Solid Delivery Across Core Assets With Waterflooding Exceeding Plan

Strategic Expansion Into Vaca Muerta Following Closure of Acquisition

BOGOTA, Colombia--(BUSINESS WIRE)--

GeoPark Limited ( GPRK ) (“GeoPark” or the “Company”) , a leading independent energy company with over 20 years of successful operations across Latin America, announces its operational update for the three-month period ended September 30, 2025 (“3Q2025”).

Oil and Gas Production and Operations

January-September consolidated average oil and gas production of 28,194 boepd

3Q2025 consolidated average oil and gas production of 28,136 boepd, reflecting solid delivery from core operated and non-operated assets

Production was 3% higher than 2Q2025, mainly explained by stronger performance across core assets. Ongoing waterflood and workover activities at Llanos 34 (GeoPark ( GPRK ) operated, 45% WI) delivered higher than expected production, there was improved production from the CPO-5 Block (GeoPark ( GPRK ) non-operated, 30% WI) in the absence of blockades, and output from the Manati gas field (GeoPark ( GPRK ) non-operated, 10% WI) in Brazil increased from an average of 350 to 1,000 boepd during the quarter1

A total of 4 wells were drilled and completed in 3Q2025, bringing the total at end-September to 14 wells

Llanos 34 Block: Waterflood and Workovers Sustain Base Amid Weather Impacts

3Q2025 average production of 16,953 boepd net (37,674 boepd gross), down 4% from 2Q2025 consistent with expected decline rates. Performance was further impacted by a force majeure flooding event and reduced output from the on-site power network

Waterflooding projects contributed approximately 5,698 boepd gross (15% of gross production), exceeding plan by 14%

Workover campaign focused on 18 wells, delivering 2,250 boepd gross and reducing water production by 25,200 bwpd from November 2024 to September 2025, exceeding plan by 4%

CPO-5 Block: Production Rebound and Reduced Downtime

3Q2025 average production reached 7,075 bopd net (23,583 bopd gross), up 16% from 2Q2025, primarily driven by strong performance at the Indico field and reduced downtime

Environmental license modification for the Indico and Mariposa fields has been approved, enabling key operational initiatives including water disposal

Llanos Exploration: Drilling Success Continues

3Q2025 average production increased to 2,180 boepd net (4,360 boepd gross), driven by the Llanos 123 Block (GeoPark ( GPRK ) operated, 50% WI):

Currucutu-1: Additional potential identified in the Mirador formation under evaluation. A workover is planned in 1H2026 to assess its productivity

Toritos Sur-3: Drilled and completed during June 2025 with initial production tests of 1,070 bopd (1% BSW) from the Mirador formation (exploration target) and 630 bopd (
