American Healthcare REIT, Inc. New Standards Disclosure

Recently Issued Accounting Pronouncements

In December 2023, the Financial Accounting Standard Board, or FASB, issued Accounting Standard Update, or ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, or ASU 2023-09, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted and should be applied prospectively; however, retrospective application is permitted. We adopted ASU 2023-09 beginning with this Annual Report on Form 10-K. We provided additional tax disclosures in the notes to our consolidated financial statements and no other changes to our existing disclosures or consolidated financial statements were required as a result of such adoption.

In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, or ASU 2024-03. Further, in January 2025, the FASB issued ASU 2025-01, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, or ASU 2025-01. ASU 2024-03 requires new financial statement disclosure to be provided in the notes to the financial statements in a tabular presentation related to the disaggregation of certain expense captions presented on the face of the income statement within continuing operations that include expense categories such as: (i) purchases of inventory; (ii) employee compensation; (iii) depreciation; and (iv) intangible asset amortization. ASU 2024-03 and ASU 2025-01 are 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 and may be applied retrospectively or prospectively. We are currently evaluating this guidance to determine the impact on our consolidated financial statement disclosures beginning with our 2027 Annual Report on Form 10-K.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity, or ASU 2025-03. ASU 2025-03 amends the guidance Topic 805 and Topic 810, to improve the determination of the accounting acquirer in business combinations involving VIEs. Under the new guidance, entities are required to apply the general principles in Topic 805 to identify the accounting acquirer when the legal acquiree is a VIE that meets the definition of a business, and the transaction is primarily effected by exchanging equity interests. ASU 2025-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted and should be applied prospectively to any acquisition transaction that occurs after the adoption date. We are currently evaluating this guidance to determine the impact on our consolidated financial statement and disclosures beginning with our Quarterly Report on Form 10-Q for the quarterly period ending March 31, 2027.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow Scope Improvements, or ASU 2025-11, to update the guidance in ASC Topic 270, Interim Reporting, by improving navigability of the required interim disclosures, clarifying when that guidance is applicable and adding a principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods beginning after December 15, 2027. Early adoption is permitted and may be applied retrospectively or prospectively. We are currently evaluating this guidance to determine the impact on our consolidated financial statement disclosures beginning with our Quarterly Report on Form 10-Q for the quarterly period ending March 31, 2028.
