Olive Catering Services has secured its 57th contract, at automotive services company MIRA, as it celebrates its third anniversary.
MIRA, based in Nuneaton, Warwickshire, provides car manufacturers with testing, certification and measurement services.
With an on-site team of five, Olive will now cater breakfast and lunch five days a week for 400 staff in a year-long contract valued at £170,000.
The contract was previously held by Compact Catering, part of Cygnet.
Olive co-founder Damon Brown said: "It is fantastic to have won this prestigious client almost three years to the day after we started the company."
It caps a successful start to 2007 for Olive that, with the MIRA contract, has seen it add £1.8m-worth of business during the period, with turnover for the full year forecast at more than £6.5m.
