Outlook

Outlook per Business Line Infrastructure – solid market Government programs in U.S. and Europe to stimulate the economy Long term investments, e.g. Central Europe, Dutch rail Climate change and New Orleans good for water market Strong growth in South America may soften Environment – healthy foundation from regulation and sustainability Environmental clean-up takes years, often based on regulation Focus on markets with demand: oil & gas, utilities Cost effective technology, vendor reduction, outsourcing > market share Interest in GRiP® growing, in U.S. and Europe Buildings – take opportunities through focus Focus RTKL on non commercial U.S. and international Project management U.K.: focus on infrastructure and Middle East Opportunities in schools, hospitals etc, also from stimulus money Demand for facility management increases

Outlook 2009 ARCADIS Building Global Leadership Backlog is healthy and grew slightly in 2008 Stimulus packages good for all three business lines Focus on cost savings, sales and preserving margins Acquisitions remain on the agenda Short term outlook is mixed, but… Sustainability, climate change, urban renewal, mobility and energy offer good long term perspective Given uncertain market no tangible outlook for 2009 ARCADIS Building Global Leadership
