Engineering group Jarvis is a company with a chequered history, to put it mildly. It was involved in the Potters Bar rail crash, and it nearly went bust a couple of years ago.
Today came more bad news for any shareholders who had stuck with the company through thick and thin: a profit warning which wiped 70% off its stock market value.
Jarvis said changes in rail maintenance work and other rail agreements, along with a fall in its vehicle hiring business, would knock £8m off its full-year operating profits. Its shares slumped 54.25p to 23.75p. To put this in context, at their peak they were worth not 23p but £23 each.
