Tullow completes sale of Kenya assets to Gulf Energy Ltd

25 September 2025 - Tullow Oil plc (Tullow) is pleased to announce that it has successfully completed the sale of its entire working interest in Kenya to Auron Energy E&P Limited, an affiliate of Gulf Energy Ltd, following satisfaction of all conditions precedent under the Sale and Purchase Agreement (SPA) announced on 21 July 2025. Tullow has received the full proceeds of Tranche A (US$40 million) under the terms of the SPA. The transaction represents the sale of 100% of the shares in Tullow's subsidiary Tullow Kenya BV, which holds Tullow's entire working interests in Kenya, for a minimum cash consideration of US$120 million, subject to customary adjustments. The transaction proceeds will be used to strengthen Tullow's balance sheet.

The sale of its Kenya subsidiary marks Tullow's exit from the country after 14 years. Tullow retains royalty payments, subject to certain conditions, and a no cost back-in right for a 30% participation in potential future development phases.

Ian Perks, Chief Executive Officer of Tullow, commented:

"The successful completion of this transaction marks a significant milestone for the company and the achievement of another one of our key 2025 strategic priorities. The use of proceeds helps to further strengthen our balance sheet and I would like to thank the team for their hard work and commitment, which have helped position the company strongly as we look to refinance our capital structure this year.

On behalf of everyone at Tullow, I extend our best wishes to the people and Government of Kenya and wish Gulf Energy every success as they advance this project."

Paul Limoh, Chief Executive Officer, Gulf Energy Ltd, commented:

"We are delighted to complete this transaction and to bring these assets under the stewardship Gulf Energy Ltd. This project will play an important role in advancing Kenya's domestic energy sector, creating opportunities for growth and development in the Turkana region, as well as supporting the country's long-term energy security. We thank Tullow for its years of investment and commitment, and we look forward to building on that foundation as we work with partners and stakeholders to take the project forward."
