SINTANA ENERGY INC. - Management Update

Sintana Energy Inc.’s latest investor update outlined a capital-efficient frontier exploration strategy focused on high-impact opportunities across Namibia, Uruguay and Angola, with a portfolio designed to provide asymmetric exposure to potentially transformational discoveries. The Company highlighted its indirect interest in the Mopane discovery on PEL 83 in Namibia, where TotalEnergies has taken operatorship and plans a three-well exploration and appraisal programme, with activity expected to support resource growth and potential development planning. Sintana also has significant exploration exposure in Uruguay, including the AREA 1 licence where Chevron has completed its first 3D seismic campaign and is progressing towards further seismic work and a potential drilling decision. Additional catalysts include Chevron’s planned exploration well on PEL 90 in Namibia, activity in the Walvis Basin, progress on an Angola transaction and potential farm-outs across the portfolio. Management emphasised the Company’s capital-efficient model, with major partners such as TotalEnergies and Chevron funding substantial exploration activity while Sintana retains exposure to potential high-value outcomes. The Group also reported progress against its 2026 objectives, including securing funding, a $9 million settlement with Exxon relating to legacy Colombian assets and advancing targeted business development opportunities. With multiple wells, seismic results, farm-outs, development milestones and exploration decisions expected across 2026 and 2027, Sintana believes its diversified portfolio provides multiple catalysts for potential value creation and long-term shareholder returns.
