Africa's Business Revolution

Three McKinsey partners argue that the standard external picture of African business is wrong on the facts, and they supply a data set to prove it. They count roughly 400 companies on the continent with annual revenues above one billion dollars, document formal-sector growth across consumer goods, telecoms, banking, cement and agriculture, and map where the operating profit pools sit by country and sector.

The argument has three parts. First, aggregate continental statistics mislead because Africa is fifty-four distinct markets with different growth drivers, and firms that succeed pick specific cities and corridors rather than countries. Second, the winners are usually large, diversified, long-horizon groups such as Dangote, Safaricom, Equity Bank and the Mara and Aliko networks, because scale substitutes for missing infrastructure and institutions. Third, the constraint that matters most is not consumer demand but talent, distribution and power supply, so companies that build their own logistics and training capacity earn returns that pure asset-light entrants cannot.

The book rests on McKinsey Global Institute survey data, company financials and interviews with African chief executives. It is useful for investors sizing entry strategies and for operators planning expansion, because it is concrete about routes to market and about which sectors have already consolidated. The obvious caveat is authorship: consultants writing about a market they sell services into produce optimistic framing, and the growth projections made in 2018 did not survive the commodity cycle, the currency crises in Nigeria and Egypt, or the pandemic. Treat the structural observations as durable and the forecasts as dated.
