Bristol-Myers Squibb Company ("BMS", "we", "our", "us" or "the Company") prepared these unaudited consolidated financial statements following the requirements of the SEC and U.S. GAAP for interim reporting. Under those rules, certain footnotes and other financial information that are normally required for annual financial statements can be condensed or omitted. The Company is responsible for the consolidated financial statements included in this Quarterly Report on Form 10-Q, which include all adjustments necessary for a fair presentation of the financial position of the Company as of June 30, 2025 and December 31, 2024 and the results of operations for the three and six months ended June 30, 2025 and 2024, and cash flows for the six months ended June 30, 2025 and 2024. All intercompany balances and transactions have been eliminated. These consolidated financial statements and the related footnotes should be read in conjunction with the audited consolidated financial statements of the Company for the year ended December 31, 2024 included in the 2024 Form 10-K. Beginning in the first quarter of 2025, the financial statement line item "Marketing, Selling and Administrative" included in the 2024 Form 10-K was changed to "Selling, General and Administrative", and such nomenclature continues to be used throughout this Quarterly Report. No changes were made to the corresponding definition. Refer to the Summary of Abbreviated Terms at the end of this Quarterly Report on Form 10-Q for terms used throughout the document.

BMS operates in a single segment engaged in the discovery, development, licensing, manufacturing, marketing, distribution and sale of innovative medicines that help patients prevail over serious diseases. A global research and development organization and supply chain organization are responsible for the discovery, development, manufacturing and supply of products. Regional commercial organizations market, distribute and sell the products. The business is also supported by global corporate staff functions. Consistent with BMS's operational structure, the Chief Executive Officer ("CEO"), as the chief operating decision maker, uses consolidated net income or loss as reported on the income statement when managing and allocating resources at the corporate level. Managing and allocating resources at the global corporate level enables the CEO to assess both the overall level of resources available and how to best deploy these resources across functions, therapeutic areas, regional commercial organizations and research and development projects in line with our overarching long-term corporate-wide strategic goals, rather than on a product or franchise basis. The determination of a single segment is consistent with the financial information regularly reviewed by the CEO for purposes of evaluating performance, allocating resources, setting incentive compensation targets, and planning and forecasting future periods. For further information on product and regional revenue, see “—Note 2. Revenue.”

Revenues, expenses, assets and liabilities can vary during each quarter of the year. Accordingly, the results and trends in these unaudited consolidated financial statements may not be indicative of full year operating results. The preparation of financial statements requires the use of management estimates, judgments and assumptions. The most significant assumptions are estimates used in determining accounting for acquisitions; impairments of intangible assets; charge-backs, cash discounts, sales rebates, returns and other adjustments; legal contingencies; and income taxes. Actual results may differ from estimates.

In November 2024, the FASB issued guidance on income statement disclosures. The guidance aims to provide enhanced disclosures of income statement expenses to improve transparency and provide financial statement users with more detailed information about the nature, amount and timing of expenses impacting financial performance. The new guidance is effective for annual periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted.

In December 2023, the FASB issued amended guidance on income tax disclosures. The guidance is intended to provide additional disaggregation to the effective income tax rate reconciliation and income tax payment disclosures. The amended guidance is effective for annual periods beginning after December 15, 2024.
