Cenovus Energy Inc. announced Monday that it has entered into a definitive arrangement agreement to acquire Athabasca Oil Corporation in a cash and stock transaction with an implied enterprise value of USD 5.7 billion.

Under the arrangement agreement, Cenovus will acquire all issued and outstanding common shares of Athabasca at a price of USD 12.00 per share, payable in cash and Cenovus common shares.

Deal terms

Each Athabasca shareholder, other than dissenting shareholders, will have the option to elect to receive, for each Athabasca common share held, USD 12.00 in cash, 0.264 of a Cenovus common share, or a specified proportion of cash and shares. Shareholders who do not make a valid election will be deemed to have elected to receive cash.

All elections will be subject to pro-ration based on a maximum of USD 4.3 billion in cash, equivalent to 75 percent of the total consideration, and a maximum of 44.4 million Cenovus common shares, equivalent to 35 percent of the total consideration. The aggregate consideration will therefore comprise between 65 and 75 percent cash and between 25 and 35 percent Cenovus shares, depending on elections made and deemed to be made by Athabasca shareholders. Depending on a particular shareholder's election and pro-ration, a shareholder may ultimately receive entirely cash, entirely Cenovus shares, or a combination of both.

The transaction has been unanimously approved by the boards of directors of both companies. Athabasca's directors and executive officers have entered into voting and support agreements with Cenovus, agreeing to vote the approximately 2.2 percent of Athabasca's issued and outstanding common shares they beneficially own or control in favour of the transaction.

Cenovus expects the acquisition to close in December 2026, subject to customary closing conditions including regulatory approvals and shareholder approval. The transaction is not subject to any financing contingency.

Strategic fit with core oil sands business

Cenovus said the acquisition adds approximately 45 thousand barrels of oil equivalent per day, including thermal production proximal to the company's Christina Lake, May River and Thornbury assets, expanding its position in a core resource fairway.

The company described the acquired assets as a high-quality, long-life resource with over 75 years of proved plus probable reserves life, based on the estimated 2026 production exit rate, including oil sands assets at Leismer and Corner. Cenovus said the assets provide significant growth potential and a pathway to accelerate thermal production to 115 thousand barrels per day by 2032.

Cenovus intends to apply its SAGD operating expertise to the acquired assets, and said that application of its proven SAGD operating model is expected to enhance reservoir performance, reduce steam-to-oil ratios, and accelerate resource recovery.

The company pointed to a differentiated project execution track record, including the profitable completion of more than 30 successful oil sands phase expansions to date, which it said uniquely positions it to optimize the value of the acquired SAGD assets.

"This transaction strengthens our position in one of the world's premier oil-producing regions and is a natural extension of our oil sands strategy," said Jon McKenzie, Cenovus President and Chief Executive Officer.

"Athabasca's high-quality, long-life assets fit well with our portfolio and provide a clear opportunity to apply our scale and operating expertise to improve performance, grow production, and create long-term shareholder value."

Duvernay platform consolidation

The deal also consolidates ownership of Duvernay Energy Corporation, a high-quality, oil-weighted position in the Kaybob Duvernay, which Cenovus said comes with the option to accelerate development and grow production to a sustainable 20 thousand barrels of oil equivalent per day.

Synergies and funding

Cenovus expects to realize approximately USD 85 million per year of corporate and commercial synergies, with the majority captured in the first full year following closing of the transaction.

The cash portion of the consideration will be funded with cash on hand and certain short-term borrowings. Cenovus's financial framework and its net debt target of USD 4 billion are to remain unchanged.

Cenovus's net debt at the end of the third quarter was approximately USD 3.0 billion. Including the cash component of the transaction, year-end 2026 pro forma net debt is expected to be between USD 5.0 billion and USD 5.5 billion at strip pricing, representing less than 0.5 times adjusted funds flow.

That figure assumes the maximum aggregate cash consideration of 75 percent, or USD 4.3 billion, and includes estimated transaction costs incurred upon closing, forecasted at forward strip pricing as of September 30, 2026. The company noted that pro forma net debt may differ based on Athabasca shareholder elections and pro-ration.

CIBC Capital Markets is acting as the exclusive financial advisor to Cenovus, and McCarthy Tétrault LLP is acting as legal advisor to Cenovus. Cenovus hosted a conference call on October 5, 2026, starting at 7 a.m. MT (9 a.m. ET), with analysts required to register in advance to receive a unique PIN to access the call via telephone.
