🍞 The Biggest IPO in African History: Part 1 - The Cement Factory

Dangote began trading in the late 1970s on a loan from a wealthy uncle, moving commodities and reinvesting the profit. In the early 1980s, as oil revenues fell, the Shagari government introduced austerity measures and an import licensing system to conserve scarce foreign exchange, and licences became a barrier to entry for any potential importer.  Dangote's family already had government ties, so he secured the appropriate import licences quickly, a step that derailed many rivals. He built five terminals for importing and bagging bulk cement and became the dominant player in a market with unusual economics. Cement prices in Africa have long run around 200% higher than in any other region in the world. Dominating the import of an expensive, essential good throws off enormous cash.

Dangote benefitted from this uncharacteristically high price, and the margin he earned from being an importer became the capital he used to stop importing. Most traders would have defended the import franchise. He bet it against himself.

When the Federal Government privatised its loss-making cement companies around 2000, Dangote acquired a controlling stake, reported at about 66%, in the struggling Benue Cement Company. The company itself described the move as a strategic decision to shift from cement importation to local production. The logic was simple. Stop importing the finished good. Build the plant at home. Capture the margin that used to leak abroad. Then push the surplus out across the rest of the continent. It is import substitution as a business model and cement was the proof.

No account of how Dangote won is honest without the policy that made winning possible. In 2002 the Obasanjo administration adopted a Backward Integration Policy for cement. Nigeria sat on vast limestone reserves, so importing cement made little national sense. The policy allowed companies to keep importing only if they could show real investment in local manufacturing and owned land-based terminals, and it layered high tariffs and levies on imports. It set the country on the road to cement self-sufficiency, and the largest importer, Dangote, was best placed to lead the turnaround.

Supporters make a genuine case. One defender argued the policy was open to any Nigerian willing to take the risk of a huge industrial investment in a country notorious for policy reversals, and that Dangote simply took the plunge when others would not. Critics see a state-capital bargain. The favours, they argue, went beyond a general policy. Rivals felt the other side of the same policy. The importer Cletus Ibeto, among others, saw licences revoked amid tax disputes. Analysts of what they call state capture point to import bans on competing goods that squeezed rivals out of ports and markets.

However, two things can be true at once. Dangote took real risk and built real plants. He also operated inside a policy environment shaped in his favour. The two facts are not in tension; they are how the empire was actually built.

The first advantage is siting. Dangote's plants sit close to large limestone deposits and transport hubs, which lowers both production and logistics costs. The second is scale. Obajana, Ibese and Gboko together give the company by far the largest capacity in Nigeria, and scale lets it spread fixed costs and undercut smaller producers on unit cost. The third is integration. The group controls its own limestone, power generation, coal and trucking fleet, so it depends less on the bottlenecks that throttle competitors. The fourth advantage is distribution. Dangote is the most widely distributed cement brand in Nigeria, present across all 36 states, which means fewer supply gaps and more predictable delivery mid-project. That reliability lets it charge a premium. Retail surveys consistently show Dangote as the most expensive of the major brands, and structural engineers still specify it for serious work. Rivals such as BUA typically sell a few hundred naira cheaper per bag.

The result is pricing power. Analysts note that Dangote's recent growth has come from earning more per tonne sold rather than selling more tonnes, the signature of a company that sets the price rather than takes it. Its domestic market share has run around two-thirds, though it is slipping as competition sharpens. By revenue, Dangote held about 65% of the Nigerian market in the first half of 2025, down from roughly 73% a year earlier, as BUA and Lafarge, now operating as HBM Nigeria, took share.

The empire became public property on 26 October 2010. Obajana Cement Plc had been renamed Dangote Cement Plc by special resolution that July, with Benue Cement and other group entities merged into a single enlarged company. It then listed on the Nigerian Stock Exchange, placing its entire issued capital of about 15.5 billion shares on the market at 135 naira each.

The effect on the exchange was immediate and large. The listing added roughly ₦2.1 trillion, about $14 billion at the time, to the market's capitalisation, an increase of around 25% in a single stroke. The exchange's own administrator called it the biggest issue by a single company in the market's history. Dangote kept the free float deliberately thin, selling about $154 million of stock to reach a float of just 5.2%, and framed the exercise as creating an African champion capable of competing with the world's largest cement companies.

The reviews were not unanimous. Listing by introduction at 135 naira drew mixed verdicts on valuation at the time. Fifteen years on, Dangote Cement has been, at various points, the single most valuable company on the Nigerian Exchange, and it remains one of the largest.

Recently, the company made plans for a secondary listing on the London Stock Exchange. Expanding its investor base beyond the shores of Nigeria and positioning itself as a global player.

Read back over the cement story and a template emerges, step by step. Dominate the import of an essential good. Turn the rent into capital. Use policy protection and privatisation to move into manufacturing. Build the largest plant in the region, sited and integrated for the lowest cost. Capture the pricing power that scale and distribution create. Then list it, keep control, and carry the brand across Africa.

Every one of those steps has a direct echo in the refinery. Nigeria imported almost all its refined fuel; Dangote built the largest single-train refinery in the world to make it at home. The plant sits in a free zone engineered for cost. The state cleared subsidy and licensing obstacles in ways that helped make it viable. And now, exactly as in 2010, the asset is coming to the public market at a price that some call visionary and others call steep.

That is the question Part 2 takes up: what the refinery actually is as a business, and whether 525 naira a share is a fair price for the same playbook run at 10 times the scale.

If this is useful, don't gatekeep. Forward this to one person who needs it. That's how we grow 🍞
