MCKESSON CORP

14. Hedging Activities

In the normal course of business, the Company is exposed to interest rate and foreign currency exchange rate fluctuations. At times, the Company limits these risks through the use of derivatives as described below. In accordance with the Company’s policy, derivatives are only used for hedging purposes. The Company does not use derivatives for trading or speculative purposes. The Company uses various counterparties for its derivative contracts to minimize the exposure to credit risk, but does not anticipate non-performance by these parties.

Foreign Currency Exchange Risk

The Company conducts its business worldwide in U.S. dollars and the functional currencies of its foreign subsidiaries, including Canadian dollars, Euro, and British pounds sterling. Changes in foreign currency exchange rates could have a material adverse impact on the Company’s financial results that are reported in U.S. dollars. The Company is also exposed to foreign currency exchange rate risk related to its foreign subsidiaries, including intercompany loans denominated in non-functional currencies. The Company has certain foreign currency exchange rate risk programs that use foreign currency forward contracts and cross-currency swaps. These forward contracts and cross-currency swaps are generally used to offset the potential income statement effects from intercompany loans and other obligations denominated in non-functional currencies. These programs reduce but do not entirely eliminate foreign currency exchange rate risk.

Interest Rate Risk

The Company has exposure to changes in interest rates, and it utilizes risk programs which use interest rate swaps to hedge the changes in debt fair values caused by fluctuations in benchmark interest rates. The Company also enters into forward contracts to hedge the variability of future benchmark interest rates on any planned bond issuances. These programs reduce but do not entirely eliminate interest rate risk.

Derivative Instruments

At March 31, 2026 and 2025, the notional amounts of the Company’s outstanding derivatives were as follows:

(1)The maturity date reflected is for outstanding derivatives as of March 31, 2026.

(2)There was no ineffectiveness in these hedges for the years ended March 31, 2026, 2025, and 2024.

(3)The Company agreed with third parties to exchange fixed interest payments in one currency for fixed interest payments in another currency at specified intervals and to exchange principal in one currency for principal in another currency, calculated by reference to agreed-upon notional amounts.

(4)Represents cross-currency fixed-to-fixed interest rate swaps to mitigate the foreign currency exchange fluctuations on its foreign currency-denominated notes.

(5)Represents fixed-to-floating interest rate swaps to hedge the changes in fair value caused by fluctuations in the benchmark interest rates.

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 cross-currency swaps and restructuring existing cross-currency swaps. As of March 31, 2026 and 2025, the outstanding notional amount of cross- currency swaps was C$6.5 billion.

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. 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. 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 and losses from the changes in the Company’s fair value hedges recorded in earnings were largely offset by the gains and 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 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 loss.

During fiscal 2023, the Company entered into floating interest rate swaps designated as fair value hedges 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 Company’s debt obligations. The changes in the fair value of these derivatives are recorded in “Interest expense” in the Consolidated Statements of Operations.

During the second quarter of fiscal 2026, the Company settled €600 million of fair value cross-currency swaps with original maturity in August 2025, and subsequently entered into €600 million of fair value cross-currency swaps with maturity dates in November 2025. During the third quarter of fiscal 2026, the Company settled the €600 million fair value cross-currency swaps upon repayment of its 1.50% Euro Notes due November 17, 2025. Refer to Financial Note 11, “Debt and Financing Activities,” for additional information on the 1.50% Euro Notes repayment.

Cash Flow Hedges

The Company uses cross-currency swaps to hedge intercompany loans denominated in non-functional currencies to reduce the income statement effects arising from fluctuations in foreign currency exchange rates. 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. 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.

In January 2026, the Company entered into foreign currency forward contracts designated as cash flow hedges with a total notional amount of $791 million to hedge the variability of foreign currency exchange fluctuations related to the sale of the Norway disposal group. These foreign currency forwards were settled in January 2026, and a loss of $30 million was reclassified from accumulated other comprehensive loss and included as a component of the gain recognized on the Norway divestiture as discussed in more detail in Financial Note 2, “Business Acquisitions and Divestitures.” The net gain was reflected within “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations for the year ended March 31, 2026. There wereno gains or losses reclassified from accumulated other comprehensive loss and recorded within “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations for the years ended March 31, 2025, and 2024.

The Company executed a series of forward-starting interest rate swap locks designated as cash flow hedges in fiscal 2025 with a notional amount of $850 million, and in the first quarter of fiscal 2026 with a notional amount of $550 million, for a total of $1.4 billion, to hedge the cash flows associated with certain financing activities. During the first quarter of fiscal 2026, the Company completed a public debt offering of notes, at which point the interest rate swap locks were terminated, and the gains are being amortized to interest expense over the life of the Notes. Refer to Financial Note 11, “Debt and Financing Activities,” for information on the Company’s debt obligations.

In 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. Certain of these foreign currency forwards matured in fiscal 2024 and fiscal 2025, and the remainder were settled in full in fiscal 2026.

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 are recorded directly into earnings within “Selling, distribution, general, and administrative expenses” in the Consolidated Statements of Operations. The Company did not enter into or have any outstanding derivative instruments not designated as hedges during fiscal 2026 and fiscal 2025.
