Under his leadership, Petralon Energy has emerged as a significant indigenous operator in Nigeria’s upstream sector. The company is the Operator and sole licensee of the Dawes Island Field and has invested over US$50 million in its development, with commercial production commencing in July 2025. Ahonsi has been instrumental in securing more than US$1 billion in financing commitments for Petralon’s ventures from reputable international financiers, including a Tier-1 global crude trader and a leading hedge fund manager with assets under management exceeding US$20 billion.
In 2021 and 2022, Petralon successfully acquired interests in Prime Oil & Gas Coöperatief U.A., raising over US$60 million to complete the transaction—further strengthening its asset base and long-term growth strategy.
Before founding Petralon, Ahonsi accumulated over a decade of investment banking and project finance experience across Europe and Africa. At Citigroup, he served as Manager in Project and Corporate Finance, and later at Standard Bank as Director and Head of the Government, International Organisations, and Project Finance Divisions. Across these roles, he executed over US$3 billion in cross-border and local currency financings, particularly in the oil & gas and telecommunications sectors.
He played key roles in several landmark transactions, including the US$1.06 billion brownfield project financing for Nigeria LNG Ltd., the US$160 million financing for Eleme Petrochemicals, and the US$395 million medium-term financing for MTN Nigeria. These transactions were pivotal in strengthening Nigeria’s energy and telecommunications infrastructure and demonstrated his expertise in structuring complex, large-scale financings.
At Standard Bank, he was pivotal in originating the merger between Stanbic Bank and IBTC Bank Plc—one of the largest banking and capital markets transactions in Nigeria at the time. He also contributed to the landmark 2008 Lagos State Government debut bond issuance of N275 billion (US$1.83 billion), one of the largest sub-sovereign bond issues in Nigeria’s history.
Ahonsi has also served at both federal and state levels within Nigeria’s public sector. As Special Adviser to the Minister of Finance (2006–2007), he was part of the team that successfully negotiated Nigeria’s exit from the London and Paris Club creditors. Between 2009 and 2011, he served as Commissioner for Budget, Planning and Economic Development in Edo State, where he rebuilt relationships with major multilateral development partners and played a key role in securing World Bank Budget Support for the state.
Prior to Petralon, he was a founding executive of First Hydrocarbon Nigeria, serving as Chief Financial Officer and Executive Director. He led the US$147.5 million acquisition financing of OML 26 from the Shell JV and structured the first reserve-based lending for an onshore Niger Delta oil block, raising US$230 million from a consortium of banks. Within three years, he raised over US$400 million in debt, equity, and project financing for the company.
He currently serves as Chairman of Nigerian Exchange Limited (NGX), Director of Meren Energy Inc. (formerly Africa Oil), listed on the TSX and Nasdaq Stockholm, and Chairman of Marconi.NG EPC Limited.
A recipient of the 2009 Archbishop Desmond Tutu Leadership Fellowship Award and a 2025 honoree of MIPAD’s Global Top 50 Finance and Capital Edition, Ahonsi is widely recognized for his leadership, integrity, and impact.
He holds an MSc in Investment Banking and Finance and a BA (Hons.) in Economics. Bilingual in English and French, he is happily married with four children and enjoys tennis and running.
