RHYTHM PHARMACEUTICALS, INC. New Standards Disclosure
Application of New or Revised Accounting Standards
From time to time, new accounting pronouncements are issued by the FASB and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption.
Recently adopted accounting pronouncements
In December 2024, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, or ASU 2023-09. The new guidance requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The amendments in the ASU are intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update are effective for us beginning in fiscal year ending December 31, 2025. The Company has adopted this update on a prospective basis. The adoption of this guidance resulted in expanded disclosures in its consolidated financial statements.
In November 2023, the FASB issued ASU 2023-07 – Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures, which improves segment disclosure requirements, primarily through enhanced disclosure requirements for significant segment expenses. The improved disclosure requirements apply to all public entities that are required to report segment information, including those with only one reportable segment. The Company adopted the guidance in the fiscal year beginning January 1, 2024. There was no impact on the Company’s reportable segments identified and additional required disclosures have been included in Note 15.
Recently issued accounting pronouncements, not yet adopted
In December 2025, the FASB issued ASU 2025-12 “Codification Improvements” to address suggestions received from stakeholders on the Accounting Standards Codification and to make other incremental improvements to U.S. GAAP. The update represents changes to the Codification that clarify, correct errors, or make minor improvements. The amendments make the Codification easier to understand and apply. The guidance is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years. The Company is in the process of evaluating this guidance to determine the impact it may have on its consolidated financial statements.
In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270) Narrow-Scope Improvements.” The amendments in this update provide clarity on interim disclosure requirements and the applicability of Topic 270. The amendments in this update also include a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The amendments in this ASU are required to be adopted for interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is in the process of evaluating this guidance to determine the impact it may have on its consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03 “Income Statement: Reporting Comprehensive Income—Expense Disaggregation Disclosures,” which requires more detailed information about specified categories of expenses (purchases of inventory, employee compensation, depreciation, amortization, and depletion) included in certain expense captions presented on the face of the income statement, as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to all prior periods presented in the financial statements. The Company is in the process of evaluating this guidance to determine the impact it may have on its consolidated financial statements disclosures.

About New Standards Disclosures
New accounting standards disclosures describe recently adopted pronouncements and those not yet effective, along with management's assessment of their expected impact. This section provides an early warning system for upcoming changes to how a company reports its financial results, often years before the new rules take effect.
Key signals: when management describes a not-yet-adopted standard's impact as "material" or "still being evaluated," it signals potential significant changes to reported metrics upon adoption. Watch for standards that affect a company's core operations — for example, revenue recognition changes for software companies or lease accounting changes for retailers with large store footprints. The transition method chosen (full retrospective versus modified retrospective) affects comparability with prior periods. Companies that delay adoption to the latest permitted date may be struggling with implementation complexity. Compare the disclosed impact assessments against peers in the same industry to gauge whether management's expectations are reasonable.
