Final Adjustment of Acquisition of Isotek

Following completion of the acquisition of Isotek (Holdings) Limited ("Isotek") in November 2010 and agreement on the completion statements for Isotek with the resulting working capital adjustment announced on 2 August 2011, Filtronic announces a final adjustment since agreed with the vendors of Isotek.

As a result, in accordance with the terms of the acquisition, a total of 412,051 existing ordinary shares of Filtronic have been sold by Filtronic on behalf of the vendors of Isotek. As vendors of part of Isotek, Alan Needle and Chris Mobbs are therefore treated as having disposed of, respectively, 67,249 and 83,473 shares in Filtronic, in both cases at 24.5p per share.

As before, the net proceeds of the sale will be retained by Filtronic.
