(SBC), was formed as one of several regional holding companies created to hold AT&T Corp.’s (ATTC) local telephone companies. On January 1, 1984, we were spun-off from ATTC pursuant to an anti-trust consent decree, becoming an independent publicly traded telecommunications services provider. Following our formation, we expanded our communications footprint and operations, most significantly: • Our subsidiaries merged with incumbent local exchange carriers (ILEC) Pacific Telesis Group in 1997 and Ameritech Corporation in 1999. • In 2005, we merged one of our subsidiaries with ATTC, creating one of the world’s leading telecommunications providers. In connection with the merger, we changed the name of our company from “SBC Communications Inc.” to “AT&T Inc.” • In 2006, we acquired ILEC BellSouth Corporation (BellSouth), which included BellSouth’s 40% economic interest in AT&T Mobility LLC (AT&T Mobility), formerly Cingular Wireless LLC, resulting in 100% ownership of AT&T Mobility. • In 2014, we completed the acquisition of wireless provider Leap Wireless International, Inc. • In 2015, we acquired wireless properties in Mexico and acquired DIRECTV, a leading provider of digital television entertainment services in both the United States (included in our former Video business) and Latin America (referred to as Vrio, which was sold in November 2021). • In July 2021, we closed our transaction with TPG Capital (TPG) to form a new company named DIRECTV Entertainment Holdings, LLC (DIRECTV). With the close of the transaction (DIRECTV Transaction), we separated our Video business, comprised of our U.S. video operations, and began accounting for our investment in DIRECTV under the equity method. In July 2025, we sold our remaining interest in DIRECTV to TPG. General We are a leading provider of telecommunications and technology services globally. The services and products that we offer vary by market and utilize various technology platforms in a range of geographies. Our
