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 March 31, 2026 and December 31, 2025 and the results of operations and cash flows for the three months ended March 31, 2026 and 2025. 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, 2025 included in the 2025 Form 10-K. 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 the Company's 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.

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 September 2025, the FASB issued amended guidance to refine the scope of derivative accounting and clarify the accounting for share-based noncash consideration from a customer in a revenue contract. Among other provisions, the amendment excludes from derivative accounting non-exchange-traded contracts with underlyings that are based on operations or activities specific to one of the parties in the contract. BMS adopted the new guidance prospectively, beginning on January 1, 2026. The adoption of this guidance did not have an impact on the Company's consolidated financial statements for prior transactions; however, the impact in subsequent periods will be dependent upon the nature of future business development activities.

In September 2025, the FASB issued amended guidance on internal-use software. The guidance clarifies disclosure requirements and establishes new capitalization criteria based on management's authorization and funding commitment as well as the probability that a project will be completed and used for its intended function. The amended guidance is effective for annual periods beginning after December 15, 2027 and interim periods within those annual periods. Early adoption is permitted. The Company is assessing the potential impact of the amended standard.

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.
