This Warwick-based player bills itself as "the UK's leading mission-critical network solutions provider", and recently won a £450m deal to provide telecoms services to Highways England. It has also become a sizeable player in the ICT channel through recent acquisitions and was recently crowned HPE UK and Ireland Solution Provider of the Year. As it hasn't filed any new accounts since last year, we've had to fall back on its annual accounts covering the year to 31 March 2017, which showed net profit falling from £32.2m to £21.6m on revenues that fell two per cent to £386.3m.
