In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" which provides guidance on the requirements such as the requirement that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. DLH is a public company that reports income tax disclosures and therefore this ASU applies to the Company. ASU 2023-09 is effective for public business entities for fiscal years beginning after December 15, 2024. We will adopt ASU 2023-09 in our Annual Report on Form 10-K for the fiscal year ending September 30, 2026. We are currently evaluating the impacts of the improvements to income tax disclosure.

In March 2024, the Securities and Exchange Commission ("SEC") adopted final rules requiring registrants to provide certain climate-related disclosures in their annual reports and registration statements. In May 2026, the SEC proposed rescinding these rules, and the proposal remains subject to a public comment process and further Commission action. The Company is monitoring these developments and evaluating the potential impact, if any, on its future disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income (Subtopic 220-40): Expense Disaggregation Disclosures. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which clarified the effective date of ASU 2024-03. This guidance enhances transparency in financial reporting by requiring public business entities to disclose disaggregated information about expenses in their financial statements. The guidance mandates disclosure of specific cost components, such as inventory purchases, employee compensation, depreciation, and amortization, within relevant income statement expense captions, along with qualitative descriptions of any remaining other amounts. Entities must also disclose total selling expenses and define these annually. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted, and the guidance may be applied prospectively or retrospectively. We are currently evaluating the impacts of the improvements to our disclosure.
