WASHINGTON, April 22, 2026 /PRNewswire/ — Grain Management, LLC (“Grain”), a leading private investment firm focused on digital infrastructure and communications, today announced that it has entered into a definitive agreement to sell Quintillion, a leading provider of subsea and terrestrial fiber infrastructure in Alaska, to GCI Holdings, LLC (“GCI”).
Quintillion operates a strategically important fiber network spanning some of the most remote and challenging environments in North America. Under Grain’s ownership, the company advanced the development of resilient, high-capacity infrastructure designed to support mission-critical connectivity across Alaska, serving carriers, government, healthcare, and enterprise customers.
“Grain has been a strong and supportive partner as we built and expanded Quintillion’s network in one of the most demanding operating environments in the world,” said Mac McHale, President of Quintillion. “Their long-term approach and sector expertise enabled us to strengthen our platform and deliver critical connectivity across Alaska. We’re excited about the opportunity to continue that momentum with GCI.”
“We are proud of the progress Quintillion has made in building and scaling a highly differentiated fiber platform in Alaska,” said Chad Crank, Managing Director at Grain Management. “This outcome reflects our disciplined approach to value creation: underwriting for resilience, partnering with strong management teams, and strategically scaling infrastructure in markets where deep sector expertise creates an advantage. 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.
