However, including acquisitions and, at constant currency rates, it is expected to be around four per cent.
Compass, which operates in 50 countries, said its operating margin is expected to have improved by around 40 basis points over the full-year.
The group said the ongoing challenging economic conditions are likely to continue to impact organic revenues in the near term but said it was encouraged by its pipeline of new business, while the strength of its balance sheet is enabling it to make acquisitions.
