Market and Future Outlook 23 YIT CORPORATION

Northern Europe still booming in YIT´s territories • The boom peaked last year in the Nordic countries but continues outpacing that of euro zone. Growth in Russia and the Baltic countries is more than double compared to the Nordic countries • Positive earnings and employment trend strengthens household confidence • Growth in business premises outpaces that of housing production. Record-high population shift in Finland continues maintaining stable need for new housing production and increasing renovation works of old housing • Huge need for apartments in the large cities of Russia enables expansion of residential production over the long term • Growth in exports and industrial output increases the need for industrial investments and maintenance 24 YIT CORPORATION

Prices increased exceptionally in 2006 in Russia USD/m 2 Average price for residences in the major cities of Russia Moscow St. Petersburg Moscow Oblast Yekaterinburg N. Novgorod Rostov Samara Perm Local average wage indexes relative to residential prices in Moscow 2001: 940 USD/sq. m and St. Petersburg 2001: 469 USD/sq. m Source: Gosskomstat 25 YIT CORPORATION
