OFFICIAL STATEMENT: 9 June 2026: The Board of Seplat Energy PLC ('Seplat Energy' or the 'Company') today announces Board and executive management changes that will further support the Company's growth, whilst emphasising continuity in strategy and governance. CHIEF EXECUTIVE OFFICER SUCCESSION: After successfully leading the Company during a period of significant strategic expansion and transformation, including the acquisition of Mobil Producing Nigeria Unlimited ('MPNU'), Mr. Roger Brown will retire as Chief Executive Officer and as a Board Director on 31 July 2026. During Mr. Brown's 13-year tenure, initially as the Company's CFO through its landmark dual listing in 2014 and for the past 6 years as CEO, Seplat Energy has grown significantly through a combination of financial discipline, asset development and successful acquisitions, including Eland Oil and Gas in 2019 and the transformational acquisition of MPNU in 2024. Under Mr. Brown’s leadership, Seplat Energy has established itself as one of Africa's leading independent energy companies, with a strong pipeline of organic growth projects. The Board is pleased to announce the appointment of Engr. Effiong Okon as Chief Executive Officer and Executive Director commencing 1 August 2026. An accomplished leader with over 35 years of global industry expertise, he brings a formidable track record of operational excellence and strategic execution. He is deeply familiar with the organization having been with the Company since 2018, initially serving on Seplat Energy’s Board as Operations Director for four years, then as our New Energy Director and most recently as Managing Director of ANOH Gas Processing Company (‘AGPC’), where he successfully drove the project’s execution to achieve first gas in January 2026. Prior to joining Seplat Energy, Engr. Effiong cultivated a globally diverse operations portfolio during a distinguished career at Royal Dutch Shell spanning Africa, the USA, Europe, and the Middle East (full CV below). CHAIRMAN SUCCESSION PLAN: The Board also announces that the Chairman, Senator Udoma Udo Udoma, CON, has given notice of his intention to retire at the end of the year on 31 December 2026. Senator Udoma joined the Board in December 2023 and became Independent Chairman in April 2024. Since assuming the role, he has also worked closely with the Board and Management to oversee the successful integration of MPNU and setting out the 2030 strategic plan for the Company. Through his leadership and guidance, the Company has continued to thrive and play an increasingly important role in Nigeria’s energy sector. The Board has accordingly elected Mr. Tony O. Elumelu, CFR, as the next Chairman of Seplat Energy, effective 1 January 2027. Mr. Elumelu, who joined the Board in January 2026, is the Founder and Chairman of Heirs Holdings, which has a 20.07% shareholding in Seplat Energy. Heirs Holdings is a diversified investment company, with interests across strategic sectors of the African economy, including energy, power, banking, insurance, technology, real estate, hospitality, and healthcare. Mr. Elumelu has a multi-decade track record of value creation in listed and non-listed entities. Mr. Elumelu is also a distinguished philanthropist, globally recognised as one of the leading voices on Africa's transformation and governance agenda. The Board believes this succession plan will support the Company’s strategic vision as it executes delivery of its 2030 plan and strives to accelerate the growth projects in its portfolio. Congratulations @TonyOElumelu
