Accounting Policies [Abstract]  
Significant Accounting Policies 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.
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:

Total receivables26,143 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.
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:

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.
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.
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.
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.
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,” for 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.
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 Disclosures. 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.

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.

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.
The purchase price allocation included acquired identifiable intangible assets of $177 million, primarily representing customer relationships as well as trademarks and trade names with a weighted average amortization period of 17 years, and goodwill of $113 million. 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:

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.

Share-Based Compensation

Mar. 31, 2025
Share-Based Payment Arrangement [Abstract]  
Share-Based Compensation 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.”
Impact on Net Income
The components of share-based compensation expense and related tax benefits were as follows:

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.
The weighted-average assumptions used in the Monte Carlo valuations were as follows:

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.

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 Company assesses the available positive and negative evidence to determine whether deferred tax assets are more likely than not to be realized. As a result of this assessment, valuation allowances have been recorded on certain deferred tax assets in various tax jurisdictions. The valuation allowances were approximately $644 million and $653 million in fiscal 2025 and fiscal 2024, respectively, and primarily relate to net operating and capital losses.
The Company has federal, state, and foreign net operating loss carryforwards of $40 million, $4.1 billion, and $1.3 billion at March 31, 2025, respectively. Federal and state net operating losses will expire at various dates from 2026 through 2045. Substantially all its foreign net operating losses have indefinite lives. In addition, the Company has foreign capital loss carryforwards of $1.3 billion with indefinite lives.
The following table summarizes the activity related to the Company’s gross unrecognized tax benefits for the last three fiscal years:

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.

Noncontrolling Interest [Abstract]  
Noncontrolling Interests 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:

Earnings Per Share [Abstract]  
Earnings Per Common Share 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.
The computations for basic and diluted earnings or loss per common share were as follows:

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.
The annual impairment testing performed for fiscal 2025, fiscal 2024, and fiscal 2023 did not indicate any impairment of goodwill.

Long-Term Debt
The Company’s long-term debt includes both U.S. dollar and foreign currency-denominated borrowings. At March 31, 2025 and 2024, $5.7 billion and $5.6 billion, respectively, of total debt was outstanding, of which $1.2 billion and $50 million, respectively, was included under the caption “Current portion of long-term debt” in the Company’s Consolidated Balance Sheets.
Public Offerings
On September 10, 2024, the Company completed a public offering of 4.25% Notes due September 15, 2029 in a principal amount of $500 million (the “2029 Notes”). Interest on the 2029 Notes is payable semi-annually on March 15th and September 15th of each year, commencing on March 15, 2025. Proceeds received from the issuance of the 2029 Notes, net of discounts and offering expenses, were $496 million. The Company utilized the net proceeds from the offering of the 2029 Notes together with cash on hand to redeem its $500 million outstanding principal amount of 5.25% Notes due February 15, 2026 (the “2026 Notes”), which became callable on or after February 15, 2024, prior to maturity at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest through the redemption date. The total loss recognized on the debt extinguishment of the 2026 Notes described above for the year ended March 31, 2025 was not material and is included within “Interest expense” in the Company’s Consolidated Statements of Operations.
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.

Variable Interest Entities

Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract]  
Variable Interest Entities 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.

Pension Benefits 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:

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 $19 million at March 31, 2025 and 2024. Funding obligations for its plans vary based on the laws of each jurisdiction.
Expected benefit payments are based on the same assumptions used to measure the benefit obligations and include estimated future employee service. Expected benefit payments for the Company’s pension plans were as follows:
(In millions)Expired Benefit Payments
Fiscal 2026$
Fiscal 2027$
Fiscal 2028$
Fiscal 2029$
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:

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:

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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Hedging Activities 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.
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.
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.

Fair Value Disclosures [Abstract]  
Fair Value Measurements 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.
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, 2025March 31, 2024
(In millions)Carrying ValueFair ValueCarrying ValueFair 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.

Financial Guarantees And Warranties [Abstract]  
Financial Guarantees And Warranties 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:

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.

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingent Liabilities 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.
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.
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, 2025March 31, 2024
Current litigation liabilities (1)
$776 $665 
Long-term litigation liabilities5,601 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.
Other Litigation and Claims
On or about April 25, 2018, a second amended qui tam complaint filed in the U.S. District Court for the Eastern District of New York was served on McKesson Corporation, McKesson Specialty Care Distribution Corporation, McKesson Specialty Distribution LLC, McKesson Specialty Care Distribution Joint Venture, L.P., Oncology Therapeutics Network Corporation, Oncology Therapeutics Network Joint Venture, L.P., US Oncology, Inc., and US Oncology Specialty, L.P. by Omni Healthcare, Inc. as relator, purportedly on behalf of the United States and 33 cities and states alleging that from 2001 through 2010 the defendants repackaged and sold single-dose syringes of oncology medications in a manner that violated the federal False Claims Act and various state and local false claims statutes, and seeking damages, treble damages, civil penalties, attorneys’ fees and costs of suit, all in unspecified amounts.

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.
In March 2025, the United States Department of Justice served a Civil Investigative Demand issued pursuant to the False Claims Act on NDCHealth Corporation, a subsidiary of the Company, seeking documents and information related to cybersecurity requirements in contracts or sub-contracts with the federal government.
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.

Stockholders' Equity (Deficit)

Stockholders' Equity Note [Abstract]  
Stockholders' Equity (Deficit) 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.

Segment Reporting [Abstract]  
Segments of Business 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.
The International segment includes the Company’s operations in Canada and Norway, bringing together non-U.S.-based drug distribution services, specialty pharmacy, retail, and infusion care services. The Company’s Canadian operations deliver medicines, supplies, and information technology solutions throughout Canada and included Rexall Health retail pharmacies. The Company’s Norwegian operations provide distribution and services to wholesale and retail customers in Norway where it owns, partners, or franchises with retail pharmacies. During fiscal 2025, the Company completed the previously announced transaction to sell the Canadian retail disposal group. During fiscal 2023, the Company completed the divestitures of the U.K. disposal group in April 2022, and the E.U. disposal group in October 2022. Refer to Financial Note 2, “Business Acquisitions and Divestitures,” for more information related to these divestitures.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
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.
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.
Both 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, see “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.

Significant Accounting Policies (Policies)
12 Months Ended
Mar. 31, 2025
Accounting Policies [Abstract]  
Basis of Presentation
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
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
Reclassifications: Certain prior period amounts have been reclassified to conform to the current year presentation.
Use of Estimates
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
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
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 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
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.
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.
Concentrations of Credit Risk and Receivables
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: 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.
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
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
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: 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.
Leases
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: 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.
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
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
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
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 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.
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 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
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
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: 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.
Foreign Currency Translation
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: 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.
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.
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.
Comprehensive Income (Loss) 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: 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.
Share-Based Compensation
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
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,” for additional information related to controlled substances claims to which the Company is a party.
Restructuring Charges
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
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.
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
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 and Recently Issued Accounting Pronouncements Not Yet Adopted
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 Disclosures. 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.
Fair Value
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.
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.
