GCI will acquire 100% of Quintillion at a $310 million enterprise value, subject to working capital adjustments. The agreement includes up to $50 million in reimbursements for capital expenditures, a $160 million unsecured loan upon signing, and potential earnout payments in 2028, 2029 and 2031 tied to financial milestones.

The acquisition merges Quintillion’s 1,800+ miles of subsea and terrestrial fiber and 1,500 miles of planned expansion with GCI’s statewide network. The combined footprint will operate as a self-healing, ringed architecture to boost routing diversity, reduce outage durations and improve connectivity for remote Alaskan communities.

Post-close, GCI’s Alaska–based operations teams will centralize monitoring, maintenance and restoration, leveraging decades of regional expertise. Unified network planning and coordinated preventative maintenance are expected to optimize capital deployment while preserving existing customer agreements and grant-funded broadband projects.

The enhanced network is positioned to support national defense, public safety and Arctic communications by improving redundancy and restoration capabilities. This deal cements GCI Liberty’s status as Alaska’s largest provider and could drive long-term revenue growth and operational efficiency across its expanded infrastructure.
