Protecting What We Have, Returning to Growth: Full-Year Guidance Delivered, Transformational Portfolio Reset Well Underway

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 December 31, 2025 ("Fourth Quarter" or "4Q2025") and for the year ended December 31, 2025 ("Full Year" or "FY2025"). A conference call to discuss these financial results will be held on February 26, 2026, at 10:00 am (Eastern Standard Time).

2025: DISCIPLINED DELIVERY IN A LOWER PRICE ENVIRONMENT

2025 was a transition year in a materially lower oil price environment. Brent averaged $68.2/bbl in FY2025 versus $79.8/bbl in FY2024, and $63.1/bbl in 4Q2025 versus $74.0/bbl in 4Q2024. In this context, GeoPark delivered or exceeded all key 2025 guidance metrics, including production, operating costs and capital expenditures. Average production reached 28,233 boepd in FY2025, above the upper end of the Company's 26,000–28,000 boepd guidance range. Operating costs averaged $13.2/boe, within the $12–14/boe guidance range, and capital expenditures totaled $98.4 million, consistent with the Company's disciplined capital program.

GeoPark furthermore executed key strategic milestones during the year: closing the acquisition of two high-quality Vaca Muerta blocks in October 2025 and initiating and advancing negotiations which allowed the Company to agree, in January 2026 to acquire Frontera Energy's Colombian upstream assets. Together, these transactions transform portfolio optionality and materially enhance scale, reserve base, and long-term cash flow capacity.

FINANCIAL PERFORMANCE: PRICE-DRIVEN EBITDA DECLINE; MARGINS REMAIN RESILIENT

FY2025 results primarily reflect lower realized prices and, to a lesser extent, lower average production. Combined realized price averaged $58.1/boe in FY2025 versus $65.6/boe in FY2024. Adjusted EBITDA¹ totaled $277.1 million compared to $416.9 million in FY2024. In 4Q2025, Adjusted EBITDA was $46.3 million (42% margin), compared to $71.4 million in 3Q2025 and $77.7 million in 4Q2024. Fourth Quarter performance was impacted by identifiable, non-recurring items, including deferred sales volumes expected to be realized in 1Q2026, logistics-related selling expense adjustments, and start-up and year-end costs associated with Vaca Muerta activity. Net profit totaled $31.1 million in 4Q2025 and $49.7 million for FY2025.

Operational performance across the portfolio remained solid during the year. Production stability was supported by resilient base production in the Llanos 34 Block, continued contribution from the CPO-5 Block, and successful drilling and appraisal activity in the Llanos 123 Block. The Company operated six rigs at year-end (three drilling and three workover) and drilled and completed 16 wells during 2025. Initial production from the acquired Vaca Muerta blocks also contributed during the Fourth Quarter.

RESILIENCE AND DISCIPLINE: STRUCTURAL COST RESET AND BALANCE SHEET STRENGTH

Structural cost reset

GeoPark delivered meaningful structural efficiencies in 2025. FY2025 operating costs averaged $13.2/boe (within guidance of $12–14/boe) and structure costs averaged $4.8/boe. Initiatives implemented during the year generated approximately $32 million in structural cash cost savings, establishing a lower cost base expected to generate approximately $45 million in annualized savings into 2026 and beyond. In 4Q2025, operating costs and structure costs increased to $15.8/boe and $5.6/boe, respectively, reflecting identifiable one-off items including asset reactivations, start-up costs and year-end accruals. Excluding these items, normalized operating costs would have been approximately $13/boe and normalized structure cost approximately $4.5/boe, consistent with the Company's structural trajectory. These impacts were transitory and do not alter the underlying cost base entering 2026.

Capital efficiency

Capital expenditures of $98.4 million in FY2025 were deployed in line with the Company's capital expenditure plan, focused on sustaining production, advancing secondary recovery and progressing appraisal activity. The Company generated 2.8x Adjusted EBITDA relative to capital expenditures and delivered 18% ROACE, underscoring disciplined, returns-based capital allocation.

Balance sheet and risk management

At December 31, 2025, cash and cash equivalents were $100.3 million and net leverage was 1.6x, with no principal maturities until January 2027. During the year, GeoPark repurchased $108.3 million principal amount of its 2030 Notes below par, generating a $10.2 million gain and approximately $9.5 million in annual cash interest savings. Approximately 84% of expected 2026 production has been hedged through three-way collars. Hedging has also been initiated for 2027, covering approximately 71% of expected 1Q2027 production and 60% of expected 2Q2027 production.

TRANSFORMATIONAL PORTFOLIO RESET WELL UNDERWAY: STRENGTHENING SCALE AND COMPETITIVENESS

During 2025, GeoPark executed a decisive portfolio reset under its strategy of Protecting What We Have and Returning to Growth, reinforcing its Colombian cash-generating base while establishing a new unconventional growth engine in Vaca Muerta, Argentina.

In October 2025, GeoPark closed the acquisition of two high-quality blocks in Vaca Muerta, securing a 100% WI in the Loma Jarillosa Este Block and 95% in the Puesto Silva Oeste Block, totaling more than 12,300 gross acres in the black oil window. The assets add 11.1 mmboe of 1P net reserves, 36.7 mmboe of 2P net reserves and 71.1 mmboe of 3P net reserves, with a clear development path toward approximately 20,000 boepd plateau production by year-end 2028, establishing a scalable, operated growth platform.

In January 2026, GeoPark agreed to acquire Frontera Energy's Colombian upstream assets, encompassing 17 blocks with expected production of approximately 40,000 boepd net to GeoPark in 2026. Upon closing, which is subject to regulatory approvals and customary closing conditions, the transaction is expected to immediately add approximately 99 mmboe of 1P reserves and 147 mmboe of 2P reserves, more than doubling GeoPark's consolidated reserves and significantly strengthening long-term cash flow visibility. On a pro forma basis, consolidated production is expected to exceed 90,000 boepd by 2028, with EBITDA of approximately $950 million — more than doubling GeoPark's previously communicated standalone outlook.

On February 23, 2026, Parex Resources ("Parex") announced that it has submitted a competing proposal to acquire all of Frontera Energy's Colombian upstream business. Frontera Energy's Board of Directors will evaluate Parex's proposal in accordance with the terms of the existing arrangement agreement, and GeoPark will determine its next steps based on Frontera Energy's decision.

GeoPark remains committed to its agreement to acquire these assets and has strong conviction in the merits of the transaction. The Company believes that, among other reasons, GeoPark's strong operating expertise makes it the strongest strategic fit for Frontera Energy's assets.

Together, these actions represent a transformational step-change in GeoPark's scale, reserve base and competitive positioning, reinforcing its Colombian foundation while adding a high-quality unconventional growth engine for the next cycle.

Capital Returns

The Board declared a quarterly cash dividend of $0.03 per share, payable on March 31, to shareholders of record at the close of business on March 11, 2026. Consistent with GeoPark's disciplined capital framework, the Board will reassess shareholder distributions following the peak investment phase and normalization of free cash flow.

CEO Comment

Felipe Bayon, Chief Executive Officer of GeoPark, said: "2025 was a year of disciplined execution in a materially lower oil price environment. While Adjusted EBITDA declined primarily due to lower realized prices, we delivered production above guidance, protected margins and strengthened the balance sheet. More importantly, we initiated a profound strategic reset of the Company. We protected and strengthened our Colombian cash-generating base while repositioning the portfolio through Vaca Muerta and the Frontera Energy transaction—improving scale, competitiveness and long-term optionality. We enter 2026 with a distinctive, industry-leading asset base, a structurally lower cost platform and clearer multi-year visibility. Our focus remains on disciplined execution, returns-based growth and sustainable value creation through the cycle."

² Reported in the 4Q2025 Operational Update.

³ ROACE is defined as last twelve-month operating profit divided by average capital employed. Capital employed is calculated as total assets minus current liabilities and adjusted for excess cash. Excess cash corresponds to the portion of cash and cash equivalents that exceeds the amount required to cover current liabilities with current assets. The non-recurring impairment charge recorded in the 2Q2025 related to the divestment of assets in Ecuador was excluded from LTM operating profit for the purpose of this calculation.

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 expected production, closing of the Frontera Energy acquisition transaction (including expected reserves, cash flow generated, pro forma production and target EBITDA as a result of the acquisition), returns-based growth and sustainable value creation. 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.
