Trading Statement

Pre-Close Trading Update

WS Atkins plc ("Atkins" or the "Group"), the design and engineering consultancy group, today provides an update on trading in advance of its half-year results for the six months to 30 September 2012 which will be announced on 15 November 2012.

The Group's performance in the second quarter has been consistent with the outlook given at the time of its Interim Management Statement on 1 August 2012.

The good start to the year in our UK business has continued, with a modest increase in overall headcount in the year to date. Following the successful completion of the London 2012 Olympic and Paralympic Games we are commencing work on the legacy infrastructure.

Our consultancy business in North America continues to experience weak market conditions and we have taken further action in the first half of the year to reduce costs and right-size our resources in the region. We are making progress on the close out of legacy contracts in the Peter Brown construction management at risk business.

As noted previously, our first half performance in the Middle East will reflect project delays and lengthy contract variation negotiations, together with an increased working capital requirement across the region.

Asia Pacific and Europe is trading in line with expectations and Scandinavia in particular has performed well in the first half.

Our Energy business continues to trade well in buoyant markets across all sectors. In the UK nuclear market, our new partnership with Areva puts us in a strong position to target decommissioning, waste management and clean up opportunities.

Group headcount has increased during the year to date to around 17,700, up from 17,420 at the end of March, with notable growth in the Energy division.

Outlook

Overall, the outlook for the Group for the year remains unchanged and in line with our previous expectations at the time of the Interim Management Statement on 1 August.
