Proposed NYSE listing, cancellation of admission to trading on AIM and adoption of New Bye- Laws

1. NYSE listing

The Company is pleased to announce that it has commenced an initial public offering in the United States of America (“US”) in connection with its proposed listing on the New York Stock Exchange (“NYSE”). As previously announced on 10 September 2013 and 22 October 2013, GeoPark is seeking a listing on the NYSE in order to create a public market for its common shares (“Shares”) in the United States and to facilitate future access by the Company to the international equity markets, as well as to obtain additional capital and financial flexibility.

The Company has commenced an initial public offering in the US of 20,000,000 of its Shares, at an expected price range between US$8.00 to US$10.00 per Share (“US Offering”). The Shares will be registered with the US Securities and Exchange Commission (“SEC”) and have been approved to be listed on the NYSE, subject to notice of issuance, under the ticker symbol “GPRK”. GeoPark also intends to grant the proposed underwriters a 30-day option to purchase up to 3,000,000 additional Shares at the initial public offering price.

The Company may use a portion of the proceeds from the US Offering to finance or accelerate the expansion of its operations in its current asset base and, following the completion of pending acquisitions in Brazil, its Brazilian assets, or use the proceeds for general corporate purposes. In addition, the Company may use a portion of the proceeds from the US Offering for opportunistic acquisitions in Chile, Colombia and Brazil as well as in other countries in South America, which may include Peru, although the Company does not have definitive plans or arrangements with respect to any potential asset in South America.

The US Offering will be made only by means of a prospectus. When available, copies of the preliminary prospectus relating to the offering may be obtained from J.P.
