Udoma Udo Udoma’s Legacy at Seplat Energy
Udoma Udo Udoma, who has chaired Seplat Energy since April 2024, leaves behind a legacy of strategic leadership marked by key acquisitions, operational growth, and progress toward the company’s long-term 2030 objectives.
The former senator and Minister of Budget and National Planning brought extensive experience in governance, corporate leadership, and petroleum law to the boardroom. His stewardship helped guide the company through critical expansion phases while strengthening corporate governance and shareholder confidence.
Beyond public service, Udoma is widely respected within Nigeria’s corporate and legal circles for his expertise in energy, investment, and commercial law.
Tony Elumelu’s Growing Influence in the Energy Sector
Elumelu joined Seplat Energy’s Board as a Non-Executive Director in January 2026 following the acquisition of a significant equity stake by Heirs Energies.
The investment, valued at approximately $500 million, gave Heirs Energies an estimated 20 percent stake in Seplat, positioning it among the company’s largest shareholders.
As Founder and Chairman of Heirs Holdings, Elumelu oversees investments across banking, power, energy, hospitality, healthcare, and technology sectors. He is also Chairman of UBA Group and Transcorp Group, institutions that have played pivotal roles in Africa’s economic development.

Elumelu is internationally recognized for promoting “Africapitalism,” a philosophy that advocates private sector-led economic growth and sustainable development across the African continent.
Through the Tony Elumelu Foundation, he has supported thousands of entrepreneurs across Africa with funding, mentorship, and business training.
What the Leadership Change Means for Seplat Energy
Industry analysts believe Elumelu’s appointment could further strengthen Seplat Energy’s growth trajectory through expanded investment opportunities, stronger strategic partnerships, and enhanced indigenous participation in the energy sector.
The leadership transition comes at a crucial period for the company as it seeks to consolidate recent gains from acquisitions and increase production capacity while navigating evolving energy market dynamics.
Observers also expect Elumelu’s extensive business network and investment expertise to support Seplat’s ambitions in gas development, power generation, and sustainable energy initiatives.
New CEO to Lead Operations
As part of the broader leadership transition, Seplat Energy has appointed Engr. Effiong Okon as Chief Executive Officer effective August 1, 2026.
Okon, a veteran of Nigeria’s oil and gas industry with more than three decades of experience, will succeed Roger Brown and is expected to focus on operational efficiency, production growth, and long-term value creation.
A New Chapter for Indigenous Energy Leadership
The succession plan reflects the growing role of indigenous investors and business leaders in shaping the future of Nigeria’s energy industry.
As international energy markets evolve, Seplat Energy’s leadership transition signals confidence in homegrown expertise and African-led enterprise.
With Tony Elumelu set to assume the chairmanship and a new CEO taking charge of operations, stakeholders will closely monitor how the company leverages its resources, expands its footprint, and contributes to Nigeria’s energy security and economic development.
The transition remains subject to regulatory approvals and final board processes.
