From Exhibit 21 of the 10-K for 2025. Companies must list their significant subsidiaries there and may leave out smaller ones, so this is the company’s own list, not every entity it owns.

Read from AT&T’s annual reports (10-K for 2025, 10-K for 2024, 10-K for 2023, 10-K for 2022) and the financial data it files with the SEC, as of 2026-02-09. Every quotation is word for word from the filing linked beside it; how these pages are built and checked. The full record is in its company data sheet.
