Seplat Energy has announced a major leadership transition that will see prominent Nigerian businessman Tony Elumelu assume the role of board chairman from January 1, 2027, while current executive director Effiong Okon steps in as chief executive officer from August 1, 2026. The changes, disclosed on June 9, are part of a broader succession plan tied to the company’s long-term growth and energy transition strategy.
Elumelu, who joined Seplat’s board earlier this year as a non-executive director, became a significant shareholder following a $496 million acquisition of a 20.07% stake through his investment vehicle. His elevation to chairman signals a deepening influence over the company’s strategic direction, particularly as it seeks to expand its footprint in Nigeria’s gas sector and position itself for a lower-carbon future.
The incoming CEO, Effiong Okon, will replace Roger Brown, who is set to retire after leading the company through a period of expansion. Brown’s tenure saw Seplat execute key acquisitions and scale production to 131,506 barrels of oil equivalent per day (boepd) in 2025, strengthening its position as one of Nigeria’s leading indigenous energy firms.
In a statement, Elumelu described the transition as a “natural progression” aligned with Seplat’s ambition to drive indigenous participation in Africa’s energy sector. “This is about building a resilient, African-led energy company that can compete globally while delivering value at home,” he said.
Industry analysts view the leadership shift as both strategic and symbolic. Elumelu’s track record in banking and energy investments, coupled with his advocacy for private sector-led development in Africa, is expected to shape Seplat’s next phase—particularly its “Roadmap 2030,” which prioritizes gas development and cleaner energy solutions.
Okon, an engineer with extensive experience within the company, is seen as a continuity candidate. His appointment suggests stability in operations while the company navigates evolving market conditions, regulatory pressures, and the global push toward decarbonization.
Seplat has increasingly positioned natural gas as a bridge fuel in Nigeria’s energy mix, capitalizing on the country’s vast reserves to meet domestic power needs and support industrial growth. The company’s leadership believes this approach will balance economic development with environmental responsibility.
As the transition unfolds over the next year, stakeholders will be watching closely to see how the new leadership team executes its strategy amid shifting global energy dynamics. For Seplat, the changes mark not just a смена of guard, but a recalibration toward long-term sustainability and African-led growth in the energy sector.
I am honoured to succeed Senator Udoma as Chairman in January 2027 and to lead the Board through @SeplatEnergy ’s next phase of growth.
