Heirs Holdings’ investment in Seplat Energy has more than doubled in value in less than eight months, as the energy company’s surging share price pushes the Nigerian investment vehicle’s 20.07% stake above the $1 billion mark.
Seplat Energy Plc, Nigeria’s leading indigenous energy company, has seen its market capitalisation rise to about $5.24 billion, as investors continue to reprice the company following its transformational acquisition of Mobil Producing Nigeria Unlimited (MPNU).
At Seplat’s current share price of N11,200.60 on the Nigerian Exchange and £6.47 on the London Stock Exchange, the 120.4 million shares held by Heirs Holdings are now valued at roughly $1 billion, compared with the approximately $500 million the investment vehicle paid for the stake in December 2025.
The gain represents a striking turnaround for an investment that was initially viewed primarily as a strategic bet on Seplat’s enlarged asset base following the MPNU acquisition.
Heirs Holdings, the investment company founded by Nigerian billionaire and Africapitalism advocate Tony Elumelu, became Seplat’s largest shareholder in December 2025 after acquiring the 20.07% stake from French energy company Maurel & Prom.
The transaction was significant not only because it altered Seplat’s shareholder structure, but also because it came shortly after Seplat completed one of the most consequential transactions in Nigeria’s oil and gas industry—the acquisition of MPNU from ExxonMobil.
The market’s response was swift.
Within the first trading week of 2026, Seplat’s share price gained 6.2%, reaching a new 52-week high as investors appeared to interpret the Heirs transaction as a strong vote of confidence in the company’s strategy and significantly expanded production base.
The rally, however, did not end there.
From N5,809 at the end of 2025, Seplat’s shares climbed above N9,000 by March 2026. In April, the stock became the first company listed on the Nigerian Exchange to cross the N10,000-per-share threshold, closing at N10,450 on April 14 and recording a year-to-date gain of almost 80%.
The shares have since traded above N11,000, leaving the stock up by more than 90% from its end-2025 level.
For Heirs Holdings, the appreciation has translated into a dramatic increase in the value of its Seplat investment.
The 120.4 million shares acquired for approximately $500 million are now worth more than $1 billion at prevailing market prices, effectively doubling the value of the investment in less than eight months.
Fundamentals behind the rerating
While the share-price performance has been spectacular, Seplat’s underlying financial performance provides an important part of the explanation for the market’s enthusiasm.
The MPNU acquisition fundamentally changed the scale and composition of Seplat’s business, transforming it from a predominantly onshore producer into a much larger integrated energy company with substantial offshore operations.
The impact became evident in the company’s 2025 financial performance, its first full year reflecting the enlarged business.
Revenue surged 144% to $2.73 billion, while adjusted EBITDA rose 137% to $1.28 billion. Operating cash flow increased by 276% to $1.17 billion, while net debt declined by 25% to $673.3 million.
Seplat also increased its total dividend for 2025 by 52% to 25 cents per share, strengthening the investment case for shareholders seeking both capital appreciation and income.
The momentum has continued into 2026.
In the first half of the year, Seplat generated N2.50 trillion in revenue, but the more significant development was the improvement in profitability.
Profit before tax rose 74% to N790.4 billion, while profit after tax increased sharply from N42.5 billion in the corresponding period of the previous year to N225.5 billion.
At the same time, Seplat continued to strengthen its balance sheet.
Interest-bearing borrowings fell from approximately N1.44 trillion at the end of 2025 to N1.11 trillion by June, while cash and cash equivalents increased to N598.3 billion.
The combination of higher earnings, stronger cash generation and declining leverage has provided investors with greater confidence that the company’s enlarged asset base is translating into sustainable financial performance.
Production scale changes the story
The transformation is equally evident in Seplat’s production profile.
Average working-interest production reached 139,509 barrels of oil equivalent per day (boepd) in the first half of 2026, compared with 134,492 boepd in the same period of 2025.
Offshore assets accounted for more than half of total production, while natural gas liquids production more than doubled to 8,459 barrels per day.
The significance extends beyond the headline production increase.
Seplat now has a more diversified production and earnings base, reducing its reliance on the narrower production profile that characterised the company before the MPNU acquisition.
The change was already visible in 2025, when average production rose to 131,506 boepd from 52,947 boepd in 2024 following the consolidation of the offshore assets.
The enlarged portfolio gives Seplat greater scale and potentially greater resilience, while providing a larger platform from which management can pursue further production growth and operational efficiencies.
Elumelu factor
Tony Elumelu’s increasing involvement in Seplat adds another dimension to the company’s outlook.
Elumelu joined Seplat’s board in January 2026 and is expected to become chairman from January 1, 2027.
That would create a closer alignment between Seplat’s largest shareholder and its corporate leadership at a critical stage in the company’s development.
Elumelu’s presence also gives the investment a strategic dimension beyond the immediate market value of the shares. His investment philosophy has historically focused on building African businesses capable of generating long-term economic value, with major interests including United Bank for Africa and Transcorp.
For Seplat, the combination of a dramatically enlarged asset base, improved earnings, stronger cash generation and a major long-term Nigerian investor could reinforce expectations of continued expansion.
Market optimism faces the execution test
Despite the impressive performance, the doubling of Heirs Holdings’ investment value should not be interpreted as a guaranteed return.
The current valuation reflects significant investor expectations about Seplat’s ability to sustain production, manage operating costs, maintain strong cash flows and continue reducing leverage.
The company must also demonstrate that the benefits of the MPNU acquisition can be sustained beyond the initial post-acquisition boost.
Oil prices, production disruptions, crude theft, regulatory risks, foreign-exchange movements and the broader operating environment in Nigeria’s oil and gas industry remain important variables.
For investors, therefore, the next phase of Seplat’s story will be less about proving that the MPNU acquisition has transformed the company and more about demonstrating that the enlarged business can consistently generate returns commensurate with its substantially higher market valuation.
For Heirs Holdings, however, the numbers already tell a remarkable story.
An investment of approximately $500 million made in December 2025 has, on current market prices, grown to more than $1 billion in less than eight months.
That appreciation is ultimately a reflection of how dramatically market expectations have changed around Seplat.
More importantly, the company’s stronger earnings, rising production, improved cash generation and declining debt suggest that the stock’s rerating is not being driven by sentiment alone.
The real test now is whether Seplat can convert the transformational scale created by MPNU into sustained production growth, stronger cash flows and long-term shareholder value.
