MCKESSON CORP

Share Repurchase Plans

The Board has authorized the repurchase of common stock. We may repurchase common stock from time-to-time through open market transactions, privately negotiated transactions, accelerated share repurchase (“ASR”) programs, or by combinations of such methods, any of which may use pre-arranged trading plans that are designed to meet the requirements of Rule 10b5-1(c) of the 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.

Excise taxes incurred on our share repurchases are direct and incremental costs to purchase treasury stock, and accordingly are included in the total cost basis of the common stock acquired and reflected as a reduction of stockholders’ equity within “Treasury shares” in our Consolidated Balance Sheets and Consolidated Statements of Stockholders’ Deficit. Excise taxes do not reduce our remaining authorization for the repurchase of common stock. Excise taxes of $40 million and $26 million were accrued for shares repurchased during the years ended March 31, 2026 and 2025, respectively. On October 30, 2024, we made a payment of $25 million for fiscal 2024 excise taxes previously accrued. On July 30, 2025, we made a payment of $26 million for fiscal 2025 excise taxes previously accrued. As of March 31, 2026 and March 31, 2025, the amount accrued for excise taxes was $40 million, and $26 million, respectively, within “Other accrued liabilities” in our Consolidated Balance Sheets.

Information regarding the share repurchase activity over the last two fiscal years was as follows:

(2)The number of shares purchased reflects rounding adjustments.

(3)The remaining authorization outstanding for repurchases of common stock excludes $40 million and $26 million of excise taxes incurred on share repurchases for the years ended March 31, 2026 and 2025, respectively.

(4)In July 2024, the Board authorized the Company to repurchase with no expiration date up to an additional $4.0 billion shares of common stock. On April 29, 2026, the Board of Directors approved the Company to repurchase up to an additional $5.0 billion shares of common stock to a total authorization of $7.7 billion of April 2026.

(5)In March 2026, the Company entered into an ASR program with a third-party financial institution to repurchase$2.3 billion of the Company’s common stock. The average price paid per share and total number of shares purchased under this program are estimates based on the initial share purchase price and initial delivery of shares under an ASR agreement and may differ from the average price paid per share and total number of shares purchased under the ASR program upon its final settlement in the first quarter of Fiscal 2027.

Selected Measures of Liquidity and Capital Resources

(1)Based on year-end balances and sales or cost of sales for the last 90 days of the year.

(2)This ratio describes the relationship and changes within our capital resources, and is computed as the sum of total debt divided by the sum of total debt and McKesson stockholders’ deficit, which excludes noncontrolling interests and accumulated other comprehensive loss.

Cash equivalents, which are readily convertible to known amounts of cash, are carried at fair value. Cash equivalents are primarily invested in AAA-rated U.S. government money market funds, short-term deposits with financial institutions, and short-term commercial papers issued by non-financial institutions. Deposits with financial institutions are primarily denominated in U.S. dollars and the functional currencies of our foreign subsidiaries, including Canadian dollars. Deposits could exceed the amounts insured by the Federal Deposit Insurance Corporation in the U.S. and similar deposit insurance programs in other jurisdictions. We mitigate the risk of our short-term investment portfolio by depositing funds with reputable financial institutions and monitoring risk profiles and investment strategies of money market funds.

Our cash and cash equivalents balance as of March 31, 2026 and 2025 included approximately $1.8 billion and $2.9 billion, respectively, of cash held by our subsidiaries outside of the U.S. Our primary intent is to utilize this cash for foreign operations for an indefinite period of time. Although the majority of cash held outside the U.S. is available for repatriation, doing so could subject us to foreign withholding taxes and state income taxes. We may remit foreign earnings to the U.S. to the extent it is tax efficient to do so. We do not anticipate the tax impact from remitting these earnings to be material. Following enactment of the 2017 Tax Cuts and Jobs Act, the repatriation of cash to the U.S. is generally no longer taxable for federal income tax purposes.

Working capital primarily includes cash and cash equivalents, receivables, inventories, and prepaid expenses, net of drafts and accounts payable, short-term borrowings, current portion of long-term debt, current portion of operating lease liabilities, and other accrued liabilities. Our businesses require substantial investments in working capital that are susceptible to large variations during the year as a result of inventory purchase patterns and seasonal demands. Inventory purchase activity is a function of sales activity and other requirements.

Consolidated working capital decreased at March 31, 2026 compared to the prior year primarily due to an increase in drafts and accounts payable from increased purchasing driven by increased sales and timing, a decrease in cash and cash equivalents, an increase in other accrued liabilities, and an increase in the current portion of long term debt. These were partially offset by an increase in receivables, net, and inventories, net, driven by higher sales and timing.

Our debt to capital ratio increased for the year ended March 31, 2026 compared to the prior year primarily due to share repurchases and dividend payments as well as repayments of long-term debt, partially offset by net income attributable to McKesson for fiscal 2026 and issuance of new long-term debt.

On July 29, 2025, we raised our quarterly dividend from $0.71 to$0.82 per share of common stock. Dividends were $3.17 per share in fiscal 2026 and $2.75 per share in fiscal 2025, and we paid total cash dividends of $381 million and $345 million in fiscal 2026 and fiscal 2025, respectively. We anticipate that we will continue to pay quarterly cash dividends in the future. However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon our future earnings, financial condition, capital requirements, legal requirements, and other factors.

FINANCIAL REVIEW (Concluded)

Capital Resources

We fund our working capital requirements primarily with cash and cash equivalents, proceeds from short-term borrowings from our commercial paper issuances, and longer-term credit agreements and debt offerings. Funds necessary for future debt maturities and our other cash requirements, including any future payments that may be made related to our total estimated litigation liability of $5.7 billion as of March 31, 2026 payable under the terms of various settlement agreements for opioid-related claims, are expected to be met by existing cash balances, cash flow from operations, existing credit sources, and future borrowings. Long-term debt markets and commercial paper markets, our primary sources of capital after cash flow from operations, are open and accessible to us should we decide to access those markets. Detailed information regarding our debt and financing activities is included in Financial Note 11, “Debt and Financing Activities,” to the consolidated financial statements included in this Annual Report.

We believe that our future operating cash flow, financial assets, and access to capital and credit markets, including our credit facilities, give us the ability to meet our financing needs for the foreseeable future. However, there can be no assurance that an increase in volatility or disruption in the global capital and credit markets will not impair our liquidity or increase our costs of borrowing.
