## No Match in Current: The spin-off of Fortrea may not achieve the intended results.

*This section from the 2025 filing does not have a high-confidence textual match in 2026. It may have been removed, merged, or substantially reworded.*

On June 30, 2023, the Company completed the previously announced spin-off of Fortrea. The Spin-off poses risks and challenges that could impact the Company's business, including, but not limited to, the failure to receive tax-free treatment for U.S. federal income purposes, and potential exposure to unexpected claims, liabilities, or costs under the Company's agreements with Fortrea in connection with the Spin-off. 35 35 35 Index Index

## No Match in Current: Any cybersecurity incidents affecting the information technology systems of third parties that provide services to the Company could have a material adverse effect on the Company's operations.

*This section from the 2025 filing does not have a high-confidence textual match in 2026. It may have been removed, merged, or substantially reworded.*

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 and depends on them to comply with applicable laws and regulations. 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 cybersecurity incident affecting these third parties, like the AMCA Incident, could also harm the Company's business, results of operations and reputation.

## Modified: 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.

**Key changes:**

- Reworded sentence: "To limit the Company's exposure to interest rate and currency exchange fluctuations, the Company enters into financial swaps and hedging arrangements, with various counterparties."

**Prior (2025):**

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.

**Current (2026):**

To limit the Company's exposure to interest rate and currency exchange fluctuations, the Company enters into financial swaps and hedging arrangements, with various counterparties. In addition to any risk related to the counterparties, there can be no assurance that this hedging strategy will be effective in insulating the Company from the risk associated with the underlying transactions or that the Company will not have to pay additional amounts upon settlement.

## Modified: Failure to develop or acquire licenses for new or improved testing technologies, or the Company's customers using new technologies to replace offerings currently provided by the Company could adversely affect its business.

**Key changes:**

- Removed sentence: "From time to time, manufacturers discontinue or recall reagents, test kits, or instruments used by the Company to perform laboratory testing."
- Removed sentence: "Such discontinuations or recalls could adversely affect the Company's costs, testing volume and revenue."
- Reworded sentence: "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."
- Reworded sentence: "Similarly, application of AI to testing could reduce demand for the Company's services, or competitors could adopt use of these technologies and derive benefits from them sooner than the Company, which could adversely affect the Company's business."
- Added sentence: "23 23 23 TABLE OF CONTENTS TABLE OF CONTENTS"

**Prior (2025):**

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 the introduction of new and improved test offerings. 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 31 31 31 Index Index 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 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 and testing volume and revenue may be materially and adversely affected. In addition, advances in technology may lead to the development of more technologies, such as point-of-care testing equipment, that can be operated by healthcare providers in their offices or by patients themselves without requiring the services of commercial 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. Similarly, application of artificial intelligence to testing could reduce demand for the Company's services, or competitors could adopt use of these technologies and derive benefits from them sooner than the Company. 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 by regulatory agencies for home or physician office use to both physicians and patients. Increased approval and use of such 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.

## Modified: Increased competition, including price competition, could have an adverse effect on the Company's revenues and profitability.

**Key changes:**

- Reworded sentence: "As further described in Item 1 and Item 1A of Part I of this Annual Report, both Dx and BLS operate in highly competitive industries and selection of a commercial laboratory or a drug development partner is based on a number of competitive factors."
- Reworded sentence: "Dx and BLS compete against a wide range of businesses, 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."

**Prior (2025):**

As further described in Item 1 and Item 1A of Part I of this Annual Report, both Dx and BLS operate in competitive industries. The commercial laboratory business is intensely competitive in terms of price, service, specialty offerings, and the type and number of commercial laboratories. Dx and BLS compete against a wide range of businesses, 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. In addition, BLS's services periodically experience periods of increased price competition that may have an adverse effect on the segment's profitability and consolidated revenues and net earnings.

**Current (2026):**

## Modified: General or macro-economic factors and significant fluctuations in economic conditions in the U.S. and globally may have a material adverse effect on the Company.

**Key changes:**

- Reworded sentence: "The Company's business depends on sustained demand for diagnostic testing and biopharma laboratory services by patients, physicians, hospitals, MCOs, CROs, pharmaceutical, biotechnology, medical device companies, and others."

**Prior (2025):**

The Company's operations are dependent upon ongoing demand for diagnostic testing and biopharma laboratory services by patients, physicians, hospitals, MCOs, pharmaceutical, biotechnology and medical device companies and others. Significant changes in global economic conditions, and an increase in the costs of goods and services, could negatively impact testing volumes, the demand for biopharma laboratory services, cash collections, profitability, and the availability and cost of credit. 29 29 29 Index Index Pressures on and uncertainty surrounding the U.S. federal government's budget, and potential changes in budgetary priorities, could adversely affect the funding for government programs that comprise a portion of the Company's revenues. In addition, uncertainty in the credit markets and interest rate volatility could reduce the availability and increase the cost of credit and impact the Company's ability to meet its financing needs in the future.

**Current (2026):**

The Company's business depends on sustained demand for diagnostic testing and biopharma laboratory services by patients, physicians, hospitals, MCOs, CROs, pharmaceutical, biotechnology, medical device companies, and others. Significant changes in global economic conditions, inflationary pressures, and credit market volatility could negatively affect testing volumes, the demand for biopharma laboratory services, cash collections, profitability, and access to financing. Pressure on and uncertainty surrounding the U.S. federal government budget and potential changes in budgeting priorities could adversely affect the funding for government programs that comprise a portion of the Company's revenue. In addition, uncertainty in the credit markets and interest rate volatility could reduce the availability and increase the cost of credit and impact the Company's ability to meet its financing needs in the future.

## Modified: The Company might not be able to engage in certain desirable capital raising or strategic transactions as a result of the Spin-off and may not achieve its intended results.

**Key changes:**

- Reworded sentence: "To preserve, for U.S."

**Prior (2025):**

The Company's ability to engage in certain transactions could be limited or restricted in order to preserve, for U.S. federal income tax purposes, the tax-free qualification of the Fortrea spin-off and certain related transactions under Sections 355 and 368(a)(1)(D) of the Internal Revenue Code. Even if the Spin-off and certain related transactions otherwise qualify for tax-free treatment under Section 355 of the Code, they may result in corporate-level taxable gain to the Company if there is a 50% or greater change in ownership, by vote or value, of shares of the Company's stock, Fortrea's stock, or the stock of a successor of either occurring as part of a plan or series of related transactions that includes the Spin-off, which is generally presumed to include any acquisitions or issuances of stock within two years of the Spin-off. To avoid realizing such taxable gain, the Company may be restricted or limited in its capital-raising or in the strategic transactions that it elects to pursue during such time period.

**Current (2026):**

To preserve, for U.S. federal income tax purposes, the tax-free qualification of the Spin-off and certain related transactions under Sections 355 and 368(a)(1)(D) of the U.S. Internal Revenue Code, the Company may be limited or restricted in pursing certain transactions. Even if the Spin-off and certain related transactions otherwise qualify for tax-free treatment under Section 355 of the Code, they may result in corporate-level gain to the Company if there is a 50% or greater change in ownership, by vote or value, of the shares of the Company's stock, Fortrea's stock, or the stock of a successor of either occurring as part of a plan or series of related transactions that includes the Spin-off, which is generally presumed to include any acquisitions or issues of stock within two years of the Spin-off. To avoid realizing such taxable gain, the Company may be restricted or limited in its capital raising or in the strategic transactions that it elects to pursue during such time period. Additionally, the Spin-off presents risks that could affect the Company's business, including exposure to unexpected claims, liabilities, or costs under the Company's agreements with Fortrea in connection with the Spin-off.

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

**Key changes:**

- Reworded sentence: "Billing for laboratory services is a complex process due to varying billing requirements across different payers, including physicians, patients, health plans, Medicare, and Medicaid."

**Prior (2025):**

Billing for laboratory services is a complex process. Laboratories bill many different payers, including doctors, patients, health plans, Medicare, Medicaid, and employer groups, all of which have different billing requirements. A material increase in Dx's days sales outstanding level, which could be caused by multiple reasons due to the complexity of billing for laboratory services, could have an adverse effect on the Company's business, including potentially increasing its bad debt rate and decreasing its cash flows. Although BLS 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 BLS's days sales outstanding could have an adverse effect on the Company's business, including potentially decreasing its cash flows.

**Current (2026):**

Billing for laboratory services is a complex process due to varying billing requirements across different payers, including physicians, patients, health plans, Medicare, and Medicaid. A material increase in Dx's days sales outstanding level, driven by billing complexity or otherwise, could have an adverse effect on the Company's business, including potentially increasing the Company's bad debt rate and reducing cash flows. While BLS faces less billing complexity, delays in billing or collections could similarly have an adverse effect on the Company's business, including potentially decreasing cash flows.

## Modified: 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.

**Key changes:**

- Reworded sentence: "The Company relies on intellectual property - including patents, copyrights, trademarks, and trade secrets - to support many of its offerings and processes."
- Reworded sentence: "In May 2023, the court awarded Ravgen additional enhanced damages in the amount of $100.0 million, and in January 2025, the court awarded Ravgen post-verdict supplemental damages of $2.6 million, an ongoing royalty of $100 per test through the life of the patent as issue, pre- and post-judgement interest, and other relief."
- Reworded sentence: "Failure to successfully obtain, maintain, enforce, or defend intellectual property rights - or adverse outcomes in litigation - could result in the need to alter or discontinue offerings, pay significant costs, damages or licensing fees, or suffer reputational harm, any of which could materially affect the Company's business, reputational, and results of operations."

**Prior (2025):**

Many of the Company's offerings 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. In September 2022, a jury rendered a verdict in favor of Ravgen on the remaining patent at issue and awarded damages of $272.0 million. In May 2023, the court awarded Ravgen additional enhanced damages in the amount of $100.0 million, and in January 2025, the court awarded Raygen post-verdict supplemental damages of $2.6 million, an ongoing royalty of $100 per test through the life of the patent as issue, pre- and post-judgement interest, and other relief. 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 that decision was upheld on appeal before the U.S. Court of Appeals for the Federal Circuit in January 2025. 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 offerings 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, having to pay damages, fines, court costs and attorney's fees in connection with intellectual property litigation, and reputational damage.

**Current (2026):**

The Company relies on intellectual property - including patents, copyrights, trademarks, and trade secrets - to support many of its offerings and processes. Some of this intellectual property is licensed from third parties, including on an exclusive basis. The Company's ability to maintain and enforce its proprietary rights, prevent infringement, and defend claims of infringement is critical to its operations. The Company has faced, and may continue to face, challenges relating to intellectual property rights. For example, in October 2020, Ravgen Inc. filed a patent infringement lawsuit against the Company alleging infringement of two Ravgen-owned U.S. patents. In September 2022, a jury rendered a verdict in favor of Ravgen on the remaining patent at issue and awarded damages of $272.0 million. In May 2023, the court awarded Ravgen additional enhanced damages in the amount of $100.0 million, and in January 2025, the court awarded Ravgen post-verdict supplemental damages of $2.6 million, an ongoing royalty of $100 per test through the life of the patent as issue, pre- and post-judgement interest, and other relief. The Company strongly disagrees with the verdict, based on a number of legal factors, and will vigorously defend the lawsuit through the appeal process. Failure to successfully obtain, maintain, enforce, or defend intellectual property rights - or adverse outcomes in litigation - could result in the need to alter or discontinue offerings, pay significant costs, damages or licensing fees, or suffer reputational harm, any of which could materially affect the Company's business, reputational, and results of operations.

## Modified: 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.

**Key changes:**

- Reworded sentence: "The Company collects, stores, transmits, and processes personal and financial information, and works with third-party service providers in connection with such data processing activities."

**Prior (2025):**

The Company receives, stores, transmits, and processes 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, transmission, and processing of customer personal and financial information. A compromise of the Company's systems, or those of the Company's third-party service providers and vendors, that results in customer personal information being obtained or altered by unauthorized persons, or the Company's third party's failure to comply with security requirements, including but not limited to 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 (as defined below under "Cybersecurity" in Item 1C) 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 15 Commitments and Contingencies to the Consolidated Financial Statements of Part III of the Annual Report.

**Current (2026):**

The Company collects, stores, transmits, and processes personal and financial information, and works with third-party service providers in connection with such data processing activities. A compromise of the Company's or a vendor's systems that results in confidential information being acquired, accessed, or changed by unauthorized persons, or failure to meet security standards, such as the HIPAA security regulations and the Payment Card Industry Data Security Standard, could harm the Company's reputation, operations, financial condition, and liquidity, and may result in litigation, fines, or regulatory actions. For example, the AMCA Incident (as defined below under "Cybersecurity" in Item 1C) resulted in costs, pending and threatened litigation, and regulatory inquiries. For additional information about the AMCA Incident, see Note 15 Commitments and Contingencies to the Consolidated Financial Statements of Part III of the Annual Report.

## Modified: An inability to attract, retain, and develop experienced and qualified personnel, including personnel in key roles and critical positions, and increased personnel costs, could adversely affect the Company's business.

**Key changes:**

- Reworded sentence: "The loss of personnel in key roles and critical positions or the inability to attract, retain, and develop 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."
- Reworded sentence: "In addition, the success of the Company's early discovery, clinical, and commercial laboratories also depends on employing and retaining qualified and experienced professionals, including specialists, who perform laboratory research activities and testing services."
- Reworded sentence: "Changes to personnel in key roles and critical positions, and the ability to attract, develop, 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."

**Prior (2025):**

The loss of key management personnel or the inability to attract, retain, and develop 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, develop, 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.

## Modified: 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.

**Key changes:**

- Reworded sentence: "The commercial laboratory testing industry is subject to broad regulation in the U.S."

**Prior (2025):**

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.

**Current (2026):**

The commercial laboratory testing industry is subject to broad regulation in the U.S. and internationally. In the U.S. CLIA requires certification for virtually all clinical laboratories. Noncompliance with CLIA may result in suspension, revocation, or limitation of a laboratory's certificate, and the ability to bill government and other payers, as well as significant fines or criminal penalties. The Company is also subject to state laws that may impose additional requirements on laboratory operations and personnel. Outside the U.S., the Company's laboratories are subject to local laws and regulations, which vary by jurisdiction. Laws and regulations - many of which lack judicial interpretation - could be applied by regulatory or enforcement authorities in ways that adversely affect the Company's business. Potential sanctions include fines and loss of licenses or certifications. Additionally, future legislation may impose new compliance obligations that could be costly to implement.

## Modified: 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.

**Key changes:**

- Reworded sentence: "The Company enters into fixed-price and capped fee-for-service contracts, bearing financial risk if costs exceed estimates or pricing is insufficient."
- Reworded sentence: "Many BLS contracts may be terminated or reduced in scope, including for reasons such as safety issues, undesired product results, insufficient clinical trial or investigator enrollment, customer decisions to halt development, or failure to perform contractual obligations."

**Prior (2025):**

The Company has many contracts that are structured as fixed-price for fixed-contracted services or fee-for-service with a 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 BLS's contracts may be terminated or reduced in scope either immediately or upon notice. Cancellations may 33 33 33 Index Index 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 •BLS's failure to perform its duties properly under the contract. Although BLS's contracts typically entitle the Company to receive all fees earned up to the time of termination, and often also the costs of winding down the terminated projects, the loss, reduction in scope or delay of large or multiple contracts could materially adversely affect BLS.

**Current (2026):**

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

**Key changes:**

- Reworded sentence: "At December 31, 2025, the indebtedness on the Company's outstanding senior notes totaled $5.2 billion in aggregate principal, of which $500.0 million is payable within the next 12 months."

**Prior (2025):**

At December 31, 2024, indebtedness on the Company's outstanding senior notes totaled approximately $6.2 billion in aggregate principal, of which $1.0 billion is payable within the next 12 months. 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 34 34 34 Index Index 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.

**Current (2026):**

At December 31, 2025, the indebtedness on the Company's outstanding senior notes totaled $5.2 billion in aggregate principal, of which $500.0 million is payable within the next 12 months. The Company is also party to credit agreements relating to a $1.0 billion revolving credit facility subject to negative financial 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 could adversely affect its business. In particular, such indebtedness could increase the Company's vulnerability to sustained, adverse macro-economic downturns, limit financing flexibility, and limit its ability to pursue certain operational and strategic opportunities, including large acquisitions. Higher interest rates and changes in debt ratings could increase borrowing costs and reduce access to capital. Additional debt or credit arrangements may further restrict operations and liquidity. The Company may incur additional long-term debt, which could further increase its obligations and business restrictions. Additionally, major debt rating agencies regularly assess the Company's debt, and there is no assurance that the Company will be able to maintain its existing debt ratings and a failure to do so could raise funding costs and limit access to capital.

## Modified: Failure to comply with the regulations of pharmaceutical and medical device regulators, such as the FDA, the Medicines and Healthcare products Regulatory Agency in the U.K., the EU, the European Medicines Agency, the National Medical Products Administration in China, and the Pharmaceuticals and Medical Devices Agency in Japan, could result in fines, penalties, and sanctions against BLS and have a material adverse effect upon the Company.

**Key changes:**

- Reworded sentence: "The Company's preclinical and central laboratory operations must comply with applicable standards, including GLP, GCP, and for certain services, cGMP."

**Prior (2025):**

The operation of BLS's preclinical laboratory facilities and central laboratory 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 BLS'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 BLS must comply. If BLS does not comply, BLS 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 BLS 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 BLS, including suspension of its laboratory operations, which could have a material adverse effect upon the Company.

**Current (2026):**

The Company's preclinical and central laboratory operations must comply with applicable standards, including GLP, GCP, and for certain services, cGMP. These operations also involve the import, export, and use of medical devices, reagents, and biological products, which are subject to extensive local and international regulations. Failure to comply with these requirements could result in regulatory enforcement, civil, criminal, or administrative sanctions, including fines, suspension of laboratory operations, or restrictions on import/export activities. Maintaining compliance may also require significant resources and ongoing investment. Any enforcement action or disruption in laboratory operations could have a material adverse effect on the Company's business and results of operations.

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

**Key changes:**

- Reworded sentence: "BLS's preclinical services rely on healthy research animal populations."

**Prior (2025):**

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 BLS'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 BLS's reputation or have an adverse effect on BLS's financial condition, results of operations, and cash flows.

**Current (2026):**

BLS's preclinical services rely on healthy research animal populations. The presence of infectious or other diseases can compromise research quality, result in inventory loss, and pose risks to human or external animal populations. Such incidents may lead to reputational damage, operational disruption, and increased costs, adversely affecting the Company's financial condition and results of operations.

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

**Key changes:**

- Reworded sentence: "Consolidation of healthcare companies and providers, including pharmaceutical, biotechnology, and medical device companies, health systems, and physician practices through horizontal and vertical mergers, acquisitions, and partnerships, is increasing competition and giving some combined companies greater control over more aspects of healthcare, including increased bargaining power."

**Prior (2025):**

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 increasingly 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.

**Current (2026):**

Consolidation of healthcare companies and providers, including pharmaceutical, biotechnology, and medical device companies, health systems, and physician practices through horizontal and vertical mergers, acquisitions, and partnerships, is increasing competition and giving some combined companies greater control over more aspects of healthcare, including increased bargaining power. This competition and increased bargaining power may adversely affect the pricing and volume of the Company's services. In addition, as health systems acquire physician practices, maintaining strong relationships with hospital-based systems and integrated delivery networks is increasingly important to the Company's business. Dx's inability to retain its existing relationships with those physicians as they become part of healthcare systems and networks and/or create new relationships could impact its ability to successfully grow and maintain its business, which could adversely affect the Company's business.

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

**Key changes:**

- Reworded sentence: "BLS supports pharmaceutical, biotechnology, and medical device companies in navigating the regulatory approval and post-approval compliance requirements process."

**Prior (2025):**

BLS assists pharmaceutical, biotechnology, and medical device companies in navigating the regulatory approval process. Changes in government regulations, such as a relaxation in regulatory requirements or the introduction of simplified approval procedures or an increase in regulatory requirements that BLS may have difficulty satisfying or that may 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 BLS's customers may spend less, or reduce their growth in spending on R&D.

**Current (2026):**

BLS supports pharmaceutical, biotechnology, and medical device companies in navigating the regulatory approval and post-approval compliance requirements process. Changes in government regulations, whether easing or tightening requirements and changes in government operations, including staff reductions and reorganization efforts, could reduce the demand for BLS's services or make them less competitive. Additionally, efforts to control drug and device costs, or changes in insurer reimbursement practices, may lead customers to reduce R&D spending, which could adversely affect BLS's business.

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

**Key changes:**

- Reworded sentence: "The Company is subject to comprehensive regulation at the federal, state, and local levels in the U.S., as well as in other countries where it operates."

**Prior (2025):**

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, biopharmaceutical manufacturers, and others 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.

**Current (2026):**

The Company is subject to comprehensive regulation at the federal, state, and local levels in the U.S., as well as in other countries where it operates. Noncompliance with laws governing billing practices, financial relationships, and other healthcare-related activities could result in civil or criminal penalties, exclusion from Medicare and Medicaid, and restrictions on the use of the Company's laboratories. Although the Company believes it is in material compliance with applicable requirements, government authorities may take a contrary position. This includes potential interpretations of laws such as the Eliminating Kickbacks in Recovery Act, which currently lacks clarifying regulations or exceptions. Any enforcement action, regardless of outcome, could harm the Company's reputation and disrupt key business relationships.

## Modified: Operations may be disrupted and adversely impacted by events beyond the Company's control, including natural disasters, adverse weather, geopolitical events, public health crises, supply chain disruptions, and inaccessibility of natural resources.

**Key changes:**

- Reworded sentence: "Natural disasters (e.g., severe weather, fires, and earthquakes), geopolitical events (e.g., terrorism, war, and political instability), public health crises, criminal activity, supply chain disruptions, and other events beyond the Company's control could negatively affect the Company's operations."

**Prior (2025):**

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, inaccessibility of natural resources, and other disruptions or events beyond the Company's control could negatively affect the Company's operations. Any of these events may result in a temporary decline of testing volumes and other work in both segments. In addition, such events may temporarily interrupt the Company's ability to transport specimens, efficiently commence, continue, or complete its work on studies, utilize information technology systems, utilize certain laboratories, and/or 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.

**Current (2026):**

Natural disasters (e.g., severe weather, fires, and earthquakes), geopolitical events (e.g., terrorism, war, and political instability), public health crises, criminal activity, supply chain disruptions, and other events beyond the Company's control could negatively affect the Company's operations. These disruptions may temporarily reduce testing volumes, delay study progress, hinder specimen transport, limit access to laboratories and IT systems, and interrupt supply deliveries. They may also affect customer operations, further decreasing demand. Prolonged disruptions caused by such events, especially in key operational locations, could harm the Company's results of operations.

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

**Key changes:**

- Reworded sentence: "Government payers, including Medicare and Medicaid, and private insurers, such as MCOs, continue to implement measures to control healthcare costs, utilization, and delivery."

**Prior (2025):**

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 subject to certain delays in implementation and phase-in limits through 2027, 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. Medicare reimbursement for pathology services performed by Dx, which are paid 37 37 37 Index Index for under the PFS, 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.

**Current (2026):**

Government payers, including Medicare and Medicaid, and private insurers, such as MCOs, continue to implement measures to control healthcare costs, utilization, and delivery. These efforts include changes of reimbursement rates, coverage criteria, and administrative requirements. Under PAMA, phased reductions to Medicare reimbursement began in January 1, 2018, and are now frozen for 2026 but will resume in 2027, with capped reductions in 2027-2029, with potential for further reductions thereafter. Additional changes such as prior authorization requirements, diagnosis code edits, and other claims processing rules may also impact payment for diagnostic services. Reimbursement for pathology services performed by Dx under the Medicare PFS is subject to ongoing statutory and regulatory adjustments. Similar actions by commercial payers have historically led to lower payments, increased administrative costs, and reduced test utilization. Future changes in payer policies, laboratory benefit management programs, or insurance regulations could materially and adversely affect Dx's business, financial condition, and results of operations, which could have an adverse effect on the Company's business.

## Modified: Failure to conduct animal research in compliance with animal welfare laws and regulations could result in sanctions and/or remedies against BLS and have a material adverse effect on the Company.

**Key changes:**

- Reworded sentence: "BLS's preclinical research activities must comply with animal welfare laws in the jurisdictions where it operates, including the AWA and similar regulations in the U.K., the EU, and China."

**Prior (2025):**

The conduct of animal research at BLS'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 BLS conducts animal research, including the UK, EU, and China. BLS complies with licensing and registration requirement standards set by these laws and regulations in the jurisdictions in which it conducts animal research. If an enforcement agency determines that BLS'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 BLS that may include fines, suspension and/or revocation of animal research licenses, or confiscation of research animals.

**Current (2026):**

BLS's preclinical research activities must comply with animal welfare laws in the jurisdictions where it operates, including the AWA and similar regulations in the U.K., the EU, and China. These laws govern standards for housing, care, and oversight of research animals. Failure to meet regulatory requirements may result in fines, suspension or revocation of licenses, confiscation of animals, and reputational harm, any of which could have a material adverse effect on the Company's operations and financial results.

## Modified: Foreign currency exchange fluctuations could have an adverse effect on the Company's business.

**Key changes:**

- Reworded sentence: "The Company operates internationally and BLS derives a significant portion of its revenues from non-U.S."

**Prior (2025):**

The Company has business and operations outside the U.S., and BLS 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, BLS 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 BLS's results of operations, financial condition and cash flows.

**Current (2026):**

The Company operates internationally and BLS derives a significant portion of its revenues from non-U.S. operations. Since the Company's Consolidated Financial Statements are denominated in USD, fluctuations in foreign currency exchange rates may impact reported financial results, especially when costs and revenues are denominated in different currencies. These factors could significantly affect BLS's results of operations, financial condition, and cash flows, which could have an adverse effect on the Company's business. 25 25 25 TABLE OF CONTENTS TABLE OF CONTENTS

## Modified: The use of AI and machine learning tools in the Company's operations and the services of third-parties may introduce risks that could adversely affect the Company's business, financial condition, and reputation.

**Key changes:**

- Reworded sentence: "The Company and certain of its third-party vendors use AI and machine learning tools to enhance productivity and innovation, but these technologies also introduce risks."

**Prior (2025):**

The Company and its third parties leverage AI and machine learning tools to increase productivity and innovation. The Company also faces potential risks from the use of AI and machine learning tools. The Company, or its customers' sensitive, proprietary, or confidential information could be leaked, disclosed, or revealed as a result of or in connection with employees' or vendors' use of generative AI technologies. In addition, the Company may use AI outputs to inform certain decisions, and AI models may create incomplete, inaccurate, or otherwise flawed outputs, some of which may appear correct. Due to the potential flaws in the use of AI, the Company could make incorrect decisions, including decisions that could bias certain individuals or classes of individuals and adversely impact their rights. The rapid development of AI tools could render obsolete certain technologies or tools we currently use, or otherwise provide competitors with a technological edge. New or evolving legislation or regulations might impose restrictions on how AI and machine learning tools can be used, requiring the Company to adapt its tools or face various penalties for non-compliance, including potential disgorgement of data and associated capabilities. As a result, the Company could face adverse consequences, including exposure to reputational and competitive harm, customer loss, and legal liabilities. The AI tools may also be subject to additional, and as yet unidentified, security threats.

**Current (2026):**

The Company and certain of its third-party vendors use AI and machine learning tools to enhance productivity and innovation, but these technologies also introduce risks. Improper use may lead to data leaks of sensitive, proprietary, or confidential information, flawed outputs, biased decisions, or reputational harm. In addition, rapid advancements could render existing tools obsolete or give competitors an edge, emerging regulations may subject the Company to new restrictions or penalties, and AI systems may be vulnerable to new security threats. These risks could result in legal liabilities, customer loss, and reputational damage, each of which could have an adverse impact on the Company's business and operations.

## Modified: The Company's quarterly results of operations may vary significantly from quarter to quarter making it harder to predict future results.

**Key changes:**

- Reworded sentence: "The Company's results of operations may vary significantly from quarter to quarter and are influenced by factors over which the Company has little control, such as: •changes in the global economy, including the imposition of tariffs; •currency exchange rate fluctuations; •the commencement, completion, delay, or cancellation of large projects or contracts or groups of projects; •the progress of ongoing projects; •adverse weather, natural disasters, geopolitical events, public health crises, hostilities or acts of terrorism, acts of vandalism, disruption to supply chains, inaccessibility of natural resources, and other events beyond the Company's control; •the timing of and costs associated with completed acquisitions or other events; and •changes in the utilization mix of the Company's services."

**Prior (2025):**

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 global economy; •currency exchange rate fluctuations; •the commencement, completion, delay or cancellation of large projects or contracts or groups of projects; •the progress of ongoing projects; •adverse weather, natural disasters, geopolitical events, public health crises, hostilities or acts of terrorism, acts of vandalism, disruption to supply chains, inaccessibility of natural resources, and other events beyond the Company's control; •the timing of and costs 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.

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

**Key changes:**

- Reworded sentence: "The Company's international operations are subject to foreign laws and regulations that differ from those in the U.S."

**Prior (2025):**

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

**Current (2026):**

The Company's international operations are subject to foreign laws and regulations that differ from those in the U.S. Noncompliance may result in penalties, restrictions, and reputational harm. Risks include changes in reimbursement by foreign governments, export controls, trade regulations, tax policies, labor laws, and currency repatriation restrictions. Some jurisdictions may lack clear legal frameworks or strong enforcement of contractual and intellectual property rights. The Company may also face challenges related to regulatory approval, pricing, reimbursement, and marketing of its services abroad. Operating internationally can lead to unanticipated costs, including those related to compliance, staffing, collections, and managing local operations. In certain countries, success may depend on forming relationships with local partners, and failure to do so could adversely affect the Company's business and operations.

## Modified: 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.

**Key changes:**

- Reworded sentence: "The Company's diagnostic testing services are primarily billed to third parties, including MCOs, employer plans, and other health insurance providers."

**Prior (2025):**

Dx 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 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. Pursuant to PAMA, reimbursement rates for many clinical laboratory tests provided under Medicare were reduced from 2018 through 2020. Enforcement of PAMA was suspended each year from 2021 through 2025, but a long-term resolution through legislation has not yet been achieved, and the next round of PAMA reductions are currently on track to be implemented in 2026. Unless implementation of PAMA is further delayed or changed, additional reductions in reimbursements of $100.0 million are expected for 2026 from all payers affected by the CLFS. The Company's ability to attract and retain MCOs is critical given the impact of healthcare reform, changes in coverage and evolving value-based care and risk-based reimbursement delivery models (e.g., accountable care organizations (ACOs) and Independent Physician Associations (IPAs)). 30 30 30 Index Index 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 continues to increase, 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. 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. Payer policy changes in coverage, along with coding and billing changes, have had a negative impact over time on revenue, revenue per requisition, and margins and cash flows. In 2024, limited coding and billing changes were implemented. While limited changes are expected to be implemented in 2025, 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.

**Current (2026):**

The Company's diagnostic testing services are primarily billed to third parties, including MCOs, employer plans, and other health insurance providers. A shift toward a higher mix of government and MCO payers may adversely effect revenues due to lower reimbursement rates. Ongoing efforts by payers to reduce reimbursement, tighten payment policies, and control utilization are expected to continue. If the Company cannot offset these reductions through cost efficiencies, increased volume or new services, its revenues, profitability, and cash flows may be materially impacted. PAMA has already reduced Medicare reimbursement rates for many tests, and further reductions are expected, although rate reductions are frozen for 2026 and capped at 15% per year for 2027-2029. Delays and changes in coding, billing, and payer policies have historically impacted 22 22 22 TABLE OF CONTENTS TABLE OF CONTENTS revenue and margins, and similar disruptions may continue. Increasing patient cost-sharing and evolving value-based care models also pose collection challenges and may affect the Company's ability to attract and retain MCOs.

## Modified: Failure of the Company or its third-party service providers to comply with national security, privacy and data 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.

**Key changes:**

- Reworded sentence: "The Company and its third-party service providers are subject to numerous federal, state, and international laws governing national security, and the privacy and security of personal and health information."

**Prior (2025):**

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, litigation, or criminal sanctions. In the U.S., the Health Insurance Portability and Accountability Act of 1996, the U.S. Health Information Technology for Economic and Clinical Health (HITECH) Act, and their implementing privacy and security regulations (collectively, HIPAA) establish comprehensive standards with respect to the use and disclosure of protected health information (PHI), by covered entities as well as their "business associates" as defined in HIPAA, 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 provides 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 framework on a variety of subjects, including: 38 38 38 Index Index •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. In addition to the existing requirements under HIPAA, HHS issued an NPRM regarding revising the HIPAA Security Rule, which, if adopted, would impose increased requirements on regulated entities such as the Company. 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. To the extent applicable, newer laws like the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA), the Washington My Health My Data Act, and similar consumer privacy laws in other states, may impose additional obligations on the Company. 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. In addition, laws regulating artificial intelligence and machine learning, including the use of algorithms and automated processing, may impact the Company and lead to increases in the cost of compliance. Noncompliance with these laws could result in the imposition of fines, penalties, or orders to stop certain activities, and potentially expose the Company to actions 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) includes compliance obligations for subject companies and imposes penalties for noncompliance of up to the greater of €20 million or 4% of worldwide revenue for the most serious breaches of data protection obligations, and similar obligations exist under the UK GDPR. 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 other parts of Europe. The Company may be required to make changes to its business practices and to incur additional costs associated with compliance with these evolving and complex regulations.

**Current (2026):**

The Company and its third-party service providers are subject to numerous federal, state, and international laws governing national security, and the privacy and security of personal and health information. Noncompliance may result in fines, penalties, litigation, or criminal sanctions. In the U.S., HIPAA imposes detailed requirements on the use, disclosure, and safeguarding of PHI. HIPAA violations can lead to significant civil and criminal penalties. HIPAA also provides individuals with certain privacy rights regarding their PHI 28 28 28 TABLE OF CONTENTS TABLE OF CONTENTS and requires the Company to notify individuals about its privacy practices. The Company has implemented policies to comply with HIPAA, but evolving regulations - including a proposed rule to clarify the HIPAA Security Rule - may increase compliance obligations. State laws, such as the CCPA and the Washington My Health My Data Act, impose additional requirements that may exceed requirements under HIPAA and other federal standards. The Company must also comply with restrictions on international data transfers imposed through standards such as the DOJ's Data Security Program, and emerging laws regulating AI, algorithms, and automated processing, which may increase compliance costs. Internationally, the Company is subject to data protection laws, such as the EU GDPR and the U.K. GDPR, which impose strict requirements and significant penalties for noncompliance. Similar laws have been enacted in other regions where the Company operates, including Asia, Latin America, and other parts of Europe. Compliance with these complex and evolving regulations may require changes to the Company's business practices and result in increased operational costs. Failure to comply could materially and adversely affect the Company's business and reputation, result in the imposition of fines, penalties, or orders to stop certain activities, and potentially expose the Company to actions for the wrongful use or disclosure of personal information.

## Modified: Failure in the information technology systems of the Company or its vendors and other third-party service providers, or newly acquired businesses, or delays or failures in the development and implementation of new systems or updates or enhancements to existing systems, could adversely affect the Company's business.

**Key changes:**

- Reworded sentence: "The Company's operations rely on the continued performance and security of its information technology systems."

**Prior (2025):**

The Company's operations and customer relationships depend, in part, on the continued performance of its information technology systems. An information technology or process failure could impede the processing of data, delivery of data and services, customer orders, and day-to-day management of the business, and could result in the corruption or loss of data. Despite security measures and other precautions the Company has taken, including the development of contingency and disaster recovery plans, its information technology systems are potentially vulnerable to physical break-ins, fire, natural disaster, power loss, telecommunications failures, cybersecurity incidents and similar disruptions, and there may not be adequate protections, mitigation, backups, and/or redundant facilities available in the event these threats are realized. In addition, the Company may experience system failures, or interruptions, including cybersecurity incidents, 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 delays in the delivery of offerings to customers and other operations. 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.

**Current (2026):**

The Company's operations rely on the continued performance and security of its information technology systems. System failures, cybersecurity incidents, disruptions, or other issues affecting information technology systems could impair data processing, service delivery, billing, and customer communications. The Company also relies on third parties for critical services, including transportation, supplies, and data processing and expects them to comply with applicable laws and regulations, including environmental, health and safety, and privacy and data security laws. Failures by these providers, whether operational, legal, or cybersecurity-related, and issues affecting their information technology systems, could disrupt services, compromise personal or other confidential information, expose the Company to liability and could materially impact its business, even if the Company is not responsible for the underlying cause of any such failure or issue. In addition, the Company may be subject to regulatory, contractual, or other obligations arising from any such failure or issues. Despite contingency plans, risks remain, and a significant information technology system disruption could adversely affect the Company's reputation, operations, financial condition, and profitability.

## Modified: U.S. FDA regulation of LDTs and regulation by other countries of diagnostic offerings could have a material adverse effect on the Company's business.

**Key changes:**

- Reworded sentence: "The Company's diagnostic instruments, test kits, reagents, and point-of-care devices are subject to regulation by the FDA, which oversees their development, manufacturing, labeling, marketing, and performance."

**Prior (2025):**

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, 40 40 40 Index Index marketing, distribution, and surveillance of diagnostics, and it regularly inspects and reviews the manufacturing processes and performance of diagnostics. Dx's point-of-care testing devices are subject to regulation by the FDA. Historically, LDTs developed by high complexity clinical laboratories have been generally offered as services to health care providers under the CLIA regulatory framework administered by CMS, without the requirement for FDA clearance or approval. On April 29, 2024, the FDA released a final rule purporting to clarify its authority to regulate LDTs as medical devices under the federal Food, Drug, and Cosmetic Act, under which it will phase out its general enforcement discretion approach for LDTs under a four-year period subject to certain continuing enforcement discretion policies. The final rule was published on May 6, 2024, and became effective on July 5, 2024. In the absence of a successful legal challenge, the first phase of compliance obligations will begin on May 6, 2025. On May 29, 2024, the American Clinical Laboratory Association (ACLA) and its member company, HealthTrackRx, filed a lawsuit against the FDA in the United States District Court for the Eastern District of Texas, challenging the FDA's final rule. While the lawsuit may change the final rule or delay or prevent its enforcement, the issuance of the final rule presents an increased risk of FDA enforcement actions for laboratory tests offered by companies without FDA clearance or approval that do not fall within the ongoing enforcement discretion policies. However, the outcome and its ultimate impact on the Company's business remain difficult to predict at this time. Current FDA regulation of the Company's diagnostic offerings and the potential for future increased regulation of the Company's LDTs could result in increased costs and administrative and legal actions for noncompliance, including warning letters, fines, penalties, suspensions, recalls, injunctions, and other civil and criminal sanctions, and could impair the development and commercialization of new tests, which could have a material adverse effect upon the Company. Regulation of diagnostics offerings in jurisdictions outside the U.S. in which the Company operates may impact laboratory testing offered by the Company in both Dx and BLS. For example, the European Union In Vitro Diagnostics Regulation (Regulation (EU) 2017/746 (EU IVDR)) established 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 BLS's services, could impact BLS's ability to support trials, result in increased costs and administrative and legal actions, and have an adverse effect.

**Current (2026):**

The Company's diagnostic instruments, test kits, reagents, and point-of-care devices are subject to regulation by the FDA, which oversees their development, manufacturing, labeling, marketing, and performance. The FDA regularly inspects facilities and may take enforcement actions for noncompliance. Historically, LDTs offered by high-complexity laboratories have been regulated under CLIA without FDA oversight. However, on April 29, 2024, the FDA issued a final rule asserting authority to regulate LDTs as medical devices, initiating a four-year phase-out of its prior enforcement discretion. Legal challenges to the rule led to its recission, but if the FDA reissues a revised rule or otherwise seeks to reassert authority over LDTs, such actions could increase regulatory burdens and enforcement risks for LDTs not cleared or approved by the FDA. Noncompliance with FDA requirements may result in warning letters, fines, recalls, injunctions, and other civil or criminal penalties, potentially impacting the Company's ability to develop and commercialize new tests. Outside the U.S., the Company is subject to similar regulations, including the EU IVDR, which imposes classification, quality, and safety standards. Compliance with these evolving international frameworks may increase costs and affect the Company's ability to support clinical trials and offer laboratory services.

## Modified: BLS's revenues depend on R&D spending by companies in the pharmaceutical, biotechnology and medical device industries.

**Key changes:**

- Reworded sentence: "BLS's revenues are closely tied to R&D spending by pharmaceutical, biotechnology, and medical device companies, which may depend on access to capital and reimbursement from payers."

**Prior (2025):**

BLS'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 may be reliant on reimbursement for their products from government programs and commercial payers. Accordingly, economic factors and industry trends affecting BLS's customers in these industries may also affect BLS. 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, BLS could be materially adversely affected.

**Current (2026):**

BLS's revenues are closely tied to R&D spending by pharmaceutical, biotechnology, and medical device companies, which may depend on access to capital and reimbursement from payers. Economic conditions, industry trends, or funding constraints could lead to reduced or delayed R&D activity or outsourcing, materially impacting BLS's business and financial performance.

## Modified: Cybersecurity incidents and unauthorized access to the Company's or its customers' data could harm the Company's reputation and adversely affect its business.

**Key changes:**

- Reworded sentence: "The Company continues to face cybersecurity threats, including ransomware attempts, data breaches, and phishing and social engineering attempts targeting its systems and its employees, and those of third-party vendors."

**Prior (2025):**

The Company has previously experienced and expects to continue to experience attempts by unauthorized parties to compromise the Company's cybersecurity controls, like the 2018 ransomware attack. The Company has also experienced and expects to continue to experience similar attempts by threat actors to 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. Threat actors have a variety of attack methods, including without limitation, by 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. In addition, the increased use of AI by threat actors is enhancing the scale sophistication and effectiveness of their cyberattacks. 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, and other tactics. The Company has implemented a formal cybersecurity program; however, because the techniques used by threat actors to obtain unauthorized access, disable or degrade service, or sabotage systems continue to evolve (and often are not recognized until launched against a target), the Company may be unable to anticipate and/or implement appropriate controls needed to 36 36 36 Index Index protect against these evolving threats. In addition, as cyber threats continue to evolve including the use of AI by threat actors to compromise systems, the Company may be required to expend additional resources to continue to enhance the Company's cybersecurity measures or to investigate and remediate any cybersecurity vulnerabilities. The Company's remediation efforts may not be sufficient and could result in interruptions, delays, cessation of service, loss of data integrity, loss of confidentiality, and/or loss of data. This could also impact the cost and availability of cyber insurance to the Company. Cybersecurity incidents affecting 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 incidents 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 incidents could have a material adverse effect on the Company's business, regulatory compliance, financial condition, reputation, and/or results of operations. In addition, the Company faces increased cybersecurity risks due to the number of employees that continue to work remotely, which remains at levels higher than prior to the COVID-19 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.

**Current (2026):**

The Company continues to face cybersecurity threats, including ransomware attempts, data breaches, and phishing and social engineering attempts targeting its systems and its employees, and those of third-party vendors. Increasingly sophisticated methods, including the use of AI by threat actors, heighten these risks. The Company has implemented a formal cybersecurity program; however, threat actors' techniques continue to evolve and may not be identifiable until deployed, which could limit the Company's ability to prevent unauthorized access, data compromise, service disruption, or fraudulent activity. The Company may be unable to anticipate and/or implement appropriate controls needed to protect against these evolving threats or be required to expend additional resources to prepare for and respond to any cybersecurity vulnerabilities. Evolving threats may outpace defenses, requiring ongoing investment in security measures. Data and cybersecurity incidents, including those involving third parties, such as the AMCA Incident, could result in data loss, service disruption, reputational harm, litigation, regulatory penalties, and increased insurance costs. Remote work arrangements further elevate exposure to cyber risks. 27 27 27 TABLE OF CONTENTS TABLE OF CONTENTS

## Modified: Changes or disruption in services, supplies, or transportation provided by third parties have impacted, and could in the future materially impact, the Company's operations and business.

**Key changes:**

- Reworded sentence: "Despite having proprietary transport capabilities, the Company remains dependent on third parties for critical supplies and services, including transportation, laboratory materials, and specialized animal populations."

**Prior (2025):**

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, cybersecurity incidents, 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.

**Current (2026):**

Despite having proprietary transport capabilities, the Company remains dependent on third parties for critical supplies and services, including transportation, laboratory materials, and specialized animal populations. Disruptions in supply chains or access to transport - due to factors such as geopolitical instability, public health crises, natural disasters, or vendor noncompliance - have impacted, and could in the future materially impact, the Company's operations. Furthermore, 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 impact the Company's costs, testing volume and revenue.
