Cenovus Energy announces it has entered into a definitive arrangement agreement to acquire Athabasca Oil Corporation in a cash-and-stock transaction valued at an implied enterprise value of $5.7 billion. Athabasca shareholders receive $12.00 per share under the deal terms described by the companies.

The agreement is framed as a move to expand Cenovus’s presence in Alberta’s oil sands. BNN Bloomberg and the Financial Post both describe the transaction as strengthening Cenovus’s position among Canada’s large oil sands producers. Investing.com reports Cenovus shares fall following the announcement, reflecting market reaction.

Athabasca’s own disclosure, as reported by BNN Bloomberg, adds details on the structure and timing: the transaction implies an equity value of about $5.8 billion and is expected to close in December 2026, subject to customary approvals. The Globe and Mail notes the deal comes less than a year after Cenovus acquired MEG Energy, placing the Athabasca purchase in the context of Cenovus’s recent growth strategy.
