Interim dividend and scrip dividend alternative

17 May 2012

GCP Infrastructure Investments Limited is pleased to announce an interim dividend of 3.7 pence per ordinary share, for the period from 1 October 2011 to 31 March 2012. The interim dividend will be paid on 29 June 2012 to holders of ordinary shares recorded on the register as at the close of business on 25 May 2012.

The Company will also be offering a scrip dividend alternative under which shareholders may elect to receive new ordinary shares in lieu of the cash dividend. The price of a new ordinary share to be issued under the scrip dividend alternative will be calculated by taking the average of the Company's closing middle market quotations of an ordinary share for the five consecutive dealing days commencing on the ex-dividend date of 23 May 2012. A circular and form of election will be sent to shareholders on or around 31 May 2012. Shareholders who hold their shares in certificated form and who wish to automatically receive all or part of the interim dividend by way of new shares in the Company, not only on this occasion but on all future occasions where the Company decides to offer a scrip dividend alternative, should complete and return the form of election that will be provided to them with the circular by 5.00pm on 18 June 2012. For shareholders who hold their shares through CREST, a CREST Dividend Election Input Message should be submitted on each occasion where a scrip dividend alternative is offered.
