Atkins said it had traded “within expectations” during the first quarter of the year.
The trading update from Atkins said that the company has experienced no immediate impact from the European Union referendum, although the vote to leave the EU has created uncertainty in the market.
The company said it is trading in line within its expectations, and reports that it has won important projects in cyber security, defence, transportation and water.
In April the company combined its design, engineering, water, ground and environmental businesses to create an infrastructure division – a decision that is intended to simplify the business.
The update highlighted the company’s work on the Purple Line light rail project in Maryland in the US and the Riyadh Metro in Saudi Arabia.
Atkins said it also looked forward to a “positive outcome” from the government’s Hinkley Point review in autumn.
The company’s net borrowing in June stood at around £50M, with net funds in March at £191.7M.
