Item 1A. Risk Factors

You should carefully consider all of the information set forth in this Report, including the following risk factors, before deciding to invest in any of our securities. The risks below are not the only ones that we face. Additional risks not presently known to us, or that we presently deem immaterial, may also negatively impact us. Our business, consolidated financial condition, revenues, results of operations, profitability, reputation or cash flows, or the price of our common stock, could be materially impacted by any of these factors.

This Report also includes forward-looking statements that involve risks or uncertainties. Our results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks we face described below and elsewhere. See “Cautionary Factors that May Affect Future Results” on page 42.

RISKS RELATED TO OUR BUSINESS

The U.S. healthcare system is evolving and medical laboratory testing market fundamentals are changing, and our business could be adversely impacted if we fail to adapt.

The U.S. healthcare system continues to evolve. Significant change is taking place in the healthcare system, including as discussed above under the heading The Clinical Testing Industry, beginning on page 15. For example, value-based reimbursement is increasing (e.g., UnitedHealthcare's Preferred Lab Network); CMS has set goals for value-based reimbursement to be achieved. Patients are encouraged to take increased interest in and responsibility for, and often are bearing increased responsibility for payment for, their healthcare. Healthcare industry participants are evolving and consolidating. Healthcare services increasingly are being provided by non-traditional providers (e.g., physician assistants), in non-traditional venues (e.g., retail medical clinics, urgent care centers) and using new technologies (e.g., telemedicine, digital pathology). Utilization of the healthcare system is being influenced by several factors and may result in a decline in the demand for diagnostic information services.

In addition, we believe that clinical testing market fundamentals are changing. We believe that PAMA-driven reimbursement pressure remains a catalyst for structural change in the market. We also believe that health plans and consumers increasingly are focusing on driving better value in laboratory testing services. We expect that the evolution of the healthcare industry will continue, and that industry change is likely to be extensive.

The clinical testing business is highly competitive, and if we fail to provide an appropriately priced level of service or otherwise fail to compete effectively it could have a material adverse effect on our revenues and profitability.

The clinical testing business remains a fragmented and highly competitive industry. We primarily compete with three types of clinical testing providers: other commercial clinical laboratories, IDN-affiliated laboratories and physician-office laboratories. We also compete with other providers, including anatomic pathology practices, large physician group practices and providers of consumer-initiated testing. IDNs generally maintain on-site laboratories to perform testing on their patients (inpatient or outpatient). In addition, many IDNs compete with commercial clinical laboratories for outreach (non-IDN patients) testing. IDNs may seek to leverage their relationships with community clinicians and encourage the clinicians to send their outreach testing to the IDN's laboratory. As a result of this affiliation between IDNs and community clinicians, we compete against IDN-affiliated laboratories primarily based on quality and scope of service as well as pricing. In addition, IDNs that own physician practices may encourage or require the practices to refer testing to the IDN's laboratory. In recent years, there has been a trend of IDNs acquiring physician practices, increasing the percentage of physician practices owned by IDNs. Increased IDN ownership of physician practices may enhance clinician ties to IDN-affiliated laboratories and may strengthen their competitive position. The formation of ACOs and DCEs and their approach to contracts with healthcare providers also may increase competition to provide diagnostic information services. In addition, new players have recently started to provide clinical lab testing services (e.g., employers; government agencies).

The diagnostic information services industry also is faced with changing technology and new product introductions. Competitors may compete using advanced technology, including technology that enables more convenient or cost-effective testing. Digital pathology, still in an emerging state, is an example of this. Competitors also may compete on the basis of new service offerings. Competitors also may offer testing to be performed outside of a commercial clinical laboratory, such as (1) point-of-care testing that can be performed by physicians in their offices; (2) advanced testing that can be performed by IDNs in their own laboratories; and (3) home testing that can be carried out without requiring the services of outside providers.

Government payers, such as Medicare and Medicaid, have taken steps to reduce the utilization and reimbursement of healthcare services, including clinical testing services.

We face efforts by government payers to reduce utilization of and reimbursement for diagnostic information services. One example of this is increased use of prior authorization requirements. We expect efforts to reduce reimbursements, to impose more stringent cost controls and to reduce utilization of clinical test services will continue.

Pursuant to PAMA, reimbursement rates for many clinical laboratory tests provided under Medicare were reduced from 2018 - 2020. PAMA calls for further revision of the Medicare Clinical Laboratory Fee Schedule for years after 2020, based on future surveys of market rates; reimbursement rate reduction from 2023-25 is capped by PAMA at 15% annually. PAMA's next data collection and reporting period have been delayed, most recently by federal legislation adopted in December 2021, which further delayed the reimbursement rate reductions and reporting requirements until January 1, 2023.

In addition, CMS has adopted policies limiting or excluding coverage for clinical tests that we perform. We also provide physician services that are reimbursed by Medicare under a physician fee schedule, which is subject to adjustment on an annual basis. Medicaid reimbursement varies by state and is subject to administrative and billing requirements and budget pressures.

In addition, over the last several years, the federal government has expanded its contracts with private health insurance plans for Medicare beneficiaries, called “Medicare Advantage” programs, and has encouraged such beneficiaries to switch from the traditional programs to the private programs. There has been growth of health insurance plans offering Medicare Advantage programs, and of beneficiary enrollment in these programs. States have mandated that Medicaid beneficiaries enroll in private managed care arrangements. In addition, state budget pressures have encouraged states to consider several courses of action that may impact our business, such as delaying payments, reducing reimbursement, restricting coverage eligibility, denying claims and service coverage restrictions.

Reimbursement for Medicare services also is subject to annual reduction under the Budget Control Act of 2011, the Statutory Pay-As-You-Go Act of 2010 and the Physician Fee Schedule.

From time to time, the federal government has considered whether competitive bidding could be used to provide clinical testing services for Medicare beneficiaries at attractive rates while maintaining quality and access to care. Congress periodically considers cost-saving initiatives. These initiatives have included coinsurance for clinical testing services, co-payments for clinical testing and further laboratory physician fee schedule reductions.

Other steps taken to reduce utilization and reimbursement include requirements to obtain diagnosis codes to obtain payment, increased documentation requirements, limiting the allowable number of tests or ordering frequency, expanded prior authorization programs and otherwise increasing payment denials.

Steps to reduce utilization and reimbursement also discourage innovation and access to innovative solutions that we may offer.

Health plans and other third parties have taken steps to reduce the utilization and reimbursement of health services, including clinical testing services.

We face efforts by non-governmental third-party payers, including health plans, to reduce utilization of and reimbursement for clinical testing services. Examples include increased use of prior authorization requirements and increased denial of coverage for services. There is increased market activity regarding alternative payment models, including bundled payment models. We expect continuing efforts by third-party payers, including in their rules, practices and policies, to reduce reimbursements, to impose more stringent cost controls and to reduce utilization of clinical testing services. ACOs, DCEs and IDNs also may undertake efforts to reduce utilization of, or reimbursement for, diagnostic information services.

The healthcare industry has experienced a trend of consolidation among health insurance plans, resulting in fewer but larger insurance plans with significant bargaining power to negotiate fee arrangements with healthcare providers, including clinical testing providers. The increased consolidation among health plans also has increased pricing transparency and their bargaining power and the potential adverse impact of ceasing to be a contracted provider with any such insurer. Health plans, and independent physician associations, may demand that clinical testing providers accept discounted fee structures or assume all or a portion of the financial risk associated with providing testing services to their members through capitated payment arrangements. Some health plans also are reviewing test coding, evaluating coverage decisions and requiring preauthorization of certain testing. There are also an increasing number of patients enrolling in consumer driven products and high deductible plans that involve greater patient cost-sharing.

Other steps taken to reduce utilization and reimbursement include requirements to obtain diagnosis codes to obtain payment, increased documentation requirements, limiting the allowable number of tests or ordering frequency, expanded prior authorization programs and otherwise increasing payment denials.

Steps to reduce utilization and reimbursement also discourage innovation and access to innovative solutions that we may offer.

Failure to develop, or acquire licenses for, new tests, technology and services could negatively impact our testing volume and revenues.

The diagnostic information services industry is faced with changing technology and new product introductions. Other companies or individuals, including our competitors, may obtain patents or other property rights that would prevent, limit or interfere with our ability to develop, perform or sell our solutions or operate our business or increase our costs. In addition, they could introduce new tests, technologies or services that may result in a decrease in the demand for our services or cause us to reduce the prices of our services. Our success in continuing to introduce new solutions, technology and services will depend, in part, on our ability to license new and improved technologies on favorable terms. We may be unable to develop or introduce new solutions or services. Other companies or individuals, including our competitors, may obtain patents or other property rights on tests or processes that we may be performing, that could prevent, limit or interfere with our ability to develop, perform or sell our tests or operate our business. We also may be unable to continue to negotiate acceptable licensing arrangements, and arrangements that we do conclude may not yield commercially successful clinical tests. If we are unable to license these testing methods at competitive rates, our research and development costs may increase as a result. In addition, if we are unable to develop and introduce, or license, new solutions, technology and services to expand our advanced testing capabilities, our services may become outdated when compared with our competition.

Failure to establish, and perform to, appropriate quality standards, or to assure that the appropriate standard of quality is observed in the performance of our diagnostic information services, could adversely affect the results of our operations and adversely impact our reputation.

The provision of diagnostic information services involves certain inherent risks. The services that we provide are intended to provide information in providing patient care. Therefore, users of our services may have a greater sensitivity to errors than the users of services or products that are intended for other purposes.

Negligence in performing our services can lead to injury or other adverse events. We may be sued under physician liability or other liability law for acts or omissions by our pathologists, laboratory personnel and IDN employees who are under the supervision of our IDN-based pathologists. We are subject to the attendant risk of substantial damages awards and risk to our reputation.

RISKS RELATED TO CHANGE IN PUBLIC POLICY

AND THE REGULATORY AND LEGAL ENVIRONMENT

We are subject to numerous legal and regulatory requirements governing our activities, and we may face substantial fines and penalties, and our business activities may be impacted, if we fail to comply.

Our business is subject to or impacted by extensive and frequently changing laws and regulations in the United States (including at both the federal and state levels) and the other jurisdictions in which we engage in business. While we seek to conduct our business in compliance with all applicable laws, many of the laws and regulations applicable to us are vague or indefinite and have not been interpreted by the courts, including many of those relating to:

•billing and reimbursement of clinical testing;

•certification or licensure of clinical laboratories;

•the anti-self-referral and anti-kickback laws and regulations;

•the laws and regulations administered by the FDA;

•the corporate practice of medicine;

•operational, personnel and quality requirements intended to ensure that clinical testing services are accurate, reliable and timely;

•physician fee splitting;

•relationships with physicians and IDNs;

•safety and health of laboratory employees; and

•handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials.

These laws and regulations may be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that could require us to make changes in our operations, including our pricing and/or billing practices. We may not be able to maintain, renew or secure required permits, licenses or any other regulatory approvals needed to operate our business or commercialize our services. If we fail to comply with applicable laws and regulations, or if we fail to maintain, renew or obtain necessary permits, licenses and approvals, we could suffer civil and criminal penalties, fines, exclusion from participation in

35

governmental healthcare programs and the loss of various licenses, certificates and authorizations necessary to operate our business, as well as incur additional liabilities from third-party claims. If any of the foregoing were to occur, our reputation could be damaged and important business relationships with third parties could be adversely affected.

We regularly receive requests for information, and occasionally subpoenas, from governmental authorities. We also are subject from time to time to qui tam claims brought by former employees or other “whistleblowers.” The federal and state governments continue aggressive enforcement efforts against perceived healthcare fraud. Legislative provisions relating to healthcare fraud and abuse provide government enforcement personnel substantial funding, powers, penalties and remedies to pursue suspected cases of fraud and abuse. In addition, the government has substantial leverage in negotiating settlements since the amount of potential damages far exceeds the rates at which we are reimbursed for our services, and the government has the remedy of excluding a non-compliant provider from participation in the Medicare and Medicaid programs. Regardless of merit or eventual outcome, these types of investigations and related litigation can result in:

•diversion of management time and attention;

•expenditure of large amounts of cash on legal fees, costs and payment of damages;

•increases to our administrative, billing or other operating costs;

•limitations on our ability to continue some of our operations;

•enforcement actions, fines and penalties or the assertion of private litigation claims and damages;

•decreases to the amount of reimbursement related to diagnostic information services performed;

•adverse affects to important business relationships with third parties;

•decreased demand for our services; and/or

•injury to our reputation.

Changes in applicable laws and regulations may result in existing practices becoming more restricted, or subject our existing or proposed services to additional costs, delay, modification, withdrawal or reconsideration. Such changes also could require us to modify our business objectives.

Our business could be adversely impacted by the FDA's approach to regulation.

The FDA has regulatory responsibility over, among other areas, instruments, software, test kits, reagents and other devices used by clinical laboratories to perform diagnostic testing in the U.S. A number of tests we develop internally are offered as LDTs. The FDA has claimed regulatory authority over all LDTs, but has stated that it exercised enforcement discretion with regard to most LDTs performed by high complexity CLIA-certified laboratories.

As the FDA moves to regulate more clinical laboratory testing, its approach to regulation is impacting industry practices and participants, new competitors may enter the industry, and competition may come in new forms.

Legislation introduced in Congress would enable the FDA to regulate LDTs, in vitro diagnostics, software and other items used in the diagnosis of disease. The FDA and the U. S. Department of Health and Human Services also have expressed views regarding the regulation of LDTs. Either new law or a revised approach to regulation of LDTs could have a significant impact on the clinical laboratory testing industry, including regulating LDTs in new ways, while creating avenues of opportunity and competition regarding clinical laboratory testing. New competitors may enter the industry, and competition may come in new forms.

Pursuant to the 21st Century Cures Act, the FDA issued final guidance regarding its position on the regulation of clinical decision software, which may be used in connection with LDTs. The guidance attempts to clarify whether FDA approval of certain software is required. It has been used by the FDA, in part, to assert authority over the annotation software aspects of pharmacogenetic testing services.

Failure to accurately bill for our services, or to comply with applicable laws relating to government healthcare programs, could have a material adverse effect on our business.

Billing for diagnostic information services is complex and subject to extensive and non-uniform rules and administrative requirements. Depending on the billing arrangement and applicable law, we bill various payers, such as patients, insurance companies, Medicare, Medicaid, clinicians, IDNs and employer groups. The majority of billing and related operations for our Company are being provided by a third party under the Company's oversight. Failure to accurately bill for our services could have a material adverse effect on our business. In addition, failure to comply with applicable laws relating to billing government healthcare programs may result in various consequences, including: civil and criminal fines and penalties,

36

exclusion from participation in governmental healthcare programs and the loss of various licenses, certificates and authorizations necessary to operate our business, as well as incur additional liabilities from third-party claims, all of which could have a material adverse effect on our business. Certain violations of these laws may also provide the basis for a civil remedy under the federal False Claims Act, including fines and damages of up to three times the amount claimed. The qui tam provisions of the federal False Claims Act and similar provisions in certain state false claims acts allow private individuals to bring lawsuits against healthcare companies on behalf of government payers, private payers and/or patients alleging inappropriate billing practices.

Although we believe that we are in compliance, in all material respects, with applicable laws and regulations, there can be no assurance that a regulatory agency or tribunal would not reach a different conclusion. The federal or state government may bring claims based on our current practices, which we believe are lawful. The federal and state governments have substantial leverage in negotiating settlements since the amount of potential damages and fines far exceeds the rates at which we are reimbursed, and the government has the remedy of excluding a non-compliant provider from participation in the Medicare and Medicaid programs. We believe that federal and state governments continue aggressive enforcement efforts against perceived healthcare fraud. Legislative provisions relating to healthcare fraud and abuse provide government enforcement personnel with substantial funding, powers, penalties and remedies to pursue suspected cases of fraud and abuse.

We are subject to numerous political, legal, operational and other risks as a result of our international operations which could impact our business in many ways.

Our international operations increase our exposure to risks inherent in doing business in non-U.S. markets, which may vary by market and include: intellectual property legal protections and remedies; weak legal systems which may, among other things, affect our ability to enforce contractual rights; trade regulations and procedures and actions affecting approval, production, pricing, reimbursement and marketing of services; and challenges based on differing languages and cultures. International operations also require us to devote management resources to implement our controls and systems in new markets, and to comply with the U.S. Foreign Corrupt Practices Act and similar anti-corruption laws in non-U.S. jurisdictions.

We may be unable to obtain, maintain or enforce our intellectual property rights and may be subject to intellectual property litigation that could adversely impact our business.

We may be unable to obtain or maintain adequate patent or other proprietary rights for our solutions or services or to successfully enforce our proprietary rights. In addition, we may be subject to intellectual property litigation, and we may be found to infringe on the proprietary rights of others, which could force us to do one or more of the following:

•cease developing, performing or selling solutions or services that incorporate the challenged intellectual property;

•obtain and pay for licenses from the holder of the infringed intellectual property right;

•redesign or re-engineer our tests;

•change our business processes; or

•pay substantial damages, court costs and attorneys' fees, including potentially increased damages for any infringement held to be willful.

Adverse results in material litigation could have an adverse financial impact and an adverse impact on our client base and reputation.

We are involved in various legal proceedings arising in the ordinary course of business including, among other things, disputes as to intellectual property, professional liability and employee-related matters, as well as inquiries from governmental

37

agencies and Medicare or Medicaid carriers. Some proceedings against us involve claims that are substantial in amount and could divert management's attention from operations. These proceedings also may result in substantial monetary damages.

U.S. Government rules and regulations concerning mandatory COVID-19 vaccination of U.S.-based employees of companies that work on or in support of federal government contracts, or other COVID-19 vaccine mandates, could have a material adverse impact on our business and consolidated results of operations.

In September 2021, President Biden issued an executive order requiring all employers with U.S. Government contracts to ensure that their U.S.-based employees, contractors and subcontractors, that work on or in support of U.S. government contracts, are fully vaccinated against COVID-19 as required by the executive order. The executive order is being challenged in courts and is currently not in effect. However, other federal, state and local government vaccine mandates are in effect; some of these mandates have application to the Company (directly or indirectly), others do not have application to the Company. Further, additional vaccine and testing mandates have been and may in the future be announced by private parties (such as contract counterparties) and in other jurisdictions in which we operate; such mandates may conflict with each other. Requirements to mandate COVID-19 vaccination of all or significant portions of our workforce could result in labor disruptions, employee attrition, difficulty in satisfying future labor needs and sanctions or penalties.

RISKS RELATED TO OUR INDEBTEDNESS

Our outstanding debt may impair our financial and operating flexibility.

As of December 31, 2021, we had approximately $4.0 billion of debt outstanding. Other than credit facilities in the normal course of business, we do not have any off-balance sheet financing arrangements in place or available. Our debt agreements contain various restrictive covenants. These restrictions could limit our ability to use operating cash flow in other areas of our business because we must use a portion of these funds to make principal and interest payments on our debt. We have obtained ratings on our public debt from Standard and Poor's, Moody's Investor Services and Fitch Ratings. There can be no assurance that any rating so assigned will remain for any given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if in that rating agency's judgment future circumstances relating to the basis of the rating, such as adverse changes in our Company or our industry, so warrant. If such ratings are lowered, our borrowing costs could increase. Changes in our credit ratings, however, do not require repayment or acceleration of any of our debt.

Borrowings under our credit facilities may be made at interest rates that are based on the London Interbank Offered Rate (“LIBOR”), which is a widely used benchmark for establishing interest rates globally. As a result of concerns regarding the accuracy of the calculation of LIBOR, the United Kingdom’s Financial Conduct Authority announced that it intends to no longer compel member banks to submit rates used to calculate LIBOR after December 31, 2021. These reforms may cause LIBOR to cease to exist as a reference rate. A committee established by the Federal Reserve Board announced a new index, based on overnight repurchase agreements collateralized by U.S. Treasury securities, as an alternative to LIBOR; other jurisdictions have proposed different alternatives. At this time, it is not possible to predict the replacement rate for U.S. dollar LIBOR (which is the LIBOR rate that we most frequently rely on), and the consequences to us cannot be predicted. While we expect to be able to transition all LIBOR-based instruments and contracts to an alternative reference rate upon the cessation of LIBOR, there is no guarantee that we will be able to do so. Changes in market interest rates may negatively influence our financing costs and the valuation of derivative instruments.

We or our subsidiaries may incur additional indebtedness in the future. Our ability to make principal and interest payments will depend on our ability to generate cash in the future. If we incur additional debt, a greater portion of our cash flows may be needed to satisfy our debt service obligations and if we do not generate sufficient cash to meet our debt service requirements, we may need to seek additional financing. In that case, it may be more difficult, or we may be unable, to obtain financing on terms that are acceptable to us. As a result, we would be more vulnerable to general adverse economic, industry and capital markets conditions as well as the other risks associated with indebtedness.

RISKS RELATED TO OUR OPERATIONS

The development of new technologies (including artificial intelligence technologies) may impact the healthcare industry, and the development of new, more cost-effective solutions that can be performed by our customers or by patients, and the continued internalization of testing by IDNs or clinicians, could negatively impact our testing volume and revenues.

The diagnostic information services industry is faced with changing technology and new product introductions, including technology that enables more convenient or cost-effective testing. For example, digital pathology is an emerging

38

technology that may change the practice of pathology. Information technology that includes self-learning or "artificial intelligence" features is growing and may impact the healthcare industry.

Competitors also may offer testing to be performed outside of a commercial clinical laboratory, such as (1) point-of-care testing that can be performed by clinicians in their offices; (2) complex testing that can be performed by IDNs in their own laboratories; and (3) home testing that can be carried out without requiring the services of outside providers. Advances in technology also may lead to the need for less frequent testing. Further, diagnostic tests approved or cleared by the FDA for home use are automatically deemed to be “waived” tests under CLIA and may be performed by consumers in their homes; test kit manufacturers could seek to increase sales to patients of such test kits.

Some traditional customers for anatomic pathology services, including specialty physicians that generate biopsies through surgical procedures, such as dermatologists, gastroenterologists, urologists and oncologists, are consolidating, have added in-office histology labs or have retained pathologists to read cases on site. IDNs also are internalizing clinical laboratory testing, including some non-routine and advanced testing. Internalization of testing may reduce demand for services previously referred to outside service providers, such as the Company.

Hardware and software failures or delays in our information technology systems, including failures resulting from our systems conversions or otherwise, could disrupt our operations and cause the loss of confidential information, customers and business opportunities or otherwise adversely impact our business.

IT systems are used extensively in virtually all aspects of our business, including clinical testing, test reporting, billing, customer service, logistics and management of medical data. Our success depends, in part, on the continued and uninterrupted performance of our IT systems. A failure or delay in our IT systems could impede our ability to serve our customers and patients and protect their confidential data. Despite redundancy and backup measures and precautions that we have implemented, our IT systems may be vulnerable to damage, disruptions and shutdown from a variety of sources, including telecommunications or network failures, system conversion or standardization initiatives, human acts and natural disasters. These issues can also arise as a result of failures by third parties with whom we do business and over which we have limited control. Any disruption or failure of our IT systems could have a material impact on our ability to serve our customers and patients, including negatively affecting our reputation in the marketplace.

Our business could be negatively affected if we are unable to continue to strengthen our efficiency.

It is important that we continue to strengthen our efficiency to promote our competitive position and to enable us to mitigate the impact on our profitability of steps taken by government payers and health insurers to reduce the utilization and reimbursement of healthcare services, including diagnostic information services.

Our business operations and reputation may be materially impaired if we do not comply with privacy laws or information security policies.

In our business, we collect, generate, process or maintain sensitive information, such as patient data and other personal information. If we do use or not adequately safeguard that information in compliance with applicable requirements under federal, state and international laws, or if it were disclosed to persons or entities that should not have access to it, our business could be materially impaired, our reputation could suffer and we could be subject to fines, penalties and litigation. In the event of a data security breach, we may be subject to notification obligations, litigation and governmental investigation or sanctions, and may suffer reputational damage, which could have an adverse impact on our business.

We are subject to laws and regulations regarding protecting the security and privacy of certain healthcare and personal information, including: (a) the federal Health Insurance Portability and Accountability Act and the regulations thereunder, which establish (i) a complex regulatory framework including requirements for safeguarding protected health information and (ii) comprehensive federal standards regarding the uses and disclosures of protected health information; (b) state laws, including the California Consumer Privacy Act and similar laws in other states; and (c) laws outside the U.S., including the European Union's General Data Protection Regulation.

39

The IT systems that we rely on may be subject to unauthorized tampering, cyberattack or other security breach.

Our IT systems have been and are subject to potential cyberattacks, tampering or other security breaches. These attacks, if successful, could result in shutdowns or significant disruptions of our IT systems and/or in unauthorized persons exfiltrating and misappropriating intellectual property and other confidential information, including patient and employee data that we collect, transmit and store on and through our IT systems.

External actors may develop and deploy viruses, other malicious software programs, ransomware attacks, distributed denial of service attacks or other attempts to harm or obtain unauthorized access to our systems. External actors may also deploy programs targeting our employees which are designed to attack our IT systems or otherwise exploit security vulnerabilities through programs such as electronic spamming, phishing, smishing, spear phishing or similar tactics. As a result of the difficulty in detecting many of these attacks, intrusions and breaches, failures or losses may be repeated or compounded before they are discovered or rectified, which could further increase these costs and consequences.

Although the Company has robust security measures implemented, which are monitored and routinely tested both by internal resources and external parties, cyber threats against us continue to evolve and may not be recognized until after an incident. In August 2021, ReproSource, our subsidiary, experienced a data security incident in which an unauthorized party may have accessed or acquired protected health information and personally identifiable information of ReproSource patients (in connection with the incident, ReproSource discovered and contained ransomware). The Company’s other systems were not impacted or compromised by this incident. Although the attacks we have experienced have not materially disrupted, interrupted, damaged or shutdown the Company's IT systems, or materially disrupted the Company's performance of its business, the mitigation or remediation efforts that we have undertaken, and may undertake in the future, require the attention of management and expenditures of resources, which can be significant. There can be no assurance that the Company can anticipate all evolving future attacks, viruses or intrusions, implement adequate preventative measures, or remediate any security vulnerabilities. If our IT systems are successfully attacked, it could result in major disruption of our business, compromise confidential information, and result in litigation and potential liability for the Company, government investigation, significant damage to our reputation or otherwise adversely affect our business.

In addition, third parties to whom we outsource certain of our services or functions, or with whom we interface, store or process confidential patient and employee data or other confidential information, as well as those third parties’ providers, are also subject to the risks outlined above. For example, in June 2019, the Company reported that Retrieval-Masters Creditors Bureau, Inc./American Medical Collection Agency (“AMCA”), informed the Company about a data security incident involving AMCA. AMCA, which provided debt collection services for a company that provides revenue management services to the Company, informed the Company in May 2019 that AMCA had learned that an unauthorized user had access to AMCA’s system during 2018 and 2019. AMCA’s affected system included financial, medical and other personal information. The Company’s systems or databases were not involved in this incident. A breach or attack affecting third parties with whom we engage could also harm our business, results of operations and reputation and subject us to liability.

We have taken, and continue to take, precautionary measures to reduce the risk of, and detect and respond to, future cyber threats, and prevent or minimize vulnerabilities in our IT systems, including the loss or theft of intellectual property, patient and employee data or other confidential information that we obtain and store on our systems. We also have taken, and will continue to take, measures to assess the cybersecurity protections used by third parties to whom we outsource certain of our services or functions, or with whom we interface, store or process confidential patient and employee data or other confidential information. In addition, we collaborate with government agencies regarding potential cyber threats and have worked with firms that have cyber security expertise to evaluate our systems and the attacks we experience and strengthen our systems. There can be no assurances that our precautionary measures or measures used by our third party providers will prevent, contain or successfully defend against cyber or information security threats that could have a significant impact on our business, results of operations and reputation and subject us to liability.

Our ability to attract and retain qualified employees is critical to the success of our business and the failure to do so may materially adversely affect our performance.

The supply of qualified technical, managerial and other personnel, including phlebotomists and processors, is currently constrained; competition for qualified employees, even across different industries, is intense, including as individuals leave the job market. We may lose, or fail to attract and retain, key management personnel, or qualified skilled technical, professional or other employees.

40

Business development activities are inherently risky and integrating our operations with businesses we acquire may be difficult.

We plan selectively to enhance our business from time to time through business development activities, such as acquisitions, licensing arrangements, investments and alliances. However, these plans are subject to the availability of appropriate opportunities and competition from other companies seeking similar opportunities. Moreover, the success of any such effort may be affected by a number of factors, including our ability to properly assess and value the potential business opportunity, and to integrate it into our business. The success of our strategic alliances depends not only on our contributions and capabilities, but also on the property, resources, efforts and skills contributed by our strategic partners. Further, disputes may arise with strategic partners, due to conflicting priorities or conflicts of interests.

Acquisitions are not all the same (e.g., asset acquisitions differ from acquisitions of equity interests); different acquisitions offer different risks. Acquisitions may involve the integration of a separate company that has different systems, processes, policies and cultures. Integration of acquisitions involves a number of risks including the diversion of management's attention to the assimilation of the operations of assets or businesses we have acquired, difficulties in the integration of operations and systems and the realization of potential operating synergies, the assimilation and retention of the personnel of the acquired businesses, challenges in retaining the customers of the combined businesses, and potential adverse effects on operating results. The process of combining acquisitions may be disruptive to our businesses and may cause an interruption of, or a loss of momentum in, such businesses as a result of the following difficulties, among others:

•loss of key customers or employees;

•difficulty in standardizing information and other systems;

•difficulty in consolidating facilities and infrastructure;

•failure to maintain the quality or timeliness of services that our Company has historically provided;

•diversion of management's attention from the day-to-day business of our Company as a result of the need to deal with the foregoing disruptions and difficulties; and

•the added costs of dealing with such disruptions.

If we are unable successfully to integrate strategic acquisitions in a timely manner, our business and our growth strategies could be negatively affected. Even if we are able to successfully complete the integration of the operations of other assets or businesses we may acquire in the future, we may not be able to realize all or any of the benefits that we expect to result from such integration, either in monetary terms or in a timely manner.

Our operations may be adversely impacted by the effects of natural disasters such as hurricanes and earthquakes, public health emergencies and health pandemics, hostilities or acts of terrorism and other criminal activities.

We operate facilities across the United States, and consumers frequently visit our facilities in person. The ability of our employees and consumers to access our facilities may be adversely impacted by the effects of extreme weather events and natural disasters, such as hurricanes, earthquakes, tropical storms, floods, fires, earthquakes or other extreme weather conditions, including major winter storms, droughts and heat waves, whether as a result of climate change or otherwise; public health emergencies and health pandemics; hostilities or acts of terrorism or other activities. Although we maintain a business continuity program to prepare for and respond to such events, because of their unpredictable nature, these events may limit or interrupt our ability to conduct operations. Additionally, such events may interrupt our ability to transport specimens, to receive materials from our suppliers or otherwise to provide our services. These events also may result in a decline in the number of patients who seek clinical testing services or in our employees' ability to perform their job duties.

The COVID-19 pandemic has significantly affected our consolidated results of operations, financial position and cash flows, and may continue to do so.

A pandemic caused by a novel strain of coronavirus (COVID-19) continues to severely impact the economy of the United States and other countries around the world. Federal, state and local governmental authorities in the United States have implemented numerous policies and initiatives to try and reduce the transmission of COVID-19, such as travel bans and restrictions, quarantines, shelter-in-place orders, business shutdowns, and vaccination and masking mandates. These policies and initiatives have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, customers closing or severely curtailing their operations (voluntarily or in response to government orders), increased unemployment, constrained labor supply and loss of healthcare insurance, and the adoption of work-from-home policies, all of which have had, and we believe will continue to have, an impact on our consolidated results of operations, financial position and cash flows.

Due to the COVID-19 pandemic, we have experienced significant volatility, including periods of material decline compared to prior year periods, in testing volume in our base business (which excludes COVID-19 molecular and antibody testing) and this volatility, including periods of material decline, could continue. Although we also have experienced heavy demand for COVID-19 molecular testing as a result of the COVID-19 pandemic, which has had a positive impact on our overall testing volume, the duration and level of the demand for, and reimbursement for, COVID-19 molecular testing is uncertain.

We may also experience an adverse impact on cash collections and labor supply and supply chain disruptions, including shortages, delays and price increases in testing equipment and supplies, as a result of the impact of the COVID-19 pandemic. A number of suppliers and manufacturers we rely upon have been experiencing and may continue to experience disruptions and delays, as a result of ongoing raw material and labor shortages, supply challenges, and business limitations or shutdowns resulting from the COVID-19 pandemic, which may prevent us from obtaining equipment and supplies in a timely manner or at a reasonable price. The COVID-19 pandemic has also caused significant disruptions in transport and logistics services as a result of facility closures, labor shortages or other challenges, which may affect our ability to transport specimens, receive supplies or materials from our suppliers or otherwise provide our services. These conditions may continue or deteriorate in the future. Any of these events could have an adverse impact on our business, consolidated results of operation, financial position and cash flows.

We believe the COVID-19 pandemic’s adverse impact on our consolidated results of operations, financial position and cash flows will be primarily driven by: the severity and duration of the COVID-19 pandemic (including any variants); the COVID-19 pandemic’s impact on the U.S. healthcare system and the U.S. economy; the timing, scope and effectiveness of federal, state and local governmental responses; and effective and comprehensive COVID-19 vaccination across the U.S. These primary drivers are beyond our knowledge and control and will change over time, and as a result, at this time we cannot reasonably estimate the adverse impact the COVID-19 pandemic will have on our businesses, consolidated results of operations, financial position and cash flows, and the adverse impact may be material.

Our business also may be impacted by changes in the severity of the COVID-19 pandemic at different times in the various cities and regions where we operate and offer services, and by challenges faced in implementing nationwide COVID-19 vaccinations, including the degree to which the public is vaccinated and the effectiveness of vaccines at preventing infection or illness in connection with new or existing variants of COVID-19. Even after the COVID-19 pandemic has moderated and business conditions have eased, we may continue to experience similar adverse effects to our businesses, consolidated results of operations, financial position and cash flows arising from long-term changes in behavior by consumers or other healthcare system participants and resulting from a recessionary economic environment that may persist. The impact that the COVID-19 pandemic will have on our businesses, consolidated results of operations, financial position and cash flows could exacerbate other risks identified in this Report.
