NuVista Energy Ltd. Confirms 2025 Production Guidance

CALGARY, Alberta, Aug. 25, 2025 (GLOBE NEWSWIRE) -- NuVista Energy Ltd. (TSX:NVA, "NVA" or "NuVista") is pleased to confirm our annual average production guidance for 2025 of approximately 83,000 Boe/d ⁽¹⁾. Despite continued delays in commissioning the Pipestone Gas Plant ("Pipestone Plant"), we have been able to commence operations in the greater Wapiti area following the previously announced third-party plant maintenance outage earlier than forecast. As a result, if the Pipestone Plant is commissioned in September, our annual average production is forecast to be approximately 84,000 Boe/d and even if commissioning is delayed to the end of the year, our annual average production is forecast to be approximately 82,000 Boe/d.

Operational execution continues to progress well. We are ramping production back up above 90,000 Boe/d and finishing completions on our final pad for the year, and as a result we will have significant production behind pipe as the expanded facility capacity becomes available. Our strong balance sheet, opportunistic hedging, and less intensive second half 2025 capital plan will allow us to continue to make significant progress on our shareholder return strategy.

About NuVista
NuVista is an oil and natural gas company actively engaged in the exploration for, and the development and production of, oil and natural gas reserves in the province of Alberta. NuVista's primary focus is on the scalable and repeatable condensate-rich Montney formation in the Pipestone and Wapiti areas of the Alberta Deep Basin. This play has the potential to create significant shareholder value due to the high-value condensate volumes associated with the natural gas production and the large scope of this resource play. The common shares of NuVista trade on the TSX under the symbol NVA. Learn more at www.nuvistaenergy.com.

Advisories Regarding Oil and Gas Information
BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf: 1 Bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. As the value ratio between natural gas and crude oil based on the current prices of natural gas and crude oil is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

Basis of presentation
The reporting and measurement currency is the Canadian dollar. National Instrument 51-101 - "Standards of Disclosure for Oil and Gas Activities" includes condensate within the product type of natural gas liquids. NuVista has disclosed condensate values separate from natural gas liquids herein as NuVista believes it provides a more accurate description of NuVista's operations and results therefrom.
