and secure key networks and services, and to facilitate prompt resumption of operations if a system disruption or interruption should occur. The Company has implemented policies and procedures designed to comply with global laws and regulations related to the privacy and security of personal and health information. Additionally, the Company maintains a comprehensive behavior management and communications program, which addresses the human element of cybersecurity by providing staff with extensive awareness, education, and training to help prevent cybercrime from succeeding through human error.

The Company is exposed to risks related to information security arising from the information technology systems and operations of third parties, including the Company's vendors and partners. Therefore, the Company follows a process to evaluate the cybersecurity status of vendors or third parties that will have access to the Company's data or information technology systems. The Company also carries cybersecurity and business interruption insurance.

Over the past several years, the Company has significantly increased its investment in cybersecurity technology and training to help protect its information technology systems and operations in response to the ever-evolving cyber threat landscape. Additional resources will be dedicated as needed to expand the Company’s ability to investigate and remediate any cybersecurity vulnerabilities, and to manage any impact of a cybersecurity event on its business and operations.

In July 2018, the Company experienced a ransomware incident which affected certain Dx information technology systems. The incident temporarily affected certain other information technology systems involved in conducting Company-wide operations. An investigation determined that the ransomware did not and could not transfer patient or client data outside of Company systems and that there was no theft or misuse of patient or client data.

On May 14, 2019, Retrieval-Masters Credit Bureau, Inc. d/b/a/ American Medical Collections Agency (AMCA), an external collection agency, notified the Company about a security incident AMCA experienced that may have involved certain personal information about some of the Company's patients (the AMCA Incident). The Company is involved in pending and threatened litigation related to the AMCA Incident, as well as various government and regulatory inquiries and processes. For additional information about the AMCA Incident, see Note 14 Commitments and Contingencies to the Consolidated Financial Statements and “Risk Factors - Risks Related to Technology and Cybersecurity”.

Item 1A. Risk Factors

Investors should carefully consider all of the information set forth in this Annual Report, including the following risk factors, before deciding to invest in any of the Company’s securities. The risks below are not the only ones that the Company faces. Additional risks not presently known to the Company, or that it presently deems immaterial, may also negatively impact the Company. The Company’s business, consolidated financial condition, revenues, results of operations, profitability, reputation or cash flows could be materially impacted by any of these factors.

Risks Related to the Company's Business Including Global Economic and Sociopolitical Factors

General or macro-economic factors in the U.S. and globally may have a material adverse effect upon the Company, and significant fluctuations in the economy, recession, inflation and an increase in the costs of goods and services could negatively impact testing volumes, drug development services, cash collections, profitability and the availability and cost of credit.

The Company’s operations are dependent upon ongoing demand for diagnostic testing and drug development services by patients, physicians, hospitals, MCOs, pharmaceutical, biotechnology and medical device companies and others. Fluctuations in the global economy, including inflation and the risk of short- or long-term recession, inflation and an increase in the costs of goods and services have impacted and in the future could have continued or greater negative impact on the demand for diagnostic testing and drug development services, the ability of customers to pay for services rendered, and the Company’s profitability. In addition, uncertainty in the credit markets and fluctuations in interest rates could reduce the availability and increase the cost of credit and impact the Company’s ability to meet its financing needs in the future.

Index

Operations may be disrupted and adversely impacted by the effects of adverse weather, natural disasters, geopolitical events, public health crises, hostilities or acts of terrorism, acts of vandalism, disruption to supply chains, access to natural resources, and other events outside of the Company's control.

Natural disasters, such as adverse weather, fires, earthquakes, power shortages and outages, geopolitical events, such as terrorism, war, political instability, or other conflict, public health crises and disease epidemics and pandemics, criminal activities, disruptions to supply chains, access to natural resources, and other disruptions or events outside of the Company’s control could negatively affect the Company’s operations. Any of these events may result in a temporary decline of volumes in both segments. In addition, such events may temporarily interrupt the Company’s ability to transport specimens, efficiently commence studies, utilize information technology systems, utilize certain laboratories, and/or ability to receive material from its suppliers. Such events can also affect customer operations and thereby impact testing volume. Long-term disruptions in the infrastructure and operations caused by such events (particularly involving locations in which the Company has operations), could harm the Company's operating results.

An inability to attract and retain experienced and qualified personnel, including key management personnel, and increased personnel costs, could adversely affect the Company’s business.

The loss of key management personnel or the inability to attract and retain experienced and qualified employees, at the Company’s clinical laboratories, drug development, and diagnostic facilities, and increased costs related to such personnel and employees, could adversely affect the business. The success of the Company is dependent in part on the efforts of key members of its management team. Success in maintaining the Company’s leadership position in genomic and other advanced testing and diagnostic technologies will depend in part on the Company’s ability to attract and retain skilled research professionals. In addition, the success of the Company’s early discovery, clinical, and commercial laboratories also depend on employing and retaining qualified and experienced professionals, including specialists, who perform laboratory research activities and testing services. The same is true for patient-facing staff with specialized training required to perform activities related to specimen collection or clinical research activities. In the future, if competition for the services of these professionals increases, the Company may not be able to continue to attract and retain individuals in its markets. Changes in key management, or the ability to attract and retain qualified personnel, as a result of increased competition for talent, wage growth, or other market factors, could lead to strategic and operational challenges and uncertainties, distractions of management from other key initiatives, and inefficiencies and increased costs, any of which could adversely affect the Company’s business, financial condition, results of operations, and cash flows.

Continued changes in healthcare reimbursement models and products (e.g., health insurance exchanges), changes in government payment and reimbursement systems, or changes in payer mix, including an increase in third-party benefits management and value-based payment models, could have a material adverse effect on the Company's revenues, profitability and cash flow.

Dx's testing services are billed to MCOs, Medicare, Medicaid, physicians and physician groups, hospitals, patients and employer groups. Most testing services are billed to a party other than the physician or other authorized person who ordered the test. Increases in the percentage of services billed to government and MCOs could have an adverse effect on the Company’s revenues.

The Company serves many MCOs. These organizations have different contracting philosophies, which are influenced by the design of their products. Some MCOs contract with a limited number of clinical laboratories and engage in direct negotiation of rates. Other MCOs adopt broader networks with generally uniform fee structures for participating clinical laboratories. In some cases, those fee structures are specific to independent clinical laboratories, while the fees paid to hospital-based and physician-office laboratories may be different, and are typically higher. MCOs may also offer Managed Medicare or Managed Medicaid plans. In addition, an increasing number of MCOs are implementing, directly or through third parties, various types of laboratory benefit management programs that may include laboratory networks, utilization management tools (such as prior authorization and/or prior notification), and claims edits, which may impact coverage or reimbursement for commercial laboratory tests. Some of these programs address commercial laboratory testing broadly, while others are focused on certain types of testing such as molecular, genetic and toxicology testing. An increase in the use of such programs could lead to increased denial of claims, extended appeals, and reduced revenue.

Some MCOs use capitation rates to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement arrangement, the clinical laboratory receives a per-member, per-month payment for an agreed upon menu of laboratory tests provided to MCO members during the month, regardless of the number of tests performed. Capitation shifts the risk of increased test utilization (and the underlying mix of testing services) to the commercial laboratory provider. The

Index

Company makes significant efforts to obtain adequate compensation for its services in its capitated arrangements. For the year ended December 31, 2022, such capitated contracts accounted for approximately $332.3 million, or 3.2%, of Dx's revenues.

The Company's ability to attract and retain MCOs is critical given the impact of healthcare reform, related products and expanded coverage (e.g. health insurance exchanges and Medicaid expansion) and evolving value-based care and risk-based reimbursement delivery models (e.g., accountable care organizations (ACOs) and Independent Physician Associations (IPAs)).

A portion of the managed care fee-for-service revenues is collectible from patients in the form of deductibles, coinsurance and copayments. As patient cost-sharing has been increasing, the Company's collections may be adversely impacted.

In addition, Medicare and Medicaid and private insurers have increased their efforts to control the cost, utilization and delivery of healthcare services, including commercial laboratory services. Measures to regulate healthcare delivery in general, and clinical laboratories in particular, have resulted in reduced prices, added costs and decreased test utilization for the commercial laboratory industry by increasing complexity and adding new regulatory and administrative requirements. Pursuant to legislation passed in late 2003, the percentage of Medicare beneficiaries enrolled in Managed Medicare plans has increased. The percentage of Medicaid beneficiaries enrolled in Managed Medicaid plans has also increased; however, changes to, or repeal of, the Patient Protection and Affordable Care Act (ACA) may continue to affect coverage, reimbursement, and utilization of laboratory services, as well as administrative requirements, in ways that are currently unpredictable. Further healthcare reform could adversely affect laboratory reimbursement from Medicare, Medicaid or commercial carriers.

The Company has periodically experienced delays in the pricing and implementation of coding and billing changes among various payers, including Medicaid, Medicare and commercial carriers. While some delays were expected, payer policy changes in coverage have had a negative impact on revenue, revenue per requisition, and margins and cash flows. In 2022, limited coding and billing changes were implemented. While limited changes are expected to be implemented in 2023, the Company typically expects some delays in pricing and reimbursement as new codes are introduced.

The Company expects the efforts to impose reduced reimbursement, more stringent payment policies, and utilization and cost controls by government and other payers to continue. If Dx cannot offset additional reductions in the payments it receives for its services by reducing costs, increasing test volume, and/or introducing new services and procedures, it could have a material adverse effect on the Company’s revenues, profitability and cash flows. In 2014, Congress passed PAMA, requiring Medicare to change the way payment rates are calculated for tests paid under the CLFS, and to base the payment on the weighted median of rates paid by private payers. On June 23, 2016, CMS issued a final rule to implement PAMA that required applicable laboratories, including Dx, to begin reporting their test-specific private payer payment amounts to CMS during the first quarter of 2017. CMS exercised enforcement discretion to permit reporting for an additional 60 days, through May 30, 2017. CMS used that private market data to calculate weighted median prices for each test (based on applicable current procedural technology (CPT) codes) to represent the new CLFS rates beginning in 2018, subject to certain phase-in limits. For 2018-2020, a test price could not be reduced by more than 10% per year. As a result of provisions included within the CARES Act, PAMA rate reductions for 2021 were suspended, and therefore the Company did not experience any incremental reimbursement rate impact due to PAMA in 2021. As a result of the Protecting Medicare and American Farmers from Sequester Cuts Act that became law in December 2021, the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2022 were delayed by one additional year, and the Company did not experience incremental reimbursement rate impact due to PAMA in 2022. As a result of the Consolidated Appropriations Act, 2023, which became law in December 2022, the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2023 were delayed by one additional year, and the Company will not experience an incremental reimbursement rate impact due to PAMA in 2023.

For 2024-2026, a test price cannot be reduced by more than 15.0% per year. The process of data reporting and repricing will be repeated every three years for Clinical Diagnostic Laboratory Tests (CDLTs) beginning in 2024. CFLS rates for 2027 and subsequent periods will not be subject to phase-in limits. The phase-in of rates for CDLTs established in 2018 will resume in 2024. New CLFS rates will be established in 2025 based on data from 2019 to be reported in 2024. New CLFS rates will be established in 2028 based on data from 2026 to be reported in 2027 CLFS rates for Advanced Diagnostic Laboratory Tests (ADLTs) will be updated annually.

CMS published its initial proposed CLFS rates under PAMA for 2018-2020 on September 22, 2017. Following a public comment period, CMS made adjustments and published final CLFS rates for 2018-2020 on November 17, 2017, with additional adjustments published on December 1, 2017. For 2020, the Company realized a net reduction in reimbursement of approximately $72.01 million from all payers affected by the CLFS (approximately $107.0 million in 2019). 2021, 2022 and 2023 PAMA rates were frozen as described above. Unless implementation of PAMA is further delayed or changed, an additional reduction of approximately $100.0 million is expected for 2024, from all payers affected by the CLFS.

Index

Healthcare reform legislation also contains numerous regulations that will require the Company, as an employer, to implement significant process and record-keeping changes to be in compliance. These changes increase the cost of providing healthcare coverage to employees and their families. Given the limited release of regulations to guide compliance, as well as potential changes to the ACA, the exact impact to employers, including the Company, is uncertain.

Changes in government regulation or in practices relating to the pharmaceutical, biotechnology, or medical device industries could decrease the need for certain services that DD provides.

DD assists pharmaceutical, biotechnology and medical device companies in navigating the regulatory approval process. Changes in regulations such as a relaxation in regulatory requirements or the introduction of simplified approval procedures, or an increase in regulatory requirements that DD has difficulty satisfying or that make its services less competitive, could eliminate or substantially reduce the demand for its services. Also, if government efforts to contain drug and medical product and device costs impact profits from such items, or if health insurers were to change their practices with respect to reimbursement for those items, some of DD’s customers may spend less, or reduce their growth in spending on R&D.

In addition, implementation of healthcare reform legislation that adds costs could limit the profits that can be made from the development of new drugs and medical products and devices. This could adversely affect R&D expenditures by such companies, which could in turn decrease the business opportunities available to DD both in the U.S. and other countries. New laws or regulations may create a risk of liability, increase DD costs or limit service offerings through DD.

Increased competition, including price competition, could have an adverse effect on the Company’s revenues and profitability.

As further described in Item 1 of Part I of this Annual Report, both Dx and DD operate in highly competitive industries. The commercial laboratory business is intensely competitive both in terms of price and service. Pricing of laboratory testing services is often one of the most significant factors used by physicians, third-party payers and consumers in selecting a laboratory. As a result of significant consolidation in the commercial laboratory industry, larger commercial laboratory providers are able to increase cost efficiencies afforded by large-scale automated testing. This consolidation results in greater price competition. Dx may be unable to increase cost efficiencies sufficiently, if at all, and as a result, its net earnings and cash flows could be negatively impacted by such price competition. The Company may face increased competition from health system laboratories, due to physicians within those systems directing their testing to the health system laboratory and away from the Company, and as those laboratories seek to expand their testing volume from unaffiliated physicians in their service areas. The Company may also face competition from companies that do not comply with existing laws or regulations or otherwise disregard compliance standards in the industry. Additionally, the Company may also face changes in fee schedules, competitive bidding for laboratory services, or other actions or pressures reducing payment schedules as a result of increased or additional competition.

Competitors in the CRO industry range from hundreds of smaller CROs to a limited number of large CROs with global capabilities. DD’s main competition consists of these small and large CROs, as well as in-house departments of pharmaceutical, biotechnology and medical device companies and, to a lesser extent, select universities and teaching hospitals. DD’s services have from time to time experienced periods of increased price competition that had an adverse effect on a segment's profitability and consolidated revenues and net income. There is competition among CROs for both customers and potential acquisition candidates. Additionally, few barriers to entering the CRO industry further increases possible new competition.

These competitive pressures may affect the attractiveness or profitability of Dx’s and DD’s services, and could adversely affect the financial results of the Company.

Failure to obtain and retain new customers, the loss of existing customers or material contracts, or a reduction in services or tests ordered or specimens submitted by existing customers, or the inability to retain existing and/or create new relationships with health systems could impact the Company’s ability to successfully grow its business.

To maintain and grow its business, the Company needs to obtain and retain new customers and business partners. In addition, a reduction in tests ordered or specimens submitted by existing customers, a decrease in demand for the Company's services from existing customers, or the loss of existing contracts, without offsetting growth in its customer base, could impact the Company's ability to successfully grow its business and could have a material adverse effect on the Company’s revenues and profitability. The Company competes primarily on the basis of the quality of services, reporting and information systems, reputation in the medical community and the drug development industry, the pricing of services and ability to employ qualified personnel. The Company's failure to successfully compete on any of these factors could result in the loss of existing customers, an inability to gain new customers and a reduction in the Company's business.

Discontinuation or recalls of existing testing products; failure to develop or acquire licenses for new or improved testing technologies; or the Company’s customers using new technologies to perform their own tests could adversely affect the Company’s business.

Index

From time to time, manufacturers discontinue or recall reagents, test kits or instruments used by the Company to perform laboratory testing. Such discontinuations or recalls could adversely affect the Company’s costs, testing volume and revenue.

The commercial laboratory industry is subject to changing technology and new product introductions. The Company’s success in maintaining a leadership position in genomic and other advanced testing technologies will depend, in part, on its ability to develop, acquire or license new and improved technologies on favorable terms and to obtain appropriate coverage and reimbursement for these technologies. The Company may not be able to negotiate acceptable licensing arrangements, and it cannot be certain that such arrangements will yield commercially successful diagnostic tests. If the Company is unable to license these testing methods at competitive rates, its research and development (R&D) costs may increase as a result. In addition, if the Company is unable to license new or improved technologies to expand its esoteric testing operations, its testing methods may become outdated when compared with the Company’s competition, and testing volume and revenue may be materially and adversely affected.

In addition, advances in technology may lead to the development of more cost-effective technologies such as point-of-care testing equipment that can be operated by physicians or other healthcare providers (including physician assistants, nurse practitioners and certified nurse midwives, generally referred to herein as physicians) in their offices or by patients themselves without requiring the services of freestanding clinical laboratories. Development of such technology and its use by the Company’s customers could reduce the demand for its laboratory testing services and the utilization of certain tests offered by the Company and negatively impact its revenues.

Currently, most commercial laboratory testing is categorized as high or moderate complexity, and thereby is subject to extensive and costly regulation under CLIA. The cost of compliance with CLIA makes it impractical for most physicians to operate clinical laboratories in their offices, and other laws limit the ability of physicians to have ownership in a laboratory and to refer tests to such a laboratory. Manufacturers of laboratory equipment and test kits could seek to increase their sales by marketing point-of-care laboratory equipment to physicians and by selling test kits approved for home or physician office use to both physicians and patients. Diagnostic tests approved for home use are automatically deemed to be “waived” tests under CLIA and may be performed in physician office laboratories as well as by patients in their homes with minimal regulatory oversight. Other tests meeting certain FDA criteria also may be classified as “waived” for CLIA purposes. The FDA has regulatory responsibility over instruments, test kits, reagents and other devices used by clinical laboratories, and it has taken responsibility from the U.S. Centers for Disease Control and Prevention for classifying the complexity of tests for CLIA purposes. Increased approval of “waived” test kits could lead to increased testing by physicians in their offices or by patients at home, which could affect the Company’s market for laboratory testing services and negatively impact its revenues.

Changes or disruption in services supplies, or transportation provided by third parties have impacted and could continue to impact or adversely affect the Company’s business.

The Company depends on third parties to provide supplies and services critical to the Company’s business. Although the Company has a significant proprietary network of ground and air transport capabilities, certain of the Company's businesses are heavily reliant on third-party ground and air travel for transport of clinical trial and diagnostic testing supplies and specimens, research products, and people. A significant disruption to these travel systems, or the Company's access to them, could have a material adverse effect on the Company's business. The Company is also reliant on an extensive network of third-party suppliers and vendors of certain services and products, including for certain animal populations. Disruptions to the continued supply, or increases in costs, of these services, products, or animal populations may arise from export/import restrictions or embargoes, political or economic instability, pressure from animal rights activists, adverse weather, natural disasters, public health crises, transportation disruptions, cyber attacks, or other causes, as well as from termination of relationships with suppliers or vendors for their failure to follow the Company’s performance standards and requirements. Disruption of supply and services has impacted and could continue to impact or have a material adverse effect on the Company’s business.

A failure to identify and successfully close and integrate strategic acquisition targets could have a material adverse effect on the Company's business objectives and its revenues and profitability.

Part of the Company's strategy involves deploying capital in investments that enhance the Company's business, which includes pursuing strategic acquisitions to strengthen the Company's scientific capabilities and enhance therapeutic expertise, enhance esoteric testing and global drug development capabilities, and increase presence in key geographic areas. Since 2018, the Company has invested net cash of approximately $2.9 billion in strategic business acquisitions. However, the Company cannot assure that it will be able to identify acquisition targets that are attractive to the Company or that are of a large enough size to have a meaningful impact on the Company's operating results. Furthermore, the successful closing and integration of a strategic acquisition entails numerous risks, including, among others:

•failure to obtain regulatory clearance, including due to antitrust concerns;

•loss of key customers or employees;

Index

•difficulty in consolidating redundant facilities and infrastructure and in standardizing information and other systems;

•unidentified regulatory problems;

•failure to maintain the quality of services that such companies have historically provided;

•unanticipated costs and other liabilities;

•potential liabilities related to litigation including the acquired companies;

•potential periodic impairment of goodwill and intangible assets acquired;

•coordination of geographically separated facilities and workforces; and

•the potential disruption of the ongoing business and diversion of management's resources.

The Company cannot assure that current or future acquisitions, if any, or any related integration efforts will be successful, or that the Company's business will not be adversely affected by any future acquisitions, including with respect to revenues and profitability. Even if the Company is able to successfully integrate the operations of businesses that it may acquire in the future, the Company may not be able to realize the benefits that it expects from such acquisitions.

Unfavorable labor environments, union strikes, work stoppages, union or works council negotiations, or failure to comply with labor or employment laws could adversely affect the Company's operations and have a material adverse effect upon the Company's business.

The Company is a party to a limited number of collective bargaining agreements with various labor unions and is subject to employment and labor laws and unionization activity in the U.S. Similar employment and labor obligations exist across other countries in which it conducts business, including appropriate engagement with works councils in Europe. Disputes with regard to the terms of labor agreements or obligations for consultation, potential inability to negotiate acceptable contracts with these unions, unionization activity, or a failure to comply with labor or employment laws could result in, among other things, labor unrest, strikes, work stoppages, slowdowns by the affected workers, fines and penalties. If any of these events were to occur, or other employees were to become unionized, the Company could experience a significant disruption of its operations or higher ongoing labor costs, either of which could have a material adverse effect upon the Company's business. Additionally, future labor agreements, or renegotiation of labor agreements or provisions of labor agreements, or changes in labor or employment laws, could compromise its service reliability and significantly increase its costs, which could have a material adverse effect upon the Company's business. Also, the Company may incur substantial additional costs and become subject to litigation and enforcement actions if the Company fails to comply with legal requirements affecting its workforce and labor practices, including laws and regulations related to wage and hour practices, Office of Federal Contract Compliance Programs (OFCCP) compliance, and unlawful workplace harassment and discrimination.

Continued and increased consolidation of pharmaceutical, biotechnology and medical device companies, health systems, physicians and other customers could adversely affect the Company's business.

Many healthcare companies and providers, including pharmaceutical, biotechnology and medical device companies, health systems and physician practices are consolidating through mergers, acquisitions, joint ventures and other types of transactions and collaborations. In addition to these more traditional horizontal mergers that involve entities that previously competed against each other, the healthcare industry is experiencing an increase in vertical mergers, which involve entities that previously did not offer competing goods or services. As the healthcare industry consolidates, competition to provide goods and services may become more intense, and vertical mergers may give those combined companies greater control over more aspects of healthcare, including increased bargaining power. This competition and increased customer bargaining power may adversely affect the price and volume of the Company’s services.

In addition, as the broader healthcare industry trend of consolidation continues, including the acquisition of physician practices by health systems, relationships with hospital-based health systems and integrated delivery networks are becoming more important. Dx has a well-established base of relationships with those systems and networks, including collaborative agreements. Dx's inability to retain its existing relationships with those physicians as they become part of healthcare systems and networks and/or to create new relationships could impact its ability to successfully grow its business.

Damage or disruption to the Company’s facilities could adversely affect the Company’s business.

Many of the Company’s facilities could be difficult to replace in a short period of time. Any event that causes a disruption of the operation of these facilities might impact the Company's ability to provide services to customers and, therefore, could have a material adverse effect on the Company's financial condition, results of operations, and cash flows.

Risks Related to Financial Matters

The Company bears financial risk for contracts that, including for reasons beyond the Company's control, may be underpriced, subject to cost overruns, delayed, or terminated or reduced in scope.

The Company has many contracts that are structured as fixed-price for fixed-contracted services or fee-for-service with a

Index

cap. The Company bears the financial risk if these contracts are underpriced or if contract costs exceed estimates. Such underpricing or significant cost overruns could have an adverse effect on the Company's business, results of operations, financial condition and cash flows.

Many of DD’s contracts, in particular, provide for services on a fixed-price or fee-for-service with a cap basis and they may be terminated or reduced in scope either immediately or upon notice. Cancellations may occur for a variety of reasons, including:

•failure of products to satisfy safety requirements;

•unexpected or undesired results of the products;

•insufficient clinical trial subject enrollment;

•insufficient investigator recruitment;

•a customer's decision to terminate the development of a product or to end a particular study; and

•DD’s failure to perform its duties properly under the contract.

Although its contracts often entitle it to receive the costs of winding down the terminated projects, as well as all fees earned up to the time of termination, the loss, reduction in scope or delay of a large contract or the loss, delay or conclusion of multiple contracts could materially adversely affect DD.

A significant increase in the Company's days sales outstanding could have an adverse effect on the Company’s business, including its cash flow, by increasing its bad debt or decreasing its cash flow.

Billing for laboratory services is a complex process. Laboratories bill many different payers, including doctors, patients, hundreds of insurance companies, Medicare, Medicaid and employer groups, all of which have different billing requirements. In addition to billing complexities, Dx has experienced an increase in patient responsibility as a result of managed care fee-for-service plans that continue to increase patient deductibles, coinsurance and copayments, or implement restrictive coverage or administrative policies that can further increase patient costs. Dx expects this trend to continue. A material increase in Dx’s days sales outstanding level could have an adverse effect on the Company's business, including potentially increasing its bad debt rate and decreasing its cash flows. Although DD does not face the same level of complexity in its billing processes, it could also experience delays in billing or collection, and a material increase in DD’s days sales outstanding could have an adverse effect on the Company’s business, including potentially decreasing its cash flows.

DD’s revenues depend on the pharmaceutical, biotechnology and medical device industries.

DD’s revenues depend greatly on the expenditures made by the pharmaceutical, biotechnology and medical device industries in R&D. In some instances, these companies are reliant on their ability to raise capital in order to fund their R&D projects. These companies are also reliant on reimbursement for their products from government programs and commercial payers. Accordingly, economic factors and industry trends affecting DD’s customers in these industries may also affect DD. If these companies were to reduce the number of R&D projects they conduct or outsource, whether through the inability to raise capital, reductions in reimbursement from governmental programs or commercial payers, industry trends, economic conditions or otherwise, DD could be materially adversely affected.

Foreign currency exchange fluctuations could have an adverse effect on the Company’s business.

The Company has business and operations outside the U.S., and DD derives a significant portion of its revenues from international operations. Since the Company's consolidated financial statements are denominated in U.S. dollars, fluctuations in exchange rates from period to period will have an impact on reported results. In addition, DD may incur costs in one currency related to its services or products for which it is paid in a different currency. As a result, factors associated with international operations, including changes in foreign currency exchange rates, could significantly affect DD's results of operations, financial condition and cash flows.

The Company’s uses of financial instruments to limit its exposure to interest rate and currency exchange fluctuations could expose it to risks and financial losses that may adversely affect the Company’s financial condition, liquidity and results of operations.

To limit the Company’s exposure to interest rate fluctuations and currency exchange fluctuations, it has entered into, and in the future may enter into for these or other purposes, financial swaps, or hedging arrangements, with various financial counterparties. In addition to any risks related to the counterparties, there can be no assurances that the Company’s hedging activity will be effective in insulating it from the risks associated with the underlying transactions, that the Company would not have been better off without entering into these hedges, or that the Company will not have to pay additional amounts upon settlement.

Index

The Company’s level of indebtedness and debt service requirements could adversely affect the Company’s liquidity, results of operations and business.

At December 31, 2022, indebtedness on the Company's outstanding Senior Notes totaled approximately $5,450.0 million in aggregate principal. The Company is also a party to credit agreements relating to a $1.0 billion revolving credit facility. Under the revolving credit facility, the Company is subject to negative covenants limiting subsidiary indebtedness and certain other covenants typical for investment-grade-rated borrowers, and the Company is required to maintain a leverage ratio within certain limits.

The Company’s level of indebtedness and debt service requirements could adversely affect its business. In particular, it could increase the Company’s vulnerability to sustained, adverse macroeconomic weakness, limit its ability to obtain further financing or refinance existing debt at maturity, and limit its ability to pursue certain operational and strategic opportunities, including large acquisitions. Additionally, the Company's cost of funds could increase due to the impact of increases in prevailing interest rates on its variable rate debt and should the Company refinance existing debt at maturity or obtain further financing.

The Company may also enter into additional transactions or credit facilities, including other long-term debt, which may increase its indebtedness and result in additional restrictions upon the business. In addition, major debt rating agencies regularly evaluate the Company's debt based on a number of factors. There can be no assurance that the Company will be able to maintain its existing debt ratings, and failure to do so could adversely affect the Company's cost of funds, liquidity and access to capital markets.

The Company's quarterly operating results may vary.

The Company's operating results may vary significantly from quarter to quarter and are influenced by factors over which the Company has little control, such as:

•changes in the general global economy;

•exchange rate fluctuations;

•the commencement, completion, delay or cancellation of large projects or contracts or groups of projects;

•the progress of ongoing projects;

•weather;

•the timing of and charges associated with completed acquisitions or other events; and

•changes in the utilization mix of the Company's services.

The Company believes that operating results for any particular quarter are not necessarily a meaningful indication of future results. While fluctuations in the Company's quarterly operating results could negatively or positively affect the market price of the Company's common stock, these fluctuations may not be related to the Company's future overall operating performance.

Risks Related to the Planned Spin-off of the Company’s Clinical Development and Commercialization Services Business

The planned spin-off of the Company’s Clinical Development and Commercialization Services business may not be completed on the terms or timeline currently contemplated, if at all, and may not achieve the intended results.

The Company is pursuing a spin-off of its wholly owned Clinical Development and Commercialization Services (CDCS) business, which includes the parts of its DD segment focused on providing Phase I-IV clinical trial management, market access, and technology solutions to pharmaceutical and biotechnology organizations, which would result in two independent, publicly traded companies. Unanticipated issues including, but not limited to, the failure to obtain regulatory approval, obtain appropriate assurances regarding the tax-free nature of the spin-off, or have the Form 10 registration statement that will be filed with the SEC declared effective on a timely basis or at all, could delay, prevent, or otherwise adversely affect the planned spin-off. There can be no assurance that the conditions of the spin-off will be satisfied or that Company will be able to complete the spin-off on the terms or on the anticipated timeline, or at all.

The Company expects that pursuing and implementing the spin-off will continue to require significant expenses and management time and effort, may divert management’s attention from the Company and CDCS' ongoing business operations and may adversely impact relationships with customers, suppliers, employees, and other business counterparties. The Company may experience delays, business disruption, increased costs, including from lost synergies or from restructuring transactions, negative market reaction to the announcement and planning for the transaction, change in market receptiveness to effect transactions in the capital markets, and other challenges during or following the spin-off, which could adversely affect the Company’s business, financial condition, and results of operations. The Company may also experience increased challenges in attracting, retaining, and motivating key personnel during the pendency of the spin-off and following its completion, which could harm the Company’s business. The Company anticipates that, consistent with any applicable legal and tax requirements, there will be ongoing transitional and commercial arrangements to provide for a seamless delivery of services to the customers

Index

and other stakeholders of the independent companies following the spin-off, but those arrangements may not meet the intended objectives, which could negatively impact the Company’s and CDCS’ business, including relationships with customers and other business counterparties.

Further, if the planned spin-off is completed, the anticipated benefits of the transaction may not be realized within the expected time periods or at all. Failure to implement the planned spin-off effectively or the negative reaction of customers, the Company’s employees, and other stakeholders could also result in a decline in value of one or both of the companies.

Risks Related to Regulatory and Compliance Matters

Changes, including changes in interpretation, in payer regulations, policies or approvals, or changes in laws, regulations or policies in the U.S. or globally, may adversely affect the Company.

U.S. and state government payers, such as Medicare and Medicaid, as well as insurers, including MCOs, have increased their efforts to control the cost, utilization and delivery of healthcare services. From time to time, Congress has considered and implemented changes in Medicare fee schedules in conjunction with budgetary legislation. The first phase of reductions pursuant to PAMA came into effect on January 1, 2018, and will continue annually subject to certain delays in implementation and phase-in limits through 2026, and without limitations for subsequent periods. Further reductions due to changes in policy regarding coverage of tests or other requirements for payment, such as prior authorization, diagnosis code and other claims edits, may be implemented from time to time. Reimbursement for pathology services performed by Dx is also subject to statutory and regulatory reduction. Reductions in the reimbursement rates and changes in payment policies of other third-party payers may occur as well. Such changes in the past have resulted in reduced payments as well as added costs and have decreased test utilization for the commercial laboratory industry by adding more complex new regulatory and administrative requirements. Further changes in third-party payer regulations, policies, or laboratory benefit or utilization management programs may have a material adverse effect on Dx's business. Actions by federal and state agencies regulating insurance, including healthcare exchanges, or changes in other laws, regulations, or policies may also have a material adverse effect upon Dx's business.

The Company could face significant monetary damages and penalties and/or exclusion from government programs if it violates anti-fraud and abuse laws.

The Company is subject to extensive government regulation at the federal, state, and local levels in the U.S. and other countries where it operates. The Company’s failure to meet governmental requirements under these regulations, including those relating to billing practices and financial relationships with physicians, hospitals, and health systems could lead to civil and criminal penalties, exclusion from participation in Medicare and Medicaid and possible prohibitions or restrictions on the use of its laboratories. While the Company believes that it is in material compliance with all statutory and regulatory requirements, there is a risk that government authorities might take a contrary position. This risk includes, but is not limited to, the potential that government enforcement authorities may take a contrary position with respect to the Eliminating Kickbacks in Recovery Act, given the lack of associated regulations to clarify or add exceptions. Such occurrences, regardless of their outcome, could damage the Company’s reputation and adversely affect important business relationships.

The Company’s business could be harmed from the loss or suspension of a license or imposition of a fine or penalties under, or future changes in, or interpretations of, the law or regulations of CLIA, Medicare, Medicaid or other national, state or local agencies in the U.S. and other countries where the Company operates laboratories.

The commercial laboratory testing industry is subject to extensive U.S. regulation, and many of these statutes and regulations have not been interpreted by the courts. CLIA extends federal oversight to virtually all clinical laboratories operating in the U.S. by requiring that they be certified by the federal government or by a federally approved accreditation agency. The sanction for failure to comply with CLIA requirements may be suspension, revocation or limitation of a laboratory’s CLIA certificate, which is necessary to conduct business, as well as significant fines and/or criminal penalties. In addition, the Company is subject to regulation under state law. State laws may require that laboratories and/or laboratory personnel meet certain qualifications, specify certain quality controls or require maintenance of certain records. The Company also operates laboratories outside of the U.S. and is subject to laws governing its laboratory operations in the other countries where it operates.

Applicable statutes and regulations could be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would adversely affect the Company's business. Potential sanctions for violation of these statutes and regulations include significant fines and the suspension or loss of various licenses, certificates and authorizations, which could have a material adverse effect on the Company’s business. In addition, compliance with future legislation could impose additional requirements on the Company, which may be costly.

Failure of the Company or its third-party service providers to comply with privacy and security laws and regulations could result in fines, penalties and damage to the Company’s reputation with customers and have a material adverse effect upon the Company’s business.

If the Company and its third-party service providers do not comply with existing or new laws and regulations related to protecting the privacy and security of personal or health information, it could be subject to monetary fines, civil penalties or criminal sanctions.

In the U.S., the Health Insurance Portability and Accountability Act of 1996 (HIPAA) privacy and security regulations, including the expanded requirements under U.S. Health Information Technology for Economic and Clinical Health Act (HITECH), establish comprehensive standards with respect to the use and disclosure of protected health information (PHI), by covered entities, in addition to setting standards to protect the confidentiality, integrity and security of PHI.

HIPAA restricts the Company’s ability to use or disclose PHI, without patient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policy purposes and other permitted purposes outlined in the privacy regulations. HIPAA and HITECH provide for significant fines and other penalties for wrongful use or disclosure of PHI in violation of the privacy and security regulations, including potential civil and criminal fines and penalties. The regulations establish a complex regulatory framework on a variety of subjects, including:

•the circumstances under which the use and disclosure of PHI are permitted or required without a specific authorization by the patient, including, but not limited to, treatment purposes, activities to obtain payments for the Company’s services, and its healthcare operations activities;

•a patient’s rights to access, amend and receive an accounting of certain disclosures of PHI;

•the content of notices of privacy practices for PHI;

•administrative, technical and physical safeguards required of entities that use or receive PHI; and

•the protection of computing systems maintaining electronic PHI.

The Company has implemented policies and procedures designed to comply with the HIPAA privacy and security requirements as applicable. The privacy and security regulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, the Company is required to comply with both additional federal privacy and security regulations and varying state privacy and security laws. In addition, federal and state laws that protect the privacy and security of patient information may be subject to enforcement and interpretations by various governmental authorities and courts, resulting in complex compliance issues. For example, the Company could incur damages under state laws, including pursuant to an action brought by a private party for the wrongful use or disclosure of health information or other personal information.

The Company may also be required to comply with the data privacy and security laws of other countries in which it operates or with which it transfers and receives data. For example, the EU's General Data Protection Regulation (GDPR), which took effect May 25, 2018, created a range of compliance obligations for subject companies and imposes penalties for noncompliance of up to the greater of €20 million or 4% of worldwide revenue. The Company has established processes and frameworks to manage compliance with the GDPR. Potential fines and penalties in the event of a violation of the GDPR could have a material adverse effect on the Company’s business and operations. In addition, similar data protection regulations addressing access, use, disclosure and transfer of personal data have been enacted or updated in regions where the Company does business, including in Asia, Latin America, and Europe. The Company expects to make changes to its business practices and to incur additional costs associated with compliance with these evolving and complex regulations.

The Company's international operations could subject it to additional risks and expenses that could adversely impact the business or results of operations.

The Company's international operations expose it to risks from potential failure to comply with foreign laws and regulations that differ from those under which the Company operates in the U.S. In addition, the Company may be adversely affected by other risks of expanded operations in foreign countries, including, but not limited to, changes in reimbursement by foreign governments for services provided by the Company; compliance with export controls and trade regulations; changes in tax policies or other foreign laws; compliance with foreign labor and employee relations laws and regulations; restrictions on currency repatriation; judicial systems that less strictly enforce contractual rights; countries that do not have clear or well-established laws and regulations concerning issues relating to commercial laboratory testing or drug development services; countries that provide less protection for intellectual property rights; and procedures and actions affecting approval, production, pricing, reimbursement and marketing of products and services. Further, international operations could subject the Company to additional expenses that the Company may not fully anticipate, including those related to enhanced time and resources necessary to comply with foreign laws and regulations, difficulty in collecting accounts receivable and longer collection periods, and difficulties and costs of staffing and managing foreign operations. In some countries, the Company's success will depend in part on its ability to form relationships with local partners. The Company's inability to identify appropriate partners or

Index

reach mutually satisfactory arrangements could adversely affect the business and operations.

Expanded international operations may increase the Company’s exposure to liabilities under the anti-corruption laws.

Anti-corruption laws in the countries where the Company conducts business, including the U.S. Foreign Corrupt Practices Act (FCPA), U.K. Bribery Act, and similar laws in other jurisdictions, prohibit companies and their intermediaries from engaging in bribery including improperly offering, promising, paying or authorizing the giving of anything of value to individuals or entities for the purpose of corruptly obtaining or retaining business. The Company operates in some parts of the world where corruption may be common and where anti-corruption laws may conflict to some degree with local customs and practices. The Company maintains an anti-corruption program including policies, procedures, training and safeguards in the engagement and management of third parties acting on the Company’s behalf. Despite these safeguards, the Company cannot guarantee protection from corrupt acts committed by employees or third parties associated with the Company. Violations or allegations of violations of anti-corruption laws could have a significant adverse effect on the business or results of operations.

Failure to comply with the regulations of pharmaceutical and medical device regulatory agencies, such as the FDA, the Medicines and Healthcare Products Regulatory Agency in the United Kingdom (U.K.), the European Medicines Agency, the National Medical Products Administration in China (NMPA), and the Pharmaceuticals and Medical Devices Agency in Japan, could result in fines, penalties, and sanctions against DD and have a material adverse effect upon the Company.

The operation of DD's preclinical laboratory facilities and clinical trial operations must conform to good laboratory practice (GLP) and good clinical practice (GCP), as applicable, as well as all other applicable standards and regulations, as further described in Item 1 of Part I of this Annual Report. The business operations of DD’s clinical and preclinical laboratories also require the import, export and use of medical devices, in vitro diagnostic devices, reagents, and human and animal biological products. Such activities are subject to numerous applicable local and international regulations with which DD must comply. If DD does not comply, DD could potentially be subject to civil, criminal or administrative sanctions and/or remedies, including suspension of its ability to conduct preclinical and clinical studies, and to import or export to or from certain countries, which could have a material adverse effect upon the Company.

Additionally, certain DD services and activities must conform to current good manufacturing practice (cGMP), as further described in Item 1 of Part I of this Annual Report. Failure to maintain compliance with GLP, GCP, or cGMP regulations and other applicable requirements of various regulatory agencies could result in warning or untitled letters, fines, unanticipated compliance expenditures, suspension of manufacturing, and civil, criminal or administrative sanctions and/or remedies against DD, including suspension of its laboratory operations, which could have a material adverse effect upon the Company.

Increased regulations and restrictions on the import of research animals, limitations of supply of research animals, and actions of animal rights activists may have an adverse effect on the Company.

DD's preclinical services utilize animals in preclinical testing of the safety and efficacy of drugs and devices. Such activities are required for the development of new medicines and medical devices under regulatory regimes in the U.S., Europe, Japan, and other countries. Increased regulations and restrictions on the import of research animals into various countries, as well as limitations of supply, such as those the Company and others experienced in 2022 due to market factors in certain global regions, could impact DD’s ability to conduct preclinical research and could have an adverse effect on DD’s financial condition, results of operations, and cash flows. In addition, acts of vandalism and other acts by animal rights activists who object to the use of animals in drug development could have an adverse effect on the Company.

Animal populations may suffer diseases that can damage DD's inventory, harm its reputation, or result in other liability.

It is important that research products be free of diseases, including infectious diseases. The presence of diseases can distort or compromise the quality of research results, cause loss of animals in DD’s inventory, result in harm to humans or outside animal populations if the disease is not contained to animals in inventory, or result in other losses. Such results could harm DD’s reputation or have an adverse effect on DD's financial condition, results of operations, and cash flows.

Failure to conduct animal research in compliance with animal welfare laws and regulations could result in sanctions and/or remedies against DD and have a material adverse effect upon the Company.

The conduct of animal research at DD’s facilities must be in compliance with applicable laws and regulations in the jurisdictions in which those activities are conducted. These laws and regulations include the U.S. Animal Welfare Act (AWA), which governs the care and use of warm-blooded animals for research in the U.S. other than laboratory rats, mice and chickens, and is enforced through periodic inspections by the U.S. Department of Agriculture (USDA). The AWA establishes facility standards regarding several aspects of animal welfare, including housing, ventilation, lighting, feeding and watering, handling, veterinary care, and recordkeeping. Similar laws and regulations apply in other jurisdictions in which DD conducts animal research, including the UK, EU, and China. DD complies with licensing and registration requirement standards set by these

Index

laws and regulations in the jurisdictions in which it conducts animal research. If an enforcement agency determines that DD’s equipment, facilities, laboratories or processes do not comply with applicable standards, it may issue an inspection report documenting the deficiencies and setting deadlines for any required corrective actions. For noncompliance, the agency may take action against DD that may include fines, suspension and/or revocation of animal research licenses, or confiscation of research animals.

U.S. Food and Drug Administration (FDA) regulation of diagnostic products, increased FDA regulation of laboratory-developed tests (LDTs), and regulation by other countries of diagnostic products could result in increased costs and the imposition of fines or penalties, and could have a material adverse effect upon the Company’s business.

The FDA has regulatory responsibility for instruments, test kits, reagents and other devices used by clinical laboratories. The FDA enforces laws and regulations that govern the development, testing, manufacturing, performance, labeling, advertising, marketing, distribution, and surveillance of diagnostic products, and it regularly inspects and reviews the manufacturing processes and product performance of diagnostic products. Dx’s point-of-care testing devices are subject to regulation by the FDA.

Since the 1990s, the FDA has asserted that it has authority to regulate LDTs as medical devices, but has exercised enforcement discretion to refrain from systematic regulation of LDTs. In 2014, the FDA issued draft guidance describing how it intended to discontinue its enforcement discretion policy and begin regulating LDTs as medical devices; however, that draft guidance has not been finalized, and the FDA has instead continued its enforcement discretion policy and has indicated that it intends to work with Congress to enact comprehensive legislative reform of diagnostics oversight. As such, LDTs developed by high complexity clinical laboratories are currently generally offered as services to health care providers under the CLIA regulatory framework administered by CMS, without the requirement for FDA clearance or approval. There are other regulatory and legislative proposals that would increase general FDA oversight of clinical laboratories and LDTs. The outcome and ultimate impact of such proposals on the business is difficult to predict at this time. On February 20, 2020, the FDA issued a statement with a table of pharmacogenetic associations setting forth certain gene-drug interactions that the agency has determined are supported by the scientific literature to help ensure that claims being made for pharmacogenetic tests are grounded in sound science, thereby reducing the risk of enforcement actions with respect to LDTs offering claims consistent with the table. The FDA noted that while it is committed to work with Congress on new comprehensive diagnostic oversight reform legislation, it could still take enforcement actions under the current medical device framework regarding diagnostic claims the agency determines not to be sufficiently supported. Even without issuance of a finalized LDT oversight framework, in light of the April 4, 2019, FDA warning letter issued to Inova Genomics Laboratory related to certain LDTs that Inova offered, as well as the February 2020 pharmacogenetics statement and the failure to pass diagnostic reform legislation in 2022, there may be an increased risk of FDA enforcement actions for laboratory tests offered by companies without FDA clearance or approval.

Current FDA regulation of the Company’s diagnostic products and the potential for future increased regulation of the Company’s LDTs in the future could result in increased costs and administrative and legal actions for noncompliance, including warning letters, fines, penalties, product suspensions, product recalls, injunctions, and other civil and criminal sanctions, which could have a material adverse effect upon the Company.

Regulation of diagnostics products in jurisdictions outside the U.S. in which the Company operates may impact laboratory testing offered by the Company in both Dx and DD. For example, the European Union In Vitro Diagnostics Regulation (Regulation (EU) 2017/746 (EU IVDR)), which became applicable on May 26, 2022, establishes a new legislative framework for in vitro diagnostic devices that are used in certain circumstances, and includes a rule-based classification and quality and safety standards. The EU IVDR, where applicable to DD's services, could impact DD's ability to support trials, result in increased costs and administrative and legal actions, and have an adverse effect.

Failure to comply with U.S., state, local or international environmental, health and safety laws and regulations, including the U.S. Occupational Safety and Health Administration Act and the U.S. Needlestick Safety and Prevention Act, could result in fines, penalties and loss of licensure, and have a material adverse effect upon the Company.

As previously discussed in Item 1 of Part I of this Annual Report, the Company is subject to licensing and regulation under laws and regulations relating to the protection of the environment and human health and safety, including laws and regulations relating to the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials, as well as regulations relating to the safety and health of laboratory employees. Failure to comply with these laws and regulations could subject the Company to denial of the right to conduct business, fines, criminal penalties and/or other enforcement actions that would have a material adverse effect on its business. In addition, compliance with future legislation could impose additional requirements on the Company that may be costly.

Risks Related to Technology and Cybersecurity

Failure to maintain the security of customer-related information or compliance with security requirements could damage the Company’s reputation with customers, cause it to incur substantial additional costs and become subject to litigation and enforcement actions.

The Company receives and stores certain personal and financial information about its customers. In addition, the Company depends upon the secure transmission of confidential information over public networks, including information permitting cashless payments. The Company also works with third-party service providers and vendors that provide technology systems and services that are used in connection with the receipt, storage, and transmission of customer personal and financial information. A compromise in the Company’s security systems, or those of the Company's third-party service providers and vendors, that results in customer personal information being obtained by unauthorized persons, or the Company’s or a third party's failure to comply with security requirements for financial transactions, including security standards for payment cards (e.g., the Payment Card Industry Data Security Standard), could adversely affect the Company’s reputation with its customers and others, as well as the Company’s results of operations, financial condition and liquidity. It could also result in litigation against the Company and the imposition of fines and penalties. For example, in connection with the AMCA Incident the Company has incurred, and expects to continue to incur, costs, and the Company is involved in pending and threatened litigation, as well as various government and regulatory inquiries and processes. For additional information about the AMCA Incident, see Note 14 Commitments and Contingencies to the Consolidated Financial Statements of Part III of the Annual Report.

Failure in the Company’s information technology systems or delays or failures in the development and implementation of new systems or updates or enhancements to existing systems could disrupt the Company’s operations or customer relationships.

The Company’s operations and customer relationships depend, in part, on the continued performance of its information technology systems. A failure of the network or data-gathering procedures could impede the processing of data, delivery of databases and services, customer orders and day-to-day management of the business and could result in the corruption or loss of data. Despite network security measures and other precautions the Company has taken, including the development of disaster recovery plans, its information technology systems are potentially vulnerable to physical or electronic break-ins, computer viruses, fire, natural disaster, power loss, telecommunications failures, cybersecurity breaches and similar disruptions, and there may not be adequate protections, mitigation plans or redundant facilities available in the event of such system failures. In addition, the Company may experience system failures or interruptions as it integrates the information technology systems of newly acquired businesses. Failures or interruption of the Company’s systems in one or more of its operations could result in interruptions of service, disrupt the Company’s ability to process laboratory requisitions, perform testing, provide test results or drug development data in a timely manner and/or conduct timely billing operations. Such system failures could require the Company to transfer operations to an alternative provider of services, which could result in a delays in the delivery of products and services to customers. Additionally, significant delays in the planned delivery of system enhancements or improvements, or inadequate performance of the systems once they are complete could damage the Company's reputation and harm the business. Furthermore, failure of the Company’s information technology systems could adversely affect the Company’s business, profitability, financial condition, and reputation.

Security breaches and unauthorized access to the Company's or its customers’ data could harm the Company’s reputation and adversely affect its business.

The Company has experienced and expects to continue to experience attempts by computer programmers and hackers to attack and penetrate the Company’s layered security controls, like the 2018 ransomware attack. The Company has also experienced and expects to continue to experience similar attempts to attack and penetrate the systems of third-party suppliers and vendors to whom the Company has provided data, like the 2019 AMCA data breach. These attempts, if successful, could result in the misappropriation or compromise of personal information or proprietary or confidential information stored within the Company's systems or within the systems of third parties, create system disruptions or cause shutdowns. External actors are developing and deploying viruses, worms and other malicious software programs that attack the Company’s systems, the systems of third-parties, or otherwise exploit any security vulnerabilities. Outside parties may also attempt to fraudulently induce employees to take actions, including the release of confidential or sensitive information or to make fraudulent payments through illegal electronic spamming, phishing, spear phishing, or other tactics.

The Company has robust information security procedures and other safeguards in place, including evaluating the cybersecurity status of third-party suppliers and vendors that will have access to the Company’s data or information technology systems, which are monitored and routinely tested internally and by external parties. However, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and often are not recognized until launched against a target, the Company may be unable to anticipate all of these techniques or to implement adequate preventive

Index

measures. In addition, as cyber threats continue to evolve, the Company may be required to expend additional resources to continue to enhance the Company’s information security measures or to investigate and remediate any information security vulnerabilities. The Company’s remediation efforts may not be successful and could result in interruptions, delays or cessation of service. This could also impact the cost and availability of cyber insurance to the Company. Breaches of the Company’s or third parties' security measures and the unauthorized dissemination of personal, proprietary or confidential information about the Company or its customers or other third parties could expose customers’ private information. Such breaches could expose customers to the risk of financial or medical identity theft or expose the Company or other third parties to a risk of loss or misuse of this information, result in litigation and potential liability for the Company, damage the Company’s brand and reputation or otherwise harm the Company’s business. Any of these disruptions or breaches of security could have a material adverse effect on the Company’s business, regulatory compliance, financial condition and results of operations.

In addition, the Company faces increased cybersecurity risks due to the number of employees that continue to work remotely, which increased significantly as a result of the COVID-19 pandemic, and which remains at levels higher than prior to the pandemic as a result of changes in the workplace and to management and employee expectations. Increased levels of remote access create additional opportunities for cybercriminals to exploit vulnerabilities, and employees may be more susceptible to phishing and social engineering attempts. In addition, technological resources may become strained due to the number of remote users.

The Company depends on third parties to provide services critical to the Company's business, and depends on them to comply with applicable laws and regulations. Additionally, any breaches of the information technology systems of third parties could have a material adverse effect on the Company's operations.

The Company depends on third parties to provide services critical to the Company's business, including supplies, ground and air transport of clinical and diagnostic testing supplies and specimens, research products, and people, among other services. Third parties that provide services to the Company are subject to similar risks related to security of customer-related information and compliance with U.S., state, local, or international environmental, health and safety, and privacy and security laws and regulations as the Company. Any failure by third parties to comply with applicable laws, or any failure of third parties to provide services more generally, could have a material impact on the Company, whether because of the loss of the ability to receive services from the third parties, legal liability of the Company for the actions or inactions of third parties, or otherwise.

In addition, third parties to whom the Company outsources certain services or functions may process personal data, or other confidential information of the Company. A breach or cyber attack affecting these third parties, like the AMCA Incident, could also harm the Company's business, results of operations and reputation.

Risks Related to Legal Matters

Adverse results in material litigation matters could have a material adverse effect upon the Company’s business.

The Company is currently and may continue to be subject in the ordinary course of business to legal actions related to, among other things, intellectual property disputes, contract disputes, data and privacy issues, professional liability and employee-related matters, which may be or may become material. The Company also has received and may in the future receive inquiries and requests for information from governmental agencies and bodies, including Medicare or Medicaid payers, requesting comment and/or information on various matters, including allegations of billing irregularities, billing and pricing arrangements, or privacy practices that are brought to its attention through audits or third parties. Legal actions can result in substantial monetary damages as well as damage to the Company’s reputation with customers, which could have a material adverse effect upon its business.

The failure to successfully obtain, maintain and enforce intellectual property rights and defend against challenges to the Company’s intellectual property rights could adversely affect the Company.

Many of the Company’s services, products and processes rely on intellectual property, including patents, copyrights, trademarks and trade secrets. In some cases, that intellectual property is owned by another party and licensed to the Company, sometimes exclusively. The value of the Company’s intellectual property relies in part on the Company’s ability to maintain its proprietary rights to such intellectual property. The Company has been in the past and may be unable in the future to obtain or maintain the proprietary rights to its intellectual property, to prevent attempted infringement against its intellectual property, or to defend against claims that it is infringing on another party’s intellectual property, and the Company could be adversely affected.

For example, in October 2020, Ravgen Inc. filed a patent infringement lawsuit against the Company alleging infringement of two Ravgen-owned U.S. patents, and in September 2022, a jury rendered a verdict in favor of Ravgen on the remaining patent at issue, finding that the Company willfully infringed Ravgen's patent, and awarded damages of $272 million. Ravgen has filed post-trial motions seeking enhanced damages of up to $817 million based on the finding of willfulness, as well as

Index

attorney's fees and costs. The Company strongly disagrees with the verdict, based on a number of legal factors, and will vigorously defend the lawsuit through the appeal process. On June 4, 2021, the Company also instituted proceedings before the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office challenging the validity of the Ravgen patent at issue in the trial. In November 2022, the Patent Trial and Appeal Board issued a decision upholding the validity of the Ravgen patent, and the Company has filed an appeal of this decision.

Adverse effects resulting from the failure to successfully obtain, maintain, and enforce intellectual property rights and defend against challenges to the Company's intellectual property rights could include the Company having to abandon, alter and/or delay the deployment of products, services or processes that rely on such intellectual property; having to procure and pay for licenses from the holders of intellectual property rights that the Company seeks to use; and having to pay damages, fines, court costs and attorney's fees in connection with intellectual property litigation.

Changes in tax laws and regulations or the interpretation of such may have a significant impact on the financial position, results of operations and cash flows of the Company.

U.S. and foreign governments continue to review, reform and modify tax laws, including with respect to the Organisation for Economic Co-operation and Development’s base erosion and profit shifting initiative. Changes in tax laws and regulations could result in material changes to the domestic and foreign taxes that the Company is required to provide for and pay.

In addition, the Company is subject to regular audits with respect to its various tax returns and processes in the jurisdictions in which it operates. Errors or omissions in tax returns, process failures or differences in interpretation of tax laws by tax authorities and the Company may lead to litigation, payments of additional taxes, penalties and interest.

Contract research services in the drug development industry create liability risks.

In contracting to work on drug development trials and studies, DD faces a range of potential liabilities, including:

•Errors or omissions that create harm to clinical trial subjects during a trial or to consumers of a drug after the trial is completed and regulatory approval of the drug has been granted;

•General risks associated with clinical pharmacology facilities, including negative consequences from the administration of drugs to clinical trial participants or the professional malpractice of clinical pharmacology physicians;

•Risks that animals in DD’s facilities may be infected with diseases that may be harmful and even lethal to themselves and humans despite preventive measures contained in DD's business policies, including those for the quarantine and handling of imported animals; and

•Errors and omissions during a trial or study that may undermine the usefulness of a trial or study, or data from the trial or study or that may delay the entry of a drug to the market.

DD contracts with physicians, also referred to as investigators, to conduct the clinical trials to test new drugs on clinical trial subjects. These tests can create a risk of liability for personal injury or death to clinical trial subjects resulting from negative reactions to the drugs administered or from professional malpractice by third party investigators.

While DD endeavors to include in its contracts provisions entitling it to be indemnified and entitling it to a limitation of liability, these provisions are not always successfully obtained and, even if obtained, do not uniformly protect DD against liability arising from certain of its own actions. DD could be materially and adversely affected if it were required to pay damages or bear the costs of defending any claim that is not covered by a contractual indemnification provision, or in the event that a party which must indemnify it does not fulfill its indemnification obligations, or in the event that DD is not successful in limiting its liability or in the event that the damages and costs exceed DD's insurance coverage. DD may also be required to agree to contract provisions with clinical trial sites or its customers related to the conduct of clinical trials, and DD could be materially and adversely affected if it were required to indemnify a site or customer against claims pursuant to such contract terms. There can be no assurance that DD will be able to maintain sufficient insurance coverage on acceptable terms.

Risks Related to the COVID-19 Pandemic

The effects of the outbreak of the COVID-19 pandemic could have material adverse impacts on the Company’s business, results of operations, cash flows, and financial position.

The Company is closely monitoring the impact of the COVID-19 pandemic on all aspects of its business. Fluctuations in the number of COVID-19 cases typically result in corresponding fluctuations in the Company's COVID-19 PCR and antibody testing (COVID-19 Testing) volumes and its Base Business (operations except for COVID-19 Testing), and may have a negative effect on the Company's business and financial performance. Given the continued unpredictability pertaining to the COVID-19 pandemic, the impact on the Company's business continues to be uncertain and depends on a number of evolving factors that the Company may not be able to predict or effectively respond to.

Index

A resurgence of COVID-19, including the rise of variants, and the Company’s initiatives to help limit the spread of the illness, could impact the Company’s ability to carry out its business as usual, which could materially adversely impact its business and financial condition. The Company has incurred additional costs in order to provide for the safety of its employees and patients and the continuity of its operations.

Adverse changes in government and third-party payer regulations, reimbursement, or coverage policies (or in the interpretation of current regulations) relating to COVID-19 testing could materially impact the Company's results of operations, cash flows and financial position.

The Company incurred additional costs to implement operational changes in response to this pandemic. The COVID-19 pandemic disrupted, and along with other economic factors, a resurgence in COVID-19 could continue to disrupt, the Company’s supply chain, including its ability to secure test collection and testing supplies and equipment and personal protective equipment for its employees. For similar reasons, the COVID-19 pandemic has also adversely impacted, and may continue to adversely impact, third parties that are critical to the Company’s business, including vendors, suppliers, and business partners. These developments, and others that are difficult or impossible to predict, could materially impact the Company’s business, financial results, cash flows, and financial position.

If there is a resurgence of the pandemic, the Company may be forced to prioritize its application of resources to the continued mitigation of COVID-19, at the expense of other potentially profitable opportunities or initiatives, such as the development of new products or selected business acquisitions.

If the Company does not respond appropriately to the ongoing COVID-19 pandemic, or if the Company’s customers do not perceive its response to be adequate, the Company could suffer damage to its reputation, which could adversely affect its business.

Despite the Company’s efforts to respond to and mitigate the impact of COVID-19 on its business and operations since the global pandemic was declared on March 11, 2020, the failure of the Company to appropriately and adequately respond as the effects of the pandemic continue may cause the Company’s customers and other stakeholders to perceive the Company’s responses to the pandemic as insufficient, inadequate, or not equivalent to or better than competitors, including with respect to the availability of testing, collection kits, and the amount of time it takes for delivery of test results or fulfillment of kit orders. Factors that may be out of the Company’s control, such as the availability of equipment, supplies, and key personnel and geographical changes in demand, may impact the Company’s ability to meet customer demand and may have an adverse effect on the Company’s operations. Any such disruptions could result in negative publicity, and the Company could suffer damage to its reputation, which could adversely affect its business, results of operations, cash flows, and financial position.

All of the Company’s primary laboratory and drug development facilities have been built or improved for the purpose of providing commercial laboratory testing or drug development services. The Company believes that these existing facilities and plans for expansion are suitable and adequate and will provide sufficient production capacity for the Company's currently foreseeable level of operations. The Company believes that if it were unable to renew a lease or if a lease were to be terminated on any of the facilities it presently leases, it could find alternate space at competitive market rates and readily relocate its operations to such new locations without material disruption to its operations.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (in millions)

General

During the year ended December 31, 2022, the Company's revenues were $14.9 billion, a decrease of 7.7% from $16.1 billion in 2021. The decrease was due to lower organic revenue of 7.5% and foreign currency translation of 1.0%, partially offset by acquisitions net of divestitures of 0.8%. The 7.5% decrease in organic revenue was due to a 10.0% decrease in COVID-19 Testing, partially offset by a 2.5% increase in the Company's organic Base Business.

The Company defines organic growth as the increase in revenue excluding the year over year impact of acquisitions, divestitures, and currency. Acquisition and divestiture impact is considered for a twelve-month period following the close of each transaction. Base Business includes the Company's business operations except for COVID-19 Testing.
