Interserve said it expects cost savings of at least £40mln to £50mln by 2020 from the plan, with 2018 savings estimated to be £15mln.
The firm said: “As a result of the 'Fit for Growth' initiatives, the Group's operating profit for 2018 is now expected to be ahead of current market expectations.”
It also added: “Overall 2017 trading performance before exceptional items is consistent with the trends outlined in the October market update and in-line with market expectations.”
The company, which is reviewing its contract portfolio and non-trading balance sheet items, also said that discussions with lenders over longer-term funding were progressing.
The group said it expects its net debt to peak in the first half of 2018, partly due to ongoing refinancing activity. It expects net debt at year-end 2017 to be about £513mln.
Providing a sound foundation
Debbie White, Interserve’s chief executive, said: "The new management team, and the Board, have been working to stabilise the business and provide a sound foundation to continue to serve our customers effectively, underpin our future growth and to restore shareholder value.
“This work has focused on managing the balance sheet, conducting a thorough assessment of the contract portfolio, and introducing new management disciplines, processes and cost controls under the 'Fit for Growth' programme."
