Arcadis has confirmed the takeovers of both engineering consultant Hyder and architect and design firm Callison.
The consultant upped its bid for Hyder after Japanese consultant Nippon Koei made a rival bid, with Arcadis’ offer valued at £296m on 5 September, an increase of 16 per cent on its initial offering.
After its failed offer, Nippon Koei said it would continue to seek out potential merger partners.
Hyder Consulting employs around 4,600 people with interests in the UK, Middle East, Germany, Asia and Australia.
Callison is a 1,000 person architectural and interior design consultancy with offices in the United States, China, Europe, Middle East and Mexico. It specializes in retail and office design and large mixed use projects.
Arcadis said the acquisitions would add around £396m (€500m) in gross revenue, increasing its overall revenue to around £2.4bn (€3bn) and employing more than 28,000 people worldwide.
The deals provide Arcadis with a new direct route into the Australian market, where the consultant will use Hyder’s assets to win work through multinational clients.
Neil McArthur, Arcadis CEO, said: “We are happy and proud to welcome the talented professionals of both Hyder and Callison to Arcadis. The complimentary and world-class capabilities that they bring will help us better serve our combined client base with global reach and help us deliver on our passion of improving the quality of life and being recognized as the best in our industry.”
