Rolls-Royce said on Wednesday it had appointed Bradley Singer, a partner from its largest shareholder ValueAct Capital, as a non-executive director on its board. The company said Singer, who will join the board with immediate effect, would become a member of its Science and Technology Committee, Reuters reported. Singer is a partner and chief operating officer of ValueAct Capital, the largest investor in Rolls-Royce with a shareholding of 10.8%. Rolls-Royce, under pressure after a series of profit warnings, has said in the past that ValueAct backed its plan to turn around the company. It is also up against a reemergent Bentley that recently pushed into the world of SUVs with their latest Bentayga mode,l which is aiming squarely at the new liking for high-chassis vehicles.
