Parex Ends GeoPark Takeover Talks, Says $9 Per Share Offer Won't Change

Parex Resources Inc. ("Parex" or the "Company") (TSX:PXT) today announced that it has halted discussions with GeoPark Limited ("GeoPark") (NYSE:GPRK) regarding the acquisition of GeoPark by Parex.

Based on Parex's review of information provided by GeoPark since November 14, 2025, as well as virtual and in-person discussions with GeoPark management, Parex has determined that there is no basis to increase its view on the value of GeoPark common shares relative to the proposal to acquire all GeoPark shares for US$9.00 per share in cash, which Parex submitted to the GeoPark board of directors on September 4, 2025 (the "September Proposal"). Following its engagement with Geopark over the past month, Parex concluded, given the gap in perceived value, that further discussions were unlikely to lead to any agreement with respect to a transaction between GeoPark and Parex as outlined in the September Proposal and has determined to halt discussions with GeoPark.
