Why Nigeria’s billionaire founders keep majority of their equity despite listing

When Dangote Petroleum Refinery proposed listing on the Nigerian Exchange (NGX), the initial offering comprised roughly 3.3-3.4 percent of its total equity. This low dilution pattern aligns with a broader structural trend among Nigeria’s listed industrial powerhouses.

In most of Nigeria’s biggest listed companies, the billionaire founder or his holding company still controls well over 80 percent of the equity. What reaches the public market can therefore be a surprisingly small slice of an enormous business.

The result is a stock market in which millions of investors may technically be invited to become owners. Still, only a very small slice of the underlying company is actually available for them to own and trade.

Tesla founder Elon Musk owns about 20.3 percent of Tesla, according to the company’s latest regulatory disclosure. Jeff Bezos owns about 9.6 percent of Amazon based on Amazon’s 2025 proxy. Bill Gates’ last publicly documented Microsoft stake was about 1.34 percent, although Gates current holding is no longer regularly disclosed because he left Microsoft’s board.

The Nigerian Stock Exchange (NGX) maintains a baseline mandate requiring companies listed on its Main Board and Premium Board to maintain a minimum 20 percent free float held by public investors. However, an alternative regulatory provision creates the loop through which mega-cap listings bypass this percentage hurdle.

Under current NGX listing rules, a company can satisfy the free-float requirement if the absolute naira value of its publicly tradable shares meets or exceeds specific thresholds of N20 billion for the Main Board or N40 billion for the Premium Board, regardless of what percentage of the company that value represents.

For a mega corporation valued at N60 trillion, a 3.3-3.4 percent float represents roughly N2.15 trillion in public value. Because this naira figure far exceeds the N40 billion minimum threshold, the SEC and NGX approve the listing under existing rules.

Abdul Samad Rabiu owns 89.85 percent of BUA Foods directly, while the company’s 2025 annual report showed only 4.73 percent free float available to the market, according to information gleaned from the company’s website.

At Dangote Cement, Dangote Industries Limited owns 86.65 percent, and Dangote personally owns another 0.17 percent. That leaves roughly 13.2 percent outside the controlling shareholder and related interests.

While terms like founder ownership, controlling interest, free float, and beneficial ownership carry distinct legal meanings, the stark contrast in ownership structure across public exchanges remains unmistakable.

This is not uniquely Nigerian. Across Africa, companies such as MTN Group, Shoprite, Naspers and Safaricom also have significant strategic or founder/state shareholders. But South Africa generally has more dispersed ownership, while Nigeria’s Dangote Cement, BUA Foods and BUA Cement remain overwhelmingly controlled by their billionaire founders. The issue across the continent is therefore not listing alone, but how much equity is actually available to the investing public.

The OECD’s (Organization for Cooperation and Development) Africa Capital Markets Report 2025 found that African listed companies have unusually concentrated ownership: 40 percent of listed African companies have a large shareholder owning more than 50 percent of the equity, considerably higher than in emerging markets and globally. Also, African firms account for just 1 percent of global equity raised since 2000 and under 3 percent of worldwide listed companies.

Nigeria’s low-float model concentrates both ownership and investment risk. When a handful of billionaire shareholders overwhelmingly control the largest companies on the NGX, Nigerian investors have fewer genuinely diversified opportunities. At the same time, the exchange itself remains too shallow to achieve world-class liquidity and price discovery.
