GCI Advances $160M in $310M Deal to Buy Arctic Fiber Owner

GCI has agreed to buy Quintillion, owner of the roughly 1,700-mile fiber system that is the only wired connection between Alaska's Arctic coast and the rest of the state, for $310 million in cash, and has already advanced the seller $160 million while the sale awaits federal review.

Quintillion's network runs about 1,200 miles subsea from Nome to Prudhoe Bay and about 500 miles terrestrial to Fairbanks, and calls itself the first and only carrier to build subsea and terrestrial fiber in the U.S. Arctic. It has described itself as a wholesale operator selling capacity to all telecom providers, a position staked out publicly as early as 2016.

The purchase would put Alaska's largest telecommunications company in control of the route other carriers buy capacity on. That middle-mile infrastructure, the long-haul link between local networks and the wider internet, carries traffic for rural schools and clinics. The FCC must consent before the deal can close.

GCI Holdings, LLC signed the agreement April 21, 2026, disclosing it to the SEC two days later. The announcement was issued jointly by GCI and Grain Management, LLC; the seller is Q Gateway Ultimate Holdings, LLC.

Within 30 days of closing, GCI would reimburse up to $50 million more for Quintillion's spending on the Nome-to-Homer Express project, a statewide fiber ring that Quintillion says is funded partly by a federal middle-mile grant. Additional payments follow if revenues exceed thresholds in 2027, 2028 and 2030, payable in 2028, 2029 and 2031. GCI may settle the last one in stock.

GCI already advanced $160 million via a term loan at the Secured Overnight Financing Rate plus 8.50%, which counts against the purchase price if the deal closes or runs to April 21, 2031 if not. Some interest is paid in kind, so the balance grows.

Closing requires antitrust clearance, FCC consent, an operational Quintillion network, no prohibiting law, and completion of the terrestrial link between Quintillion's North Slope network and Utqiagvik. That link is Quintillion's Land Bridge Project, about 171 miles of overland fiber built after ice scouring severed the subsea cable in 2023 and 2025. Either side can walk after 18 months; if the deal fails on that deadline or a blocking order, GCI owes the seller $10 million.

This account is drawn from GCI's SEC filings, which are not only the buyer's description. The announcement quotes Quintillion president Mac McHale saying "GCI brings Alaska expertise, long-term commitment, and the operational scale needed to carry this network forward." GCI expects to close in the fourth quarter of 2026. The purchase agreement is public as Exhibit 2.1 and was not reviewed here. The filings say nothing about FCC docket status, or about rates, jobs and service commitments along the route.
