Business Overview, Basis of Presentation, and Recently Issued Accounting Standards	1. Business Overview, Basis of Presentation, and Recently Issued Accounting Standards Business Overview Indivior Pharmaceuticals, Inc. and its subsidiaries (together, "Indivior" or the "Company") is the market leader in long-acting injectable medications for opioid use disorder (OUD). The Company's core products include SUBLOCADE (buprenorphine extended-release monthly injection) and SUBOXONE Film (buprenorphine and naloxone sublingual film), both of which are treatments for OUD. Basis of Presentation The accompanying unaudited interim Condensed Consolidated Financial Statements and related notes should be read in conjunction with the audited Consolidated Financial Statements of Indivior Pharmaceuticals, Inc. and its subsidiaries and related notes as contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented. Certain prior‑period amounts have been reclassified to conform to the current‑period presentation. These reclassifications had no impact on previously reported net income, comprehensive income, or cash flows. The accounting policies of the Company are consistent with those disclosed in "Item 1. Financial Statements - Note 2. Summary of Significant Accounting Policies" of the Company's Annual Report on Form 10-K for the year ended December 31, 2025. Columns and rows within tables may not add due to rounding. Percentages and per share data have been calculated using actual, non-rounded figures. Use of Estimates The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported. Significant estimates are used in determining items such as accruals for returns, incentives and rebates, certain accrued expenses, acquisitions, and ongoing litigation. Actual results may differ from those estimates. Recently Adopted Accounting Standards ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, was issued in November 2024 and clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions or debt extinguishments. ASU 2024-04 is effective for annual and interim periods beginning after December 15, 2025. The Company adopted ASU 2024-04 effective January 1, 2026 and applied the guidance on a prospective basis. The adoption of ASU 2024-04 did not have a material impact on the Company's condensed consolidated financial statements. ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets was issued in July 2025 and allows entities to elect a practical expedient that assumes that the current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU No. 2025-05 is effective for annual and interim periods beginning after December 15, 2025. The Company adopted ASU 2025-05 effective January 1, 2026 and applied the guidance on a prospective basis. The adoption of ASU 2025‑05 did not have a material impact on the Company’s condensed consolidated financial statements. ASU 2025‑07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share‑Based Noncash Consideration from a Customer in a Revenue Contract refines the scope of derivative accounting under Topic 815 by introducing a new scope exception for certain contracts or embedded features that are not exchange traded and have underlyings based on the operations or activities specific to one of the parties to the contract. In addition, the ASU clarifies that share‑based noncash consideration received from a customer in exchange for goods or services is initially accounted for under Topic 606, Revenue from Contracts with Customers, unless and until the entity’s right to receive or retain such consideration becomes unconditional. The Company early adopted ASU 2025‑07 effective January 1, 2026 and applied the guidance on a prospective basis. The adoption of ASU 2025‑07 did not have a material impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Standards Not Yet Adopted ASU 2024-03: Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)—Disaggregation of Income Statement Expenses (as clarified by ASU 2025-01) was issued in November 2024, requires disclosure of specified information about certain costs and expenses in the notes to the financial statements and is required to be applied by the Company for annual periods beginning after December 31, 2026 and interim periods beginning after December 15, 2027. As this accounting standard only impacts disclosures, it is not expected to have a material impact on the Company’s financial statements. ASU No. 2025-06, Intangibles-Goodwill and Other-Internal Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software was issued in September 2025 and removes all references to software development project stages. Software capitalization will begin when management has authorized and committed to funding the software project and when it is probable that the project will be completed and the software will be used to perform the function intended. ASU 2025-06 is effective for interim and annual periods beginning after December 15, 2027. The guidance may be applied on a prospective basis, a modified transition approach or a retrospective transition approach and allows for early adoption. Adoption is not expected to have a material impact on the Company's financial statements.
