NUVISTA ENERGY LTD. ADVISES OF WILDFIRE IMPACT IN GRANDE PRAIRIE OPERATIONS

Due to the continuing wildfire situation in the Grande Prairie region, NuVista Energy Ltd. has temporarily shut in and depressured all operations proximal to the continuing fires. This is a precautionary measure to ensure the protection of the company's people, the public and its assets is foremost. The shut-ins began partially on May 5, 2023, and were then broadened by the shut-in of third party infrastructure which serves NuVista's production. Personnel are monitoring from safe locations. The temporary production impact is approximately 40,000 boe/d, and NuVista stands ready to restart operations as soon as the risk is diminished. The company is not aware of damage to any company or third party assets and infrastructure. The company thanks its field staff for their swift and professional response to this situation, and NuVista's thoughts are with any impacted community members.

About NuVista Energy Ltd.

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, 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.
