PMV Pharmaceuticals, Inc. New Standards Disclosure

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amended guidance enhances income tax disclosures primarily related to the effective tax rate reconciliation and income taxes paid information. This guidance requires disclosure of specific categories in the effective tax rate reconciliation and additional information on reconciling items meeting a quantitative threshold. In addition, the amended guidance requires disaggregating income taxes paid (net of refunds received) by federal, state, and foreign taxes. It also requires disaggregating individual jurisdictions in which income taxes paid (net of refunds received) are equal to or greater than 5 percent of total income taxes paid (net of refunds received). The amended guidance is effective for annual periods beginning after December 15, 2024. We adopted this guidance prospectively for the annual period ending December 31, 2025. For additional information, see “Note 9 — Income Taxes.”

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”. This amended guidance requires disaggregation of specific expense categories in the notes to the financial

statements and a qualitative description of the remaining expense amounts not separately disaggregated. This standard becomes effective for reporting companies with annual reporting periods beginning after December 15, 2026, and requires prospective application with an option to apply it retrospectively. The Company anticipates adopting this standard in its Annual Report on Form 10-K for the year ending December 31, 2027. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.
