Preparation Of Interim Financial Statements	NOTE 1. PREPARATION OF INTERIM FINANCIAL STATEMENTS Basis of Presentation Throughout this document, AT&T Inc. is referred to as “we,” “AT&T” or the “Company.” The consolidated financial statements include the accounts of the Company and subsidiaries and affiliates which we control. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications and technology industries. You should read this document in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2025. The results for the interim periods are not necessarily indicative of those for the full year. These consolidated financial statements include all adjustments that are necessary to present fairly the results for the presented interim periods, consisting of normal recurring accruals and other items. On February 2, 2026, we closed our transaction with Lumen Technologies, Inc. (Lumen) and acquired substantially all of Lumen’s Mass Markets fiber business for $5,756 cash, including purchase price adjustments. The acquisition included customer relationships, which we include with our advanced home internet services, and fiber network assets that were placed in a wholly owned subsidiary, Forged Fiber 37 Services, LLC (Forged Fiber). We plan to sell a controlling interest in Forged Fiber to an equity partner that will co-invest in the ongoing business. As such, Forged Fiber met the criteria of held-for-sale and accordingly is reflected as discontinued operations in the accompanying financial statements. (See Notes 8 and 12) The consolidated financial statements include our controlled subsidiaries, as well as variable interest entities (VIE) where we are deemed to be the primary beneficiary. All significant intercompany transactions are eliminated in consolidation. Investments in entities that we do not control but have significant influence are accounted for under the equity method. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including estimates of fair value, probable losses and expenses, that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Unless otherwise noted, the information in Notes 1 through 11 refer only to our continued operations and do not include discussion of balances or activity of our discontinued operations. Effective with our first-quarter 2026 reporting, we realigned our internal management and reporting structure to reflect the evolution of our business model to focus on delivering converged advanced connectivity services across 5G and fiber to consumer and business customers. This new segment reporting structure also provides better visibility into the progress of exiting our copper-based Legacy operations. (See Notes 4 and 5) As a result of our change to this new segment reporting structure, we were required to reassess the assignment of goodwill and perform impairment testing of the previous and updated reporting units as of January 1, 2026; no impairment was recorded. The assignment of goodwill was based on the relative fair value of the reporting unit, which is deemed to be our principal operating segments or one level below. The goodwill from our previous Consumer Wireline and Mobility reporting units within the Communications segment was fully assigned to the reporting units comprising the Advanced Connectivity segment. No goodwill was assigned to the reporting unit comprising the Legacy segment as we expect sustained declines in Legacy service revenues driven by progress on our copper-based network decommissioning. Stock Repurchase Program In December 2024, the Board of Directors authorized the repurchase of up to $10,000 of AT&T common stock. We began buying back stock under this program in the second quarter of 2025. On January 27, 2026, the Board approved an authorization to repurchase an additional $10,000 of common stock. For the three months ended March 31, 2026, we repurchased approximately 88 million shares totaling $2,279 under the December 2024 authorization, excluding brokerage fees and the one percent excise tax imposed by the Inflation Reduction Act of 2022. To implement repurchase authorizations, we use open market repurchase programs, relying on Rule 10b5-1 of the Securities Exchange Act of 1934 where feasible.
