Transactions Highlights:

Gil Holzman, President and Chief Executive Officer of Eco Atlantic, commented:

"This successful farm down of our Namibian Walvis Basin Licenses marks an incredible moment for Namibia, for Eco Atlantic and its shareholders.  This transaction is a clear demonstration of our strategy partnering with Supermajors and IOC's, to derisk our portfolio while retaining material exposure to significant upside potential with very limited financial requirements from Eco.  Eco entered Namibia in 2011, with a firm belief of the Walvis basin subsurface potential, and we are proud to attract an IOC of BP's calibre to further explore this prospective basin.  We look forward to continuing our excellent working relationship with BP's dynamic and experienced team and welcome them to the Land of the Brave."

"I am extremely grateful to our Namibia country manager, Tironenn Kauluma, as well as my dedicated team and our legal advisors at Cliffe Dekker Hofmeyr, for their tireless efforts over the past few months in delivering this monumental transaction for Eco shareholders and our Namibian Stakeholders. We are also deeply appreciative of the ongoing support, guidance and cooperation we always have from the Petroleum Commissioner at the Ministry of Mines and Energy, her team, and the Upstream Petroleum Unit at the state house."

"In parallel Eco has been progressing closing of the JHI Acquisition, and Eco and Navitas continue advanced discussions with the Government of Guyana regarding appraisal and exploration activities on the Orinduik block, while progressing lead and prospect evaluation on Block 1 CBK in South Africa's Orange basin. We will provide market updates as further developments arise within our broader Atlantic margin portfolio."

Details of the Transaction

Pursuant to the terms of the FOA, completion of the Transaction ("Completion") is subject to the satisfaction of customary conditions precedent including, but not limited to, the receipt of requisite regulatory approvals (Section 11 and grant of First Renewal Period) from the government of Namibia.  On Completion, the PEL097 interests of the JV partners will be as follows: BP Namibia Energy Ltd will become the Operator of the Block, holding a 60% Participating Interest; Eco Oil & Gas Namibia (PTY) Limited, will hold a 25% Participating Interest; NAMCOR will retain a 10% Participating Interest;  Tangi Trading Enterprise CC, will retain a Participating Interest of 5%.  On Completion, the PEL099 interests of the JV partners will be as follows: BP Namibia Energy Ltd will become the Operator of the Block, holding a 60% Participating Interest; Eco Oil & Gas Namibia (PTY) Limited, will hold a 25% Participating Interest; NAMCOR will retain a 10% Participating Interest;  Lotus Exploration (Pty) Ltd, will retain a Participating Interest of 5%.  On Completion, the PEL100 interests of the JV partners will be as follows: BP Namibia Energy Ltd will become the Operator of the Block, holding a 60% Participating Interest; Eco Oil & Gas Services (PTY) Limited, will hold a 25% Participating Interest; NAMCOR will retain a 10% Participating Interest;  Moonshade Investments (Pty) Ltd, will retain a Participating Interest of 5%. 

The Cooper License, the Guy License and the Tamar License have a book value of US$10.95 million and Eco's spend for the year ended 31 March 2025 on the Namibia Licenses was approximately US$1.4 million.
