The main UK subsidiary of this $9.4bn-revenue global reseller blamed Brexit-related uncertainty for a four per cent calendar 2021 revenue dip. Net profits widened from £6.5m to £7.6m, however, as services sales leapt by nearly a third to hit £30m (hardware and software sales both declined, to £346m and £182m, respectively).

Talking to CRN in November, outgoing EMEA president Emma de Sousa said the double-digit services growth exhibited by Insight's global business in its Q3 2022 results underlined its transtion to a "solutions integrator". She exited the NASDAQ-listed giant on 31 December 2022, with former Atos bigwig Adrian Gregory stepping in to fill her shoes.
