Here are the major Jumia shareholders and their nationalities. MTN is the largest shareholder. Germany, Belgium, Luxembourg and France had representatives in the shareholders table. All numbers valid before Jumia listing on NYSE.

MTN Holdings (Mobile Telephone Networks Holdings) had the largest share at 29.7%. At Friday’s valuation of $3.9 billion in the NYSE, the “Others”, at 9.8%, will translate to about $380 million. I expect a big component of that to be employee-controlled. Largely, there are a couple of millionaires therein. They will need bodyguards in many Jumia offices (lol).

So, by nationality, Germans and South Africans are competing for largest shareholders position.
