After buying Kcom in 2019, private equity house Macquarie moved to offload its national ICT business to rival 44th-ranked Nasstar in June 2021. That business (which includes Avaya and Cisco partner Kcom Enterprise) saw revenues fall nine per cent to £166m in the year to 31 March 2020, partly due to the end of a multi-year contract with its largest customer. It also posted an EBITDA loss of £3.4m. Nasstar said the acquisition will make it "one of the largest independent providers of transformative technologies in the UK", with over 1,200 employees.
