The UK arm of this global SAP, Microsoft and Tibco partner recently drove off with a deal to revamp McLaren's critical IT enterprise solutions. As if in tribute to its new client, NTT Data UK zoomed through the £100m revenue barrier in its fiscal year to 31 March 2020 as growth ticked up to 25 per cent - thanks in part to its integration of RMA Consulting, a firm it acquired back in 2012. It blamed a £5.1m net loss for the year on investments made into the business.
