Elumelu’s Seplat stake rises to $1.28 billion as shares climb above N12,000
Tony Elumelu’s stake in Seplat Energy Plc, held indirectly through Heirs Energies Ltd and Heirs Holdings Ltd, has risen to approximately $1.28 billion, following another strong increase in the energy company’s share price.
The latest valuation is based on Seplat’s closing share price of N12,320.60 on Tuesday, September 1, 2026, representing a significant increase from the value of the stake disclosed in the company’s unaudited H1 2026 financial statements.
According to Seplat’s ownership disclosures, Elumelu holds 120.4 million shares, representing a 20.07% stake in the company. The holding makes the Heirs Group the company’s largest disclosed shareholder.
At Tuesday’s closing price, the stake is worth approximately N1.48 trillion, compared with about N1.37 trillion at June 30, when Seplat’s shares closed at N11,363.90.
This represents an increase of roughly N114 billion in market value in just over two months.
What you should know
Elumelu’s stake in Seplat represents one of the most significant individual investment positions in Nigeria’s listed energy sector.
The billionaire investor, through Heirs Holdings and Heirs Energies, acquired the 20.07% stake in December 2025 from French energy company Maurel & Prom for approximately $500 million.
Since then, Seplat’s share price has risen substantially, transforming the market value of the investment.
The increase illustrates how movements in the Nigerian equities market can rapidly change the value of large strategic holdings, particularly in heavyweight companies with relatively limited free float.
From $500 million investment to $1.28 billion stake
When Heirs Group acquired the 120.4 million Seplat shares in December 2025, the transaction was valued at approximately $500 million.
At the latest market price, the same stake is now worth about $1.28 billion.
That means the market value of the holding has increased by approximately $780 million based on the referenced valuations.
It is important to distinguish this from realised profit: the increase represents an unrealised gain based on Seplat’s market price. The actual return would depend on the price at which the shares are eventually sold, as well as dividends, taxes, transaction costs and currency movements.
Seplat’s share price continues to climb
The latest increase extends a remarkable run for Seplat shares in 2026.
The stock closed 2025 at approximately N5,809 per share before moving above N9,000 by March.
By April, Seplat became the first company listed on the Nigerian Exchange to cross the N10,000-per-share threshold.
The stock has since moved above N12,000, further increasing the value of major shareholder positions.
For Elumelu, the timing of the original investment has therefore proved highly significant.
A major bet on Nigeria’s energy sector
The Heirs Group investment came shortly after Seplat completed its acquisition of Mobil Producing Nigeria Unlimited (MPNU) from ExxonMobil.
The acquisition significantly expanded Seplat’s asset base and strengthened its position in Nigeria’s upstream oil and gas industry.
Heirs Group’s decision to take a substantial stake in Seplat was therefore effectively a major bet on the company’s enlarged asset portfolio and its ability to generate stronger long-term value from the expanded operations.
The subsequent rally in the share price suggests that investors have responded positively to the company’s enlarged position in the energy sector.
N114 billion added since the H1 valuation
The latest market price also highlights how quickly the value of a large equity position can change.
At June 30, 2026, Seplat’s closing price was N11,363.90, placing Elumelu’s 120.4 million shares at approximately N1.37 trillion.
By September 1, the stock had risen to N12,320.60, taking the same holding to approximately N1.48 trillion.
The difference is roughly N114 billion.
In other words, the market value of Elumelu’s disclosed Seplat stake has increased by more than N100 billion since the end of June without any additional shares being acquired.
The increase is entirely driven by the appreciation in Seplat’s share price.
Why Seplat matters to investors
Seplat has become increasingly important to Nigeria’s equity market because of its position as one of the country’s largest indigenous energy companies.
The company’s acquisition of MPNU has expanded its production and reserves profile, while its dual listing on the NGX and London Stock Exchange gives it exposure to both domestic and international investors.
The company’s performance also provides investors with exposure to Nigeria’s oil and gas sector through a locally controlled energy company.
For large institutional and strategic investors, Seplat’s scale makes changes in its market valuation particularly significant.
The bigger picture
Elumelu’s Seplat investment demonstrates how strategic corporate transactions can create substantial wealth when the underlying asset subsequently appreciates.
The $500 million acquisition in December 2025 has evolved into a stake currently valued at approximately $1.28 billion, based on Seplat’s September 1 closing price.
While the increase remains an unrealised market gain, it represents a substantial expansion in the value of one of the Heirs Group’s most prominent listed investments.
With Seplat shares now trading above N12,000, the key question for investors is whether the company’s earnings, cash flows and enlarged asset base can continue to support the valuation that the market has assigned to it.
