Rolls-Royce recovery revs up, but CEO stays cautious

London

WARREN East's reboot of struggling industrial giant Rolls-Royce Holdings Plc gathered pace as the aircraft-engine maker's first-half profit more than doubled, aided by the chief executive's restructuring plan.

At the same time, Mr East left his 12-month outlook for "modest" performance improvements unchanged in guidance on Tuesday, warning that the London-based company faces production hurdles in the second half that will make or break its year and indicate whether the recovery has truly taken hold.
