Lumen Mass Markets Fiber Business
2026
$5.8B
Why
AT&T agreed in May 2025 to buy substantially all of Lumen's mass markets fiber business, including the Quantum Fiber operation, for $5.75 billion in cash, and closed the deal in February 2026. The purpose was to add fiber households outside AT&T's traditional wireline footprint.
Impact
The purchase added more than 1 million fiber subscribers across more than 4 million fiber locations in eleven states, including metros such as Denver, Seattle and Salt Lake City. Because it is a network-asset deal, the strategic fit is clearer than the company video and media purchases.
Outcome
AT&T expects the acquired subscribers to add roughly 100 basis points to 2026 advanced connectivity service revenue growth, and said the deal would not materially change 2026 EBITDA. Success depends on conversion, build economics and wireless bundling.
