The role of the Stichting Administratiekantoor whose primary role was to acquire and hold in trust ordinary Grontmij shares for which it issued convertible depository receipts ended on 28 June 2012. On that date, Grontmij’s depositary receipts were withdrawn and replaced by ordinary shares. As a result, the abolition of the administration of Grontmij shares became a fact.

The Stichting Administratiekantoor van aandelen Grontmij N.V. (‘Trust Office’) will continue to exist for another two years to enable holders of depositary receipts, who do not hold their depositary receipts via a financial intermediary, to exchange their depositary receipts for ordinary shares. Depositary receipts can be exchanged until 1 July 2014. The depositary receipts that were held via a financial intermediary were exchanged automatically on 28 June 2012.
