WSP Agrees to Sell All of its Shares in Norwegian Company Multiconsult AS

MONTREAL, QUEBEC--(Marketwired - March 24, 2015) - WSP Global Inc. (TSX:WSP) ("WSP" or the "Corporation") today announced that, through its subsidiary WSP Europe AB, it has entered into an agreement with the Multiconsult Foundation (the "Foundation") pursuant to which WSP has agreed to sell all of its shares in Multiconsult AS ("Multiconsult"), representing 24.73% of the issued and outstanding shares of Multiconsult, to the Foundation (the "Shares"). The Foundation is currently a shareholder of Multiconsult and owns approximately 21% of the shares of Multiconsult. The transaction is subject to the completion of the proposed initial public offering of Multiconsult on the Oslo Stock Exchange (the "IPO") and to other customary closing conditions. If all conditions precedent are satisfied prior to June 30, 2015, the Shares will be transferred to the Foundation shortly prior to the closing of the IPO. The total gross proceeds to WSP would be approximately $85-95 million.

Pierre Shoiry, Chief Executive Officer WSP Global had the following comments in connection with the sale:

"WSP has been a long time shareholder of Multiconsult and we are selling our shares to the Foundation to provide the required float to ensure a successful IPO. It is not our strategy to hold minority positions in our operating companies and this scenario meets the objectives of both companies, while creating value for our shareholders. We wish Multiconsult continued success and hope for a successful IPO".

Closing of the transaction is subject to the satisfaction or waiver of all closing conditions and as such there is no assurance that the sale of the Shares will be completed.
