YIT'S INTERIM REPORT, JANUARY 1 - MARCH 31, 2007: REVENUE AND OPERATING PROFIT CONTINUE TO RISE


The YIT Group's revenue and operating profit continued to rise in Q1 2007.      
Revenue rose by 8 per cent and operating profit by 14 per cent compared with the
previous year. The Group's order backlog is at an all-time high.                

Building Systems forged ahead with improving profitability and focused on       
revenue growth. The business segment's operating profit as a share of revenue   
rose to 5.1 per cent (Jan-Mar/2006: 3.6%). Revenue was up 13 per cent. The order
backlog grew by 30 per cent to EUR 670.3 million (EUR 517.6 million).           

Profitability remained excellent in Construction Services. Operating profit was 
11.2 per cent (11.6%) of revenue. The order backlog was 65 per cent higher than 
last year, having risen to EUR 2,137.9 million (EUR 1,296.5 million).           

Industrial and Network Services' operating profit declined due to the weak      
market for network services and the final completion of the downscaling measures
carried out in 2006. EUR 1.0 million in downscaling expenses were booked in     
operating profit during the period. The operating profit margin was 4.5 per cent
(4.9%). The order backlog grew by 4 per cent to EUR 228.8 million (EUR 219.5    
million).                                                                       

“On the whole, construction and demand for building system services have        
remained solid in our whole business territory. Demand for new housing has      
stayed good in Finland. The number of residences YIT sold in Russia decreased   
compared to the previous year, but the value of sales stayed the same. Trends
in Industrial and Network Services were favourable in industrial projects and 
maintenance. The market for network services has remained challenging,” says    
Group CEO Hannu Leinonen.                                                       

“All in all, the outlook for 2007 is still favourable. Strong need for housing  
in the large cities of Russia enables us to expand our residential production   
over the long term, too. Thanks to our exceptionally robust order backlog and   
the good market situation, we are well-poised to forge ahead with profitable    
growth in line with our plans,” adds Leinonen.                                  

Revenue growth 8 per cent                                                       

The YIT Group's revenue for the January-March period grew by 8 per cent on the  
previous year without major acquisitions and amounted to EUR 833.5 million      
(Jan-Mar/2006: EUR 768.8 million). Revenue in Russia remained on last year's    
level during the first months of the year and amounted to EUR 48.1 million (EUR 
50.3 million). Of the revenue, 55 per cent came from Finland (57%), 33 per cent 
from the other Nordic countries (31%), 6 per cent from Russia (7%) and 6 per    
cent from the Baltic countries (5%).                                            

The share of revenue generated by the maintenance and servicing business was 36 
per cent (35%), or EUR 299.7 million (EUR 269.8 million).                       

YIT also keeps track of trends in the shares of revenue generated by consumer   
services, long-term service agreements, project development and contracting. In 
the January-March period, consumer services accounted for 26 per cent of        
revenue, long-term service agreements for 28 per cent, project development for 9
per cent and contracting for 37 per cent. YIT's strategic objective is to       
increase the relative share of revenue accounted for by consumer services,      
long-term service agreements and project development.                           

Operating profit growth 14 per cent                                             

Operating profit grew by 14 per cent on the previous year and amounted to EUR   
61.2 million (EUR 53.7 million). The operating profit margin was 7.3 per cent   
(7.0%). Profit before taxes rose by 9 per cent to EUR 54.8 million (EUR 50.1    
million). Earnings per share were up 7 per cent to EUR 0.31 (EUR 0.29). Equity  
per share was EUR 4.95 (EUR 4.23). Return on investment for the 12-month period 
ending at the conclusion of the review period was 25.4 per cent (28.1%).        

Financial position remains stable                                               

Invested capital in Russia increased due to growth in business operations, the  
acquisition of plots and ongoing volume growth in production. At period's end,  
26 per cent, or EUR 314 million, of the Group's invested capital was tied up in 
Russia. At the end of 2006, these figures were 23 per cent and EUR 279 million. 
The Group's financial position remained stable. Net debt was EUR 540.9 million  
(EUR 334.2 million). The gearing ratio rose to 85.6 per cent (62.7%). The equity
ratio was 31.8 per cent (33.5%). The balance sheet total at the end of the      
report period was EUR 2,155.9 million (EUR 1,722.0 million).                    

Order backlog growth 49 per cent                                                

The Group's uninvoiced backlog of orders rose to a record high. It was 49 per   
cent higher at the end of the period than a year earlier, having risen to EUR   
2,995.4 million (EUR 2,007.2 million). At the end of 2006, the order backlog was
EUR 2,802.3 million. The margin of the backlog is good. Due to their nature,    
part of the Group's maintenance and servicing operations are not included in the
order backlog.                                                                  

Number of employees 22,400                                                      

YIT's number of employees has risen since the previous year. In the review      
period, the Group employed 22,444 (21,131) people on average. At the end of the 
period, the Group had 22,418 employees (21,140). Of YIT's employees, 51 per cent
work in Finland, 36 per cent in the other Nordic countries, 7 per cent in the   
Baltic countries and 6 per cent in Russia.                                      

Northern Europe still booming                                                   

The boom in the Nordic countries peaked last year, but will continue during the 
upcoming years, with growth outpacing the euro zone by about one percentage     
point. Russia and Norway still benefit from the high prices of oil. The rate of 
growth in the Estonian, Latvian and Lithuanian economies is almost three times  
as fast as in the Nordic countries, while it is double in Russia. Especially in 
Russia and Latvia, fast growth has also resulted in rapid inflation.            

Euro interest rates are seeing moderate growth.The positive earnings trend and  
the improvement in the employment count bolster household confidence in all of  
YIT's business countries. The record-high population shift in Finland is        
continuing, maintaining stable need for the construction of new housing and     
increasing renovation works on old housing. Growth in the construction of       
business premises outpaces housing production. Strong demand for housing in the 
large cities of Russia enables the company to expand residential production over
the long term, too. Growth in exports and industrial output increases the need  
for industrial investments and maintenance in all the Nordic countries.         

YIT estimates that it will start up more residences than last year              

YIT estimates that this year it will start up the construction of about 2,700   
market-financed residential units in Finland (start-ups in 2006: 2,818), about  
4,500 in Russia (3,699) and about 900 in the Baltic countries (887).            

Outlook for 2007                                                                

We estimate that revenue and operating profit (EBIT) in 2007 will increase      
compared to the previous year.                                                  

The outlook for revenue growth is supported by the record-high order backlog,   
the continuing boom and YIT's major investments in the Russian market. The      
healthy margin of the order backlog and the company's own profitability         
improvement measures underlie our expectations of growth in operating profit.

YIT's service chain spans the entire life cycle of investments. The life cycle  
strategy seeks to achieve better service capability, growth in our business     
operations and a steadier stream of profits. Part of the Group's revenue comes  
from its industrial, property, telecom network and traditional infrastructure   
maintenance and servicing business. In the review period, the revenue generated 
by this business was EUR 299.7 million (EUR 269.8 million), representing 36 per 
cent (35%) of total revenue.                                                    

YIT also keeps track of trends in the shares of revenue generated by consumer   
services, long-term service agreements, project development and contracting. In 
the January-March period, consumer services accounted for 26 per cent of        
revenue, long-term service agreements for 28 per cent, project development for 9
per cent and contracting for 37 per cent. YIT's strategic objective is to       
increase the relative share of revenue accounted for by consumer services,      
long-term service agreements and project development.                           

Of the revenue, 55 per cent came from Finland (57%), 33 per cent from the other 
Nordic countries (31%), 6 per cent from Russia (7%) and 6 per cent from the     
Baltic countries (5%).                                                          

The YIT Group's strategic target for revenue growth is 10 per cent annually on  
average. In addition, YIT has set itself the goal of increasing its revenue in  
Russia by an average of 50 per cent annually during the 2006-2009 period.       

OPERATING PROFIT GROWTH 14 PER CENT                                             

Operating profit grew by 14 per cent on the previous year and amounted to EUR   
61.2 million (EUR 53.7 million). The operating profit margin was 7.3 per cent   
(7.0%).

*) The operating profit of the Industrial and Network Services business segment 
in January-March 2007 includes the final costs of the downsizing of Network     
Services carried out in 2006, EUR 1.0 million. Previously, YIT estimated that   
the additional costs that would be booked in early 2007 would amount to no more 
than about EUR 3 million.                                                       

Profit before taxes rose by 9 per cent to EUR 54.8 million (EUR 50.1 million).  
Profit after taxes was EUR 40.1 million (EUR 37.7 million). Earnings per share  
were up 7 per cent to EUR 0.31 (EUR 0.29). Equity per share was EUR 4.95 (EUR   
4.23). Return on investment for the 12-month period ending at the conclusion of 
the review period was 25.4 per cent (28.1%).                                    

YIT has set itself the target of increasing its operating profit to 9 per cent  
of revenue in the 2007-2009 strategic period. The strategic target level for    
return on investment is 22 per cent.                                            

ORDER BACKLOG GROWTH 49 PER CENT                                                

The Group's uninvoiced backlog of orders rose to a record high. It was 49 per   
cent higher at the end of the period than a year earlier, having risen to EUR   
2,995.4 million (EUR 2,007.2 million). At the end of 2006, the order backlog was
EUR 2,802.3 million. The margin of the backlog is good. Due to their nature,    
part of the Group's maintenance and servicing operations are not included in the
order backlog.

THE GROUP'S FINANCIAL POSITION REMAINS STABLE                                   

Invested capital in Russia increased due to growth in business operations, the  
acquisition of plots and ongoing volume growth in production. At period's end,  
26 per cent, or EUR 314 million, of the Group's invested capital was tied up in 
Russia. At the end of 2006, these figures were 23 per cent and EUR 279 million. 
The Group's financial position remained stable. Interest-bearing liabilities at 
the end of the period amounted to EUR 580.3 million (EUR 366.8 million) and     
liquid assets to EUR 39.4 million (32.6 million). Net debt was EUR 540.9 million
(EUR 334.2 million). The gearing ratio rose to 85.6 per cent (62.7%). The equity
ratio was 31.8 per cent (33.5%).                                                

The target level for the equity ratio is 35 per cent. The strategic dividend    
payout target is 40-60 per cent of annual earnings after taxes and minority     
interest.                                                                       

Short-term credit was converted into long-term credit by means of two EUR 50

liabilities in the balance sheet and the remainder comprises off-balance sheet  
items as per IAS 39. The interest on sold receivables paid to financing         
companies, EUR 2.7 million (EUR 2.2 million), is included in financial expenses 
in its entirety.                                                                

Participations in the housing corporation loans of unsold completed residences, 
EUR 30.6 million (EUR 15.6 million), are also included in interest-bearing      
liabilities, but the interest on them, EUR 0.4 million (EUR 0.2 million), is    
booked in project expenses, as said interest is included in housing corporation 
maintenance charges.                                                            

Interest-bearing liabilities included EUR 2.8 million in leasing commitments

The balance sheet total at the end of the report period was EUR 2,155.9 million 
(EUR 1,722.0 million).

MAJOR NEAR-TERM BUSINESS RISKS AND UNCERTAINTIES                                

YIT's risk management policy aims to identify the major risk factors, taking the
special characteristics of YIT's business operations and environment into       
consideration, and optimally manage the overall risk level so that the company  
achieves its strategic and financial objectives. YIT's risk management is an    
integral part of the Group's management, monitoring and reporting systems.      

YIT has specified the Group's major risks as well as means of managing strategic
and administrative risks. YIT's major strategic risk factors are related to     
growing both organically and through acquisitions, capital management, managing 
tender-based contracts, ensuring the availability and competence of employees   
and general economic development. In the case of administrative risks, YIT      
focuses on the further development of its successful corporate culture and      
management system.                                                              

The financial risks related to the YIT Group's business are liquidity, interest 
rate, foreign exchange and credit risks. An account of the financial risks is   
presented in the notes to the 2006 financial statements and in the notes to the
January-March/2007 Interim Report. 

The key objective of the management of accident risks is to minimize YIT's      
losses from identified risks and thereby safeguard the company's financial      
result and continuity of operations.                                            

A more detailed account of YIT's risk management policy, the major risks and    
their management has been published in the 2006 financial statements and Annual 
Report. Information is also available from www.yitgroup.com. The risks have not 
changed significantly after the financial statement date.

RESOLUTIONS PASSED AT THE ANNUAL GENERAL MEETING                                

YIT Corporation's Annual General Meeting was held on March 16, 2007. The Annual 
General Meeting adopted the 2006 financial statements and discharged the members
of the Board of Directors and the President and CEO from liability. The Annual  
General Meeting confirmed that a dividend of EUR 0.65 would be paid per share   
(EUR 0.55 for 2005, taking into account the halving of the nominal value of the 
share on March 24, 2006), to a total of EUR 82.4 million (EUR 68.6 million).    
March 21, 2007, was set as the dividend record date, and March 28, 2007, as the 
dividend payout date.                                                           

The Annual General Meeting decided to elect a chairman, vice chairman and three 
ordinary members to the company's Board of Directors. The meeting resolved to   
keep the composition of the Board unchanged: Chairman Reino Hanhinen, Vice      
Chairman Eino Halonen and members Sari Baldauf, Antti Herlin and Teuvo Salminen.
At its organization meeting on March 16, 2007, the Board elected from amongst   
its number Eino Halonen as the chairman and Teuvo Salminen and Reino Hanhinen as
the members of the Audit Committee.                                             

The Annual General Meeting re-elected PricewaterhouseCoopers Oy, Authorized     
Public Accountants, as the company's auditor to audit the administration and    
accounts during the present financial period. PricewaterhouseCoopers Oy         
appointed Göran Lindell, M.Sc. (Econ.), Authorized Public Accountant, as chief  
auditor.                                                                        

The Annual General Meeting decided on amendments to the Articles of Association.
The amendments to the Articles of Association were entered in the Trade Register
on March 30, 2007.                                                              

A decision was made to amend Article 3 of the Articles of Association such that 
references to the nominal value of shares and the minimum and maximum share     
capital were deleted and replaced with a statement that the shares of the       
company belong to the book-entry securities system.                             

A decision was made to add two explanatory statements to Article 4 of the       
Articles of Association to the effect that when the chairman is prevented from  
discharging his duties, said duties will be discharged by the vice chairman.    

Article 6 of the Articles of Association includes a regulation on the signing of
the company's business name and powers of procuration. The new Companies Act    
includes a provision on representing the company. The new Act does not recognize
the concept of signing the business name. A decision was made to account for the
provisions of the new Act in the wording of the proposal. No changes to the     
content were made.                                                              

A decision was made to add the word “otherwise” to Article 8 of the Articles of 
Association, which sets forth rules for matters such as the manner in which     
meetings are to be convened.                                                    

A decision was made to amend Article 9 of the Articles of Association such that 
the list of matters to be dealt with at the Annual General Meeting accounts for 
the new Companies Act's provisions on meeting agendas.                          

A decision was made to amend Article 10 of the Articles of Association such that
its stipulations concerning the inclusion of the shares in the book-entry       
securities system were deleted and replaced with a provision stating that       
disputes on the application of the Companies Act shall be resolved by way of    
arbitration.                                                                    

A decision was made to delete Article 11 of the Articles of Association, which  
set forth regulations on the obligation to redeem the company's shares once a   
certain shareholding limit is exceeded.                                         

Since the Articles of Association were amended in the manner specified above, a 
decision was made to account for the discontinuation of the nominal value of the
company's shares in the terms and conditions of share subscriptions under the   
share option programmes, and that the full subscription price shall be entered  
into the share capital when shares are subscribed for with the share options;   
therefore, a decision was made to delete the provision in the terms that sets   
the maximum amount by which the share capital can be increased.                 

A decision was made to increase the share capital by EUR 82,822,459.92 to EUR   
146,210,995.92 by means of a reserve fund transfer, whereby the funds in the    
share premium reserve, EUR 82,822,459.92, were transferred into the share       
capital. New shares were not issued when the share capital was increased. The   
increase was entered in the Trade Register on March 30, 2007.                   

SHARES AND SHARE CAPITAL                                                        

The company has one series of shares. Each share carries one vote at general    
meetings and confers an equal right to a dividend.                              
                                                                                
YIT Corporation's share capital was EUR 63,388,536.00 at the beginning of the   
review period and the number of shares outstanding was 126,777,072. Due to the  
decision by the Annual General Meeting to increase the share capital, the share 
capital amounted to EUR 146,210,995.92 at period's end.                         
The number of shares was unchanged and was 126,777,072 at the end of the period.

During the review period, no share issues were organized and convertible bonds  
or bonds with warrants were not floated. At the end of the period, the Board of 
Directors did not have valid share issue authorizations or authorizations to    
issue convertible bonds or bonds with warrants.

25.80 (EUR 22.38).                                                              

The value of share turnover during the review period amounted to EUR 1,597.9    
million (EUR 868.8 million) and the number of shares traded to 67,591,489       
(42,236,012). Market capitalization at the end of the period was EUR 3,270.8    
million (EUR 2,792.9 million).                                                  

Own shares                                                                      

At the beginning of 2007, YIT Corporation held 400 of its own shares,           
representing 0.0 per cent of the company's shares. YIT Corporation's Board of   
Directors decided to annul the YIT shares in the company's possession           
immediately once the amendment to the Articles of Association had been entered  
in the Trade Register. The annulment of the shares was entered in the Trade     
Register on April 10, 2007. YIT acquired its own shares in December 2005.  
     
At the end of the review period the Board of Directors did not have             
authorizations to purchase or dispose of YIT's own shares. YIT's subsidiaries   
did not own shares in the parent company during the period.  

International ownership rises to 50 per cent

period and 13,635 (9,928) at its end.                                           

A total of 45.9 per cent of YIT's total shares outstanding (39.9%) were owned by
nominee-registered or non-Finnish investors at the beginning of the year and    
50.3 per cent (46.1%) at the end of the period.                                 

NORTHERN EUROPE STILL BOOMING                                                   

Growth in the global economy got off to a more favourable start early in the    
year than expected. Growth slackened in the United States, but this was offset  
by the rebounding of Europe and Japan, while China and India, the new industrial
countries of Asia, are still seeing extremely fast growth with low inflation.   
The boom in the Nordic countries peaked last year, but will continue during the 
upcoming years, with growth outpacing the euro zone by about one percentage     
point. Russia and Norway still benefit from the high prices of oil. The rate of 
growth in the Estonian, Latvian and Lithuanian economies is almost three times  
as fast as in the Nordic countries, while it is double in Russia. Especially in 
Russia and Latvia, fast growth has also resulted in rapid inflation. Inflation  
is the key reason why the EMU entry of the Baltic countries will most likely be 
pushed back to after 2010.                                                      

Euro interest rates are seeing moderate growth. The positive earnings trend and 
the improvement in the employment count bolster household confidence in all of  
YIT's business countries. The record-high population shift in Finland is        
continuing, maintaining stable need for the construction of new housing and     
increasing renovation works on old housing. Growth in the construction of       
business premises outpaces housing production. Strong need for housing in the   
large cities of Russia enables the company to expand residential production over
the long term, too. Growth in exports and industrial output increases the need  
for industrial investments and maintenance in all the Nordic countries.         

Finland                                                                         

In March, the Research Institute of the Finnish Economy ETLA estimated that     
Finland's GDP will rise by 2.7 per cent this year. In the 2006-2011 period, the 
average rate of growth would be 2.8 per cent. The improvement in the employment 
count, the good trend in incomes and the still moderate interest rate level     
support household consumption and demand for housing. Growth in the disposable  
incomes of households will rise to 3.7 per cent this year and to 4.3 per cent   
the next. This change will be reflected in household consumption. Investments in
machinery and equipment - exclusive of energy investments - will grow by 2.3 per
cent this year and 3 per cent the next. Installation of nuclear power plant     
equipment will increase the rate of investments in the sector to 13.2 per cent. 

The business cycle report published by the Confederation of Finnish Construction
Industries RT in April states that the volume of construction will grow by 3.5  
per cent this year and 3 per cent the next. Residential construction will stay  
at a good level. Repair works will remain brisk. According to RT, 33,000        
residential units will be started up this year, while the number of start-ups   
was 33,400 last year. In March, the Ministry of Finance estimated that          
residential start-ups will number 32,000-33,000 units and forecast total growth 
of 4-5 per cent in building construction for this year. Office construction will
be on the up, especially in the Greater Helsinki Area. Construction of          
commercial premises will also remain brisk. Annual growth in renovation works   
will be 2-3.5 per cent during the present decade. Growth in new construction and
renovation maintains demand in the construction and building system markets     
(heating, plumbing, air-conditioning, electrical and automation contracting, and
maintenance). The market for industrial, property and infrastructure maintenance
will expand as the outsourcing trend progresses. Growth in the number of        
broadband connections has slackened and investments to expand the fixed and     
mobile phone networks will remain slight.                                       
                                                                                
Sweden                                                                          
                                                                                
In March, the Swedish National Institute of Economic Research KI estimated that 
Sweden's GDP will grow by 3.9 per cent this year and 3.4 per cent in 2008. The  
factors underlying this positive trend are the high capacity utilization ratio  
in industry, solid earnings, the positive incomes trend enjoyed by households   
and the low interest rates. The unemployment rate will decline to 4.3 per cent. 
Inflation will accelerate to 2.1 per cent this year and 2.4 per cent the next.  
The Riksbank, Sweden's central bank, has indicated that it will raise its policy
rate to 3.5 per cent in the summer. KI expects that the policy rate will        
continue to rise to 4.75 per cent in 2009. The growth of the national economy is
on a broad footing. In 2007, exports will increase by 7.1 per cent due to       
international demand and the effect of the relatively weak Swedish kronor. Fixed
investments will increase by 9.1 per cent this year, but growth will slacken to 
4.7 per cent the next. Fixed investments by industry will increase by 7 per cent
during the present year, and next year by 2.9 per cent. Investments by the      
service sector are higher and growing faster than those of industry, rising by  
7.1 per cent this year and 6.6 per cent the next.                               

According to the business cycle barometer KI released in March, the order       
backlogs of construction companies have increased, employment has improved, and 
companies expect to see further production growth. Two-thirds of construction   
companies reported that the shortage of skilled labour slows down growth, and 40
per cent expect tender prices to rise. At the beginning of April, the Swedish   
Construction Federation BI predicted that residential investments will grow by  
10 per cent this year and by 2 per cent the next. Production of other types of  
buildings will see growth of 9 per cent this year and 5 per cent in 2008.       
Construction represented 8 per cent of GDP and accounted for 20 per cent of GDP 
growth. The labour shortage has been met with foreign labour and strong         
productivity development.                                                       

Norway                                                                          
                                                                                
Norway's boom continues. According to the forecast released by Statistics Norway
in February, GDP will grow by 3.3 per cent this year and by 2.6 per cent the    
next. Household consumption will grow by 3.8 per cent this year and by 3.5 per  
cent the next. The vigorous growth in fixed investments that got under way in   
2004 will slacken to 5.8 per cent on the heels of the slowdown in the growth of 
housing investments to 4.4 per cent this year due to capacity problems, and     
correspondingly to 0.3, 0.9 and 3.5 per cent in 2008-2010. The construction of  
33,300 residential units was started up last year. However, residential         
production will remain brisk, as the construction of 6,079 residential units got
under way in January-February this year, 21.4 per cent more than in the same    
period last year. The floor area of business and industry buildings started up  
in that period was 20.9 per cent higher than in the previous year. Investments  
by business and industry will grow by 6.6 per cent this year and by about 2.5-3 
per cent annually during the next three years.                                  

Statistics Norway expects that Norges Bank's key interest rate (“sight deposit  
rate”) will rise by a percentage point to 5 per cent this year and that it will 
remain at that level for quite some time. The interest rate spread with the euro
will be about one percentage point at the end of the present year, which will   
strengthen the Norwegian kroner. Higher interest rates, stronger currency and a 
labour shortage in many sectors of the economy put the brakes on growth.        
Statistics Norway nevertheless expects the boom to continue until at least 2010 
and the unemployment rate to drop to 3 per cent. Inflation will remain under 2.5
per cent and growth in real incomes over a four-year period will total 15 per   
cent.                                                                           

Denmark                                                                         
                                                                                
The outlook for the Danish economy is still good. In January, Nordea anticipated
that GDP growth will amount to 2.1 per cent this year. Growth will slacken to   
1.5 per cent in 2008. Export growth gathered steam last year, and will continue 
at a rate of 6 per cent this year and 5.6 per cent the next. Growth in private  
consumption is estimated to slacken to 2.6 per cent in 2007. Investments will   
increase by 5.8 per cent during the present year. Housing prices rose by 23.9   
per cent last year, but growth will slow down to about 2.8 per cent this year   
and further the next. The rapid rise in prices has increased the supply of      
housing, as a result of which the housing market is returning to normal. At the 
beginning of April, the Danish Construction Association estimated that the      
number of new residential start-ups will be 30,500 this year and 28,500 the     
next, compared to 31,000 during the past two years. Growth in real incomes and  
full employment have strengthened the confidence of households in their own     
finances, which means opportunities in the demand for housing will remain good. 
Housing renovation will not see growth in these years. According to             
Euroconstruct, the construction of other types of new buildings will increase by
3.7 per cent this year, and by 3.8 and 3.9 per cent in 2008 and 2009.           

Baltic countries                                                                
                                                                                
GDP and investments grow at a significantly faster rate in Latvia, Lithuania and
Estonia than in the Nordic countries. According to VTT's estimate, the value of 
construction was EUR 5.8 billion in 2005. In April, IMF pegged Latvia's GDP     
growth in 2007 at 10.5 per cent. According to the IMF's forecast, GDP growth in 
Estonia will be 9.9 per cent and 7.9 per cent in 2007 and 2008, respectively,   
and 7 and 6.5 per cent in Lithuania. Inflation in Estonia is double the EMU     
average, and it is triple in Latvia. In this region, inflation is at its most   
moderate in Lithuania - about 3.5 per cent this year and the next. The growth of
these economies is supported by their high educational level and the EU         
membership of Estonia, Latvia and Lithuania. Growth in investments this year    
will be 14 per cent in Estonia, 18 per cent in Latvia and 15 per cent in        
Lithuania. In 2008, investments will continue to grow at a rate of over 10 per  
cent in these countries, and by as much as 17 per cent in Lithuania. Affordable 
borrowing, economic growth and the greater affluence of the population have     
increased demand for new residences and renovation in recent years. VTT         
estimates that a total of about 21,000 residential units will be completed in   
the Baltic countries this year. Building permits have been granted for over     
twice as many residences as have been completed.                                

Russia                                                                          

The high price of oil supports Russian economic growth. In January, Nordea      
estimated that Russia's GDP will grow by 6.5 per cent this year and by 6.0 per  
cent in 2008. At the beginning of April, the Ministry of Economic Development   
and Trade of the Russian Federation (MERT) nudged its GDP forecasts for         
2007-2010 up to 6.5, 6.1, 6 and 6.2 per cent, respectively. Russia has recently 
tapped its oil funds to accelerate the repayment of the government debt.        
Considering its currency reserves, Russia is now in practice a debt-free        
country. Last year, inflation was 9.7 per cent; according to Nordea's estimate, 
it will slow down to 8.7 per cent this year. Ministry of Finance of the Russian 
Federation, predicts that inflation will decline to 7.2 per cent this year. The 
rouble is expected to continue to strengthen. The rate of growth in investments 
will rise to 18 per cent this year and continue at a rate of 12 per cent the    
next, remaining significantly faster than the EU and Nordic average over the    
next few years. A significant share of investments is earmarked for residential 
construction.                                                                   

Thanks to the good incomes trend, household consumption has become the primary  
engine of growth. Private consumption will rise by 15 per cent this year,       
comprising half of GDP. The greater affluence of the middle class has           
strengthened demand for market-financed residences in large cities such as      
Moscow and St Petersburg. Last year, the prices of residences in some large     
cities saw an exceptional rise of 60-100 per cent due to the decline in supply. 
According to Rosstroi 50% more apartments were started-up during the first      
quarter of this year than the first quarter of 2006.                            

EARNINGS TRENDS OF THE BUSINESS SEGMENTS                                        
                                                                                
BUILDING SYSTEMS                                                                

Building Systems continued to improve its profitability and focused on revenue  
growth. The business segment's revenue in the January-March period was up 13 per
cent to EUR 367.7 million (Jan-Mar/2006: EUR 325.6 million). The share of the   
business segment's revenue accounted for by the maintenance and servicing       
business was 62 per cent (62%), or EUR 226.8 million (EUR 200.7 million).       

The business segment's operating profit increased by 61 per cent to EUR 18.8    
million (EUR 11.7 million). The operating profit margin improved to 5.1 per cent
(3.6%).                                                                         

The order backlog was at a record high, having grown by 30 per cent on the      
previous year to EUR 670.3 million (EUR 517.6 million).                         
                                                                                
The business segment had 11,569 employees (11,011) at the end of the period.

Good economic trends held steady in Sweden                                      

The state of the Swedish economy remained solid. Industrial output was on the up
and industrial companies are expected to start up major investments in the near 
future. It is expected that the trend in construction will be steady. Household 
consumption and the employment situation picked up yet again.                   

YIT signed agreements with the cities of Ludvika and Strängnäs for energy       
savings programmes covering city-owned properties. The programmes are geared    
towards reducing energy costs with total technical solutions.                   

An agreement was made with AstraZeneca for the assessment and upkeep of the     
building equipment systems of the Lund research station. Piping and equipment   
will be installed at the extension of a plant in Köping on behalf of the        
chemical company Yara.                                                          

Market situation remained solid in Norway                                       

The trend in the market for building system services remained favourable in     
Norway. Construction in the first months of the year was significantly more     
brisk than last year. However, there are great regional differences in the scale
of commercial premise construction. Demand for the modernization and renovation 
of commercial premises remained solid.                                          

The Norwegian Armed Forces made a three-year agreement with YIT for the upkeep  
of all its electrical systems in southern Norway. An order came in from         
Seabrokers Eiendom for a total technical solution for the Statoil office        
building in Stavanger. A total technical solution will be implemented in the    
office building of the Nistad group in Bergen.                                  

Demand for total technical solutions increased in Finland                       

The trend in the Finnish market for building equipment systems was favourable in
all types of services. In particular, there was growing demand for total        
technical solutions and supplementary special technology, such as security and  
refrigeration technology.                                                       

During the review period, a framework agreement was made with Metsä-Botnia for  
providing building system services for the company's mills in Finland. The      
agreement covers the servicing and upkeep of building systems as well as the    
technical maintenance of the building. Numerous agreements were made with UPM,  
such as for property upkeep, annual system servicing and the preventative       
servicing of building equipment systems in Lappeenranta, Kuusankoski and        
Kajaani. YIT made an agreement with the Social Insurance Institution of Finland 
KELA for the management of electrical equipment operation in six office         
buildings located around Finland in 2007-2010.                                  

A central building will be implemented for Kiinteistö Oy Ylläs Resort Center in 
association with YIT Construction Services. HEPACE works will be carried out at 
the leisure-time site YIT built in Vuokatti. HEPAC works will be performed at   
the Galleria shopping centre in Lappeenranta, and HEPACE and sprinkler works    
will be carried out at a Prisma hypermarket in Kuopio.                          

Outsourcing technical servicing and installation in Denmark                     

The state of the Danish economy remained good. The development of construction  
and industry is expected to level off slightly in the first half of the year.   
Demand for building systems and servicing continued to be solid in the          
construction of industrial and commercial facilities and in the case of public  
premises. It is expected that the public sector will start stepping up          
investments once the changes ushered in by the new regional and municipal       
divisions have been seen to completion. Outsourcing in the maintenance of the   
technical systems of properties and production plants is seeing steady growth as
companies focus on their core business.                                         

A long-term service agreement was made with Danish State Railways, covering the 
periodic maintenance and repairs of ventilation and cooling systems at all of   
the country's railway stations, as well as emergency duties. In Fredericia,     
Shell outsourced the maintenance and servicing of all its manufacturing
equipment systems to YIT. Cooperation with Grundfos was initiated with an
agreement on the maintenance of the automated gates of a plant in Bjerringbro.
YIT has agreed on numerous consulting deliveries regarding electrical systems
for production facilities with potentially explosive atmospheres with a view to
meeting EU directive requirements. 

Electrical and communication systems will be supplied for three ships being     
built in Odense on behalf of the Royal Danish Navy. F.L. Schmidt will be        
provided with full ventilation systems for manufacturing facilities, which will
be transported to Libya for installation. An agreement was also made with
Interxion for a large-scale installation delivery for a data room. 

Need for building system services raised in Estonia, Latvia, Lithuania and      
Russia                                                                          

The market for building system services is still developing buoyantly in the    
Baltic countries and especially in Russia. International investments are on the 
rise in YIT's business territories, increasing demand for building equipment    
systems and property management services.                                       

Long-term service agreements were extended to 2007 at the Mega and Akropolis    
shopping centres as well as Maxima chain stores in Lithuania, the Rimi office   
and logistics centre in Riga, Latvia as well as McDonald's restaurants, Rolf car
dealerships, the Mega-Chimki shopping centre and the Grundfos production plant 
in Moscow, Russia.                                                              

In Lithuania, building equipment solutions will be implemented for the telco TEO
LT's administration building in Vilnius, and HEPACE installation works for the  
entertainment and shopping centre YIT built in Panevezys. HEPACE and automation 
works got under way at an apartment building built by YIT in Moscow, Russia. 

CONSTRUCTION SERVICES                                                           

In the first months of the year, the revenue of Construction Services grew by 5 
per cent on the previous year and amounted to EUR 369.2 million (EUR 350.8      
million). The share of revenue accounted for by the maintenance business was 4  
per cent (4%), or EUR 15.1 million (EUR 12.3 million). Of the revenue, 77 per   
cent came from Finland, 12 per cent from Russia, 10 per cent from Estonia,      
Latvia and Lithuania, and less than one per cent from other countries.          

Operating profit stayed at last year's level and amounted to EUR 41.2 million   
(EUR 40.7 million). The operating profit margin remained excellent, 11.2 per    
cent (11.6%).                                                                   

The uninvoiced backlog of orders was at a record high. The order backlog was 65 
per cent higher than last year, amounting to EUR 2,137.9 million (EUR 1,296.5   
million).                                                                       

The business segment had 5,734 employees at the end of the period (5,118).      

Housing demand remained good                                                    

Demand for new apartments remained in good level in Finland and the prices of   
residences saw moderate growth. Prices soared in the Baltic countries and       
especially in Russia in 2006. The number of residences YIT sold in Russia       
decreased compared to the previous year, but the value of sales stayed the
same. 

In January-March, the average selling price of residences in Russia was about 49
per cent (27%) of the average selling price of the market-financed residences   
sold by YIT in Finland, and in the Baltic countries about 55 per cent (46%).    

The construction of leisure-time residences progressed in line with plans. The  
marketing of the Vuokatti, Tahko, Meri-Teijo and Sappee leisure-time projects   
was launched during the report period. The development of new leisure centres   
continued, with a particular focus on southern Finland.                         

During the review period, YIT made a preliminary agreement with SATO Oyj and    
YH-Suomi Oy for the sale of 42 residential units in St Petersburg. In addition, 
YIT sold 51 new apartments in the Greater Helsinki Area to SATO and YH-Suomi for
use as rental housing.                                                          

YIT estimates that it will start up more residences than last year              

YIT estimates that this year it will start up the construction of about 2,700   
market-financed residential units in Finland (start-ups in 2006: 2,818), about  
4,500 in Russia (3,699) and about 900 in the Baltic countries (887).            

The market outlook for the developer contracting of housing is estimated to     
remain solid in all of YIT's market areas. Factors such as the population shift 
and the improvement in the employment count maintain demand for housing in      
Finland. Consumers have a positive outlook on the development of their own      
finances and firm intentions to purchase housing in spite of the rise in the    
interest rate level. In Russia and the Baltic countries, strong economic growth,
the need to improve housing quality and the positive trend in household earnings
uphold the demand for residences. At the end of March, YIT had 244 completed    
unsold residential units in Finland. There were 5 completed unsold apartments in
Russia and none in the Baltic countries.                                        

YIT is stepping up residential construction in Russia by increasing start-ups in
its present territories and by expanding to the satellite cities of Moscow. Over
the next few years, YIT also aims to expand its operations into other Russian   
cities with populations in excess of a million.                                 

YIT currently builds housing in St Petersburg, Moscow, the Moscow Oblast,       
Yaroslavl and Yekaterinburg. The company also aims to start up residential      
construction in Kazan in 2007.

Plot reserves include plots that have been zoned and an estimate of the         
potential building rights on areas that are under zoning. Building rights       
provided by regional development agreements made with landowners are not        
included in YIT's balance sheet until the zoned sections are each in turn slated
for construction.                                                               

In land management in Finland, outlays were made on good plot reserves and their
rapid turnover as well as long-term regional development projects in cooperation
with landowners and municipalities. Plot reserves in Russia were bolstered      
vigorously in 2006 and these reserves were partly put to use during first months
of 2007. Plot reserves were also strengthened in Riga, Latvia, and in the       
Tallinn area and Tartu in Estonia.                                              

Good demand in office, commercial and logistics construction                    

In Finland, demand for new office premises remained good in the Greater Helsinki
Area and the general vacancy rate of premises declined. The market for retail   
and logistics premises also stayed good. New construction increased during the  
period. In addition, numerous property owners are converting office properties  
for other purposes, such as for use as housing and hotels. Construction         
investments by industry remained slight. In the case of tender-based contracts, 
the market remained tight, particularly in renovation.                          

In the first months of the year, YIT started up the construction of the         
extension of its head office in Käpylä, Helsinki Finland. The extension will be 
owned by RBS Nordisk Renting. The construction of the Duetto office building    
also got under way in Käpylä.                                                   

Preparatory works for the construction of Atria's production plant began in     
Gorelovo close to the international airport of St Petersburg. The construction  
of the last stage of the logistics project agreed with Genesta started up in    
Lithuania.                                                                      

Good market situation continues in infrastructure construction                  

Demand remained good in infrastructure construction. Agreements were made with  
Helsinki Water for the construction of the back-up connection of the Pitkäkoski 
water intake plant and with YTV for the construction of leachate equalization   
basins for the extension of the Ämmässuo landfill. An order came in from the    
municipality of Tuusula for the construction of the Kievari water tower.        

An agreement was made with the Romanian state to rehabilitate a drinking water  
treatment plant in the city of Drobeta.                                         

After the end of the period, YIT was handed the maintenance of roads in the     
Kulosaari, Herttoniemi and Laajasalo areas of Helsinki.                         

INDUSTRIAL AND NETWORK SERVICES                                                 

The revenue of Industrial and Network Services grew by 3 per cent to EUR 110.7  
million (EUR 107.7 million). The share of revenue accounted for by the          
maintenance business was 57 per cent (60%), or EUR 63.5 million (EUR 64.4       
million). Of the revenue, 93 per cent came from Finland and 7 per cent from     
other countries.                                                                

Operating profit was EUR 5.0 million (EUR 5.3 million) and the operating profit 
margin was 4.5 (4.9%). Favourable trends were seen in industrial projects and   
maintenance. The operating profit of the business segment decreased due to weak 
market for network services and the final completion of the downscaling measures
carried out in 2006. The remainder of the costs of the personnel cuts, EUR 1.0  
million, was recognized in operating profit in Q1 2007. Previously, YIT         
estimated that the additional costs that would be booked in early 2007 would    
amount to no more than about EUR 3 million. The bulk of the cost effects of the 
personnel cuts - EUR 5.1 million - was recognized in the Industrial and Network 
Services business segment's Q3 operating profit of 2006.                        

The order backlog at the end of the period grew by 4 per cent to EUR 228.8      
million (EUR 219.5 million). The order backlog in Network Services is based on  
forecasts from customers, which declined since the previous year.               
                                                                                
At the end of the period, the business segment had 4,787 employees (4,700).     

Demand for industrial maintenance services remained brisk                       

The utilization rate of industrial production plants has been high and demand   
for maintenance services remained brisk. YIT seeks growth especially from       
end-to-end maintenance partnership agreements, in which the company's           
responsibilities encompass the management and development of maintenance        
operations as well as operational upkeep.                                       

As from the beginning of the year, the maintenance of Botnia's pulp mills in    
Rauma and Äänekoski was transferred to YIT and Metsä-Botnia's joint venture     
Botnia Mill Service. The company now handles the end-to-end maintenance of all  
of Botnia's mills in Finland. Under the agreement, about 100 people transferred 
into Botnia Mill Service's employ.                                              

Market for industrial projects was favourable                                   

The market situation for capital investment projects for industry remained      
favourable. Numerous new deliveries were agreed on in the first months of the   
year.                                                                           

In Finland, an order came in from UPM for the delivery of bleaching plant piping
for the Tervasaari plants in Valkeakoski. A demanding high-pressure piping and  
equipment installation project will be carried out for Borealis Polymers Oy as  
part of the upgrading of ethylene and phenol unit efficiency. An agreement was  
made with Stora Enso for the implementation of ventilation solutions at the     
Varkaus mill and with Fortum Sähkönsiirto Oy for electric station modernization 
in Taalintehdas.                                                                

YIT and OAO Svetogorsk, which is owned by International Paper in Russia, agreed 
on a piping installation project for a PCTMB plant in Svetogorsk. An agreement  
was forged with Södra Cell in Sweden concerning the soda recovery boiler repair 
project at the Mörrum pulp mill. Orders came in from Andritz Oy for the delivery
of the internal circulation piping of a soda recovery boiler to ENCE in Spain,  
and from Foster Wheeler for the delivery of high-pressure piping for Votorantim 
Metais Niquel S.A. in Brazil.                                                   

During the review period, the projects for the Kymi REC 08 project at UPM's     
Kuusankoski plants were started up. In addition to high-pressure and process    
piping, tanks as well as electrical automation and ventilation works will be    
supplied for the plant during the present year. Piping for a combined cycle gas 
power plant was implemented as a turnkey project for Siemens AG in Kårstö,      
Norway.                                                                         

Market for network services is still tight                                      

The market situation in field services for teleoperators continued tight. The   
market is still impacted by the waning demand for broadband connections.        

At the beginning of the year, YIT ventured into energy network services by      
making a partnership agreement with Vattenfall Verkko Oy. Under the agreement,  
the electricity network maintenance, repair and construction works that had     
until then been handled by Vattenfall were handed over to YIT. About 100        
Vattenfall Verkko employees transferred to YIT. By partnering up with           
Vattenfall, YIT became a significant player in the growing market for           
electricity network construction and maintenance.                               

EVENTS AFTER THE END OF THE REVIEW PERIOD                                       

On April 2, 2007, YIT Industrial and Network Services Oy acquired T. Kanerva Oy,
the only Finnish supplier of special seals used in the process and energy       
industry. T. Kanerva Oy's personnel transferred into YIT's employ under their   
current terms of employment. Its engineering workshop will continue to operate  
in Piikkiö.                                                                     

The Series F share options issued in 2004 and the Series K and L share options  
issued in 2006 were made available for trading on the Main List of the Helsinki 
Stock Exchange as from April 2, 2007.                                           

The annulment of the 400 YIT Corporation shares in the company's possession was 
entered in the Trade Register on April 10, 2007.                                

OUTLOOK FOR 2007                                                                

We estimate that revenue and operating profit (EBIT) in 2007 will increase      
compared to the previous year.                                                  

The outlook for revenue growth is supported by the record-high order backlog,   
the continuing boom and YIT's major investments in the Russian market. The      
healthy margin of the order backlog and the company's own profitability         
improvement measures underlie our expectations of growth in operating profit.

ACCOUNTING PRINCIPLES OF THE INTERIM REPORT                                     

YIT Corporation's Interim Report for January 1 - March 31, 2007 has been drafted
in line with IAS 34: Interim Financial Reporting. YIT has applied the same      
accounting policy in the drafting of the Interim Report as in its annual        
financial statements for 2006. The information presented in the Interim Report  
has not been audited.                                                           

Application of amended IFRS standards or interpretations as from January 1, 2007
The Group has applied the following amendments to the standards or new          
interpretations as from January 1, 2007:                                        
IFRS 7 Financial Instruments: Disclosures. The standard mainly affects the scope
of the notes to the financial statements.                                       
IAS 1 (Amendment) Presentation of Financial Statements - Capital Disclosures.   
The amendment of the standard did not have an effect on this Interim Report.    
IFRIC 10 Interim Financial Reporting and Impairment. The application of the     
interpretation did not have an effect on this Interim Report.                   

BUSINESS SEGMENT STRUCTURE                                                      
YIT's business operations are divided into three business segments: Building    
Systems, Construction Services and Industrial and Network Services.             

FINANCIAL RISK MANAGEMENT                                                       

Foreign exchange risk                                                           

During the review period the Board of Directors amended the management of       
foreign exchange risk such that YIT Group's shareholders' equity in the home    
currency is no longer hedged against changes in foreign exchange rates.         

Foreign exchange positions are reported to the Audit Committee ones per year.

Terms of the bonds raised during the review period in brief:                    
1) Loan-period March 26, 2007 - March 26, 2014, interest payments by quarter in 
arrear, starting on June 26, 2007. The bond is unsecured. ISIN code             
FI0003024216. Interest rate is 3 months Euribor + 0.51%. (Private placement)    
2) Loan-period February 29, 2007 - March 29, 2012, interest payments by quarter 
in arrear, starting on June 29, 2007. The bond is unsecured. ISIN code          
SE0001991068. Interest rate is 3 months Euribor + 0.40%. (Private placement)    

Interest rate risk management connected to loans                                

Interest rate swaps are designated as hedges of floating rate loans: 3 month    
Euribor-linked loan                                                             
with carrying value of EUR 225 million and 6 month Euribor-linked loan with     
carrying value of                                                               
EUR 45 million. These hedges qualify for effective hedging requirements and     
changes in fair value are, according to company accounting principles,          
recognized in fairvalue reserve. The weighted average rate of the whole loan    
portfolio is raised by 0.057 percentage point via interest rate swaps.          

The duration of long term loans and derivative instruments hedging these loans  
was 1.64 years at the end of the review period (1.52 years on December 31,      
2006). A change of one percentage point in the interest level would March 31,   
2007 have affected the annual net financial expenses by EUR 2.9 million (EUR 4.1
million on December 31, 2006).
