Contractor鈥檚 shares dive again as it confirms it is in 鈥榗onstructive and ongoing discussions鈥

Shares in Interserve slid more than 5% this morning after the contractor admitted it was in talks with its lenders, a month after it revealed it would have to increase provisions to cover loss-making energy-from-waste contracts.

In a statement to the Stock Exchange this morning, Interserve said it was 鈥渆ngaged in constructive and ongoing discussions with its lenders鈥.

Work was 鈥渦nderway to provide greater clarity on Interserve鈥檚 current trading and Energy from Waste provision, provided in the 14 September update announcement鈥.

A further announcement is expected 鈥渋n the coming days鈥, it added.

The group has not responded to suggestions it has hired business rescue specialists EY.

Last month in a trading update Interserve announced it was increasing the amount it was setting aside for its EfW deals from 拢90m to 拢160m. But the firm鈥檚 chief executive Debbie White (pictured), who joined the group at the beginning of September, admitted that this figure will not be enough.

Investors promptly dived out of the stock, sending Interserve鈥檚 shares down 53%.

The firm originally said in May 2016 that the cost of pulling the plug on the energy-from-waste sector would be 拢90m. It was then forced to revise this figure up to 拢160m, earlier this year.

In its statement last month, the firm said 鈥渢he anticipated timing and complexities of completion [of energy-from-waste contracts] mean that the board now considers it is likely that the final costs will significantly exceed the 拢160m currently provided鈥.
