Nippon Telegraph & Telephone Corp has attracted competing interest from MTN Group and Vodacom Group for the African operations the former Japanese monopoly acquired with the takeover of Dimension Data, according to people familiar with the matter.

Didata’s management is also considering buying back the African business and relisting its shares, the people said, asking not to be identified because the matter hasn’t been made public. The main prize is Didata’s Internet Solutions unit, the people said, as the companies seek to tap growing demand for Web-based services.

MTN is weighing an offer of as much as R8bn to get Internet Solutions, the people said. The structure of a deal hasn’t yet been decided as many options are still being discussed, including a potential partnership agreement, said the people. Tokyo-based NTT, the owner of Japan’s biggest mobile phone company, is open to approaches from interested buyers for the African business, other people said in June.

Africa’s largest wireless carriers are seeking to expand into Internet services to boost growth in their South African home market where demand for data is increasing much faster than their traditional voice business. The Johannesburg-based cross-town rivals also need to be able to compete with Telkom’s fast-growing BCX unit in gaining more business customers.

Didata “doesn’t respond to market rumour, speculation or hypothetical questions about the company or any of its affiliates or subsidiaries”, spokeswoman Hilary King said. Vodacom doesn’t comment on speculation, a spokesman said. A spokesman at MTN declined to comment.

NTT bought all of Didata’s stock for £2.1bn in 2010, which at the time was its second biggest purchase of an overseas asset. Didata, which has operations across the globe, provides live data for the Tour de France cycle race as well as IT services from outsourcing to supplying computer and networking equipment. — (c) 2017 Bloomberg LP
