[6-K] GeoPark Ltd Current Report (Foreign Issuer)

Rhea-AI Filing Summary

GeoPark Limited (GPRK) filed interim results showing lower activity but continued profitability. For the three months ended September 30, 2025, revenue was $125.1 million with profit of $15.9 million and basic EPS of $0.31 (diluted $0.30). For the nine-month period, revenue was $382.2 million, Adjusted EBITDA $230.9 million, and profit $18.6 million, reflecting softer oil pricing and volumes, higher financial expenses, and an earlier impairment tied to Ecuador asset sales.

GeoPark ended the quarter with cash of $197.0 million and total borrowings of $570.4 million. In January, it issued $550.0 million notes due 2030 at 8.75% and used proceeds to repurchase 2027 notes and repay up to $152.0 million under a prepayment facility. From June–September, it repurchased $77.4 million face of the 2030 notes at ~$0.89, recognizing $8.0 million of financial income, and continued repurchases in October.

Strategically, the company agreed to acquire assets in Argentina’s Vaca Muerta for $115.0 million (closed October 16, 2025) and moved to divest interests in Ecuador (impairment $31.0 million recognized) and certain non-core assets in Colombia and Brazil. It paid three $0.147/share quarterly dividends in 2025 and later approved a revised program totaling about $6.0 million over the next four quarters, followed by a planned suspension starting with Q3 2026 results. The Board rejected a $9.00 per share cash proposal from Parex Resources Inc.

Insights

Energy credit & cash flow analyst

Lower revenue and higher financing costs, offset by refinancing and asset reshaping.

GeoPark reported nine-month revenue of $382.2M and Adjusted EBITDA of $230.9M, down year over year as oil pricing and volumes softened. Operating profit for 9M was $89.9M, with a high effective tax rate (56%) weighing on net income of $18.6M. Q3 profit was $15.9M.

On capital structure, the company issued $550M notes due 2030 at 8.75% and used proceeds to retire 2027 notes and repay prepayments. It then repurchased $77.4M face of the 2030s at discounts, booking $8.0M in gains. Year-end position shows cash of $197.0M and borrowings of $570.4M.

Portfolio moves include a $115.0M Vaca Muerta acquisition (closed Oct 16, 2025) and pending sales in Ecuador, where an impairment of $31.0M was recognized. Dividend actions include three $0.147 per share payments and a later program of about $6.0M over the next four quarters, followed by a planned suspension starting with Q3 2026 results. Actual impact will depend on commodity prices, execution of divestments, and hedging outcomes disclosed for 2025–2026.

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 November 4, 2025.

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, 2024, 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, 2024, that apply for the first time in 2025, 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, 2024.

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, 2024.

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.

The Group maintained a cash position of US$ 197,007,000 as of September 30, 2025. In addition, GeoPark has access to a US$ 100,000,000 senior unsecured credit agreement with Banco BTG Pactual S.A. and Banco Latinoamericano de Comercio Exterior S.A., and US$ 147,182,000 in uncommitted credit lines. Additionally, GeoPark Argentina S.A., the Group’s Argentinian subsidiary, holds approval from the Argentinian securities regulator to issue up to US$ 500,000,000 in debt securities. After the balance sheet date, in October 2025, GeoPark obtained access to an up to US$ 50,000,000 prepayment facility from BP Products North America Inc (“BP”).

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.

Risk management contracts

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 protect 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 in Other Reserve within Equity. The gain or loss relating to the ineffective portion, if any, is 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 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 nine-month period ended September 30, 2025, and for the following periods as a consequence of the derivative contracts in force as of September 30, 2025:

Currency risk management contracts

From time to time, the Group enters into derivative financial instruments in order to anticipate currency fluctuations in Colombia.

In November 2024, GeoPark entered into derivative financial instruments (zero-premium collars) with a local bank in Colombia, in order to hedge against potential currency fluctuations related to income tax payments scheduled for May and June 2025.Additionally, in April 2025, GeoPark entered into derivative financial instruments (zero-premium collars) with local banks in Colombia to mitigate potential currency fluctuations and protect the Group’s exposure to the Colombian peso arising from its regular business operations.

Energy cost risk management contracts

In July 2025, GeoPark entered into a derivative financial instrument to manage its exposure to energy cost volatility in Colombia, particularly in the Llanos 34 Block, where electricity expenses represent a significant portion of its production and operating costs. This derivative is a Contract for Differences (“CfD”) on the generation component of the electricity tariff and is structured as a fixed-for-floating swap that settles financially against the wholesale spot market price. It is effective from August to December 2025, covering 12.5 MW (approximately 9 GWh/month) at a strike price of COP 312/kWh from August 2025 to September 2025 and COP 350/kWh from October 2025 to December 2025, indexed to the monthly Producer Price Index.

The Group’s CfD is designated and qualifies as a cash flow hedge. The effective portion of changes in the fair value of this derivative is recognized in Other Reserve within Equity. The gain or loss relating to the ineffective portion, if any, is recognized immediately as a gain or loss in the results of the periods in which it occurs. 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, as part of the Production and operating costs line item in the Condensed Consolidated Statement of Income (see Note 5).

(a) 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.

(b) Includes the Special Tax for Catatumbo in Colombia, effective from February 2025, which imposes a 1% tax rate on the sale price (domestic) or FOB value (exports) of crude oil and coal at the time of their first sale or export. The charge amounted to US$ 2,490,000 for the nine-month period ended September 30, 2025 (US$ 1,337,000 for the three-month period ended September 30, 2025).

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	​	Nine-month	​	Nine-month
​	​	period ended	​	period ended	​	period ended	​	period ended
​	​	September 30,	​	September 30,	​	September 30,	​	September 30,
Amounts in US$ ´000	​	2025	​	2024	​	2025	​	2024
Current income tax expense		(10,691)	​	(23,063)	​	(44,089)	​	(103,625)
Deferred income tax benefit (expense)	​	6,703	​	1,513	​	20,062	​	(24,560)
​	​	(3,988)		(21,550)	​	(24,027)	​	(128,185)

The Group’s consolidated effective tax rate was 20% and 46% for the three-month periods ended September 30, 2025 and 2024, respectively, and 56% and 61% for the nine-month periods ended September 30, 2025 and 2024, respectively.

As of September 30, 2025 and 2024, 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 0% for 2025, and therefore, the applicable statutory income tax rate in Colombia for 2025 would be 35%.

The Group’s consolidated effective tax rate of 20% for the three-month period ended September 30, 2025, which is lower than the applicable statutory income tax rate in Colombia, is mainly driven by the effect of the revaluation of the Colombian peso on deferred income taxes.

Cash distributions

In March, May and August 2025, the Company’s Board of Directors declared cash dividends of US$ 0.147 per share which were paid on March 31, June 5 and September 4, 2025, respectively.

After the balance sheet date, in October 2025, GeoPark announced that its Board of Directors approved a revised dividend program totaling approximately US$ 6,000,000 over the next four quarters, followed by a dividend suspension starting with the third quarter 2026 results.

Equity (Continued)

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 in Other Reserve 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 nine-month period ended September 30, 2025, a realized gain of US$ 6,138,000 on commodity risk management contracts and a realized loss of US$ 166,000 on energy cost risk management contracts were reclassified to the Condensed Consolidated Statement of Income.

(a) Fully repaid in July 2025.

On January 31, 2025, the Company successfully placed an aggregate principal amount of US$ 550,000,000 senior notes (the “Notes due 2030”) which were offered in a private placement to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non U.S. persons in accordance with Regulation S under the Securities Act. The Notes due 2030 are fully and unconditionally guaranteed jointly and severally by GeoPark Colombia S.L.U., GeoPark Colombia S.A.S., and GeoPark Argentina S.A. The Notes due 2030 were priced at 100% and carry a coupon of 8.75% per annum (yield 8.75% per annum). The debt issuance cost for this transaction amounted to US$ 5,034,000 (debt issuance effective rate: 8.98%). Final maturity of the Notes due 2030 will be January 31, 2030.

Table of Contents

Note 14 (Continued)

Borrowings (Continued)

The indenture governing the Notes due 2030 includes incurrence test covenants that provide among other things, that, the Net Debt to Adjusted EBITDA ratio should not exceed 3.5 times and the Adjusted EBITDA to Interest ratio should exceed 2.5 times. Failure to comply with the incurrence test covenants does not trigger an event of default. However, this situation may limit the Company’s capacity to incur additional indebtedness, as specified in the indenture governing the Notes due 2030. Incurrence covenants as opposed to maintenance covenants must be tested by the Company before incurring additional debt or performing certain corporate actions including but not limited to dividend payments, restricted payments and others.

The net proceeds from the Notes due 2030 were used by the Company to repurchase part of its Notes due 2027 for a nominal amount of US$ 405,333,000 through a concurrent tender offer, to repay up to US$ 152,000,000 of outstanding prepayments due under an offtake and prepayment agreement with Vitol (see Notes 29 and 30 to the annual consolidated financial statements as of and for the year ended December 31, 2024) and, the remainder for general corporate purposes, including capital expenditures.

From June to September 2025, the Company repurchased through open market transactions and cancelled with the Trustee, a total nominal amount of US$ 77,405,000 of its Notes due 2030 at an average price of US$ 0.89. The difference of US$ 7,969,000 between the carrying amount of the debt repurchased (net of the associated unamortized issuance costs) and the consideration paid was recognized as financial income in the condensed consolidated statement of income. After the balance sheet date, during October 2025, the Company continued repurchasing its Notes due 2030 for a nominal amount of US$ 30,916,000 at an average price of US$ 0.92.

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 September 30, 2025.

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 91% of its carrying amount, including interest accrued as of September 30, 2025. Fair value was calculated based on market price for the Notes and is within Level 1 of the fair value hierarchy.

Business transactions

19.1 Recent Acquisition in Argentina’s Vaca Muerta Formation

On September 25, 2025, GeoPark announced that it had entered into an agreement to acquire a 100% operated working interest (“WI”) in the Loma Jarillosa Este and Puesto Silva Oeste Blocks located in the Neuquen Province, Argentina, targeting black oil in the Vaca Muerta formation. The transaction is consistent with GeoPark’s strategic intent to establish a position in Vaca Muerta, one of the world’s most prolific unconventional oil and gas plays.

Concurrently, GeoPark and the Government of Neuquen Province signed two “Actas Acuerdo” (Deeds of Agreement), which establish the parties’ commitment to the deal and outline the terms and conditions under which the concessions would be transferred. The Deeds of Agreement include the issuance of a new unconventional exploitation license for the Puesto Silva Oeste Block that requires GeoPark to transfer a 5% WI to the provincial state-owned company, Gas y Petróleo del Neuquén S.A. (“GyP”), therefore resulting in a 95% operated WI in that block. GeoPark will carry GyP’s portion of the capital and expenditure on a fully recoverable basis with up to 100% of GyP’s share of production.

The agreement established a consideration paid of US$ 115,000,000 in cash, subject to an interim period adjustment related to the net cash flows from operations since January 1, 2025 (the effective date of the acquisition). As of September 30, 2025, GeoPark granted a security deposit of US$ 22,700,000, which was recognized in the “Prepayments and other receivables” line item within “Current assets” in the interim condensed consolidated statement of financial position. Subsequently, the transaction closed on October 16, 2025, upon which GeoPark acquired control of the assets and paid the remaining US$ 92,300,000 of the consideration paid.

In accordance with the acquisition method of accounting, the acquisition cost will be allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. The excess of acquisition cost, if any, over the net identifiable assets acquired represents goodwill.

The preliminary purchase price allocation is incomplete as of the date of issuance of these interim condensed consolidated financial statements since the valuation process is ongoing. Estimated acquisition-related transaction costs amounted to approximately US$ 310,000 and were expensed as incurred.

As part of this transaction, GeoPark assumed the following firm investment commitments:

● Loma Jarillosa Este: Well interventions and facilities enhancements for approximately US$ 4,800,000 by December 2025.

● Puesto Silva Oeste: Drilling, completion and put into production of one horizontal well for approximately US$ 14,500,000 by October 2028.

19.2 Divestment of working interests in Ecuador

During the first quarter of 2025, the Company’s Board of Directors approved the decision to evaluate strategic options for its assets in Ecuador. As a result, during the second quarter of 2025, GeoPark and its partner accepted an offer to divest their respective 50% working interests in the Perico and Espejo Blocks.

Subsequently, on July 31, 2025, the parties executed definitive Asset Purchase Agreements for a total consideration of US$ 6,910,000, corresponding to GeoPark’s working interest. This amount includes a firm purchase price of US$ 7,775,000, net of a working capital adjustment of US$ 865,000, and is subject to customary interim period adjustments. In addition, the agreement includes a contingent consideration of US$ 750,000, payable upon the Perico Block achieving cumulative gross production of two million barrels as from January 1, 2025. The closing of the transaction remains subject to the approval of the field development plans by the Ministry of Energy and Mines and other customary regulatory authorizations.

19.2 Divestment of working interests in Ecuador (Continued)

Since June 2025, the amount of Property, plant and equipment and Right-of-use assets corresponding to the Perico and Espejo Blocks and the liabilities associated to them have been classified as held for sale. Immediately prior to this reclassification, the recoverable amount of the associated net assets was estimated, and an impairment loss of US$ 30,989,000 was recognized in the Condensed Consolidated Statement of Income.

19.3 Divestment of non-operated working interest in the Llanos 32 Block in Colombia

On March 14, 2025, GeoPark agreed to transfer, subject to regulatory approval, its non-operated working interest in the Llanos 32 Block in Colombia to its joint operation partner for a total consideration of US$ 19,000,000, minus working capital adjustment of US$ 3,660,000. GeoPark has already received the net proceeds from the transaction. On October 27, 2025, the ANH approved the transfer and instructed that the amendment to the E&P Contract be executed to formalize the assignment to the former joint operation partner.

19.4 Divestment of non-operated working interest in the Manati gas field in Brazil

On March 27, 2025, GeoPark entered into an agreement to sell its 10% non-operated working interest in the Manati gas field in Brazil for a total consideration of US$ 1,000,000, subject to working capital adjustment, plus a contingent payment of an additional US$ 1,000,000, subject to the field’s future cash flow or its potential conversion into a natural gas storage facility. As of the date of these interim condensed consolidated financial statements, GeoPark has collected an advance payment of US$ 500,000. Closing of the transaction is pending customary regulatory approvals.

Since March 2025, the amount of Property, plant and equipment and Right-of-use assets corresponding to the Manati gas field and the liabilities associated to it have been classified as held for sale.

19.5 Unconsummated transaction in Argentina

On May 13, 2024, GeoPark announced the execution of a farm-out agreement with PGR, a subsidiary of Mercuria Energy Trading (“Mercuria”), for the acquisition of non-operated working interests in four adjacent unconventional blocks in the Neuquén Basin, Argentina. However, on May 14, 2025, GeoPark announced that PGR exercised its contractual right to withdraw from the transaction. As a result, the transaction was not completed.

Accordingly, GeoPark was not required to pay the remaining balance of the upfront consideration, and all advance payments previously made were fully reimbursed. The advance payments included US$ 49,096,000 paid in May 2024, comprising US$ 38,000,000 related to the upfront consideration and US$ 11,096,000 related to the acquisition of midstream capacity, and US$ 4,988,000 paid in December 2024 for additional midstream capacity. These amounts had been recognized under the “Prepayments and other receivables” line item within “Current assets” in the Consolidated Statement of Financial Position as of December 31, 2024, and were fully collected in May 2025.

Note 20

Impairment test on Property, plant and equipment

The Group’s management considers each of the blocks or group of blocks in which the Group has working or economic interests as cash-generating unit (“CGU”). The blocks with no material investment on property, plant and equipment or with operations that are not linked to oil and gas prices were not subject to impairment test.

As of June 30, 2025, the divestment process of the Perico and Espejo Blocks in Ecuador, described in Note 19.2, was considered an indicator of impairment. The carrying amount of the net assets associated with these blocks exceeded their fair value less cost of disposal. Accordingly, the net assets were written down to their known selling price, resulting in the recognition of an impairment loss of US$ 30,989,000, comprising US$ 18,111,000 related to oil and gas properties and US$ 12,878,000 related to exploration and evaluation assets.

Additionally, beginning in early April 2025, international crude oil prices experienced a significant decline, driven by a combination of geopolitical tensions and macroeconomic concerns. As of March 31, 2025, the Brent crude oil price was approximately US$ 74 per barrel. However, during the first week of April, Brent fell by more than 20%, reaching levels below US$ 60 per barrel, the lowest level since mid-2021. This abrupt downturn was primarily triggered by escalating trade tensions between the United States and major global trading partners, notably China, following the U.S. administration’s announcement of increased import tariffs. These actions intensified concerns about a potential global economic slowdown, thereby weakening the outlook for oil demand. Concurrently, certain OPEC+ members unexpectedly increased production in early April, further exacerbating the downward pressure on international crude oil benchmarks. Throughout the second quarter of 2025, this oil price volatility persisted. Although Brent prices temporarily recovered in mid-June, driven by increased geopolitical tensions in the Middle East, particularly the conflict between Israel and Iran, reaching levels above US$ 74 per barrel, they declined again by quarter-end, closing around US$ 68 per barrel as of June 30, 2025.

As these levels fell below the base case price assumptions used in the impairment tests performed as of December 31, 2024, GeoPark identified the existence of impairment indicators in the Llanos 87, CPO-5 and Platanillo Blocks in Colombia in accordance with IAS 36, which prompted the Group to perform updated impairment assessments as of June 30, 2025. As a result of the test performed, no impairment losses were recognized, except for the abovementioned impairment charge in the Perico and Espejo Blocks in Ecuador. The recoverable amounts of the other CGUs tested continue to exceed their respective carrying values, even under more conservative pricing scenarios.

As of September 30, 2025, no additional indicators of impairment were identified. GeoPark will continue to closely monitor macroeconomic developments and oil market conditions and will revise its estimates in future periods if warranted by changes in circumstances.

Note 21

Cost efficiency measures

From March to September 2025, the Group implemented cost efficiency measures which included the immediate reduction of the workforce. These measures were undertaken to enhance cost efficiency and better align the organizational structure with the Group’s strategic objectives and operational challenges. In connection with these measures, the Group incurred termination costs of US$ 6,945,000.

Subsequent events

Rejection of unsolicited proposal from Parex Resources Inc.

On October 29, 2025, GeoPark confirmed that its Board of Directors had reviewed and unanimously rejected an unsolicited, non-binding proposal from Parex Resources Inc. (“Parex”) to acquire the Company in an all-cash transaction for US$ 9.00 per share. The proposal, originally submitted on September 4, 2025, prior to the announcement of GeoPark’s acquisition in Vaca Muerta (see Note 19.1), was deemed by the Board to significantly undervalue the Company and not to be in the best interests of GeoPark or its shareholders.
