AT&T Inc.

AT&T's 120.1 million wireless subscribers and 8.3+ million fiber customers generate monthly recurring service revenue, with postpaid phone churn of 0.87-0.98% in 2025 indicating strong retention. Service revenue grew consistently from FY2022 through FY2025, including through a period of intense competitive promotions, providing above-average forward visibility.

Mobility accounted for approximately 73% of Q4 2025 revenue ($24.4B of $33.5B), with Consumer Wireline and a structurally declining Business Wireline segment as secondary contributors. All three segments serve connectivity end markets, providing no genuine diversification across uncorrelated demand drivers.

The Communications segment generates approximately 97% of AT&T's segment operating revenues from the United States, with the Latin America segment (Mexico wireless, ~24.7 million subscribers) contributing roughly 3%. The company has no meaningful revenue presence outside North America.

AT&T plans annual capital investment of approximately $22 billion through 2027 to maintain and expand 5G and fiber networks, limiting incremental operating leverage. Wireless service revenue scales on existing spectrum and tower infrastructure, but fiber construction and 5G densification require sustained capital that constrains margin improvement in the near-to-medium term.

Wireless and fiber subscriptions are recurring and increasingly bundled together, with AT&T's convergence strategy driving 40% of fiber customers to subscribe to wireless service as of Q4 2025. The revenue mix includes a meaningful share of equipment sales and legacy wireline services that are either transactional or structurally declining, tempering overall quality.
