The company made the prediction as part of a trading update ahead of its half-year results announcement on 12 August.
It added that it expects to "make progress" in 2009, and its cash position remains "strong" with average net cash in excess of ВЈ200m for the first six months of 2009.
The company said that it expected to reach financial close on the ВЈ147m Carlisle Northern Development route, which has been dogged by delays since Balfour was appointed last year.
