Atkins has said results for the six months to 30 September will be in line with expectations on the back of strong growth in the Middle East.

Ed Wallis, chairman, also pointed to continued improvements in the group’s rail business and a recovery in its management consultancy arm.

The consensus forecast for the year to 31 March 2009 is £100m pre-tax profit on turnover of £1.37bn.

Wallis said: “Despite the uncertainty in the macroeconomic environment, our markets currently remain robust, driven by our clients’ requirements to invest in their infrastructure.

James Cooke, an analyst at Panmure Gordon, agreed. He said: “Our positive stance on Atkins is based on the strength and breadth of its operations both in the UK and internationally.”
