AT&T is scheduled to report Q3 2026 results on October 21, with Wall Street consensus revenue estimates clustered around $31.65–$31.7 billion, implying roughly 3% year-over-year growth from the $30.71 billion posted in Q3 2025. Traders are focused on whether postpaid phone net additions, fiber subscriber growth, and advanced connectivity revenue can sustain the sequential acceleration seen in Q2, when service revenue rose 2.7% year-over-year amid network modernization and convergence initiatives. Management has reiterated full-year 2026 service revenue guidance in the low single digits, alongside 3–4% adjusted EBITDA growth, providing a benchmark for the quarter. Recent corporate moves, including a new fiber joint venture and spectrum-related transactions, add limited near-term revenue visibility but underscore capital allocation priorities ahead of the print.
