Seplat Energy Plc has agreed to transfer a 10% working interest in its offshore joint venture with Nigerian National Petroleum Company Limited for approximately $281.6 million, reducing its economic exposure to some of Nigeria’s major shallow-water oil and gas assets while retaining operatorship.
Under the agreement announced by Seplat, NNPC’s participating interest in the NNPC-Seplat Energy Producing Nigeria Unlimited joint venture will rise from 60% to 70%, while SEPNU’s interest will fall from 40% to 30%.
The ownership change does not mean Seplat is surrendering control of day-to-day operations. SEPNU will remain operator of the joint venture, while Seplat will continue to own 100% of SEPNU.
That distinction is central to the deal.
Seplat is effectively monetising part of an asset it acquired less than two years ago while retaining responsibility for operating and developing the fields. It plans to direct roughly half of the transaction proceeds towards debt reduction and the remainder to shareholders.
The agreement remains subject to regulatory approvals and customary completion conditions, with closing expected in the second half of 2026.
Why Is Seplat Selling 10% of Its Biggest Offshore Asset?
The transaction did not come as a surprise.
Seplat told investors at its September 2025 Capital Markets Day that it was discussing a potential 10% sell-down to NNPC. At the time, the company said a completed deal would leave SEPNU with 30%, NNPC with 70%, and Seplat as operator.
Seplat was still describing the talks as ongoing when it released its first-quarter 2026 results in April, saying no agreement had yet been reached.
The transaction therefore represents the completion of a capital-allocation strategy that management had been signalling for months.
Before the deal, NNPC held 60% and SEPNU 40% in assets, including OMLs 67, 68, 70 and 104. NUPRC’s June 2026 concession report still listed that 60:40 equity structure, with SEPNU as operator.
Once the transaction closes, NNPC will have a larger economic interest in those assets, but the operating structure will remain largely unchanged.
How Much of Its ExxonMobil Acquisition Is Seplat Recovering?
The $281.6 million consideration is significant because it allows Seplat to recover part of the capital committed to its transformative acquisition of ExxonMobil’s Nigerian shallow-water business.
Seplat completed the acquisition in December 2024 and renamed Mobil Producing Nigeria Unlimited as Seplat Energy Producing Nigeria Unlimited.
At completion, Seplat reported cash consideration of $800 million, including a $128.3 million deposit previously paid. The agreement also provided for contingent consideration tied to production and oil-price conditions.
The original 2022 agreement had contemplated $1.283 billion in consideration plus up to $300 million of contingent payments before later adjustments ahead of completion.
The company says the $281.6 million price for the 10% interest represents approximately 25% of the gross acquisition price, including contingent consideration.
But this is not simply Seplat reversing part of the ExxonMobil transaction.
When Seplat bought the business, it acquired the company that owned the 40% working interest and became operator of a major offshore portfolio. Selling one-quarter of that 40% interest still leaves Seplat exposed to 30% of the underlying joint venture and, importantly, leaves the company in the operator’s seat.
That gives Seplat a way to release capital without walking away from the offshore growth strategy that drove the acquisition in the first place.
Why Keep Operatorship After Reducing the Stake?
Operatorship can matter as much as percentage ownership in an upstream joint venture.
The operator manages field development, production activity, maintenance programmes and execution of agreed work plans, although major investment decisions still depend on the partnership and regulatory framework.
For Seplat, retaining that role protects the operational strategy it has been building since taking over the former ExxonMobil assets.
The company previously said the acquisition significantly expanded its offshore production and reserves. By the first half of 2025, offshore production contributed 79,660 barrels of oil equivalent per day to Seplat, compared with a group total of 134,492 boepd.
Seplat subsequently built much of its 2030 growth plan around extracting more production from that enlarged asset base through well restoration, new drilling, maintenance and gas developments.
That strategy remains intact even with a lower working interest.
The difference is that Seplat will now receive a smaller share of production and cash flow while also carrying a smaller share of future capital requirements.
Where Will the $281.6m Go?
The immediate attraction for shareholders lies in what Seplat intends to do with the money.
The company says approximately 50% will support debt reduction and 50% will go towards enhanced shareholder returns.
Subject to completion, about $140 million, equivalent to 23.3 US cents per share, is expected to be distributed as a transaction dividend, separate from dividends generated by the underlying business.
Debt reduction forms the other side of the equation.
Seplat is targeting up to $300 million in gross debt repayment during 2026. It says $200 million of its Advanced Payment Facility was repaid during the second quarter, while another $100 million is expected to be repaid after the transaction closes.
That follows an already visible deleveraging trend.
Seplat reported net debt of $531.6 million at the end of the first quarter of 2026, down 21% from $673.3 million at the end of 2025. Free cash flow reached $199.2 million during the quarter.
The sell-down therefore gives management another source of cash without requiring new equity or giving up operatorship.
What Does Seplat Give Up in Return?
There is a real cost.
A lower working interest means less production, fewer reserves attributable to Seplat and a smaller share of future cash flows from the offshore joint venture.
Seplat says SEPNU currently accounts for about 80,000 boepd at the midpoint of its 2026 group production guidance of 135,000 to 155,000 boepd.
On a pro forma basis using an April 1 effective date, the contribution would fall to around 65,000 boepd once the 10% transfer is reflected.
The company’s 2030 production ambition also falls.
Seplat had previously targeted approximately 200,000 boepd by 2030. Its 2025 Capital Markets Day presentation had already shown that a 10% sell-down could reduce that target to roughly 170,000 boepd.
Its 2P reserves would also decline. According to the announcement supplied, Seplat estimates a roughly 13% reduction to 872.9 million barrels of oil equivalent after completion.
So this is not free cash.
Seplat is exchanging part of its long-term production and reserve base for immediate liquidity, a lower capital burden, reduced leverage and higher distributions to investors.
Does the Deal Weaken Seplat’s $1bn Shareholder Return Plan?
Management argues that it does not.
Seplat’s capital-allocation framework targets distributing 40% to 50% of free cash flow between 2026 and 2030, with at least $1 billion in cumulative shareholder distributions over the period.
Its 2026 plan already included a minimum annual distribution of $120 million and an initial production target of 135,000 to 155,000 boepd.
Seplat had also told investors as far back as September 2025 that its dividend policy would remain unchanged if the NNPC transaction proceeded.
The economic argument is that the cash received now, combined with lower future capital expenditure on the 10% interest sold, should largely compensate for the lower share of future joint-venture cash flow through 2030.
Whether that assumption holds will depend on production growth, oil and gas prices, project execution and the amount of capital required to develop the offshore portfolio.
What Does NNPC Gain?
For NNPC, the deal raises its exposure to a strategically important group of Nigerian offshore assets from 60% to 70%.
The assets include established producing fields, export infrastructure and large oil and gas resources. They are also increasingly important to Seplat’s offshore gas strategy.
In July, the NNPC-SEPNU joint venture signed a 15-year agreement to supply 200 million standard cubic feet of gas per day to UTM Offshore’s proposed floating LNG project from the Yoho field.
A larger participating interest therefore gives NNPC a greater economic share of production and future development from a portfolio it already majority owns.
Seplat, however, retains the operational platform.
That makes the transaction unusual in an important way: NNPC gets more of the economics, while Seplat keeps running the assets.
The Bigger Question Is Whether Seplat Is Selling at the Right Time
The $281.6 million deal strengthens Seplat’s balance sheet and creates room for an unusually large cash return to shareholders.
It also reduces the company’s exposure to future offshore capital spending while preserving its role as operator.
But those benefits come with a measurable trade-off: lower attributable production, lower reserves and a 2030 production target reduced from around 200,000 to 170,000 boepd.
For investors, the key question is therefore not whether Seplat received $281.6 million.
It is whether the cash released today, the debt eliminated and the capital expenditure avoided ultimately create more value than the 10% interest Seplat is giving up.
That calculation will become clearer only as the offshore development programme moves forward.
