AT&T Inc.

AT&T Inc. is an American telecommunications and converged connectivity company that provides wireless, broadband, and legacy wireline services to consumers and businesses, generating $125.6 billion in revenue in fiscal 2025. The company serves 120 million wireless subscribers and passes over 37 million locations with fiber — the largest fiber footprint of any U.S. telecom operator — as it executes a multi-year turnaround strategy centered on pairing its wireless network with owner's-economics broadband.

This is a story about what happens after a century-old industrial champion exits two decades of disastrous capital allocation and tries to become something simpler. Between 2014 and 2021, AT&T spent roughly $170 billion acquiring DIRECTV and Time Warner, only to unwind both transactions at a fraction of the purchase price. The company that emerged in 2022 was a pure-play connectivity provider with a deeply damaged balance sheet, a declining legacy copper business, and a capital-intensive fiber buildout ahead of it. The turnaround under CEO John Stankey has been methodical: sell non-core assets, deleverage, invest heavily in fiber and 5G, and bet that customers who buy both wireless and broadband from AT&T will stay longer and spend more. The file turns on a single question: whether the convergence thesis can generate enough incremental cash flow to justify the $20-billion-plus annual capital investment before the weight of $174 billion in debt and a 5% dividend yield claim too much of the pie.

Three years into the strategy, the early returns are mixed but credible. Revenue is growing again, the fiber build is running ahead of plan, and the balance sheet has absorbed the February 2026 Lumen fiber acquisition. But postpaid phone churn is ticking up, the dividend still consumes nearly half of free cash flow, and the EchoStar spectrum transaction will push net leverage above 3.0x before it improves. This is not a business where the outcome is obvious — which is what makes it worth understanding.
