Item 2.02 | Results of Operations and Financial Condition. |
The information set forth in Item 8.01 is incorporated herein by reference.
Commencing in the second quarter of fiscal 2026, McKesson Corporation (the “Company,” “McKesson,” “we,” “our,” and other similar pronouns) will report financial results across four reportable segments: North American Pharmaceutical, Oncology & Multispecialty, Prescription Technology Solutions, and Medical-Surgical Solutions. Our Norwegian operations will be included in Other. The organizational structure also includes Corporate, which consists of income and expenses associated with administrative functions and projects, and the results of certain investments. These segment changes reflect how our Chief Executive Officer, who is our chief operating decision maker, allocates resources and assesses performance beginning in the second quarter of fiscal 2026. The segment changes did not impact our previously issued consolidated financial statements or our historical earnings per diluted share.
Additional information regarding our reportable segments is as follows:
•North American Pharmaceutical: A newly defined reportable segment combining McKesson’s scaled wholesale drug distribution businesses in the United States and Canada. It delivers best-in-class distribution services to a broad customer base, including retail and community pharmacies, and institutional healthcare providers.
•Oncology & Multispecialty: A newly defined reportable segment that includes a portfolio of integrated solutions across oncology and multispecialty providers and solutions. The segment includes specialty provider solutions, including distribution-related capabilities, such as specialty drug distribution and group purchasing organizations; and Practice management services supporting the largest physician-led, community-based oncology networks. The segment also includes other multispecialty providers, including retina and ophthalmology, and offers clinical trial services, specialty pharmacy solutions, and access to cutting-edge research, along with innovation through technology-driven insights.
•Prescription Technology Solutions: Connects patients, pharmacies, providers, pharmacy benefit managers, health plans, and biopharma through scaled and differentiated networks, improving medication access and affordability, while delivering measurable value to biopharma.
•Medical-Surgical Solutions: Delivers medical-surgical supply distribution, logistics, and other related services to healthcare providers across alternate sites of care. In May 2025, McKesson announced its intention to separate this segment into an independent company.
Our Norwegian distribution and retail operations are included in Other. On August 4, 2025, McKesson entered into a definitive agreement to sell our businesses in Norway. The transaction is subject to customary closing conditions, including receipt of required regulatory approvals.
We are filing supplemental historical financial information by new reportable segment in the exhibit included as Exhibit 99.1 for the fiscal quarters ended June 30, 2024, September 30, 2024, December 31, 2024, March 31, 2025, and June 30, 2025, and for the fiscal years ended March 31, 2025 and 2024. The Company believes the presentation of its historical segment financial information by new reportable segment provides useful supplemental information for investors to better understand the impact of segment changes.
