Outlook for 2008 21

Outlook for 2008 • In January-September, – operating profit increased in Building Systems and Industrial Services, and – decreased in Construction Services Finland International Construction Services compared to 2007. • During the last quarter, – the operating profit of Building Systems and Industrial Services is estimated to be on the same level as in 2007, excluding the sales gain of EUR 14. 4 million from the divestment of the Network Services division. – The operating profit of Construction Services Finland International Construction Services is estimated to decrease clearly during the last quarter compared to the previous year. 22

Outlook for 2008 YIT estimates that revenue for 2008 will increase, but profit before taxes will decrease clearly compared to the previous year. The profit development in the last quarter faces uncertainty due to the development of consumer confidence and its effect on residential sales in Russia. 23
