Colombia: Drilling Underway to Grow Production, Extend Field Boundaries and Test New High Potential Prospects

In the CPO-5 block (GeoPark non-operated, 30% WI) - Llanos basin:

• Two drilling rigs contracted for two years targeting development, appraisal and high potential near-field exploration projects adjacent to and on trend with core Llanos 34 block (GeoPark operated, 45% WI)
• One rig currently drilling the Indico 4 development well / Second rig expected to spud in 1Q2022
• Second exploratory phase of CPO-5 E&P Contract extended by Colombian government to July 2024¹

In the Llanos 34 block - Llanos basin:

• November 2021 exit production above 60,000 bopd gross, the highest level since October 2020
• Recent successful results in the Tigui area, expanding field limits and opening new drilling opportunities
• Jacana 49 development well was drilled in November 2021 and is currently producing approximately 1,100 bopd from the Guadalupe formation with a 1% water cut. The well shows higher productivity rates and improved reservoir conditions than neighboring wells, opening new drilling opportunities that will be tested in 2022. Jacana 49 is located close to the southwest limits of the field and 1.7 km from the CPO-5 block

In the Platanillo block (GeoPark operated, 100% WI) - Putumayo basin:

• Successfully drilled the Alea Oeste 1 development well, with completion and testing activities currently underway. A new development well, Platanillo Central 1 expected to be spudded before end-2021

Ecuador: Spudded First Test of Attractive Low Risk Short-Cycle Exploration Inventory

• Production in the Manati gas field (GeoPark non-operated, 10% WI) was suspended from December 10 to December 17, 2021 due to repairs in a valve in the submerged part of the field's pipeline

2022 Work Program: Multiple Catalysts Ahead

• Self-funded 2022 capital expenditures program of $160-180 million targeting drilling of 40-48 gross wells (20-25% higher than 2021E), including 15-20 gross exploration/appraisal wells (~4x higher than 2021E)
• Using a $65-70 per bbl Brent base case, GeoPark expects to generate a free cash flow of $90-140 million (after mandatory debt service payments), equivalent to a 14-20% free cash flow yield²
