[1] See press releases dated March 8, April 11, May 3 and July 17, 2023.[2] ROCE is defined as last twelve-month operating profit divided by average total assets minus current liabilities.[3] Based on GeoPark’s average market capitalization from July 1 to July 31, 2023.[4] From July to December 2023.[5] Free cash flow is used here as Adjusted EBITDA less capital expenditures, mandatory interest payments and cash taxes. 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. Adjusted EBITDA assumes a Brent to Vasconia differential averaging $4-5 per bbl from July to December 2023.CONFERENCE CALL INFORMATIONReporting Date and Conference Call for 2Q2023 Financial ResultsIn conjunction with the 2Q2023 results press release, GeoPark management will host a conference call on August 10, 2023, at 10:00 am (Eastern Daylight Time).To listen to the call, participants can access the webcast located in the Invest with Us section of the Company’s website at www.geo-park.com, or by clicking below:https://events.q4inc.com/attendee/893129503Interested parties may participate in the conference call by dialing the numbers provided below:United States Participants: +1 404 975 4839International Participants: +1 929-526-1599Passcode: 931988Please allow extra time prior to the call to visit the website and download any streaming media software that might be required to listen to the webcast.An archive of the webcast replay will be made available in the Invest with Us section of the Company’s website at www.geo-park.com after the conclusion of the live call.For further information, please contact: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
