AT&T Q3 Beat on Postpaid Phone Growth Drives 2026 EPS Outlook Upgrade

• AT&T (T) beat Q3 2026 EPS and raised full-year 2026 EPS outlook on strong postpaid net additions and improving FCF
• Fibre broadband subscriber additions continue to drive ARPU expansion, offsetting legacy wireline revenue erosion
• AT&T turnaround thesis tracking ahead of schedule set at 2024 investor day

AT&T's Q3 beat and 2026 EPS upgrade represent a meaningful milestone in one of the most watched corporate turnarounds in US communications. After years of acquisitions, debt accumulation and strategic misfires, AT&T has returned to basics — postpaid wireless and fibre broadband — and is seeing the financial benefits. Q3 postpaid phone net additions beating expectations indicates AT&T is regaining subscriber momentum relative to T-Mobile and Verizon, reversing a multi-year share loss trend.

The fibre broadband thesis is the most important long-term value driver. AT&T has committed to passing 30+ million US homes with fibre by 2025-2026, and each fibre subscriber generates significantly higher ARPU than a copper DSL subscriber. More importantly, fibre subscribers churn at roughly half the rate of cable modem customers, creating a durable revenue base investors can value on a more stable cash flow basis.

The critical risk variable is AT&T's debt level. The company still carries substantial debt from its DirecTV and WarnerMedia era, and a higher-for-longer rate environment extends the duration cost of refinancing. Management's FCF guidance upgrade matters because AT&T needs free cash flow to fund network investment, pay its dividend and reduce debt simultaneously. Any negative revision to FCF guidance would reopen the dividend sustainability debate.
