~~POSITIONED~~Bogota, Colombia – December 9, 2025 - GeoPark TOLimited ~~DOUBLE~~(“GeoPark” ~~EBITDA~~or ~~AND~~the ~~INCREASE~~“Company”) ~~PRODUCTION~~(NYSE: BYGPRK), ~~OVER~~a ~~60%~~leading ~~THROUGH~~independent ~~2028~~energy company with over 20 years of successful operations across Latin America, today commented on Parex Resources Inc.’s ("Parex") announcement that it has halted discussions with GeoPark regarding a potential transaction:

~~Bogota, Colombia~~· –GeoPark’s ~~December~~Board 1,and ~~2025~~management -team ~~GeoPark~~have ~~Limited~~always ~~(“GeoPark”~~been oropen ~~the~~to ~~“Company”)~~entering ~~(NYSE:~~into ~~GPRK),~~transactions athat ~~leading~~maximize ~~independent energy~~value ~~company~~for ~~with~~our ~~over~~shareholders. 20As ~~years~~such, ofwe ~~successful~~entered ~~operations~~into ~~across~~discussions ~~Latin~~with ~~America~~Parex in good faith, ~~today~~aiming ~~announced~~to ~~its~~negotiate ~~2026~~a ~~Work~~mutually ~~Program~~agreeable (transaction. From the ~~“Program”) and~~outset ~~2027-2028~~of ~~guidelines~~negotiations, ~~which~~we have ~~been~~communicated ~~approved~~our bybelief ~~the~~that ~~Company~~Parex’s ~~Board~~September 4, 2025, offer of ~~Directors~~$9.00 ~~(the~~per ~~“Board”)~~share undervalues GeoPark.

~~Execution~~· ~~Roadmap~~Over ~~Through~~six ~~2028:~~weeks ~~Scaling~~of aextensive ~~Two~~Special Committee and Board sessions and numerous meetings between our respective senior management teams, we provided Parex and its advisors access to substantial and comprehensive, non-~~Fold~~public ~~Strategy~~technical and financial information relevant to our ongoing operations and future upside potential – all of which is clearly incremental to the facts upon which Parex’s original offer was founded. Importantly, Parex’s $9.00 per share offer ascribed no value to GeoPark’s transformative Vaca Muerta acquisition which was announced on September 25, 2025. The Board has communicated that any credible or constructive engagement going forward would require a revised proposal beginning in the double-digits.

~~Protecting and~~This ~~Maximizing~~incremental ~~Core~~information ~~Production and Cash Generation in Colombia~~includes: The Company is focused on sustaining and improving the performance of its flagship Llanos 34 block and other key operated and non-operated assets. Following a strong 2025 and positive developments since GeoPark’s 2025 Investor Day, Colombian production has reached a positive inflection point earlier than expected. Production is set to grow, supported by disciplined development, base optimization, enhanced recovery techniques, and strong results from recent wells. These efforts are further underpinned by the recently certified 22% increase in the 2P Original Oil in Place (OOIP)1 in the Llanos 34 Block which confirms a significantly larger resource base and strengthens the long-term production and economic outlook of the asset. Colombia will continue to provide a solid foundation to generate sustainable free cash flow, balance sheet strength, and shareholder returns.

The company expects to drill 10-14 gross development, appraisal and injector wells, along with 20-22 workovers, plus infrastructure and facilities.Advisors

· Vaca Muerta - 5 wells, $80-100 million CAPEX:

- Loma Jarillosa Este and Puesto Silva Oeste: Focus on accelerating activity by finalizing the drilling, fracking and putting on production of 1 pad of 5 wells, installing rod pumps in 3 wells, upgrading facilities in the Loma Jarillosa Este Block, and advancing permitting for the Puesto Silva Oeste Block and shared facilities.

Strengthening Capital Discipline and Cost Efficiency

The Program is anchored on capital discipline, financial resilience, and enduring value creation. Under a $60-70/bbl Brent base scenario, the Company expects to generate $220-300 million in Adjusted EBITDA3 in 2026. By 2028, Adjusted EBITDA is forecasted to grow to $490-520 million, equivalent to approximately 1.3 times total capital expenditures, and resulting in a projected ROACE4 of 25-30%.

The program will be primarily funded through internal cash generation and available debt facilities. At base case prices, year-end 2026 cash is expected to range between $130 and 140 million, with a net debt to EBITDA leverage ratio of 1.9-2.1x. Leverage is projected to decline below 1.5x by 2028 as cash flow increases and capital investments normalize.

The Company also remains focused on cost efficiency across its portfolio. Lifting costs are targeted to remain below $15/bbl in 2026, trending toward ~$12/bbl by 2028. General and administrative (G&A)5 expenses are expected to remain around $4/bbl during 2026 and reach approximately $3/bbl by 2028.

GeoPark’s hedging strategy continues to play a central role in protecting cash flows and ensuring competitive price realizations. As of November 26, 2025, the Company had hedged approximately 56% of its 2026 estimated production6. This figure reflects an upward revision to projected volumes since the Company’s 2025 Investor Day. GeoPark intends to maintain hedging coverage in the range of 50-70% of forecasted production, in line with its risk management framework.

Shareholder Returns: Maximizing Shareholder Value Through Growth

Following the completion of the Vaca Muerta acquisition and considering its projected capital needs, the Board approved a revised dividend program consisting of approximately $6 million in distributions over four quarters. This equates to $1.5 million per quarter (or $0.03 per share), beginning with the 3Q2025 results payout and ending with the 2Q2026 results payout.

GeoPark remains firmly focused on maximizing shareholder value. Adjusted EBITDA is expected to more than double by 2028, driving a larger enterprise value supported by increased cash flow, lower leverage, and a broader, more diversified asset base. Furthermore, the Board will reassess capital allocation priorities once the Company returns to positive free cash flow after its peak investment phase, consistent with GeoPark’s disciplined, returns-based capital allocation framework.

Felipe Bayon, Chief Executive Officer of GeoPark, said: “Our 2026 Work Program and execution roadmap is designed to maximize shareholder value and deliver enduring results. Our strategy is clear: strengthen and maximize our core platform in Colombia and build a new engine of long-term growth in Argentina. Building on the reset accomplished in 2025, the 2026 Work Program balances near-term cash generation with the upfront investments required to transform the scale of our business and enhance future cash flow resilience. This is a disciplined, returns-focused plan that reflects the quality of our assets and the strength of our balance sheet, and the distinctive operating capabilities of our team across the region.”

3 Assuming a $2-3 Vasconia/Brent differential and a $2-3 Medanito/Brent differential.

4 ROACE: Last twelve-month operating profit divided by average capital employed. Capital employed is calculated as total assets minus current liabilities and adjusted for excess cash. Excess cash corresponds to the portion of cash and cash equivalents that exceeds the amount required to cover current liabilities with current assets.

5 G&A includes administrative expenses and geological and geophysical expenses, excluding certain non-cash items, such as accrual of share-based payment, geological and geophysical expenses allocated to capitalized projects and IFRS 16 adjustment, which are excluded from the Adjusted EBITDA calculation; calculated over produced barrel.

6 Net average production after economic rights and royalties. GeoPark monitors market conditions on a continuous basis and may enter into additional commodity risk management contracts to secure minimum oil prices for its 2026 production and beyond.
