Q32 Bio Inc. New Standards Disclosure

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are 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.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280)—Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The amendments in this update improve reportable segment disclosure requirements through enhanced disclosures about significant segment expenses. All disclosure requirements of the update are required for entities with a single reportable segment. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and should be applied on a retrospective basis to all periods presented. The Company adopted this standard as of January 1, 2024. The Company determined that adopting the amendments in ASU 2023-07 had no impact on the Company’s reportable segment identified and additional required disclosures have been included.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740)—Improvements to Income Tax Disclosures (“ASU 2023-09”).

For public companies, the amendments are effective for annual periods beginning after December 15, 2024, and should be applied prospectively. The Company adopted this standard as of January 1, 2025. The Company determined that the effects of adopting the amendments in ASU 2023-09 had no impact on its consolidated financial position and the results of its operations and additional required disclosures have been included.
