| Item 8.01 | Other Events |
|---|
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.

Document
Exhibit 99.1
SUPPLEMENTAL HISTORICAL SEGMENT FINANCIAL INFORMATION
McKesson Corporation (the "Company," "we," or "our") is furnishing to investors supplemental historical financial information by new reportable segment for our quarterly results of fiscal 2025 and first quarter of fiscal 2026 as well as annual results for fiscal 2025 and 2024. We believe the presentation of our historical segment financial information by new reportable segment provides useful supplemental information to investors to better understand the impact of segment changes.
We reassessed our reportable segments following a change in our organizational structure to reflect our continued focus on delivering new and innovative solutions to respond to the evolving needs of the healthcare industry, customers, and patients. In connection with the completion of this change, our operating structure was realigned, and commencing in the second quarter of fiscal 2026, we will report our financial results in four reportable segments on a retrospective basis as follows: North American Pharmaceutical, Oncology & Multispecialty, Prescription Technology Solutions, and Medical-Surgical Solutions. Our operations in Norway will be included in Other on a retrospective basis. The segment changes reflect how our chief operating decision maker allocates resources and assesses performance commencing in the second quarter of fiscal 2026. The segment changes did not impact the previously issued consolidated financial statements nor earnings per common share of McKesson for historical periods.
Exhibit I provides a reconciliation of the Company’s previously reported GAAP segment financial results to Non-GAAP financial results supplemental to our quarterly results of fiscal 2025 and first quarter of fiscal 2026 as well as annual results for fiscal 2025 and 2024.

SUPPLEMENTAL NON-GAAP FINANCIAL INFORMATION
In an effort to provide investors with additional information regarding the Company's financial results as determined by generally accepted accounting principles ("GAAP"), McKesson Corporation (the "Company" or "we") also presents the following Non-GAAP financial measures in this exhibit to Form 8-K.
•Adjusted Segment Operating Profit (Non-GAAP) and Adjusted Segment Operating Profit Margin (Non-GAAP): We define Adjusted Segment Operating Profit as GAAP segment operating profit, excluding amortization of acquisition-related intangibles, transaction-related expenses and adjustments, LIFO inventory-related adjustments, gains from antitrust legal settlements, restructuring, impairment, and related charges, claims and litigation charges, and other adjustments. We define Adjusted Segment Operating Profit Margin as Adjusted Segment Operating Profit (Non-GAAP) divided by GAAP segment revenues.
•Adjusted Corporate Expenses (Non-GAAP): We define Adjusted Corporate Expenses as GAAP corporate expenses, net, excluding transaction-related expenses and adjustments, restructuring, impairment, and related charges, claims and litigation charges, and other adjustments.
•Adjusted Operating Profit (Non-GAAP): We define Adjusted Operating Profit as GAAP income before interest expense and income taxes, excluding amortization of acquisition-related intangibles, transaction-related expenses and adjustments, LIFO inventory-related adjustments, gains from antitrust legal settlements, restructuring, impairment, and related charges, claims and litigation charges, and other adjustments.
The following provides further details regarding the adjustments made to our GAAP financial results to arrive at our Non-GAAP financial measures as defined above:
Amortization of acquisition-related intangibles - Amortization charges for intangible assets directly related to business combinations and the formation of joint ventures.
Transaction-related expenses and adjustments - Transaction, integration and other expenses that are directly related to business combinations, the formation of joint ventures, divestitures, and other transaction-related costs including initial public offering costs. Examples include transaction closing costs, professional service fees, legal fees, severance charges, retention payments and employee relocation expenses, facility or other exit-related expenses, certain fair value adjustments including deferred revenues, contingent consideration and inventory, recoveries of acquisition-related expenses or post-closing expenses, net interest expense impact of hedging foreign currency-denominated notes, bridge loan fees, and gains or losses on business combinations and divestitures of businesses that do not qualify as discontinued operations.
LIFO inventory-related adjustments - LIFO inventory-related non-cash charges or credit adjustments.
Gains from antitrust legal settlements - Net cash proceeds representing the Company’s share of antitrust legal settlements.
Restructuring, impairment, and related charges - Restructuring charges that are incurred for programs in which we change our operations, the scope of a business undertaken by our business units, or the manner in which that business is conducted, as well as long-lived asset impairments. Such charges may include employee severance, retention bonuses, facility closure or consolidation costs, lease or contract termination costs, asset impairments, accelerated depreciation and amortization, and other related expenses. The restructuring programs may be implemented due to the sale or discontinuation of a product line, reorganization or management structure changes, headcount rationalization, realignment of operations or products, integration of acquired businesses, and/or company-wide cost saving initiatives. The amount and/or frequency of these restructuring charges are not part of our underlying business, which include normal levels of reinvestment in the business. Any credit adjustments due to subsequent changes in estimates are also excluded from adjusted results.
Claims and litigation charges - Adjustments to certain of the Company’s reserves, including those related to estimated probable settlements for its controlled substance monitoring and reporting, and opioid-related claims, as well as any applicable income items or credit adjustments due to subsequent changes in estimates. This does not include our legal fees to defend claims, which are expensed as incurred. This also may include charges or credits for general non-operational claims not directly related to our ongoing business.
Other adjustments - The Company evaluates the nature and significance of transactions qualitatively and quantitatively on an individual basis and may include them in the determination of our adjusted results from time to time. While not all-inclusive, other adjustments may include: other asset impairments; gains or losses from debt extinguishment; and other similar substantive and/or infrequent items as deemed appropriate.

SUPPLEMENTAL NON-GAAP FINANCIAL INFORMATION (continued)
The Company believes the presentation of Non-GAAP financial measures provides useful supplemental information to investors with regard to its operating performance, as well as assists with the comparison of its past financial performance to the Company’s future financial results. Moreover, the Company believes that the presentation of Non-GAAP financial measures assists investors’ ability to compare its financial results to those of other companies in the same industry. However, Non-GAAP financial measures used in the press tables may be defined and calculated differently by other companies in the same industry.
The Company internally uses both GAAP and Non-GAAP financial measures in connection with its own financial planning and reporting processes. Management utilizes Non-GAAP financial measures when allocating resources, deploying capital, as well as assessing business performance, and determining employee incentive compensation. Nonetheless, Non-GAAP financial measures disclosed by the Company should not be considered a substitute for, nor superior to, financial results and measures as determined or calculated in accordance with GAAP.
