Terramont Infrastructure Partners, a middle-market North American infrastructure investment manager, has acquired a majority interest in Bull Moose Capital Ltd., Canada's largest natural gas compression solutions provider. The transaction, announced on October 2, 2025, marks the exit of TriWest Capital Partners from the Calgary-based company after a nine-year hold period.

Bull Moose has operated since 2004 in the Western Canadian natural gas compression rentals, sales, finance, and leasing market. The company maintains a fleet of over 290 compression and power generating assets, totaling over 160,000 horsepower, deployed across Western Canada and the Northern United States. The transaction value was not disclosed.

During TriWest's ownership, Bull Moose more than doubled its fleet and shifted toward higher-horsepower assets, becoming the largest natural gas compression operator in Western Canada. The company will continue under CEO Steve Kolber and Davis Aycock following the acquisition.

Stikeman Elliott LLP and K&L Gates LLP served as legal advisors to Terramont. Peters & Co. Limited acted as financial advisor to Bull Moose, with Burnet, Duckworth & Palmer LLP as legal counsel.
