The name traces to Alexander Graham Bell's 1885 company, which the government broke up in 1984; the modern entity descends from Southwestern Bell, which reassembled much of the system and adopted the AT&T name in 2005. Two large media bets, DirecTV in 2015 and Time Warner in 2018, were both unwound by 2022 at substantial cost. What remains is a wireless carrier and fiber broadband builder, with the Warner spinoff creating Warner Bros. Discovery. Headquarters are in Dallas.

AT&T equity questions
- How much T stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your T position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does AT&T grant ISOs, NSOs, or RSUs?
- Equity compensation at AT&T typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do AT&T RSUs use double-trigger vesting?
- No. AT&T restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
