April 27, 2006 Market and Future Outlook YIT Oyj

Market outlook April 27, 2006 Financial research institutions estimate that the national economies of the Nordic countries will develop at a stable rate of 2.5-3.5 per cent in 2006-2008, outpacing growth in the EU by about one percentage point. Russia and Norway benefit from the high price of oil. The rate of growth in the economies of Russia, Estonia, Latvia and Lithuania is about twice as fast as in the Nordic countries. Moderate growth in euro interest rates supports calm development in investments and housing demand. The positive trend in incomes and the improving employment situation bolster the households’ consumption. Housing sales can be expected to be as brisk as in the previous year. Growth in exports and industrial output increases the need for industrial investments and maintenance in the Nordic countries. YIT Oyj
