MCKESSON CORP

We are a diversified healthcare services leader dedicated to advancing health outcomes for patients everywhere. Our teams partner 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.

We report our financial results in four reportable segments: U.S. Pharmaceutical, Prescription Technology Solutions (“RxTS”), Medical-Surgical Solutions, and International. Our organizational structure also includes Corporate, which consists of income and expenses associated with administrative functions and projects, as well as the results of certain investments and operations. The factors for determining the reportable segments include the manner in which management evaluates the performance of the Company combined with the nature of individual business activities. We evaluate the performance of our operating segments on a number of measures, including revenues and operating profit (loss) before interest expense and income taxes.

The following summarizes our four reportable segments. Refer to Financial Note 12, “Segments of Business,” to the accompanying condensed consolidated financial statements included in this Quarterly Report for further information regarding our reportable segments.

•U.S. Pharmaceutical is a reportable segment that distributes branded, generic, specialty, biosimilar, and over-the-counter pharmaceutical drugs, and other healthcare-related products in the United States (“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.

•Prescription Technology Solutionsis a reportable segment that combines automation and our ability to navigate the healthcare ecosystem to connect patients, pharmacies, providers, pharmacy benefit managers, health plans, and biopharma companies to address patients’ medication access, affordability, and adherence challenges. RxTS also offers prescription price transparency, benefit insight, and dispensing support services, as well as third-party logistics and wholesale distribution support across various therapeutic categories and temperature ranges to biopharma customers throughout the product lifecycle.

•Medical-Surgical Solutions is a reportable segment that 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 within the U.S.

•International is a reportable segment that includes our operations in Canada and Norway, bringing together non-U.S.-based drug distribution services, specialty pharmacy, retail, and infusion care services. Our Canadian operations deliver medicines, supplies, and information technology solutions throughout Canada and include Rexall Health retail pharmacies. Our Norwegian operations provide distribution and services to wholesale and retail customers in Norway where we own, partner, or franchise with retail pharmacies. In the second quarter of fiscal 2025, we entered into an agreement to sell our Rexall and Well.ca businesses in Canada (“Canadian retail disposal group”). These divestitures are further described in the “Canadian Divestiture Activities” section below.
