Net profit: -5.5%
This IT services firm's 2017 UK accounts were overdue as we went to press, so we have had to fall back on old numbers for its year ending 31 December 2016, which showed a net loss of £3.6m on revenues that rose 26 per cent to £66m. Globally, Getronics is in growth mode, snapping up US MSP Pomeroy in July in a move that propelled its turnover beyond $1bn. It now has 9,000 staff and 2,800 active customers worldwide.
