Strong demand for "all areas of Apple" helped underpin an eight per cent calendar 2021 revenue jump at this Nottingham-based reseller, which separated from Westcoast Group to become a fully fledged independent company during the period. Net profits fell by £2m to £7.1m.

Helping Teeside University earn coveted Apple Distinguished School status, as well as wins encompassing Rubrik and HP solutions, are among the recent achievements trumpeted on XMA's website. The corporate, education and public sector-focused outfit hit the M&A trail last year, snapping up £8.6m-revenue Scottish IT services outfit Capito in May 2022.
