The appointment was disclosed in a notice filed on the Nigerian Exchange Limited (NGX) on Tuesday and signed by the company secretary, Edith Onwuchekwa.

Engr. Effiong Okon was also announced as the company’s new Chief Executive Officer, effective August 1, 2026, replacing current CEO, Roger Brown.

Elumelu recently acquired a 20.07% stake in the company through Heirs Energies in a $500 million transaction, making him the single largest shareholder in the dual-listed energy company.
