Altius Minerals Increases Great Bay Renewables Ownership to 50% and Secures Larger Credit Facility

Altius Minerals Corporation (TSX: ALS) has closed a deal to nearly double its stake in Great Bay Renewables (GBR), a U.S. renewable energy royalty platform, from 29% to 50%. The move cost Altius approximately US$168 million, according to National Post.
The deal was part of a three-way transaction. Apollo-managed funds sold their GBR membership interests — split between Northampton Capital Partners for roughly US$390 million and Altius for US$168 million. Northampton's effective interest in GBR dropped from 22% to 49% as a result, Montreal Gazette reported.
Apollo affiliates held a significant stake in GBR before this deal. They sold their entire membership interest in a single transaction, splitting proceeds between two buyers. Altius paid US$168 million to jump from a minority 29% position to an equal 50% co-ownership. Northampton, the other buyer, absorbed the rest of Apollo's stake, according to Sault Star.
The result is a clean two-party ownership split. Altius holds 50% and Northampton holds 49%. GBR operates as a renewable energy royalty company, meaning it collects payments from wind and solar projects without directly owning or operating them — a low-overhead, long-term income model, Brantford Expositor noted.
Alongside the GBR deal, Altius announced a major upgrade to its credit facility. The borrowing limit increased from C$225 million to C$350 million — a jump of C$125 million. The maturity date was also pushed out, moving from August 2028 to July 2030, The Observer reported.
Bank of Nova Scotia and Toronto-Dominion Bank led the facility. National Bank of Canada, ATB Financial, Desjardins Financial Security Life Assurance Company, and Export Development Canada also participated. The funds can be used for royalty deals, streaming acquisitions, and other qualifying investments. Interest rates are variable, according to Stratford Beacon Herald.
GBR is a royalty company focused on U.S. renewable energy projects. It earns revenue from wind and solar developers who pay royalties in exchange for land-use rights or other agreements. This model gives GBR — and its owners like Altius — steady, long-term cash flows without taking on construction or operating risk, Fort McMurray Today explained.
For Altius, the increased stake is a meaningful strategic shift. The company is best known as a mining royalty firm, but GBR gives it growing exposure to clean energy income. Moving from 29% to 50% ownership gives Altius far more influence over GBR's direction and a larger share of its future royalty income, Chatham Daily News reported.
The expanded C$350 million credit facility gives Altius significantly more firepower for future deals. Royalty companies grow by acquiring new royalty streams, and access to cheap credit is key to moving fast when opportunities arise. The two-year extension on the loan's maturity also reduces near-term refinancing pressure, according to Clinton News Record.
Together, the GBR stake increase and the credit upgrade signal that Altius is pushing deeper into renewable energy while keeping its mining royalty base intact. The company now controls half of one of North America's few dedicated renewable royalty platforms — a rare position in a fast-growing sector, The Crag and Canyon noted.
