US-based GCI Completes $310 Million Acquisition of Quintillion Fiber Network

en.Wedoany.com Reported - On November 9, Alaska-based communications carrier GCI Holdings completed its acquisition of fiber infrastructure company Quintillion, obtaining all equity interests in its parent company Q Gateway Intermediate Holdings. The transaction had a previously agreed enterprise value of $310 million, with the actual consideration subject to transaction adjustment provisions. The acquisition brings Quintillion's existing submarine and terrestrial fiber network of more than 1,800 miles, as well as approximately 1,500 miles of planned expansion routes, into GCI's operating system, and the transaction has entered the closing and network integration stage.

The acquisition agreement was signed on April 21, 2026, and publicly announced on April 22. Under the original transaction terms, GCI acquired all equity interests in Quintillion at an enterprise value of $310 million, with additional compensation of up to $50 million for qualifying capital expenditures related to the Nome-to-Homer Express project. The agreement also includes earnout payment arrangements for 2028, 2029, and 2031, with specific additional payments contingent on the achievement of agreed financial metrics. GCI had previously provided Quintillion with a $160 million unsecured loan, which was settled as part of the acquisition price at closing in accordance with the agreement.

Quintillion's existing fiber network covers northern and western Alaska and consists of submarine cables and terrestrial fiber routes connecting Prudhoe Bay, Barrow, Wainwright, Point Hope, Kotzebue, and Nome. GCI will integrate these routes with its communications infrastructure covering the entire state of Alaska, conducting unified network planning, operational monitoring, maintenance, and fault recovery, and enhancing network redundancy through interconnection between different fiber routes.

GCI will initiate Quintillion network integration work following the completion of the transaction. Existing customer relationships, contractual obligations, and communications service arrangements will continue to be honored during the transition period, with relevant business services maintained without interruption. The company will also continue to advance Quintillion's ongoing fiber expansion projects and government grant-supported network projects, and will coordinate with customers, local communities, and project partners on subsequent construction and operational arrangements.

GCI is a wholly owned subsidiary of Liberty Capital Corporation and primarily provides fixed broadband, mobile communications, voice, and enterprise network services in Alaska. Following the completion of the acquisition, Quintillion's existing fiber assets will be managed uniformly by GCI, while the approximately 1,500 miles of planned expansion routes will continue to be built in accordance with the relevant project arrangements.
