SECURITY film company firm Pentagon is to float on the Alternative Investment Market (AIM) on April 1, with a value of £2.5 million.

The firm claims the flotation, which will raise £750,000, will allow it to buy processing equipment and increase staffing levels as part of a major expansion. Pentagon has recently won contracts to fit its SupaGlass laminate to the Range Rover Autobiography and the Citroen Xsara Enterprise van.

In a further development, the board of the group has been joined by Ron Bambra, former managing director of Kwik-Fit Fleet, who will take up a non-executive directorship. AIM is the London Stock Exchange's global market for smaller, growing companies.
