ARCADIS SECURES FINANCING FOR FUTURE GROWTH THROUGH U.S. PRIVATE PLACEMENT AND REFINANCING OF LOANS

June 30, 2011 – ARCADIS (EURONEXT: ARCAD), the international consultancy, design, engineering and management services company, announced today that it has completed a 10 year U.S. Private Placement (USPP) of \$110 million. In addition, the company has also refinanced most of its bank loans, taking on a \$245 million term loan facility with maturities in 2013 and 2016 and a new revolving credit facility of €150 million maturing in 2016. With these steps, ARCADIS is effectively creating financial room for the future growth of the firm.

The USPP is issued at 5.1% for the 10-year period with five U.S. investors purchasing ARCADIS notes. RBS and ING were jointly responsible for the transaction. The USPP funding will be used to replace existing bank debt. The remaining refinancing of bank debt was done with an expanded syndicate of six banks with Rabobank in a coordinating role. The syndicate now also includes a U.S.-based bank, allowing ARCADIS to optimize its cash management globally.

"With this step we diversify our sources of financing and extend the maturity profile of our debt," said Renier Vree, CFO for ARCADIS. "More importantly, however, is that this provides sufficient facilities to assist ARCADIS in achieving its growth plans over the next few years."
