Description of Business, Basis of Presentation and Consolidation and Significant Accounting Policies	Description of Business, Basis of Presentation and Consolidation and Significant Accounting Policies Description of business BeOne Medicines Ltd. (the “Company”, “BeOne”, “it”, “its”), formerly known as BeiGene, Ltd., is a global oncology company redomiciled in Switzerland during the second quarter of 2025, that is discovering and developing innovative treatments that are more affordable and accessible to cancer patients worldwide. The redomiciliation to Switzerland did not change the accounting basis under U.S. generally accepted accounting principles (“GAAP”) of any of the Company’s consolidated assets, liabilities, equity, or any previous results of operations or cash flows. In connection with the redomiciliation, ordinary shares held by the Company or one of its controlled subsidiaries immediately prior to the effective date of the redomiciliation will be part of the Company’s issued share capital and be considered own ordinary shares of the Company, or “treasury shares”, under Swiss law. See BeiGene, Ltd.’s final prospectus filed with the U.S. Securities and Exchange Commission pursuant to Rule 424(b)(3) on March 10, 2025 for a full description of the changes related to the Company’s ordinary shares resulting from the redomiciliation to Switzerland. Since its inception in 2010, the Company has become a fully integrated global organization with more than 11,000 employees worldwide. Basis of presentation and consolidation The accompanying condensed consolidated balance sheet as of June 30, 2025, the condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2025 and 2024, the condensed consolidated statements of cash flows for the six months ended June 30, 2025 and 2024, and the condensed consolidated statements of shareholders’ equity for the three and six months ended June 30, 2025 and 2024, and the related footnote disclosures are unaudited. The accompanying unaudited interim condensed consolidated financial statements were prepared in accordance with U.S. GAAP, including guidance with respect to interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the “Annual Report”). The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all normal recurring adjustments, necessary to present a fair statement of the results for the interim periods presented. Results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results expected for the full fiscal year or for any future annual or interim period. The unaudited interim condensed consolidated financial statements include the financial statements of the Company and its subsidiaries. All significant intercompany transactions and balances between the Company and its subsidiaries are eliminated upon consolidation. Use of estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Areas where management uses subjective judgment include, but are not limited to, estimating the useful lives of long-lived assets, estimating variable consideration in product sales and collaboration revenue arrangements, identifying separate performance obligations and the standalone selling price of each performance obligation in the Company’s revenue arrangements, assessing the impairment of long-lived assets, valuation and recognition of share-based compensation expenses, realizability of deferred tax assets, estimating uncertain tax positions, valuation of inventory, estimating the allowance for credit losses, determining defined benefit pension plan obligations, measurement of right-of-use assets and lease liabilities, and the fair value of financial instruments. Management bases the estimates on historical experience, known trends and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities and reported amounts of revenues and expenses. Actual results could differ from these estimates. Recent accounting pronouncements New accounting standards which have not yet been adopted In November 2024, the FASB issued Accounting Standards Update (“ASU”) 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This update requires that at each interim and annual reporting period public entities disclose (1) the amounts of purchases of inventory, employee compensation, depreciation, amortization, and depletion in commonly presented expense captions; (2) certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements; (3) a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively; and (4) the total amount of selling expenses and, in annual reporting periods, the definition of selling expenses. In January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. This update clarifies that ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact on its financial statements of adopting this guidance. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update requires that public entities on an annual basis, (1) in the rate reconciliation, disclose specific categories and provide additional information for reconciling items that meet a quantitative threshold; (2) about income taxes paid, disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and by individual jurisdiction in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received); and (3) disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) disaggregated by federal, state, and foreign. This update is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. This guidance should be applied on a prospective basis. Retrospective application is permitted. The Company does not expect that the adoption of ASU 2023-09 will have a significant impact on the Company’s consolidated financial statements as the standard does not change the recognition or measurement of current and deferred income taxes and is currently evaluating the impact on the income tax disclosures. Significant accounting policies For a more complete discussion of the Company’s significant accounting policies and other information, the unaudited interim condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report for the year ended December 31, 2024. There have been no material changes to the Company’s significant accounting policies as of and for the six months ended June 30, 2025, as compared to the significant accounting policies described in the Annual Report.
