From the outset, the banks’ view on Interserve was as follows: this may be a business in a debt crisis, but it is no Carillion. Where Carillion was run by fools taking outlandish risks with huge contracts, Interserve has strong management, makes a profit, and has predictable earnings and cashflow. Its problems stem from previous bosses’ dangerous moves into areas they didn’t understand, such as building waste-to-energy plants. But the company is nearly out of the other end of those operational problems.
