FOR IMMEDIATE DISTRIBUTION

GEOPARK PROVIDES UPDATE ON TRANSACTION IN VACA MUERTA, ARGENTINA

Bogota, Colombia – May 14, 2025 - GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), a leading independent energy company with over 20 years of successful operations across Latin America, announces today that Phoenix Global Resources (“Phoenix”), the counterparty to the transaction through which GeoPark agreed to acquire a non-operated working interest in four unconventional blocks in Vaca Muerta (Argentina), has decided to withdraw from the agreement. As a result, the acquisition will not be completed by GeoPark.

As previously referenced during GeoPark’s 1Q2025 Results Conference Call, and in accordance with the terms of the FarmOut Agreement, either party had the right to withdraw from the transaction following the contractually defined “Outside Date” of May 13, 2025.

Notwithstanding this development, GeoPark remains firmly committed to its long-term North Star strategy—anchored in profitable, dependable, and sustainable growth through the development of Big assets, in Big plays, within Big basins. This strategy is underpinned by a solid cash balance, currently at $330 million, conservative net leverage ratio below 1.0x, a robust hedging program that now covers approximately 87% of 2025 volumes, and a disciplined capital allocation framework—which provides the Company with the flexibility to pursue other strategic opportunities and continue advancing the following core priorities:

Strengthening the Core Business - The Company remains focused on executing its 2025 organic work program, prioritizing high-return projects to maximize returns and cash generation from its core portfolio

Pursuing Value-Accretive Growth - Inorganic growth opportunities within GeoPark’s defined geographies of interest continue to be actively evaluated, aiming to complement the existing portfolio and support long-term value creation

Strategic Optionality - GeoPark continues to evaluate a range of value-enhancing alternatives, including dividends, share buybacks, and potential debt reduction, depending on market conditions

GeoPark appreciates the continued trust and support of its shareholders and stakeholders. The Company remains committed to maintaining open communication while pursuing disciplined growth opportunities that generate long-term value for all its stakeholders.
