McKESSON CORPORATION
Business Segments
The Company operates its business in four reportable segments: U.S. Pharmaceutical, Prescription Technology Solutions (“RxTS”), Medical-Surgical Solutions, and International.
Our U.S. Pharmaceutical segment distributes branded, generic, specialty, biosimilar and over-the-counter (“OTC”) pharmaceutical drugs, and other healthcare-related products in the United States (“U.S.”). This segment also provides practice management, technology, clinical support, and business solutions to community-based oncology and other specialty practices. In addition, the segment sells financial, operational, and clinical solutions to pharmacies (retail, hospital, alternate sites) and provides consulting, outsourcing, technological, and other services.
Our RxTS segment helps solve medication access, affordability and adherence challenges for patients by working across healthcare to connect patients, pharmacies, providers, pharmacy benefit managers, health plans, and biopharma companies. RxTS serves our biopharma and life sciences partners, delivering innovative solutions that help people get the medicine they need to live healthier lives. RxTS offers technology services, which includes electronic prior authorization, prescription price transparency, benefit insight, and dispensing support services, in addition to third-party logistics and wholesale distribution support designed to benefit stakeholders.
Our Medical-Surgical Solutions segment provides medical-surgical supply distribution, logistics, and other services to healthcare providers, including physician offices, surgery centers, nursing homes, hospital reference labs, and home health care agencies. We offer more than 245,000 national brand medical-surgical products as well as McKesson’s own line of high-quality products through a network of distribution centers in the U.S.
Our International segment provides distribution and services to wholesale, institutional, and retail customers in Canada and Norway where we own, partner, or franchise with retail pharmacies, and support better, safer patient care by delivering vital medicines, supplies, and information technology solutions. During fiscal 2025, we completed the sale of Rexall and Well.ca businesses in Canada. Refer to Financial Note 2, “Business Acquisitions and Divestitures,”, to the consolidated financial statements included in this Annual Report for more information.
U.S. Pharmaceutical Segment:
Our U.S. Pharmaceutical segment provides distribution and logistics services for branded, generic, specialty, biosimilar, and OTC pharmaceutical drugs along with other healthcare-related products to customers. This business provides solutions and services to pharmacies, hospitals, oncology and other specialty practices, pharmaceutical manufacturers, biopharma partners, physicians, payors, and patients throughout the U.S. We also source generic pharmaceutical drugs through our ClarusONE Sourcing Services LLP joint venture with Walmart Inc. (“ClarusONE”).
Our U.S. Pharmaceutical segment operates and serves customers through a network of 27 distribution centers in the U.S., including two strategic redistribution centers. We invest in technology and other systems at all of our distribution centers to enhance safety, reliability, and product availability. For example, we offer McKesson Connect SM, an internet-based ordering system that provides item look-up and real-time inventory availability as well as ordering, purchasing, third-party reconciliation, and account management functionality. We make extensive use of technology as an enabler to ensure customers have the right products at the right time in the right place.
To maximize distribution efficiency and effectiveness, we follow the Six Sigma methodology, which is an analytical approach that emphasizes setting high-quality objectives, collecting data, and analyzing results to a fine degree in order to improve processes, reduce costs, and enhance service accuracy and safety. We provide solutions to our customers including supply management technology, world-class marketing programs, managed care, repackaging products, and services to help them meet their business and quality goals. We continue to implement information systems to help achieve greater consistency and accuracy both internally and for our customers, as well as make investments to increase capacity and automation.
We have four primary customer pharmaceutical distribution channels: (i) retail national accounts, which include national and regional retail chains, food and drug combinations, mail order pharmacies, and mass merchandisers, (ii) community pharmacies and health (formerly described as independent, small, and medium chain retail pharmacies), (iii) institutional healthcare providers such as hospitals, health systems, integrated delivery networks, and long-term care providers, and (iv) oncology, biopharma, and other specialty partners.

Ontada also partners with oncology providers and biopharma partners to perform real-world evidence studies, retrospective research, and to provide clinical data insights, advisory solutions and education opportunities.
When we discuss specialty products or services, we consider the following factors: diseases requiring complex treatment regimens such as cancer and rheumatoid arthritis; plasma and biologics products; ongoing clinical monitoring requirements, high-cost, special handling, storage, and delivery requirements and, in some cases, exclusive distribution arrangements. Our use of the term “specialty” may not be comparable to that used by other industry participants, including our competitors.

McKESSON CORPORATION
Prescription Technology Solutions Segment:
Our Prescription Technology Solutions segment works across healthcare to connect patients, pharmacies, providers, pharmacy benefit managers, health plans, and biopharma to deliver medication access solutions that support patients from first prescription fill to ongoing therapy, regardless of their insurance coverage. RxTS has connections with most electronic health record systems, over 50,000 pharmacies, approximately 950,000 providers, most pharmacy benefit managers and health plans, and has supported over 650 biopharma brands representing most therapeutic areas. Through its industry connections and ability to navigate the healthcare ecosystem, RxTS offers innovative solutions created to benefit healthcare stakeholders. Its comprehensive solution suites and technology services span across the entire patient journey, including medication access and affordability, prescription decision support, prescription price transparency, benefit insight and dispensing support services, as well as third-party logistics and wholesale distribution support, to help increase speed to therapy, reduce prescription abandonment, and support improved health outcomes for the patient. In the past year, RxTS helped patients save more than $10 billion on brand and specialty medications, helped to prevent an estimated 12 million prescriptions from being abandoned due to affordability challenges, and helped patients access their medicine more than 100 million times.
Medical-Surgical Solutions Segment:
Our Medical-Surgical Solutions segment delivers medical-supply distribution, logistics, biomedical maintenance, and other services to healthcare providers across the alternate-site spectrum. Our more than 340,000 customers include physician offices, surgery centers, post-acute care facilities, hospital reference labs, and home health agencies. We partner with manufacturers and channel partners to support our key target end-markets, including primary care, extended care, government, and other markets. We distribute medical-surgical supplies (such as gloves, needles, syringes, and wound care products), infusion pumps, laboratory equipment, and pharmaceuticals. Through a network of distribution centers in the U.S., we offer more than 245,000 products from national brand manufacturers and McKesson’s own brand of high-quality products. Through the right mix of products and services, we help improve efficiencies, profitability, and compliance. We also never lose focus on helping customers improve patient and business outcomes. We develop customized plans to address the product, operational, and clinical support needs of our customers, including inventory management, reducing administrative burdens, and training and educating clinical staff. We deliver for our customers, so they can deliver and care for their patients. In May 2025, the Company announced its intention to separate this segment into an independent company.
International Segment:
Our International segment includes operations in Canada and Norway. McKesson Canada is one of the largest pharmaceutical wholesale and retail distributors in Canada. The wholesale business delivers products to retail pharmacies, hospitals, long-term care centers, clinics and institutions in Canada through a national network of distribution centers and provides logistics and distribution services for manufacturers.
Beyond wholesale pharmaceutical logistics and distribution, McKesson Canada provides automation and technology solutions to its retail and hospital customers. Additionally, McKesson Canada provides comprehensive specialty health services to Canadians and provides biopharma services to manufacturers, including a national network of specialty pharmacies, personalized patient care and support programs, and INVIVA, Canada’s first and largest accredited network of private infusion clinics. McKesson Canada also owns and operates PDCI, Canada’s leading market access consultancy, supporting manufacturers as they introduce new products into the Canadian market.
The Canada retail business includes approximately 2,700 banner pharmacies under the IDA®, Guardian®, The Medicine Shoppe®, Remedy’sRx®, Proxim®, and Uniprix® banners. During fiscal 2025, we completed the previously announced transaction to sell our Rexall and Well.ca businesses. This divestiture is further described in Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report.
In July 2021, we announced our intention to exit our businesses in Europe. We divested the majority of our European businesses during fiscal 2022 and fiscal 2023. Our remaining operations in Europe provide distribution and services to wholesale and retail customers in Norway where we own, partner, or franchise with retail pharmacies. We continue to evaluate suitable exit alternatives for our retail and distribution businesses in Norway. Refer to Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report for additional information on our European divestitures.

McKESSON CORPORATION
Investments, Restructuring, Business Combinations, and Divestitures
We invest in new and existing distribution centers to increase scale and capacity, improve efficiency through automation and technology, and enhance regulatory compliance capabilities. Additionally, we invest in data and analytics to support our growth priorities, including artificial intelligence (“AI”). We are in the early stages of exploring potential AI capabilities and related data and analytics across our enterprise to improve productivity and efficiency, as well as enhance our products and services to better support patients, employees, and customers.
We have undertaken additional strategic initiatives in recent years designed to increase operational efficiencies, focus on our core healthcare businesses, execute our business strategy, and enhance our competitive position. These initiatives are detailed in Financial Note 2, “Business Acquisitions and Divestitures,” and Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” to the consolidated financial statements included in this Annual Report.
Competition
We operate in highly competitive environments in North America and Norway. In recent years, the healthcare industry has been subject to increasing consolidation. In the pharmaceutical distribution environment in which our U.S. Pharmaceutical and International segments operate, we face strong competition from international, national, regional, and local full-line, short-line, and specialty distributors, service merchandisers, self-warehousing chain drug stores, manufacturers engaged in direct distribution, third-party logistics companies, and large payer organizations. We consider our largest competitors in distribution, wholesaling, and logistics to be Cencora, Inc. and Cardinal Health, Inc.
Our RxTS business experiences substantial competition from many companies, including other biopharma services companies, software services firms, consulting firms, shared service vendors, and internet-based companies with technology applicable to the healthcare industry. Competition in this business varies in size from large to small companies, in geographical coverage, and in scope and breadth of products and services offered.
Our Medical-Surgical Solutions segment experiences competition from a wide range of national and regional medical supply and equipment distributors throughout the U.S.
In addition, we compete with other service providers and healthcare manufacturers, as well as other potential customers of our businesses, which may from time to time decide to develop, for their own internal needs, supply management capabilities that might otherwise be provided by our businesses. We believe that our scale and diversity of product and service offerings are our primary competitive advantages. In all areas, key competitive factors include price, quality of service, breadth of product lines, innovation, adoption of new and evolving technologies, and, in some cases, convenience to the customer.
Patents, Trademarks, Copyrights, and Licenses
McKesson and its subsidiaries hold patents, copyrights, trademarks, and trade secrets related to McKesson products and services. We pursue patent protection for our innovations and obtain copyright protection for our original works of authorship when such protection is advantageous. Through these efforts, we have developed a portfolio of patents and copyrights in the U.S. and worldwide. In addition, we have registered or applied to register certain trademarks and service marks in the U.S. and in foreign countries.
We believe that, in the aggregate, McKesson’s confidential information, patents, copyrights, trademarks, and intellectual property licenses are important to its operations and market position, but we do not consider any of our businesses to be dependent upon any one patent, copyright, trademark, or trade secret, or any family or families of the same. We cannot guarantee that our intellectual property portfolio will be sufficient to deter misappropriation, theft, or misuse of our technology, nor that we can successfully enjoin infringers. We periodically receive notices alleging that our products or services infringe on third-party patents and other intellectual property rights. These claims may result in McKesson entering settlement agreements, paying damages, discontinuing use or sale of accused products, or ceasing other activities. While the outcome of any litigation or dispute is inherently uncertain, we do not believe that the resolution of any of these infringement notices would have a material adverse impact on our results of operations.

McKESSON CORPORATION
We hold inbound licenses for certain intellectual property that is used internally, and in some cases, utilized in McKesson’s products or services. While in the future it may be necessary to seek or renew licenses relating to various aspects of our products and services, we believe, based upon past experience and industry practice, such licenses generally can be obtained on commercially reasonable terms. We believe our operations as well as our products and services are not materially dependent on any single license or other agreement with any third party.
Human Capital
Everything we do at McKesson begins with our employees, who bring our mission and purpose to life every day. As of March 31, 2025, we had approximately 45,000 employees worldwide, which includes 2,000 part-time employees. We had approximately 36,000 employees in the U.S., 5,000 employees in Canada, and 4,000 employees in the rest of the world. We also supplement our work-force with contractors and/or consultants for certain business projects, processes, and/or operations as demand requires.
Culture and Leadership: One of McKesson’s defining characteristics is our strong culture. We take pride in fostering a sense of belonging, finding meaning in our work, and caring for each other, our customers, and all those who depend on us. Our I 2 CARE values (Integrity, Inclusion, Customer-First, Accountability, Respect, Excellence) and ILEAD leadership behaviors (Inspire, Leverage, Execute, Advance, Develop) are at the core of our daily actions – from how we interact with each other and our customers, to how we make decisions, both big and small. We also offer all employees the opportunity to join employee resource groups (“ERGs”), which are voluntary, employee-led, company-sponsored networks that aim to make a positive impact on our employees’ lives. Each ERG is non-exclusive and open to every employee. Our ERGs focus on helping employees make authentic connections, celebrate and learn from each other, showcase leadership skills and find ways to nurture and support belonging and empowerment.
Investment in Employees: We are committed to investing in our employees, so that they, in turn, can focus on furthering our purpose of Advancing Health Outcomes for All®. We offer employees health and wellness benefits focused on physical, mental, and social well-being, savings programs to help prepare them for retirement and flexible work arrangements, and other offerings. We also offer employees regular training, coaching, and 360-degree assessments, and financial assistance programs for higher education opportunities.
We seek to attract and retain the best talent through competitive compensation and pay for performance, while prioritizing recognition of merit and compliance with laws. Our compensation philosophy is rooted in a fair and transparent program that regularly conducts benchmarking to assess market rates for talent, based on geography and other factors.
We solicit employee feedback through annual and mid-year employee opinion surveys, which assesses our employees’ levels of engagement, commitment and overall satisfaction using industry benchmarks, and then design action plans to improve those metrics. We also seek feedback on our people leaders through our annual manager quality survey, which is an opportunity for employees to help their managers grow professionally and build valuable leadership skills that help to promote a positive and productive workplace.
Health and Safety: Our security and safety teams employ systems designed to continually monitor our facilities and work environment to help identify and prevent or mitigate risks. This includes having procedures and investing in equipment for both physical and electronic security. Our employees receive specialized training related to their role, work setting, and equipment used in their work environment.
Government Regulation
We operate in many highly regulated environments and are subject to oversight by various federal, state, and local governmental entities in the U.S. and elsewhere. We incur significant expense and make large capital expenditures and investments to enable us to comply with laws and guidance promulgated by governmental entities.
The regulatory framework affecting our business and industry is continuously evolving and influenced by conditions such as public policy developments; shifts in governmental priorities, initiatives, and focus areas, including due to changes in federal, state, and local representation; and varied interpretations of laws and agency rulemaking conventions. These conditions create uncertainties for our business, and we are unable to predict the impact of future changes to the regulatory framework, or any prolonged uncertainty, on our operations and compliance costs.

McKESSON CORPORATION
See “Risk Factors” in Item 1A of Part I below for information regarding material risks associated with our compliance with governmental regulations.
Operational Licenses and Permits; Controlled Substances: We are subject to the operating and security standards of the U.S. Drug Enforcement Administration (“DEA”), the U.S. Food and Drug Administration (“FDA”), the U.S. Department of Health and Human Services (“HHS”), the Centers for Medicare & Medicaid Services (“CMS”), various state boards of pharmacy, state health departments, and comparable agencies in the U.S. and other countries. Certain of our businesses may be required to register for permits and/or licenses with governmental agencies, depending upon the type of operations and location of product development, manufacture, distribution, and sale. For example, we are required to hold valid DEA and state-level registrations and licenses, meet various security and operating standards, and comply with the Controlled Substances Act and its accompanying regulations governing the sale, marketing, packaging, holding, distribution, and disposal of controlled substances. We maintain extensive controlled substance monitoring and reporting programs at considerable expense in order to help us meet those standards.
Government Contracts: Our contracts with governmental entities typically are subject to procurement laws that include socio-economic, employment practices, environmental protection, recordkeeping and accounting, and other requirements. These statutory and regulatory requirements complicate our business and increase our compliance burden. We are subject to audits, investigations, and oversight proceedings about our compliance with contractual and legal requirements.
Healthcare Program Regulation: Federal, state, and local governmental entities in the U.S. and elsewhere continue to strengthen their position on, and scrutiny of, practices that may indicate fraud, waste, and abuse affecting government healthcare programs such as Medicare and Medicaid. Our relationships with pharmaceutical and medical-surgical product manufacturers, healthcare providers, and other companies and individuals, as well as our provision of products and services to governmental entities, subject our business to statutes, regulations, and government guidance that are intended to prevent fraud and abuse. Among other things, those laws: (1) prohibit persons from soliciting, offering, receiving, or paying any remuneration in order to induce the referral of an individual for, or to induce the ordering or purchasing of, items or services that are in any way paid for by Medicare, Medicaid, or other government healthcare programs; (2) prohibit physicians from referring certain “designated health services” to an entity with which they have a financial relationship, unless an exception applies; and (3) prohibit knowingly submitting, or causing to be submitted, a false or fraudulent claim for payment to the government; and (4) require certain entities to report and return an overpayment by Medicare or Medicaid within 60 days of identifying the overpayment.
Many of these healthcare fraud and abuse laws are vague or indefinite and are often subject to varied and evolving interpretations by courts, regulators, and enforcing agencies and, as such, may be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that could require us to make changes in our operations at added expense.
In the U.S., the Patient Protection and Affordable Care Act (“ACA”) significantly expanded health insurance coverage to uninsured Americans and changed the way healthcare is financed by both governmental and private payors. The implementation of the Inflation Reduction Act of 2022 (“IRA”) has begun to change benefit design and how Medicare pays for drugs, which are all intended to reduce the price of drugs. Three central features of the IRA have authorized the government to negotiate drug prices for certain Parts B and D drugs over time, establish an inflation rebate program, and cap patient cost sharing under Medicare Part D.
Provincial governments in Canada that provide partial funding for the purchase of pharmaceuticals and independently regulate the sale and reimbursement of drugs have sought to reduce the costs of publicly funded health programs. For example, provincial governments have taken steps to reduce consumer prices for generic pharmaceuticals and, in some provinces, change professional allowances paid to pharmacists by generic drug manufacturers.
McKesson continues to advocate for policies that would improve drug cost transparency under a patient's drug plan to better inform prescribing decisions, and also address access to care, affordability, and treatment regimen adherence, all designed to improve clinical outcomes and reduce the health spending burden.
FDA Regulation and Supply Chain Integrity: In the U.S., the FDA is the principal federal authority that regulates the safety, efficacy, quality, testing, premarket approval, manufacture, labeling, storage, distribution, and post-market surveillance of healthcare products, such as drugs and medical devices, foods, and cosmetics.

McKESSON CORPORATION
Federal and state laws regulate the pharmaceutical drug supply chain in order to prevent the distribution of counterfeit, stolen, contaminated, or otherwise harmful prescription drugs in interstate commerce. At the federal level, the Drug Supply Chain Security Act (“DSCSA”), among other things, requires standardized, unit-level traceability of pharmaceutical products along the entire drug supply chain and requires all trading partners to cooperate in an electronic, interoperable prescription drug traceability system. In October 2024, the FDA extended the compliance deadlines for the DSCSA interoperable unit-level traceability requirements to May 27, 2025, for manufacturers, August 27, 2025 for distributors, and November 27, 2025 for dispensers. The FDA stated that these extensions apply to trading partners who meet certain conditions. The Company believes its businesses are eligible for the extensions. The DSCSA also sets forth national standards for the licensure of wholesale drug distributors and third-party logistic providers and other requirements applicable to these entities and the FDA has issued a proposed rule with respect to these requirements. These federal and state regulatory requirements have increased, and may further increase, our compliance burden and distribution costs.
Additionally, federal and state governments may adopt other laws intended to protect the integrity of the supply chain, and those laws could affect our distribution business. For example, the Federal Trade Commission (“FTC”) and HHS issued a request for public comment in 2024 on how the practices of pharmaceutical wholesalers and group purchasing organizations impact generic drug shortages. Various industry stakeholders responded to this request, but no further action has been taken by the FTC or HHS.
Cybersecurity, Data Security, Privacy, and AI: We are subject to many cybersecurity, privacy, and data protection laws that change frequently and have requirements that vary from jurisdiction to jurisdiction. Our efforts to comply with these laws complicate our operations and add to our costs. We are subject to significant compliance obligations under privacy laws such as the Health Insurance Portability and Accountability Act of 1996, the General Data Protection Regulation in the European Union, the Personal Information Protection and Electronic Documents Act in Canada, and an expanding list of comprehensive state privacy laws in the U.S. Some privacy laws may prohibit the transfer of personal information to certain other jurisdictions or otherwise limit our use and disclosure of data. Many of these laws also require us to provide access or other data rights (modification, deletion, portability, etc.) to consumers’ and patients’ individual personal data records within specified periods of time. Cybersecurity laws such as the federal Cyber Incident Reporting for Critical Infrastructure Act of 2022, proposed changes to the Federal Acquisition Regulation, and SEC reporting requirements may require us to provide notifications of certain cybersecurity incidents within short timeframes. Regulations and guidance targeting critical infrastructure entities, including McKesson, continue to be a focus of regulators. We are subject to privacy and data protection compliance audits or investigations by various governmental agencies. There is also an emerging trend of governmental entities proposing and providing regulatory guidance related to AI, including generative AI. If we or our third-party providers are restricted from using AI as a result of any regulatory views, laws or other measures, it could impact our operations, increase our compliance expense and burden, and cause us to incur costs to replace or modify our use of AI.
Environmental Regulation: We are subject to various federal, state, local, and foreign laws concerning the environment, including laws addressing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, and the cleanup of contaminated sites, as well as laws governing the operation of radiation-emitting equipment at U.S. Oncology Network practices.
We sold our chemical distribution operations in 1987 and retained responsibility for certain environmental obligations. Agreements with the U.S. Environmental Protection Agency and certain states have required and may require environmental assessments and cleanups at several closed sites. These matters are described further in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual Report.
Climate Change Regulation: Governments in the U.S. and abroad have adopted or are considering new or expanded policies and laws to address climate change. Such policies and laws may necessitate reductions in greenhouse gas (“GHG”) emissions; mandate that companies implement processes and controls to monitor and disclose climate-related matters; and impose additional taxes or offset charges on specified energy sources, among other requirements. Compliance with climate-related policies and laws may be further complicated by disparate regulatory approaches in various jurisdictions. Methodologies for reporting climate-related information may change and previously reported information may be retroactively adjusted, if required. New or expanded climate-related policies and laws could impose costs on us, including capital expenditures to develop data gathering and reporting systems, third-party attestations, and additional GHG reduction measures. Until the timing and extent of climate-related policies and laws are clarified, including due to legal challenges, we cannot predict their potential effect on our capital expenditures, results of operations, or competitive position.

McKESSON CORPORATION
Antitrust Laws: Antitrust and competition laws in the U.S. and elsewhere prohibit types of conduct deemed to be anti-competitive. Antitrust enforcement in the healthcare industry remains a focus of the FTC and the U.S. Department of Justice. Some of our strategic transactions may require review by competition regulators, with inherent delays. Violations of the antitrust laws can result in sanctions and other adverse actions, including criminal and civil penalties. Private plaintiffs also may bring civil lawsuits for alleged antitrust law violations, including claims for treble damages. These laws contribute to our compliance efforts and expense, and their enforcement might materially adversely affect our operations and growth strategy.
Other Information about the Business
Customers: During fiscal 2025, sales to our ten largest customers, including group purchasing organizations (“GPOs”) accounted for approximately 72% of our total consolidated revenues. Sales to our largest customer, CVS Health Corporation (“CVS”), accounted for approximately 24% of our total consolidated revenues in fiscal 2025. In fiscal 2023, we extended our pharmaceutical distribution partnership with CVS to June 2027. Our ten largest customers comprised approximately 48%, and CVS was approximately 23% of our total trade accounts receivable at March 31, 2025. We also have agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies, and other healthcare providers, as well as with government entities and agencies. The accounts receivable balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. Substantially all of these revenues and accounts receivable are included in our U.S. Pharmaceutical segment.
Suppliers: We obtain pharmaceutical and other products from manufacturers and our largest supplier accounted for 11% of our total purchases in fiscal 2025. The loss of a supplier could adversely affect our business if alternate sources of supply are unavailable. We believe that our relationships with our suppliers are generally sound. The ten largest suppliers in fiscal 2025 accounted for approximately 69% of our total purchases.
Some of our distribution arrangements with manufacturers provide us consideration based on a percentage of our purchases. In addition, we have certain distribution arrangements with pharmaceutical manufacturers that include an inflation-based consideration component whereby we benefit when the manufacturers increase their prices as we sell our existing inventory at the new higher prices. For these manufacturers, a reduction in the frequency and magnitude of price increases, as well as restrictions in the amount of inventory available to us, could have an adverse impact on our gross profit margin.
Research and Development: Research and development expenses were $91 million, $77 million, and $89 million for the years ended March 31, 2025, 2024, and 2023, respectively.
Financial Information About Foreign and Domestic Operations: Certain financial information relating to foreign and domestic operations is discussed in Financial Note 20, “Segments of Business,” to the consolidated financial statements included in this Annual Report as well as in “Foreign Operations” in Item 7 of Part II of this Annual Report. See “Risk Factors” in Item 1A of Part I below for information regarding risks associated with our foreign operations.

Litigation and Regulatory Risks | 13
Company and Operational Risks | 16
Industry and Economic Risks | 20
General Risks | 23

The discussion below identifies certain representative risks that might cause our actual business results to materially differ from our estimates. It is not practical to identify or describe all risks and uncertainties that might materially impact our business operations, reputation, financial position, or results of operations. Our business could be materially affected by risks that we have not yet identified or that we currently consider to be immaterial. This is not a complete discussion of all potential risks and uncertainties.
Litigation and Regulatory Risks
We experience costly and disruptive legal disputes.
We are routinely named as a defendant in litigation or regulatory proceedings and other legal disputes, which may include asserted class action litigation, such as those described in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual Report. Regulatory proceedings involve allegations such as false claims, healthcare fraud and abuse, and antitrust violations. Civil litigation proceedings involve commercial, employment, environmental, intellectual property, tort, and other claims. Despite valid defenses that we assert, legal disputes are often costly, time-consuming, distracting to management, and disruptive to normal business operations. The uncertainty and expense associated with unresolved legal disputes might harm our business and reputation even if the matter ultimately is favorably resolved. The outcome of legal disputes is difficult to predict, and outcomes may occur that we believe are not justified by the evidence or existing law. Outcomes include monetary damages, penalties and fines, and injunctive or other relief that requires us to change our business operations and incur significant expense. Accordingly, legal disputes might have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.

McKESSON CORPORATION
We experience losses not covered by insurance or indemnification.
Our business exposes us to risks that are inherent in the distribution, manufacturing, dispensing, and administration of pharmaceuticals and medical-surgical supplies, the provision of ancillary services, the conduct of our payer businesses, practice support services, and the provision of products that assist clinical decision-making and relate to patient medical histories and treatment plans. For example, pharmacy operations are exposed to risks such as improper filling of prescriptions, mislabeling of prescriptions, inadequacy of warnings, unintentional distribution of counterfeit drugs, and expiration of drugs. Although we seek to maintain adequate insurance coverage, such as property insurance for inventory and professional and general liability insurance, coverages on acceptable terms might be unavailable, or coverages might not cover our losses. We generally seek to limit our contractual exposure, but limitations of liability or indemnity provisions in our contracts may not be enforceable or adequately protect us from liability. Uninsured or non-indemnified losses might have a materially adverse impact on our business operations and our financial position or results of operations.
We experience costly legal disputes, government actions, and adverse publicity regarding our role in distributing controlled substances such as opioids.
The Company is a defendant in many litigation matters alleging claims related to the distribution of controlled substances (opioids), as described in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements in this Annual Report. We are sometimes named as a defendant in similar, new cases. The plaintiffs in those cases include governmental entities (such as states, provinces, counties, and municipalities) as well as businesses, groups, and individuals. The cases allege violations of controlled substance laws and other laws, and they make common law claims such as negligence and public nuisance. Many of these cases raise novel theories of liability and can have unexpected outcomes that we believe are not justified by evidence or existing law. Legal proceedings such as these often involve significant expense, management time and distraction, and risk of loss that can be difficult to predict or quantify. It is not uncommon for claims to be resolved over many years. Outcomes include monetary damages, penalties and fines, and injunctive or other relief that requires us to change our business operations and incur significant expense. Although the Company has valid defenses and is vigorously defending itself, some proceedings have been, and others may be, resolved by negotiated outcome. For example, we are subject to consent decrees issued by state courts that govern our distribution of controlled substances. Not all proceedings, however, are resolved by settlement. Our reputation has been and may continue to be impacted by publicity regarding opioids litigation and related allegations. An adverse outcome of any such legal proceedings might have a materially adverse impact on our business operations and our financial position or results of operations.
We experience increased costs to distribute controlled substances such as opioids.
Legislative, regulatory, or industry measures related to the distribution of controlled substances such as prescription opioids could affect our business in ways that we may not be able to predict. For example, some states have passed legislation that could require us to pay taxes or assessments on the distribution of opioid medications in those states and other states have considered similar legislation. Liabilities for taxes or assessments or other costs of compliance under any such laws might have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.
We are subject to extensive, complex, and challenging healthcare, environmental, and other laws.
As described in “Government Regulation” in Item 1 of Part I above, our industry is highly regulated, and further regulation of our distribution businesses, technology products, and services could impose increased costs, negatively impact our profit margins and the profit margins of our customers, delay the introduction or implementation of our new products, or otherwise negatively impact our business and expose the Company to litigation and regulatory investigations. We incur cleanup costs under environmental laws and may incur additional costs under environmental laws. Additionally, we are subject to various routine and ad hoc inspections and requests for information by governmental agencies to determine compliance with various statutes and regulations. Any noncompliance by us with applicable laws, or the failure to maintain, renew, or obtain necessary permits and licenses, could lead to enforcement actions or litigation and might have a materially adverse impact on our business operations and our financial position or results of operations.

We are subject to extensive and frequently changing laws relating to healthcare fraud, waste, and abuse.
As described in “Government Regulation” in Item 1 of Part I above, federal, state, and local governmental entities in the U.S. and elsewhere continue to strengthen their position on, and scrutiny of, practices that may indicate fraud, waste, and abuse affecting government healthcare programs such as Medicare and Medicaid. Those laws may be interpreted or applied in a manner that could require us to make changes in our operations at added expense. Alleged failures to comply with those laws, including the federal Anti-Kickback Statute, expose us to federal or state government investigations or qui tam actions, and to liability for damages and civil and criminal penalties. Such failures might result in the loss of licenses or our ability to participate in Medicare, Medicaid, or other federal and state healthcare programs, or pursue government contracts. These sanctions might have a materially adverse impact on our business operations and our financial position or results of operations.
We might lose our ability to purchase, store, or distribute pharmaceuticals, including controlled substances, and medical products.
As described in “Government Regulation” in Item 1 of Part I above, we are subject to the operating, quality, regulatory, and security requirements of the DEA, the FDA, various state boards of pharmacy, state health departments, CMS, and other agencies. Noncompliance with these requirements can result in inspectional observations, warning letters, product recalls, withdrawals or other market action, fines, seizures, injunctions, and other administrative, civil, and criminal enforcement actions. Noncompliance, enforcement actions or adverse decisions by regulators, or the inability to obtain, maintain, or renew permits, licenses, or other regulatory approvals needed for the operation of our businesses might have a materially adverse impact on our reputation, our business operations and our financial position or results of operations.
Privacy, cybersecurity, data protection, and AI laws increase our compliance burden.
As described in “Government Regulation” in Item 1 of Part I above, we are subject to a variety of privacy, cybersecurity, data protection, and AI laws that change frequently and have requirements that vary from jurisdiction to jurisdiction. Failure to comply with these laws subjects us to potential regulatory enforcement activity, fines, private litigation including class actions, reputational impacts, and other costs. We also have contractual obligations that might be breached if we fail to comply with privacy and data security laws. The use of AI solutions by our employees or third parties on which we rely could also lead to the misuse of data or public disclosure of confidential information (including personal data or proprietary information) in contravention of our internal policies, applicable laws, contractual requirements, or third-party intellectual property rights. Our efforts to comply with privacy, data security, and AI laws complicate our operations and add to our costs. A significant cybersecurity and/or privacy breach or failure to comply with privacy and data security laws, by us or by external service providers, vendors, or other third parties with which we do business, might have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.
Anti-bribery and anti-corruption laws increase our compliance burden.
We are subject to laws prohibiting improper payments and bribery, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, and similar regulations in other jurisdictions. Our failure to comply with these laws might subject us to civil and criminal penalties that might have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.

Company and Operational Risks
We might record significant charges from impairment to goodwill, intangibles, and other long-lived assets.
We are required under U.S. Generally Accepted Accounting Principles (“GAAP”) to test our goodwill for impairment annually or more frequently if indicators for potential impairment exist. Indicators that are considered include significant changes in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, or a significant decline in the Company’s stock price and/or market capitalization for a sustained period of time. In addition, we periodically review our intangible and other long-lived assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Factors that may be considered a change in circumstances indicating that the carrying value of our intangible and other long-lived assets may not be recoverable include slower growth rates, the loss of a significant customer, burdensome new laws or other adverse legal developments, or divestiture of a business or asset for less than its carrying value. There are inherent uncertainties in management’s estimates, judgments, and assumptions used in assessing recoverability of goodwill, intangibles, and other long-lived assets. Any material changes in key assumptions, including failure to meet business plans, negative changes in government reimbursement rates, a deterioration in the U.S. and global financial markets, an increase in interest rates, an increase in inflation, or an increase in the cost of equity financing by market participants within the industry, or other unanticipated events and circumstances, may decrease the projected cash flows or increase the discount rates and could potentially result in an impairment charge. We have in the past recorded, and may be required to record, a significant charge to earnings in our consolidated financial statements during the period in which any impairment of our goodwill or intangible and other long-lived assets is determined, which might have a materially adverse impact on our business operations and our financial position or results of operations. See Financial Note 10, “Goodwill and Intangible Assets,” for descriptions of impairments of goodwill or intangible or other long-lived assets in recent periods.
We experience cybersecurity incidents that might significantly compromise our technology systems or might result in material data breaches.
We, our external service providers, vendors, and other third parties with which we do business, use technology and systems to perform our business operations, such as the secure electronic transmission, processing, storage, and hosting of sensitive information, including protected health information and other types of personal information, confidential financial information, proprietary information, and other sensitive information relating to our customers, company, and workforce. Despite our physical, technical, and administrative security measures as well as third party risk management processes as discussed in “Cybersecurity” in Item 1C of Part I below, technology systems and operations of the Company and third parties, including our external service providers and vendors, with which we do business, have experienced cybersecurity incidents and are subject to future cyberattacks and cybersecurity incidents. Companies in the healthcare industry are increasingly targeted for cyberattacks. Cybersecurity incidents include unauthorized occurrences on or conducted through our or our third parties’ information systems, such as tampering, malware insertion, ransomware attacks, or other system integrity events. The risk and efficacy of cyberattacks increases from time to time due to a variety of internal and external factors, including, but not limited to, the adoption of sophisticated and rapidly evolving techniques, such as adversarial AI, and during political or military unrest. Our adoption of AI also may create new attack surfaces or methods and generally increase cybersecurity and data protection risks and costs. A cybersecurity incident might involve a material data breach or other material impact to the confidentiality, integrity, availability, and operations of our technology systems or data, which might result in harm to patients, consumers, or employees; litigation or regulatory action; disruption of our business operations; loss of customers or revenue; cash flow impacts; and increased expense. Additionally, it may take considerable time for us to investigate and evaluate the full impact of incidents, particularly for sophisticated attacks. These factors may inhibit our ability to provide prompt, full, and reliable information about the incident to our customers, regulators, and the public. Any cybersecurity incident might have a materially adverse impact on our business, our operations, our reputation, and our financial position or results of operations.
We experience significant problems with information systems or networks.
We rely on sophisticated information systems and networks to perform our business operations, such as to obtain, rapidly process, analyze, and manage data that facilitate the purchase and distribution of thousands of inventory items from distribution centers. We provide remote services that involve hosting customer data and operating software on our own or third-party systems. Our customers rely on their ability to access and use these systems, and their data, as needed, and our ability to compete effectively is increasingly dependent on access to, and interpretation of, data. Data quality impacts customer ordering, order fulfillment and higher order processing. If we fail to effectively implement and maintain data governance structures across our businesses, to effectively interpret and utilize such data, or protect the integrity of such data, including systems

McKESSON CORPORATION
powered by or incorporating AI and machine learning, our operations could be impacted, and we may be at a competitive disadvantage. Our networks and hosting systems are also vulnerable to interruption or damage from sources beyond our control. When those information systems or networks are disrupted, or if the timely delivery of medical care or other customer business requirements are impaired, we experience injury to patients or consumers, litigation or regulatory action, disruption of our business operations, loss of customers or revenue, cash flow impacts, and increased expense. In addition, hardware, software, and other applications and updates procured from third parties may contain defects that have, or may in the future, unexpectedly restrict access to or interfere with the proper operations of our information systems and hardware. Any such problems might have a materially adverse impact on our business, our reputation, and our financial position or results of operations.
Our technology products or services might not conform to specifications or perform as we intend.
We sell and provide services involving complex software and technology that may contain errors, especially when first introduced to market. Healthcare professionals delivering patient care tend to have heightened sensitivity to system and software errors. If our software and technology services are alleged to have contributed to faulty clinical decisions, compromised continuity of patient care, or injury to patients, we might be subject to regulatory scrutiny or, claims by users of our software or services and/or their patients. Errors or failures might damage our reputation and negatively affect future sales. A failure of a system or software to conform to specifications might constitute a breach of warranty that could result in repair costs, contract termination, refunds, or claims for damages. These risks can be heightened upon the adoption of new technologies, including AI, and may introduce new or expanded risks, such as data inaccuracy, unreliability, or bias. Any of these types of errors or failures might have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.
Pharmaceutical and medical products that we distribute might not conform to specifications or perform as intended.
We distribute pharmaceutical, medical, and other FDA-regulated products manufactured by third parties and by our private label businesses, including medications that may be temperature sensitive or have limited shelf lives. Our systems and procedures are designed to maintain the safety and efficacy of the products throughout the sourcing and distribution process. Issues affecting product safety or efficacy can arise from manufacturing, storing, distributing, dispensing or using products, and can result in adverse consequences such as safety alerts, seizures, bans, recalls, withdrawals or other market action, suspensions, and other regulatory actions and sanctions, civil lawsuits, increased costs, disruptions, delays, and reputational damage. Any of these types of issues or results might have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.
We might not realize expected benefits from business process initiatives.
From time to time, we implement restructuring, cost reduction, or other business process initiatives that result in significant charges and expenses. These initiatives might fail to achieve our desired objectives or have unintended consequences such as distraction of our management and employees, business disruption, attrition beyond any planned reduction in workforce, inability to attract or retain key personnel and reduced employee productivity. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be unable to successfully complete or integrate acquisitions or other strategic transactions.
Our growth strategy includes consummating acquisitions or other strategic transactions that either expand or complement our business. To fund these strategic transactions, we may require financing that may not be available on acceptable terms. We may not receive governmental approvals needed to complete proposed transactions, or such approvals may be subject to delays or conditions that reduce transaction benefits. Achieving the desired outcomes of these strategic transactions involves significant risks including: diverting management’s attention from other business operations; challenges with assimilating the acquired businesses, such as integration of operations, systems, and technologies; failure or delay in realizing operating synergies; difficulty retaining key acquired company personnel; unanticipated accounting or financial systems issues with the acquired business, which might affect our internal controls over financial reporting; disputes with the sellers of acquired businesses; unanticipated compliance issues in the acquired business; unknown or unanticipated cybersecurity issues; challenges retaining customers of the acquired business; unanticipated expenses or charges to earnings, including depreciation and amortization or potential impairment charges; and risks of known and unknown assumed liabilities in the acquired business. These risks at times have adversely affected, and could in the future adversely affect, our ability to achieve the anticipated benefits of an acquisition, and might have a materially adverse impact on our business operations and our financial position or results of operations.

McKESSON CORPORATION
From time to time we are adversely impacted by delays or other difficulties with divestitures.
When we decide to sell or otherwise divest assets or a business, we may encounter difficulty in finding buyers or exit strategies on acceptable terms or in a timely manner, which could delay the achievement of our strategic objectives. After the disposition, we might experience greater dissynergies than expected, and the impact of the divestiture on our revenue or profit might be larger than we expected. We might have difficulties with pre-closing conditions such as governmental approvals, which could delay or prevent the divestiture. We might have financial exposure in a divested business, such as through minority equity ownership, financial or performance guarantees, indemnities, or other obligations, such that conditions outside of our control might negate the expected benefits of the disposition. Any of these risks could adversely affect our ability to achieve the anticipated benefits of a divestiture and might have a materially adverse impact on our business operations and our financial position or results of operations.
We might not realize the expected tax treatment from our split-off of Change Healthcare.
On March 10, 2020, the Company completed a separation of its interest in Change Healthcare LLC (“Change Healthcare JV”). The divestiture was effected through the split-off of PF2 SpinCo, Inc. (“SpinCo”), a wholly owned subsidiary of the Company that held all of the Company’s interest in the Change Healthcare JV, to certain of the Company’s stockholders through an exchange offer (the “Exchange Offer”), followed by a merger of SpinCo with and into Change Healthcare Inc. (“Change”), with Change surviving the merger (the “Merger” and, together with the Exchange Offer, the “Transactions”). The Company received an opinion from outside legal counsel to the effect that the Transactions qualified as generally tax-free transactions to the Company and its shareholders for U.S. federal income tax purposes. An opinion of legal counsel is not binding on the Internal Revenue Service (the “IRS”) or the courts, and the IRS or the courts may not agree with the intended tax-free treatment of the Transactions. In addition, the opinion could not be relied upon if certain assumptions, representations, and undertakings upon which the opinion was based are materially inaccurate or incomplete, or are violated in any material respect. If the intended tax-free treatment of the Transactions is not sustained, the Company and its stockholders who participated in the Transactions may be required to pay substantial U.S. federal income taxes. In connection with the Transactions, the Company, SpinCo, Change, and the Change Healthcare JV entered into the Tax Matters Agreement, which governs their respective rights, responsibilities, and obligations with respect to tax liabilities and benefits, tax attributes, tax contests, and other tax sharing regarding U.S. federal, state, and local, and non-U.S. taxes, other tax matters, and related tax returns. Under the Tax Matters Agreement, Change is required to indemnify the Company if the Transactions become taxable as a result of certain actions by Change or SpinCo, or as a result of certain changes in ownership of the stock of Change after the Merger. If Change does not honor its obligations to indemnify the Company, or if the Transactions fail to qualify for the intended tax-free treatment for reasons not related to a disqualifying action by Change or SpinCo, the resulting tax to the Company could have a significant adverse effect on our financial position or results of operations.

McKESSON CORPORATION
We might be adversely impacted by outsourcing or similar third-party relationships.
We rely on third parties to perform certain business and administrative functions for us. We might not adequately develop, implement, and monitor these outsourced service providers, and we might not realize expected cost savings or other benefits. Third-party service providers experience cybersecurity incidents and other disruptions and can fail to perform their obligations due to various causes, which might cause us to incur operational difficulties, additional compliance requirements, or increased costs related to outsourced services. For example, our ability to use outsourcing resources in certain jurisdictions might be limited by legislative action or customer contracts, with the result that the work must be performed at greater expense or we may be subject to sanctions for non-compliance. Any of these risks might have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.
We may be unsuccessful in achieving our strategic growth objectives.
Our business strategy as a diversified healthcare services company includes investing to build an integrated oncology and specialty care platform and expand our biopharma services business. Our ability to grow those businesses will depend on our: hiring and retaining talented individuals with necessary knowledge and skills; acquiring, developing, and implementing new technologies and capabilities, including AI; forming and expanding business relationships; and successfully competing against providers of similar services. New technologies, such as AI, may not result in the benefits we anticipate, may not enable us to maintain a competitive advantage, and may require us to expend significant resources. We have increased, and expect to continue to increase, our use of AI technology. The AI technologies we employ may become obsolete earlier than planned or we may be unsuccessful at realizing the benefits of these investments. Additionally, some of our historical competitors and a growing number of new competitive entrants have more experience than we do in enabling technologies such as data analytics, machine learning, or AI. We may not achieve our desired return on our investments through our growth strategies. If we fail to achieve acceptable sales and profitability in our strategic growth areas, it might have a materially adverse impact on our business prospects and our financial position or results of operations.
We are impacted by customer purchase reductions, contract non-renewals, payment defaults, and bankruptcies.
Some of our customers from time to time reduce the amounts they purchase from us, do not renew their purchase contracts with us, renew their purchase contracts at less favorable terms, delay or default on their payments to us, or avoid payments to us through bankruptcy proceedings. At March 31, 2025, sales to our largest customer represented approximately 24% of our total consolidated revenues and approximately 23% of our total trade receivables, and those of our ten largest customers combined accounted for approximately 72% of our consolidated revenues and approximately 48% of our trade receivables. Refer to “Other Information about the Business” in Item 1 of Part I above for additional details on our customers. One or more customer purchase reductions, contract non-renewals, renewals at less favorable terms, payment defaults, or bankruptcies might have a materially adverse impact on our business operations and our financial position or results of operations.
Our contracts with governmental entities involve future funding and compliance risks.
Our contracts with governmental entities are subject to risks such as lack of funding and compliance with unique requirements. For example, government contract purchase obligations are typically subject to the availability of funding, which may be eliminated or reduced. In addition, the future volume of products or services purchased by a government customer is often uncertain. Our government contracts might not be renewed or might be terminated for convenience with little prior notice. They might be modified with less favorable terms. Government contracts typically expose us to higher potential liability than do other types of contracts. In addition, government contracts typically are subject to procurement laws that include socio-economic, employment practices, environmental protection, recordkeeping and accounting, and other requirements. For example, our contracts with the U.S. government generally require us to comply with the Federal Acquisition Regulation, Procurement Integrity Act, Buy American Act, Trade Agreements Act, and other laws and requirements. New or revised laws, requirements, and policies, or changes in the interpretation of existing laws, requirements, and policies, could adversely affect our business and competitiveness and increase our compliance costs. We are subject to government audits, investigations, and oversight proceedings. Governmental agencies routinely review and audit government contractors to determine whether they are complying with contractual and legal requirements. If we fail to comply with these requirements, or we fail an audit, we may be subject to various sanctions such as monetary damages, criminal and civil penalties, termination of contracts, and suspension or debarment from government contract work. These requirements complicate our business and increase our compliance burden. The occurrence of any of these risks could harm our reputation and might have a materially adverse impact on our business operations and our financial position or results of operations.

McKESSON CORPORATION
We might be harmed by changes in our relationships or contracts with suppliers.
We attempt to structure our distribution agreements with manufacturers to ensure that we are appropriately and predictably compensated for the services we provide. Certain distribution agreements with manufacturers include product price inflation as a component of our consideration, and we cannot control the frequency or magnitude of price changes. Laws limiting or reducing product prices, and changes to manufacturers’ pricing policies or practices as a result of changing laws, impact our distribution agreements. We might be unable to renew distribution agreements with manufacturers in a timely and favorable manner. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might infringe intellectual property rights or our intellectual property protections might be inadequate.
We believe that our products and services do not infringe the proprietary rights of third parties, but third parties have asserted infringement claims against us and may do so in the future. If a court were to hold that we infringed other’s rights, we might be required to pay substantial damages, develop non-infringing products or services, obtain a license, stop selling or using the infringing products or services, or incur other sanctions. We rely on trade secret, patent, copyright, and trademark laws, nondisclosure obligations, and other contractual provisions and technical measures to protect our proprietary rights in our products and solutions. We might initiate costly and time-consuming litigation to protect our trade secrets, to enforce our patent, copyright, and trademark rights, and to determine the scope and validity of the proprietary rights of others. Our intellectual property protection efforts might be inadequate to protect our rights. Our competitors might develop non-infringing products or services equivalent or superior to ours. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
Our use of third-party data is subject to risks and limitations that could impede the growth of our data services business.
We attempt to structure our processes to satisfy contractual and other operative data usage rights and limitations associated with customers, industry partners, and other third-party data flowing through our businesses. These rights and limitations can apply to confidential commercial data and personal data provided to us. Failure to satisfy these data usage rights and limitations can lead to legal claims such as contractual breaches or data protection and privacy law violations. If a court were to hold that our use of data is not consistent with our rights and limitations, we might be required to pay substantial damages; we might need to stop using, sharing, and/or selling certain products and services; or we might incur other financial, legal, and/or reputational consequences. In addition, we might be unable to negotiate and/or obtain at an acceptable cost the data usage rights needed to advance our data strategy growth and AI objectives. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be unable to successfully recruit and retain qualified employees.
Our ability to attract, engage, develop, and retain qualified and experienced employees, including key executives and other talent, is essential for us to meet our objectives. We compete with many other businesses to attract and retain employees. Competition among potential employers results in increased salaries, benefits, or other employee-related costs, or in our failure to recruit and retain employees. We may experience sudden loss of key personnel due to a variety of causes, such as illness; and although we must adequately plan for timely succession of key management roles, our succession plans might not be effective, and employees might not successfully transition into new roles. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
Industry and Economic Risks
We might be adversely impacted by healthcare reform such as changes in pricing and reimbursement models.
Many of our products and services are designed to function within the structure of current healthcare financing and reimbursement systems. The healthcare industry and related government programs are changing. Some of these changes increase our risks and create uncertainties for our business.
For example, some changes in reimbursement methodologies (including government rates) for pharmaceuticals, medical treatments, and related services reduce profit margins for us and our customers and impose new legal requirements on healthcare providers. Those changes have included cuts in Medicare and Medicaid reimbursement levels, changes in the bases for payments, shifts from fee-for-service pricing towards value-based payments and risk-sharing models, and increases in the use of managed care.

McKESSON CORPORATION
In the U.S., the ACA significantly expanded health insurance coverage to uninsured Americans and changed the way healthcare is financed by both governmental and private payors. Enactment of the IRA and its implementation over the next several years is anticipated to bring meaningful changes in how Medicare pays for drugs and various benefit design changes, which are all intended to reduce the price of drugs. Three central features of the IRA authorize the government to negotiate drug prices for certain Parts B and D drugs over time, establish an inflationary rebate program, and cap patient cost sharing under Medicare Part D. The implementation of these and other features of the IRA may result in significant changes to the pharmaceutical value chain as manufacturers, pharmacy benefit managers, managed care organizations, and other industry stakeholders look to implement new transactional flows and adapt their business models. Any such changes to arrangements involving our business as a result of this legislation, such as changes to our distribution agreements with manufacturers impacted by the IRA, may materially affect our business. The extent of the effects of the IRA remains uncertain due to a number of factors, including the potential for future regulations and guidance promulgated by HHS to implement provisions of the IRA. We continue to evaluate the impact of this law on our business.
Private challenges to government healthcare policy may also have significant impacts on our business. For example, many pharmaceutical manufacturers have unilaterally restricted sales under the Public Health Service’s 340B Drug Pricing Program (the “340B program”) to contract pharmacies. The 340B program requires manufacturers to offer discounts on certain drugs purchased by “covered entities,” which include safety-net providers. The Health Resources and Services Administration (“HRSA”) has taken the position that a covered entity may dispense such discounted drugs through multiple contract pharmacies. Starting in 2020, some manufacturers began to restrict such practices. Certain manufacturers and HHS continue to litigate these issues. The U.S. Courts of Appeal for the Third and D.C. Circuits have ruled that Section 340B of the Public Health Service Act does not require manufacturers to provide discounted drugs to an unlimited number of contract pharmacies. The U.S. Court of Appeals for the Seventh Circuit also is addressing this issue but has not yet ruled. Separately, several entities have filed lawsuits against HHS and HRSA related to the proposed implementation of rebate models to effectuate 340B pricing. Any changes to our arrangements that result from the rulings in these cases might have an adverse impact on our business.
Provincial governments in Canada that provide partial funding for the purchase of pharmaceuticals and independently regulate the sale and reimbursement of drugs have sought to reduce the costs of publicly funded health programs. For example, provincial governments have taken steps to reduce consumer prices for generic pharmaceuticals and, in some provinces, change professional allowances paid to pharmacists by generic manufacturers.
Although there is substantial uncertainty about the likelihood, timing, and results of these health reform efforts and challenges, their implementation or outcome might have a materially adverse impact on our business operations and our financial position or results of operations.
We are adversely impacted by competition and industry consolidation.
Our businesses face a highly competitive global environment with strong competition from international, national, regional, and local full-line, short-line, and specialty distributors, service merchandisers, self-warehousing chain drug stores, manufacturers engaged in direct distribution, third-party logistics companies, and large payer organizations. In addition, our businesses face competition from various other service providers and from pharmaceutical and other healthcare manufacturers as well as other potential customers, which may from time to time decide to develop, for their own internal needs, supply management capabilities that might otherwise be provided by our businesses. We also may face competition from companies that move faster to adopt emerging technologies. Due to consolidation, a few large suppliers control a significant share of the pharmaceuticals market. This concentration reduces our ability to negotiate favorable terms with suppliers and causes us to depend on a smaller number of suppliers. Many of our customers, including healthcare organizations, have consolidated or joined group purchasing organizations and have greater power to negotiate favorable prices. Consolidation by our customers, suppliers, and competitors might reduce the number of market participants and give the remaining enterprises greater bargaining power, which might lead to erosion in our profit margin. Consolidation might increase counterparty credit risk because credit purchases increase for fewer market participants. Consolidation also might affect our ability to achieve our growth objectives through acquisitions and other strategic transactions. These competitive pressures and industry consolidation might have a materially adverse impact on our business operations and our financial position or results of operations.
From time to time we have difficulties in sourcing or selling products due to a variety of causes and are adversely impacted by disruptions or changes in product supply.
We rely on third parties for the supply of pharmaceutical and other products, and our operations are subject to our suppliers’ continued ability to supply the products that we require. From time to time, we experience difficulties and delays in
21

Table of Contents | Item 1A Index

McKESSON CORPORATION
sourcing and selling products due to a variety of causes that result in suppliers’ failure to satisfy production demand. Among these causes are suppliers’ challenges in complying with legal requirements (including product and production quality standards), access to raw materials, inputs, and finished goods, manufacturing shutdowns, and operational and systems difficulties. Supply disruptions also arise from other factors beyond our control, such as product rationalization; government actions or policies (including trade sanctions, tariffs and other trade restrictions, as well as the requisition, diversion, or allocation of inventory); shifts in customer or societal demand for products; labor disputes or shortages; ethical sourcing issues; supplier financial distress; natural disasters and weather-related events; civil unrest; military conflicts; and epidemics or pandemics. In these types of situations, our alternative sourcing efforts are not always fully successful. We might experience extended delays or incur higher sourcing costs or suffer harm to our customer relationships and reputation. Furthermore, changes in the healthcare industry’s or our suppliers’ pricing, selling, inventory, distribution, or supply policies or practices could significantly reduce our revenues and net income. Any of these disruptions or changes might have a materially adverse impact on our business operations and our financial position or results of operations.
We are adversely impacted as a result of our distribution of generic pharmaceuticals.
Our generic pharmaceuticals distribution business is subject to both product availability and pricing risks. We might experience disruptions in our supply of generic pharmaceuticals. We have been impacted when, due to regulatory and supply chain challenges, our supplier partners are not able to deliver products that we have committed to source from them. Input cost increases, product discontinuations, and market shortages could result in ClarusONE, our joint venture with Walmart Inc., being unsuccessful in sourcing product to meet the needs of our customers, or could negatively impact our margin. Generic drug manufacturers offer a generic version of branded pharmaceuticals and routinely challenge the validity or enforceability of branded pharmaceutical patents in order to launch the drug pre- or post-loss of exclusivity. Patent holders have asserted infringement claims against us for distributing those generic versions they believed to have infringed a patent, and the generic drug manufacturers may not fully indemnify us against such claims. These risks and outcomes, as well as changes in the nature, frequency, or magnitude of generic pharmaceutical launches, might have a materially adverse impact on our business operations and our financial position or results of operations.
We are adversely impacted by changes in the economic environments in which we operate, including from inflation, an economic slowdown, a recession, or fluctuations in foreign currency exchange rates.
Inflationary conditions result in increased costs associated with our normal business operations and decreased levels of consumer commercial spending and, to the extent we are not able to offset such cost increases from our suppliers, increase the costs which we incur to purchase inventories and services. Inflationary pressure is increased by factors such as supply chain disruptions, labor market tightness, actual or announced tariffs, government policies, interest rate changes, and foreign exchange rate changes. An economic slowdown or a recession could also reduce the prices our customers are able or willing to pay for our products and services and reduce the volume of their purchases. In addition to rising inflation, rising interest rates, the impact of banking failures or perceived failures and related contagion, consumer sentiment, political circumstances, military conflicts, and civil unrest may contribute to recessionary pressure. Our non-U.S. operations, import and export of products sold in non-U.S. dollar (USD) denominations, non-USD intercompany loans, and our substantial international net assets also expose us to foreign currency exchange rate risk. Changes in the economic environments in which we operate might have a materially adverse impact on our business operations and our financial position or results of operations.
Changes affecting capital and credit markets might impede access to credit, increase borrowing costs, and disrupt banking services for us and our customers and suppliers and might impair the financial soundness of our customers and suppliers.
Volatility and disruption in global capital and credit markets, including the bankruptcy or restructuring of certain financial institutions, reduced lending activity by financial institutions, reduced creditworthiness of our customers or suppliers, or decreased liquidity and increased costs in the commercial paper market, might adversely affect the borrowing ability and cost of borrowing for us and our customers and suppliers. Credit rating agencies regularly review our credit and rate our outstanding debt; and any downgrades in our credit ratings might limit our access to public debt markets, decrease financial institutions willingness to lend to us, lead to more restrictive debt covenants, increase our borrowing costs, and adversely affect our earnings. We generally sell our products and services under short-term unsecured credit arrangements. An adverse change in general or entity-specific economic conditions or access to capital might cause our customers to reduce their purchases from us, or delay payments, or fail to pay amounts, owed to us. Suppliers might increase their prices, reduce their output, or change their terms of sale due to limited availability of credit. Suppliers might be unable to make payments due to us for fees, returned products, or incentives. Interest rate increases or changes in capital market conditions, including as a result of macroeconomic

events, might impede our or our customers’ or suppliers’ ability or cost to obtain credit. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be adversely impacted by tax legislation or challenges to our tax positions.
We are subject to the tax laws in the U.S. at the federal, state, and local government levels and to the tax laws of other jurisdictions in which we operate or sell products or services. Tax laws might change in ways that adversely affect our tax positions, effective tax rate, and cash flow. The tax laws are extremely complex and subject to varying interpretations. For example, the European Union and other countries (including countries in which we operate) have committed to enacting changes to numerous long-standing tax principles impacting how large multinational enterprises are taxed. In particular, the Organization for Economic Co-operation and Development’s Pillar Two initiative introduces a 15% global minimum tax applied on a country-by-country basis which many jurisdictions have enacted or committed to enact. The impact of these new and potential regulations as well as any other changes in domestic and international tax regulations could have a material effect on our effective tax rate. We are subject to tax examinations in various jurisdictions that might assess additional tax liabilities against us. Our tax reporting positions are sometimes challenged by relevant tax authorities, we might incur significant expense in our efforts to defend those challenges, and we might be unsuccessful in those efforts. Developments in examinations and challenges might materially change our provision for taxes in the affected periods and might differ materially from our historical tax accruals. Any of these risks might have a materially adverse impact on our business operations, our cash flows, and our financial position or results of operations.
General Risks
Conditions and events outside of our control, such as widespread public health issues, natural disasters, and geopolitical factors adversely impact our business operations and our financial position or results of operations.
From time to time we are adversely affected by conditions and events outside of our control, including: widespread public health issues such as epidemic or pandemic infectious diseases; natural disasters and other catastrophic events such as earthquakes, floods, or severe weather; and geopolitical factors such as terrorism, military conflicts, civil unrest, political circumstances (including changes in international relations), changes or uncertainty in government policies (including with respect to U.S. or international trade), actual or announced tariffs or other trade restrictions, or changes in laws or their interpretation. These conditions and events can disrupt operations for us, our suppliers, our vendors, and our customers, as well as impair product manufacturing, supply, and transport availability and cost in unpredictable ways that depend on highly uncertain future developments. They might affect consumer confidence levels and spending or the availability of certain goods, commodities, raw materials, and other inputs. In response to these types of conditions and events, we might seek alternate sources for product supply, incur additional sourcing or distribution costs, suspend operations, implement extraordinary procedures, or suffer consequences that are unexpected and difficult to mitigate. For example, recently imposed or announced U.S. tariffs, as well as any retaliatory tariffs or other trade restrictions imposed by other countries, might require us to incur substantial additional sourcing costs, raise prices on certain products, or seek alternate supply sources. If we are unable to effectively manage or offset the impact of new tariffs or other trade restrictions, or find alternate sources of supply, we might be competitively disadvantaged or experience reduced profit margins or supply disruptions. Further, we might suffer harm to our customer relationships. Any of the foregoing risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We may be adversely affected by global climate change or by regulatory or market responses to such change.
The long-term effects of climate change are difficult to predict and may be widespread. The impacts may include physical risks (such as rising sea levels or frequency and severity of extreme weather conditions), social and human effects (such as population dislocations or harm to health and well-being), compliance costs and transition risks (such as regulatory or technology changes), costs for critical services (such as transportation costs), and other adverse effects. The effects could impair, for example, the availability and cost of certain products, commodities, transportation, and energy (including utilities), which in turn may impact our ability to procure goods or services, and transport those goods, required for the operation of our business at the quantities and levels we require. We bear losses incurred as a result of, for example, physical damage to or destruction of our facilities (such as distribution or fulfillment centers), loss or spoilage of inventory due to unusual ambient temperatures, and business interruption due to weather events that may be attributable to climate change. These risks might have a materially adverse impact on our business operations and our financial position or results of operation.

Evolving expectations and regulatory requirements related to governance and sustainability matters may damage our reputation and have an adverse effect on our business, financial condition, and results of operations.
Investors, regulators, employees, customers, and other stakeholders continue to focus on companies’ governance and sustainability (“G&S”) practices and policies, including those related to human capital management, climate change, environmental responsibility, and social impact. Given the varied and at times divergent views of different stakeholder groups, any action or inaction by us with respect to G&S matters may be perceived negatively by some stakeholders. Furthermore, the G&S regulatory landscape is evolving and uncertain. New or revised laws and policies, or changes in the interpretation of existing laws and policies, could increase our compliance costs and expose us to legal risks. From time to time, we make statements regarding our sustainability goals. Although we intend to meet these goals, we may be required to expend significant resources to do so, which could impose costs on us. In addition, we could be criticized for the scope or nature of these goals, or for any revisions to our goals. Moreover, we may determine that it is in the best interests of the Company and our stockholders to prioritize other business investments over the achievement of our sustainability goals based on various factors such as our business strategy, technological and regulatory developments, industry standards, and input or pressure from stakeholders. If our G&S practices or outcomes do not align with stakeholder expectations or evolving regulatory requirements, our reputation, stock price, ability to access capital markets, and employee recruitment and retention efforts might be negatively affected. We also could face litigation or government action. Any of the foregoing risks might have a materially adverse impact on our business, financial condition, and results of operations.
Exclusive forum provisions in our Bylaws could limit our stockholders’ ability to choose their preferred judicial forum for disputes with us or our directors, officers, or employees.
Our amended and restated bylaws provide that, unless the Corporation consents in writing to the selection of an alternative forum, the sole and exclusive forum for specified legal actions is the Court of Chancery of the State of Delaware or the United States District Court for the District of Delaware if the Court of Chancery does not have or declines to accept jurisdiction (collectively, “Delaware Courts”). Current and former stockholders are deemed to have consented to the personal jurisdiction of the Delaware Courts in connection with any action to enforce that exclusive forum provision and to service of process in any such action. These provisions of the bylaws are not a waiver of, and do not relieve anyone of duties to comply with, federal securities laws including those specifying the exclusive jurisdiction of federal courts under the Exchange Act and concurrent jurisdiction of federal and state courts under the Securities Act. To the extent that these provisions of the bylaws limit a current or former stockholder’s ability to select a judicial forum other than the Delaware Courts, they might discourage the specified legal actions, might cause current or former stockholders to incur additional litigation-related expenses, and might result in outcomes unfavorable to current or former stockholders. A court might determine that these provisions of the bylaws are inapplicable or unenforceable in any particular action, in which case we may incur additional litigation related expenses in such action, and the action may result in outcomes unfavorable to us, which could have a materially adverse impact on our reputation, our business operations, and our financial position or results of operations.
Item 1B. Unresolved Staff Comments.
None.
Item 1C. Cybersecurity.
Risk Management and Security
As a diversified healthcare services leader that is dedicated to advancing health outcomes for patients everywhere, cybersecurity risk management is integral to our enterprise risk management strategy. Our management, with involvement and input from external consultants and oversight from our Board of Directors (“Board”), performs an annual enterprise-wide risk assessment (“ERA”) to identify key existing and emerging risks. One of the principal risks identified and assessed through this process is cybersecurity, which remains a key focus for the Company, management, and our Board.
Our Cybersecurity Risk Management Program (“RM Program”) is aligned with the National Institute of Standards and Technology Cybersecurity Framework and other industry best practices. The RM Program is designed to identify, assess and mitigate material cybersecurity risks.

McKESSON CORPORATION
We have implemented cybersecurity controls designed to protect our systems, data and operations from cybersecurity risks. Enterprise-wide cybersecurity and privacy training continue to serve an important role in risk reduction and protection of the Company and our stakeholders. We require periodic access-based and role-based privacy and cybersecurity training, which is updated to reflect changes in the threat environment, audit findings, laws, and regulations. We also engage and educate employees through cybersecurity and privacy awareness programs and communication campaigns. Our Cybersecurity Incident Response Plan (“Response Plan”) provides a framework for responding to cybersecurity incidents. The Response Plan governs activities such as preparation, detection, coordination, eradication, recovery, and appropriate escalations to the Company’s senior management, disclosure committee, Board, and relevant Board committees. The Response Plan is routinely tested, reviewed and updated as appropriate under the leadership of our Chief Information Officer and Chief Technology Officer (“CIO/CTO”) with the assistance of the Company’s Chief Information Security Officer (“CISO”).
We also engage internal and external assessors, consultants, auditors, and other third parties, to assess our RM Program . We manage cybersecurity risks associated with third parties, including vendors, service providers, and external users of our systems. This includes conducting due diligence on the third parties we use, as well as the systems of third parties that could adversely impact our business in the event of a cybersecurity incident affecting those third-party systems, and by using contracts to reinforce their cybersecurity obligations.
Although we believe that we maintain reasonable cybersecurity measures, we recognize that cyber threats continue to evolve, and no system is immune to risk.
B oth intentional and unintentional occurrences have caused, and could cause in the future, a variety of adverse business impacts to our information systems and data. For a discussion of whether and how any risks from cybersecurity threats have affected or, if realized, are reasonably likely to materially affect the Company, s ee “Risk Factors” in Item 1A of Part I above for additional information on risks related to our business, including for example, risks related to privacy and data protection, cybersecurity incidents, third-party relationships, and continuity of our information systems and networks, operational technology, and technology products or services.
Governance
Our CIO/CTO leads management’s assessment and management of cybersecurity risk with the assistance of the Company’s CISO who reports to the CIO/CTO. The CIO/CTO reports to our CFO, is a member of the Executive Operating Team, and provides updates to that group about cybersecurity matters. Our CIO/CTO has more than 29 years of experience managing technology and risks, and advising on cybersecurity issues and our CISO has more than 21 years of relevant experience, is a Certified Information System Security Professional (CISSP), and a Certified Information Systems Auditor (CISA).
C ybersecurity is among the risks identified by our ERA for Board-level oversight. The Audit Committee of the Board has oversight of information technology controls related to financial reporting, while the Compliance Committee of the Board has oversight of technology-related risk, including privacy and cybersecurity. The Audit Committee and Compliance Committee meet jointly at least annually to review cybersecurity risks and program s, and they are updated as needed on cybersecurity threats, incidents, or new developments in our cybersecurity risk profile. The chairs of the Audit Committee and Compliance Committee provide update s to the Board after each committee meeting. The CIO/CTO and CISO provide regular updates to the Board, Audit Committee, or Compliance Committee about material risks from cybersecurity threats. The CIO/CTO or CISO also provide regular updates to the Board, Audit Committee or Compliance Committee about cybersecurity trends and regulatory updates, data governance and usage, technology infrastructure, our training and compliance efforts, and implications for our business strategy. In addition to the information provided in these meetings, members of our Board have access to continuing education, which includes topics relating to cybersecurity risks.
Item 2. Properties.
Because of the nature of our principal businesses, our plant, warehousing, retail pharmacies, offices, and other facilities for all of our reportable segments are operated in widely dispersed locations, primarily throughout North America. Retail pharmacies and most warehouses are typically owned or leased on a long-term basis. We consider our operating properties to be in satisfactory condition and adequate to meet our needs for the next several years without making capital expenditures materially higher than historical levels. Information as to material lease commitments is included in Financial Note 9, “Leases,” to the consolidated financial statements included in this Annual Report.

PART II
Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters, and Issuer Purchases of Equity Securities.
Market Information: The principal market on which our common stock is traded is the New York Stock Exchange (“NYSE”) under the trading symbol “MCK.”
Holders: At March 31, 2025, there were 3,895 holders of record of our common stock.
Dividends: In July 2024, our quarterly dividend was raised from $0.62 to $0.71 per share of common stock for dividends declared on or after such date by the Board. We declared regular cash dividends of $2.75, $2.40, and $2.09 per share for the years ended March 31, 2025, 2024, and 2023, respectively.
We anticipate that we will continue to pay quarterly cash dividends in the future. However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon our future earnings, financial condition, capital requirements, legal requirements, and other factors.
Securities Authorized for Issuance under Equity Compensation Plans: Information relating to this item is provided under Item 12 of Part III included in this Annual Report.
Share Repurchase Plans: The Board has authorized the repurchase of common stock. We may affect stock repurchases from time-to-time through open market transactions, privately negotiated transactions, accelerated share repurchase (“ASR”) programs, or by combinations of such methods, any of which may use pre-arranged trading plans that are designed to meet the requirements of Rule 10b5-1(c) of the Exchange Act. The timing of any repurchases and the actual number of shares repurchased will depend on a variety of factors, including our stock price, corporate and regulatory requirements, tax implications, restrictions under our debt obligations, other uses for capital, impacts on the value of remaining shares, cash generated from operations, and market and economic conditions. During the last three fiscal years, our share repurchases were transacted through both open market transactions and ASR programs with third-party financial institutions.
Effective January 1, 2023, our repurchase of common stock, adjusted for allowable items, are subject to a 1% excise tax as a result of the IRA. Excise taxes incurred on share repurchases of an entity’s own common stock are direct and incremental costs to purchase treasury stock, and accordingly are included in the total cost basis of the common stock acquired and reflected as a reduction of stockholders’ equity within “Treasury shares” in our Consolidated Balance Sheets and Consolidated Statements of Stockholders’ Equity (Deficit). Excise taxes do not reduce our remaining authorization for the repurchase of common stock. As of March 31, 2025 and March 31, 2024 excise taxes of $26 million and $25 million were accrued within “Other accrued liabilities” in the Company’s Consolidated Balance Sheet, for shares repurchased during the years ended March 31, 2025 and 2024, respectively. On October 30, 2024, the Company made a payment of $25 million for fiscal 2024 excise taxes previously accrued.
Refer to Financi al Note 18, “Stockholders' Equity (Deficit),” to the accompanying consolidated financial statements included in this Annual Report on Form 10-K for a full discussion of the Company’s share repurchases for the years ended March 31, 2025, 2024, and 2023.

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
We report our financial results in four reportable segments: U.S. Pharmaceutical, Prescription Technology Solutions (“RxTS”), Medical-Surgical Solutions, and International. Our organizational structure also includes Corporate, which consists of income and expenses associated with administrative functions and projects, as well as the results of certain investments and operations. The factors for determining the reportable segments include the manner in which management evaluates the performance of the Company combined with the nature of individual business activities. We evaluate the performance of our operating segments on a number of measures, including revenues and operating profit (loss) before interest expense and income taxes.
The following summarizes our four reportable segments. Refer to Financial Note 20, “Segments of Business,” to the consolidated financial statements included in this Annual Report for further information regarding our reportable segments.
•U.S. Pharmaceutical is a reportable segment that distributes branded, generic, specialty, biosimilar, and over-the-counter pharmaceutical drugs and other healthcare-related products in the United States (“U.S.”). This segment also provides practice management, technology, clinical support, and business solutions to community-based oncology and other specialty practices. In addition, the segment sells financial, operational, and clinical solutions to pharmacies (retail, hospital, alternate sites) and provides consulting, outsourcing, technological, and other services.
•Prescription Technology Solutions is a reportable segment that combines automation and our ability to navigate the healthcare ecosystem to connect patients, pharmacies, providers, pharmacy benefit managers, health plans, and biopharma companies to address patients’ medication access, affordability, and adherence challenges. RxTS offers technology services, which includes electronic prior authorization, prescription price transparency, benefit insight, dispensing support services, in addition to third-party logistics, and wholesale distribution support across various therapeutic categories and temperature ranges to biopharma customers throughout the product lifecycle.
•Medical-Surgical Solutions is a reportable segment that provides medical-surgical supply distribution, logistics, and other services to healthcare providers, including physician offices, surgery centers, nursing homes, hospital reference labs, and home health care agencies. This segment offers national brand medical-surgical products as well as McKesson’s own line of high-quality products through a network of distribution centers within the U.S. In May 2025, we announced our intention to separate this segment into an independent company.
•International is a reportable segment that includes our operations in Canada and Norway, bringing together non-U.S.-based drug distribution services, specialty pharmacy, retail, and infusion care services. Our Canadian operations deliver medicines, supplies, and information technology solutions throughout Canada and included Rexall Health retail pharmacies. During fiscal 2025, we completed the sale of Rexall and Well.ca businesses in Canada (“Canadian retail disposal group”). This divestiture is further described in the “Canadian Divestiture Activities” section below. Our Norwegian operations provide distribution and services to wholesale and retail customers in Norway where we own, partner, or franchise with retail pharmacies.
Business Acquisitions and Divestitures
Community Oncology Revitalization Enterprise Ventures, LLC
On August 26, 2024, we entered into a definitive agreement to acquire a 70% controlling interest in Community Oncology Revitalization Enterprise Ventures, LLC (“Core Ventures”), an internal business and administrative services organization established by Florida Cancer Specialists & Research Institute, LLC, for approximately $2.49 billion cash, subject to certain customary adjustments. Following the completion of the transaction, Core Ventures will be part of the Oncology platform, and financial results will be reported within our U.S. Pharmaceutical segment. The waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 expired in late April 2025. We expect the transaction to close during the first quarter of fiscal 2026, subject to satisfaction of customary closing conditions.
PRISM Vision Holdings, LLC
On April 2, 2025, we announced the completion of our previously announced acquisition of a controlling interest in PRISM Vision Holdings, LLC (“PRISM Vision”), a leading provider of general ophthalmology and retina management services. We purchased an approximate 80% and PRISM Vision physicians retained a 20% interest. The financial results of PRISM Vision will be reported within our U.S. Pharmaceutical segment.

FINANCIAL REVIEW (Continued)
Canadian Divestiture Activities
On December 30, 2024, we completed the sale of our Canadian retail disposal group for an adjusted purchase price consisting of a cash payment of $9 million, received upon closing, and a note of $120 million, measured at fair value and accruing interest upon satisfaction of certain conditions, and payable to the Company at the end of six years. We recorded a charge of $667 million for the year ended March 31, 2025 in total operating expenses to remeasure the Canadian retail disposal group to fair value less costs to sell. The remeasurement adjustment includes a $48 million loss related to the accumulated other comprehensive loss balances associated with the disposal group. Refer to Financial Note 2, “Business Acquisitions and Divestitures,”, to the consolidated financial statements included in this Annual Report for more information.

•During the year ended March 31, 2025, we utilized the net proceeds from the issuance of the 2029 Notes, along with cash on hand, to redeem our $500 million outstanding principal amount of 5.25% Notes due February 15, 2026 (the “2026 Notes”) prior to maturity; and
•We returned $3.5 billion of cash to shareholders during fiscal 2025 through $3.1 billion of common stock repurchases through open market transactions and $345 million of dividend payments. In July 2024, our Board of Directors (the “Board”) approved an increase of $4.0 billion in the authorization for repurchase of the Company’s common stock and raised our quarterly dividend to $0.71 from $0.62 per share of common stock. The total remaining authorization outstanding for repurchases of the Company’s common stock at March 31, 2025 was $7.5 billion.

Trends and Uncertainties:
Opioid-Related Litigation and Claims
As described in the discussion of opioid-related matters in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual Report, we are a defendant in many legal proceedings asserting claims related to the distribution of controlled substances (opioids) in federal and state courts throughout the U.S., and in Puerto Rico and Canada. Other than as to the settlements described in Financial Note 17, “Commitments and Contingent Liabilities,”, we have not concluded a loss is probable in any of the matters; nor is any possible loss or range of loss reasonably estimable. An adverse judgment or negotiated resolution in any of these matters could have a material adverse impact on our financial position, cash flows or liquidity, or results of operations.
Rite Aid Bankruptcy Proceedings
During fiscal 2024, our customer Rite Aid Corporation (including certain of its subsidiaries, “Rite Aid”) filed a voluntary petition for reorganization under Chapter 11 of the Bankruptcy Code. As a result, we recorded a provision for bad debts of $725 million for the year ended March 31, 2024, representing the uncollected trade accounts receivable from sales to Rite Aid prior to its bankruptcy petition filing.
Rite Aid's restructuring plan was approved by the court and the company successfully emerged from bankruptcy in August 2024. During the year ended March 31, 2025, we reassessed our initial estimates made in conjunction with the previously reserved prepetition balances, including cash received during the period, resulting in a reversal of $206 million recorded within “Selling, distribution, general, and administrative expenses” in our Consolidated Statements of Operations and included within our U.S. Pharmaceutical segment. During the year ended March 31, 2025, we released $237 million of allowance for doubtful accounts against trade accounts receivables, representing the write-off of uncollectible receivables related to the Rite Aid provision in the Consolidated Balance Sheet. On May 5, 2025, Rite Aid filed a second voluntary petition under Chapter 11 of the Bankruptcy Code.
We believe the reserves maintained and any adjustments recorded for Rite Aid trade accounts receivable are appropriate and consistent with our accounting policy and assessment of the information currently available. We evaluate our reserves periodically and as circumstances warrant, which may result in changes to our reserves. For additional disclosure of our policy regarding allowances for credit losses, refer to the “Critical Accounting Estimates” section included in this Financial Review.

FINANCIAL REVIEW (Continued)
Revenues
Revenues increased for the year ended March 31, 2025 compared to the prior year largely due to market growth in our U.S. Pharmaceutical segment, including higher volumes largely from retail national account customers and growth in specialty pharmaceuticals. Market growth includes growing drug utilization and newly launched products, partially offset by branded to generic drug conversion. This revenue growth was also favorably impacted by higher pharmaceutical distribution volumes in our International segment.
Gross Profit
Gross profit increased for the year ended March 31, 2025 compared to the prior year primarily in our U.S. Pharmaceutical segment driven by growth of specialty pharmaceuticals, growth from retail national account customers, and our share of antitrust legal settlements received in fiscal 2025, partially offset by last-in, first-out (“LIFO”) inventory charges in fiscal 2025 and higher restructuring charges.
Gross profit for the years ended March 31, 2025 and 2024 included gains of $444 million and $244 million, respectively, representing our share of antitrust legal settlements. We recognized these amounts within "Cost of sales" in the Consolidated Statements of Operations within our U.S. Pharmaceutical segment.
Gross profit for the years ended March 31, 2025 and 2024 also included a LIFO charge of $82 million and a credit of $157 million, respectively. The LIFO charge in fiscal 2025 compared to a credit in fiscal 2024 was primarily due to higher brand inflation compared to the prior year. Refer to the “Critical Accounting Estimates” section included in this Financial Review for further information regarding the use of the LIFO method of accounting within our U.S. Pharmaceutical business.
Gross profit for the year ended March 31, 2025 was impacted by an inventory impairment charge of $58 million related to restructuring initiatives to drive operational efficiencies and increase cost optimization efforts as discussed in Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” to the consolidated financial statements in this Annual Report. We recorded this amount related to impairment of inventories within "Cost of sales" in the Consolidated Statements of Operations within our U.S. Pharmaceutical segment.
Total Operating Expenses
A summary and description of the components of our total operating expenses for the years ended March 31, 2025 and 2024 is as follows:
•Selling, distribution, general, and administrative expenses (“SDG&A”): consists of personnel costs, transportation costs, depreciation and amortization, lease costs, professional fee expenses, administrative expenses, provision for bad debts and related recoveries, remeasurement charges to fair value less costs to sell, and other general charges.
•Claims and litigation charges, net: These charges include adjustments for estimated probable settlements related to our controlled substance monitoring and reporting, and opioid-related claims, as well as any applicable income items or credit adjustments due to subsequent changes in estimates. Legal fees to defend claims, which are expensed as incurred, are included within SDG&A.
•Restructuring, impairment, and related charges, net: Charges recorded under this component include those incurred for programs in which we change our operations, the scope of a business undertaken by our business units, or the manner in which that business is conducted, as well as long-lived asset impairments.

Total operating expenses and total operating expenses as a percentage of revenues decreased for the year ended March 31, 2025 compared to the prior year. Total operating expenses for the years ended March 31, 2025 and 2024 were affected by the following significant items:
Fiscal 2025
•SDG&A includes charges of $667 million to remeasure our Canadian retail disposal group to fair value less costs to sell. The remeasurement adjustment includes a $48 million loss related to the accumulated other comprehensive loss balances associated with this disposal. Of the total charges recorded during the period, $605 million are included within our International segment and $62 million are included within Corporate expenses, net;
•SDG&A includes a credit of $206 million related to the bankruptcy of Rite Aid. Refer to the Rite Aid Bankruptcy Proceedings section of “Trends and Uncertainties” for further discussion;
•Claims and litigation charges, net primarily consists of a charge of $108 million related to our estimated liability for opioid-related claims as discussed in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual Report; and
•Restructuring, impairment, and related charges, net of $286 million, are discussed below under “Restructuring Initiatives” as well as Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” to the consolidated financial statements included in this Annual Report.
Fiscal 2024
•SDG&A includes a provision for bad debts of $725 million related to the bankruptcy of Rite Aid in October 2023. Refer to the Rite Aid Bankruptcy Proceedings section of “Trends and Uncertainties” for more information;
•SDG&A includes a fair value adjustment gain of $78 million which reduced our contingent consideration liability related to the Rx Savings Solutions, LLC (“RxSS”) acquisition, as discussed in more detail in Financial Note 2, “Business Acquisitions and Divestitures” to the consolidated financial statements included in this Annual Report;
•SDG&A was impacted by lower operating expenses from the completed divestiture of our E.U. disposal group in fiscal 2023, as discussed in more detail in Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report;
•Claims and litigation charges, net primarily consists of a charge of $149 million related to our estimated liability for opioid-related claims as discussed in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual Report; and
•Restructuring, impairment, and related charges, net of $115 million are primarily related to Corporate expenses, net.

Goodwill Impairment
We evaluate goodwill for impairment on an annual basis in the first fiscal quarter, and at an interim date if indicators of potential impairment exist. The annual impairment testing performed in fiscal 2025 and fiscal 2024 did not indicate any impairment of goodwill, and no goodwill impairment charges were recorded in fiscal 2025 and fiscal 2024. However, other risks, expenses, and future developments, such as government actions, increased regulatory uncertainty, and material changes in key market assumptions limit our ability to estimate projected cash flows, which could adversely affect the fair value of various reporting units in future periods. Refer to the “Critical Accounting Estimates” included in this Financial Review for further information.
Restructuring Initiatives
We recorded restructuring, impairment, and related charges of $286 million and $115 million for the years ended March 31, 2025 and 2024, respectively. These charges were included in “Restructuring, impairment, and related charges, net” in the Consolidated Statements of Operations.
During the second quarter of fiscal 2025, we approved enterprise-wide initiatives to modernize and accelerate our technology service operating model, which are intended to improve business continuity, compliance, operating efficiency and advance investments to streamline the organization. These initiatives include cost reduction efforts and support other rationalization efforts within Corporate, and the Medical-Surgical Solutions, and U.S. Pharmaceutical segments to help realize long-term sustainable growth. We anticipate total charges related to these initiatives of $650 million to $700 million, consisting primarily of employee severance and other employee-related costs as well as facility, exit and other related costs, including long-lived asset impairments. These programs are anticipated to be substantially complete in fiscal 2028. For the year ended March 31, 2025, we recorded charges of $240 million related to the initiatives, which primarily includes severance and other employee-related costs as well as facility exit and other related costs, including long-lived asset impairments recorded within “Restructuring, impairment, and related charges, net” in the Consolidated Statements of Operations, and $58 million for the year ended March 31, 2025 related to inventory impairments recorded within “Cost of sales” in the Consolidated Statements of Operations.
During the fourth quarter of fiscal 2023, we approved a broad set of initiatives to drive operational efficiencies and increase cost optimization efforts, with the intent of simplifying our infrastructure and realizing long-term sustainable growth. These initiatives included headcount reductions and the exit or downsizing of certain facilities. We recorded charges of $45 million for the year ended March 31, 2024 related to this program. This restructuring program was substantially complete in fiscal 2024.
Refer to Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” to the consolidated financial statements included in this Annual Report for more information.
Other Income, Net
Other income, net increased for the year ended March 31, 2025 compared to fiscal 2024 primarily due to net gains of $101 million related to our investments in equity securities of certain U.S. growth stage companies in the healthcare industry and a favorable impact from interest income, partially offset by charges of $87 million related to the termination of the U.K. pension plan and a loss of $43 million related to one of our equity method investments.
Interest Expense
Interest expense increased in fiscal 2025 compared to the prior year primarily due to increased average balances of the Company’s loan portfolio in fiscal 2025, and a prior year gain on debt extinguishment of $9 million. These increases were partially offset by increased capitalized interest from higher capital spending, changes in our derivative portfolio in fiscal 2025, and a decline in commercial paper borrowings in fiscal 2025 compared to fiscal 2024. Refer to Financial Note 11, “Debt and Financing Activities,” to the consolidated financial statements included in this Annual Report for more information. Interest expense may fluctuate based on timing, amounts, and interest rates of term debt repaid and new term debt issued, amounts and interest rates of commercial paper borrowings, as well as amounts incurred associated with financing fees.
Income Tax Expense
We recorded income tax expense of $878 million and $629 million for the years ended March 31, 2025 and 2024, respectively. Our reported income tax expense rates were 20.1% and 16.6% in 2025 and 2024, respectively.

Table of Contents | MD&A Index

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
Fluctuations in our reported income tax rates are primarily due to changes in our business mix of earnings between various taxing jurisdictions, including the impact of non-cash pre-tax charges related to the remeasurement of our Canadian retail disposal group to fair value less costs to sell as described in Financial Note 2, “Business Acquisitions and Divestitures,” and recognized discrete tax items.
For the year ended March 31, 2025, we recognized a net discrete tax benefit of $258 million related to the sales of certain intellectual property between McKesson wholly-owned legal entities based in foreign tax jurisdictions. For the year ended March 31, 2024, we recognized a net discrete tax benefits of $157 million related to the release of a valuation allowance based on management’s reassessment of the amount of our deferred tax assets that are more likely than not to be realized and $104 million related to the repatriation and sale of certain intellectual property between McKesson wholly-owned legal entities that are based in different tax jurisdictions. Refer to Financial Note 6, “Income Taxes,” to the consolidated financial statements included in this Annual Report for more information.
Significant judgments and estimates are required in determining the consolidated income tax provision and evaluating income tax uncertainties. Although our major taxing jurisdictions include the U.S. and Canada, we are subject to income taxes in numerous foreign jurisdictions. Our income tax expense, deferred tax assets and liabilities, and uncertain tax liabilities reflect management’s best assessment of estimated current and future taxes to be paid. We believe that we have made adequate provision for all income tax uncertainties.
Net Income Attributable to Noncontrolling Interests
Net income attributable to noncontrolling interests for the years ended March 31, 2025 and 2024 primarily represents the proportionate results of third-party equity interests in ClarusONE Sourcing Services LLP, Vantage Oncology Holdings, LLC, and SCRI Oncology, LLC. The increase in net income attributable to noncontrolling interests was primarily driven by higher volumes in our ClarusONE joint venture.
Net Income Attributable to McKesson Corporation
Net income attributable to McKesson Corporation was $3.3 billion and $3.0 billion for the years ended March 31, 2025 and 2024, respectively. Diluted earnings per common share attributable to McKesson Corporation was $25.72 and $22.39 for the years ended March 31, 2025 and 2024, respectively. Our diluted earnings per share includes the cumulative effects of share repurchases during each period.
Weighted-Average Diluted Common Shares Outstanding
Diluted earnings per common share was calculated based on a weighted-average number of shares outstanding of 128.1 million and 134.1 million for the years ended March 31, 2025 and 2024, respectively. Weighted-average diluted shares outstanding for fiscal 2025 decreased from the prior year primarily due to the cumulative effect of share repurchases, as discussed in the “Share Repurchases Plans” section of this Financial Review.

U.S. Pharmaceutical
U.S. Pharmaceutical revenues for the year ended March 31, 2025 increased $49.0 billion or 18% compared to the prior year. Within the segment, sales to pharmacies and healthcare providers increased $42.6 billion and sales to specialty practices and other increased $6.4 billion. Overall, these increases were primarily due to higher volumes from retail national account customers and growth in specialty pharmaceuticals, partially offset by branded to generic drug conversions.
Prescription Technology Solutions
RxTS revenues for the year ended March 31, 2025 increased $447 million or 9% compared to the prior year due to increased volumes from our third-party logistics and higher technology services revenues.
Medical-Surgical Solutions
Medical-Surgical Solutions revenues for the year ended March 31, 2025 increased $73 million or 1% compared to the prior year. Within the segment, sales to primary care customers increased $85 million, partially offset by other sales which declined $10 million driven by lower contribution from the kitting and distribution of ancillary supplies used to administer COVID-19 vaccines, and sales to extended care customers which decreased $2 million.
International
International revenues for the year ended March 31, 2025 increased $591 million or 4% compared to the prior year which included $455 million unfavorable effects of foreign currency exchange fluctuations. Within the segment, sales in Canada increased by $950 million largely driven by higher pharmaceutical distribution volumes and sales in Norway increased by $96 million primarily driven by growth in retail pharmacy.
Corporate
Corporate reflects revenues from services derived in the U.S. related to certain technology operations. The increase compared to the prior year was immaterial.

U.S. Pharmaceutical
Operating profit increased for the year ended March 31, 2025 compared to the prior year primarily due to a prior year provision for bad debts of $725 million and a fiscal 2025 credit of $206 million related to the reassessment of our initial estimates made in conjunction with the previously reserved prepetition balances owed by Rite Aid, growth in specialty pharmaceuticals and retail national account customers, and an increase in net cash proceeds received representing our share of antitrust legal settlements. These increases were partially offset by a LIFO charge in fiscal 2025 compared to a credit in the prior year period, an increase in operating expenses to support higher volumes, a charge of $57 million related to our estimated liability for opioid-related claims, and a loss related to one of our equity method investments.
Prescription Technology Solutions
Operating profit increased for the year ended March 31, 2025 compared to the prior year primarily driven by contributions from technology services partially offset by the gain of $78 million recognized in the prior year resulting from a fair value adjustment of our contingent consideration liability related to the RxSS acquisition.
Medical-Surgical Solutions
Operating profit decreased for the year ended March 31, 2025 compared to the prior year primarily due to higher restructuring charges recorded in fiscal 2025 and a decline in the contribution from our primary care business, partially offset by lower expenses resulting from business rationalization initiatives.
International
Operating (loss) for this segment for the year ended March 31, 2025 compared to an operating profit for the prior year was largely due to remeasurement charges related to our Canadian retail disposal group, as discussed in Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report.
Corporate
Corporate expenses, net decreased for the year ended March 31, 2025 compared to the prior year primarily due to a net gain of $101 million related to our investments in equity securities of certain U.S. growth stage companies in the healthcare industry, a favorable impact to interest income, and lower charges related to our estimated liability for opioid-related claims. These were partially offset by a fiscal 2025 charge of $87 million related to the termination of the U.K. pension plan, remeasurement charges related to our Canadian retail disposal group, as discussed in Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report, and higher restructuring charges recorded in fiscal 2025 compared to the prior year.

FOREIGN OPERATIONS
Our foreign operations represented approximately 4% and 5% of our consolidated revenues in fiscal 2025 and fiscal 2024, respectively. Foreign operations are subject to certain risks, including currency fluctuations. Refer to Item 1A - Risk Factors in Part I of this Annual Report for a risk factor related to fluctuations in foreign currency exchange rates, and risks from trade and tariffs. We monitor our operations and adopt strategies responsive to changes in the economic and political environment in each of the countries in which we operate. We conduct our business worldwide in local currencies, including the Canadian dollar and Euro. As a result, the comparability of our results reported in U.S. dollars can be affected by changes in foreign currency exchange rates. In discussing our operating results, we may use the term “foreign currency exchange fluctuations,” which refers to the effect of changes in foreign currency exchange rates used to convert the local currency results of our operations in foreign countries where the functional currency is not the U.S. dollar. We present this information to provide a framework for assessing how our business performed excluding the effect of foreign currency exchange rate fluctuations. In computing the foreign currency exchange fluctuations, we translate our current year results of our operations in foreign countries recorded in local currencies into U.S. dollars by applying their respective average foreign currency exchange rates of the corresponding prior year periods, and we subsequently compare those results to the previously reported results of the comparable prior year periods reported in U.S. dollars.
In fiscal 2025, we completed the sale of our Canadian retail disposal group. Refer to Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report for more information.
Additional information regarding our foreign operations is also included in Financial Note 20, “Segments of Business,” to the consolidated financial statements included in this Annual Report.
BUSINESS COMBINATIONS
Refer to Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report for additional information.
FISCAL 2026 OUTLOOK
Information regarding the Company’s fiscal 2026 outlook is contained in the release of our fourth quarter fiscal 2025 financial results included as an exhibit to our Form 8-K furnished to the SEC on May 8, 2025, which is not incorporated by reference into this Annual Report. That Form 8-K should be read in conjunction with the cautionary statements in Item 1 - Business - Forward-Looking Statements and Item 1A - Risk Factors, in Part I of this Annual Report.
CRITICAL ACCOUNTING ESTIMATES
We consider an accounting estimate to be critical if the estimate requires us to make assumptions about matters based upon past experience and management’s judgment that were uncertain at the time the accounting estimate was made and if different estimates that we reasonably could have used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, could have a material impact on our financial condition or results from operations. Below are the estimates that we believe are critical to the understanding of our operating results and financial condition. Other accounting policies are described in Financial Note 1, “Significant Accounting Policies,” to the consolidated financial statements included in this Annual Report. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates.
Allowances for Credit Losses: Our receivables primarily consist of short-term trade accounts receivable from customers that result from the sale of goods and services. We also provide customer financing arrangements to customers who purchase our products and services. Customer financing primarily relates to guarantees provided to our customers, or their creditors, regarding the repurchase of inventories. We also provide financing to certain customers related to the purchase of pharmacies, which serve as collateral for the loans. We estimate the receivables for which we do not expect full collection based on historical collection rates and specific knowledge regarding the current creditworthiness of our customers and record an allowance in our consolidated financial statements for these amounts.

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
The Company considers historical credit losses, the current economic environment, customer credit ratings, collections on past due amounts, legal disputes, and bankruptcies, as well as reasonable and supportable forecasts to develop its allowance for credit losses. Management reviews these factors quarterly to determine if any adjustments are needed to the allowance.
Sales to the Company’s ten largest customers, including group purchasing organizations (“GPOs”), accounted for approximately 72% of total consolidated revenues in fiscal 2025 and comprised approximately 48% of total trade accounts receivable at March 31, 2025. Sales to our largest customer, CVS Health Corporation (“CVS”), accounted for approximately 24% of our total consolidated revenues in fiscal 2025 and comprised approximately 23% of total trade accounts receivable at March 31, 2025. As a result, our sales and credit concentration is significant. We also have agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies and other healthcare providers, as well as with government entities and agencies. The accounts receivable balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. A material default in payment, a material reduction in purchases from GPOs or any other large customers, or the loss of a large customer or GPO could have a material adverse impact on our financial position, results of operations, and liquidity.
Reserve methodologies are assessed annually based on historical losses and economic, business, and market trends. In addition, reserves are reviewed quarterly and updated if unusual circumstances or trends are present. We believe the reserves maintained and expenses recorded in fiscal 2025 are appropriate and consistent in the context of historical methodologies employed, as well as assessment of trends currently available.
At March 31, 2025, trade and notes receivables were $22.6 billion prior to allowances of $472 million. Our provision for bad debts was a credit of $130 million, in fiscal 2025 and a charge of $819 million, and $45 million in fiscal 2024 and fiscal 2023, respectively. At March 31, 2025 and 2024, the allowance as a percentage of trade and notes receivables was 2.1% and 4.5%, respectively. The provision for bad debts for fiscal 2024 included a charge of $725 million within our U.S. Pharmaceutical segment related to the bankruptcy of our customer Rite Aid, as discussed in the “Trends and Uncertainties” section of this financial review and the Financial Note 20, “Segments of Business,” to the consolidated financial statements included in this Annual Report. This amount represented the uncollected trade accounts receivable balance due from Rite Aid prior to its bankruptcy petition filing in October 2023. During the year ended March 31, 2025, we reassessed our initial estimates made in conjunction with the previously reserved prepetition balances, including cash received during the period, resulting in a reversal of $206 million recorded within “Selling, distribution, general, and administrative expenses” in our Consolidated Statements of Operations and included within our U.S. Pharmaceutical segment. During the year ended March 31, 2025, we released $237 million of allowance for doubtful accounts against trade accounts receivables, representing the write-off of uncollectible receivables related to the Rite Aid provision in the Consolidated Balance Sheet.
An increase or decrease of a hypothetical 0.1% in the fiscal 2025 allowance as a percentage of trade and notes receivables would result in an increase or decrease in the provision for bad debts of approximately $23 million. The selected 0.1% hypothetical change does not reflect what could be considered the best or worst-case scenarios. Additional information concerning our allowances for credit losses may be found in Schedule II included in this Annual Report.
Inventories: Inventories consist of merchandise held for resale. We report inventories at the lower of cost or net realizable value, except for inventories determined using the LIFO method which are valued at the lower of LIFO cost or market. The LIFO method presumes that the most recent inventory purchases are the first items sold and the inventory cost under LIFO approximates market. The majority of the cost of domestic inventories is determined using the LIFO method. The majority of the cost of inventories held in foreign and certain domestic locations is based on the first-in, first-out (“FIFO”) method or weighted-average purchase prices. Rebates, cash discounts, and other incentives received from vendors relating to the purchase or distribution of inventory are considered product discounts and are accounted for as a reduction in the cost of inventory and are recognized when the inventory is sold.
In determining whether an inventory valuation allowance is required, we consider various factors including estimated quantities of slow-moving inventory by reviewing on-hand quantities, outstanding purchase obligations, and forecasted sales. Shifts in market trends and conditions, changes in customer preferences due to the introduction of generic drugs or new pharmaceutical products, or the loss of one or more significant customers are factors that could affect the value of our inventories. We write down inventories which are considered excess and obsolete as a result of these reviews. These factors could make our estimates of inventory valuation differ from actual results.

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
At March 31, 2025 and 2024, total inventories, net were $23.0 billion and $21.1 billion, respectively, in our Consolidated Balance Sheets. The LIFO method was used to value approximately 63% and 62% of our inventories at March 31, 2025 and 2024, respectively. If we had used the moving average method of inventory valuation, inventories would have been approximately $309 million and $227 million higher than the amounts reported at March 31, 2025 and 2024, respectively. These amounts are equivalent to our LIFO reserves. A LIFO charge is recognized when the net effect of price increases on pharmaceutical and non-pharmaceutical products held in inventory exceeds the impact of price declines, including the effect of branded pharmaceutical products that have lost market exclusivity. A LIFO credit is recognized when the net effect of price declines exceeds the impact of price increases on pharmaceutical and non-pharmaceutical products held in inventory. We recognized a LIFO charge of $82 million in fiscal 2025, a LIFO credit of $157 million in fiscal 2024, and a LIFO charge of $1 million in fiscal 2023, all within “Cost of sales” in our Consolidated Statements of Operations. The LIFO charge in fiscal 2025 compared to a LIFO credit in fiscal 2024 was primarily due to higher brand inflation in the current fiscal year. The LIFO credit in fiscal 2024 compared to a LIFO charge in fiscal 2023 was primarily due to lower brand inflation, offset by higher brand inventory levels, lower deflation from off patent launch activity, and lower generics deflation. Our LIFO valuation amount includes both pharmaceutical and non-pharmaceutical products.
We believe that the moving average inventory costing method provides a reasonable estimation of the current cost of replacing inventory (i.e., “market”). As such, our LIFO inventory is valued at the lower of LIFO cost or market. As of March 31, 2025 and 2024, inventories at LIFO did not exceed market.
Business Combinations: We account for business combinations using the acquisition method of accounting whereby the identifiable assets and liabilities of the acquired business, including contingent consideration, as well as any noncontrolling interest in the acquired business, are recorded at their estimated fair values as of the date that we obtain control of the acquired business. Any purchase consideration in excess of the estimated fair values of the net assets acquired is recorded as goodwill. Acquisition-related expenses and related restructuring costs are expensed as incurred.
Several valuation methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, we typically use a variation of the income approach, whereby a forecast of future cash flows attributable to the asset is discounted to present value using a risk-adjusted discount rate. Some of the more significant estimates and assumptions inherent in the income approach include the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows, and the assessment of the asset’s expected useful life. Refer to Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report for additional information regarding our acquisitions.
Certain business combinations involve the potential for future payments of consideration that is contingent upon the achievement of performance milestones or other agreed-upon events. The liability for the contingent consideration is measured at its fair value as of the acquisition date using unobservable inputs. These inputs include the estimated amount and timing of projected operational and financial information, the probability of achievement of performance milestones or other agreed-upon events, and the risk-adjusted discount rate used to calculate the present value of the probability-weighted projected financial information. Contingent liabilities are remeasured to fair value at each reporting date until the liability is resolved with changes in fair value being recognized within “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations. Changes in any of the inputs may result in a significant adjustment to the fair value.
Goodwill and Long-Lived Assets:
Goodwill
As a result of acquiring businesses, we have $10.0 billion and $10.1 billion of goodwill at March 31, 2025 and 2024, respectively, and $1.5 billion and $2.1 billion of intangible assets, net at March 31, 2025 and 2024, respectively.
We perform an impairment test on goodwill balances annually in the first fiscal quarter and more frequently if indicators for potential impairment exist. Indicators that are considered include significant declines in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, or a significant decline in the Company’s stock price and/or market capitalization for a sustained period of time.
Goodwill impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or a component, one level below our operating segments, for which discrete financial information is available and where segment management regularly reviews the operating results of that reporting unit.
45

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
We apply the goodwill impairment test by comparing the estimated fair value of a reporting unit to its carrying value and an impairment charge is recorded equal to the amount of excess carrying value above the estimated fair value, if any, but not to exceed the amount of goodwill allocated to the reporting unit.
To estimate the fair value of our reporting units, we generally use a combination of the market approach and the income approach. Under the market approach, we estimate fair value by comparing the business to similar businesses, or guideline companies whose securities are actively traded in public markets. Under the income approach, we use a discounted cash flow model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate that is commensurate with the risk inherent within the reporting unit. In addition, we compare the aggregate of the reporting units’ fair values to our market capitalization as further corroboration of the reasonableness of our concluded fair values.
Estimates of fair value result from a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions at a point in time. Judgments made in determining an estimate of fair value may materially impact our results of operations. The valuations are based on information available as of the impairment testing date and are based on expectations and assumptions that have been deemed reasonable by management. Any material changes in key assumptions, including failure to meet business plans, negative changes in government reimbursement rates, deterioration in the U.S. and global financial markets, an increase in interest rates, or an increase in the cost of equity financing by market participants within the industry, or other unanticipated events and circumstances may decrease the projected cash flows or increase the discount rates and could potentially result in an impairment charge. Under the market approach, significant estimates and assumptions also include the selection of appropriate guideline public companies and the determination of appropriate valuation multiples to apply to the reporting unit. Under the income approach, significant estimates and assumptions also include the determination of discount rates. The discount rates represent the weighted-average cost of capital measuring the reporting unit’s cost of debt and equity financing, which are weighted by the percentage of debt and percentage of equity in a company’s target capital structure. Included in the estimate of the weighted-average cost of capital is the assumption of an unsystematic risk premium to address incremental uncertainty related to the reporting units’ future cash flow projections.
The annual impairment testing performed for fiscal 2025, fiscal 2024, and fiscal 2023 did not indicate any impairment of goodwill.
Refer to Financial Note 10, “Goodwill and Intangible Assets, Net,” to the consolidated financial statements included in this Annual Report for additional information.
Long-Lived Assets
Currently, all of our identifiable intangible and other long-lived assets are amortized or depreciated based on the pattern of their economic consumption or a straight-line basis over their estimated useful lives, ranging from one to 30 years. We review intangible and other long-lived assets for impairment at an asset group level whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability of intangible and other long-lived assets is based on the lowest level of identifiable estimated future undiscounted cash flows resulting from the use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset group over its fair value. Assumptions and estimates about future values and the remaining useful lives of our purchased intangible assets are complex and subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts.
Our ongoing consideration of all the factors described previously could result in further impairment charges in the future, which could adversely affect our net income. Refer to Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” to the consolidated financial statements included in this Annual Report for additional information on our long-lived asset impairments.

Table of Contents | MD&A Index

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
Long-lived assets classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell and are not depreciated or amortized. Fair value is determined based on the total consideration expected to be received by the Company. The fair value of a disposal group, less any costs to sell, is assessed each reporting period it remains classified as held for sale and any remeasurement to the lower of carrying value or fair value less costs to sell is reported as an adjustment to the carrying value of the disposal group. When the net realizable value of a disposal group increases during a period, a gain can be recognized to the extent that it does not increase the value of the disposal group beyond its original carrying value when the disposal group was reclassified as held for sale.
Restructuring Charges: We have certain restructuring reserves which require significant estimates related to the timing and amount of future employee severance and other exit-related costs to be incurred when the restructuring actions take place. We generally recognize employee severance costs when payments are probable and amounts can be reasonably estimated. Costs related to contracts without future benefit or contract termination are recognized at the earlier of the contract termination or the cease-use dates. Other exit-related costs are expensed as incurred. In connection with these restructuring actions, we also assess the recoverability of long-lived assets used in the business, and as a result, we may recognize accelerated depreciation and amortization reflecting shortened useful lives of the underlying assets. Refer to Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” to the consolidated financial statements included in this Annual Report for additional information on restructuring matters.
Income Taxes: Our income tax expense and deferred tax assets and liabilities reflect management’s best assessment of estimated current and future taxes to be paid. We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgments and estimates are required in determining the consolidated income tax provision and in evaluating income tax uncertainties, including those used to conclude on the unrecognized tax position related to opioid-related litigation and claims, and may differ from the actual amounts of tax benefit recognized. We review our tax positions at the end of each quarter and adjust the balances as new information becomes available.
Deferred income taxes arise from temporary differences between the tax and financial statement recognition of revenue and expense. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence including our past operating results, the existence of cumulative net operating losses in the most recent years, and our forecast of future taxable income. In estimating future taxable income, we develop assumptions including the amount of future federal, state, and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we use to manage the underlying businesses.
Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Should tax laws change, our tax expense and cash flows could be materially impacted.
In addition, the calculation of our tax liabilities includes estimates for uncertainties in the application of complex new tax regulations across multiple global jurisdictions where we conduct our operations.
We recognize liabilities for tax and related interest for issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and related interest will be due. If our current estimate of tax and interest liabilities is less than the ultimate settlement, an additional charge to income tax expense may result. If our current estimate of tax and interest liabilities is more than the ultimate settlement, a reduction to income tax expense may be recognized. Refer to Financial Note 6, “Income Taxes,” to the consolidated financial statements included in this Annual Report for additional information on income tax matters.

FINANCIAL REVIEW (Continued)
Loss Contingencies: We are subject to various claims, including claims with customers and vendors, pending and potential legal actions for damages, investigations relating to laws and regulations and other matters arising out of the normal conduct of our business. When a loss is considered probable and reasonably estimable, we record a liability in the amount of our best estimate for the ultimate loss. However, the likelihood of a loss with respect to a particular contingency is often difficult to predict, and determining a meaningful estimate of the loss or a range of loss may not be practicable based on the information available and the potential effect of future events and decisions by third parties that will determine the ultimate resolution of the contingency. Moreover, it is not uncommon for such matters to be resolved over many years, during which time relevant developments and new information must be reevaluated at least quarterly to determine both the likelihood of potential loss and whether it is possible to reasonably estimate a range of possible loss. When a material loss is reasonably possible, or probable but a reasonable estimate cannot be made, disclosure of the proceeding is provided. Legal fees are expensed as incurred when the legal services are provided.
We review all contingencies at least quarterly to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the potential loss or range of the loss can be made. As discussed above, development of a meaningful estimate of loss or a range of potential loss is complex when the outcome is directly dependent on future negotiations with or decisions by third parties, such as regulatory agencies, the court system, and other interested parties.
In conjunction with the preparation of the consolidated financial statements included in this Annual Report, we considered matters related to ongoing controlled substances claims to which we are a party. For the year ended March 31, 2024, the Company recorded a charge of $149 million within “Claims and litigation charges, net” in the Consolidated Statement of Operations to reflect its portion of a proposed settlement with a nationwide class of acute care hospitals, and the corresponding liability was included within “Other accrued liabilities” in the Consolidated Balance Sheet. For the year ended March 31, 2025, we recorded a charge of $114 million within “Claims and litigation charges, net” in the Consolidated Statement of Operations to reflect the Company’s portion of the settlement with representatives of a nationwide group of certain third-party payors, of which $57 million was recorded within Corporate expenses, net, and U.S. Pharmaceutical, respectively. The corresponding liability was included within “Other accrued liabilities” in the Consolidated Balance Sheet. At March 31, 2025, our estimated accrued liability for opioid-related claims was $6.4 billion. Because of the many uncertainties associated with the remaining opioid-related litigation matters, we are not able to reasonably estimate the upper or lower ends of the range of ultimate possible losses for all opioid-related litigation matters. We are not able to predict the outcome in these matters, and an adverse judgment or negotiated resolution in any of these matters could have a material adverse effect on our results of operations, financial position, and cash flows or liquidity. Refer to Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual Report for additional information.

FINANCIAL CONDITION, LIQUIDITY, AND CAPITAL RESOURCES
We expect our available cash generated from operations and our short-term investment portfolio, together with our existing sources of liquidity from our credit facilities, commercial paper program, and other borrowings will be sufficient to fund our short-term and long-term capital expenditures, working capital, and other cash requirements. We remain adequately capitalized, including access to liquidity from our $4.0 billion revolving credit facility. At March 31, 2025, we were in compliance with all debt covenants, and believe we have the ability to continue to meet our debt covenants in the future.
The following table summarizes the net change in cash, cash equivalents, and restricted cash for the periods shown:

| Years Ended March 31, |  |
(Dollars in millions) | 2025 |  | 2024 |  | Change
Net cash provided by (used in): |  |  |  |  |
Operating activities | $ | 6,085 |  |  | $ | 4,314 |  |  | $ | 1,771 |
Investing activities | (733) |  |  | (1,072) |  |  | 339 |

Net change in cash, cash equivalents, and restricted cash | $ | 1,371 |  |  | $ | (94) |  |  | $ | 1,465 |

Operating Activities
Operating activities provided cash of $6.1 billion and $4.3 billion for the years ended March 31, 2025 and 2024, respectively. Cash flows from operations can be significantly impacted by factors such as the timing of receipts from customers, inventory receipts, and payments to vendors. Additionally, working capital is primarily a function of sales and purchase volumes, inventory requirements, and vendor payment terms.
For the year ended March 31, 2025, net cash provided by operating activities increased by $1.8 billion compared to the prior year period. This increase was primarily due to the following:
•the Company’s net income increased by $321 million and was favorably impacted by higher net non-cash items of $549 million, compared to the prior year period driven by factors discussed in more detail in the “Overview of Consolidated Results” section of this Financial Review, including an increase in cash receipts for our share of antitrust legal settlements of $200 million;
•an increase in cash of $3.7 billion related to accounts payable as a result of customary vendor payment scheduling, and higher purchases to support business growth, partially offset by timing related to the day of the week on which the period ends;
•a decrease in net cash of $981 million related to accounts receivable primarily due to growth in specialty pharmaceuticals sales and higher volumes from retail national account customers in our U.S. Pharmaceutical segment;
•a decrease in net cash of $976 million related to higher inventory purchases to support business growth; and
•a decrease in cash driven by higher income tax payments in fiscal 2025 compared to the prior year.
Investing Activities
Investing activities used cash of $733 million and $1.1 billion for the years ended March 31, 2025 and 2024, respectively. Investing activities for the year ended March 31, 2025 includes $537 million and $322 million, respectively, in capital expenditures for property, plant, and equipment and capitalized software. Investing activities for the year ended March 31, 2025 was also impacted by the receipt of proceeds of $189 million related to investments in equity securities, as discussed in Financial Note 15, “Fair Value Measurements,” to the consolidated financial statements included in this Annual Report.
Investing activities for the year ended March 31, 2024 includes $431 million and $256 million, respectively, in capital expenditures for property, plant, and equipment and capitalized software, as well as $272 million of net cash payments for acquisitions.

Financing Activities
Financing activities used cash of $4.0 billion and $3.3 billion for the years ended March 31, 2025 and 2024, respectively. Financing activities for the year ended March 31, 2025 includes $3.1 billion of cash paid for share repurchases and $345 million of cash paid for dividends. Financing activities also includes cash receipts and cash payments of $15.1 billion related to short-term borrowings of commercial paper in fiscal 2025. On September 10, 2024, we completed a public offering of 4.25% Notes due September 15, 2029 in a principal amount of $500 million. Proceeds received from this note issuance, net of discounts and offering expenses, were $496 million. We utilized the net proceeds from this note issuance along with cash on hand to redeem our $500 million outstanding principal amount of 5.25% Notes due February 15, 2026 prior to maturity at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest through the settlement date.
Financing activities for the year ended March 31, 2024 includes $3.0 billion of cash paid for share repurchases and $314 million of cash paid for dividends. Financing activities also includes cash receipts and cash payments of $20.0 billion related to short-term borrowings of commercial paper in fiscal 2024.
On June 15, 2023, we completed a public offering of 4.90% Notes due July 15, 2028 in a principal amount of $400 million and 5.10% Notes due July 15, 2033 in a principal amount of $600 million, for proceeds received, net of discounts and offering expenses, of $397 million and $592 million, respectively. A portion of the net proceeds from these notes was utilized to fund the repurchase of our then outstanding 3.80% Notes due March 15, 2024 (the “2024 Notes”) discussed below, while the remaining net proceeds was available for general corporate purposes.
On June 16, 2023, we completed a cash tender offer for any and all of our then outstanding 2024 Notes with a principal amount of $918 million, which was made concurrently with the June 15, 2023 notes offering described above. Using a portion of the proceeds from the June 15, 2023 notes offering, we paid an aggregate consideration of $268 million to repurchase $271 million principal amount of the 2024 Notes. Following the consummation of this tender offer, on June 16, 2023, we irrevocably deposited U.S. government obligations with the trustee under the indenture governing the 2024 Notes sufficient to fund the payment of accrued and unpaid interest of the remaining $647 million principal amount of the 2024 Notes as it became due, and of the principal amount of those 2024 Notes on their March 15, 2024 maturity date.
Cash used for other financing activities generally includes shares surrendered for tax withholding and payments to noncontrolling interests.
Share Repurchase Plans
The Board has authorized the repurchase of common stock. We may repurchase common stock from time-to-time through open market transactions, privately negotiated transactions, accelerated share repurchase programs, or by combinations of such methods, any of which may use pre-arranged trading plans that are designed to meet the requirements of Rule 10b5-1(c) of the Securities Exchange Act of 1934 (“Exchange Act”). The timing of any repurchases and the actual number of shares repurchased will depend on a variety of factors, including our stock price, corporate and regulatory requirements, tax implications, restrictions under our debt obligations, other uses for capital, impacts on the value of remaining shares, cash generated from operations, and market and economic conditions.
Effective January 1, 2023, our repurchase of common stock, adjusted for allowable items, are subject to a 1% excise tax as a result of the Inflation Reduction Act of 2022. Excise taxes incurred on share repurchases of an entity’s own common stock are direct and incremental costs to purchase treasury stock, and accordingly are included in the total cost basis of the common stock acquired and reflected as a reduction of stockholders’ equity within “Treasury shares” in our Consolidated Balance Sheets and Consolidated Statements of Stockholders’ Deficit. Excise taxes do not reduce our remaining authorization for the repurchase of common stock. Excise taxes of $26 million and $25 million were accrued for shares repurchased during the year ended March 31, 2025 and 2024, respectively. On October 30, 2024, we made a payment of $25 million for fiscal 2024 excise taxes previously accrued. As of March 31, 2025 and March 31, 2024, the amount accrued for excise taxes was $26 million, and $25 million, respectively, within “Other accrued liabilities” in our Consolidated Balance Sheets.

(1)Based on year-end balances and sales or cost of sales for the last 90 days of the year.
(2)This ratio describes the relationship and changes within our capital resources, and is computed as the sum of total debt divided by the sum of total debt and McKesson stockholders’ deficit, which excludes noncontrolling interests and accumulated other comprehensive loss.
Cash equivalents, which are readily convertible to known amounts of cash, are carried at fair value. Cash equivalents are primarily invested in AAA-rated U.S. government money market funds, short-term deposits with financial institutions, and short-term commercial papers issued by non-financial institutions. Deposits with financial institutions are primarily denominated in U.S. dollars and the functional currencies of our foreign subsidiaries, including Canadian dollars. Deposits could exceed the amounts insured by the Federal Deposit Insurance Corporation in the U.S. and similar deposit insurance programs in other jurisdictions. We mitigate the risk of our short-term investment portfolio by depositing funds with reputable financial institutions and monitoring risk profiles and investment strategies of money market funds.

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
Our cash and cash equivalents balance as of March 31, 2025 and 2024 included approximately $2.9 billion and $1.6 billion, respectively, of cash held by our subsidiaries outside of the U.S. Our primary intent is to utilize this cash for foreign operations for an indefinite period of time. Although the majority of cash held outside the U.S. is available for repatriation, doing so could subject us to foreign withholding taxes and state income taxes. We may remit foreign earnings to the U.S. to the extent it is tax efficient to do so. We do not anticipate the tax impact from remitting these earnings to be material. Following enactment of the 2017 Tax Cuts and Jobs Act, the repatriation of cash to the U.S. is generally no longer taxable for federal income tax purposes.
Working capital primarily includes cash and cash equivalents, receivables, inventories, and prepaid expenses, net of drafts and accounts payable, short-term borrowings, current portion of long-term debt, current portion of operating lease liabilities, and other accrued liabilities. Our businesses require substantial investments in working capital that are susceptible to large variations during the year as a result of inventory purchase patterns and seasonal demands. Inventory purchase activity is a function of sales activity and other requirements.
Consolidated working capital decreased at March 31, 2025 compared to the prior year primarily due to an increase in drafts and accounts payable from increased purchasing driven by increased sales and timing, and an increase in the current portion of long-term debt. These were partially offset by an increase in receivables, net and inventories, net, driven by higher sales and timing, an increase in cash and cash equivalents, and a decrease in other accrued liabilities.
Our debt to capital ratio increased for the year ended March 31, 2025 compared to the prior year primarily due to share repurchases and dividend payments as well as repayments of long-term debt, partially offset by net income attributable to McKesson for the year and issuance of new long-term debt.
In July 2024, we raised our quarterly dividend from $0.62 to $0.71 per share of common stock for dividends declared on or after such date by the Board. Dividends were $2.75 per share in fiscal 2025 and $2.40 per share in fiscal 2024, and we paid total cash dividends of $345 million and $314 million in fiscal 2025 and fiscal 2024, respectively. We anticipate that we will continue to pay quarterly cash dividends in the future. However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon our future earnings, financial condition, capital requirements, legal requirements, and other factors.
Material Cash Requirements:
The table and information below presents our significant financial obligations and commitments as of March 31, 2025:

FINANCIAL REVIEW (Concluded)
(5)Primarily relates to the expected purchase of goods and services, including inventory and capital commitments, from vendors in the normal course of business.
(6)Includes agreements under which we have guaranteed the repurchase of our customers’ inventory and our customers’ debt in the event these customers are unable to meet their obligations to those financial institutions. Refer to Financial Note 16, “Financial Guarantees and Warranties,” to the consolidated financial statements included in this Annual Report for more information.
The material cash requirements table above excludes the following obligations:
At March 31, 2025, the Company had accrued liabilities of $6.4 billion related to the settlement of opioid-related litigation claims with U.S. governmental entities, including Native American tribes, and certain non-governmental plaintiffs as described in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual Report. The majority of this amount relates to governmental entities opioid settlement payable in annual installments through 2038 pursuant to the schedule set forth in the agreement. As of March 31, 2025, $776 million is estimated to be paid within the next twelve months.
At March 31, 2025, the liability recorded for uncertain tax positions, excluding associated interest and penalties, was approximately $1.1 billion. The ultimate amount and timing of any related future cash settlements cannot be predicted with reasonable certainty. Refer to Financial Note 6, “Income Taxes,” to the consolidated financial statements included in this Annual Report for additional information on income tax matters.
At March 31, 2025, our banks and insurance companies have issued $206 million of standby letters of credit and surety bonds. These were issued on our behalf and are mostly related to our customer contracts and to meet the security requirements for statutory licenses and permits, court and fiduciary obligations, pension obligations in Europe, and our workers’ compensation and automotive liability programs.
Capital Resources
We fund our working capital requirements primarily with cash and cash equivalents, proceeds from short-term borrowings from our commercial paper issuances, and longer-term credit agreements and debt offerings. Funds necessary for future debt maturities and our other cash requirements, including any future payments that may be made related to our total estimated litigation liability of $6.4 billion as of March 31, 2025 payable under the terms of various settlement agreements for opioid-related claims, are expected to be met by existing cash balances, cash flow from operations, existing credit sources, and future borrowings. Long-term debt markets and commercial paper markets, our primary sources of capital after cash flow from operations, are open and accessible to us should we decide to access those markets. Detailed information regarding our debt and financing activities is included in Financial Note 11, “Debt and Financing Activities,” to the consolidated financial statements included in this Annual Report.
We believe that our future operating cash flow, financial assets, and access to capital and credit markets, including our credit facilities, give us the ability to meet our financing needs for the foreseeable future. However, there can be no assurance that an increase in volatility or disruption in the global capital and credit markets will not impair our liquidity or increase our costs of borrowing.
RELATED PARTY BALANCES AND TRANSACTIONS
Information regarding our related party balances and transactions is included in Financial Note 19, “Related Party Balances and Transactions,” to the consolidated financial statements included in this Annual Report.
NEW ACCOUNTING PRONOUNCEMENTS
New accounting pronouncements that we have recently adopted, as well as those that have been recently issued but not yet adopted by us, are included in Financial Note 1, “Significant Accounting Policies,” to the consolidated financial statements included in this Annual Report.

McKESSON CORPORATION
Item 7A. Quantitative and Qualitative Disclosures about Market Risk.
Interest rate risk: Our long-term debt bears interest predominately at fixed rates, whereas our short-term borrowings are at variable interest rates. Our cash and cash equivalents balances earn interest at variable rates. At March 31, 2025 and 2024, we had $5.7 billion and $4.6 billion, respectively, in cash and cash equivalents. At March 31, 2025 and 2024, we also had fixed-to-floating interest rate swaps with a total notional amount of $750 million and $1.3 billion, respectively. The effect of a hypothetical 50 basis points increase in the underlying interest rate on our cash and cash equivalents, net of short-term borrowings and fixed-to-floating interest rate swaps, would have resulted in a favorable impact of $8 million and $4 million to our earnings in fiscal 2025 and fiscal 2024, respectively.
Foreign currency exchange rate risk: We conduct our business worldwide in U.S. dollars and the functional currencies of our foreign subsidiaries, primarily the Canadian dollar. We are also exposed to foreign currency exchange rate risk related to our foreign currency-denominated notes, intercompany loans denominated in non-functional currencies, and certain foreign subsidiaries, primarily the Euro, British pound sterling, and Canadian dollar. Changes in foreign currency exchange rates could have a material adverse impact on our financial results that are reported in U.S. dollars.
In September 2024, we announced an agreement to sell our Rexall and Well.ca businesses in Canada (“Canadian retail disposal group”). We completed the sale of the Canadian retail disposal group on December 30, 2024. In July 2021, we announced our intention to exit our businesses in Europe and completed the divestitures of our Austrian business in fiscal 2022, and the U.K. disposal group and the E.U. disposal group in fiscal 2023. Refer to Financial Note 2, “Business Acquisitions and Divestitures,” to the consolidated financial statements included in this Annual Report for more information on these divestitures. The completion of these divestitures has reduced our foreign currency exchange rate risk as it relates to the Euro and British pound sterling.
We have certain foreign currency exchange rate risk programs that utilize cross-currency swaps which are intended to reduce the income statement effects from fluctuations in foreign currency exchange rates and have been designated as net investment hedges, fair value hedges, or cash flow hedges. These programs reduce but do not entirely eliminate foreign currency exchange rate risk. However, our risk management programs are designed such that changes in the value of the underlying exposure would be largely offset by the potential changes in the value of the risk management portfolios. Refer to Financial Note 14, “Hedging Activities,” to the consolidated financial statements included in this Annual Report for more information on our cross-currency swaps.
The Company and its subsidiaries are periodically exposed to balances denominated in currencies other than their functional currency. At March 31, 2025 and 2024, the effect of a hypothetical adverse 10% change in the foreign currency exchange rates on underlying balances not reported in the functional currencies of the Company and these subsidiaries would not have resulted in a material impact to our earnings in fiscal 2025 or fiscal 2024. Refer to Financial Note 1, “Significant Accounting Policies,” under the section “Foreign Currency Translation” for more information regarding our exposure to transactional gains and losses.

McKESSON CORPORATION
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of McKesson Corporation
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of McKesson Corporation and subsidiaries (the "Company") as of March 31, 2025, and 2024, the related consolidated statements of operations, comprehensive income, stockholders’ equity (deficit), and cash flows, for each of the three years in the period ended March 31, 2025, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of March 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of March 31, 2025, and 2024, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2025, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
Basis for Opinions
The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

McKESSON CORPORATION
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Uncertain Tax Position, Opioid-Related Claims - refer to Note 1 and Note 6 to the financial statements
Critical Audit Matter Description
The Company has recorded charges and related tax benefit for opioid-related claims. In order to account for the uncertainty associated with the ultimate realization of the income tax benefit related to opioid-related claims, the Company recorded an uncertain tax position reserve. Tax benefits from uncertain tax positions are recognized when, based upon the technical tax merits, it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes. The net amount of income tax benefit recognized by management is measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized. The Company uses significant judgment in evaluating the technical tax merits of income tax benefits that qualify for recognition, including the determination of the amount that is more likely than not of being realized for U.S. federal and state income tax purposes.
We identified the Company’s uncertain tax position related to liabilities arising from opioid-related claims as a critical audit matter because of the challenges in auditing management’s estimate of the amount of income tax benefit that qualifies for recognition. Specifically, there is significant judgment associated with the assessment of the technical tax merits, including the related interpretation of applicable tax laws and regulations. Auditing the uncertain tax position related to liabilities arising from opioid-related claims required a high degree of auditor judgment and an increased extent of effort, including the need to involve our tax specialists.

Table of Contents | Item 8 Index

McKESSON CORPORATION
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the Company’s uncertain tax position associated with liabilities arising from opioid-related claims included the following, among others:
•We tested the effectiveness of the Company’s internal control related to management’s assessment of the technical merits of its tax position and the amount of benefit more likely than not to be realized related to liabilities arising from opioid-related claims.
•With the assistance of our income tax specialists, we evaluated the facts, evidence and the Company’s related income tax analysis for the uncertain tax position reserve associated with liabilities arising from opioid-related claims.
•We held inquiries with the Company’s internal and external income tax specialists related to the uncertain tax position for liabilities arising from opioid-related claims.
•We evaluated any events after March 31, 2025, that might affect management’s accounting treatment and related applicable disclosures.
•We obtained written representations from executives and internal legal counsel of the Company.
•We obtained and reviewed terms related to the Company’s settlements of opioid-related claims and evaluated them against the deductibility criteria set forth by relevant tax laws and regulations.
•We evaluated the Company’s related disclosures for consistency with our testing and also searched for contradictory evidence by reading disclosures from peer companies, who are also party to opioid-related litigation.

McKESSON CORPORATION
FINANCIAL NOTES
1. Significant Accounting Policies
Nature of Operations: McKesson Corporation together with its subsidiaries (collectively, the “Company” or “McKesson”) is a diversified healthcare services leader dedicated to advancing health outcomes for patients everywhere. McKesson partners with biopharma companies, care providers, pharmacies, manufacturers, governments, and others to deliver insights, products, and services to help make quality care more accessible and affordable. The Company reports its financial results in four reportable segments: U.S. Pharmaceutical, Prescription Technology Solutions (“RxTS”), Medical-Surgical Solutions, and International. Refer to Financial Note 20, “Segments of Business,” for additional information.
Basis of Presentation: The consolidated financial statements and accompanying notes are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The consolidated financial statements of McKesson include the financial statements of all majority-owned or controlled companies. For those consolidated subsidiaries where the Company’s ownership is less than 100%, the portion of the net income or loss allocable to the noncontrolling interests is reported as “Net income attributable to noncontrolling interests” in the Consolidated Statements of Operations. All significant intercompany balances and transactions have been eliminated in consolidation, including the intercompany portion of transactions with equity method investees.
The Company considers itself to control an entity if it is the majority owner of or has voting control over such entity. The Company also assesses control through means other than voting rights and determines which business entity is the primary beneficiary of the variable interest entity (“VIE”). The Company consolidates VIEs when it is determined that it is the primary beneficiary of the VIE. Investments in business entities in which the Company does not have control, but instead has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method.
Fiscal Period: The Company’s fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, all references to a particular year shall mean the Company’s fiscal year.
Reclassifications: Certain prior period amounts have been reclassified to conform to the current year presentation.
Use of Estimates: The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual amounts could differ from those estimated amounts.
Cash and Cash Equivalents: All highly liquid debt and money market instruments purchased with an original maturity of three months or less at the date of acquisition are included in cash and cash equivalents. Cash equivalents are carried at fair value. Cash equivalents are primarily invested in AAA-rated U.S. government money market funds, short-term deposits with financial institutions, and short-term commercial papers issued by non-financial institutions. Deposits with financial institutions are primarily denominated in U.S. dollars and the functional currencies of the Company’s foreign subsidiaries, including Canadian dollars, Euro, and British pounds sterling. Deposits could exceed the amounts insured by the Federal Deposit Insurance Corporation in the U.S. and similar deposit insurance programs in other jurisdictions. The Company mitigates the risk of its short-term investment portfolio by depositing funds with reputable financial institutions and monitoring risk profiles and investment strategies of money market funds.
Restricted Cash: Cash that is subject to legal restrictions or is unavailable for general operating purposes is classified as restricted cash and is included in “Prepaid expenses and other” and “Other non-current assets” in the Consolidated Balance Sheets.
Equity Method Investments: Investments in business entities in which the Company does not have control, but instead has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method. The Company evaluates its equity method investments for impairment whenever an event or change in circumstances occurs that could have a significant adverse impact on the carrying value of the investment. If a loss in value has occurred that is deemed to be other-than-temporary, an impairment loss is recorded.
Receivables, Net and Allowances for Credit Losses: The Company’s receivables are presented net of an allowance for credit losses and primarily consist of trade accounts receivable from customers that result from the sale of goods and services. Receivables, net also includes other receivables, which primarily represent amounts due from suppliers.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
The Company is exposed to credit losses on accounts receivable balances. The Company estimates credit losses by considering historical credit losses, the current economic environment, customer credit ratings, collections on past due amounts, legal disputes, and bankruptcies, as well as reasonable and supportable forecasts to develop its allowance for credit losses. Management reviews these factors quarterly to determine if any adjustments are needed to the allowance.
Trade accounts receivable represent the majority of the Company's financial assets, for which an allowance for credit losses of $450 million and $864 million were included in “Receivables, net” in the Consolidated Balance Sheets as of March 31, 2025 and 2024, respectively. The increase in the allowance for the year ended March 31, 2024 was primarily due to a provision for bad debts recognized of $725 million related to the bankruptcy of the Company’s customer Rite Aid Corporation (including certain of its subsidiaries, “Rite Aid”). In October 2023, Rite Aid filed a voluntary petition for reorganization under Chapter 11 of the Bankruptcy Code and this amount represents the uncollected trade accounts receivable balance due from Rite Aid prior to its bankruptcy petition filing. During the year ended March 31, 2025, the Company reassessed its initial estimates made in conjunction with the previously reserved prepetition balances, including cash received during the period, resulting in a reversal of $206 million recorded within “Selling, distribution, general, and administrative expenses” in the Company’s Consolidated Statements of Operations and included within the U.S. Pharmaceutical segment. During the year ended March 31, 2025, the Company released $237 million of allowance for doubtful accounts against trade accounts receivables, representing the write-off of uncollectible receivables related to the Rite Aid provision in the Consolidated Balance Sheet.
The following table presents the components of the Company’s receivables as of March 31, 2025 and 2024:

| March 31,
(In millions) | 2025 |  | 2024
Customer accounts | $ | 22,281 |  |  | $ | 19,439 |
Other | 3,862 |  |  | 3,104 |
Total receivables | 26,143 |  |  | 22,543 |
Allowances | (500) |  |  | (921) |
Receivables, net | $ | 25,643 |  |  | $ | 21,622 |

Concentrations of Credit Risk and Receivables: The Company’s trade accounts receivable are subject to concentrations of credit risk with customers primarily in its U.S. Pharmaceutical segment. During fiscal 2025, sales to the Company’s ten largest customers, including group purchasing organizations (“GPOs”), accounted for approximately 72% of its total consolidated revenues and approximately 48% of total trade accounts receivable at March 31, 2025. Sales to the Company’s largest customer, CVS Health Corporation (“CVS”), accounted for approximately 24% of its total consolidated revenues in fiscal 2025 and comprised approximately 23% of total trade accounts receivable at March 31, 2025. As a result, the Company’s sales and credit concentration is significant. The Company has agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies, and other healthcare providers, as well as with government entities and agencies. The accounts receivable balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. A material default in payment, a material reduction in purchases from GPOs or any other large customers, or the loss of a large customer or customer groups could have a material adverse impact on the Company’s financial condition, results of operations, and liquidity. In addition, trade accounts receivables are subject to concentrations of credit risk with customers in the institutional, retail, and healthcare provider sectors, which can be affected by a downturn in the economy, changes in reimbursement policies, and other factors. This credit risk is mitigated by the size and diversity of the Company’s customer base as well as its geographic dispersion.
Inventories: Inventories consist of merchandise held for resale. The Company reports inventories at the lower of cost or net realizable value, except for inventories determined using the last-in, first-out (“LIFO”) method which are valued at the lower of LIFO cost or market. The LIFO method presumes that the most recent inventory purchases are the first items sold and the inventory cost under LIFO approximates market. The majority of the cost of domestic inventories is determined using the LIFO method. The majority of the cost of inventories held in foreign and certain domestic locations is based on the first-in, first-out (“FIFO”) method or weighted-average purchase prices. Rebates, cash discounts, and other incentives received from vendors are recognized in cost of sales upon the sale of the related inventory.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
At March 31, 2025 and 2024, total inventories, net were $23.0 billion and $21.1 billion, respectively, in the Company’s Consolidated Balance Sheets. The LIFO method was used to value approximately 63% and 62% of the Company’s inventories at March 31, 2025 and 2024, respectively. If the Company had used the moving average method of inventory valuation, inventories would have been approximately $309 million and $227 million higher than the amounts reported at March 31, 2025 and 2024, respectively. These amounts are equivalent to the Company’s LIFO reserves. A LIFO charge is recognized when the net effect of price increases on pharmaceutical and non-pharmaceutical products held in inventory exceeds the impact of price declines, including the effect of branded pharmaceutical products that have lost market exclusivity. A LIFO credit is recognized when the net effect of price declines exceeds the impact of price increases on pharmaceutical and non-pharmaceutical products held in inventory. The Company recognized a LIFO charge of $82 million in fiscal 2025, a LIFO credit of $157 million in fiscal 2024, and a LIFO charge of $1 million in fiscal 2023, all within “Cost of sales” in its Consolidated Statements of Operations. The LIFO charge in fiscal 2025 compared to a LIFO credit in fiscal 2024 was primarily due to higher brand inflation in the current fiscal year. The LIFO credit in fiscal 2024 compared to a LIFO charge in fiscal 2023 was primarily due to lower brand inflation, offset by higher brand inventory levels, lower deflation from off patent launch activity, and lower generics deflation. The Company’s LIFO valuation amount includes both pharmaceutical and non-pharmaceutical products.
The Company believes that the moving average inventory costing method provides a reasonable estimation of the current cost of replacing inventory (i.e., “market”). As such, its LIFO inventory is valued at the lower of LIFO cost or market. As of March 31, 2025 and 2024, inventories at LIFO did not exceed market.
Shipping and Handling Costs: The Company includes costs to pack and deliver inventory to its customers in “Selling, distribution, general, and administrative expenses” in its Consolidated Statements of Operations. Shipping and handling costs of $1.1 billion, $1.1 billion, and $1.2 billion were recognized in fiscal 2025, fiscal 2024, and fiscal 2023, respectively.
Held for Sale: Assets and liabilities to be disposed of by sale (“disposal groups”) are classified as “held for sale” if their carrying amounts are principally expected to be recovered through a sale transaction rather than through continuing use. The classification occurs when the disposal group is available for immediate sale and the sale is probable. These criteria are generally met when management has committed to a plan to sell the assets within one year. Disposal groups are measured at the lower of carrying amount or fair value less costs to sell, and long-lived assets included within the disposal group are not depreciated or amortized. The fair value of a disposal group, less any costs to sell, is assessed during each reporting period it remains classified as held for sale, and any remeasurement to the lower of carrying value or fair value less costs to sell is reported as an adjustment to the carrying value of the disposal group. When the net realizable value of a disposal group increases during a period, a gain can be recognized to the extent that it does not increase the value of the disposal group beyond its original carrying value when the disposal group was reclassified as held for sale. Refer to Financial Note 2, “Business Acquisitions and Divestitures,” for additional information.
Property, Plant, and Equipment, Net: Property, plant, and equipment, net is stated at historical cost and depreciated under the straight-line method over the estimated useful life of each asset, which ranges from 15 to 30 years for building and improvements and three to 15 years for machinery, equipment, and other. Leasehold improvements and property, plant, and equipment, net under finance leases are amortized over their respective useful lives of the right-of-use (“ROU”) asset or over the term of the lease, whichever is shorter. Depreciation and amortization begins when an asset is placed in service and ready for its intended use. Repairs and maintenance costs are expensed as incurred. When certain events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable, an impairment assessment may be performed on the recoverability of the carrying amounts.

The following table presents the components of the Company’s property, plant, and equipment, net as of March 31, 2025 and 2024:

| March 31,
(In millions) | 2025 |  | 2024
Land | $ | 104 |  |  | $ | 109 |
Building and improvements | 1,433 |  |  | 1,482 |

Construction in progress | 722 |  |  | 441 |
Total property, plant, and equipment | 5,031 |  |  | 4,783 |
Accumulated depreciation and amortization | (2,529) |  |  | (2,467) |
Property, plant, and equipment, net | $ | 2,502 |  |  | $ | 2,316 |

Total depreciation expense for property, plant, and equipment, net and amortization of the ROU assets of finance leases was $272 million, $279 million, and $272 million for the years ended March 31, 2025, 2024, and 2023, respectively.
Leases: The Company leases facilities and equipment primarily under operating leases. The Company recognizes lease expense on a straight-line basis over the term of the lease, taking into account, when applicable, lessor incentives for tenant improvements, periods where no rent payment is required, and escalations in rent payments over the term of the lease. As a practical expedient, the Company does not separate lease components from non-lease components, such as common area maintenance, utilities, and repairs and maintenance. Remaining terms for facility leases generally range from one to 15 years, while remaining terms for equipment leases generally range from one to five years. Most real property leases contain renewal options (typically for five-year increments). Generally, the renewal option periods are not included within the lease term as the Company is not reasonably certain to exercise that right at lease commencement. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Operating ROU assets and operating lease liabilities are recognized at the lease commencement date. ROU assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease liabilities are recognized based on the present value of the future lease payments over the lease term, discounted at the Company’s incremental borrowing rate as the implicit rate in the lease is not readily determinable for most of the Company’s leases. The Company estimates the discount rate as its incremental borrowing rate based on qualitative factors including Company specific credit rating, lease term, general economics, and the interest rate environment. Operating lease liabilities are recorded in “Current portion of operating lease liabilities” and “Long-term operating lease liabilities,” and the corresponding lease assets are recorded in “Operating lease right-of-use assets” in the Company’s Consolidated Balance Sheets. Finance lease assets are included in “Property, plant, and equipment, net” and finance lease liabilities are included in “Current portion of long-term debt” and “Long-term debt” in the Company’s Consolidated Balance Sheets. As a practical expedient, short-term leases with an initial term of 12 months or less are excluded from the Consolidated Balance Sheets and charges from these leases are expensed as incurred.
As a lessor, the Company primarily leases certain owned equipment, classified as direct financing or sales-type leases, to physician practices.
Refer to Financial Note 9, “Leases,” for additional information on the Company’s leases.
Goodwill: Goodwill is tested for impairment on an annual basis in the first fiscal quarter and more frequently if indicators of potential impairment exist. Impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or one level below an operating segment (also known as a component), for which discrete financial information is available and segment management regularly reviews the operating results.
The Company applies the goodwill impairment test by comparing the estimated fair value of a reporting unit to its carrying value and recording an impairment charge equal to the amount of excess carrying value above the estimated fair value, if any, but not to exceed the amount of goodwill allocated to the reporting unit.

FINANCIAL NOTES (Continued)
To estimate the fair value of its reporting units, the Company generally uses a combination of the market approach and the income approach. Under the market approach, it estimates fair value by comparing the business to similar businesses, or guideline companies whose securities are actively traded in public markets. Under the income approach, it uses a discounted cash flow (“DCF”) model in which cash flows anticipated over future periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate that is commensurate with the risk inherent within the reporting unit. Other estimates inherent in both the market and income approaches include long-term growth rates, projected revenues, and earnings and cash flow forecasts for the reporting units. In addition, the Company compares the aggregate of the reporting units’ fair values to the Company’s market capitalization as further corroboration of the fair values. Goodwill testing requires a complex series of assumptions and judgments by management in projecting future operating results, selecting guideline public companies for comparisons, and assessing risks. The use of alternative assumptions and estimates could affect the fair values and change the impairment determinations.
Intangible Assets: Currently all of the Company’s identifiable intangible assets are subject to amortization and are amortized based on the pattern of their economic consumption or on a straight-line basis over their estimated useful lives, ranging from one to 25 years. The Company reviews intangible assets for impairment at an asset group level whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated future undiscounted cash flows resulting from the use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset group over its estimated fair value. The Company also performs a periodic review of its intangible assets and removes from the balance sheet fully amortized intangible assets that no longer provide an economic benefit, are no longer in use, or for which the related contract has expired. During the year ended March 31, 2024, the Company removed from the balance sheet $1.4 billion of fully amortized gross intangible assets and the corresponding accumulated amortization.
Capitalized Software Held for Internal Use: The Company capitalizes costs of software held for internal use during the application development stage of a project and amortizes those costs using the straight-line method over their estimated useful lives, not to exceed 10 years. As of March 31, 2025 and 2024, capitalized software held for internal use was $681 million and $495 million, respectively, net of accumulated amortization of $657 million and $560 million, respectively, and is included in “Other non-current assets” in the Consolidated Balance Sheets. Costs incurred during the preliminary project and post-implementation stages are expensed as incurred. Amortization expense for capitalized software held for internal use was $135 million, $102 million, and $101 million for the years ended March 31, 2025, 2024, and 2023, respectively. The Company performs a periodic review of its capitalized software held for internal use and removes from the balance sheet fully amortized capitalized software costs that are determined to no longer be in use. During the year ended year ended March 31, 2024, the Company removed from the balance sheet $1.0 billion of fully amortized gross capitalized software held for internal use and the corresponding accumulated amortization.
Insurance Programs: The Company maintains insurance programs through its wholly-owned captive insurance subsidiaries (“Captives”) from which it obtains coverage for various exposures, including certain exposures arising from the opioid-related claims of governmental entities against the Company as discussed in more detail in Financial Note 17, “Commitments and Contingent Liabilities,” as well as those risks required to be insured by law or contract. It is the Company’s policy to retain a significant portion of certain losses, including those related to workers’ compensation and comprehensive general, product, and vehicle liability. Provisions for losses expected under insurance programs are recorded based on the Company’s estimate of the aggregate liability for claims incurred as well as for claims incurred but not yet reported. Such estimates utilize certain actuarial assumptions followed in the insurance industry. The Captives receive direct premiums, which are eliminated on consolidation against the Company’s premium costs within “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations.
Revenue Recognition: Revenue is recognized when an entity satisfies a performance obligation by transferring control of a promised good or service to a customer in an amount that reflects the consideration to which the entity expects to be entitled for that good or service.

FINANCIAL NOTES (Continued)
Revenues generated from the distribution of pharmaceutical and medical products represent the majority of the Company’s revenues. The Company orders product from the manufacturer, receives and carries the product at its central distribution facilities, and delivers the product directly to its customers’ warehouses, hospitals, or retail pharmacies. The distribution business primarily generates revenue from a contract related to a confirmed purchase order with a customer in a distribution arrangement. Revenue is recognized when control of goods is transferred to the customer which occurs upon the Company’s delivery to the customer or upon customer pick-up. The Company also earns revenues from a variety of other sources including its retail, services, and technology businesses. Retail revenues are recognized at the point of sale. Service revenues, including technology service revenues, are recognized when services are rendered. Revenues derived from distribution and retail business at the point of sale represent approximately 99%, 98%, and 99% of total revenues for the years ended March 31, 2025, 2024, and 2023, respectively. Revenues derived from services represent approximately 1%, 2%, and 1% of total revenues for the years ended March 31, 2025, 2024, and 2023, respectively.
Revenues are recorded gross when the Company is the principal in the transaction, has the ability to direct the use of the goods or services prior to transfer to a customer, is responsible for fulfilling the promise to its customer, has latitude in establishing prices, and controls the relationship with the customer. The Company records its revenues net of sales taxes. Revenues are measured based on the amount of consideration that the Company expects to receive, reduced by estimates for return allowances, discounts, and rebates using historical data. Sales returns from customers were approximately $2.9 billion, $3.0 billion, and $3.1 billion for the years ended March 31, 2025, 2024, and 2023, respectively. Assets for the right to recover products from customers and the associated refund liabilities for return allowances were not material as of March 31, 2025 and 2024. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs. The Company records deferred revenues when payments are received or due in advance of its performance. Deferred revenues are primarily from the Company’s services arrangements and are recognized as revenues over the periods when services are performed.
The Company had no material contract assets, contract liabilities, or deferred contract costs recorded in its Consolidated Balance Sheets as of March 31, 2025 and 2024. The Company generally expenses costs to obtain a contract as incurred when the amortization period is less than one year.
Supplier Incentives: Fees for services and other incentives received from suppliers, relating to the purchase or distribution of inventory, are considered product discounts and are generally reported as a reduction to cost of sales.
Supplier Reserves: The Company establishes reserves against amounts due from suppliers relating to various fees for services and price and rebate incentives, including deductions taken against payments otherwise due to it. These reserve estimates are established based on judgment after considering the status of current outstanding claims, historical experience with the suppliers, the specific incentive programs, and any other pertinent information available. The Company evaluates the amounts due from suppliers on a continual basis and adjusts the reserve estimates when appropriate based on changes in facts and circumstances. Adjustments to supplier reserves are generally included in cost of sales unless consideration from the vendor is in exchange for distinct goods or services or for pass-through rebate purchases. The ultimate outcome of any outstanding claims could be different than the Company’s estimate. The supplier reserves primarily pertain to the Company’s U.S. Pharmaceutical segment.
Income Taxes: The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or the tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statements and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Tax benefits from uncertain tax positions are recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. The amount recognized is measured as the largest amount of tax benefit that is greater than 50% likely of being realized.
Interest Expense: Interest expense primarily includes interest for the Company’s long-term debt obligations, commercial paper, net interest settlements of interest rate swaps, and the amortization of deferred issuance costs and original issue discounts on debt.

FINANCIAL NOTES (Continued)
Foreign Currency Translation: The reporting currency of the Company and its subsidiaries is the U.S. dollar. Its foreign subsidiaries generally consider their local currency to be their functional currency. Foreign currency-denominated assets and liabilities of these foreign subsidiaries are translated into U.S. dollars at period-end exchange rates, while revenues and expenses are translated at average exchange rates during the corresponding period and stockholders’ equity or deficit accounts are primarily translated at historical exchange rates. Foreign currency translation adjustments are included in “Other comprehensive income (loss), net of tax” in the Consolidated Statements of Comprehensive Income, and the cumulative effect is included in the stockholders’ deficit section of the Consolidated Balance Sheets. Gains and losses from currency exchange transactions are recorded in “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations and were not material for the years ended March 31, 2025, 2024, and 2023. The Company releases cumulative translation adjustments from stockholders’ equity or deficit into earnings as a gain or loss only upon a complete or substantially complete liquidation of a controlling interest in a subsidiary or a group of assets within a foreign entity. It also releases all or a pro-rata portion of the cumulative translation adjustments into earnings upon the sale of an equity method investment that is a foreign entity or has a foreign component.
Derivative Financial Instruments: Derivative financial instruments are used principally in the management of foreign currency exchange and interest rate exposures and are recorded in the Consolidated Balance Sheets at fair value. The Company uses cross-currency swaps to hedge the changes in the fair value of its foreign currency notes resulting from changes in benchmark interest rates and foreign currency exchange rates. The Company also uses floating interest rate swaps to hedge the changes in the fair value of its U.S. dollar notes resulting from changes in benchmark interest rates. If a derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. The Company has used foreign currency-denominated notes and uses cross-currency swaps to hedge a portion of its net investment in its foreign subsidiaries. The Company uses cash flow hedges primarily to reduce the effects of foreign currency exchange rate risk related to intercompany loans denominated in non-functional currencies. The Company also uses forward contracts to hedge the variability of future benchmark interest rates on any planned bond issuances and to offset the potential income statement effects from obligations denominated in non-functional currencies. If the financial instrument is designated as a cash flow hedge or net investment hedge, the effective portions of changes in the fair value of the derivative are included in “Other comprehensive income (loss), net of tax” in the Consolidated Statements of Comprehensive Income, and the cumulative effect is included in the stockholders’ deficit section of the Consolidated Balance Sheets. The cumulative changes in fair value are reclassified to the same line as the hedged item in the Consolidated Statements of Operations when the hedged item affects earnings. The Company evaluates hedge effectiveness at inception and on an ongoing basis, and ineffective portions of changes in the fair value of cash flow hedges and net investment hedges are recognized in earnings following the date when ineffectiveness was identified. Any cash flows received or paid as part of the termination of derivative financial instruments are classified within the Consolidated Statements of Cash Flows in accordance with the nature of the hedged item. Derivative instruments not designated as hedges are marked-to-market at the end of each accounting period with the change included in earnings. Refer to Financial Note 14, “Hedging Activities,” for additional information.
Comprehensive Income: Comprehensive income consists of two components: net income and other comprehensive income or loss. Other comprehensive income or loss refers to revenue, expenses, as well as gains and losses that are recorded as an element of stockholders’ deficit but are excluded from earnings. The Company’s other comprehensive income or loss primarily consists of foreign currency translation adjustments from those subsidiaries where the local currency is the functional currency, including gains and losses on net investment hedges, as well as unrealized gains and losses on cash flow hedges and unrealized gains and losses on retirement-related benefit plans.
Noncontrolling Interests: Noncontrolling interests represent the portion of profit or loss, net assets, and comprehensive income or loss that is not allocable to McKesson Corporation. Net income attributable to noncontrolling interests includes third-party equity interests in the Company’s consolidated entities, including: ClarusONE Sourcing Services LLP (“ClarusONE”), a joint venture established between McKesson and Walmart Inc. in fiscal 2017; Vantage Oncology Holdings, LLC (“Vantage”), a provider of integrated oncology and radiation services acquired in fiscal 2017; and SCRI Oncology, LLC (“SCRI Oncology”), an oncology research business formed in fiscal 2023. Net income attributable to noncontrolling interests also included recurring compensation that the Company was obligated to pay to the noncontrolling shareholders of McKesson Europe AG (“McKesson Europe”), formerly known as Celesio AG, under the domination and profit and loss transfer agreement. The Company’s noncontrolling interest in McKesson Europe was included in the divestiture of certain of the Company’s businesses in the European Union (“E.U.”) in October 2022.

FINANCIAL NOTES (Continued)
Share-Based Compensation: The Company accounts for all share-based compensation transactions at fair value. The share-based compensation expense, for the portion of the awards that is ultimately expected to vest, is recognized on a straight-line basis over the requisite service period. The Company estimates the number of share-based awards that will ultimately vest primarily based on historical experience. The estimated forfeiture rate established upon grant is re-assessed throughout the requisite service period and is adjusted when actual forfeitures occur. The actual forfeitures in future reporting periods could be higher or lower than current estimates. The share-based compensation expense recognized is classified in the Consolidated Statements of Operations in the same manner as cash compensation paid to the Company’s employees and included in “Selling, distribution, general, and administrative expenses.” Refer to Financial Note 4, “Share-Based Compensation,” for additional information.
Loss Contingencies: The Company is subject to various claims, including, but not limited to, claims with customers and vendors, pending and potential legal actions for damages, investigations relating to governmental laws and regulations, and other matters arising out of the normal conduct of its business. When a loss is considered probable and reasonably estimable, the Company records a liability in the amount of its best estimate for the ultimate loss. However, the likelihood of a loss with respect to a particular contingency is often difficult to predict and determining a meaningful estimate of the loss or a range of loss may not be practicable based on the information available and the potential effect of future events and decisions by third parties that will determine the ultimate resolution of the contingency. Moreover, it is not uncommon for such matters to be resolved over many years, during which time relevant developments and new information must be reevaluated at least quarterly to determine both the likelihood of potential loss and whether it is possible to reasonably estimate the loss or a range of possible loss. When a material loss is reasonably possible, or probable but a reasonable estimate cannot be made, disclosure of the proceeding is provided. The Company expenses legal fees as incurred when the legal services are provided.
The Company reviews all material contingencies at least quarterly to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or a range of the loss can be made. As discussed above, development of a meaningful estimate of loss or a range of potential loss is complex when the outcome is directly dependent on negotiations with or decisions by third parties, such as regulatory agencies, the court system, and other interested parties. Refer to Financial Note 17, “Commitments and Contingent Liabilities,” f or additional information related to controlled substances claims to which the Company is a party.
Restructuring Charges: Restructuring charges are incurred for programs in which the Company changes its operations, the scope of a business undertaken by its business units, or the manner in which that business is conducted as well as long-lived asset impairments. Such charges may include employee severance, retention bonuses, facility closure or consolidation costs, lease or contract termination costs, asset impairments, accelerated depreciation and amortization, and other related expenses. The restructuring programs may be implemented due to the sale or discontinuation of a product line, reorganization or management structure changes, headcount rationalization, realignment of operations or products, integration of acquired businesses, and/or company-wide cost saving initiatives. The amount and/or frequency of these restructuring charges are not part of the Company’s underlying business, which include normal levels of reinvestment in the business. Employee severance costs are generally recognized when payments are probable and amounts are reasonably estimable. Costs related to contracts without future benefit or contract termination are recognized at fair value at the earlier of the contract termination or the cease-use dates. Other exit-related costs are expensed as incurred. Restructuring charges may also include credit adjustments due to subsequent changes in estimates. Refer to Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” for additional information.
Business Combinations: The Company accounts for business combinations using the acquisition method of accounting whereby the identifiable assets and liabilities of the acquired business, including contingent consideration, as well as any noncontrolling interest in the acquired business, are recorded at their estimated fair values as of the date that the Company obtains control of the acquired business. Any purchase consideration in excess of the estimated fair values of the net assets acquired is recorded as goodwill. Acquisition-related expenses and related restructuring costs are expensed as incurred.
Several valuation methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, the Company typically uses a variation of the income approach, whereby a forecast of future cash flows attributable to the asset is discounted to present value using a risk-adjusted discount rate. Some of the more significant estimates and assumptions inherent in the income approach include the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows, and the assessment of the asset’s expected useful life.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
Contingent consideration liabilities are measured at their fair value as of the acquisition date using unobservable inputs. These inputs include the estimated amount and timing of projected operational and financial information, the probability of achievement of performance milestones or other agreed-upon events, and the risk-adjusted discount rate used to calculate the present value of the probability-weighted projected financial information. Contingent liabilities are remeasured to fair value at each reporting date until the liability is resolved. Changes in any of the inputs could result in a significant adjustment to the fair value.
Treasury Stock: The Company records purchases of treasury stock at cost, which is reflected as a reduction to stockholders’ equity in the Company’s Consolidated Balance Sheets. Incremental direct costs to purchase treasury stock, including any excise tax recognized as a result of the IRA, are included in the cost of the shares acquired. Treasury stock also includes shares withheld to satisfy the tax obligations of recipients of share-based compensation. Refer to Financial Note 18, “Stockholders' Equity (Deficit)," for additional information.
Recently Adopted Accounting Pronouncements
In the fourth quarter of fiscal 2025, the Company adopted Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands reportable segment disclosures by requiring disclosure, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, as well as an amount and description of other segment items. The guidance also requires interim disclosures of a reportable segment’s profit or loss and assets, disclosure of the title and position of the CODM, and an explanation of how the CODM uses the reported measure of segment profit or loss in assessing performance and allocating resources. The adoption of this amended guidance resulted in changes in disclosures but did not have an impact on the Company’s Consolidated Statements of Operations, Comprehensive Income (Loss), Balance Sheets, or Cash Flows.
Recently Issued Accounting Pronouncements Not Yet Adopted
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosure s. ASU 2023-09 improves the transparency of income tax disclosures by requiring, on an annual basis, consistent categories, and greater disaggregation of information in the rate reconciliation as well as income taxes paid disaggregated by jurisdiction. The update is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments in this update should be applied prospectively, although optional retrospective application is permitted. While this accounting standard will increase disclosures related to the Company’s income taxes, it will not have a material impact on the Company’s Consolidated Financial Statement results.
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 requires disclosure of certain costs and expenses on an interim and annual basis in the notes to the financial statements. ASU 2024-03 is effective for the Company for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, as clarified by ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40). Early adoption is permitted. The Company is currently evaluating the impact that this guidance will have on its disclosures.
2. Business Acquisitions and Divestitures
Acquisitions
Rx Savings Solutions, LLC
On November 1, 2022, the Company completed its acquisition of 100% of the shares of Rx Savings Solutions, LLC (“RxSS”), a privately-owned company headquartered in Overland Park, Kansas, to further connect biopharma and payer services to patients. RxSS is a prescription price transparency and benefit insight company that offers affordability and adherence solutions to health plans and employers. The purchase consideration included a payment of $600 million in cash made upon closing and a maximum of $275 million of contingent consideration based on RxSS’ operational and financial performance through calendar year 2025. The payment made upon closing was funded from cash on hand. The financial results of RxSS are included in the Company’s RxTS segment as of the acquisition date. The transaction was accounted for as a business combination.

The Company recorded a liability for the contingent consideration at its fair value of $92 million as of the acquisition date. The fair value of the contingent consideration liability was estimated using a Monte Carlo simulation model, utilizing internal cash flow projections which are Level 3 inputs under Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures. The contingent consideration liability will be remeasured to fair value at each reporting date until the liability is settled with changes in fair value being recognized within “Selling, distribution, general, and administrative expenses” in the Company’s Consolidated Statements of Operations. During the year ended March 31, 2024, the Company recognized fair value adjustment gains of $78 million, which reduced its contingent consideration liability, based on the estimated amount and timing of projected operational and financial information and the probability of achievement of performance milestones. As of March 31, 2025 and 2024, the current portion of the contingent consideration liability of $14 million is included within “Other accrued liabilities.” Recognition of the initial fair value of this contingent consideration was a non-cash investing activity.
The purchase price allocation included acquired identifiable intangible assets of $229 million, primarily representing customer relationships and technology with a weighted average amortization period of 12 years, and goodwill of $463 million. Goodwill has been allocated to the Company’s RxTS segment, which reflects the expected future benefits from certain synergies and intangible assets that do not qualify for separate recognition. Goodwill attributable to the acquisition is deductible for tax purposes.
The following table summarizes the final purchase price allocation for this acquisition:

(In millions) | Amounts Recognized as of Acquisition Date (Final)
Purchase consideration: |
Cash | $ | 600 |
Contingent consideration | 92 |
Total purchase consideration | $ | 692 |
Identifiable assets acquired and liabilities assumed: |

SCRI Oncology, LLC
On October 31, 2022, the Company completed a transaction with HCA Healthcare, Inc. (“HCA”) to form SCRI Oncology, an oncology research business combining McKesson’s U.S. Oncology Research (“USOR”) and HCA’s Sarah Cannon Research Institute (“SCRI”) based in Nashville, Tennessee, to advance cancer care and increase access to oncology clinical research. McKesson owns a 51% controlling interest in the combined business, and the financial results are consolidated by the Company and reported within its U.S. Pharmaceutical segment as of the acquisition date. Transaction consideration included the transfer of full ownership interest in USOR to the combined business and $166 million of net cash paid to HCA, which was funded from cash on hand. The transaction was accounted for as a business combination.

Goodwill has been allocated to the Company’s U.S. Pharmaceutical segment, which reflects the expected future benefits from certain synergies and intangible assets that do not qualify for separate recognition. Goodwill attributable to the acquisition of $46 million is deductible for tax purposes. The Company recorded noncontrolling interest of $225 million as a component of equity, which includes HCA’s proportionate interest in the identifiable net assets of SCRI at fair value of $202 million and its proportionate interest in the contributed net assets of USOR at carrying value of $23 million. The difference between the fair value of the Company’s acquired interest in SCRI net assets and the $166 million of net cash paid to HCA was recognized as additional paid in capital, as well as the Company’s reduction in ownership interest in USOR net assets.
The following table summarizes the final purchase price allocation for this acquisition:

(In millions) | Amounts Recognized as of Acquisition Date (Final)
Purchase consideration: |
Cash | $ | 166 |
Contribution of USOR | 46 |
Total purchase consideration | $ | 212 |
Identifiable assets acquired and liabilities assumed: |
Receivables | $ | 224 |
Property, plant, and equipment | 22 |
Operating lease right-of-use assets | 31 |
Intangible assets | 177 |
Other non-current assets | 6 |
Current liabilities | (42) |
Long-term operating lease liabilities | (29) |
Other non-current liabilities | (43) |
Total identifiable net assets | 346 |
Noncontrolling interest | (225) |
Additional paid-in capital | (22) |
Goodwill | 113 |
Net assets acquired | $ | 212 |

The fair value of the acquired identifiable intangible assets from the acquisitions discussed above were determined by applying the income approach, using a discounted cash flow model in which cash flows anticipated over several periods are discounted to their present value using an appropriate rate that is commensurate with the risk inherent with the transaction. These inputs are considered Level 3 inputs under the fair value measurements and disclosure guidance. The Company’s fair value assessments of these acquisitions were finalized upon completion of the measurement period in the third quarter of fiscal 2024. There were no material changes to the purchase price allocations since the respective acquisition dates. Pro forma financial information has not been provided as these acquisitions did not have a material impact, individually, or in the aggregate, to the Company’s consolidated results of operations.

Divestitures
Canada Divestiture Activities
On December 30, 2024, the Company completed the sale of its Rexall and Well.ca businesses in Canada (“Canadian retail disposal group”) for an adjusted purchase price consisting of a cash payment of $9 million, received at closing, and a note of $120 million, measured at fair value and accruing interest upon satisfaction of certain conditions, and payable to the Company at the end of six years. Within the International segment and as part of the transaction, the Company divested net assets of $741 million, including $125 million of intercompany trade accounts payable primarily related to purchases of inventories from McKesson Canada assumed by the buyer upon divestiture. The Company determined that the disposal group did not meet the criteria for classification as discontinued operations.
During the year ended March 31, 2025, the Company recorded net charges of $667 million within “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations, to remeasure the Canadian retail disposal group to fair value less costs to sell. The remeasurement adjustment for the year ended March 31, 2025 includes a $48 million loss related to the accumulated other comprehensive loss balances associated with the Canadian retail disposal group. The Company’s measurement of the fair value of the Canadian retail disposal group was based on the total consideration expected to be received by the Company as outlined in the transaction agreements. Certain components of the total consideration included Level 3 fair value measurements.
European Divestiture Activities
In July 2021, the Company announced its intention to exit its businesses in Europe (“European Divestiture Activities”), as discussed in more detail below. Net gains related to these divestiture activities during the year ended March 31, 2023 were not material. The gains and charges for fiscal 2023 were recorded within “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations. The Company determined that the disposal groups did not meet the criteria for classification as discontinued operations.
On October 31, 2022, the Company completed its previously announced transaction to sell certain of its businesses in the E.U. located in France, Italy, Ireland, Portugal, Belgium, and Slovenia, along with its German headquarters and wound-care business, part of a shared services center in Lithuania, and its ownership stake in a joint venture in the Netherlands (“E.U. disposal group”) to the PHOENIX Group. As part of the transaction, the Company received cash proceeds of $892 million and divested net assets of $1.3 billion, including cash of $319 million, derecognized the carrying value of its noncontrolling interest held by minority shareholders of McKesson Europe of $382 million, and released $153 million of net accumulated other comprehensive loss. During the year ended March 31, 2023 the Company recorded net gains of $66 million to remeasure the E.U. disposal group to fair value less costs to sell. The Company’s measurement of the fair value of the E.U. disposal group was based on the total consideration received by the Company as outlined in the transaction agreement. Certain components of the total consideration included fair value measurements that fall within Level 3 of the fair value hierarchy.
At March 31, 2025 and 2024, the Company had no assets or liabilities related to European divestiture activities that met the criteria for classification as held for sale. Subsequent to the divestiture activities discussed above, the Company’s European operations primarily consist of its retail and distribution businesses in Norway.
Other
For the periods presented, the Company also completed de minimis acquisitions and divestitures within its operating segments. Financial results for the Company’s business acquisitions have been included in its consolidated financial statements as of their respective acquisition dates. Purchase prices for business acquisitions have been allocated based on estimated fair values at the respective acquisition dates.
On April 2, 2025, the Company announced the completion of its previously announced acquisition of a controlling interest in PRISM Vision Holdings, LLC (“PRISM Vision”), a leading provider of general ophthalmology and retina management services. The Company acquired an approximate 80% interest in PRISM Vision for approximately $850 million. PRISM Vision physicians retained an approximate 20% interest. The financial results of PRISM Vision will be reported within the Company’s U.S. Pharmaceutical segment.

4. Share-Based Compensation
The Company provides share-based compensation to its employees, officers, and non-employee directors, including restricted stock units (“RSUs”), performance-based stock units (“PSUs”), and an employee stock purchase plan (“ESPP”) (collectively, “share-based awards”). Most of the share-based awards are granted in the first quarter of each fiscal year.
Share-based compensation expense for the share-based awards is recognized for the portion of awards ultimately expected to vest. The Company estimates the number of share-based awards that will ultimately vest primarily based on historical experience. The estimated forfeiture rate established upon grant is re-assessed throughout the requisite service period and is adjusted when actual forfeitures occur. The actual forfeitures in future reporting periods could be higher or lower than current estimates.
Share-based compensation expense is classified in the Consolidated Statements of Operations in the same manner as cash compensation paid to the Company’s employees and included in “Selling, distribution, general, and administrative expenses.”

Share-based compensation expense, net of tax | $ | 141 |  |  | $ | 110 |  |  | $ | 75 |

(1)Includes share-based compensation expense recognized for RSUs and PSUs.
Stock Plans
In April 2022, the Company’s stockholders approved the McKesson Corporation 2022 Stock Plan (the “2022 Stock Plan”), which permits the grant of awards in the form of restricted stock, RSUs, PSUs, stock options, and other share-based awards to selected employees, officers, and non-employee directors. As of March 31, 2025, 4.2 million shares remain available for future grant under the 2022 Stock Plan.
Restricted Stock Unit Awards
RSUs entitle the holder to receive a specified number of shares of the Company’s common stock which vest over a period of generally three to four years as determined by the Compensation Committee at the time of grant. The fair value of the award is determined based on the price of the Company’s common stock on the grant date and the related share-based compensation expense is recognized over the vesting period on a straight-line basis.
Non-employee directors receive an annual grant of RSUs, which vest immediately and are expensed upon grant. The director may elect to receive the underlying shares immediately or defer receipt of the shares if they meet director stock ownership guidelines. The shares will be automatically deferred for those directors who do not meet the director stock ownership guidelines. At March 31, 2025, approximately 33,000 RSUs for the Company’s directors were vested.
Performance Stock Unit Awards
PSUs are conditional upon the attainment of market and performance objectives over a specified period. The number of vested PSUs is assessed at the end of a three-year performance period upon attainment of meeting certain earnings per share targets, average return on invested capital, and for certain participants, total shareholder return relative to a peer group of companies. The Company uses the Monte Carlo simulation model to measure the fair value of the total shareholder return portion of the PSUs. The earnings per share portion of the PSUs is measured at the grant date market price. PSUs have a requisite service period of generally three years. Expense is attributed to the requisite service period on a straight-line basis based on the fair value of the PSUs, adjusted for the performance modifier at the end of each reporting period. For PSUs that are designated as equity awards, the fair value is measured at the grant date.

Employee Stock Purchase Plan
The Company has an ESPP under which 23.1 million shares have been authorized for issuance. The ESPP allows eligible employees to purchase shares of the Company’s common stock through payroll deductions. The deductions occur over three-month purchase periods and the shares are then purchased at 85% of the market price at the end of each purchase period. Employees are allowed to terminate their participation in the ESPP at any time during the purchase period prior to the purchase of the shares, subject to the Company’s insider trading policies and procedures. The 15% discount provided to employees on these shares is included in share-based compensation expense. The shares related to funds outstanding at the end of a quarter are included in the calculation of diluted weighted-average shares outstanding. These amounts have not been significant for all the years presented. The Company recognizes costs for employer matching contributions as ESPP expense over the relevant purchase period. Shares issued under the ESPP were not material in fiscal 2025, fiscal 2024, and fiscal 2023. At March 31, 2025, 3.3 million shares remain available for issuance.

(1)The increase in interest income for fiscal 2025 compared to fiscal 2024 is primarily due to higher investable cash in fiscal 2025. The increase in fiscal 2024 compared to fiscal 2023 is primarily due to higher interest rates on certain cash balances.
(2)Represents net realized and unrealized gains and losses as well as impairment charges on the Company’s investments in equity securities of certain U.S. growth stage companies in the healthcare industry. These net gains and losses primarily relate to mark-to-market adjustments for investments which are measured at fair value based on changes in the observable price of the securities and realized gains on the disposal of certain of these investments. Includes net gains of $101 million related to investments in equity securities of certain U.S. growth stage companies in the healthcare industry, partially offset by a loss of $43 million related to an equity method investment for the year ended March 31, 2025. Included a gain of $142 million for the year ended March 31, 2023 related to the exit of one of the Company’s investments in equity securities in July 2022 for proceeds of $179 million.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
During the year ended March 31, 2025, the Company recognized a net discrete tax benefit of $258 million related to the sales of certain intellectual property between McKesson wholly-owned legal entities based in foreign tax jurisdictions. The transferor entities of the intellectual property were not subject to income tax on their transaction. The recipient entities of the intellectual property are entitled to amortize the fair value of the assets for tax purposes. As a result of these transactions, and in accordance with ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, net discrete tax benefits of $44 million and $214 million were recognized in the second and fourth quarters of fiscal 2025, respectively.
During the year ended March 31, 2024, the Company recognized a net discrete tax benefit of $157 million related to the release of a valuation allowance based on management’s reassessment of the amount of its deferred tax assets that are more likely than not to be realized.
During the year ended March 31, 2024, the Company also repatriated certain intellectual property between McKesson wholly-owned legal entities that are based in different tax jurisdictions. The transferor entity of the intellectual property was not subject to income tax on this transaction. The recipient entity of the intellectual property is entitled to amortize the fair value of the assets for tax purposes. As a result of this repatriation and in accordance with ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, a net discrete tax benefit of $147 million was recognized in the first quarter of fiscal 2024. In addition, the Company sold certain intellectual property between McKesson wholly-owned legal entities that are based in different tax jurisdictions, where the transferor entity was subject to income tax and the recipient entity is entitled to amortize the fair value of the assets for tax purposes. As a result of this sale, a net discrete tax expense of $43 million was recognized in the fourth quarter of fiscal 2024.
During the year ended March 31, 2023, the Company recognized discrete tax benefits primarily consisting of $115 million related to statute of limitation expirations and tax settlements in various taxing jurisdictions and $58 million related to the tax impact of share-based compensation.

The following table summarizes the activity related to the Company’s gross unrecognized tax benefits for the last three fiscal years:

| Years Ended March 31,
(In millions) | 2025 |  | 2024 |  | 2023
Unrecognized tax benefits at beginning of period | $ | 1,463 |  |  | $ | 1,399 |  |  | $ | 1,523 |

Unrecognized tax benefits at end of period | $ | 1,532 |  |  | $ | 1,463 |  |  | $ | 1,399 |

As of March 31, 2025, the Company had $1.5 billion in unrecognized tax benefits, of which $1.4 billion would reduce income tax expense and the effective tax rate, if recognized. The increases in unrecognized tax benefits in both fiscal 2025 and fiscal 2024 primarily relate to additions associated with recurring items.
During the next twelve months, the Company does not anticipate any material reduction in its unrecognized tax benefits based on the information currently available. However, this may change as the Company continues to have ongoing discussions with various taxing authorities throughout the year.
During the fourth quarter of fiscal 2023, the Internal Revenue Service (“IRS”) communicated proposed adjustments to taxable income reported in the Company’s fiscal 2018 and fiscal 2019 U.S. Federal Corporate Income Tax returns. The adjustments would increase the Company’s federal income tax liability in the range of $600 million to $700 million. The Company disagrees with the proposed adjustments and intends to pursue resolution through the administrative process with the IRS Independent Office of Appeals and, if necessary, through judicial remedies. During the first quarter of fiscal 2024, the Company filed a formal protest with the IRS. The Company does not anticipate a final resolution of these matters in the next twelve months. Although the final resolution of these matters is uncertain, the Company believes in the merits of its tax positions and believes that it has adequately reserved for any adjustments to the provision of income taxes that may ultimately result. However, if the IRS prevails in these matters, the assessed tax and interest could have a material adverse effect on the Company’s financial position, results of operations, and cash flows in future periods.
The Company reports interest and penalties on income taxes as income tax expense. It recognized income tax expense of $80 million, $84 million, and $31 million in fiscal 2025, fiscal 2024, and fiscal 2023, respectively, representing interest and penalties, in its Consolidated Statements of Operations. As of March 31, 2025 and 2024, the Company accrued cumulatively $302 million and $222 million, respectively, in interest and penalties on unrecognized tax benefits in its Consolidated Balance Sheets.
The Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, and various foreign jurisdictions. The Company is generally subject to audit by taxing authorities in various U.S. states and in foreign jurisdictions for fiscal 2016 through the current fiscal year.
Undistributed earnings of the Company’s foreign operations of approximately $4.0 billion were considered indefinitely reinvested on March 31, 2025. Following the enactment of the 2017 Tax Act, the repatriation of cash to the U.S. is generally no longer taxable for federal income tax purposes. However, the repatriation of cash held outside the U.S. could be subject to applicable foreign withholding taxes and state income taxes. The Company may remit foreign earnings to the U.S. to the extent it is tax efficient to do so. It does not expect the tax impact from remitting these earnings to be material.

7. Noncontrolling Interests
Noncontrolling Interests
Noncontrolling interests represent third-party equity interests in the Company’s consolidated entities primarily related to ClarusONE, Vantage, and SCRI Oncology. After June 15, 2021, noncontrolling interests also represented minority shareholder equity interests in McKesson Europe. The Company’s noncontrolling interest in McKesson Europe was included in the divestiture of the E.U. disposal group in October 2022, as discussed in Financial Note 2, “Business Acquisitions and Divestitures.”
Noncontrolling interests in the Company’s Consolidated Balance Sheets were $380 million and $372 million at March 31, 2025 and 2024, respectively. For the years ended March 31, 2025, 2024, and 2023, the Company allocated a total of $186 million, $158 million, and $162 million of net income to noncontrolling interests, respectively.
Changes in noncontrolling interests for the years ended March 31, 2025, 2024, and 2023 were as follows:

(In millions) |  | Noncontrolling Interests
Balance, March 31, 2022 |  | $ | 480 |

8. Earnings Per Common Share
Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. The computation of diluted earning per common share is similar to that of basic earnings per common share, except that the former reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock. Potentially dilutive securities include outstanding stock options, restricted stock units, and performance-based and other restricted stock units.
Less than one million of potentially dilutive securities for fiscal 2025, fiscal 2024, and fiscal 2023 were excluded from the computation of diluted earnings per common share as they were anti-dilutive.

Goodwill Impairment Charges
The Company evaluates goodwill for impairment on an annual basis in the first fiscal quarter, and more frequently if indicators for potential impairment exist. Goodwill impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or one level below an operating segment (also known as a component), for which discrete financial information is available and segment management regularly reviews the operating results of that reporting unit.
The fair value of the reporting units is determined using a combination of an income approach based on a DCF model and a market approach based on appropriate valuation multiples observed for the reporting unit’s guideline public companies. Fair value estimates result from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions that have been deemed reasonable by management as of the measurement date. Any material changes in key assumptions, including failure to improve operations of certain retail pharmacy stores, additional government reimbursement reductions, deterioration in the financial markets, an increase in interest rates, or an increase in the cost of equity financing by market participants within the industry, or other unanticipated events and circumstances, may affect such estimates. The discount rates are the weighted-average cost of capital measuring the reporting unit’s cost of debt and equity financing weighted by the percentage of debt and percentage of equity in a company’s target capital. The unsystematic risk premium is an input factor used in calculating the discount rate that specifically addresses uncertainty related to the reporting unit’s future cash flow projections. Fair value assessments of the reporting unit are considered a Level 3 measurement due to the significance of unobservable inputs developed using company-specific information.

On June 15, 2023, the Company completed a public offering of 4.90% Notes due July 15, 2028 in a principal amount of $400 million (the “2028 Notes”) and a public offering of 5.10% Notes due July 15, 2033 in a principal amount of $600 million (the “2033 Notes” and, together with the 2028 Notes, the “Notes”). Interest on the Notes is payable semi-annually on January 15th and July 15th of each year, commencing on January 15, 2024. Proceeds received from the issuance of the Notes, net of discounts and offering expenses, were $397 million for the 2028 Notes and $592 million for the 2033 Notes. The Company utilized a portion of the net proceeds from the offerings of the Notes to fund the purchase price payable with respect to the portion of the Company’s then outstanding 3.80% Notes due March 15, 2024 (the “2024 Notes”) that was validly tendered and accepted for purchase pursuant to the Concurrent Tender Offer (as defined below) and to effect the satisfaction and discharge of the remaining portion of the 2024 Notes, all of which is described further below. The remaining net proceeds from the offerings of the Notes was available for general corporate purposes.
On February 15, 2023, the Company completed a public offering of 5.25% Notes due February 15, 2026 (the “February 2026 Notes”) in a principal amount of $500 million. Interest on the February 2026 Notes is payable semi-annually on February 15th and August 15th of each year, commencing on August 15, 2023. Proceeds received from this note issuance, net of discounts and offering expenses, were $497 million. The Company utilized the net proceeds from this note issuance to repay existing debt. On or after February 15, 2024, the Company may redeem the February 2026 Notes at its option, in whole or in part, at any time and from time to time, for cash at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to, but not including, the redemption date.
Each of the 2029 Notes, the 2033 Notes and the 2028 Notes, constitutes a “series,” is an unsecured and unsubordinated obligation of the Company and ranks equally with all of the Company’s existing, and future unsecured and unsubordinated indebtedness that may be outstanding from time-to-time. Each series is governed by an indenture and officers’ certificate that are materially similar to those of other series of notes issued by the Company. Upon at least 10 days’ and not more than 60 days’ notice to holders of the applicable series of the notes, the Company may redeem such series of the notes for cash in whole, at any time, or in part, from time to time, at redemption prices that include accrued and unpaid interest and a make-whole premium before a specified date, and at par plus accrued and unpaid interest thereafter until maturity, each as specified in the indenture and the officers’ certificate. If there were to occur both (a) a change of control of the Company and (b) a downgrade of the applicable series of the notes below an investment grade rating by each of the Ratings Agencies (as defined in the applicable officers’ certificate) within a specified period, then the Company would be required to make an offer to purchase that series at a price equal to 101% of the then outstanding principal amount of that series, plus accrued and unpaid interest to, but not including, the date of repurchase. The indenture and the related officers’ certificate for each series, subject to the exceptions and in compliance with the conditions as applicable, specify that the Company may not consolidate, merge or sell all or substantially all of its assets, incur liens, or enter into sale-leaseback transactions exceeding specific terms, without the lenders’ consent. The indenture also contains customary events of default provisions.
Retirements and Redemption
On March 15, 2023, the Company retired its $360 million outstanding principal amount of 2.85% Notes due 2023 upon maturity. On December 15, 2022, the Company retired its $400 million outstanding principal amount of 2.70% Notes due 2022 upon maturity. All of these notes were repaid or redeemed using cash on hand.
Concurrent Tender Offer of the 2024 Notes
On June 16, 2023, the Company completed a cash tender offer for any and all of its then outstanding 2024 Notes, which was made concurrently with the offerings of the Notes (the “Concurrent Tender Offer”). The Company paid an aggregate consideration of $268 million in the Concurrent Tender Offer to repurchase $271 million principal amount of the 2024 Notes at a repurchase price equal to 98.75% of the principal amount plus accrued and unpaid interest. The repurchase of the 2024 Notes accepted for purchase in the Concurrent Tender Offer was accounted for as a debt extinguishment.

Satisfaction and Discharge of the 2024 Notes
On June 16, 2023, after completing the Concurrent Tender Offer, the Company irrevocably deposited with the trustee under the indenture governing the 2024 Notes (the “2024 Notes Indenture”) U.S. government obligations in an amount sufficient to fund the payment of accrued and unpaid interest of the remaining $647 million principal amount of the 2024 Notes as it became due, and of the principal amount of those 2024 Notes on their March 15, 2024 maturity date. The U.S. government obligations were purchased using a portion of the net proceeds from the offerings of the Notes. After the deposit of such funds with the trustee, the Company’s obligations under the 2024 Notes Indenture with respect to the 2024 Notes were satisfied and discharged and the transaction was accounted for as a debt extinguishment.
The total gain recognized on the debt extinguishments described above for the year ended March 31, 2024 was $9 million and included within “Interest expense” in the Company’s Consolidated Statement of Operations.

Revolving Credit Facilities
5-Year Facility
On November 7, 2022, the Company entered into a Credit Agreement (the “2022 Credit Facility”) which was subsequently amended on November 7,2024 and May 8, 2025, that provides a syndicated $4.0 billion senior unsecured credit facility with a $3.6 billion aggregate sublimit of availability in Canadian dollars, British pound sterling, and Euro. The 2022 Credit Facility was scheduled to mature in November 2027. On November 7, 2024, the maturity date of the 2022 Credit Facility was extended from November 2028 to November 2029. Borrowings under the 2022 Credit Facility bear interest based upon the Term Secured Overnight Financing Rate (“SOFR”) for credit extensions denominated in U.S. dollars, the Sterling Overnight Index Average Reference Rate for credit extensions denominated in British pound sterling, the Euro Interbank Offered Rate for credit extensions denominated in Euros, the Canadian Overnight Repo Rate Average for credit extensions denominated in Canadian dollars, a prime rate, or alternative overnight rates, as applicable, plus agreed upon margins. The 2022 Credit Facility contains various customary investment grade covenants, including a financial covenant which obligates the Company to maintain a maximum Total Debt to Consolidated EBITDA ratio, as defined in the 2022 Credit Facility. If the Company does not comply with these covenants, its ability to use the 2022 Credit Facility may be suspended and repayment of any outstanding balances under the 2022 Credit Facility may be required to be repaid. The remaining terms and conditions of the 2022 Credit Facility are substantially similar to those previously in place under the 2020 Credit Facility. The Company can use funds obtained under the 2022 Credit Facility for general corporate purposes. There were no borrowings under the 2022 Credit Facility during the year ended March 31, 2025 and 2024 and no amounts outstanding at March 31, 2025 or March 31, 2024. At March 31, 2025, the Company was in compliance with all covenants under the 2022 Credit Facility.

364-Day Facility
On May 8, 2025, the Company entered into a Credit Agreement (the “364 Day Credit Facility”), that provides a syndicated $1.0 billion senior unsecured credit facility. The 364 Day Credit Facility is scheduled to mature in May 2026.
On or prior to the maturity date, the Company may, at its election and subject to certain customary conditions, convert the outstanding loans into a term loan that is repayable in May 2027.
Borrowings under the 364 Day Credit Facility bear interest based upon SOFR for credit extensions denominated in U.S. Dollars and other relevant underlying benchmarks, plus agreed margins.
The 364 Day Credit Facility contains various customary investment grade covenants, including a financial covenant which obligates the Company to maintain a maximum Total Debt to Consolidated EBITDA ratio, as defined in the 364 Day Credit Facility. If the Company does not comply with these covenants, its ability to use the 364 Day Credit Facility may be suspended and repayment of any outstanding balances under the 364 Day Credit Facility may be required to be repaid. The terms and conditions of the 364 Day Credit Facility are substantially similar to those under the 2022 Credit Facility. The Company can use funds obtained under the 364 Day Credit Facility for general corporate purposes.
Commercial Paper
The Company maintains a commercial paper program to support its working capital requirements and for other general corporate purposes. Under the program, the Company can issue up to $4.0 billion in outstanding commercial paper notes. During the years ended March 31, 2025, 2024, and 2023, the Company borrowed and repaid $15.1 billion, $20.0 billion, and $8.5 billion, respectively, under the program. At March 31, 2025 and 2024, there were no commercial paper notes outstanding. Following the execution of the 364 Day Facility on May 8, 2025, the Company can issue up to $5.0 billion in outstanding commercial paper notes.
12. Variable Interest Entities
The Company evaluates its ownership, contractual, and other interests in entities to determine if they are VIEs if it has a variable interest in those entities, and the nature and extent of those interests. These evaluations are highly complex and involve management judgment and the use of estimates and assumptions based on available historical information, among other factors. Based on its evaluations, if the Company determines it is the primary beneficiary of such VIEs, it consolidates such entities into its financial statements.
Consolidated Variable Interest Entities
The Company consolidates a VIE when it has the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits of the VIE and, as a result, is considered the primary beneficiary of the VIE. The Company consolidates certain single-lessee leasing entities where it, as the lessee, has the majority risk of the leased assets due to its minimum lease payment obligations to these leasing entities. As a result of absorbing this risk, the leases provide the Company with the power to direct the operations of the leased properties and the obligation to absorb losses or the right to receive benefits of the entity. Consolidated VIEs do not have a material impact on the Company’s Consolidated Statements of Operations or Consolidated Statements of Cash Flows. Total assets and liabilities included in its Consolidated Balance Sheets for these VIEs were $610 million and $47 million, respectively, at March 31, 2025, and $601 million and $41 million, respectively, at March 31, 2024.

Investments in Unconsolidated Variable Interest Entities
The Company is involved with VIEs which it does not consolidate because it does not have the power to direct the activities that most significantly impact their economic performance and thus is not considered the primary beneficiary of the entities. Its relationships include equity method investments and lending, leasing, contractual, or other relationships with the VIEs. The Company’s most significant VIE relationships are with oncology and other specialty practices. Under these practice arrangements, the Company generally owns or leases all of the real estate and equipment used by the practices and manages the practices’ administrative functions. The Company’s maximum exposure to loss (regardless of probability) as a result of all unconsolidated VIEs was $1.6 billion and $1.5 billion at March 31, 2025 and 2024, respectively, which primarily represents the value of intangible assets related to service agreements, lease and loan receivables, operating ROU assets, and equity investments. This amount excludes the customer loan guarantees discussed in Financial Note 16, “Financial Guarantees and Warranties.” The Company believes there is no material loss exposure on these assets or from these relationships.
13. Pension Benefits
The Company maintains a number of qualified and nonqualified defined benefit pension plans and defined contribution plans for eligible employees.
Non-U.S. Defined Benefit Pension Plans
As of March 31, 2025 and 2024, the Company’s non-U.S. defined benefit pension plans cover eligible employees located predominantly in Norway and Canada. Benefits for these plans are based primarily on each employee’s final salary, with annual adjustments for inflation.
The Company divested certain pension assets and liabilities as part of the Canadian divestiture activities in fiscal 2025 and European divestiture activities in fiscal 2023 which are discussed in more detail in Financial Note 2, “Business Acquisitions and Divestitures.” During fiscal 2025, changes in the Company pension assets and accumulated other comprehensive loss related to the Canadian divestiture activities were not material. During fiscal 2023, the Company’s divested pension liabilities totaling $75 million, pension assets of $49 million and the Company released $17 million of losses from accumulated other comprehensive loss related to divestiture activities.
During the fourth quarter of fiscal 2025, the Company settled the frozen U.K. pension plan (“U.K. Plan”) by irrevocably transferring future financial responsibilities for the plan to a third-party insurance provider (the “buy-out”). In connection with the buy-out and settlement of the U.K. Plan, a non-cash pre-tax settlement charge of $87 million was recorded in “Other income, net” in the Company’s Consolidated Statements of Operations for the year ended March 31, 2025, consisting of $53 million of pension losses and $34 million of Foreign currency translation adjustments associated with the plan. Excess assets from the U.K. Plan of approximately $7 million are to be reverted to the Company following final wind-up activities and were recognized as a receivable upon settlement.
Defined benefit plan assets and obligations are measured as of the Company’s fiscal year-end. The net periodic expense for the Company’s pension plans were as follows:

| Years Ended March 31,
(In millions) | 2025 |  | 2024 |  | 2023
Service cost - benefits earned during the year | $ | 2 |  |  | $ | 2 |  |  | $ | 5 |
Interest cost on projected benefit obligation | 7 |  |  | 8 |  |  | 7 |
Expected return on assets | (7) |  |  | (7) |  |  | (5) |
Amortization of unrecognized actuarial loss and prior service costs | 2 |  |  | 2 |  |  | 1 |
Curtailment/settlement loss (gain) | 56 |  |  | — |  |  | (1) |
Net periodic pension expense | $ | 60 |  |  | $ | 5 |  |  | $ | 7 |

The projected unit credit method is utilized in measuring net periodic pension expense over the employees’ service life for the pension plans. Unrecognized actuarial losses exceeding 10% of the greater of the projected benefit obligation or the market value of assets are amortized straight-line over the average remaining future service period of active employees.

In fiscal 2025, the Company recognized $53 million in actuarial losses for the pension plans to stockholders’ deficit as a result of the U.K. plan buy-out. In fiscal 2023, the Company recognized $17 million in net actuarial losses for pension plans to stockholders’ deficit as a result of the divestitures. Refer to Financial Note 2, “Business Acquisitions and Divestitures,” for more information on the Company’s divestiture activities.
Projected benefit obligations related to the Company’s unfunded plans were $19 million at March 31, 2025 and 2024. Funding obligations for its plans vary based on the laws of each jurisdiction.
Expected benefit payments are based on the same assumptions used to measure the benefit obligations and include estimated future employee service. Expected benefit payments for the Company’s pension plans were as follows:

Fiscal 2030 | $ | 17 |
Fiscal 2031 through 2035 | $ | 22 |

Expected contributions to be made for the Company’s pension plans are $3 million for fiscal 2026.
Weighted-average assumptions used to estimate the net periodic pension expense and the actuarial present value of benefit obligations were as follows:

| Years Ended March 31,
| 2025 |  | 2024 |  | 2023
Net periodic pension expense |  |  |  |  |
Discount rates | 4.55 | % |  | 4.54 | % |  | 2.67 | %
Rate of increase in compensation | 3.21 |  |  | 3.21 |  |  | 3.67 |

Benefit obligation |  |  |  |  |
Discount rates | 4.48 | % |  | 4.55 | % |  | 4.54 | %
Rate of increase in compensation | 3.47 |  |  | 3.21 |  |  | 3.21 |

The Company’s defined benefit pension plan liabilities are valued using a discount rate based on a yield curve developed from a portfolio of high-quality corporate bonds rated AA or better whose maturities are aligned with the expected benefit payments of its plans. The Company’s defined benefit pension plan liabilities are valued using a weighted-average discount rate of 4.48%, which represents a decrease of seven basis points from its fiscal 2024 weighted-average discount rate of 4.55%.
Plan Assets
Investment Strategy: For plan assets, the investment strategies are subject to local regulations and the asset/liability profiles of the plans in each individual country. Plan assets are broadly invested in a manner appropriate to the nature and duration of the expected future retirement benefits payable under the plans. Plan assets are primarily invested in high-quality corporate and government bond funds and equity securities. Assets are properly diversified to avoid excessive reliance on any particular asset, issuer, or group of undertakings so as to avoid accumulations of risk in the portfolio as a whole.
The Company develops the expected long-term rate of return assumption based on the projected performance of the asset classes in which plan assets are invested. The target asset allocation was determined based on the liability and risk tolerance characteristics of the plans and at times may be adjusted to achieve overall investment objectives.

Fair Value Measurements: The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on unadjusted quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs. The following tables represent the Company’s plan assets as of March 31, 2025 and 2024, using the fair value hierarchy by asset class:

(1) Equity commingled funds, fixed income commingled funds, real estate funds, and other investments for which fair value is measured using the NAV per share as a practical expedient are not leveled within the fair value hierarchy and are included as a reconciling item to total investments.
Cash and cash equivalents - Cash and cash equivalents include money market funds and other commingled funds, which have daily net asset values derived from the underlying securities.
Equity commingled funds - Some equity investments are held in commingled funds, which have daily net asset values derived from quoted prices for the underlying securities in active markets.
Fixed income securities - Fixed income securities consist of bonds and debentures. Inputs to the valuation methodology include quoted prices for similar assets in active markets, and inputs that are observable for the asset, either directly or indirectly, for substantially the full term of the asset.
Annuity contracts - The value of the annuity contracts is reported by the Trustee and is based on a valuation of the remaining contracted cash flow of the contract. Inputs in the valuation include discounted future cash flows.
Real estate funds - The value of the real estate funds is reported by the fund manager and is based on a valuation of the underlying properties. Inputs used in the valuation include items such as cost, discounted future cash flows, independent appraisals, and market based comparable data.
Other - At March 31, 2025 and 2024, this includes $34 million and $30 million, respectively, of plan asset value relating to obligations in Norway for the state-regulated pension plan which is managed by the Norwegian Public Service Pension Fund (“SPK”). According to the terms of the SPK, the plan assets of state regulated plans in Norway must correspond very closely to the pension obligation calculated using the principles codified in Norwegian law. The investment return credited to this account is determined annually based on the performance of long-term government bonds.

Defined Contribution Plans
The Company has a contributory retirement savings plan (“RSP”) for U.S. eligible employees. Eligible employees may contribute to the RSP up to 75% of their eligible compensation on a pre-tax or post-tax basis not to exceed IRS limits. The Company makes matching contributions in an amount equal to 100% of the employee’s first 3% of pay contributed and 50% for the next 2% of pay contributed. The Company, at the discretion of its Board of Directors (the “Board”), may also make an additional annual matching contribution for each plan year to enable participants to receive a full match based on their annual contribution. The Company also contributed to non-U.S. plans that are available in certain countries. Contribution expenses for the RSP and non-U.S. plans were $128 million, $138 million, and $125 million for the years ended March 31, 2025, 2024, and 2023, respectively.
Postretirement Benefits
The Company maintains a number of postretirement benefit plans, primarily consisting of healthcare and life insurance (“welfare”) benefits, for certain eligible U.S. employees. Eligible employees consist of those who retired before March 31, 1999 and those who retired after March 31, 1999, but were an active employee as of that date, after meeting other age-related criteria. It also provides postretirement benefits for certain U.S. executives. Defined benefit plan obligations are measured as of the Company’s fiscal year-end. The net periodic credit or expense for the Company’s postretirement welfare benefits was not material for the years ended March 31, 2025, 2024, and 2023. The benefit obligation at March 31, 2025 and 2024 was $40 million and $42 million, respectively.
14. Hedging Activities
In the normal course of business, the Company is exposed to interest rate and foreign currency exchange rate fluctuations. At times, the Company limits these risks through the use of derivatives as described below. In accordance with the Company’s policy, derivatives are only used for hedging purposes. The Company does not use derivatives for trading or speculative purposes. The Company uses various counterparties for its derivative contracts to minimize the exposure to credit risk but does not anticipate non-performance by these parties.
Foreign Currency Exchange Risk
The Company conducts its business worldwide in U.S. dollars and the functional currencies of its foreign subsidiaries, including Canadian dollars, Euro, and British pounds sterling. Changes in foreign currency exchange rates could have a material adverse impact on the Company’s financial results that are reported in U.S. dollars. The Company is also exposed to foreign currency exchange rate risk related to its foreign subsidiaries, including intercompany loans denominated in non-functional currencies. The Company has certain foreign currency exchange rate risk programs that use foreign currency forward contracts and cross-currency swaps. These forward contracts and cross-currency swaps are generally used to offset the potential income statement effects from intercompany loans and other obligations denominated in non-functional currencies. These programs reduce but do not entirely eliminate foreign currency exchange rate risk.
Interest Rate Risk
The Company has exposure to changes in interest rates, and it utilizes risk programs which use interest rate swaps to hedge the changes in debt fair values caused by fluctuations in benchmark interest rates. The Company also enters into forward contracts to hedge the variability of future benchmark interest rates on any planned bond issuances. These programs reduce but do not entirely eliminate interest rate risk.

FINANCIAL NOTES (Continued)
Non-Derivative Instruments Designated as Hedges
Prior to the divestiture of the E.U. disposal group, the Company’s €1.1 billion of Euro-denominated notes were designated as non-derivative net investment hedges. These hedges were utilized to hedge portions of the Company’s net investments in non-U.S. subsidiaries against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. For all notes that were designated as net investment hedges and met effectiveness requirements, the changes in carrying value of the notes attributable to the change in spot rates were recorded as foreign currency translation adjustments in “Accumulated other comprehensive loss” in the Consolidated Statements of Stockholders’ Equity (Deficit) where they offset foreign currency translation gains and losses recorded on the Company’s net investments. To the extent foreign currency-denominated notes designated as net investment hedges were ineffective, changes in carrying value attributable to the change in spot rates were recorded in earnings.
In connection with the sale of the E.U. disposal group in October 2022, the Company reclassified $112 million of gains from accumulated other comprehensive loss to “Selling, distribution, general, and administrative expenses” in the Consolidated Statement of Operations for the year ended March 31, 2023. This amount related to the €1.1 billion of Euro-denominated notes described above which were de-designated as net investment hedges, along with certain other Euro-denominated notes which were previously accounted for as net investment hedges and matured in prior periods, and was included in the fiscal 2023 and fiscal 2022 calculations of charges to remeasure the assets and liabilities of the disposal group to fair value less costs to sell.
In connection with the sale of the U.K. disposal group in April 2022, the Company reclassified $26 million of gains from accumulated other comprehensive loss to “Selling, distribution, general, and administrative expenses” in the Consolidated Statement of Operations for the year ended March 31, 2023. This amount related to the Company’s £450 million of British pound sterling-denominated notes, which were previously accounted for as net investment hedges until de-designated in fiscal 2020, and was included in the fiscal 2022 calculation of charges to remeasure the assets and liabilities of the disposal group to fair value less costs to sell.

Net Investment Hedges
The Company uses cross-currency swaps to hedge portions of the Company’s net investments denominated in Canadian dollars against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. The changes in the fair value of these derivatives attributable to the changes in spot currency exchange rates and differences between spot and forward interest rates are recorded in accumulated other comprehensive loss and offset foreign currency translation gains and losses recorded on the Company’s net investments denominated in Canadian dollars. To the extent cross-currency swaps designated as hedges are ineffective, changes in carrying value attributable to the change in spot rates are recorded in earnings.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
In fiscal 2025, the Company expanded the net investment hedging program by entering into new cross-currency swaps and restructuring existing cross-currency swaps as described below. As of March 31, 2025, the outstanding notional amount of cross-currency swaps was C$6.5 billion.
In the first quarter of fiscal 2025, the Company entered into cross-currency swaps designated as net investment hedges with a total notional amount of C$2.5 billion to hedge portions of the Company’s net investments denominated in Canadian dollars against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. These cross-currency swaps mature in April 2025 and June 2026. Further, the Company terminated C$1.5 billion of cross-currency swaps designated as net investment hedges with original maturity dates in November 2024 and extending through March 2025.
In the third quarter of fiscal 2025, the Company entered into cross-currency swaps designated as net investment hedges with a total notional amount of C$6.0 billion. These cross-currency swaps mature in October, November and December 2026. Further, the Company terminated C$5.0 billion of cross-currency swaps designated as net investment hedges with original maturity dates in April 2025, June, October and November 2026.
In the fourth quarter of fiscal 2025, the Company entered into cross-currency swaps designated as net investment hedges with a total notional amount of C$3.0 billion. These cross-currency swaps mature in March 2027.
Fair Value Hedges
The Company uses cross-currency swaps to hedge the changes in the fair value of its foreign currency notes resulting from changes in benchmark interest rates and foreign currency exchange rates. In February 2023, £450 million of cross-currency swaps matured and the Company executed new cross-currency swaps with similar terms to continue to mitigate interest rate and foreign exchange rate risks.
In fiscal 2023, the Company entered into cross-currency fixed-to-fixed interest rate swaps with a total notional amount of €1.1 billion to hedge the changes in the fair value of its underlying Euro-denominated notes resulting from changes in benchmark interest rates and foreign currency exchange rates.
In fiscal 2023, the Company entered into floating interest rate swaps designated as fair value hedges to convert $1.3 billion of its fixed rate debt to floating rate in order to hedge the changes in fair value caused by fluctuations in the benchmark interest rate. In fiscal 2025, $500 million of the $1.3 billion floating interest rate swaps with original maturity dates in February 2026 and callable at any time after February 2024 were terminated. Refer to Financial Note 11, “Debt and Financing Activities,” for additional information on the public offering of the 2029 Notes. The changes in the fair value of these derivatives are recorded in “Interest expense” in the Consolidated Statements of Operations.
The changes in the fair value of these derivatives and the offsetting changes in the fair value of the hedged notes are recorded in earnings. Gains from the changes in the Company’s fair value hedges recorded in earnings were largely offset by the losses recorded in earnings on the hedged item. For components excluded from the assessment of hedge effectiveness, the initial value of the excluded component is recognized in accumulated other comprehensive income (loss) and then released into earnings over the life of the hedging instrument. The difference between the change in the fair value of the excluded component and the amount amortized into earnings during the period is recorded in other comprehensive income (loss).

Cash Flow Hedges
From time to time, the Company enters into cross-currency swaps to hedge intercompany loans denominated in nonfunctional currencies to reduce the income statement effects arising from fluctuations in foreign currency exchange rates. The Company also enters into forward contracts to hedge the variability of future benchmark interest rates on any planned bond issuances and to offset the potential income statement effects from obligations denominated in non-functional currencies. The effective portion of changes in the fair value of these hedges is recorded in accumulated other comprehensive loss and reclassified into earnings in the same period in which the hedged transaction affects earnings. Changes in fair values representing hedge ineffectiveness are recognized in current earnings There were no gains or losses reclassified from accumulated other comprehensive loss and recorded in “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations for the years ended March 31, 2025, 2024, and 2023.
In the fourth quarter of fiscal 2025, the Company executed a series of forward-starting interest rate swap locks with notional amounts of $850 million to hedge cash flows associated with interest payments on upcoming financing activities. Refer to Financial Note 11, “Debt and Financing Activities,” for information on the Company’s debt obligations.
In April 2025, the Company executed forward-starting interest rate swap locks with a total notional amount of $550 million. These swaps, in combination with the swaps executed during the fourth quarter of fiscal 2025, will hedge cash flows associated with interest payments on upcoming financing activities.
In the third quarter of fiscal 2024, the Company entered into foreign currency forward contracts designated as cash flow hedges with a total notional amount of £45 million to hedge the variability of foreign currency exchange fluctuations in future cash payments due to a third party for capital expenditures, and certain of these contracts matured in the fourth quarter of fiscal 2024 and during fiscal 2025.
In fiscal 2023, the Company entered into forward-starting fixed interest rate swaps designated as cash flow hedges, with a combined notional amount of $450 million, and in the first quarter of fiscal 2024 with a notional amount of $50 million, to hedge the variability of future benchmark interest rates on a planned bond issuance. On June 15, 2023, the Company completed a public offering of the 2033 Notes, at which point the $500 million cash flow hedges were terminated and the proceeds are being amortized to interest expense over the life of the 2033 Notes, or 10 years. Refer to Financial Note 11, “Debt and Financing Activities,” for additional information on the public offering of the 2033 Notes.
In fiscal 2023, the Company also terminated its $500 million notional forward-starting fixed interest rate swaps and recognized a gain of $97 million within “Other income, net” in the Consolidated Statement of Operations.
Derivatives Not Designated as Hedges
Derivative instruments not designated as hedges are marked-to-market at the end of each accounting period with the change in fair value included in earnings. Changes in the fair values for contracts not designated as hedges were recorded directly into earnings in “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations. Changes in the fair values were not material for the year ended March 31, 2023. The Company did not enter into any derivative instruments not designated as hedges during fiscal 2025 and fiscal 2024.

Refer to Financial Note 15, “Fair Value Measurements,” for more information on these recurring fair value measurements.
15. Fair Value Measurements
The Company measures certain assets and liabilities at fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures. The fair value hierarchy consists of three levels of inputs that may be used to measure fair value as follows:
Level 1 - quoted prices in active markets for identical assets or liabilities.
Level 2 - significant other observable market-based inputs.
Level 3 - significant unobservable inputs for which little or no market data exists and requires considerable assumptions that are significant to the fair value measurement.

Assets and Liabilities Measured at Fair Value on a Recurring Basis
Cash and cash equivalents at March 31, 2025 and 2024 included investments in money market funds of $1.0 billion and $705 million, respectively, which are reported at fair value. The fair value of money market funds was determined using quoted prices for identical investments in active markets, which are considered to be Level 1 inputs under the fair value measurements and disclosure guidance. The carrying value of all other cash equivalents approximates their fair value due to their relatively short-term nature.
Fair values of the Company’s interest rate swaps, cross-currency swaps, and foreign currency forward contracts were determined using observable inputs from available market information, including quoted interest rates, foreign currency exchange rates, and other observable inputs from available market information. These inputs are considered Level 2 under the fair value measurements and disclosure guidance, and may not be representative of actual values that could have been realized or that will be realized in the future. Refer to Financial Note 14, “Hedging Activities,” for fair values and other information on the Company’s derivatives.
The Company holds investments in equity and debt securities of U.S. growth stage companies that address both current and emerging business challenges in the healthcare industry and which had a carrying value of $103 million and $240 million at March 31, 2025 and 2024, respectively. These investments primarily consist of equity securities without readily determinable fair values and are included in “Other non-current assets” in the Consolidated Balance Sheets. During fiscal 2025, the Company recognized impairment charges and realized gains on the exit of certain investments. During fiscal 2024, the Company recognized impairment charges and unrealized gains on certain investments. During fiscal 2023, the Company recognized impairment charges and realized gains on the exit of certain investments. The Company recognized a net gain of $101 million in fiscal 2025, a net loss of $24 million in fiscal 2024 and a net loss of $36 million in fiscal 2023. These amounts were recorded in “Other income, net” in the Consolidated Statements of Operations. Of the gain recognized in fiscal 2025, $100 million relates to a recapitalization event of one of the Company’s investments in equity securities which resulted in an increase to the carrying value of this investment. Proceeds from the sale of a portion of this investment were $92 million. Additionally, during the fourth quarter of fiscal 2025, the Company exited one of its publicly-traded investments, receiving cash of $97 million and recognizing a gain of $44 million for the year ended March 31, 2025 offset by $44 million asset impairments recorded in the fourth quarter of fiscal 2025. The carrying value of publicly traded investments was determined using quoted prices for identical investments in active markets and are considered to be Level 1 inputs.
Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
In addition to assets and liabilities that are measured at fair value on a recurring basis, the Company’s assets and liabilities are also subject to nonrecurring fair value measurements. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges, including long-lived assets associated with the Company’s restructuring initiatives as discussed in more detail in Financial Note 3, “Restructuring, Impairment, and Related Charges, Net,” or as a result of charges to remeasure assets classified as held for sale to fair value less costs to sell.
At March 31, 2024, the contingent consideration liability related to the Company’s acquisition of RxSS in November 2022 was measured at fair value on a nonrecurring basis. Refer to Financial Note 2, “Business Acquisitions and Divestitures" for more information on these transactions.
The aforementioned investments in equity securities of U.S. growth stage companies include the carrying value of investments without readily determinable fair values, which were determined using a measurement alternative and are recorded at cost less impairment, plus or minus any changes in observable price from orderly transactions of the same or similar security of the same issuer. These inputs related to changes in observable price are considered Level 2 under the fair value measurements and disclosure guidance and may not be representative of actual values that could have been realized or that will be realized in the future. Inputs related to impairments of investments are generally considered Level 3 fair value measurements due to their inherently unobservable nature based on significant assumptions by management and use of company-specific information.
There were no other material assets or liabilities measured at fair value on a nonrecurring basis at March 31, 2025 and 2024.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
Other Fair Value Disclosures
At March 31, 2025 and 2024, the carrying amounts of cash, certain cash equivalents, restricted cash, receivables, drafts and accounts payable, and other current liabilities approximated their estimated fair values because of the short-term maturity of these financial instruments.
The Company determines the fair value of commercial paper using quoted prices in active markets for identical instruments, which are considered Level 1 inputs under the fair value measurements and disclosure guidance.
The Company’s long-term debt is recorded at amortized cost. The carrying value and fair value of the Company’s long-term debt was as follows:

| March 31, 2025 |  | March 31, 2024 |  |
(In millions) | Carrying Value |  | Fair Value |  | Carrying Value |  | Fair Value |  |
Long-term debt, including current maturities | $ | 5,654 |  |  | $ | 5,598 |  |  | $ | 5,629 |  |  | $ | 5,488 |  |  |

The estimated fair value of the Company’s long-term debt was determined using quoted market prices in a less active market and other observable inputs from available market information, which are considered to be Level 2 inputs, and may not be representative of actual values that could have been realized or that will be realized in the future.
Goodwill
Fair value assessments of the reporting unit and the reporting unit's net assets, which are performed for goodwill impairment tests, are considered a Level 3 measurement due to the significance of unobservable inputs developed using company-specific information. The Company considered a market approach as well as an income approach using a DCF model to determine the fair value of each reporting unit.
Long-lived Assets
The Company utilizes multiple approaches including the DCF model and market approaches for estimating the fair value of intangible assets. The future cash flows used in the analysis are based on internal cash flow projections from its long-range plans and include significant assumptions by management. Accordingly, the fair value assessment of long-lived assets is considered a Level 3 fair value measurement.
The Company measures certain long-lived and intangible assets at fair value on a nonrecurring basis when events occur that indicate an asset group may not be recoverable. If the carrying amount of an asset group is not recoverable, an impairment charge is recorded to reduce the carrying amount by the excess over its fair value. Refer to Financial Note 3, “Restructuring, Impairment, and Related Charges, Net” under the heading “Long-Lived Asset Impairments” for more information.
16. Financial Guarantees and Warranties
Financial Guarantees
The Company has agreements with certain of its customers’ financial institutions, primarily in its International segment, under which it has guaranteed the repurchase of its customers’ inventory or its customers’ debt in the event these customers are unable to meet their obligations to those financial institutions. For the Company’s inventory repurchase agreements, among other requirements, inventories must be in a resalable condition and any repurchase would be at a discount. The inventory repurchase agreements mostly relate to certain Canadian customers and generally range from one to two years. Customers’ debt guarantees generally range from three to five years and are primarily provided to facilitate financing for certain customers. The majority of the Company’s customers’ debt guarantees are secured by certain assets of the customer. At March 31, 2025, the maximum amounts of inventory repurchase guarantees and customers’ debt guarantees were $390 million and $5 million, respectively, of which the Company has not accrued any amounts.

The expirations of these financial guarantees were as follows:

(In millions) | Financial Guarantees Subject to Expiration
Fiscal 2026 | $ | 111 |
Fiscal 2027 | 233 |
Fiscal 2028 | 7 |
Fiscal 2029 | 3 |
Fiscal 2030 | 6 |
Thereafter | 35 |

At March 31, 2025, the Company’s banks and insurance companies have issued $206 million of standby letters of credit and surety bonds, which were issued on the Company’s behalf primarily related to its customer contracts and in order to meet the security requirements for statutory licenses and permits, court and fiduciary obligations, pension obligations in Europe, and its workers’ compensation and automotive liability programs.
The Company’s software license agreements generally include certain provisions for indemnifying customers against liabilities if its software products infringe a third party’s intellectual property rights. To date, the Company has not incurred any material costs as a result of such indemnification agreements and has not accrued any liabilities related to such obligations.
In conjunction with certain transactions, primarily divestitures, the Company may provide routine indemnification agreements (such as retention of previously existing environmental, tax, and employee liabilities) whose terms vary in duration and often are not explicitly defined. Where appropriate, obligations for such indemnifications are recorded as liabilities. Because the amounts of these indemnification obligations often are not explicitly stated, the overall maximum amount of these commitments cannot be reasonably estimated. Other than obligations recorded as liabilities at the time of divestiture, the Company has historically not made material payments as a result of these indemnification provisions.
Warranties
In the normal course of business, the Company provides certain warranties and indemnification protection for its products and services. For example, the Company provides warranties that the pharmaceutical and medical-surgical products it distributes are in compliance with the U.S. Food, Drug, and Cosmetic Act and other applicable laws and regulations. It has received the same warranties from its suppliers, which customarily are the manufacturers of the products. In addition, the Company has indemnity obligations to its customers for these products, which have also been provided from its suppliers, either through express agreement or by operation of law. Accrued warranty costs were not material to the Consolidated Balance Sheets as of March 31, 2025 and 2024.
17. Commitments and Contingent Liabilities
In addition to commitments and obligations incurred in the ordinary course of business, the Company is subject to a variety of claims and legal proceedings, including claims from customers and vendors, pending and potential legal actions for damages, governmental investigations, and other matters. The Company is vigorously defending itself against those claims and in those proceedings. Significant developments in those matters are described below. If the Company is unsuccessful in defending, or if it determines to settle, any of these matters, it may be required to pay substantial sums, be subject to injunction and/or be forced to change how it operates its business, which could have a material adverse impact on its financial position or results of operations.

FINANCIAL NOTES (Continued)
Unless otherwise stated, the Company is unable to reasonably estimate the loss or a range of possible loss for the matters described below. Often, the Company is unable to determine that a loss is probable, or to reasonably estimate the amount of loss or a range of loss, for a claim because of the limited information available and the potential effects of future events and decisions by third parties, such as courts and regulators, that will determine the ultimate resolution of the claim. Many of the matters described are at preliminary stages, raise novel theories of liability, or seek an indeterminate amount of damages. It is not uncommon for claims to remain unresolved over many years. The Company reviews loss contingencies at least quarterly to determine whether the likelihood of loss has changed and whether it can make a reasonable estimate of the loss or range of loss. When the Company determines that a loss from a claim is probable and reasonably estimable, it records a liability for an estimated amount. The Company also provides disclosure when it is reasonably possible that a loss may be incurred or when it is reasonably possible that the amount of a loss will exceed its recorded liability. Amounts included within “Claims and litigation charges, net” in the Consolidated Statements of Operations consist of estimated loss contingencies related to opioid-related litigation matters, as well as any applicable income items or credit adjustments due to subsequent changes in estimates.
Litigation and Claims Involving Distribution of Controlled Substances
The Company and its affiliates have been sued as defendants in many cases asserting claims related to distribution of controlled substances, such as opioids. They have been named as defendants along with other pharmaceutical wholesale distributors, pharmaceutical manufacturers, and retail pharmacies. The plaintiffs in these actions have included state attorneys general, county and municipal governments, school districts, tribal nations, hospitals, health and welfare funds, third-party payors, and individuals. These actions have been filed in state and federal courts throughout the U.S., and in Puerto Rico and Canada. These plaintiffs have sought monetary damages and other forms of relief based on a variety of causes of action, including negligence, public nuisance, unjust enrichment, and civil conspiracy, as well as alleging violations of the Racketeer Influenced and Corrupt Organizations Act (“RICO”), state and federal controlled substances laws, and other statutes. Because of the many uncertainties associated with opioid-related litigation matters, the Company is not able to conclude that a liability is probable or provide a reasonable estimate for the range of ultimate possible loss for opioid-related litigation matters other than those for which an accrual is described below.
State and Local Government Claims
The Company and two other national pharmaceutical distributors (collectively “Distributors”) entered into a governmental entities opioid settlement agreement (the “Settlement”) and consent judgment with 48 states and their participating subdivisions, as well as the District of Columbia and all eligible territories (the “Settling Governmental Entities”). Approximately 2,300 cases have been dismissed. The Distributors did not admit liability or wrongdoing and do not waive any defenses pursuant to the Settlement. Under the Settlement, the Company has paid the Settling Governmental Entities approximately $2.0 billion as of March 31, 2025, and additionally will pay the Settling Governmental Entities up to approximately $5.9 billion through 2038. A minimum of 85% of the Settlement payments must be used by state and local governmental entities to remediate the opioid epidemic, while the remainder relates to plaintiffs’ attorneys’ fees and costs and will be paid out through 2030. Pursuant to the Settlement, the Distributors are in the process of establishing a clearinghouse to consolidate their controlled-substance distribution data, which will be available to the settling U.S. states to use as part of their anti-diversion efforts.
Alabama and West Virginia did not participate in the Settlement. Under a separate settlement agreement with Alabama and its subdivisions, the Company has paid approximately $75 million as of March 31, 2025, and additionally will pay approximately $99 million through 2031. The Company previously settled with the state of West Virginia in 2018, so West Virginia and its subdivisions were not eligible to participate in the Settlement. Under a separate settlement agreement, the Company has paid certain West Virginia subdivisions approximately $68 million as of March 31, 2025, and additionally will pay approximately $84 million through 2033. That agreement does not include school districts or the claims of Cabell County and the City of Huntington. After a trial, the claims of Cabell County and the City of Huntington, were decided in the Company’s favor on July 4, 2022. Those subdivisions appealed that decision.
Some other state and local governmental subdivisions did not participate in the Settlement, including certain municipal governments, government hospitals, school districts, and government-affiliated third-party payors. The Company contends that those subdivisions’ claims are foreclosed by the Settlement or other dispositive defenses, but the subdivisions contend that their claims are not foreclosed.

The City of Baltimore, Maryland, is one such subdivision. A trial of its claims against the Company and another national pharmaceutical distributor began on September 16, 2024 in the Circuit Court of Maryland for Baltimore City, Mayor and City Council of Baltimore v. Purdue Pharma LP, No. 24-C-18-000515. Baltimore claims that the defendants’ distribution of controlled substances to certain pharmacies in the City of Baltimore and Baltimore County caused a public nuisance. On November 12, 2024, the jury returned a verdict finding the Company liable and assessing approximately $192 million in compensatory damages. A second phase of the trial, in which the city seeks monetary abatement relief, began on December 11, 2024, and the court is currently considering whether to award additional relief. The judgment is not final, and the Company has filed a motion seeking to set aside the verdict. The Company believes it has valid bases to challenge the verdict and is prepared to appeal, if necessary. Because of the many bases to challenge the verdict, both in the trial court and on appeal, the Company has not adjusted its litigation reserve as a result of the jury verdict.
The district attorneys of the City of Philadelphia, Pennsylvania, and Allegheny County, Pennsylvania did not participate in the Settlement and sought to bring separate claims against the Company, notwithstanding the settlement with the state of Pennsylvania and its attorney general. On January 26, 2024, the Commonwealth Court of Pennsylvania ruled that the Pennsylvania attorney general had settled and fully released the claims brought by those district attorneys under Pennsylvania’s Unfair Trade Practices and Consumer Protection Law. The district attorneys have appealed that decision to the Supreme Court of Pennsylvania. An accrual for the remaining governmental subdivision claims is reflected in the total estimated liability for opioid-related claims in a manner consistent with how Settlement amounts were allocated to Settling Governmental Entities.
Native American Tribe Claims
The Company also entered into settlement agreements for opioid-related claims of federally recognized Native American tribes. Under those agreements, the Company has paid the settling Native American tribes approximately $112 million as of March 31, 2025, and additionally will pay approximately $84 million through 2027. A minimum of 85% of the total settlement payments must be used by the settling Native American tribes to remediate the opioid epidemic.
Non-Governmental Plaintiff Claims
The Company is also a defendant in hundreds of opioid-related cases brought in the U.S. by private plaintiffs, such as hospitals, health and welfare funds, third-party payors, and individuals. These claims, and those of private entities generally, are not included in the settlement agreements described above. The Company and two other national distributors have reached settlements with representatives of nationwide groups of acute care hospitals and certain third-party payors. The claims of remaining U.S. non-governmental plaintiffs are not included in the charges recorded by the Company (described below).
With respect to the acute care hospitals for the year ended March 31, 2024, the Company recorded a charge of $149 million within “Claims and litigation charges, net” in the Consolidated Statement of Operations to reflect its portion of a settlement with a nationwide class of acute care hospitals, of which $75 million was recorded within Corporate expenses, net, and $74 million was recorded within U.S. Pharmaceutical. The corresponding liability was included within “Other accrued liabilities” in the Consolidated Balance Sheet. On October 30, 2024, the U.S. District Court for the District of New Mexico granted preliminary approval to the proposed settlement, pursuant to which the Company placed approximately $149 million into escrow on November 27, 2024. On March 4, 2025. the Court granted final approval to the settlement, which became effective on April 4, 2025. The escrow payment was presented as restricted cash within “Prepaid expenses and other” in the Company’s Consolidated Balance Sheet as of March 31, 2025.
With respect to the third-party payors, for the year ended March 31, 2025, the Company recorded a charge of $114 million within “Claims and litigation charges, net” in the Consolidated Statement of Operations to reflect the Company’s portion of the settlement with representatives of a nationwide group of certain third-party payors, of which $57 million was recorded within Corporate expenses, net and U.S. Pharmaceutical, respectively. The corresponding liability was included within “Other accrued liabilities” in the Consolidated Balance Sheet. On January 15, 2025, the U.S. District Court for the Northern District of Ohio overruled objections to the settlement and granted final approval to the settlement, pursuant to which the Company placed approximately $114 million into escrow on February 12, 2025. An insurer that objected to the settlement has appealed, and, as a result of the appeal, the settlement has not become effective.

FINANCIAL NOTES (Continued)
The Company’s estimated accrued liability for the above-described opioid-related claims of U.S. governmental entities, including Native American tribes, and certain non-governmental plaintiffs, including a settlement with certain third-party payors and a nationwide class of acute care hospitals, was as follows:

(In millions) | March 31, 2025 |  | March 31, 2024 |  |  |  |
Current litigation liabilities (1) | $ | 776 |  |  | $ | 665 |  |  |  |  |
Long-term litigation liabilities | 5,601 |  |  | 6,113 |  |  |  |  |
Total litigation liabilities | $ | 6,377 |  |  | $ | 6,778 |  |  |  |  |

(1)These amounts, recorded in “Other accrued liabilities” in the Consolidated Balance Sheets, are the amounts estimated to be paid within the next twelve months following each respective period end date.
During the year ended March 31, 2025, 2024, and 2023, the Company made payments totaling $515 million, $544 million, and $1.1 billion, respectively, associated with the Settlement and the separate settlement agreements for opioid-related claims of participating states, subdivisions, and Native American tribes discussed above.
Canadian Plaintiff Claims
The Company and its Canadian affiliate are also defendants in four opioid-related cases pending in Canada. These cases involve the claims of the provincial governments, municipal governments, a group representing indigenous people, as well as one case brought by an individual.
Defense of Opioids Claims
The Company believes it has valid legal defenses in all opioid-related matters, including claims not covered by settlement agreements, and it intends to mount a vigorous defense in such matters. Other than the accruals described above, the Company has not concluded a loss is probable in any of the matters; nor is any possible loss or range of loss reasonably estimable. An adverse judgment or negotiated resolution in any of these matters could have a material adverse impact on the Company’s financial position, cash flows or liquidity, or results of operations.
Qui Tam Litigation
On August 8, 2018, the Company was served with a qui tam complaint pending in the United States District Court for the District of Massachusetts alleging that the Company violated the federal False Claims Act and various state false claims acts due to the alleged failure of the Company and other defendants to report providers who were engaged in diversion of controlled substances. United States ex rel. Manchester v. Purdue Pharma, L.P., et al., Case No. 1-16-cv-10947. On August 22, 2018, the United States filed a motion to dismiss. The relator died, and on February 25, 2019 the court entered an order staying the matter until a proper party can be substituted, and providing that if no party is substituted within 90 days of February 25, 2019, the case would be dismissed. In April 2019, the widow of the relator filed a motion to substitute their daughter as the relator; the United States and defendants opposed this substitution request. The motion remains pending and the case remains stayed.

The complaint seeks relief under the False Claims Act including damages, treble damages, civil penalties, attorney fees, and costs of suit.
Government Subpoenas and Investigations
From time to time, the Company receives subpoenas or requests for information from various governmental agencies. The Company generally responds to such subpoenas and requests in a cooperative, thorough, and timely manner. These responses sometimes require time and effort and can result in considerable costs being incurred by the Company. Such subpoenas and requests can lead to the assertion of claims or the commencement of civil or criminal legal proceedings against the Company and other members of the healthcare industry, as well as to settlements of claims against the Company. The Company responds to these requests in the ordinary course of business. The following are examples of the type of subpoenas or requests the Company receives from time to time.
In July 2024, the United States Department of Justice served a Civil Investigative Demand issued pursuant to the False Claims Act on the Company seeking documents and information related to administration of copay coupon programs associated with certain Sun Pharmaceutical Industries Inc. drugs.

State Opioid Statutes
In April 2018, the State of New York Opioid Stewardship Act (“OSA”) imposed an aggregate $100 million annual surcharge for 2017 and 2018 on all manufacturers and distributors licensed to sell or distribute opioids in New York. In December 2021, the Company paid $26 million for the 2017 OSA surcharge assessment. On May 18, 2022, the Company filed a lawsuit in New York state trial court challenging the constitutionality of the OSA. In November 2022, the Company received a 2018 OSA surcharge assessment of approximately $42 million. On December 14, 2022, the state court ruled that the OSA is constitutional. The Appellate Division subsequently ruled that the 2017 assessment was unconstitutional, but that the 2018 assessment was proper. The Company has paid $42 million for the 2018 OSA surcharge assessment. The Company’s OSA challenge was pending before the New York Supreme Court. On March 31, 2025, The State of New York agreed to pay the Company $28 million to settle the matter, subject to the availability of appropriations. The Company has not recorded a receivable for this recovery.
Environmental Matters
Primarily as a result of the operation of the Company’s former chemical businesses, which were fully divested by 1987, the Company is involved in various matters pursuant to environmental laws and regulations. The Company has received claims and demands from governmental agencies relating to investigative and remedial actions purportedly required to address environmental conditions alleged to exist at four sites where it, or entities acquired by it, formerly conducted operations and the Company, by administrative order or otherwise, has agreed to take certain actions at those sites, including soil and groundwater remediation.
Based on a determination by the Company’s environmental staff, in consultation with outside environmental specialists and counsel, the current estimate of the Company’s probable loss associated with the remediation costs for these four sites is $25 million, net of amounts anticipated from third parties. The $25 million is expected to be paid out between April 2025 and March 2055. The Company has accrued $25 million for the estimated probable loss for these environmental matters in its Consolidated Balance Sheet as of March 31, 2025.
The Company has been designated as a Potentially Responsible Party (“PRP”) under the Superfund law for environmental assessment and cleanup costs as the result of its alleged disposal of hazardous substances at 14 sites. With respect to these sites, numerous other PRPs have similarly been designated and while the current state of the law potentially imposes joint and several liabilities upon PRPs, as a practical matter, costs of these sites are typically shared with other PRPs. For one such site, the Company was one of multiple recipients of a New Jersey Department of Environmental Protection directive and a separate U.S. Environmental Protection Agency (“EPA”) directive concerning natural resources damages to the Passaic River associated with the Company’s Newark, New Jersey facility. In March 2016, the EPA selected a preferred remedy for this Lower Passaic River site with an estimated cost of approximately $1.4 billion. In December 2022, the Company entered into a Consent Decree with the EPA that is currently pending approval by the U.S. District Court for the District of New Jersey and would require the Company to pay $3 million, for which the Company maintained an escrow deposit as of March 31, 2025. Accordingly, the Company’s estimated probable loss at the remaining 13 sites is approximately $23 million, which has been accrued for in the Consolidated Balance Sheet as of March 31, 2025.
Value Added Tax Assessments
The Company operates in various countries outside the U.S. which collect value added taxes (“VAT”). The determination of the manner in which a VAT applies to the Company’s foreign operations is subject to varying interpretations arising from the complex nature of the tax laws. The Company has received assessments for VAT which are in various stages of appeal. The Company disagrees with these assessments and believes that it has a strong legal argument to defend its tax positions. Certain VAT assessments relate to years covered by an indemnification agreement. Due to the complex nature of the tax laws, it is not possible to estimate the outcome of these matters. However, based on currently available information, the Company believes the ultimate outcome of these matters will not have a material adverse effect on its financial position, cash flows or results of operations.

Antitrust Settlements
Numerous lawsuits have been filed against certain pharmaceutical manufacturers alleging that the manufacturer, by itself or in concert with others, took improper actions to delay or prevent generic drugs from entering the market. These lawsuits are sometimes brought as class actions on behalf of those who purchased directly from pharmaceutical manufacturers, including the Company. The Company does not recognize such amounts until received. In certain cases the Company is also named as a plaintiff. Some of these lawsuits have settled in the past with the Company receiving proceeds, including $444 million, $244 million, and $129 million in fiscal 2025, fiscal 2024, and fiscal 2023, respectively, which were included in “Cost of sales” in the Consolidated Statements of Operations.
Other Matters
The Company is involved in various other litigation, governmental proceedings, and claims, not described above, that arise in the normal course of business. While it is not possible to determine the ultimate outcome or the duration of such litigation, governmental proceedings, or claims, the Company believes, based on current knowledge and the advice of counsel, that such litigation, proceedings, and claims will not have a material impact on the Company’s financial position or results of operations.
18. Stockholders' Equity (Deficit)
Each share of the Company’s outstanding common stock is permitted one vote on proposals presented to stockholders and is entitled to participate equally in any dividends declared by the Board.
In July 2024, the Company’s quarterly dividend was raised from $0.62 to $0.71 per share of common stock for dividends declared on or after such date by the Board. The Company declared regular cash dividends of $2.75, $2.40, and $2.09 per share for the years ended March 31, 2025, 2024, and 2023, respectively. The Company anticipates that it will continue to pay quarterly cash dividends in the future. However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon the Company’s future earnings, financial condition, capital requirements, legal requirements, and other factors.
Share Repurchase Plans
The Board has authorized the repurchase of common stock. The Company may repurchase common stock from time-to-time through open market transactions, privately negotiated transactions, accelerated share repurchase programs, or by combinations of such methods, any of which may use pre-arranged trading plans that are designed to meet the requirements of Rule 10b5-1(c) of the Securities Exchange Act of 1934 (“Exchange Act”). The timing of any repurchases and the actual number of shares repurchased will depend on a variety of factors, including our stock price, corporate and regulatory requirements, tax implications, restrictions under our debt obligations, other uses for capital, impacts on the value of remaining shares, cash generated from operations, and market and economic conditions.
Effective January 1, 2023, the Company’s repurchase of common stock, adjusted for allowable items, are subject to a 1% excise tax as a result of the Inflation Reduction Act of 2022. Excise taxes incurred on share repurchases of an entity’s own common stock are direct and incremental costs to purchase treasury stock, and accordingly are included in the total cost basis of the common stock acquired and reflected as a reduction of stockholders’ equity within “Treasury shares” in the Company’s Consolidated Balance Sheets and Consolidated Statements of Stockholders’ Deficit. Excise taxes do not reduce the Company’s remaining authorization for the repurchase of common stock. Excise taxes of $26 million and $25 million were accrued for shares repurchased during the year ended March 31, 2025 and 2024, respectively. On October 30, 2024, the company made a payment of $25 million for fiscal 2024 excise taxes previously accrued. As of March 31, 2025 and March 31, 2024, the amount accrued for excise taxes was $26 million and $25 million, respectively, within “Other accrued liabilities” in the Company’s Consolidated Balance Sheets.

In fiscal 2025, the U.S pharmaceutical sales to one of the Company’s equity method investees totaled $1.1 billion. Trade receivables related to transactions from this investee were $313 million as of March 31, 2025. In fiscal 2024, the Company’s investment in this entity was not accounted for under the equity method and, as a result, was not classified as a related party.
20. Segments of Business
The Company reports its financial results in four operating and reportable segments: U.S. Pharmaceutical, RxTS, Medical-Surgical Solutions, and International. The organizational structure also includes Corporate, which consists of income and expenses associated with administrative functions and projects, and the results of certain investments and operations. The factors for determining the segments include the manner in which management evaluates the performance of the Company combined with the nature of the individual business activities. The Company evaluates the performance of its operating segments on a number of measures, including revenues and operating profit (loss) before interest expense and income taxes.
The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer. The CODM uses operating profit (loss) before interest expense and income taxes to assess performance and allocate resources for each reportable segment during the Company’s annual long-term planning process and through quarterly operating reviews focused on each segment’s results compared to the budget and rolling forecast. The CODM is regularly provided with budgeted or forecasted expense information for the segment and also uses consolidated expense information. Assets by segment are not a measure used to assess the performance of the Company by the CODM and thus are not reported in our disclosures.
The U.S. Pharmaceutical segment distributes branded, generic, specialty, biosimilar and over-the-counter pharmaceutical drugs, and other healthcare-related products in the U.S. This segment also provides practice management, technology, clinical support, and business solutions to community-based oncology and other specialty practices. In addition, the segment sells financial, operational, and clinical solutions to pharmacies (retail, hospital, alternate sites) and provides consulting, outsourcing, technological, and other services.
The RxTS segment helps solve medication access, affordability, and adherence challenges for patients by working across healthcare to connect patients, pharmacies, providers, pharmacy benefit managers, health plans, and biopharma companies. RxTS serves our biopharma and life sciences partners, delivering innovative solutions that help people get the medicine they need to live healthier lives. RxTS offers technology services, which includes electronic prior authorization, prescription price transparency, benefit insight, and dispensing support services, in addition to third-party logistics and wholesale distribution support designed to benefit stakeholders.
The Medical-Surgical Solutions segment provides medical-surgical supply distribution, logistics, and other services to healthcare providers, including physician offices, surgery centers, nursing homes, hospital reference labs, and home health care agencies. This segment offers national brand medical-surgical products as well as McKesson’s own line of high-quality products through a network of distribution centers in the U.S.

Insider Trading Policies and Procedures
We are committed to fostering a culture of compliance, ethics, and regulatory excellence. In furtherance of that commitment, the Company maintains an insider trading compliance program consisting of multiple integrated policies, procedures, controls, and practices that, together, represent our systematic approach to facilitating the oversight, management, and mitigation of insider trading risks across our organization. The foundation of this program is a framework of insider trading policies and procedures (“Insider Trading Policy Framework”) we have adopted applicable to our directors, officers, and employees, as well as the Company itself, which governs the purchase, sale, and other disposition of the securities of the Company and other organizations, including our business partners. We believe the Insider Trading Policy Framework is reasonably designed to promote compliance with insider trading laws, rules, and regulations, and the listing standards applicable to us. Copies of the various policies and procedures comprising our Insider Trading Policy Framework are filed as Exhibits 19.1 through 19.5 to this Annual Report on Form 10-K.
We apply aspects of the Insider Trading Policy Framework commensurate with our assessment of the varying insider trading risks facing the Company and its workforce. The Insider Trading Policy Framework’s general policies and procedures, together with the insider trading compliance standards in the Code of Conduct, cover all of our directors and employees and provide broad prohibitions against the illegal and unauthorized use and disclosure of material non-public information (“MNPI”). The Insider Trading Policy Framework also contains supplemental targeted policies and procedures for individuals whose roles and functions present heightened risk of access to, and misuse of, MNPI. These separate policies and procedures subject directors, designated officers for purposes of Section 16 of the Exchange Act, and certain other employees who are
125

Table of Contents
McKESSON CORPORATION
likely to be aware of potential MNPI (collectively, “Designated Insiders”) to additional trading restrictions, which may limit trading in the Company’s securities to defined trading window periods or upon pre-approval by the Company’s securities counsel, or both. The Insider Trading Policy Framework generally permits, however, trading by the Company and its personnel pursuant to a trading plan that is designed to meet the requirements of Rule 10b5-1 of the Exchange Act and the Insider Trading Policy Framework.
The Company reinforces the Insider Trading Policy Framework with similarly-tailored periodic training and compliance reminders. Insider trading compliance is part of our Code of Conduct training that is required for all employees during the onboarding process and on an annual basis thereafter, and we provide supplemental training to Designated Insiders.
The Chief Legal Officer is principally responsible for designing and implementing our insider trading compliance program and risk management strategy. The Chief Legal Officer and other members of our general counsel organization work collaboratively across the enterprise, including in coordination with our global corporate reporting and investor relations functions, to administer the program and otherwise assist senior leadership in monitoring and mitigating our insider trading risks. We review and refresh the program as needed, considering developments in insider trading laws, emerging risk areas, and policy benchmarks.
A committee of our Board periodically reviews our Insider Trading Policy Framework and related compliance and risk management measures to assist the Board in its oversight of the Company’s compliance with legal and regulatory requirements and risk management.
