| **Parex Resources Announces Update on Discussions with GeoPark Regarding a Potential Business Combination** | ![](tm2533192d1_ex99-1img001.jpg) |

---

**Calgary, Alberta, December 9, 2025** – 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.

The following summarizes key events that have taken place since October 29, 2025, the date Parex announced that it had previously submitted the September Proposal to the GeoPark board of directors, and that it had acquired an 11.8% ownership position in GeoPark:

· November 2, 2025: The Chief Executive Officer of GeoPark advises the Chief Executive Officer of Parex
that GeoPark is prepared to engage regarding a potential transaction between GeoPark and Parex.

· November 5, 2025: GeoPark publicly announces its intention to engage with Parex and that its Board
of Directors has formed a Special Committee of independent directors.

· November 4-13, 2025: Parex and GeoPark negotiate and execute a non-disclosure agreement ("NDA").

· November 14, 2025: GeoPark grants Parex access to a virtual data room and begins sharing select information.

· November 24, 2025: GeoPark publicly announces an off-cycle reserves update.

· November 24, 2025: Representatives of Parex and GeoPark hold a virtual meeting during which GeoPark
presents certain information regarding its assets.

· December 1, 2025: GeoPark publicly updates its guidance for 2026 to 2028.

· December 1, 2025: Representatives of Parex and GeoPark meet in person in Bogotá and share
their respective views of value. At the conclusion of the meeting, Parex advises GeoPark that, if the parties are unable to advance discussions
regarding a potential transaction within the parameters of the September Proposal, Parex will halt further discussions.

· December 5, 2025: The chair of the Special Committee of GeoPark and the chair of Parex directly establish
a communication channel.

· December 8, 2025: GeoPark reaffirms its prior position that it is not willing to negotiate a potential
transaction within the parameters of the September Proposal. The Chief Executive Officer of Parex advises the Chief Executive Officer
of GeoPark that Parex is halting further discussions.
