YIT ACQUIRES CAVERION, A CENTRAL EUROPEAN COMPANY OFFERING TECHNICAL BUILDING
SYSTEM SERVICES

YIT Corporation has agreed with the owners of Caverion GmbH that YIT will
acquire the entire business of Caverion. The price of Caverion's shares is EUR
73 million. The completion of the transaction is subject to approval by the
competition authorities. It is estimated that the acquisition will be completed
by August 31, 2010.

Caverion provides a wide range of services related to technical building systems
and their maintenance and operation. Its turnover in 2009 was EUR 440 million of
which 80 per cent was gained from Germany. Other countries where the company
operates are the Czech Republic, Hungary and Poland. The company has project
activities in other countries. Caverion has 1,900 employees.

The revenue of YIT's Building and Industrial services in 2009 was EUR 2,125
million, of which EUR 375 million was from Central Europe (Germany, Austria,
Poland, the Czech Republic, Hungary and Romania). YIT's personnel in Central
Europe is 2,060. Germany accounted for 53 per cent of YIT's revenue in Central
Europe in 2009.

YIT doubles its operations in Central Europe

The acquisition of Caverion is part of YIT's strategy to increase its building
system operations in Central Europe. It will strengthen YIT's local market
position in the Central European countries where YIT already has operations. YIT
will merge the companies in each country, which will improve YIT's ability to
serve its customers locally with a wide portfolio of services.

As a result of the acquisition, YIT will become the second largest provider of
building system services in Germany. The bigger size of German operations offers
opportunities to improve efficiency and profitability.

• Our aim is to develop our operations in Central Europe and become the market
  leader in Germany. The know-how of personnel transferring to YIT and our current
  personnel will complement each other in an excellent way. We target for
  profitable growth and increase the share of service and maintenance operations,
  says Arne Malonæs, President of YIT's Building and Industrial Services segment.

Outlook for 2010 unchanged

The acquisition will not change YIT Group's outlook for 2010. In its Interim
Report of April 29, 2010, YIT estimated that in 2010 the Group's revenue will
increase and profit before taxes will increase significantly compared to 2009.
