Impax Environmental Markets PLC

03 May 2011

Impax Environmental Markets plc announces that as at the close of business on 28 April 2011 its unaudited net asset value ("NAV") per ordinary share ("Share") was as follows:

NAV per Share (including current financial year revenue items)

139.62p

NAV per Share (excluding current financial year revenue items)

139.44p

Investments in the Company's portfolio have been valued on a bid price basis.

No adjustment for dilution to the above NAV has been made in respect of any Shares held in treasury as the Company's presently stated policy is that treasury shares will not be sold at less than NAV.

The Company's Shares have gone ex-dividend and the dividend of 0.75p per Share has therefore been deducted in the above NAV calculations.
