Seplat Energy has become one of the biggest stories on the Nigerian Exchange in 2026, with its share price rising sharply alongside stronger production, higher revenue and a significant expansion of the company’s asset base.
At the centre of the story is Tony Elumelu, whose Heirs Energies acquired a 20.07% stake in Seplat Energy for approximately $500 million in December 2025. The stake represents about 120.4 million shares previously held by French energy company Maurel & Prom.
If you’ve been following our coverage of the Dangote Refinery IPO and how Nigerian investors can apply, Seplat is another important Nigerian capital-markets story worth understanding.
But the most useful question is not simply how much Tony Elumelu’s stake is worth. It is why Seplat’s value has risen so sharply, what has changed in the underlying business, and what everyday investors can actually learn from the investment.
Key Takeaway: Heirs Energies acquired 20.07% of Seplat Energy, representing approximately 120.4 million shares, from Maurel & Prom for about $500 million in December 2025. Since then, Seplat’s share price has risen substantially as the company delivered stronger production and financial results. The lesson for everyday investors is not to copy Tony Elumelu’s investment, but to understand the business fundamentals behind it.
The Confirmed Numbers Behind Tony Elumelu’s Seplat Stake
| Detail | What Is Confirmed |

How Much Is Tony Elumelu’s Seplat Stake Worth?
The answer depends on the date because Seplat Energy is publicly traded and its market price changes every trading day.
On September 1, 2026, Seplat closed at ₦12,320.60 per share. At that price, the approximately 120.4 million shares were worth about ₦1.484 trillion, or roughly US$1.28 billion using the exchange-rate calculation reported at the time.
However, that figure should not be presented as the current value indefinitely.
NGX market data shows Seplat at ₦14,907.80 per share on September 10, 2026. At that price, the same 120.4 million shares would have a market value of approximately ₦1.795 trillion.
That is the estimated market value of the shares, not realised cash profit.
If Heirs Energies has not sold the shares, the increase represents an unrealised change in market value rather than money that has already been collected as profit.
How Is the Seplat Stake Value Calculated?
The calculation is straightforward:
120.4 million shares × Seplat share price = estimated market value of the stake.
Using the September 10, 2026 NGX price of ₦14,907.80:
120,400,000 × ₦14,907.80 ≈ ₦1.795 trillion.
Because the share price changes, this valuation will also change whenever Seplat trades.

How Seplat Became Nigeria’s First ₦10,000-Per-Share Stock
Seplat made Nigerian stock-market history in April 2026 when it became the first NGX-listed company to close above ₦10,000 per share.
The milestone attracted enormous attention, but it would be misleading to suggest that the share-price increase happened simply because Tony Elumelu bought a large stake.
The more important story is that Seplat itself had become a substantially larger company, with much higher production and revenue following the expansion of its upstream asset base.
A major shareholder can attract attention to a company, but a sustained market re-rating generally requires investors to believe that the underlying business can generate stronger earnings and cash flow in the future.
Why Has Seplat Energy’s Share Price Risen So Sharply?
Several factors help explain Seplat’s rise. Four are particularly important.
1. Seplat Became a Much Larger Energy Company
One of the most important changes was Seplat’s acquisition of ExxonMobil’s Nigerian upstream business, which significantly expanded the company’s production base and offshore exposure.
The effect became particularly visible in Seplat’s 2025 financial results.
Average working-interest production rose to 131,506 barrels of oil equivalent per day, compared with 52,947 boepd in 2024.
Revenue increased to approximately US$2.73 billion, up 144.2% from the previous year, while profit before tax increased 86.7% to approximately US$497.8 million.
Those numbers provide an important fundamental explanation for the market’s changing view of Seplat.
2. Seplat’s Financial Performance Remained Strong in 2026
The company’s first-half 2026 results provide an even more current picture.
For the six months ended June 30, 2026, Seplat reported revenue of approximately US$1.82 billion, up 30% year on year.
Adjusted EBITDA increased 28% to approximately US$938.6 million, while profit after tax rose to approximately US$164 million, compared with US$27.4 million in the first half of 2025.
Production averaged approximately 139,509 boepd, up 4% year on year.
These numbers matter because the share-price story is being accompanied by significant growth in the underlying business.
See Seplat Energy’s official financial results and investor presentations.
3. Higher Oil Prices and Stronger Cash Generation Helped
Seplat’s first-half 2026 results also benefited from a stronger commodity-price environment.
The company reported an average realised oil price of approximately US$94.13 per barrel during the first half of 2026, compared with US$72.58 per barrel during the same period in 2025.
Cash generated from operations increased to approximately US$985.9 million, while net debt fell to approximately US$370.7 million at the end of June 2026, down from US$673.3 million at the end of 2025.
That combination is important: stronger commodity prices supported revenue and cash generation while the company was also reducing its net debt.
4. Nigeria’s Return to the FTSE Russell Frontier Market Is Another Factor
Nigeria is scheduled to return to FTSE Russell’s Frontier Market classification from the opening of trading on September 21, 2026.
The reclassification is significant because it increases the visibility of Nigerian equities among international investors and could improve market participation and liquidity.
However, investors should be careful about treating projected foreign inflows as guaranteed money flowing into Seplat. Actual investment flows will depend on index composition, investor positioning, market accessibility and wider global market conditions.
Did Tony Elumelu’s Investment Cause Seplat’s Share Price to Rise?
There is an important distinction here.
It is reasonable to say that Elumelu’s investment increased attention around Seplat. It is much harder to prove that the acquisition itself caused the subsequent share-price increase.
Seplat’s own financial performance, production growth, commodity prices, debt reduction, expectations around its expanded asset base and changing investor sentiment all provide potential explanations for the re-rating.
That is why I would avoid describing the entire move as an “Elumelu effect” unless there is specific evidence showing how much of the price increase can actually be attributed to his involvement.
Is Tony Elumelu Already Chairman of Seplat?
No.
Tony Elumelu is currently a Non-Executive Director of Seplat Energy.
He was appointed to the company’s board in January 2026. Seplat has announced a leadership transition under which Elumelu is scheduled to become Chairman of the Board on January 1, 2027.
That distinction matters because some reports may discuss the planned transition while others refer to his current board position.
What Could Go Wrong for Seplat Investors?
A rising share price does not eliminate the risks of owning an oil and gas company.
Seplat remains exposed to international oil and gas prices, production interruptions, infrastructure problems, regulatory developments, operational risks and the broader Nigerian business environment.
Production can also be affected by events outside the company’s direct control. That means investors should not assume that a strong production figure from one reporting period will automatically continue forever.
There is also valuation risk.
When a stock rises sharply, investors can begin pricing in increasingly optimistic expectations for future earnings and production. If those expectations are not met, the share price can fall even when the company remains profitable.
This is one reason why looking only at the percentage increase in a stock price is not enough. Investors also need to examine the valuation being placed on the underlying business.
What Tony Elumelu’s Seplat Investment Teaches Everyday Investors
The most useful lesson is not “buy what rich people buy.”
A transaction of this size can involve extensive financial, legal, technical and commercial due diligence that an individual retail investor cannot easily replicate.
What ordinary investors can copy is the research process, not the transaction itself.
Before buying a Nigerian stock because a prominent investor owns it, look at the company’s own financial disclosures. Compare:
- Revenue growth
- Profit growth
- Production or sales growth
- Debt and cash flow
- Dividend history
- Asset growth
- Industry and commodity risks
- Current valuation
Then ask a harder question:
Is the company’s underlying business becoming more valuable, or is the share price simply rising because investors have become more optimistic?
That distinction is one of the most important habits an investor can develop.

The Bottom Line
Tony Elumelu’s Seplat investment is one of the more interesting Nigerian capital-markets stories of 2026, but the headline number only tells part of the story.
Heirs Energies paid approximately US$500 million for a 20.07% stake in Seplat in December 2025. Since then, Seplat’s share price has risen substantially, increasing the market value of that holding.
But the company’s performance cannot be reduced to the identity of one shareholder.
Seplat has become a significantly larger business, reported strong financial growth, increased production, generated substantial cash and reduced net debt. At the same time, investors are responding to changing expectations around Nigerian equities and the country’s return to FTSE Russell’s Frontier Market classification.
For ordinary investors, the more valuable lesson is therefore not to copy Tony Elumelu’s purchase. It is to understand why the investment was made, what changed in the underlying business, what risks remain, and whether the current share price already reflects those expectations.
