AUM update and new property investment business

London, 10 July 2014 - Impax Asset Management Group plc ("Impax" or the "Company"), the AIM quoted investment manager focused on environmental markets and related resource efficiency sectors, today provides a quarterly update of its assets under discretionary and advisory management ("AUM") and the acquisition of a property fund business.

The table below sets out the movements in the Company's AUM over the quarter ending 30 June 2014, when AUM reached £2,757 million. The Company continues to receive strong net inflows into its third party listed equity funds and accounts.

Yesterday, the Company has also agreed with Climate Change Capital Ltd ("CCC") the transfer to Impax of CCC's sustainable property fund business, comprising a highly regarded, two person investment team and the management contract for the Climate Change Property Fund, which is expected to complete its divestment activity and wind up during 2015. This transfer is consistent with the Company's on-going assessment of opportunities to establish further asset classes in order to broaden its offering to clients.
