YIT CORPORATION SUPPLEMENTS CAVERION CORPORATION’S REGISTRATION DOCUMENT AND THE SECURITIES NOTE AND SUMMARY RELATING TO YIT CORPORATION’S PARTIAL DEMERGER

YIT Corporation (”YIT”) has supplemented Caverion Corporation’s registration document and the securities note and summary relating to YIT’s partial demerger published on 4 June 2013 (together the “Prospectus”) with the information in a stock exchange release including a profit warning published by YIT on 25 June 2013, according to which YIT is reducing its guidance regarding operating profit for the year 2013. YIT now estimates that the revenue and operating profit based on segment reporting for 2013 will remain at the level of year 2012. In its guidance issued in connection with the financial statements bulletin for 2012 (February 5, 2013), YIT estimated that the Group revenue based on segment reporting will remain at the level of 2012 and the operating profit will grow in 2013.

The development of operating profit has in the Building Systems -operations, which will be transferred to Caverion Corporation in the partial demerger of YIT, been weaker than expected during the second quarter of the year due to lower than expected capacity utility rate particularly in service and maintenance. The guidance does not take into account non-recurring expenses related to the demerger.

Caverion repeats the estimate announced on 4 June 2013, according to which the Group’s revenue for the second half of 2013 is more than EUR 1.3 billion and EBITDA more than EUR 50 million. The guidance does not take into account the non-recurring expenses related to the demerger, nor the expenses related to any potential mergers or acquisitions.

The Finnish Financial Supervisory Authority has approved the supplement on 26 June 2013.

The supplement is available as of 27 June 2013 on YIT’s website at www.yit.fi/sijoittajat and Caverion’s website at www.caverion.fi/sijoittajat. The unofficial English translation of the supplement will be available as of 27 June 2013 on YIT’s website at www.yitgroup.com/investors and Caverion’s website at www.caverion.com/investors.

The registration document according to the Finnish Securities Markets Act, which includes information on Caverion and its business and financial position, as well as the securities note and summary (together with the registration document the “Prospectus”) related to the partial demerger disclosed by YIT on 5 February 2013 and the shares to be given as demerger consideration in connection with the partial demerger, have been available as of 5 June 2013 on YIT’s website at www.yit.fi/sijoittajat. The unofficial English translation of the Prospectus has been available as of 5 June 2013 on YIT’s website at www.yitgroup.com/investors.
