Resilient Results Amid Lower Production Volumes and Brent Cost and Capital Efficiency Measures Well Underway

Divesting Non-Core Assets in Ecuador

Quarterly Cash Dividend of $0.147 Per Share

GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), a leading independent energy company with over 20 years of successful operations across Latin America, reports its consolidated financial results for the three-month period ended June 30, 2025 (“Second Quarter” or “2Q2025”). A conference call to discuss these financial results will be held on August 6, 2025, at 10:00 am (Eastern Daylight Time).

GeoPark delivered solid financial and operational results in 2Q2025, despite a lower oil price environment. Strong execution, proactive cost management and disciplined capital allocation supported results, while enabling continued investment in high-return projects within the Company’s core portfolio. Consistent with its strategic priorities, GeoPark focused on strengthening its balance sheet and protecting financial flexibility to navigate a lower oil price environment and position the Company for long-term, value-accretive growth.

SECOND QUARTER 2025 FINANCIAL SUMMARY

In 2Q2025, GeoPark reported Adjusted EBITDA¹ of $71.5 million (60% margin), a 19% decrease compared to 1Q2025, mainly due to a 9% drop in realized prices and a 6% decrease in production volumes, partially offset by an 8% reduction in production and operating costs, which remained at $12.3 per barrel of produced boe.

Net loss for the quarter totaled $10.3 million compared to a $13.1 million profit in 1Q2025, primarily reflecting a non-recurring impairment charge related to the divestment of assets in Ecuador. As part of its ongoing portfolio review, GeoPark agreed to divest its 50% working interest (“WI”) in the Perico and Espejo Blocks in Ecuador for a total cash consideration of $7.8 million. The closing of the divestment transaction is subject to regulatory approvals.²

Excluding the non-recurring impairment, net profit for the quarter amounted to $20.7 million, 58% higher than 1Q2025, reflecting lower depreciation, financial expenses and income tax. The effective tax rate for 2Q2025 was 27%, below the statutory income tax rate of 35% in Colombia, primarily due to the re-estimation of the oil and gas sector surcharge, which was reduced from 5% to 0% in response to the lower oil price environment.

Capital expenditures in 2Q2025 totaled $23.9 million, primarily directed toward the execution of the integrated drilling and workover campaign in the Llanos 34 Block (GeoPark operated, 45% WI), enhancing operational efficiency and maintaining stable production levels. In parallel, an exploration and appraisal campaign continued in the Llanos 123 Block (GeoPark operated, 50% WI), supported by the construction of key infrastructure.

At the end of the second quarter, the Company had $266.0 million cash in hand, while net debt stood at $359.5 million with a low leverage ratio of 1.1x, reflecting a robust capital structure.

To mitigate downside risk from oil price volatility, the Company continues to proactively manage its hedging strategy. For 2025, approximately 87% of expected production is hedged with price floors between $68–70/bbl, resulting in a $4.9 million gain reflected in 2Q2025 revenue. As of August 5, 2025, oil price protection for 2026 has also been secured through 3-way collars, for approximately 9,000 boepd of 1H2026 and 8,000 boepd of 2H2026 production, with average strike prices at $50/$65/$74.

Reflecting the Company’s performance during the quarter, the Board of Directors declared a quarterly cash dividend of $0.147 per share (approximately $7.5 million), payable on September 4, 2025. In parallel, the Board is actively reviewing the Company’s capital allocation priorities, including dividend distribution going forward in the context of evolving strategic priorities and the need to preserve flexibility to pursue value-accretive growth opportunities. This review will continue over the coming months as part of our ongoing overall financial and strategic positioning.

COST AND CAPITAL EFFICIENCY MEASURES

GeoPark is implementing several cost and capital efficiency initiatives to further enhance value and maximize long term competitiveness. These initiatives also reflect the Company’s clear intent to preserve financial firepower for ongoing inorganic growth initiatives, while navigating continued Brent price volatility. The measures are the following:

Cost Efficiencies

The Company has implemented a comprehensive efficiency program to align the cost structure with current activity levels. The goal is to ensure a competitive organization that maximizes value from the existing portfolio, while preserving the distinctive capabilities necessary to pursue long term reserves renewal and incremental shareholder value. By the end of July 2025, the Company had already captured $12.5 million in efficiencies. On an annualized basis, such efficiencies represent approximately $17.5 million of structural savings going forward.

Debt Reduction

Underscoring its disciplined approach to capital allocation and balance sheet optimization, the Company repurchased $54.5 million of its 2030 Notes in June and July 2025 at an average price of $0.88 and $0.89 on the dollar, respectively, through open market transactions. These repurchases generate coupon savings of approximately $5 million annually (or over $20 million until the Notes’ maturity in 2030) while enhancing long-term financial flexibility. The Company will continue to actively monitor market conditions to opportunistically pursue further value-accretive liability management initiatives, subject to available liquidity and overall capital allocation priorities.

Felipe Bayon, Chief Executive Officer of GeoPark, said: “My first two months at GeoPark have been an intense and rewarding period of learning, listening, and engaging closely with our teams and operations. I have encountered a company with a very solid operating platform and a deeply committed team, and these strong foundations have allowed us to continue delivering resilient results, despite today’s complex and volatile environment. Our second quarter results were slightly ahead of our existing guidance, and we are actively reassessing our portfolio and cost structure, prioritizing capital allocation, divesting non-core assets and exploring new organic and inorganic opportunities to generate value. With focus, agility, and the right decisions, I’m confident we can write GeoPark’s next growth chapter.”

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 liability management initiatives, hedging of expected production, full year net leverage figures, strategic initiatives, growth and capital allocation, and the divestment transaction in Ecuador. 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.
