RESULTS OF OPERATIONS

AT&T Inc. is referred to as “we,” “AT&T” or the “Company” throughout this document. AT&T products and services are provided or offered by subsidiaries and affiliates of AT&T Inc. under the AT&T brand and not by AT&T Inc., and the names of the particular subsidiaries and affiliates providing the services generally have been omitted. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications and technology industries. You should read this discussion in conjunction with the consolidated financial statements and accompanying notes (Notes). Percentage increases and decreases that are not considered meaningful are denoted with a dash.

On February 2, 2026, we closed our transaction with Lumen Technologies, Inc. (Lumen) and acquired substantially all of Lumen’s Mass Markets fiber business. 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 and are not included in our discussion of continuing operations. (See Notes 8 and 12)

Consolidated Results Our financial results from continuing operations are summarized in the discussions that follow. Additional analysis is discussed in our “Segment Results” section.

Operating revenues increased in the second quarter and for the first six months of 2026, reflecting higher Advanced Connectivity fiber and wireless revenues, with fiber revenues including the impact of acquiring Lumen’s mass markets fiber business. Operating revenues in Mexico were also higher due to favorable foreign exchange impacts. Offsetting the increases were lower Legacy revenues as we continue to work towards the decommissioning of our copper-based legacy network.

Operations and support expenses increased in the second quarter and for the first six months of 2026. The increase in the second quarter was primarily due to an asset abandonment charge associated with the reprioritization of our spectrum strategy, higher advertising expense, incremental customer costs related to our acquired mass markets fiber business and higher bad debt expenses driven by subscriber growth. These increases were partially offset by cost reductions from transformation initiatives, lower content licensing fees and gains on tower transactions.

The increase for the first six months was primarily due to higher wireless sales volumes, which drove higher equipment, selling and bad debt expenses. The increase was also due to higher network costs that included vendor credits in the prior year, and

incremental customer costs related to our acquired mass markets fiber business, which were partially offset by cost reductions from transformation initiatives, higher restructuring charges in the prior year and lower content licensing fees.

Depreciation and amortization expense decreased in the second quarter and for the first six months of 2026, primarily due to lower depreciation from fully depreciated legacy assets, partially offset by ongoing capital spending for strategic initiatives such as fiber and network upgrades.

Operating income increased in the second quarter and for the first six months of 2026. Our operating income margin in the second quarter increased from 21.1% in 2025 to 22.3% in 2026 and for the first six months increased from 19.9% in 2025 to 21.7% in 2026.

Interest expense increased in the second quarter and for the first six months of 2026, primarily due to higher debt balances and interest rates on long-term borrowings.

Equity in net income (loss) of affiliates decreased in the second quarter and for the first six months of 2026, primarily due

At June 30, 2026, we had no interest rate swaps.

We have fixed-to-fixed and floating-to-fixed cross-currency swaps on foreign currency-denominated debt instruments with a U.S. dollar notional value of $36,037 to hedge our exposure to changes in foreign currency exchange rates and interest rates. These derivatives have been designated as fair value or cash flow hedges with a net fair value of $(1,827) at June 30, 2026.

The registrant maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed by the registrant is recorded, processed, summarized, accumulated and communicated to its management, including its principal executive and principal financial officers, to allow timely decisions regarding required disclosure, and reported within the time periods specified in the SEC’s rules and forms. The Chief Executive Officer and Chief Financial Officer have performed an evaluation of the effectiveness of the design and operation of the registrant’s disclosure controls and procedures as of June 30, 2026. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the registrant’s disclosure controls and procedures were effective as of June 30, 2026.

There have not been any changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
