GEOPARK REPORTS THIRD QUARTER 2025 RESULTS

STRONG OPERATIONAL AND FINANCIAL DELIVERY IN LINE WITH 2025 GUIDANCE

SEAMLESS TAKEOVER OF THE VACA MUERTA OPERATION

QUARTERLY CASH DIVIDEND OF $0.03 PER SHARE

ESTABLISHES SPECIAL COMMITTEE OF INDEPENDENT DIRECTORS TO EVALUATE ANY REVISED OFFER FROM PAREX AND OTHER VALUE-MAXIMIZING ALTERNATIVES FOR THE COMPANY

Bogota, Colombia – November 5, 2025 - 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 September 30, 2025 (“Third Quarter” or “3Q2025”). A conference call to discuss these financial results will be held on November 6, 2025, at 10:00 am (Eastern Standard Time).

GeoPark delivered a strong quarter, driven by higher production, stable prices, and disciplined cost control, in line with 2025 guidance. The Company continued to strengthen its balance sheet through proactive debt management and robust cash generation while advancing its strategic priorities by successfully completing the Vaca Muerta acquisition and launching a revised dividend program.

On October 21, 2025, GeoPark presented its long-term strategic plan, operational priorities and updated capital allocation framework, outlining a clear two-fold reset strategy to (i) sustain a resilient, high-margin base in Colombia and (ii) scale a transformational growth platform in Argentina’s Vaca Muerta formation. The plan sets an outlook through 2030, targeting consolidated production of approximately 42,000–46,000 boepd, Adjusted EBITDA between $520–550 million, and a net leverage ratio of 0.8–1.0x¹. The strengthening of the Company’s balance sheet and its long-term strategic plan reinforce GeoPark’s commitment to disciplined sustainable growth, portfolio diversification, shareholder returns and long-term value creation.

THIRD QUARTER 2025 FINANCIAL SUMMARY

In 3Q2025, GeoPark reported Adjusted EBITDA² of $71.4 million (57% margin), broadly stable versus 2Q2025, explained by higher production during the quarter (28,136 boepd vs 27,380 boepd in 2Q2025) and the stability of realized prices ($57.1/bbl vs $57.4/bbl in 2Q2025). Operating costs stood at a competitive $12.5 per barrel of produced boe, in line with 2Q2025 and overall market guidance for 2025. Year-to-date Adjusted EBITDA amounted to approximately $230.0 million, supported by higher production and lower operational and G&A costs across the business, reflecting the early impact of the cost discipline and efficiency initiatives underway.

¹ The Company is unable to present a quantitative reconciliation of the target Adjusted EBITDA which is a forward-looking non-GAAP measure, because the Company cannot reliably predict certain of its necessary components, such as write-off of unsuccessful exploration efforts or impairment loss on non-financial assets, etc. Since net leverage ratio is calculated based on Adjusted EBITDA, for similar reasons, the Company does not provide a quantitative reconciliation of the target net leverage ratio.

² For reconciliations, see “Reconciliation of Adjusted EBITDA to Profit Before Income Tax” table below.

Net income for the quarter totaled $15.9 million, compared to a net loss of $10.3 million in 2Q2025. This result for the quarter accounts for a non-recurring write-off of $7.5 million related to exploration costs incurred in previous years in the Putumayo Basin in Colombia. Excluding the non-recurring events in each of 2Q2025 and 3Q2025³, net profit in 3Q2025 was $23.4 million compared to $20.7 million in 2Q2025.

Capital expenditures totaled $17.5 million in 3Q2025, primarily focused on maintaining and improving production through an integrated drilling and workover campaign in the Llanos 34 block (GeoPark operated, 45% WI). At the same time, activities progressed on multiple fronts across GeoPark’s exploration assets in the Llanos basin. During the quarter, the Company advanced drilling operations on the Toritos Norte 3 well in the Llanos 123 block (GeoPark operated, 50% WI) and continued infrastructure development on key platforms in Puerto Gaitán, laying a solid foundation for the upcoming drilling campaign in the Llanos 104 block.

Since the closing of the Vaca Muerta acquisition on October 16, 2025, the Company has safely and efficiently taken over the operations, ensuring seamless operational continuity, and within less than 10 days has started delivering on its plan by commencing workover activities to install rod pumps in 3 wells in the Loma Jarillosa Este block to improve productivity. Crude is being sold locally, and procurement is underway to secure the activity plan for 2026. Additionally, the Company is identifying multiple cost efficiency and synergy opportunities to accelerate development, optimize returns and unlock additional value.

The Company continued to generate strong operating cash flow during the quarter, supported by the efficiency initiatives implemented in 2Q2025. This solid performance enabled GeoPark to fully fund its investment program, reduce debt, distribute dividends, and make an early payment related to the Vaca Muerta acquisition⁴. As a result, at the end of 3Q2025, GeoPark’s cash in hand stood at $197.0 million.

During the quarter, GeoPark repurchased and cancelled $33.0 million in aggregate principal of its 2030 Notes at an average price of $0.90 on the dollar. In total, between June and October, the Company repurchased $108.3 million in aggregate principal of its 2030 Notes, resulting in annual cash coupon savings of $9.5 million. Net debt stood at $373.4 million at the end of 3Q2025, with a low leverage ratio of 1.2x, reflecting a robust capital structure.

To mitigate downside risk from oil price volatility, the Company continues to proactively manage its hedging strategy. As of the date hereof, oil price protection for 2026 has been secured through 3-way collars, for approximately 62% of full-year production, with a first floor at $65/bbl, a second floor at $50/bbl and average ceilings of $73/bbl.

As announced on October 21, 2025, ahead of the Company’s Investor Day, and following the completion of the Vaca Muerta acquisition, the Board approved a revised dividend program including a total expected distribution of approximately $6 million over the next four quarters, equivalent to $1.5 million per quarter (or $0.03 per share), commencing with the 3Q2025 results payout and ending with the 2Q2026 results payout. Dividends will be suspended commencing with the 3Q2026 results, aligned with increased capital expenditures for Vaca Muerta. The Board will reassess dividends once positive free cash flow generation resumes after the peak investment phase, consistent with GeoPark’s disciplined, returns-based capital framework.

Looking ahead, GeoPark is on track to release its 2026 Work Program and Investment Guidelines before year-end. This plan will reflect the Company’s renewed strategic direction—focused on building and maximizing value delivery from its high-margin base in Colombia, and new operated assets in Vaca Muerta.

Felipe Bayon, Chief Executive Officer of GeoPark, said: “Our third-quarter results underscore the strength and resilience of GeoPark’s business model and the confidence with which we are executing our strategy — delivering operational excellence, disciplined capital allocation, and profitable growth. With a robust balance sheet, a clear plan, and a portfolio of high-quality and distinctive assets that combines stable cash generation in Colombia with transformative growth in Argentina, GeoPark is well positioned to maximize value and deliver sustainable returns for our shareholders.”

³ The non-recurring write-off in 3Q2025 and the non-recurring impairment charge related to the divestment of assets in Ecuador announced in 2Q2025.

⁴ In September, GeoPark paid a $22.7 million security deposit for the acquisition of a 100% operated working interest in the Loma Jarillosa Este and Puesto Silva Oeste blocks in Vaca Muerta. Following the closing of the acquisition on October 16, 2025, the Company paid the remaining $92.3 million of the upfront amount in cash.

UPDATE ON ENGAGEMENT WITH PAREX RESOURCES

As communicated in GeoPark’s press release of October 29, 2025, the GeoPark Board is open to opportunities that fairly reflect the Company’s value, strategy, and long-term potential. Following a robust process, the Board unanimously determined that the unsolicited, non-binding proposal of $9.00 per share submitted by Parex Resources (“Parex”) on September 4, 2025, prior to the announcement of GeoPark’s transformative acquisition in Vaca Muerta, undervalues GeoPark, fails to reflect its growth prospects and diversified portfolio, and is not in its shareholders’ best interests.

Following Parex’s public reiteration of its $9.00 per share offer, the Board unanimously agreed that Felipe Bayon should further engage with Parex and provide additional information to help it improve its offer. In addition, GeoPark’s Board of Directors has formed a Special Committee of independent directors, including Sylvia Escovar Gomez, Constantin Papadimitriou, Somit Varma and Brian Maxted, to evaluate any potential revised offer from Parex and other value-maximizing alternatives for the Company. GeoPark does not intend to make any further public comment on the process unless and until it determines that further disclosure is appropriate.

⁶ 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 full year guidance, five-year outlook target figures, hedging of expected production, full year net leverage figures, strategic initiatives, growth and capital allocation, drilling campaign, release of 2026 Work Program and Investment Guidelines. 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.

Item 2

SUPPLEMENT TO THIRD QUARTER 2025 RESULTS RELEASE

This document should be read in conjunction with GeoPark’s Third Quarter 2025 Results Release, available on the Company’s website.

PRODUCTION, DELIVERIES AND REALIZED OIL PRICES

Production: Average net oil and gas production in 3Q2025 was 28,136 boepd, down 15% compared to 3Q2024 mainly due to the natural decline in our core Llanos 34 Block (GeoPark operated, 45% WI), the operational suspension of the Platanillo Block¹ and the divestment of the Llanos 32 Block (GeoPark non-operated, 12.5% WI²). Oil represented 96.5% and 99.6% of total reported production in 3Q2025 and 3Q2024, respectively.

For further details, please refer to the 3Q2025 Operational Update published on October 20, 2025.

Deliveries: Oil and gas deliveries to GeoPark’s offtakers in 3Q2025 totaled 23,817 boepd, down by 11% compared to 3Q2024, mainly due to lower production.

Reference and Realized Oil Prices: Brent crude oil prices averaged $68.1 per bbl during 3Q2025, and the consolidated realized oil sales price decreased by 10% to $60.6 per bbl in 3Q2025, compared to 3Q2024.

A breakdown of reference and net realized oil prices in relevant countries in 3Q2025 and 3Q2024 is shown in the tables below:

REVENUE AND COSTS

Revenue: Consolidated revenue decreased by 22% to $125.1 million in 3Q2025, compared to $159.5 million in 3Q2024, mainly reflecting lower realized oil and gas prices and lower deliveries.

Sales of crude oil: Consolidated oil revenue decreased by 23% to $120.6 million in 3Q2025, mainly due to a 10% decrease in realized oil prices and a 14% decrease in deliveries. Oil revenue was 96% and 99% of total revenue in 3Q2025 and 3Q2024, respectively.

The table below provides a breakdown of crude oil revenue in 3Q2025 and 3Q2024:


Oil Revenue (In millions of $)	3Q2025	3Q2024
Colombia	115.7	147.6
Ecuador	4.7	9.9
Brazil	0.1	—
Oil Revenue	120.6	157.5

Sales of purchased crude oil: No sales of purchased crude oil were recorded in 3Q2025, compared to $1.5 million in 3Q2024. This corresponds to oil trading operations (purchasing and selling crude oil from third parties with the cost of the oil purchased reflected in production and operating costs).

Sales of gas: Consolidated gas revenue was $3.0 million in 3Q2025, compared to $0.5 million in 3Q2024, mainly reflecting resumed production at the Manati gas field in Brazil.

The table below provides a breakdown of gas revenue in 3Q2025 and 3Q2024:


Gas Revenue (In millions of $)	3Q2025	3Q2024
Colombia	—	0.5
Brazil	3.0	—
Gas Revenue	3.0	0.5

Commodity Risk Management Contracts: Commodity risk management contracts, which are designated and qualify as cash flow hedges, amounted to a $1.5 million gain in 3Q2025, compared to zero in 3Q2024.

In 3Q2025, GeoPark had zero cost collars covering 17,500 bopd including purchased puts with an average price of $68.7 per bbl and sold calls at an average price of $78.6 per bbl.

Please refer to the “Commodity Risk Management Contracts” section below for a description of hedges in place.

Production and Operating Costs: Consolidated production and operating costs decreased to $33.3 million in 3Q2025 from $39.8 million in 3Q2024, mainly resulting from lower operating costs and lower crude oil purchased from third parties.

The table below provides a breakdown of production and operating costs in 3Q2025 and 3Q2024:


Production and Operating Costs (In millions of $)	3Q2025	3Q2024
Operating costs	(31.4)	(36.0)
Royalties paid in cash	(1.4)	(1.0)
Economic rights paid in cash	(0.4)	(1.3)
Purchased crude oil	—	(1.4)
Share-based payments	(0.1)	(0.2)
Production and Operating Costs	(33.3)	(39.8)

Consolidated operating costs amounted to $31.4 million in 3Q2025, compared to $36.0 million in 3Q2024.

The table below provides the operating cost on a per boe basis in 3Q2025 and 3Q2024:


Operating Costs (Per boe)^a	3Q2025	3Q2024
Operating costs per produced boe	(12.5)	(12.4)
Operating costs per sold boe	(15.0)	(15.4)

a)	Operating costs per boe included in this table include certain adjustments to the reported figures (IFRS 16 and others).

Consolidated royalties paid in cash amounted to $1.4 million in 3Q2025, compared to $1.0 million in 3Q2024.

Consolidated economic rights paid in cash (including high price participation, x-factor and other economic rights paid to the Colombian Government in cash) amounted to $0.4 million in 3Q2025, compared to $1.3 million in 3Q2024.

No consolidated purchased crude oil charges were recorded in 3Q2025, compared to $1.4 million in 3Q2024, which corresponds to oil trading operations (purchasing and selling crude oil from third parties with the sale of purchased oil being reflected in revenue).

Selling Expenses: Consolidated selling expenses increased to $7.2 million in 3Q2025, compared to $3.5 million in 3Q2024. The fluctuation in transportation costs is mainly attributed to deliveries at different sales points in the CPO-5 Block in Colombia, including the shift to export delivery locations under a new commercial arrangement with BP since August 2025. Sales at the wellhead incur no selling costs but yield lower revenue, while transportation expenses for sales to alternative or export delivery points are recognized as selling expenses.

Geological & Geophysical Expenses: Consolidated G&G expenses decreased slightly to $2.3 million in 3Q2025, compared to $3.0 million in 3Q2024.

Administrative Expenses: Consolidated G&A decreased to $9.8 million in 3Q2025 compared to $12.7 million in 3Q2024.

Adjusted EBITDA: Consolidated Adjusted EBITDA³ decreased by 28% to $71.4 million in 3Q2025 compared to 3Q2024. On a per boe basis, Adjusted EBITDA decreased to $32.6 per boe in 3Q2025 from $40.7 per boe in 3Q2024.


Adjusted EBITDA (In millions of $)	3Q2025	3Q2024
Colombia	70.9	99.7
Ecuador	1.4	5.1
Brazil	1.4	(1.6)
Argentina	(1.1)	(1.4)

RIK (Royalties in Kind) & Other: Includes royalties and other economic rights paid in kind in Colombia for approximately 4,612 bopd and 6,073 bopd in 3Q2025 and 3Q2024, respectively. No royalties were paid in kind in Ecuador or Brazil. Production in Ecuador is reported before the Government’s production share.

b)	Conversion rate of $mcf/$boe=1/6.

c)	Operating costs per boe included in this table include certain adjustments to the reported figures (IFRS 16 and others).

d)	Reported in the Corporate business segment.

e)	Includes amounts recorded in the Corporate business segment.

Operating costs of sold volumes in Colombia are affected by the mix of royalties and economic rights paid in kind versus paid in cash. Operating cost per sold boe is calculated as total operating costs (including the cost to produce barrels that are used to pay royalties and economic rights in kind) divided by barrels delivered to GeoPark’s offtakers (after royalties and economic rights paid in kind).

Depreciation: Consolidated depreciation charges amounted to $28.7 million in 3Q2025, compared to $33.1 million in 3Q2024.

Write-off of unsuccessful exploration efforts: The consolidated write-off of unsuccessful exploration efforts amounted to $7.5 million in 3Q2025, compared to $11.2 million in 3Q2024. Amounts recorded in 3Q2025 correspond to exploration costs incurred in prior years in the Putumayo Basin in Colombia.

³	For reconciliations, see “Reconciliation of Adjusted EBITDA to Profit Before Income Tax” table below.

Other Income (Expenses): Consolidated other expenses amounted to $3.9 million in 3Q2025, compared to $1.5 million expenses in 3Q2024. Amounts recorded in 3Q2025 mainly include termination costs of $3.3 million, as part of the cost efficiency initiatives implemented during the year.

CONSOLIDATED NON-OPERATING RESULTS AND PROFIT

Financial Expenses: Net financial expenses amounted to $11.0 million in 3Q2025, compared to $9.2 million in 3Q2024. Amounts recorded in 3Q2025 include higher interest expenses from the 2030 Notes, partially offset by a $3.0 million gain from the partial repurchase below par value of 2030 Notes.

Foreign Exchange: Net foreign exchange recorded a $1.5 million loss in 3Q2025, compared to a $1.1 million gain in 3Q2024.

Income Tax: Income taxes totaled $4.0 million in 3Q2025, compared to $21.6 million in 3Q2024, mainly resulting from lower taxable income and the effect of fluctuations of the Colombian peso over deferred income taxes.

Net Profit/Loss: Net profit amounted to $15.9 million in 3Q2025, compared to $25.1 million profit in 3Q2024.

BALANCE SHEET

Cash and Cash Equivalents: Cash and cash equivalents totaled $197.0 million as of September 30, 2025, compared to $276.8 million as of December 31, 2024.

This net decrease is explained by the following:

CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION

Non-GAAP Measures: The Company believes Adjusted EBITDA 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 and operating netback per boe may not be comparable to other similarly titled measures of other companies.
