(“Pluspetrol”) of a 100% operated working interest (“WI”) in the Loma Jarillosa Este and Puesto Silva Oeste blocks, located in the black oil window of the Vaca Muerta formation in Neuquén Province, Argentina.

The Government of Neuquén Province has issued two decrees—DECTO-2025-1226 for the Loma Jarillosa Este Block and DECTO-2025-1270 for the Puesto Silva Oeste Block—and with the issuance of such decrees, all required governmental and regulatory approvals with respect to the acquisition have now been obtained.

Following the issuance of the above-mentioned decrees, GeoPark and Pluspetrol have executed public deeds formalizing the transfer of the concessions. As part of the closing, GeoPark has disbursed the remaining balance of the purchase price¹, for a total consideration of $115 million².

The prompt completion of this transaction highlights the strong collaboration between GeoPark, Pluspetrol, GyP, and the Government of Neuquén Province, as well as GeoPark’s long-term commitment to Argentina, disciplined investment, operational excellence, and close partnership with local stakeholders.
