In order to ensure an orderly transition, Dr A.B.C.

"The past twelve years of Seplat Energy's existence have been phenomenal for me. As Chairman, I am proud that the Board, Management and entire Staff of Seplat Energy, were able to achieve several enviable milestones and exceptional successes, notably the acquisition of eight oil and gas assets, expansion of the Oben and development of the ANOH gas plants and the dual listing on both the Nigerian and London Stock Exchanges, a first by a Nigerian company. While there were challenges along the way, we overcame these by the special grace of God, the outstanding performance and professionalism of each member of the Board and Management and the sterling efforts of our Staff. I will continue to give my utmost energy and commitment to the Company until I step down from the Board at the next AGM."

Mr. Basil Omiyi, Senior Independent Director of Seplat Energy plc, commented today:

"On behalf of all members of the Board, I would like to thank Dr A.B.C. Orjiako for his immense contribution as a co-founder and Chair of Seplat Energy since inception. He has been Chairman during exciting times and his dedication has been constant throughout. The Board looks forward to working with him during the transition period and we will miss his insight, expertise and leadership when he finally steps down in May 2022."
