What the Dangote Refinery Actually Is, and Why Africa Keeps Buying Back Its Own Oil

Africa ships out roughly 2.6 billion barrels of crude oil a year and buys back roughly 1.4 billion barrels of refined fuel. It is a continent that sells wheat and imports bread. The Dangote refinery is the largest single attempt to change that — and its share offer is open until 27 October.

The thing itself

The Dangote Petroleum Refinery sits on a 6,180-acre site in the Lekki Free Trade Zone, outside Lagos, Nigeria. It is rated at 650,000 barrels per day and cost somewhere around $20 billion to build.¹² It is the largest refinery in Africa and one of the largest single-train refineries anywhere in the world.

It is also privately owned, by Aliko Dangote, which makes it unusual. Refineries at this scale are normally built by national oil companies or supermajors.

The timeline is worth seeing, because it explains why people doubted it for a decade:

• 2013 — about $3.3 billion of financing announced; project estimated at roughly $9 billion.
• 2016 — construction begins at the Lekki site.
• May 2023 — officially commissioned.
• December 2023 — first crude delivery, 1 million barrels of Nigerian Agbami.
• January 2024 — diesel and jet fuel production starts.
• September 2024 — petrol production starts.
• Early 2026 — reaches full rated capacity.¹

Ten years from financing to full capacity, and roughly double the original budget. That is normal for megaprojects and worth remembering when you read about the next one.

Why Africa buys back its own oil

Here is the paradox in four numbers, and it is the single most important thing to understand about this business.

The continent pumps crude, sells it cheaply as a raw commodity, and then pays a premium to buy it back as petrol, diesel and jet fuel after someone else has done the processing — usually in Europe, India or the Gulf.³

The gap is where the money goes. Refining margins have run roughly $10 to $25 a barrel. One analysis estimates that if Africa refined all the crude it currently exports, it would capture an extra $26 billion to $65 billion a year — somewhere between 0.9% and 2.2% of the continent's entire GDP.³

So why hasn't it happened? Capital. Refining all of Africa's exported crude would need about 7.1 million barrels per day of capacity and roughly $220 billion of investment.³ That is an enormous amount of money to commit to single, immovable assets in countries where policy and currency can shift quickly.

Nigeria is the clearest case. It is one of Africa's largest crude producers, and for years it imported nearly all of its petrol. Its three state-owned refineries — Port Harcourt, Warri and Kaduna — have consumed more than $2.4 billion of public money and produced almost nothing. Port Harcourt alone accumulated debts reported at ₦4.22 trillion. Both Port Harcourt and Warri restarted briefly in late 2024, then shut down again.⁴

That is the hole Dangote was built to fill.

What the share offer is actually funding

The company is selling 4.1 billion new shares at ₦525 each, raising about ₦2.15 trillion, or roughly $1.6 billion. That represents about 3.3% of the enlarged company.⁵⁶

Crucially, these are new shares. The money goes into the business rather than to the existing owner. It part-funds a $14.3 billion programme to roughly double capacity from 700,000 to 1.4 million barrels a day by 2029.⁵

At 1.4 million barrels a day, the refinery would be processing more crude than most countries consume, and would be positioned as an export hub for the whole region. It already ships to Ghana, Cameroon, Togo and Tanzania, with South Africa and Kenya reported to be seeking supply arrangements.¹

We wrote separately about what a 3.3% free float means for liquidity and index weight — it is a small slice, and small slices behave in specific ways.

The numbers it is bringing to the offer

The company published unaudited nine-month figures on 13 October, and they are the reason the offer has attracted attention.⁵

It ended September with $6.69 billion of cash and a net cash position of $650.8 million, against net debt of $1.73 billion a year earlier. That is a dramatic turn in twelve months.

One figure deserves a closer look. The gross refining margin in the first half was $24.50 per barrel, against $13.70 in 2025.⁵ That is near the top of the historical $10–$25 range — and refining margins are cyclical, not permanent. Part of 2026's strength reflects an unusually disrupted year for global fuel supply, including the Strait of Hormuz disruption. A profit built partly on an exceptional margin environment should be read as an exceptional year, not a new baseline.

How the offer is being allocated

The offer opened on 14 September, was due to close on 13 October, and has been extended to 27 October with approval from Nigeria's Securities and Exchange Commission.⁵⁶ Listing on the Nigerian Exchange is expected around late November or December; the date is not yet fixed, and published sources disagree on the month.⁷

Two details matter for small applicants:

• Small applications get priority. Dangote has said that if the offer is oversubscribed, applications of ₦50,000 or less will be served first — at ₦525 a share, that is 95 shares. The minimum application is 10 shares, or ₦5,250. His stated aim is that "ordinary Nigerians are not crowded out by large subscriptions." How the priority works mechanically has not been published.⁶
• A matching programme for some buyers. The Aliko Dangote Foundation is running a ₦40 billion scheme matching share for share: eligible tertiary students and vulnerable women who buy the minimum 10 shares receive 10 free shares, up to 5 million students and 2 million women.⁶

Reported subscription figures should be treated carefully. One widely cited tracker says about ₦1.5 trillion was subscribed in the first hour, but flags it as unverified, and no official final subscription total or applicant count has been published.⁷ Be sceptical of precise oversubscription multiples circulating online; a 3.7× figure in circulation refers to a private placement in July 2026, not this public offer.⁷

What could go wrong

This is the part the promotional coverage tends to skip, and it is the part worth your attention.

Nigeria still imports a lot of petrol. In August 2026 the country took in 50.5 million litres a day. Domestic supply — almost all of it Dangote — was 35.9 million litres. Imports were 14.6 million litres a day, close to three litres in every ten.⁸ The refinery dominates, but it has not displaced imports.

The courts are keeping the import door open. On 28 September 2026, Justice Inyang Ekwo of the Federal High Court in Abuja ruled for three fuel marketers against the regulator, ordering it to continue granting and renewing their import licences, and holding that the law requires a competitive fuel market and prevents abuse of a dominant position.⁸ Dangote's own separate suit seeking to curb import licences, filed in May 2026 in Lagos, is still pending.⁴

The politics are live. NNPC, the state oil company, has publicly argued that restricting imports would threaten supply security, and says Dangote has not shown "credible, independent or verifiable evidence" that it can meet total national demand.⁴ Marketer associations have warned a successful import ban would push prices up. A company whose domestic margin depends partly on how a regulator and a court rule is carrying a kind of risk that does not appear in its cash flow statement.

Concentration. This is one asset, in one country, in one commodity, with one controlling shareholder. There is no diversification inside it. A single prolonged outage, a policy change, or a crude supply disruption hits the whole business at once.

Currency. The shares are priced and will trade in naira. A foreign investor's return is the share price move and the naira move, and the naira has a long history of sharp depreciation. The company earns substantially in dollars, which helps the business — but your shares are still naira-denominated.

Margins are cyclical. See above. $24.50 a barrel is not a promise.

What it does and doesn't change

Dangote has genuinely moved the needle. It supplied close to 80% of Nigeria's daily petrol consumption in April 2026⁴ in a country that recently imported nearly all of it, while the three state refineries produced nothing at all.⁸ On the continental question the article opened with, it is one refinery against a gap that would take about 7.1 million barrels a day to close. It is roughly a tenth of the answer.

That is not a criticism. It is the scale of the problem. If the expansion to 1.4 million barrels a day lands on schedule in 2029, one privately owned plant in Lagos would cover close to a fifth of the continent's refining shortfall. Whether that happens on time and on budget is the open question — and the last ten years suggest megaprojects usually arrive late and cost more.
