Future Outlook The strong order backlog and the integration of the new Building Systems business into the Group will significantly increase net sales in the last quarter. The result for the rest of the year will be weakened by the integration costs of Building Systems and the costs of downscaling measures in Sweden. Due to the integration costs and the costs of overhauling operations in Sweden, the result of the Building Systems business segment for the period from August 29 to December 31, 2003, is estimated to be in the red. Full-year pre-tax earnings is estimated to improve on last year’s figure. The Building Systems acquisition is expected to have a positive effect on earnings per share from 2004 onwards. YIT’s equity ratio declined due to the debt financing of the Building Systems acquisition. The aim is to return the equity ratio to its strategic target level of 40 per cent by 2006 at the latest. 30 October 2003 | YIT CORPORATION

Building Systems Acquisition and Integration YIT’s Interim Report January-September 2003 Building Systems Acquisition and Integration 30 October 2003 | YIT CORPORATION

Building Systems Acquisition YIT purchased from ABB, by an agreement signed on July 4, 2003, its Building Systems operations offering building systems, property and industrial services in Finland, Sweden, Norway, Denmark, the Baltic countries and Russia. The acquired business had net sales in 2002 of about EUR 1,130 million and approximately 9,100 employees. In terms of net sales, YIT became the largest Nordic company offering building system services whose network of business locations covers all of the Nordic countries. The acquisition was consummated on August 29, 2003, when the transaction price of EUR 169.2 million was paid and the business functions were transferred to YIT1. 1 The cash amount was determined in accordance with the deal agreement signed by YIT and ABB, such that the negative difference of the assets and liabilities of the balance sheet items being transferred in the asset purchase transactions was subtracted from the transaction value. The transaction price will be finalized by the end of the year, when the audited balance sheet calculations concerning the situation at the end of August have been completed. 30 October 2003 | YIT CORPORATION

Building Systems INTEGRATION The integration process will in the first phase be a 100-day intensive program. The process has been going forward according to plans. The goal is to have the functions mainly integrated by the end of 2003. In 2004 the economic- and IT systems will be integrated by full. The real work is done in country based integration teams. Integration teams in each country are responsible for the measures required due to the merger in their own responsibility areas (such as customers, marketing, suppliers, IT, finance, personnel administration, business premises and communications. One of the major subareas of the integration is the orientation and commitment of personnel. For example, in Finland a YIT days road show consisting of 21 personnel events around the country began in the second half of September. 30 October 2003 | YIT CORPORATION

Building Systems SYNERGY BENEFITS YIT estimates that the acquisition will yield annual synergy benefits of about EUR 10 million from 2004 onwards. Measures to identify and harness synergy benefits have been initiated on many areas such as purchasing local offices and administration IT and transfer of technology and busness models between former and current divisions telephone services cars and fuel travel services insurance. Synergies from business operations are aimed between different segments as well as through regional co-operation. Customer-oriented synergies are aimed between segments as well as inside the Building Systems division. 30 October 2003 | YIT CORPORATION

BUSINESS OPERATIONS IN SWEDEN Building Systems BUSINESS OPERATIONS IN SWEDEN At the beginning of October, an action programme was started up to pull the acquired Building Systems business into the black in Sweden as well from 2004 onwards. The main aspects of the action programme are the reduction of fixed costs and downscaling operations to match demand in loss-making areas. The reduction of fixed costs mainly pertains to white-collar employees, the rental costs of business premises and IT and administrative systems. The action programme will affect a total of about 400 people, of which about 250 are white-collar employees. This year, the costs of downscaling measures will be about EUR 10 million. They aim is to achieve cost-savings totalling about EUR 20 million per year and will come into full effect in 2005. 30 October 2003 | YIT CORPORATION
