Capitalized terms used in this Amendment No. 4 and not otherwise defined shall have the same meanings ascribed to them in the Schedule 13D. Except as specifically amended by this Amendment No. 4, the Schedule 13D is unchanged. Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following information: The information set forth in Item 6 to this Schedule 13D is incorporated by reference. On September 2, 2026, Panamerican Energy Holdings, S.A., a corporation incorporated under the Laws of Panama ("PEH") and an affiliate of the Reporting Persons, entered into a Share Purchase Agreement (the "SPA"), whereby PEH agreed to sell to GeoPark USA, LLC, a limited liability company incorporated under the Laws of Delaware and a wholly owned subsidiary of the Issuer, 95% of the total issued share capital of Energy Assets International, S.A., a Panama sociedad anonima ("EAI"), in exchange for a number of newly issued Common Shares of the Issuer, ranging between 42,135,872 to 47,557,461 Common Shares (the "Additional GeoPark Shares"), depending on the applicable CIT rate in Venezuela at the time of closing (the "Miranda Transaction"). The Additional GeoPark Shares will be issued to PEH upon closing of the Miranda Transaction. Closing of the Miranda Transaction will occur upon fulfillment of certain standard conditions precedent including, but not limited to, the parties obtaining appropriate governmental and other approvals or licenses, and the Production Participation Contract between Beta Resources (V), C.A. and PDVSA Petroleo S.A., with respect to the "Bare Block" located in the Orinoco Oil Belt of Venezuela, becoming effective. The SPA also includes certain customary covenants and interim operating covenants including with respect to the treatment of the Issuer's debt instruments in the event of a change of control. Following the closing of the Miranda Transaction, the Reporting Persons are expected to become the controlling shareholder of the Issuer. The information set forth in Rows 11 and 13 of the cover pages to this Schedule 13D is incorporated by reference. The percentage of Common Shares outstanding is calculated based on 64,896,377 Common Shares issued and outstanding as of June 30, 2026, as reported in the Issuer's Current Report on Form 6-K dated August 5, 2026. Item 6 of the Schedule 13D is hereby amended and supplemented by adding the following information: The information set forth in Item 4 to this Schedule 13D is incorporated by reference. Simultaneously with the execution of the SPA, on September 2, 2026, the Issuer, PEH and Colden, entered into a Governance Agreement (the "Governance Agreement"), to govern the respective rights and obligations of PEH and Colden, as applicable, as Beneficial Owners of the Common Shares of the Issuer. Pursuant to the Governance Agreement, among other things (i) PEH was granted approval rights over certain corporate matters for so long as PEH and its affiliates beneficially own at least 15% of the outstanding Common Shares, (ii) subject to PEH and its affiliates meeting certain ownership thresholds described below, PEH was granted the right to nominate up to five individuals to the board of directors of the Issuer (the "Board"), and (iii) PEH was granted customary registration rights, including certain demand and piggyback registration rights with respect to underwritten offerings by the Issuer. Pursuant to the Governance Agreement, PEH has an obligation to launch a post-closing tender offer to purchase any and all issued and outstanding equity securities of the Issuer within 90 days at $12.22 per share (capped at $100 million in aggregate). If PEH or its affiliates later cross a 70% ownership threshold, they must commence a further tender offer at a price no less than the 30-day volume weighted average trading price. Pursuant to the Governance Agreement, for so long as PEH and its affiliates beneficially own at least 15% of the outstanding Common Shares, PEH's consent is required for the Issuer to (i) issue equity securities in excess of 5% of the Issuer's fully diluted share capital; (ii) make certain amendments to the governing documents of the Issuer; (iii) enter into certain related party transactions; (iv) change the size of the Board; (v) declare dividends other than pursuant to the Issuer's existing dividend policy; or (vi) redeem any of the Issuer's outstanding share capital. Additionally, pursuant to the Governance Agreement, PEH is entitled to nominate (i) one individual to the Board so long as it and its affiliates beneficially own at least 7.5% of the outstanding Common Shares, (ii) two individuals to the Board so long as it and its affiliates beneficially own at least 15% of the outstanding Common Shares, (iii) three individuals to the Board so long as it and its affiliates beneficially own at least 28% of the outstanding Common Shares, (iv) four individuals to the Board so long as it and its affiliates beneficially own at least 40% of the outstanding Common Shares, and (v) at least five individuals to the Board as long as it and its affiliates beneficially own at least 50% of the outstanding Common Shares. The Governance Agreement will be effective as of the closing of the SPA and, once effective, the governance rights and obligations of Colden and the Issuer under the Purchase Agreement will be superseded and replaced by those in the SPA.
