Engineering giant Rolls-Royce is expected to report higher profits when it reveals its half-year earnings this week following a tough few years.
The engine maker is expected to report underlying pre-tax profit of £193m on Tuesday, up from £104m the previous year, while analysts expect an outflow of £461m due to the higher volumes of large engines sold at a loss and other one-off cash items.
Investors will be watching to see how the company progresses with its aim to deliver more than £1bn in free cash flow by 2020 to help fund a production drive.
Rolls-Royce is working to ramp up large engine output from 300 to 600 a year over the next few years following a series of profit warnings in 2014 and 2015.
In January, the firm also agreed to pay £671m to settle corruption probes with three global fraud squads.
The company's share price has shot up 40 per cent since the beginning of the year as investors expect an improvement to its cash flow over the next three years.
The interim results on Tuesday will be the first since new chief financial officer Stephen Daintith took over in April.
"The market will be looking closely at his comments and what scope for potential change in financial disclosure could emerge," said analysts at Deutsche Bank.
The company expects profit and free cash flow to be significantly weighted towards the second half of the year.
