A conference call to discuss these financial results will be held on May 16, 2024, at 10:00 am (Eastern Daylight Time).FIRST QUARTER 2024 SUMMARYIn 1Q2024, GeoPark delivered $111.5 million Adjusted EBITDA, an Adjusted EBITDA margin of 67%, and $30.2 million net profit that was 15% higher than in 1Q2023. Quarterly average oil and gas production in 1Q2024 reached 35,473 boepd, down 3% compared to 1Q2023, mainly due to the divestment of the Chilean business on January 18, 2024.GeoPark invested $48.8 million in capital expenditures in 1Q2024, 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 in 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 $2.3 in Adjusted EBITDA, and the return on average capital employed reached 35%.GeoPark ended 1Q2024 with a strong balance sheet, illustrating its sustained commitment to financial discipline. The cash position continued to strengthen and reached $150.7 million at the end of the quarter, while net leverage stood at 0.8x times and the debt profile remained robust with no principal maturities until January 2027.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 the first quarter and ended in April 2024, reducing shares outstanding by approximately 8%.Looking forward to the remainder of 2024, GeoPark’s activity set will be focused on continuing the development of its core operations in the Llanos 34 and CPO-5 blocks, incorporating into the portfolio the recently acquired Mata Mora and Confluencia assets in Vaca Muerta, and delineating the new plays opened in 2023 in the Llanos Basin in Colombia and in the Oriente Basin in Ecuador, and preparing new blocks for future exploration.Andrés Ocampo, Chief Executive Officer of GeoPark, said: “GeoPark delivered robust financial results in 1Q2024, underpinned by our long-standing commitment to capital efficiency. The recently announced access to Vaca Muerta creates an immediate inventory of quality drilling opportunities in one of the most productive oil and gas basins in the world. We are making steady progress towards the promised step-change in our underlying performance and growth path.”Supplementary information is available at the following link:https://s202.q4cdn.com/389131578/files/doc_financials/2024/q1/supplement-to-first-quarter-2024-results.pdfFIRST QUARTER 2024 HIGHLIGHTSOil and Gas Production and Operations1Q2024 average oil and gas production of 35,473 boepd reflected stable production in the Llanos 34 Block, but was impacted by localized blockades in the CPO-5 Block and maintenance activities in the Manati gas field (GeoPark non-operated, 10% WI)Production in the Manati gas field has been suspended since mid-March 2024, and is expected to be restored in late second quarter or early third quarter 2024GeoPark’s average production in April 2024 increased to approximately 37,500 boepd, reflecting higher production from successful development activities in the Llanos 34 and CPO-5 blocksRevenue, Adjusted EBITDA and Net ProfitRevenue of $167.4 millionAdjusted EBITDA of $111.5 million (67% Adjusted EBITDA margin)Operating profit of $84.0 million (50% operating profit margin)Cash flow from operations of $87.6 millionNet profit of $30.2 million ($0.55 earnings per share)Cost and Capital EfficiencyCapital expenditures of $48.8 million1Q2024 Adjusted EBITDA to capital expenditures ratio of 2.3xLast twelve-month return on average capital employed of 35%[1]Balance Sheet Reflects Financial QualityCash in hand of $150.7 millionNet leverage of 0.8x and no principal debt maturities until January 2027Accelerated Shareholder ReturnsCash dividends of $7.5 million (representing an annualized dividend of approximately $30 million, or a 6% dividend yield[2])Successful tender of 4.4 million shares (8% of outstanding shares) at a purchase price of $10 per share in April 2024Quarterly cash dividend of $0.147 per share, or approximately $7.5 million, payable on June 14, 2024, to the shareholders of record at the close of business on May 31, 2024CONSOLIDATED OPERATING PERFORMANCEa.

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 INFORMATIONThis 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
