MCKESSON CORP

We expect our available cash generated from operations and our short-term investment portfolio, together with our existing sources of liquidity from our credit facilities, commercial paper program, and other borrowings will be sufficient to fund our short-term and long-term capital expenditures, working capital, and other cash requirements. We remain adequately capitalized, including access to liquidity from our $4.0 billion revolving credit facility and $1.0 billion 364-day credit facility. At September 30, 2025, we were in compliance with all debt covenants, and believe we have the ability to continue to meet our debt covenants in the future.

Operating Activities

Operating activities provided cash of $1.5 billion and $720 million during the six months ended September 30, 2025 and 2024, respectively.

For the six months ended September 30, 2025, net cash used by operating activities increased by $782 million compared to the same prior year period. This increase was primarily due to the following:

•an increase in net cash of $1.2 billion related to accounts receivable is primarily due to favorable timing of collections;

•an increase in cash from other assets and liabilities primarily related to lower contract liability payments; and
