Interim Report Jan-Jun/2005 YIT changed over to IFRS (International Financial Reporting Standards) on January 1, 2005. Prior to the adoption of IFRS, YIT’s financial reporting was based on Finnish Accounting Standards (FAS). The Interim Reports for 2005 are drafted in accordance with IFRS recognition and measurement policies. The comparative figures for 2004 presented in the Interim Reports are also in line with IFRS. YIT Corporation’s IFRS comparative information for the 2004 financial year and a summary of the major changes were released as a stock exchange release on April 6, 2005. Due to revisions to IFRS standards, the comparative figures presented in the Interim Report differ in some respects from the figures presented in that stock exchange release. The IFRS-based financial information may have to be adjusted before it is included as information on the comparative period in the Group’s first IFRS financial statements, which will be drafted for the financial period ending on December 31, 2005. This is due to the revisions currently being made to IFRS norms. The financial figures presented for the Industrial and Network Services business segment have been prepared by combining the IFRS-based financial figures of Services for Industry and Data Network Services. The presentation is unaudited. Together we can do it. 3 August 5, 2005 | YIT CORPORATION

Network services • Broadband trend continues and the amount of transferred information increases.
