Under the terms of the share-purchase agreement, Altius will acquire the remaining stake in Altius Renewable Royalties (ARR) currently held by Northampton Capital Partners. The deal, valued at 168 million dollars, grants Altius full control of the entity through which it previously held its indirect interest. Simultaneously, Northampton will acquire the membership interests held by affiliates of Apollo Global Management for approximately 390 million dollars, resulting in an equal 50-50 ownership split between Altius and Northampton.

Great Bay Renewables functions as a specialized financing platform, targeting royalties from utility-scale wind, solar, and energy storage projects across the United States. By securing this majority position, Altius integrates the platform more tightly into its operations. The transaction is slated for completion later this month.
