Rolls-Royce Holdings heads into Tuesday’s session with investors on alert, following a Sky News report that the jet-engine manufacturer might unveil a new share buyback of up to 1.5 billion pounds as part of its annual results this week. The company wouldn’t comment on the report, and Reuters noted it was unable to confirm the information right away. Last July, Rolls-Royce bumped its upper range for underlying operating profit guidance to 3.2 billion pounds, and free cash flow hit 3.1 billion pounds—money remaining after covering operating costs and investments.
