GEOPARK REPORTS FIRST QUARTER 2026 RESULTS

STRONG OPERATIONAL PERFORMANCE CONTINUES

STRENGTHENED FINANCIAL CAPACITY AND FLEXIBILITY

Bogota, Colombia – May 6, 2026 - 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 March 31, 2026 (“First Quarter” or “1Q2026”). A conference call to discuss these results will be held on May 7, 2026, at 10:00 am (Eastern Daylight Time).

GeoPark performed strongly in 1Q2026, combining solid operational execution with disciplined financial management. The Company benefited from a constructive pricing environment and effective commercial execution, while maintaining cost efficiency and navigating market volatility through its risk management strategy. During the quarter, GeoPark strengthened its financial and liquidity position, while advancing its strategic priorities, positioning the Company to deliver resilient performance and long-term value creation.

FIRST QUARTER 2026 FINANCIAL SUMMARY

Brent prices materially strengthened during the quarter, averaging $77.9/bbl, driven by geopolitical disruptions. This stronger benchmark environment supported an improvement in GeoPark’s realized pricing, with the Company delivering a combined realized price of $60.4/bbl in 1Q2026, compared to $54.8/bbl in 4Q2025. While the benefit of higher benchmark prices was partially moderated by the Company’s hedging strategy and wider Vasconia differentials during the quarter, GeoPark continued to capture attractive pricing levels through disciplined commercial execution and risk management.

Production from Colombia and Argentina (excluding the divestment of Ecuador and Brazil assets) increased by 1% versus 4Q2025, reinforcing the production inflection achieved in 2025. Sales volumes¹ improved by 8%, including the commercialization of deferred sales volumes produced during 4Q2025.

As a result, total revenue increased by 16% compared to 4Q2025, supported by higher sales volumes and an improved realized price, in line with the Company’s disciplined approach to risk management.

In 1Q2026, GeoPark reported Adjusted EBITDA² of $71.3 million (56% margin), 54% higher than 4Q2025. This was driven by the revenue performance described above, as well as improved operating costs, which decreased to $14.7 per barrel of produced boe from $15.8 per boe in 4Q2025, despite an adverse exchange rate impact in Colombia and Argentina during the quarter.

Building on a strong operating performance, with operating profit increasing to $58.0 million in 1Q2026 from $20.6 million in 4Q2025, net income for the quarter totaled $20.2 million. Reported net income included non-recurring items including the break-up fee receivable related to the transaction with Frontera Energy, net of associated transaction costs and other items. Compared to 4Q2025, net income was also impacted by a higher income tax charge, reflecting higher taxable income and the 10% tax surcharge in Colombia due to higher oil prices.

¹ Sales volumes expressed in barrel of oil equivalent per day.

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

Capital expenditures totaled $22.0 million in 1Q2026, primarily focused on maintaining and enhancing production through an integrated drilling and workover campaign in the Llanos 34 block (GeoPark operated, 45% WI). During the quarter, the Company also conducted drilling operations at the Bisbita Norte-1 well in the Llanos 123 block (GeoPark operated, 50% WI) and continued infrastructure upgrades on the Loma Jarillosa Este platforms, laying a solid foundation for the upcoming drilling campaign in Vaca Muerta. The Company generated Adjusted EBITDA equal to 3.2x its capital expenditures and delivered ROACE of 19%, underscoring disciplined, returns-focused capital allocation.

GeoPark continued to generate solid operating cash flow during the quarter ($32.9 million) supported by operational strength that enabled the Company to fund its investment program. Additional cash inflows during the quarter included $65.0 million in local debt raised to fund the acquisition of Frontera Energy’s E&P assets, $100.3 million from escrow recovery and the break-up fee proceeds related to that transaction, as well as $107.0 million from Grupo Gilinski’s investment in 20% of the company’s shares. As a result, GeoPark’s cash and cash equivalents stood at $274.9 million as of the end of 1Q2026.

Net debt stood at $333.1 million at the end of 1Q2026, with a leverage ratio of 1.3x, reflecting a robust capital structure.

Regarding hedging, the Company continues to proactively monitor market conditions, maintaining a disciplined risk management approach while preserving strong liquidity and financial flexibility. As of the date hereof, oil price protection for 2026 has been secured through three-way collars covering approximately 19,000 bpd of full-year production, with a first floor of $64.8/bbl, a second floor of $50/bbl, and average ceiling prices of $72/bbl. For 2027, approximately 11,000 bpd of expected production has been hedged on a full-year basis, with comparable levels of downside protection and upside participation.

During the quarter, GeoPark announced the entry of Grupo Gilinski as a new strategic investor, representing a meaningful shift in the Company’s shareholder composition. This investment introduces a long-term aligned partner with a proven track record in value creation, further strengthening GeoPark’s strategic positioning. The transaction enhances the Company’s financial flexibility and provides additional capacity to actively pursue value-accretive growth opportunities.

The Board declared a quarterly cash dividend of $0.023 per share, payable on June 4, 2026, to shareholders of record at the close of business on May 20, 2026.

Felipe Bayon, Chief Executive Officer of GeoPark, said: “We delivered a strong start to 2026, with significant growth in revenues and EBITDA supported by solid operational execution, improved pricing and disciplined cost management. During the quarter, we further strengthened our balance sheet, increased liquidity and continued advancing our strategic priorities, including the integration of Vaca Muerta and disciplined capital allocation. In addition, the entry of Grupo Gilinski as a strategic long-term aligned partner marks an important milestone, strengthening our shareholder alignment, financial position and providing additional capacity to pursue value-accretive growth opportunities. We remain well positioned to navigate market volatility while capturing opportunities ahead.”

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, investment program, drilling operations, 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.

Item 2

SUPPLEMENT TO FIRST QUARTER 2026 RESULTS RELEASE

This document should be read in conjunction with GeoPark’s First Quarter 2026 Results Release, available on the Company’s website.

PRODUCTION, DELIVERIES AND REALIZED OIL PRICES

Production: Average net oil and gas production in 1Q2026 was 27,249 boepd, down 6% compared to 1Q2025 mainly due to the natural decline in the core Llanos 34 Block (GeoPark operated, 45% WI), temporary blockades affecting operations in the CPO-5 Block (GeoPark non-operated, 30% WI), and the divestments of the Llanos 32 Block (GeoPark non-operated, 12.5% WI¹) in Colombia, the Perico (GeoPark non-operated, 50% WI) and Espejo (GeoPark operated, 50% WI) Blocks in Ecuador and the Manati gas field (GeoPark non-operated, 10% WI) in Brazil, partially offset by fresh production from the newly acquired Loma Jarillosa Este and Puesto Silva Oeste Blocks (GeoPark operated, 100% WI) in Vaca Muerta, Argentina, and successful results in the Llanos 123 Block (GeoPark operated, 50% WI) in Colombia. Oil represented 99.6% of total reported production both in 1Q2026 and 1Q2025.

For further details, please refer to the 1Q2026 Operational Update published on April 23, 2026.

Deliveries: Oil and gas deliveries to GeoPark’s offtakers in 1Q2026 totaled 23,634 boepd, down by 3% compared to 1Q2025, mainly due to lower production.

Reference and Realized Oil Prices: Brent crude oil prices averaged $77.9/bbl during 1Q2026, and the consolidated realized oil sales price (before earn-out to ex-owners of certain blocks and hedge result) increased by 3% to $67.4/bbl in 1Q2026, compared to 1Q2025.

A breakdown of reference and net realized oil prices in relevant countries in 1Q2026 and 1Q2025 is shown in the tables below:

REVENUE AND COSTS

Revenue: Consolidated revenue decreased by 7% to $128.4 million in 1Q2026, compared to $137.3 million in 1Q2025, mainly reflecting lower realized oil and gas prices and lower deliveries.

Sales of crude oil: Consolidated oil revenue increased by 1% to $138.6 million in 1Q2026, mainly due to a 3% increase in realized oil prices and a 3% decrease in deliveries. Oil revenue was 100% of total revenue in both 1Q2026 and 1Q2025.

The table below provides a breakdown of crude oil revenue in 1Q2026 and 1Q2025:


Oil Revenue (In millions of $)		1Q2026		1Q2025
Colombia		130.6		130.1
Argentina		8.0		—

Oil Revenue		138.6		137.1

Sales of purchased crude oil: No sales of purchased crude oil were recorded in 1Q2026, compared to $0.4 million in 1Q2025. 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 $0.03 million in 1Q2026, compared to zero in 1Q2025.

The table below provides a breakdown of gas revenue in 1Q2026 and 1Q2025:

Commodity Risk Management Contracts: Commodity risk management contracts, which are designated and qualify as cash flow hedges, amounted to a $10.2 million loss in 1Q2026, compared to a $0.2 million loss in 1Q2025.

In 1Q2026, GeoPark had zero cost collars covering 13,000 bopd including purchased puts with an average price of $65.2/bbl and sold calls at an average price of $73.0/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 increased to $37.7 million in 1Q2026 from $35.4 million in 1Q2025, mainly resulting from higher operating costs and higher royalties paid in cash.

The table below provides a breakdown of production and operating costs in 1Q2026 and 1Q2025:


Production and Operating Costs (In millions of $)		1Q2026		1Q2025
Operating costs		(34.0)		(32.9)

Purchased crude oil		—		(0.3)
Share-based payments		(0.1)		(0.2)
Production and Operating Costs		(37.7)		(35.4)

Consolidated operating costs amounted to $34.0 million in 1Q2026, compared to $32.9 million in 1Q2025.

The table below provides the operating cost on a per boe basis in 1Q2026 and 1Q2025:


Operating Costs (Per boe)^a		1Q2026		1Q2025
Operating costs per produced boe		(14.7)		(12.3)
Operating costs per sold boe		(16.4)		(15.6)

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 $2.7 million in 1Q2026, compared to $1.2 million in 1Q2025, mainly resulting from the newly acquired assets in Vaca Muerta, Argentina.

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 $0.9 million in 1Q2026, compared to $0.8 million in 1Q2025.

No consolidated purchased crude oil charges were recorded in 1Q2026, compared to $0.3 million in 1Q2025, 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 $8.8 million in 1Q2026, compared to $2.2 million in 1Q2025. The fluctuation in transportation costs is mainly attributed to deliveries at different sales points in the CPO-5 and Llanos 123 Blocks in Colombia, including the shift to export delivery locations under a new commercial arrangement with British Petroleum 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 increased to $2.8 million in 1Q2026, compared to $2.5 million in 1Q2025.

Administrative Expenses: Consolidated G&A decreased to $7.8 million in 1Q2026 compared to $9.1 million in 1Q2025.

Adjusted EBITDA: Consolidated Adjusted EBITDA² decreased by 19% to $71.3 million in 1Q2026 compared to 1Q2025. On a per boe basis, Adjusted EBITDA decreased to $33.5 per boe in 1Q2026 from $40.2 per boe in 1Q2025.

RIK (Royalties in Kind) & Other: Includes royalties and other economic rights paid in kind in Colombia for approximately 4,157 bopd and 4,869 bopd in 1Q2026 and 1Q2025, respectively. No royalties were paid in kind in Argentina or Ecuador. 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 $26.0 million in 1Q2026, compared to $32.0 million in 1Q2025.

Write-off of unsuccessful exploration efforts: The consolidated write-off of unsuccessful exploration efforts amounted to $1.7 million in 1Q2026, compared to $5.9 million in 1Q2025.

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.
