NTT is to buy South African IT firm Dimension Data for £2.1 billion ($3.2b) with the aim of offering “one-stop” ICT services to businesses worldwide.
The New York-listed Japanese carrier has offered an 18% premium in cash for the systems integrator.
NTT said the two companies had complementary geographic and product footprints, and believed the deal would help it boost revenue from value-added services for enterprises.
Dimension Data, which is listed on the London Stock Exchange, has 6,000 clients in 49 countries.
Dimension would continue to operate as a standalone entity, NTT said.
NTT CEO Satoshi Miura said: “By leveraging the complementary strengths of both companies, we are confident that we will provide end-to-end, global-one-stop and high quality ICT services. Dimension Data and NTT share the common vision to create new services and values to succeed in the coming age of cloud computing.”
