Ultima has continued to grow its top line during its transition from "a professional services business with vendor capabilities" to a recurring revenue model, it noted in its strategic report for the year to 31 March 2022. Revenues rose four per cent to £107.8m in the period thanks to strong demand for hybrid cloud solutions, although net profits halved to £1.5m. The first UK partner to bag Platinum Plus status with Citrix, the Reading-based, Apse Capital-backed outfit also holds 14 Microsoft Gold badges.
