GEOPARK LIMITED PRICES OFFERING OF

U.S.$550,000,000 9.500% SENIOR NOTES DUE 2033

Bogotá, Colombia, October 21, 2026 – GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), an exempted company incorporated under the laws of Bermuda, today announced the pricing of U.S.$550,000,000 aggregate principal amount of 9.500% senior notes due 2033 (the “Notes”). The Notes 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 will be fully and unconditionally guaranteed jointly and severally by GeoPark Colombia S.L.U., GeoPark Colombia S.A.S., and GeoPark Argentina S.A. The settlement of the Notes offering is expected to take place on October 28, 2026, subject to customary closing conditions.

The net proceeds from the Notes offering will be used by the Company to repurchase the Company’s outstanding 8.750% senior notes due 2030 (the “2030 Notes”) through a concurrent tender offer, to repay or redeem, in whole or in part, certain of its existing indebtedness, including the Company’s outstanding 5.500% senior notes due 2027, to fund capital expenditures related to the development of its Vaca Muerta assets over the next 18 months, and for general corporate purposes.

This press release does not constitute an offer to sell or a solicitation of an offer to buy these securities, nor will there be any sale of these securities, in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any state or jurisdiction. The Notes have not been registered under the Securities Act, or any applicable state securities laws, and will be offered only to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act and outside the United States to non-U.S. persons in accordance with Regulation S under the Securities Act. Unless so registered, the Notes may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act and any applicable state securities laws.

Forward-looking statements often are preceded by words such as “believes,” “expects,” “may,” “anticipates,” “plans,” “intends,” “assumes,” “will” or similar expressions. The forward-looking statements contained herein include statements about the tender offer for the 2030 Notes, the Company’s Notes offering and its intended use of proceeds therefrom. These expectations may or may not be realized. Some of these expectations may be based upon assumptions or judgments that prove to be incorrect. In addition, GeoPark’s business and operations involve numerous risks and uncertainties, many of which are beyond the control of GeoPark, which could result in GeoPark’s expectations not being realized or otherwise materially affect the financial condition, results of operations and cash flows of GeoPark. Some of the factors that could cause future results to materially differ from recent results or those projected in forward-looking statements are described in GeoPark’s filings with the United States Securities and Exchange Commission.
