EXPLANATORY NOTES TO THE INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1

General information

GeoPark Limited (the “Company”) is a company incorporated under the laws of Bermuda. The registered office address is Clarendon House, 2 Church Street, Hamilton HM11, Bermuda.

The principal activity of the Company and its subsidiaries (the “Group” or “GeoPark”) is the exploration, development and production for oil and gas reserves in Latin America.

These interim condensed consolidated financial statements were authorized for issue by the Board of Directors on August 3, 2026.

Basis of Preparation

The interim condensed consolidated financial statements of GeoPark Limited are presented in accordance with IAS 34 “Interim Financial Reporting”. They do not include all of the information required for full annual financial statements and should be read in conjunction with the annual consolidated financial statements as of and for the year ended December 31, 2025, which have been prepared in accordance with IFRS.

The interim condensed consolidated financial statements have been prepared in accordance with the accounting policies applied in the most recent annual consolidated financial statements. The Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective. The amendments and interpretations detailed in the annual consolidated financial statements as of and for the year ended December 31, 2025, that apply for the first time in 2026, do not have an impact on the interim condensed consolidated financial statements of the Group.

Whenever necessary, certain comparative amounts have been reclassified to conform to changes in presentation in the current period.

Taxes on income in the interim periods are accrued using the tax rate that would be applicable to expected total annual profit or loss.

The activities of the Group are not subject to significant seasonal changes.

Estimates

The preparation of interim financial information requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Group’s accounting policies. Actual results may differ from these estimates.

In preparing these interim condensed consolidated financial statements, the significant judgements made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the annual consolidated financial statements as of and for the year ended December 31, 2025.

Financial risk management

The Group’s activities expose it to a variety of financial risks: currency risk, price risk, credit risk concentration, funding and liquidity risk, interest risk and capital risk. The interim condensed consolidated financial statements do not include all the financial risk management information and disclosures required in the annual consolidated financial statements and should be read in conjunction with the Group’s annual consolidated financial statements as of and for the year ended December 31, 2025.

Table of Contents

Note 1 (Continued)

Financial risk management (Continued)

The Group is continually reviewing its exposure to the current market conditions and adjusting its capital expenditures program which remains flexible and quickly adaptable to different oil price scenarios. GeoPark also continues to add new oil hedges, increasing its price risk protection within the upcoming fifteen months.

As of June 30, 2026, the Group maintained a cash position of US$ 316,259,000, had access to up to US$ 280,000,000 of committed prepayment facilities with Vitol C.I. Colombia S.A.S. (“Vitol”), a US$ 95,000,000 senior unsecured credit agreement with Banco BTG Pactual S.A. and Banco Latinoamericano de Comercio Exterior S.A., and US$ 170,550,000 in uncommitted credit lines (including US$ 72,500,000 in Argentina). Additionally, GeoPark Argentina S.A., the Group’s Argentine subsidiary, has approval from the Argentine securities regulator to issue up to US$ 500,000,000 in debt securities and, in February 2026, entered into an unsecured committed credit facility with Banco Galicia y Buenos Aires S.A. for up to US$ 38,000,000.

Subsidiary undertakings

The following chart illustrates the main companies of the Group structure as of June 30, 2026:

Details of the subsidiaries and joint operations of the Group are set out in Note 19 to the annual consolidated financial statements as of and for the year ended December 31, 2025.

Note 2

Segment information

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Executive Committee. This committee is integrated by the Chief Executive Officer, Chief Financial Officer, Chief Exploration and Development Officer, Chief Operating Officer and Chief People Officer. This committee reviews the Group’s internal reporting to assess performance and allocate resources. Management has determined the operating segments based on these reports. The committee considers the business from a geographic perspective.

The Executive Committee assesses the performance of the operating segments based on a measure of Adjusted EBITDA. Adjusted EBITDA is defined as profit (loss) for the period (determined as if IFRS 16 Leases has not been adopted), before net finance results, income tax, depreciation, amortization, certain non-cash items such as impairments and write-offs of unsuccessful exploration efforts, accrual of share-based payment, unrealized result on commodity risk management contracts, geological and geophysical expenses allocated to capitalized projects, and other non-recurring events. Other information provided to the Executive Committee is measured in a manner consistent with that in the consolidated financial statements.

Note 4

Commodity risk management contracts

The Group has entered into derivative financial instruments to manage its exposure to oil price risk. These derivatives are zero-premium collars and zero-premium 3 ways (put spread plus call) and were placed with major financial institutions and commodity traders. The Group entered into the derivatives under ISDA Master Agreements and Credit Support Annexes, which provide credit lines for collateral posting, thus alleviating possible liquidity needs under the instruments and protecting the Group from potential non-performance risk by its counterparties.

The Group’s derivatives are designated and qualify as cash flow hedges. The effective portion of changes in the fair values of these derivative contracts are recognized under Other Reserves within Equity. The gains or losses relating to the ineffective portion, if any, are recognized immediately as gains or losses in the results of the periods in which they occur. The amount accumulated in Other Reserves is reclassified to profit or loss as a reclassification adjustment in the same period or periods during which the hedged cash flows affect profit or loss, and are included as part of the Revenue line item in the Condensed Consolidated Statement of Income (see Note 3).

The following table summarizes the Group’s production hedged during the six-month period ended June 30, 2026, and for the following periods as a consequence of the derivative contracts in force as of June 30, 2026:

As of June 30, 2026, the Group had a derivative liability of US$ 20,212,000 related to commodity risk management contracts (see Note 17). This balance includes US$ 6,486,000 of amounts realized in June and settled in cash in July 2026, with the remaining US$ 13,726,000 corresponding to the unrealized mark-to-market valuation of outstanding positions as of period end, primarily driven by the increase in the forward oil price curve (see Note 20).

(a)

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 commercial arrangement with BP Products North America Inc. from August 2025 to April 2026. 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.

Note 10

Income tax

The Group calculates income tax expense using the tax rate that would be applicable to the expected total annual earnings. The main components of income tax expense in the Condensed Consolidated Statement of Income are:


	Three-month	Three-month	Six-month	Six-month
	period ended	period ended	period ended	period ended
Amounts in US$ ´000	June 30, 2026	June 30, 2025	June 30, 2026	June 30, 2025
Current income tax expense	(9,808)	(5,414)	(27,267)	(33,398)
Deferred income tax benefit (expense)	408	(2,178)	(3,448)	13,359
	(9,400)	(7,592)	(30,715)	(20,039)

The Group’s consolidated effective tax rate was 40% and -277% for the three-month periods ended June 30, 2026 and 2025, respectively, and 47% and 88% for the six-month periods ended June 30, 2026 and 2025, respectively.

As of June 30, 2026 and 2025, the statutory income tax rate in Colombia was 35%, though a tax surcharge is also applicable, impacting companies engaged in the extraction of crude oil like GeoPark. The tax surcharge varies from zero to 15%, depending on different Brent oil prices. The Group currently estimates a tax surcharge of 10% for 2026, and therefore, the applicable statutory income tax rate in Colombia for 2026 would be 45%.

Note 10 (Continued)

Income tax (Continued)

The Group’s consolidated effective tax rate of 40% for the three-month period ended June 30, 2026, which is lower than the applicable statutory income tax rate in Colombia, is mainly driven by the effect of fluctuations of the Colombian peso on deferred income taxes (the Colombian peso revalued by 6% during the three-month period ended June 30, 2026).

Equity (Continued)

Strategic equity investment by Grupo Gilinski

On March 5, 2026, GeoPark Limited entered into a share purchase agreement (the “SPA”) with Colden Investments S.A. (“Colden”), an affiliate of Jaime Gilinski, who leads Grupo Gilinski. Under the SPA, Colden invested US$ 107,000,000 to acquire 12,876,053 newly issued common shares of the Company at a price of US$ 8.31 per share. Following the closing of the transaction, Colden held approximately 20% of the Company’s outstanding common shares and became the Company’s largest shareholder.

Pursuant to the SPA, Colden is entitled to nominate two directors to the Company’s nine-member Board of Directors at that ownership level, subject to applicable corporate governance procedures and NYSE requirements. In addition, the SPA includes, among other provisions, an eighteen-month lock-up commitment, certain approval rights while maintaining a minimum 15% ownership stake, and ownership limitations requiring Board approval for increases above 32% during the first twelve months. Gabriel Gilinski was appointed to fill a vacancy on the Board.

During March 2026, Colden and Spaldy Investments Limited, both controlled by Jaime Gilinski, increased their ownership through open market purchases and, as of March 31, 2026, held approximately 25.8% of the Company’s outstanding common shares. In April 2026, their combined ownership further increased to approximately 28%. Under the SPA, upon reaching 28% or more of the Company’s outstanding common shares, Colden becomes entitled to nominate up to three directors to the Company’s nine-member Board, subject to customary corporate governance procedures, applicable law and NYSE requirements. If entitled to nominate three directors, at least one of the Colden nominees must qualify as an independent director under applicable standards. In April 2026, Colden exercised these nomination rights by nominating Gabriel Gilinski, Dorita Gilinski and Camilo Martínez (collectively, the "Colden Nominees") in accordance with the terms of the SPA and the Company's Corporate Governance Guidelines. At the Company's Annual General Meeting (“AGM”) held in July 2026, the Colden Nominees were duly elected as directors to serve until the next AGM of the Company.

Cash distributions

In February and May 2026, the Company’s Board of Directors declared cash dividends of US$ 0.03 and US$ 0.023 per share, which were paid on March 31, 2026 and June 4, 2026 respectively.

Other reserves

GeoPark applies hedge accounting for the derivative financial instruments entered to manage its exposure to oil price risk. Consequently, the Group’s derivatives are designated and qualify as cash flow hedges and, therefore, the effective portion of changes in the fair values of these derivative contracts and the income tax relating to those results are recognized under Other Reserves within Equity. The amount accumulated in Other Reserves is reclassified to profit or loss as a reclassification adjustment in the same period or periods during which the hedged cash flows affect profit or loss. During the six-month period ended June 30, 2026, a realized loss of US$ 51,404,000 on commodity risk management contracts was reclassified to the Condensed Consolidated Statement of Income.

(a)	Includes local borrowings in Colombia and Argentina as described below.

In December 2025, GeoPark Colombia S.A.S. executed a loan agreement with Bancolombia Panamá, S.A. for an amount of US$ 3,000,000 to finance sustainable capital requirements associated with the Orinoquia Regenera project in Colombia. The loan carries a variable interest rate of SOFR risk-free rate plus a margin of 1.8% per annum and matures on December 20, 2029. Principal is repayable semi-annually in equal installments following a grace period of two years, and interest is payable semi-annually on the outstanding balance.

In January 2026, GeoPark Colombia S.A.S. obtained two short-term loans from Bancolombia Panamá, S.A. totaling US$ 25,000,000 (US$ 17,000,000 and US$ 8,000,000) to fund the advance payment related to the unconsummated acquisition of Frontera Energy’s E&P assets in Colombia (see Note 19). The loans were disbursed on January 23, 2026. In February 2026, the terms of these loans were amended, and the loans were restructured to bear interest at a fixed annual rate of 5.06320% and to mature on February 3, 2027.

In February 2026, GeoPark Colombia S.A.S. obtained a short-term loan from Citibank Colombia S.A. for an aggregate principal amount of Colombian Pesos 145,280,000,000 (equivalent to US$ 40,000,000) to support liquidity and working capital requirements in Colombia following the advance payment related to the unconsummated acquisition of Frontera Energy’s E&P assets in Colombia (see Note 19). The loan was disbursed on February 6, 2026, bears interest at a floating rate of IBR (the Colombian interbank reference rate) plus 1.53% per annum, and matures on February 3, 2027. In connection with this borrowing, the Group entered into a cross-currency swap arrangement with Citibank N.A., New York to hedge the foreign exchange exposure associated with the loan and to secure the Colombian peso cash flows required to service principal and interest payments.

In June 2026, GeoPark Argentina S.A. obtained two short-term loans from Banco de Galicia y Buenos Aires S.A. totaling US$ 12,000,000 (equivalent to an aggregate amount of Argentine Pesos 17,332,500,000 at the respective disbursement dates) to finance working capital requirements. After the balance sheet date, in July 2026, GeoPark Argentina S.A. obtained two additional short-term loans from Banco de Galicia y Buenos Aires S.A. and Banco Supervielle S.A., respectively, totaling US$ 15,000,000 (equivalent to Argentine Pesos 22,222,000,000 at the respective disbursement dates), also to finance working capital requirements.

Note 17 (Continued)

Fair value measurement of financial instruments (Continued)

Fair value hierarchy (Continued)

There were no transfers between Level 2 and 3 during the period. The Group did not measure any financial assets or financial liabilities at fair value on a non-recurring basis as of June 30, 2026.

Fair values of other financial instruments (unrecognized)

The Group also has a number of financial instruments which are not measured at fair value in the balance sheet. For the majority of these instruments, the fair values are not materially different to their carrying amounts, since the interest receivable/payable is either close to current market rates or the instruments are short-term in nature.

Borrowings are comprised of fixed rate debt and are measured at their amortized cost. The Group estimates that the fair value of its financial liabilities is approximately 97% of its carrying amount, including interest accrued as of June 30, 2026. Fair value was calculated based on market price for the Notes and is within Level 1 of the fair value hierarchy.

Business transactions

Proposed acquisition of Frontera Energy’s Colombian E&P assets (not consummated)

On January 29, 2026, GeoPark entered into an agreement with Frontera Energy Corporation (“Frontera”) to acquire 100% of Frontera Petroleum International Holdings B.V. (“Frontera International”), which consisted exclusively of oil and gas exploration and production assets in Colombia. On February 2, 2026, GeoPark paid an initial deposit of US$ 75,000,000, with the remaining balance payable at closing, subject to regulatory approvals and customary closing conditions.

On March 5, 2026, Frontera announced that its board of directors had determined that a binding offer from Parex Resources Inc. to acquire the Frontera E&P Assets constituted a “Superior Proposal” under the arrangement agreement with GeoPark, and that the five-business-day matching period had commenced.

Following such notification and after evaluating its match right, on March 9, 2026, GeoPark announced its decision not to raise its offer. As a result, on March 11, 2026, GeoPark received a US$ 25,000,000 break-up fee, which was recognized as a gain within the ‘Other income (expenses), net’ line item in the Condensed Consolidated Statement of Income. On March 13, 2026, the escrow deposit of US$ 75,000,000 was returned together with accrued interest of US$ 258,000.

Note 20

Oil price volatility

During the second quarter of 2026, crude oil markets experienced high price volatility driven primarily by geopolitical developments in the Middle East and the resulting uncertainty over global oil supply and shipping routes through the Strait of Hormuz. Brent crude prices, which were approximately US$ 60 per barrel at the beginning of the year, remained at elevated levels throughout most of the quarter, averaging approximately US$ 97 per barrel, reaching a peak of approximately US$ 118 per barrel, before declining to approximately US$ 73 per barrel by the end of June 2026 following the announcement of a Memorandum of Understanding between the United States and Iran and improving expectations regarding the normalization of regional oil exports.

While the higher oil price environment increased the Group's revenues, the overall financial impact was partially offset by the effects of existing commodity hedging arrangements and price-linked contractual and fiscal mechanisms. Higher crude prices increased royalties, contractual price-sharing mechanisms and tax surcharges, while realized prices were partially limited by hedge ceilings. The extent to which these factors may continue to affect future results will depend on commodity prices, geopolitical developments and market conditions.

Subsequent to June 30, 2026, Brent crude prices remained volatile, trading between approximately US$ 71 and US$ 100 per barrel during July and averaging approximately US$ 82 per barrel by the end of month. These fluctuations continued to be driven by geopolitical developments in the Middle East, including renewed tensions between the United States and Iran and disruptions affecting shipping through the Strait of Hormuz.
