Fourth Quarter and Full Year 2022 Operational and Financial Highlights During the quarter and year ended December 31, 2022, NuVista: Record Achievements in Reserve Metrics NuVista is pleased to report the year end 2022 independent evaluation of our reserves by GLJ Ltd. ("GLJ") (the "GLJ Report"). With the infrastructure investment in our assets now largely behind us, our focus has shifted to building production volumes and maximizing the velocity at which invested capital is returned through exceptional half-cycle returns. The quality of our asset base is reflected in additional positive technical revisions to our production base and the highly efficient growth in reserves.
