Altius Minerals Boosts Stake in Great Bay Renewables to 50% in $390 Million Partnership

Altius Minerals Corporation (TSX: ALS) has agreed to spend roughly US$390 million to double its stake in Great Bay Renewables, a renewable energy royalty company. The deal will lift Altius's ownership in Great Bay Renewables Holdings from 29% to 50%, according to Seaforth Huron Expositor.
The agreement involves buying shares from Northampton Capital Partners and funds tied to Apollo (NYSE: APO). Northampton will also sell its stake in Altius Renewable Royalties Corp. (ARR) to Altius. The deal is expected to close in late July.
The US$390 million total is split into two parts. Altius will pay US$168 million specifically for Northampton's interest in ARR, its renewable royalty subsidiary. Fort McMurray Today reports that Altius plans to fund that portion using existing cash and liquidity already on hand.
The remainder covers Great Bay Renewables Holdings shares being sold by Northampton and Apollo-affiliated funds. Altius is effectively consolidating control over its renewables platform in a single large transaction rather than through a series of smaller moves.
Great Bay Renewables is a royalty company focused on clean energy projects. Royalty companies provide upfront cash to project developers. In return, they collect a share of revenue over time. This model gives Altius steady, long-term income without directly building or operating wind and solar farms.
Moving from 29% to 50% ownership is a major shift. At 50%, Altius gains equal footing with its partners. It also gains more influence over how Great Bay Renewables grows and deploys capital into new clean energy projects, according to Hanna Herald.
Northampton Capital Partners is exiting both its GBR and ARR positions in this deal. Apollo-affiliated funds are also selling their GBR shares. The move suggests both parties are cashing out of a stake that has likely grown in value as renewable energy assets have attracted strong investor interest globally.
For Apollo, one of the world's largest alternative asset managers, the sale fits a broader pattern of rotating capital out of maturing investments. Altius, by contrast, is doubling down on renewables as a core part of its long-term royalty strategy.
The transaction is subject to what the company calls "customary terms and conditions." These typically include regulatory approvals and confirmation that no major issues arise before closing. Altius expects the deal to wrap up in late July, according to Seaforth Huron Expositor.
Altius cautions that the deal involves forward-looking assumptions. Risks include possible failure to meet closing conditions or unexpected delays. If any condition is not satisfied, the transaction could be delayed or fall through entirely.
