UP Fiber has acquired AT&T's wireline assets across Michigan’s Upper Peninsula and Mackinaw City.

Financial terms of the deal, which was completed last week, were not revealed.

As part of the deal, UP Fiber acquires more than 9,000 miles (14,484 km) of network infrastructure, along with related facilities, spanning 40 central offices.

“This is an important moment for the Upper Peninsula,” said Dan Miller, chief executive officer, UP Fiber. “The need for reliable voice and broadband service continues to grow as more people work from home and families find creative ways to stay in touch. We are excited to make the investments needed to improve service, expand capabilities, and strengthen access across the Upper Peninsula.”

Founded in 1908, initially as Upper Peninsula Telephone Company (UPTC), UP Fiber is owned by Michigan Broadband, a subsidiary of MachTen Inc.

UP Fiber noted that it will invest significant capital over time in modernizing and strengthening its network.

The company said it will partner with Michigan Broadband, a subsidiary of MachTen, Inc., to support a broad range of communications services, including dependable home phone, Internet access, and video. This partnership will look to expand these services to more than 200,000 locations.

AT&T will continue to provide operational support for certain functions as part of the transition process, notes UP Fiber. During this time, the US carrier will continue to provide billing and technical support for existing customers.
