This unified comms provider stepped up its M&A drive last month by acquiring Excell Group, its third and largest deal since taking on Macquarie Capital as its new private equity backer in May 2021. The acquisition hands Wavenet a "true London presence" and propells its revenue runrate beyond £100m. Counting Cisco, Mitel, Five9 and Silver Peak among its vendor pals, Wavenet saw revenue in its year to 30 April 2020 pogo by more than a quarter to £52.4m as it digested recent acquisition Solar. Organic growth hit 6.1 per cent and EBITDA £6.9m.
