It’s here. On Monday, 7 September, Aliko Dangote and the transaction parties for the Dangote Refinery IPO signed the offer documents. The prospectus, which is the legal document governing the entire process, was also signed on that day.

This means the guessing is over. For most of this year, the headlines carried numbers that turned out to be inaccurate: a $50 billion valuation, a $5 billion raise, 10% of the company, etc. None of these figures were signed. Instead, the real terms are narrower in some places and more interesting in others.

So what exactly is the Dangote Refinery?  What does an IPO mean in practical terms? And now that the IPO is going live on the 14th of September, what should you know before deciding to take part? This guide walks you through all of it.

PS. The figures below are from the prospectus, the only document that legally describes this offer. This guide walks you through it, but doesn’t replace the need to read the prospectus yourself. Where I quote people like Dangote, David Bird (the refinery’s MD/CEO), the advisers, etc., those are remarks made at the signing ceremony that describe the company and its plans rather than the terms you’d be buying into.

First, what exactly is the Dangote Refinery?

A refinery is a facility that converts a raw material—such as crude oil, sugarcane, or mineral ore—into high-value, usable products through a series of complex industrial processes. For example, crude oil is refined into a diverse matrix of everyday energy products, including petrol, diesel, aviation jet fuel, kerosene, and cooking gas (LPG). Similarly, raw sugarcane is processed into refined sugar and molasses, while crude mineral ore is treated to extract essential metals like copper, aluminum, nickel, and gold.

The Dangote Petroleum Refinery and Petrochemicals FZE is a massive crude oil processing facility located in the Lekki Free Trade Zone in Lagos that converts crude oil to oil-related products, such as diesel, aviation fuel (also called jet fuel), and petrochemicals like polypropylene — a material used in everything from plastic packaging to car parts. 

It was commissioned in May 2023, after nearly a decade of construction and roughly $20 billion in investment. By February 2026, the refinery was reported to have reached its full processing capacity of 650,000 barrels (where 1 barrel = 159 litres) of crude oil per day. At the signing, both Dangote and the refinery’s MD/CEO David Bird attested to an improved capacity of 700,000 barrels a day. This makes it the world’s largest single-train refinery and the biggest refinery complex on the African continent. 

For context: a refinery “train” is the series of units that process crude oil into refined products. Most large refineries split that work across multiple trains running side by side. The Dangote Refinery processes 700,000 barrels a day through one which is why it holds the record. Now to put this into perspective, the next largest single-train refinery in the world, the SAMREF in Saudi Arabia, processes 400,000 barrels of crude daily. Dangote exceeds this by roughly 75%. 

The plant isn’t finished either. Under the group’s Vision 2030 plan shared at the signing ceremony, capacity should increase to 1.4 million barrels a day by 2029. Bird shared that the expansion is already funded, engineered and procured, and awaiting construction. If built on time, the Lekki complex will become the largest integrated refinery and petrochemical site in the world. This expansion is what the money sought after through the IPO is for— the proceeds will go toward growth capital expenditure.

The complex is also expanding sideways. The prospectus describes a Linear Alkyl Benzene plant with a production capacity of 400,000 tonnes a year — LAB is the key raw material in detergents, and reporting suggests it would roughly double Africa’s current output. This is becoming a full-scale industrial complex.

So, what is an IPO?

IPO stands for Initial Public Offering. When a company is “private,” ownership is held by a small group of people — the founders, early investors, or family members. The general public’s only interaction with those companies is through services it provides.  An IPO is when that company sells small pieces of ownership — shares — to the general public for the first time. It’s like finally opening the door and saying, “we’re letting new people in. You can own a piece of this.”

After an IPO, those shares are listed on a stock exchange — in Nigeria’s case, the Nigerian Exchange Group (NGX) — and anyone with a brokerage account can buy and sell them during market hours.

Why do companies do IPOs?

• To raise capital. Selling shares brings in money the company can use to expand, pay off debt, or invest in new projects. According to multiple reports, Dangote Refinery is raising up to ₦2.15 trillion, and the money is earmarked for the refinery’s expansion.
• To give early investors an exit. Founders and early backers who put money in years ago can now sell some of their stake and convert paper wealth into real money.
• To build credibility. A public listing signals maturity. It brings more scrutiny, yes, but it also builds trust with customers, partners, and lenders.

How does the IPO process work?

Here’s a simplified version of what happens behind the scenes:

1. The company appoints financial advisers. Investment banks and stockbrokers guide valuation, regulatory filings, marketing, and the sale and listing process. For this offer, Vetiva Advisory Services is the lead issuing house, with FirstCap and Stanbic IBTC Capital as co-leads and more than twenty other firms joining as issuing houses. Banwo & Ighodalo act for the issuer; Olaniwun Ajayi LP and ǼLEX are solicitors to the offer.
   
2. The company prepares a prospectus. This is the most important document in the process — a legal filing containing the company’s financials, its business model, how the money will be used, and every risk involved. It must be cleared and registered by the SEC before the offer can proceed. Dangote’s Prospectus was released on the 14th of September, and has over 190 pages.
   
3. The shares are priced. The company and its advisers determine how much each share will cost. This is based on the company’s valuation, market conditions, and how much demand there is from investors. Usually a price range is set first and the final number emerges from “book-building,” a process where institutional investors indicate how many shares they want and at what price they’d buy.
   
   The Dangote offer skips all this. It’s a fixed-price offer — ₦525 a share payable in full when you apply. Stanbic IBTC’s Oladele Sotubo said at the signing ceremony that advisers could have priced it against comparable listed stocks and gone higher, but Dangote’s instruction was to make it affordable for the average Nigerian.
   
4. The subscription window opens. For a set period — usually two to four weeks — members of the public can apply for shares at the stated price. Historically, in Nigeria this meant through a stockbroker or registrar. For this offer, however, you don’t need to visit a physical bank or stockbroker. The prospectus is explicit: retail investors “shall submit applications exclusively through a financial Intermediary, designated as an Electronic Application Channel.” There is no paper route for individual investors and you have to apply through one of the designated channels — bank apps, fintech platforms, stockbroker platforms, or the NGX Invest portal. The full list is on page 187. Piggyvest is one of them, sponsored by Chapel Hill Denham Securities Limited.
   
5. Shares are allotted and trading begins. If the IPO is popular, more people might apply for shares than are actually available (this is called “oversubscription”). When this happens, the company divides the shares up proportionally, meaning you might get a slightly smaller slice of the cake than you asked for, and the rest of your money gets refunded. Once everyone has their shares, the company officially debuts on the secondary market like the NGX, and everyday buying and selling begins.
   
   

An IPO is different from buying shares in a company that’s already listed. When a company like Dangote Cement or MTN Nigeria is already on the NGX, you can buy shares at any time during market hours at whatever price the market is trading at. Here, you’re buying from another investor who’s selling. 

With an IPO, you’re buying directly from the company at a fixed offer price, during a limited window, before trading even begins. It’s the difference between walking into a shop on opening day at the listed price and haggling in a market where the price moves every second.

Why does the Dangote Refinery matter to Nigeria?

For decades, Nigeria has produced crude oil and exported it to other countries for refinement. The four government-owned refineries in Port Harcourt, Warri, and Kaduna have been largely non-operational. The economics of this never made sense, and it cost the country billions of dollars in foreign exchange every year.

The Dangote Refinery is changing that equation. By refining crude locally and supplying a significant share of Nigeria’s petrol demand domestically, it’s reducing Nigeria’s dependence on imported petroleum products. It’s also generating foreign exchange through exports instead of draining it through imports and creates thousands of jobs — both directly at the facility and across the wider supply chain.

The prospectus gives us numbers to work with: revenue was ₦18.7 trillion in 2025 and ₦19.1 trillion in the first half of 2026 alone. That’s significant foreign currency flowing into the Nigerian economy, especially at a time when the naira has been under sustained pressure.

Ten years ago, a refinery in Lagos keeping planes in the air over Europe would have sounded like a stretch. But today, Dangote has been Europe’s largest supplier of jet fuel for consecutive months this year, overtaking the United States.

From a very significant angle, it does appear the Dangote Refinery is now deeply connected to how Nigeria’s economy will function going forward.

What’s being offered in the Dangote Refinery IPO?

For most of this year, reports had it that the Dangote Group would be selling around 10% of the refinery and raising something close to $5 billion. That is not what got signed. At the IPO signing ceremony on Monday, 7 September, the real terms came out: 4.1 billion ordinary shares at ₦525 each. If the offer is fully taken up, that will be ₦2.15 trillion, or roughly $1.6 billion.

The minimum subscription per shares is 10 shares at ₦5,250. After that, you buy in multiples of 10.

The company already has 120,128,915,901 ordinary shares in issue. Add the 4.1 billion new ones and you get 124.23 billion in total, which means this offer is about 3.3% of the enlarged company — not the 10% that was reported for most of the year.

Why is the offer smaller than expected? Partly because Dangote raised much of what it needed privately first — a $2.5 billion placement in July and a further $1 billion programme in August. And partly by choice. Dangote said at the signing that raising money wasn’t really the point, and that the size was deliberately capped.

Who can apply?

The prospectus splits investors into categories, and the category you fall into decides how you apply.

A Retail Investor is an individual — resident or non-resident Nigerian — who is not a Qualified Investor. That’s people like you and me.

Qualified Investors are the institutional and high-net-worth investors defined in the SEC Rules. They apply for a minimum of 50,000 shares through a separate route.

If you’re applying as a retail investor, two practical requirements. A valid BVN is mandatory for your application to be validated through an electronic channel. And you’ll need a CSCS account — your unique ID on the Nigerian Exchange, which is how your shares are tracked. Most application channels (like Piggyvest) will set one up for you during the process if you don’t have one.

What’s unusual about this offer?

There are a few things that stand out about the offer.

• You can be paid for holding. If you’re allotted at least the minimum subscription and hold it continuously for 12 months from the allotment date, you become eligible for one additional share at no cost. Hold for a further 12 months and you become eligible for a second. Two is the maximum. This programme is pending regulatory approval.
• The company reports in dollars, and intends to declare dividends in dollars. DPRP is a free zone entity and its reporting currency is USD. The prospectus says it “intends, subject to applicable laws and regulatory requirements, to declare dividends in USD” —but then the next line reads: dividends “may, however, be paid in USD, Naira or such other currency as the Issuer may determine.” So it rests in the realm of possibility, at least for now.
• It was screened for Sharia compliance before listing. Buraq Capital assessed the offer against AAOIFI Standard 21 and certified it compliant — the first pre-listing screening of its kind in the Nigerian capital market. The scholars went through the product mix and questions like pollution before signing off. In practice, it means faith-based investors who would normally sit out an oil listing can take part.
• The free-zone structure had to be built from scratch. The refinery is licensed by the Oil and Gas Export Free Zone Authority, and it doesn’t sit inside the Nigerian company law framework the way an ordinary listed company does. Making a free zone entity meet NGX and SEC disclosure requirements meant building the structure from scratch, which is part of why this took as long as it did.
• The retail target is enormous. FirstCap’s Ukandu Ukandu said the team is aiming at 10 million retail investors. The current Nigerian record for a single offer is somewhere between 130,000 – 180,000 which makes this widely ambitious, and explains the ₦525 price, the ₦5,250 minimum, and the decision to sell via retail providers.

Where will the shares be listed?

The primary listing will be on the Nigerian Exchange Group (NGX). This is where Nigerian retail investors like you and I will access the shares. On the main board of the NGX. An application has alreadt been made to list both the 4.1 billion new shares and the 120,128,915,901 existing ones.

Beyond Nigeria, the group has talked publicly about a pan-African listing — reports have mentioned Johannesburg, Egypt, Kenya, Ghana and Rwanda, and a possible secondary listing in London. None of that is confirmed, and none of it is in the prospectus. For a Nigerian retail investor, the NGX is the one that matters.

The physical build-out beyond Nigeria is further along than the listing talk. At the signing, Bird described starting in Namibia — tank farms on the coast, then a pipeline running inland to markets that are currently served badly or not at all. Dangote named Ethiopia, Kenya, Tanzania and Namibia among the group’s announced expansions. Again, none of this is part of the offer terms; it’s what management says it intends to do with the business.

Key dates to watch in the near future

These are the dates that were announced in the signing, and have now been signed into the transaction documents:

• Offer opens: 14 September 2026
• Offer closes:13 October 2026 — about a month, longer than the two-to-three-week window most Nigerian offers run
• Listing: main board of the NGX, after allotment
• CSCS accounts credited: no later than fifteen business days after the allotment date

If the IPO is oversubscribed, the issuer may absorb up to 30% above the offer size, subject to SEC approval. IPOs of this scale and complexity tend to face delays, so keep an eye on official announcements from the Dangote Group, the SEC, and the NGX for confirmed dates. We will also keep you posted.

The bigger picture

The Dangote Refinery IPO matters for reasons that go beyond any single portfolio. If it works, it could change how Nigeria’s capital market is seen at home and abroad. It could show that Nigerian infrastructure can attract serious money at global-scale valuations. It could deepen the NGX.

None of that makes it automatically a good deal for you personally. A compelling national story and a good personal investment aren’t always the same thing.

The useful thing now is that you don’t have to take anyone’s word for it, including ours. The prospectus exists; it’s cleared, and public. Read the risk factors on pages 134 to 155 — that section might seem boring but is really the most useful part of the document. Look at what the company owes and to whom. Look at the dividend policy and notice how much of it is conditional.

Then decide with what you actually know rather than what the timeline is telling you.

If you want to invest, the smartest thing to do right now is to prepare. Make sure your Piggyvest is active, KYC and BVN ready, and start setting funds aside. Pro tip: Save for the IPO using your Flex Naira wallet so you can earn some interest while you wait.

With investing, the opportunity isn’t necessarily tied to hearing the story early, but to understanding when to act.
