75 NSC Global

Revenue: £55.2m (-8%)

Net profit: 4.2% Staff: 218

Having supported the design and implementation of the biggest UK 5G network in 2019, this London Bridge-based Cisco Gold partner's UK subsidiary saw revenues fall back eight per cent to £55.2m in its year to 31 October 2020 (with its parent showing revenues down 19 per cent to £174.2m). Developing comms infrastructure for a small set of global clients in the TMT sector, NSC said in its annual accounts that it is looking to reduce concentration risk with largest client Atos in the coming years.

Covid impact

NSC said its 2020 revenue slide is a "direct result" of the pandemic. New clients bagged since year end mean it is confident of improving both revenues and margins in the years ahead, however.
