Board Changes and Financial Reporting Update

Savannah Energy PLC, the British independent energy company focused around the delivery of Projects that Matter in Africa, announces several planned Board changes, in line with the Company's succession planning regime.

Sir Stephen O'Brien and David Clarkson have retired from the Board. Savannah extends its sincere thanks to both for their dedication and service as Directors over the past eight years. During their tenure they have been instrumental in supporting the Company's governance framework and Board processes.

Savannah is also pleased to announce the intended appointments of Uyi Akpata and Kehinde Olamide Ogunwumiju as Independent Non-Executive Directors. Uyi and Kehinde bring significant experience in audit, finance and legal affairs, further strengthening the Board's capabilities in these key areas. Upon joining the Board, Mr Akpata is expected to serve as Chair of the Audit Committee.¹

Joseph Pagop Noupoué, Chairman of Savannah, commented:

 "The changes announced this morning form part of Savannah's ongoing and dynamic Board succession planning process, which is designed to evolve in step with the Company's strategic direction, operational priorities, and growth trajectory.

On behalf of the Board, I would like to wish Sir Stephen and David every success in the future. As part of our structured approach to Board renewal, their agreed retirement reflects the natural progression of our governance planning. That said, both have been highly valued colleagues whose insight, integrity, and presence around the Board table will be genuinely missed. We are delighted that both have agreed to take on ongoing consultancy roles, ensuring the Company can continue to benefit from their extensive experience and deep understanding of our business. We wish them every success in the future and thank them wholeheartedly for their service.

I am also delighted to welcome Uye and Kehinde as incoming Directors. Both are internationally respected professionals in their respective fields - finance and legal - and have proven track records supporting dynamic, high growth organisations. I believe their expertise will be instrumental as Savannah continues its growth trajectory across Africa."

Sir Stephen O'Brien, Retiring Vice Chair and Non-Executive Director, Savannah, commented:

"Having been involved with the Company since its very inception 11 years ago, and after eight stimulating years as Vice-Chairman of Savannah, I am stepping down with pride in what has been built together as a team. Over this time, Savannah has transformed into a leading African energy company, advancing projects across the continent in both hydrocarbons and renewables. I am pleased to have had the opportunity to contribute to our journey. I wish everyone at Savannah every success and look forward to maintaining my support for the company in a new political advisory role."

David Clarkson, Retiring Non-Executive Director, Savannah, commented:

"Since joining the Board in 2017, I have enjoyed a wonderful journey with Andrew and my Board colleagues as Savannah grew in stature delivering Projects That Matter. I wish the Company every success as it continues to build sustainable businesses across its portfolio of opportunities. I look forward to supporting the Company as Technical Advisor to the Board."
