AT&T Stock's Margin Hit A Multi-Year Best As Its Copper Network Winds Down
AT&T (T) reported a consolidated adjusted EBITDA margin increase of 110 basis points to 39.1% in Q2 2026, driven by revenue growth and cost savings.

The company aims to discontinue legacy services in over 30% of wire centers by late 2026, targeting $4 billion in annual cost savings by 2028. Fiber ARPU fell 1.3% year-over-year, but AT&T added 147,000 consumer postpaid wireless accounts, its best in over three years.
