Tony Elumelu’s rise to Seplat chair signals new phase for indigenous energy giant

Seplat Energy Plc is set for a major leadership transition that will culminate in the appointment of businessman and philanthropist Tony Elumelu as Chairman of the board from January 1, 2027, marking what industry watchers describe as a defining moment for one of Nigeria’s leading indigenous energy companies.

The company announced a series of board and executive management changes on Wednesday, outlining a carefully structured succession plan designed to reinforce governance continuity while steering its long-term growth strategy.

Under the arrangement, current Chairman Senator Udo Udoma will retire on December 31, 2026, paving the way for Elumelu, who joined the board in January 2026, to assume leadership of the board.

Elumelu’s appointment places one of Africa’s most influential investors at the helm of Seplat at a time when the company is consolidating its position in Nigeria’s upstream oil and gas sector following years of aggressive expansion.

A statement from the company noted that Elumelu, Founder and Chairman of Heirs Holdings, brings extensive investment experience across energy, banking, insurance, technology and other key sectors of the African economy. Heirs Holdings holds a 20.07 per cent stake in Seplat Energy.

Describing him as a “distinguished philanthropist and leading voice on Africa’s transformation,” the board said his appointment reflects confidence in his long-term value creation record across listed and non-listed companies.

The leadership transition also extends to the executive arm of the company, with Chief Executive Officer Roger Brown set to retire on July 31, 2026, after more than a decade of involvement in Seplat’s evolution.

Brown’s tenure, which began as Chief Financial Officer in 2013 before his elevation to CEO in 2020, coincided with some of Seplat’s most transformative milestones, including its dual listing in 2014 and major acquisitions such as Eland Oil and Gas in 2019 and Mobil Producing Nigeria Unlimited in 2024.

The company credited him with strengthening financial discipline, expanding its asset base and enhancing shareholder returns during a period of significant industry volatility.

To ensure continuity, Seplat has appointed Effiong Okon as the incoming Chief Executive Officer and Executive Director, effective August 1, 2026. Okon will succeed Brown and lead the company into its next phase of expansion.

Okon, a seasoned oil and gas executive with more than 35 years of global experience, has been closely involved with Seplat since 2018, serving in several strategic roles including Operations Director, New Energy Director, and most recently Managing Director of the ANOH Gas Processing Company.

The company noted that under his leadership, the ANOH project successfully achieved first gas in January 2026, a milestone considered critical to Nigeria’s domestic gas development agenda.

Outgoing CEO Brown expressed satisfaction with his tenure, describing Seplat as a company built on “financial resilience, disciplined capital allocation and strong governance culture.”

Incoming Chairman Elumelu, in his remarks, said he was honoured to succeed Senator Udoma and pledged to support the company’s next phase of growth, with a focus on unlocking value from indigenous resources across Africa’s energy landscape.

He also congratulated the incoming CEO, expressing confidence in his ability to deliver on Seplat’s long-term roadmap through 2030 and beyond.

The leadership reshuffle positions Seplat Energy at a pivotal moment, as the company balances expansion ambitions with governance continuity in an evolving African energy market increasingly shaped by local ownership and global capital dynamics.
