(SOUTHERN COLORADO) — AT&T announced it has reached a deal with Lumen, which operates CenturyLink and Quantum Fiber in 11 states, including Colorado.

According to AT&T, the company reached an agreement to acquire substantially all of Lumen’s Mass Markets fiber business for $5.75 billion, subject to purchase price adjustments in an all-cash transaction. The acquisition will include last-mile fiber assets and associated network elements in central offices that enable fiber services.

“We’re leading the race to connect more Americans with fiber, the best broadband connectivity technology available,” said John Stankey, Chairman and CEO, AT&T. “This deal with Lumen represents a significant investment in U.S. connectivity infrastructure that will create jobs and spur economic activity in numerous regions and major metro areas across 11 states. As we advance our fiber build, we’ll serve more communities with world-class connectivity and expect to roughly double where AT&T Fiber is available by the end of 2030.”

The deal impacts CenturyLink and Quantum Fiber customers, including those in Colorado Springs and Pueblo. AT&T said that over time, customers will transition to AT&T Fiber. The service will be backed by AT&T Guarantee and offer multi-gig speeds.

AT&T also hopes the deal will enable expansion of AT&T fiber further in areas that already have fiber and into major metro areas like Denver, Las Vegas, Minneapolis-St. Paul, Orlando, Phoenix, Portland, Salt Lake City, and Seattle.

The deal is expected to close in the first half of 2026, and AT&T said it will extend its fiber network with plans to reach about 60 million fiber hookups by the end of 2030.
