Dangote Industries, owned by Africa’s richest man, has appointed MTN Group Ltd. CEO Ralph Mupita to the board of its fertilizer subsidiary as it gears up for expansion and a potential listing in Nigeria.

Dangote Fertiliser Ltd. Managing Director Vishwajit Sinha confirmed Mupita’s appointment in an email response to inquiries.

The high-profile addition comes as Dangote Fertiliser prepares for an initial public offering on the Nigerian Stock Exchange later this year.

Mupita previously led the listing of MTN’s Nigerian unit in 2019, a company whose revenue has more than quadrupled since.

With a market valuation of $8.6 billion, it is the exchange’s second-largest company after BUA Foods Ltd.

Mupita has led Africa’s largest wireless carrier for over five years, having joined MTN in 2017 as chief financial officer.

Prior to that, he held senior roles at South African financial services firm Old Mutual Ltd. and originally trained as an engineer.

Dangote has also indicated plans to list the group’s refinery business this year. The IPOs are aimed at raising capital and offering shares to institutional investors.
