GeoPark Limited Announces Commencement of Consent Solicitation with Respect to Its 8.750% Senior Notes Due 2030

Bogota, Colombia, Sept. 15, 2026 (GLOBE NEWSWIRE) -- GeoPark Limited (NYSE: GPRK) (the “Company” or “GeoPark”) today announced that it is soliciting consent (the “Consent Solicitation”) from the holders of its 8.750% Senior Notes due 2030 (the “Notes”) for the adoption of a certain proposed amendment (the “Proposed Amendment”) to the indenture governing the Notes (the “Indenture”) to amend the definition of "Permitted Holders" in the Indenture to include Jaime Gilinski Bacal and his Immediate Family Members (as defined in the Indenture) or the former spouses (including widows and widowers), heirs or lineal descendants of any of the foregoing and any Affiliate of any of the foregoing. Jaime Gilinski Bacal is affiliated with Grupo Gilinski, which through affiliated entities has through a number of transactions recently purchased approximately 28% of the Company's issued and outstanding common shares. GeoPark’s recently announced proposed major strategic entry into Venezuela through the Bare field, a large-scale producing heavy oil asset located in the Orinoco Heavy Oil Belt, was led by Grupo Gilinski. GeoPark is acquiring Grupo Gilinski’s 95% interest in the holding company through which the Bare opportunity is held in exchange for newly issued common shares. The proposed transaction has not yet closed and remains subject to certain conditions. Upon completion of the share issuance, Grupo Gilinski is expected to hold approximately 56.3% of GeoPark’s issued and outstanding common shares. Pursuant to the Indenture, a "Change of Control" will generally not be triggered by the consummation of a transaction the result of which is that a Permitted Holder becomes the beneficial owner of more than 50% of the outstanding shares. Pursuant to the Indenture, if a Change of Control occurs, the Company is required to make an Offer to Purchase (as defined in the Indenture) for all of the outstanding Notes.

The Consent Solicitation is being made pursuant to a Consent Solicitation Statement, dated September 15, 2026 (as may be amended or supplemented from time to time, the “Consent Solicitation Statement”). The Consent Solicitation was commenced today and will expire at 5:00 p.m., New York City time, on September 23, 2026, unless extended by the Company (each such date and time, as the same may be extended, is referred to as the “Expiration Time”). Only holders of the Notes as of 5:00 p.m., New York City time, on September 14, 2026 (such date and time, including as such date and time may be changed by the Company, from time to time, the “Record Date”) are entitled to consent to the Proposed Amendment pursuant to the Consent Solicitation.

The Proposed Amendment will be set forth in a supplemental indenture relating to the Notes and are described in more detail in the Consent Solicitation Statement. To amend the Indenture, the Company must receive consents from holders (as of the Record Date) representing a majority in aggregate principal amount outstanding (not including any Notes which are owned by the Company or any of its affiliates) of the Notes (the “Requisite Consents”).

With respect to the Consent Solicitation, the Company will, within five business days of the Expiration Time, provided that all applicable conditions to the Consent Solicitation as described in the Consent Solicitation Statement have been satisfied or waived, pay to holders of the Notes, a cash payment equal to $2.50 per $1,000 principal amount of Notes in respect of which such consents have been validly delivered prior to the Expiration Time and not validly revoked by such holders as total consideration for such consent (the “Consent Fee”). No Consent Fee will be paid to any holder of Notes unless such holder delivers a consent in accordance with the terms of the Consent Solicitation Statement prior to the Expiration Time. The consummation of the Consent Solicitation is conditioned on the receipt of the Requisite Consents.

Subject to applicable law, the Company reserves the right, in its sole discretion, to (i) extend, terminate or withdraw the Consent Solicitation at any time, or (ii) otherwise amend the Consent Solicitation in any respect, including waiving any or all of the conditions to the Consent Solicitation set forth in the Consent Solicitation Statement, at any time and from time to time. The Company further reserves the right, in its sole discretion, not to accept any deliveries of consents with respect to the Notes. The Company is making the Consent Solicitation only in those jurisdictions where it is legal to do so.
