Investment Reflects Confidence in Geopark’s Assets, Team and Vision

Further Enhances Financial Flexibility and Brings Additional Value Creation Expertise to the Company

GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), a leading independent energy company with over 20 years of successful operations across Latin America, today announced a strategic private investment in public equity (PIPE) transaction with Colden Investments S.A. (“Colden”), an affiliate of Jaime Gilinski, who leads one of Latin America’s most diversified global investment groups (“Grupo Gilinski”). The investment was led by Jaime and Gabriel Gilinski.

Under the agreement, Colden invested approximately $107 million to acquire 12,876,053 newly issued common shares of GeoPark at a price of $8.31 per share¹. The closing of the transaction results in Colden holding approximately 20% of GeoPark’s outstanding common shares² and becoming the largest shareholder of the Company.

Shared Vision to Build a Leading Independent Energy Platform in Latin America

The investment by Colden reflects alignment with and endorsement of GeoPark’s strategic ambition: to become the leading independent oil and gas platform in Latin America through disciplined organic and inorganic growth, building on the platform and reputation created by GeoPark over 23 years of operation. The investment also reflects confidence in the value generation potential of the Latin American energy space, including Colombia consolidation, Vaca Muerta scale-up and potential access in Venezuela, while preserving flexibility to pursue other emerging opportunities. The outcomes sought are superior shareholder returns, supported by scale, resilience, technical excellence, capital discipline and culture, underpinned by non-negotiable standards on safety, integrity, compliance, environmental stewardship, communities, and regulatory responsibility.

Following the decisive actions taken by GeoPark’s Board and leadership over the past year to increase the Company’s scale, enhance its growth profile and build a more resilient and diversified platform, GeoPark received interest from investors evaluating meaningful ownership positions.

Grupo Gilinski has followed GeoPark’s strategic evolution over time and approached the Company expressing conviction in GeoPark’s long-term ambition and regional growth potential. The Board determined that the Gilinskis demonstrated strong alignment with GeoPark’s growth roadmap and governance principles in connection with their investment, establishing Grupo Gilinski as the right long-term partner for the Company’s next phase, with capabilities and expertise that extend beyond the capital provided through this PIPE.

Strategic Rationale of Grupo Gilinski

Grupo Gilinski sees GeoPark as a well-positioned regional platform with an established operational footprint in Colombia and a growing presence in Argentina. The Company’s track record of disciplined execution, technical expertise and capital allocation provides a strong foundation for continued consolidation and organic development in its core markets.

In Colombia, Grupo Gilinski recognizes opportunities to further strengthen GeoPark’s position through bolt-on acquisitions, increased working interests in existing blocks and continued development of underexplored acreage. In Argentina, the advancing development of the Vaca Muerta formation represents a meaningful component of the Company’s medium-term growth outlook, supported by GeoPark’s operational capabilities and regional experience.

Grupo Gilinski believes Venezuela may warrant renewed review and prioritization as the rapidly evolving conditions in the country could position it as a strategic opportunity for GeoPark. GeoPark’s regional operating experience and technical capabilities ideally position the Company to evaluate such opportunities responsibly should market conditions and regulatory frameworks continue to evolve favorably.

A Strategic Investor with a Proven Value Creation Track Record

Grupo Gilinski is one of Latin America’s most diversified global investment groups. Its investment experience includes:

• Active ownership positions in financial services, food, media, real estate and consumer businesses in Latin America and Europe.
• Experience supporting transformation and recapitalization processes in regulated institutions.
• Participation in cross-border capital markets transactions and governance oversight of publicly listed companies.

The Group has been involved in the transformation of Grupo Nutresa and in the recapitalization and restructuring of Metro Bank in the United Kingdom, among other transactions. In both instances, they acted as a decisive, constructive, long-term partner, providing capital, governance support and strategic oversight at critical inflection points, which ultimately generated meaningful value for all shareholders.

This transaction represents an important evolution in GeoPark’s ownership profile, introducing aligned and committed long-term institutional capital while preserving the Company’s diverse shareholder base and supporting GeoPark’s goal of maximizing value for all shareholders.

Governance Structure Reinforces Strategic Independence and Shareholder Protection

The transaction has been structured to ensure alignment with GeoPark’s long-term strategy while preserving strategic independence. The agreement includes:

• An 18-month lock-up period commitment, during which Colden cannot sell its shares.
• Approval rights over certain matters as long as Colden maintains a 15% minimum ownership stake.
• Ownership limitations for the next 12 months, requiring Board approval for any increase in ownership above 32% of shares outstanding.

Under the terms of the agreement, at its current 20% ownership level, Colden is entitled to nominate two directors to GeoPark’s nine-member Board, subject to customary corporate governance procedures in accordance with applicable law and NYSE listing standards. Should Colden’s ownership increase to 28% or more of the Company’s outstanding common shares, it would be entitled to nominate a third director.

At all times, the GeoPark Board will maintain a majority of independent directors. If entitled to nominate three directors, at least one of the Colden nominees must qualify as an independent director under NYSE standards and the Company’s governance framework.

Gabriel Gilinski will fill the current vacancy on GeoPark’s Board effective immediately. Mr. Gilinski holds a Bachelor’s Degree from the University of Pennsylvania and currently serves in senior leadership roles within Grupo Gilinski’s global investment platform. Mr. Gilinski has played an active role in capital allocation, cross-border financing and strategic repositioning initiatives across publicly listed and regulated institutions. He has extensive board and executive experience across financial services institutions in Latin America. He is chairman of the Board of Grupo Nutresa, one of the largest food companies in Latin America.

In light of the significant benefits of this transaction to GeoPark, the Board has agreed to waive the provisions of its Shareholder Rights Plan to permit Colden to acquire up to 32% of the Company’s shares. The Board considered the interests of all shareholders in evaluating this transaction, which is designed to preserve the rights of the Company’s broader shareholder base. The Board remains firmly committed to transparency, fairness and disciplined decision-making.

Enhanced Financial Flexibility

The Company intends to deploy this capital to:

• Pursue accretive M&A opportunities aligned with the Company’s strategy and return thresholds.
• Fund high-return organic development in Colombia and Argentina.
• Maintain balance-sheet strength and financial flexibility.
• Support other corporate initiatives consistent with long-term value creation.

The Company retains full discretion to deploy capital in a manner consistent with its return thresholds and strategic priorities. This transaction enhances GeoPark’s ability to execute on its growth roadmap with greater speed, scale and flexibility.

While the transaction increases the Company’s outstanding share count, the Board believes that strengthening its platform, expanding strategic capacity, and accelerating high-return initiatives will enhance long-term earnings power and drive sustainable per-share shareholder value creation.
