CONSISTENT OPERATIONAL EXECUTION ACROSS THE PORTFOLIO

ACCELERATING IN VACA MUERTA WHILE PRESERVING FINANCIAL STRENGTH

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, 2026 ("Second Quarter" or "2Q2026"). A conference call to discuss these results will be held on August 5, 2026, at 10:00 am (Eastern Daylight Time).

GeoPark continued to execute its strategy during the second quarter of 2026, delivering stable production, higher revenues and resilient cash generation while accelerating development activities in Vaca Muerta, the Company’s largest organic growth program.

SECOND QUARTER 2026 FINANCIAL SUMMARY

Brent prices materially strengthened during the quarter, averaging $96.9/bbl, driven by the continuation of geopolitical disruptions. This higher benchmark environment and narrower Vasconia differentials supported an improvement in GeoPark’s realized pricing, with the Company delivering a combined realized price of $67.2/bbl in 2Q2026¹, compared to $60.4/bbl in 1Q2026.

Production from Colombia and Argentina averaged 27,271 boepd, broadly in line with 1Q2026, while sales volumes² remained stable. As a result, total revenue increased by 12% compared to 1Q2026 to $143.3 million in 2Q2026.

In 2Q2026, GeoPark reported Adjusted EBITDA³ of $73.1 million (51% margin), up 3% from 1Q2026. Solid revenue performance largely offset higher operating costs, which increased to $17.9 per produced barrel in 2Q2026 from $14.7 per produced barrel in 1Q2026, primarily reflecting higher energy costs, increased levels of activity carried out during the quarter, and the appreciation of the Colombian and Argentine currencies⁴.

Operating profit stood at $40.8 million in 2Q2026, compared to $58.0 million in 1Q2026, a quarter that included the non-recurring net break-up fee receivable related to the Frontera Energy transaction that amounted to $14.4 million. Net income for the quarter totaled $14.0 million.

Capital expenditures totaled $76.4 million in 2Q2026, primarily focused on production and development activities across the portfolio, including drilling, completion, workover and strategic infrastructure investments. In Colombia (36% of total capital expenditures), execution was centered on development and infrastructure optimization in the Llanos blocks and continued drilling and infrastructure projects in the CPO-5 Block. In Argentina (64% of total capital expenditures), execution focused on the advancement of drilling, completion and evacuation infrastructure in Vaca Muerta. The Company delivered ROACE of 19%, underscoring disciplined, returns-focused capital allocation.

GeoPark continued to generate solid operating cash flow during the quarter of $108.4 million, supported by operational strength that enabled the Company to fund its investment program and increase its cash position. Cash and cash equivalents stood at $316.3 million as of the end of 2Q2026, compared to $274.9 in 1Q2026.

Net debt stood at $317.8 million at the end of 2Q2026, with a net leverage ratio of 1.2x. In June 2026, GeoPark renewed and extended its senior unsecured contingent credit facility, which is available through December 2028, with final maturity in March 2029, with no drawn amounts to date.

The 2026 hedging program remains unchanged with oil price protection for 2026 secured through three-way collars covering approximately 19,000 bopd of full-year production, with a first floor of $64.8/bbl, a second floor of $50/bbl, and average price ceilings of $72/bbl. For 2027, approximately 19,000 bopd of expected production has been hedged on a full-year basis, with improved protection levels securing an average first floor of $69.7/bbl, a second floor of $50/bbl, and average price ceilings of $78.6/bbl.

The Board declared a quarterly cash dividend of $0.023 per share (approximately $1.5 million), payable on September 2, 2026, to shareholders of record at the close of business on August 19, 2026.

GeoPark’s 2026 Annual General Meeting ("AGM") was held on July 14, 2026. Shareholder participation was broad, with quorum reaching 61.57% of shares entitled to vote. All resolutions submitted for consideration were approved, each with more than 99% of votes cast in favor, reflecting strong shareholder support.

Board of Directors and Committees Update

As part of its ongoing efforts to strengthen corporate governance, improve oversight effectiveness and streamline decision-making, the Board of Directors approved a revised committee structure, reducing the number of standing committees from six to four.

The new structure comprises the Audit Committee, chaired by Robert Bedingfield; the Nomination & Compensation Committee, chaired by Gabriel Gilinski; the Corporate Affairs Committee, chaired by James F. Park; and the Technical Committee, chaired by Brian Maxted.

The revised framework consolidates overlapping responsibilities and clarifies the allocation of key governance, risk, sustainability, compensation and technical oversight matters across the Board and its committees.

Additionally, the Board appointed Mr. James F. Park as the Chair of the Board, and Felipe Bayon, the Company’s Chief Executive Officer, as Vice Chair.

CEO Comment

Felipe Bayon, Chief Executive Officer of GeoPark, said: "Our second quarter results demonstrate the consistency of our execution and the strength of our portfolio. While maintaining stable production and resilient cash generation, we continued to advance the largest investment program in our recent history, reaching important milestones in Argentina ahead of schedule while preserving financial discipline and a strong balance sheet. Colombia continues to provide a robust platform of production and cash flow through disciplined reservoir management and operational excellence. As we move through this peak investment period, we remain focused on executing safely and efficiently, allocating capital with discipline and creating sustainable long-term value for our shareholders".

NOTICE

Additional information about GeoPark can be found in the Invest with Us section of the website at www.geo-park.com.

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.
