Income Taxes In December 2023, the Financial Accounting Standards Board (FASB) issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (ASU 2023-09). Beginning with our 2025 annual reporting, we adopted, through retrospective application, ASU 2023-09, which requires that a public entity disclose specific categories in its annual income tax rate reconciliation table and provide additional qualitative information for reconciling items representing at least 5% of pre-tax income or loss from continuing operations, using the federal statutory tax rate. The standard also requires an annual breakdown of income taxes paid by jurisdiction (i.e., federal, state and foreign), with further disaggregation by jurisdictions representing at least 5% of total income taxes paid.

Segment Reporting In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (ASU 2023-07). Beginning with our 2024 annual reporting, we adopted, through retrospective application, ASU 2023-07, which requires that a public entity disclose, on an interim and annual basis, significant segment expense categories and amounts that are regularly provided to its chief operating decision maker (CODM) and included in each reported measure of segment profit or loss. An entity must also disclose, by reportable segment, the amount and composition of other expenses. The standard requires an entity disclose the title and position of its CODM and explain how the CODM uses these reported measures in assessing segment performance and determining how to allocate resources.

Convertible Instruments Beginning with 2022 interim reporting, we adopted, through retrospective application, ASU No. 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06). ASU 2020-06 requires that instruments which may be settled in cash or stock are presumed settled in stock in calculating diluted earnings per share. Prior to the April 2023 repurchase, settlement of our Series A Cumulative Perpetual Membership Interests in AT&T Mobility II LLC (Mobility preferred interests) could have resulted in additional dilutive impact, the magnitude of which was influenced by the fair value of the Mobility preferred interests and the average AT&T common stock price during the reporting period, which varied from period-to-period (see Note 16).

Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” (ASU 2024-03), which requires that a public entity disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation and (d) intangible asset amortization included in each relevant expense caption presented on the face of the income statement. The standard also requires an entity to disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively as well as disclose the total
amount of selling expenses and, annually, the entity’s definition of selling expenses. ASU 2024-03 will be effective for annual periods beginning after December 15, 2026, with either retrospective or prospective application. The standard allows for early adoption of these requirements; we are currently evaluating the disclosure impacts of our adoption.

Internal-Use Software In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (ASU 2025-06). ASU 2025-06 removes references to prescriptive and sequential software development stages and requires software cost capitalization when management has authorized and committed to funding, and it is probable that the project will be completed, and the software used for its intended function. ASU 2025-06 will be effective for annual reporting periods beginning after December 15, 2027. We are evaluating the impacts of our adoption of ASU 2025-06 and currently do not expect that it will have a material impact on our financial statements.

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.
