YIT HAS MADE AN INITIAL, NON-BINDING OFFER TO ACQUIRE HOCHTIEF SERVICE SOLUTIONS

YIT has made an initial, non-binding offer to acquire HOCHTIEF Service Solutions. On the basis of YIT’s initial offer, the seller has informed that YIT’s proposal qualifies the start-up of due diligence process and SPA negotiations.

YIT is not expected to be the sole bidder qualified to the next phase in the potential acquisition. As the tendering process and the sales negotiations are about to be initiated, the terms and conditions of the possible acquisition, including the purchase price, remain yet to be agreed. Due to this, YIT cannot at this stage estimate the possibility of the realization of the acquisition, the detailed timetable, its effects on the company's operations or the risks involved with the possible acquisition.

YIT expects to announce more information by the end of June. The business of HOCHTIEF Service Solutions relates to the Building Systems operations of YIT. Pursuant to the demerger plan signed on 21 February 2013 the business potentially to be acquired would be transferred to Caverion Corporation in the proposed partial demerger of YIT, subject to the approval of the demerger plan by the Extraordinary General Meeting of YIT Corporation on 17 June 2013. The prospectus relating to Caverion Corporation, an entity to be established in YIT’s partial demerger, will be published by estimated on June 5, 2013 and it will be available on YIT’s website (www.yitgroup.com).
