Driffield-based Cranswick Pet & Aquatics Ltd has been named as one of Britain’s fastest growing private-equity-backed firms in the Buyout Track 100, published by the Sunday Times and accountancy firm Deloitte. The Buyout Track 100 is published every year, and lists Britain’s private-equity-backed companies with the fastest growing profits (EBITDA) over the last two years. Cranswick Pet & Aquatics was formed in 2009, following a decision by Cranswick Pet Products and Tropical Marine Centre (TMC) to collaborate on a management buyout from Cranswick PLC. It achieved a place in the league table following annual profit growth of 35.4%, and was one of only 12 companies from Yorkshire and the North East to appear on the list.
