MCKESSON CORP

Selected Measures of Liquidity and Capital Resources

(1)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 September 30, 2025 and March 31, 2025 included approximately $1.6 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 September 30, 2025 compared to March 31, 2025 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 current portion of long term debt, and an increase in other accrued liabilities. These were partially offset by an increase in inventories, net, and receivables, net, driven by higher sales and timing.

Our debt to capital ratio decreased for the six months ended September 30, 2025 due to net income attributable to McKesson for fiscal 2026 and issuance of new long-term debt, partially offset by share repurchases and dividend payments.

On July 29, 2025, we raised our quarterly dividend from $0.71 to $0.82 per share of common stock. 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.

Redeemable Noncontrolling Interests

During the six months ended September 30, 2025, we initially recognized redeemable noncontrolling interests of $25 million and $700 million related to our acquisition of 80% of PRISM Vision and 70% of Core Ventures, respectively. The balance of redeemable noncontrolling interests is reported at the greater of its carrying value or its maximum redemption value at each reporting date. The 30% minority interest retained by FCS is classified as redeemable noncontrolling interest, with a put option exercisable every five years, subject to a floor of 75% of initial fair value. As a result of the quarterly valuation process, we recorded an adjustment to the redemption value of the redeemable noncontrolling interests of $2 million for PRISM Vision and $45 million for Core Ventures.

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 September 30, 2025 payable under the terms of various settlement agreements for opioid-related claims, are expected to be met by existing cash balances, cash flow from operations, existing credit sources, and future borrowings. Long-term debt markets and commercial paper markets, our primary sources of capital after cash flow from operations, are open and accessible to us should we decide to access those markets. Detailed information regarding our debt and financing activities is included in Financial Note 8, “Debt and Financing Activities,” to the accompanying condensed consolidated financial statements included in this Quarterly 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.
