Suncor Energy (TSX:SU) (NYSE:SU) announced today that it has entered into a definitive agreement to sell its 48% interest in Terra Nova, 40% interest in White Rose and 38.6% interest in West White Rose offshore assets to Ithaca Energy plc (Ithaca) for $1.2 billion (US$860 million) of upfront cash and an additional contingent payment of up to $350 million (US$250 million), based on future oil prices.

In addition, Ithaca will assume investment commitments and all future liabilities associated with the assets, including a $500 million regulatory well compliance program starting in 2027 at Terra Nova and the total estimated abandonment and lease liabilities of $1.4 billion.

The transaction has an effective date of July 1, 2026 and is expected to close in early 2027, subject to customary closing conditions, regulatory approvals and partner consents. Suncor will retain its interests in Hebron and Hibernia.

"Our Investor Day commitments to grow normalized free funds flow and reduce WTI breakeven remain unchanged, reflecting the strength of our integrated asset base and confidence in our ability to deliver," added Rich Kruger.
