Growth comparisons refer to the same period of the prior year, except when otherwise specified.Oil and Gas ProductionConsolidated average oil and gas production down 4% to 36,578 boepd1, below its production potential of approximately 39,500-40,500 boepd, as previously announced on March 8, 2023, mainly due to temporarily shut-in production and localized blockades in the CPO-5 block (GeoPark non-operated, 30% WI) in ColombiaCurrently producing approximately 38,000 boepdLlanos BasinLlanos 34 block (GeoPark operated, 45% WI):Average gross production of 54,799 bopdFour drilling and four workover rigs currently in operationGeoPark drilled its first horizontal development well in the block in the Tigana fieldProduction tests initiated in late March 2023The well was drilled within time and budget to a total depth of 13,862 feet and a horizontal lateral length of 1,270 feetThe well is currently producing over 3,000 bopd with 01% water cut from the Mirador formationBased on these results, GeoPark is evaluating drilling additional horizontal wells in 2023The Llanos 34 block is currently producing approximately 57,000 bopdCPO-5 block:Average gross production of 16,707 bopd, below its production potential of approximately 25,000-26,000 bopd gross, due to shut-in production of the Indico 6 and Indico 7 wells and to a lesser extent, localized blockades, as previously announced on March 8, 2023The operator expects to resume production in the Indico 6 and Indico 7 wells in May 2023These two wells were drilled in late 2022 and together tested over 11,000 bopd gross (or 3,300 bopd net to GeoPark)The two wells remained shut in for most of 1Q20232 after the regulator (ANH) requested the operator suspend production until definitive surface facilities are completedOverall production and operations in the block affected for 9 days in 1Q2023 due to localized blockadesYarico 1 exploration well, targeting an exploration prospect adjacent to the Mariposa field, reached total depth in March 2023According to petrophysical logging interpretation, the well encountered reservoir in the Guadalupe formation, with no evidence of hydrocarbons and depending on injectivity evaluations, may be converted to a disposal well in the futureDrilling activities are expected to continue with the Halcon 1 well, targeting an exploration prospect in the northern part of the block, adjacent to the Llanos 34 block, expected to be spudded in 3Q2023Llanos 87 block (GeoPark operated, 50% WI):Tororoi 1 exploration well reached total depth in December 2022Production tests in the Mirador formation started in March 2023 and the well is currently producing 240 bopd of light oil with a 1% water cutZorzal 1 exploration well reached total depth in February 2023Preliminary logging information indicates hydrocarbons in the Barco formationInitial production tests flowed light oil from the Barco formationResults so far are inconclusive, additional production tests are expected to continue in the next few weeksPicabuey 1 and Koala 1 exploration wells reached total depth in 1Q2023The wells encountered reservoirs in the Barco and Ubaque formations with no evidence of hydrocarbons and the wells were abandonedLlanos 123 and Llanos 124 blocks (GeoPark operated, 50% WI):Civil works and other activities currently underway in order to spud 2-3 exploration wells in

Percentages are calculated adjusting for divestments in Argentina in 1Q2022.2 Indico 6 was shut in in December 2022 and Indico 7 was shut in in early January 2023.3 Scopes 1 and 2.4 Based on GeoPark’s average market capitalization during March 2023.5 Unaudited.6 Free cash flow is used here as Adjusted EBITDA less capital expenditures, mandatory interest payments and cash taxes. 2023 cash taxes include GeoPark’s preliminary estimates of the full impact of the new tax reform in Colombia, irrespective of the timing of its cash impact, expected in 2023 or early 2024. The Company is unable to present a quantitative reconciliation of the 2023 Adjusted EBITDA which is a forward-looking non-GAAP measure, because the Company cannot reliably predict certain of its necessary components, such as write-off of unsuccessful exploration efforts or impairment loss on non-financial assets, etc. Since free cash flow is calculated based on Adjusted EBITDA, for similar reasons, the Company does not provide a quantitative reconciliation of the 2023 free cash flow forecast.INVESTORS:Stacy Steimel ssteimel@geo-park.com Shareholder Value Director T: +562 2242 9600Miguel Bello mbello@geo-park.com Market Access Director T: +562 2242 9600Diego Gully dgully@geo-park.com Investor Relations Director T: +5411 4312 9400MEDIA: Communications Department communications@geo-park.com SHARE
