Copper Network Transition

AT&T INC. · 2026-10-21 · Importance 55 · Surprise 66 · No source text

AT&T expects Legacy service revenue to decline by more than 20% in 2026 and become immaterial by the end of 2029 as it decommissions its copper-based network. Legacy EBITDA is expected to turn negative after 2027 until the company substantially eliminates direct copper-network operating costs. Management’s strategy requires upgrading all customers in a geography before infrastructure decommissioning and removal of legacy fixed costs. Required approvals could delay the decommissioning program beyond 2029.
