AT&T T · USD

AT&T, formerly known as SBC Communications Inc. (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.

Corporate support costs, including administrative support costs borne by AT&T where business units do not influence decision making, and results from business no longer integral to our operations are reported as Corporate and Other, which reconciles our segment results to consolidated operating income and income before income taxes.

We are a leader in providing connectivity services through our market focus areas of 5G and fiber. Fiber underpins the connectivity we deliver, both wired and wireless. Building on that fiber foundation is our solid spectrum portfolio, strengthened through Federal Communications Commission (FCC) auctions, other spectrum acquisitions and 5G deployment. We believe our fixed wireline and mobile approach will differentiate our services and provide us with additional convergence growth opportunities in the future as bandwidth demands continue to grow. We will continue to demonstrate our commitment to ensure management attention is sharply focused on growth areas and operational efficiencies.
