SSP was spun off from catering giant Compass in 2006 in a £1.3bn management buyout backed by EQT, the Swedish private equity firm. It also owns brands including Upper Crust, Camden Food and opened a pub called The Merchant at Liverpool Street station in March.
The group has been targeting the US and China with recent contract wins at Phoenix and JFK airports and at Hangzhou and Xian airports.
