GeoPark Reports Second Quarter 2024 Results Bogota, Colombia August 14, 2024 STABLE PRODUCTION UNDERPINS STRONG CASH FLOW GENERATION ACQUISITION IN VACA MUERTA EFFECTIVE JULY 1 QUARTERLY CASH DIVIDEND OF $0.147 PER SHARE GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), a leading independent Latin American oil and gas explorer, operator, and consolidator, reports its consolidated financial results for the three-month period ended June 30, 2024 (“Second Quarter” or “2Q2024”). A conference call to discuss these financial results will be held on August 15, 2024, at 10:00 am (Eastern Daylight Time). SECOND QUARTER 2024 FINANCIAL SUMMARY In 2Q2024, GeoPark delivered $127.9 million Adjusted EBITDA[1] , a margin of 67%, and $25.7 million net profit. Quarterly average oil and gas production in 2Q2024 reached 35,608 boepd, down 3% compared to 2Q2023, mainly due to the divestment of the Chilean business on January 18, 2024, and suspended production at the Manati gas field in Brazil (GeoPark non-operated, 10% WI) due to unscheduled maintenance. GeoPark invested $49.2 million in capital expenditures in 2Q2024, focused on i) continuing the development of its core operations in the Llanos 34 (GeoPark operated, 45% WI) and CPO-5 (GeoPark non-operated, 30% WI) blocks in Colombia; ii) delineating the new plays opened in 2023 in the Llanos Basin in Colombia and the Oriente Basin in Ecuador and iii) preparing the new Llanos 86 and 104 blocks (GeoPark operated, 50% WI) for future exploration. Capital efficiency was once again a key feature of the quarter. Each dollar invested in capital expenditures yielded $2.6 in Adjusted EBITDA, and the return on average capital employed reached 38%. These financial achievements and discipline allowed GeoPark to continue rewarding its shareholders with quarterly dividends of $7.5 million ($0.147 per share) and a successful tender offer of 4.4 million shares at $10 per share that was launched in 1Q2024 and ended in April 2024, reducing shares outstanding by approximately 8%. Undersubscription to the tender offer demonstrated shareholder confidence. GeoPark’s acquisition in Vaca Muerta was effective July 1, 2024, and is expected to close by the end of the third quarter. The acquisition adds to pro forma production, taking consolidated pro forma production to more than 41,000 boepd as of the effective date. Following 12,508 bopd gross average production in 2Q2024 from the unconventional development wells in the Mata Mora Norte Block (GeoPark non-operated, 45% WI), the operator is currently drilling three unconventional exploration wells in the Confluencia Norte Block (GeoPark non-operated, 50% WI) aimed at derisking the full potential of the block. Andrés Ocampo, Chief Executive Officer of GeoPark, said: “GeoPark again delivered strong financial performance in 2Q2024, underscoring the effectiveness of our strategic initiatives and disciplined approach to capital allocation, while maintaining a robust balance sheet. In the second half of 2024, we look forward to the continued development of our core operations in Colombia and Ecuador, and the integration of our newly acquired assets in Vaca Muerta. Our strategy remains centered on delivering consistent value to our shareholders through prudent financial management and targeted growth initiatives.” Supplementary information is available at the following link: https://ir.geo-park.com/2Q24-SupplementaryRelease/ SECOND QUARTER 2024 HIGHLIGHTS Oil and Gas Production and Operations • 2Q2024 consolidated average oil and gas production of 35,608 boepd[2] • Production increased 11% in Ecuador and 3% in Colombia, offsetting suspended production at the Manati gas field in Brazil due to unscheduled maintenance • Llanos 34 Block average production in 2Q2024 was 3% lower than 1Q2024 due to sporadic blockades, weather-associated flooding, and base decline, partly offset by new well production • The CPO-5 Block reached record average production in 2Q2024 after putting the Indico 3 well on production. The Lark 1 exploration well reached total depth in late July 2024 with no hydrocarbons in the targeted Ubaque and Guadalupe formations, and the well was abandoned • 10 rigs in operation at the end of 2Q2024 (6 drilling rigs and 4 workover rigs), including one drilling rig in Argentina Revenue, Adjusted EBITDA and Net Profit • Revenue of $190.2 million, an increase of 14% from 1Q2024, reflecting higher realized oil prices • Adjusted EBITDA of $127.9 million (67% Adjusted EBITDA margin), an increase of 15% from 1Q2024 • Operating profit of $90.3 million (47% Operating profit margin), an increase of 8% from 1Q2024 • Net profit of $25.7 million, a decrease of 15% from 1Q2024 mainly due to the effect of the devaluation of Colombian peso on deferred income taxes Cost and Capital Efficiency • Capital expenditures of $49.2 million • 2Q2024 Adjusted EBITDA to capital expenditures ratio of 2.6x • Last twelve-month return on average capital employed of 38%[3] Balance Sheet Reflects Financial Quality • Cash in hand of $66.0 million, after repurchasing outstanding shares worth $43.7 million, making a $49.1 million advanced payment for the Vaca Muerta acquisition in Argentina, and paying $52.5 million income tax (Colombia 2023 full amount) • Net leverage remained healthy (0.9x), with no principal debt maturities until January 2027 • Current cash position of $85.8 million (July 31, 2024) • Fitch Ratings revised GeoPark’s rating outlook to stable (from negative), reflecting the increase in reserves and improved geographic footprint resulting from the Vaca Muerta acquisition in Argentina Growing Shareholder Returns • Cash dividends of $7.5 million (representing an annualized dividend of approximately $30 million, or a 6.8% dividend yield[4] ) • Successful tender of 4.4 million shares (8% of outstanding shares) at a purchase price of $10 per share on April 2024 • Quarterly cash dividend of $0.147 per share payable on September 12, 2024, to shareholders of record at the close of business on August 29, 2024 Commercial Agreements Improve Price Realizations and Add Financial Flexibility • Vitol Agreement: Commercial agreement in effect as of July 1, delivering production from the Llanos 34 Block and improving price realizations by $0.60/barrel vs the average price realizations from January 2021 to July 2024. Access to committed funding for up to $300 million, with an option to increase by another $200 million for a total of $500 million, in prepaid future oil sales over the period of the offtake contract. As of today, GeoPark has not drawn any amounts for prepaid sales • Trafigura Agreement: New commercial agreement in effect as of August 1, delivering production from the CPO-5 Block and improving price by $2.65/barrel vs the average price realizations from January 2021. This agreement is associated with a prepayment facility for up to $100 million of financing to be repaid in future oil sales over the period of the offtake contract (12 months). Upon completion of the legal documentation, the prepayment agreement will provide GeoPark with immediate liquidity that will further strengthen its balance sheet and expand existing cash availability. As of today, GeoPark has not drawn any amounts for prepaid sales and the prepayment facility is subject to final signature of the contracts 2H2024 PRODUCTION UPDATE During 1H2024, GeoPark averaged 35,540 boepd production, at the lower end of the 35,500-39,000 boepd organic production range indicated for 2024. During 2H2024, the main risks to production are (i) increased uncertainty around the effective restart date of the Manati field, originally planned by end of May 2024, and now expected by the operator to initiate end of October, (ii) new well activity and performance in the Llanos 34 Block may not offset the natural base decline of the fields, and (iii) increased frequency and duration of blockades around the operations in Colombia. The downside associated to these risks could be approximately 1,500 – 2,500 boepd. Potential positive results from ongoing exploration drilling in the Llanos 123, Espejo, and PUT-8 Blocks (GeoPark operated, 50% WI) may offset the impact of these risks and have not been included in the 2024 guidance. GeoPark will continue the appraisal drilling campaign by adding wells in the CPO-5 and Llanos 123 blocks. Importantly, since July 1, production from the Vaca Muerta blocks in Argentina belongs to GeoPark and is already at 5,000 – 5,500 boepd net. These volumes will be consolidated on a line-by-line basis once the transaction is closed (expected by the end of September). Current production levels do not include the potential result from the 2H2024 development drilling campaign in Mata Mora Norte, nor the outcome of three exploration wells to be completed in Confluencia Norte. GeoPark’s Adjusted EBITDA guidance of $420 – $550 million[5] remains unchanged for 2024. CONSOLIDATED OPERATING PERFORMANCE Key performance indicators: Includes royalties and other economic rights paid in kind in Colombia for approximately 6,956 bopd, 5,916 bopd, and 2,952 bopd in 2Q2024, 1Q2024 and 2Q2023, respectively. No royalties were paid in kind in other countries. Production in Ecuador is reported before the Government’s production share.

Rounding amounts and percentages: Certain amounts and percentages included in this press release and its supplementary information have been rounded for ease of presentation. Percentage figures included in this press release and its supplementary information have not in all cases been calculated on the basis of such rounded figures, but on the basis of such amounts prior to rounding. In addition, certain other amounts that appear in this press release and its supplementary information may not sum due to rounding. This press release and its supplementary information contain certain oil and gas metrics, including information per share, operating netback, reserve life index and others, which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies. Such metrics have been included herein to provide readers with additional measures to evaluate the Company’s performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods. CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION This press release and its supplementary information contain statements that constitute forward-looking statements. Many of the forward-looking statements contained in this press release can be identified by the use of forward-looking words such as ‘‘anticipate,’’ ‘‘believe,’’ ‘‘could,’’ ‘‘expect,’’ ‘‘should,’’ ‘‘plan,’’ ‘‘intend,’’ ‘‘will,’’ ‘‘estimate’’ and ‘‘potential,’’ among others. Forward-looking statements that appear in a number of places in this press release include, but are not limited to, statements regarding the intent, belief or current expectations, regarding various matters, including, the drilling campaign and share buyback program. Forward-looking statements are based on management’s beliefs and assumptions, and on information currently available to the management. Such statements are subject to risks and uncertainties, and actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors. Forward-looking statements speak only as of the date they are made, and the Company does not undertake any obligation to update them in light of new information or future developments or to release publicly any revisions to these statements in order to reflect later events or circumstances, or to reflect the occurrence of unanticipated events. For a discussion of the risks facing the Company which could affect whether these forward-looking statements are realized, see filings with the U.S. Securities and Exchange Commission (SEC). Oil and gas production figures included in this press release and its supplementary information are stated before the effect of royalties paid in kind, consumption and losses. Annual production per day is obtained by dividing total production by 365 days. Non-GAAP Measures: The Company believes Adjusted EBITDA, free cash flow and operating netback per boe, which are each non-GAAP measures, are useful because they allow the Company to more effectively evaluate its operating performance and compare the results of its operations from period to period without regard to its financing methods or capital structure. The Company’s calculation of Adjusted EBITDA, free cash flow, and operating netback per boe may not be comparable to other similarly titled measures of other companies. Adjusted EBITDA: The Company defines Adjusted EBITDA as profit for the period before net finance costs, income tax, depreciation, amortization and certain non-cash items such as impairments and write-offs of unsuccessful exploration and evaluation assets, accrual of stock options and stock awards, unrealized results on commodity risk management contracts and other non-recurring events. Adjusted EBITDA is not a measure of profit or cash flow as determined by IFRS. The Company excludes the items listed above from profit for the period in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, profit for the period or cash flow from operating activities as determined in accordance with IFRS or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure and significant and/or recurring write-offs, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDA. For a reconciliation of Adjusted EBITDA to the IFRS financial measure of profit, see the accompanying financial tables and the supplementary information. Operating Netback per boe: Operating netback per boe should not be considered as an alternative to, or more meaningful than, profit for the period or cash flow from operating activities as determined in accordance with IFRS or as an indicator of the Company’s operating performance or liquidity. Certain items excluded from operating netback per boe are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure and significant and/or recurring write-offs, as well as the historic costs of depreciable assets, none of which are components of operating netback per boe. The Company’s calculation of operating netback per boe may not be comparable to other similarly titled measures of other companies. SHARE
