CALGARY, Alberta, Nov. 04, 2025 (GLOBE NEWSWIRE) -- NuVista Energy Ltd. (TSX:NVA) ("NuVista") is pleased to announce that it has entered into a definitive arrangement agreement (the "Agreement") with Ovintiv Inc. ("Ovintiv") (TSX:OVV, NYSE:OVV) and Ovintiv Canada ULC ("Ovintiv Canada") pursuant to which Ovintiv Canada has agreed to acquire all of the issued and outstanding common shares of NuVista ("NuVista Shares") (the "Transaction") not already owned by Ovintiv or its affiliates, in a cash and share transaction that values NuVista at approximately $3.8 billion, including the assumption of NuVista's net debt.

Under the terms of the Agreement, holders of NuVista Shares other than Ovintiv or its affiliates ("NuVista Shareholders") will have the option to elect to receive for each NuVista Share: (i) $18.00 in cash; (ii) 0.344 Ovintiv common shares (each whole share, an "Ovintiv Share"); or (iii) a combination of cash and Ovintiv shares, subject to pro-ration based on a maximum amount of cash and a maximum amount of Ovintiv Shares set out in the Agreement (the "Purchase Price"). The maximum amount of cash and maximum amount of Ovintiv Shares each represent 50% of the aggregate consideration payable to NuVista Shareholders.

The proposed Transaction is to be completed by way of a plan of arrangement ("Arrangement") under the Business Corporations Act (Alberta) (the "ABCA") and, subject to satisfaction of conditions typical for a transaction of this nature, is expected to close in the first quarter of 2026.

"We are very excited about this strategic transaction with Ovintiv and its unique opportunity for synergy realization that will maximize the value of NuVista's top-tier Montney acreage. I am extremely proud of the NuVista team who have contributed to the successful delineation and growth of our asset base that positioned us to deliver this outcome for our shareholders," said Mike Lawford, President and CEO of NuVista. "Our team has been critically focused on generating best-in-class returns for our shareholders and this transaction will provide exposure to a complementary portfolio of assets in Ovintiv that share the same quality and longevity to ours."

Note:

(1) Premium to NuVista's unaffected 20 day volume-weighted Nuvista Share price as of September 19, 2025, the last trading day preceding Ovintiv or its affiliates' purchase of 18.5 million NuVista Shares, which represents 9.6% of the issued and outstanding NuVista Shares.
