Visa plans to acquire a "significant minority" stake in payments platform Interswitch, the Nigeria-based company said on Tuesday.
Interswitch did not provide financial details in its statement but a source confirmed media reports that Visa would buy a 20% stake for $200 million.
That would value Interswitch at $1 billion, giving it "unicorn" status — a term for tech companies with a valuation of a billion dollars or more.
Visa will join Helios Investment Partners, TA Associates, and IFC as the primary shareholders in Interswitch.
Andrew Toree, Visa's regional president for Europe, the Middle East, and Africa said that Africa — the world's second-fastest-growing banking market according to a 2017 McKinsey report — is a "priority region" for the company.
Interswitch has long been expected to launch an initial public offering (IPO) to allow the original investors to offload part of their stakes in the company.
Founded in 2002 by Nigerian entrepreneur Mitchell Elegbe, Interswitch also owns Verve — the largest domestic debit card scheme in Africa — and Quickteller, a consumer payments platform that enables money transfers, bill payments and mobile and internet air time purchases.
Quickteller processed over 42 million transactions monthly as of 31 July — the equivalent of more than 560 billion nairas ($1.82 billion).
The value of mobile money payments in sub-Saharan Africa grew by more than 15% from 2017 to 2018, according to industry group GSMA, to $26.8 billion.
The group, which represents mobile operators worldwide, also expects that regulatory reforms in Nigeria, Ethiopia, and Egypt could see more than 110 million new mobile money accounts added there in the next five years.
Rating agency Moody's in September assigned the company a B2 corporate family rating, noting that it processes some 90% of total electronic transactions in Nigeria — a market where electronic payments increased by 32% in 2018 and are expected to keep growing.
Moody's said Interswitch posted average net revenue growth of 17% from 2017-2019 and an average EBITDA margin of 40% over the same period.
It warned, however, that Interswitch's profitability could weaken due to interest costs for its bond issuance payments, and that the high concentration of its business in Nigeria was a risk factor.
