We view monetization as a continuous process, and this transaction positions the asset for its next phase of growth with an operator uniquely equipped to enhance its reach and reliability."

The combination of Quintillion's network with GCI's statewide operations is expected to enhance reliability, resiliency, and reach of critical communications infrastructure across Alaska, including in support of public safety and national security applications. The transaction is subject to customary closing conditions.
