A prospective $39bn valuation for Dangote’s refinery and an eventual NNPC flotation could transform Africa’s capital markets. But before Nigeria can turn barrels into shares, it must convince investors that political risk, opaque accounts and concentrated market power deserve something other than a discount.

JOHANNESBURG — Nigeria is preparing an experiment that could reshape African capital markets: turning two of the continent’s most important energy businesses into publicly priced assets.

One is the state-owned NNPC Ltd, which reported N45.1tn of revenue and N5.4tn of profit after tax for 2024, roughly $33.2bn and $4bn, respectively, at an exchange rate of about N1,360 to the dollar, and has outlined a $60bn investment programme through 2030. The other is the Dangote Petroleum Refinery, a 650,000-barrel-a-day complex that cost more than $20bn to build and is now being pitched to private investors at a valuation of approximately $39.1bn.

Put differently, the private-market valuation being sought for Dangote is almost twice its construction cost, larger than NNPC’s reported 2024 dollar revenue and equivalent to roughly one-third of the Nigerian equity market’s capitalisation at early-June exchange rates. That is why this is about considerably more than two IPOs.

Nigeria is attempting to answer a question that has haunted resource-rich African economies for decades: can petroleum wealth be transformed from an instrument of state power and private concentration into transparent, tradable and productive financial capital?

The answer will depend less on how many shares are sold than on what investors discover underneath them, a stock exchange does not turn opacity into value. It merely puts a price on it.

The $39bn test

The Dangote valuation provides the first serious indication of the scale involved, in June, the refinery sought roughly $1bn through a private placement, offering 3bn ordinary shares at $0.35 each. The transaction implied a valuation of about $39.1bn, while reported indications of investor demand exceeded $2bn. The shares were subject to a 365-day lock-up, with proceeds intended for expansion and general corporate purposes.

At $39.1bn, even a relatively modest public float would be enormous by Nigerian standards.

If the eventual IPO were priced around that valuation, a 10% float would represent $3.9bn; 15% would be approximately $5.9bn; and 20% would amount to $7.8bn.

Those are not forecasts of the eventual offering. They illustrate its potential scale.

Nigeria’s equity market was capitalised at about N155.6tn in early June, or approximately $114bn-$115bn at N1,360 to the dollar. A $39.1bn Dangote valuation would therefore be equivalent to roughly one-third of the value of the entire Nigerian stock market at that exchange rate.

That comparison changes the nature of the question.

The issue is no longer simply whether Dangote can list the refinery. It is whether Lagos can absorb it.

Who buys $5bn of Nigerian refining risk?

Nigeria has pools of domestic capital, but they are not unlimited, pension assets stood at roughly N29.5tn, and the pension regulator has created an exception allowing pension fund administrators to participate in the proposed Dangote offering despite rules that would ordinarily restrict investment in companies without an established record of profitability and dividends. At N1,360 per dollar, N29.5tn is approximately $21.7bn.

A hypothetical $5bn Dangote offering would therefore be equivalent to almost 23% of the entire Nigerian pension asset pool. Pension funds would obviously invest only a fraction of their assets in a single security, which means a transaction of that magnitude would almost certainly require a much broader coalition of domestic institutions, wealthy individuals, African investors and international emerging-market funds.

This helps explain the attraction of Johannesburg.

The Johannesburg Stock Exchange said in August that Dangote had demonstrated a “strong intent” to pursue a South African listing following the Nigerian IPO. A secondary JSE quotation would not merely provide prestige. It could expand access to a deeper institutional investor base and create an African price-discovery mechanism spanning the continent’s two most important equity-market ecosystems.

The refinery could, in effect, become a test of whether African savings can finance African industrialisation at scale.

But first investors must decide whether $39.1bn is a price or a valuation, the distinction matters.

Construction cost is not equity value

Dangote’s refinery cost more than $20bn to build. That does not mean its equity is worth $20bn, or $39bn.

Investors will ultimately have to work from a more prosaic equation, Equity value = enterprise value minus net debt.

The refinery’s economics will therefore depend on information that becomes indispensable in a public offering: EBITDA, net debt, interest expense, utilisation, refining margins, working-capital requirements, crude procurement costs, petrochemical earnings, foreign-exchange exposure and future capital expenditure.

Until audited IPO documentation provides those numbers in sufficient detail, a precise public-market fair value would be false precision, it is nevertheless possible to demonstrate the sensitivity.

At a $39.1bn equity valuation, an annual EBITDA of $4bn would imply an equity-value-to-EBITDA ratio approaching 9.8 times before accounting properly for net debt and other valuation adjustments. At $5bn of EBITDA, it falls to about 7.8 times; at $6bn, about 6.5 times, the market will therefore not merely be buying a refinery.

It will be buying assumptions about utilisation, margins, crude availability and the ability to maintain them through a commodity cycle, that is a much harder proposition.

One dollar a barrel can become hundreds of millions

Few numbers illustrate the sensitivity better than crude procurement.

Nigeria is considering changes intended to make crude supply to domestic refiners cheaper and more direct after refiners complained that intermediary costs could add roughly $3-$4 a barrel to feedstock. Regulatory compliance with domestic crude-supply obligations has meanwhile improved sharply, for a 650,000-b/d refinery, the mathematics becomes material very quickly.

At full nameplate utilisation, $1 per barrel represents about $237mn a year. A $3 differential is approximately $712mn. At $4, the theoretical annual impact approaches $950mn.

That is nearly $1bn generated not by a change in refining technology or capacity, but by the mechanics of obtaining crude.

This is why Dangote cannot be analysed independently of NNPC and the Nigerian state.

The refinery may be privately controlled, but its economics sit inside a petroleum system in which government policy, crude allocation, foreign exchange, infrastructure access, import competition and regulation remain enormously consequential, that creates what investors might call the Nigeria discount.

The Nigeria discount

Every emerging-market asset carries a risk premium. Nigeria’s can be broken into at least four components, the first is currency risk.

The naira was trading at about N1,360 to the dollar in the official market in early August, after several years of profound adjustment. For a foreign shareholder, a 30% rise in a Nigerian stock does not constitute a 30% return if the currency loses a substantial proportion of its value against the dollar during the same period.

The second is interest-rate risk.

The Central Bank of Nigeria retained its monetary policy rate at 26.5% in July 2026. That means equities are competing for domestic savings against extraordinarily high nominal fixed-income yields. A refinery IPO must therefore offer investors sufficient expected returns to compensate not only for corporate risk but also for the opportunity cost of holding Nigerian bonds and bills.

The third is regulatory risk.

Fuel pricing, imports, crude supply, taxes, foreign exchange and competition policy can all materially alter refinery economics.

The fourth, and potentially most expensive, is governance risk.

Investors must know whether related-party transactions occur at arm’s length; how independent directors are appointed; how minority shareholders are protected; what dividend policy applies; and whether controlling shareholders can shift value between affiliated companies, the better the answers, the smaller the discount, that principle applies even more forcefully to NNPC.

NNPC’s problem is not size. It is legibility

NNPC is already a commercial company in law, Nigeria’s Petroleum Industry Act of 2021 established the framework for transforming the old Nigerian National Petroleum Corporation, and NNPC Ltd formally began operating under its new corporate structure in 2022, he difficult part comes next.

Its 2024 results show the scale of the enterprise: N45.1tn in revenue, up 88%, and N5.4tn in profit after tax. NNPC has also announced a $60bn investment pipeline through 2030 across the energy value chain.

But public investors require more than profitability.

They require legibility. Before an IPO, investors would need to understand legacy liabilities, tax and royalty obligations, receivables from government entities, pipeline losses, refinery exposures, subsidiaries, joint ventures, financing commitments and the boundary between commercial expenditure and national energy policy.

That last distinction is particularly important. NNPC is expected to behave like a company while simultaneously serving as an instrument of the Nigerian state. It has responsibilities connected to energy security, crude production, gas development and national strategic objectives.

Those roles are not necessarily incompatible with public ownership.

But they have a price.

Petrobras shows what Nigeria could gain, and risk

Brazil provides perhaps the most instructive comparison.

Petrobras remains under state control while having a substantial privately held shareholder base and internationally traded securities. As of June 2026, its controlling group held 36.26% of total capital, while its reported free float represented 63.74%. Foreign investors alone accounted for more than 48% of total capital.

That structure demonstrates something important for Nigeria: government control and deep public-market participation are not mutually exclusive, it also demonstrates the danger.

A state-controlled petroleum company can trade at a governance discount whenever investors fear that fuel pricing, dividends, capital expenditure or management decisions will be subordinated to political priorities.

NNPC’s eventual valuation would therefore depend partly on whether investors believe Abuja can be an owner without behaving as the day-to-day manager.

Saudi Arabia provides another model. The Saudi government continues to own more than 81.48% of Saudi Aramco, demonstrating that even a limited free float can establish a public price for an enormous national petroleum asset.

Colombia’s Ecopetrol offers another version: a state-controlled oil company with minority investors and international market exposure, but one whose valuation remains sensitive to changes in national energy and fiscal policy, the lesson is not that Nigeria should copy Brazil, Saudi Arabia or Colombia.

It is that listing a national oil company does not remove politics from its valuation. It gives politics a market price.

NNPC and Dangote are not two separate IPO stories

This may be the most important point, the potential NNPC and Dangote listings are often treated as parallel capital-market events. Economically, they are intertwined.

NNPC acquired a minority interest in the Dangote refinery after initially seeking a much larger stake. That makes the state oil company simultaneously part of the petroleum supply system, a strategic actor in domestic crude markets and an investor in the country’s dominant refinery.

A public valuation for Dangote would consequently do something else: establish a transparent market reference for an important asset connected to NNPC.

At a $39.1bn valuation, every percentage point of Dangote equity corresponds arithmetically to roughly $391mn.

A 7.2% interest, if valued mechanically at the same headline equity valuation and before applying any minority, liquidity, contractual or other adjustments, would correspond to about $2.8bn.

That does not mean the stake could necessarily be sold for $2.8bn. It demonstrates why price discovery matters.

An IPO would begin turning opaque strategic relationships into markable financial assets.

For NNPC, that could be transformative.

Nigeria must avoid replacing one monopoly with another

There is, however, a second valuation problem: market power.

Dangote is not merely another refinery competing in an established market. At 650,000 b/d, it is an industrial asset large enough to reshape Nigeria’s fuel-import requirements, domestic distribution and potentially West African petroleum trade, that scale creates efficiencies.

It also creates concentration, Nigeria should not have to choose between an inefficient state monopoly and an efficient private one.

A credible downstream market requires contestability: transparent import rules, non-discriminatory infrastructure access, clear storage and terminal arrangements and competition enforcement capable of distinguishing industrial scale from abuse of dominance, the answer is not administrative price fixing, it is making the market observable.

Regular disclosure of refinery-gate prices, import-parity costs, freight, taxes, crude costs, available volumes and terminal utilisation would allow regulators and investors to distinguish changes in underlying economics from exercises of market power.

Data transparency is competition policy in practical form.

A $39bn refinery could become a continental benchmark

The significance extends beyond Nigeria, at the private-placement valuation of $39.1bn, Dangote would represent one of the most valuable industrial assets ever brought towards African public markets.

A successful Lagos listing followed by Johannesburg could establish something Africa has long lacked: a market-derived valuation benchmark for very large privately developed infrastructure.

That could affect how investors think about ports, railways, power generation, mining infrastructure, fertiliser complexes and other capital-intensive African assets.

More importantly, it could alter the financing model.

Africa has historically relied heavily on governments, development-finance institutions, international banks and foreign strategic investors to finance infrastructure. Dangote raises the possibility that an African industrial asset can be built privately, scaled regionally and then partially recycled into African public capital markets, that is potentially revolutionary, but only if the valuation survives public scrutiny.

The numbers investors should demand

The prospectus will therefore matter more than the ceremony surrounding the IPO. For Dangote, investors should focus on five numbers above all: EBITDA, net debt, utilisation, free cash flow and sustaining capital expenditure.

For NNPC, another five become critical: free cash flow, net debt, government receivables and obligations, upstream production economics and the value of non-core assets and subsidiaries.

Without them, headline revenue and profit provide scale but not necessarily value.

And for both companies, investors will need to know how much equity is genuinely available.

A $39bn company with a 5% free float is a very different security from a $39bn company with 20% freely traded. Liquidity affects institutional participation, index eligibility, price discovery and ultimately the valuation multiple investors are willing to pay, free float is therefore not a technical detail. It is part of corporate governance.

Abuja should resist the temptation to sell quickly

The Nigerian government faces an obvious temptation, asset sales can generate cash, but a government that urgently needs cash is structurally a weak seller.

If NNPC or other federal petroleum holdings are brought to market primarily to fill fiscal gaps, investors will know that the seller has a deadline. That weakens negotiating power and increases the probability that valuable assets are sold below their long-term worth.

Nigeria would be better served by a multi-year privatisation framework establishing in advance which assets can be sold, maximum and minimum stakes, valuation procedures, use of proceeds and rules governing state control.

Proceeds should also be treated as capital rather than ordinary revenue.

Selling a petroleum asset to finance recurrent expenditure merely exchanges an income-producing asset for consumption.

Using privatisation proceeds to reduce expensive debt or finance productive infrastructure changes the sovereign balance sheet. That is a much more defensible transaction.

From barrels to shares

Nigeria’s great opportunity is that three reforms that spent decades moving on separate tracks are finally converging.

The first is energy-market reform, including subsidy removal and greater market pricing.

The second is state-enterprise reform, centred on turning NNPC from a government corporation into a commercially accountable company.

The third is capital-market reform, through which Nigeria is attempting to mobilise domestic and international savings for productive investment. Dangote sits at the intersection of all three, so does NNPC.

The numbers show what is at stake. Dangote is seeking a private-market valuation of about $39.1bn. NNPC generated N45.1tn, roughly $33bn, in 2024 revenue and has outlined $60bn of investment through 2030. Nigeria’s equity market was worth roughly $115bn in early June at prevailing exchange rates. Pension assets amount to about $22bn on the same broad currency basis, the scale is extraordinary.

But size is not the same thing as investibility. The decisive question is whether Nigeria can reduce the discount investors attach to political intervention, currency volatility, regulatory unpredictability, concentrated ownership and opaque financial relationships.

If it can, the NNPC and Dangote listings could do something more consequential than create two enormous quoted companies.

They could begin transforming Nigerian petroleum wealth from an underground reserve into a financial asset that millions of pensioners, households and institutional investors can own. That would amount to a profound change in the political
