YIT'S INTERIM REPORT, JANUARY 1  - SEPTEMBER 30, 2008:                          
REVENUE INCREASED, OPERATING PROFIT DECREASED                                   

In January-September:                                                           
- Revenue increased by 8 per cent to EUR 2,889.0 million (1-9/2007: EUR 2,679.5 
million).                                                                       
- Operating profit decreased by 7 per cent to EUR 212.2 million (EUR 229.1      
million).                                                                       
- The operating profit margin was 7.3 (8.6%).                                   
- Profit before taxes decreased by 9 per cent to EUR 187.8 million (EUR 207.1   
million).                                                                       
- Earnings per share decreased by 15 per cent to EUR 1.02 (EUR 1.20)            
- Return on investment was 21.9% (25.8%).                                       
- The order backlog increased by 25 per cent to EUR 3,964.9 million (EUR 3,172.5
million).                                                                       
- The number of personnel at the end of September was more than 2,800 higher    
than a year earlier, i.e. 26,688 (23,836).                                      

In the third quarter:                                                           
- Revenue was 7 per cent higher than in the previous year, amounting to EUR     
970.8 million (7-9/2007: EUR 906.8 million).                                    
- Profit before taxes decreased by 31 per cent to EUR 56.9 million (EUR 82.4    
million).                                                                       

- In January-September, demand for building system and industrial services, as  
well as civil engineering, remained good. In Russia, residential sales remained 
favourable throughout the review period. In St. Petersburg additional costs were
recognised for the real estate development projects underway in the Gorelovo    
area due to the implementation of the area's infrastructure. In Finland,        
residential sales faced a downturn after the summer. In the Baltic countries    
construction has decreased considerably. Service and maintenance operations     
accounted for more than one third of our revenue, balancing the impact of       
economic fluctuations," says President and CEO Hannu Leinonen.                  

- In the autumn, the financial market crisis had an impact on our area of       
operations. Investment decisions have been postponed and consumer confidence has
weakened. In Russia, tightening loan terms for companies made actors accelerate 
their residential sales; this stopped the increase in prices that had continued 
steadily for a long time. In the last few weeks, the residential sales in Russia
have weakened considerably.                                                     

"We have taken measures to adjust our operations to the market outlook. We have 
decreased residential start-ups in Finland. In Russia we made a decision after  
the review period to stop the construction of several residential projects whose
sales have not yet begun. Plot acquisitions and other investments have been     
stopped, and cost structure is resolutely being modified. In addition to        
strengthening operational cash flow, the Group's financial position is secured  
with pension insurance company loans, among other things. The objective is to   
ensure the Group's operational resources if the weak market situation becomes   
prolonged, as well as the resources for continuing profitable growth once the   
situation is over," Leinonen continues.                                         

Outlook for 2008                                                                

YIT estimates that revenue for 2008 will increase, but profit before taxes will 
decrease clearly compared to the previous year.                                 

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 and International         
Construction Services is estimated to decrease clearly during the last quarter  
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.                                                    

The estimate of profit development has been specified following the profit      
warning released on September 8, 2008. At that time, YIT estimated that the     
company's revenue will increase in 2008, but profit before taxes will decrease  
compared to the previous year. At the same time, YIT stated that the estimate on
profit development has weakened, because residential demand in Finland and      
construction volumes in the Baltic countries have decreased further.

YIT CORPORATION'S INTERIM REPORT, JANUARY 1  - SEPTEMBER 30, 2008               

STRATEGIC FOCUS AREAS                                                           

At the end of the review period, YIT Group's strategic focus was shifted to     
strengthening cash flow, modifying the cost structure and securing the financial
position after the economic situation and the global financial market crisis had
an impact on YIT's operating countries. The objective is to ensure the Group's  
operational resources if the weak market situation becomes prolonged, as well as
the resources for continuing profitable growth once the situation is over. YIT  
has initiated several fast-acting measures. Residential start-ups are being     
decreased and postponed. In Russia a decision was made after the review period  
to stop the construction of several residential projects whose sales have not   
yet begun. In real estate development projects, preparations were made to make  
new contractual arrangements in order to secure financing for the projects. Plot
acquisitions and other investments have been stopped. The aim is to cut fixed   
costs by EUR 40 million at an annual level. Procurement activities will be made 
more effective by adjusting purchase agreements to match the market situation.  

Long-term strategic target levels are: annual revenue growth 10 per cent on     
average, the operating profit 9 per cent of revenue, the return on investment 22
per cent, the equity ratio 35 per cent and the dividend payout 40-60 per cent of
annual earnings after taxes and minority interest. In addition, YIT has set a   
separate target of increasing its revenue in Russia by 50 per cent on average in
2006-2009. In Russia, the number of residential start-ups is adjusted on market 
terms based on the development of residential sales.                            

REVENUE INCREASED BY 8 PER CENT                                                 

YIT Group's revenue for January-September increased by 8 per cent on the        
previous year to EUR 2,889.0 million (1-9/2007: EUR 2,679.5 million). Building  
Systems is the largest segment by revenue. The revenue of both Building Systems 
and International Construction Services increased.                              

Finland accounted for 49% of revenue (53%), other Nordic countries for 33%      
(33%), Russia for 11% (8%), the Baltic countries for 5% (6%) and Central Europe 
for 2%. The fastest growth took place in Russia, where revenue increased by 53% 
to EUR 310.9 million (EUR 203.4 million). The Central European business         
operations acquired from Germany, Austria, Poland, Czech Republic, Hungary and  
Romania were transferred to YIT on August 1, 2008.

1) The business operations acquired from Central Europe were transferred to YIT 
on August 1, 2008. In August-September 2008 the revenue of these operations was 
EUR 58.6 million.                                                               
2) The figures for 1-9/2007 include the Network Services division, which was    
sold on December 31, 2007. Network Services revenue for 1-12/2007 amounted to   
EUR 77 million.                                                                 

YIT's service chain covers the entire life cycle of the investment. This enables
more comprehensive service deliveries and supports the stability of business    
operations. Service and maintenance of buildings, industry and traditional      
infrastructure - operations that are not so sensitive to economic fluctuations -
account for a significant proportion of the Group's revenue. Service and        
maintenance operations have increased and the share of the maintenance and      
servicing business has remained stable while the Group's revenue has grown. In  
January-September, service and maintenance operations generated EUR 1,012.7     
million (EUR 963.5 million), in other words 35% (36%) of total revenue.         

OPERATING PROFIT DECREASED BY 7 PER CENT                                        

The Group's operating profit decreased by 7 per cent to EUR 212.2 million (EUR  
229.1 million). The operating profit margin was 7.3 (8.6%). The return on       
investment was 21.9% (25.8%).                                                   

Operating profit and profitability improved at both Building Systems and        
Industrial Services. The operating profit of International Construction Services
weakened. In the Baltic countries weak market development continued. During the 
second quarter expenses were recognised in the operating profit of International
Construction Services due to the delay in the real estate development projects  
in the Gorelovo area. In the third quarter additional costs amounting to        
approximately EUR 13 million were recognised for the projects in the Gorelovo   
area due to an increase in the costs of the implementation of infrastructure in 
the area and specifications made on their allocation. In Construction Services  
Finland the operating profit decreased from the previous year.

1) The business operations acquired from Central Europe were transferred to YIT 
on August 1, 2008.                                                              
2) The Supreme Court issued its ruling on disputes connected with the renovation
of SOK's former head office building on March 10, 2008. The ruling had a        
positive effect of EUR 3.5 million on the operating profit of Construction      
Services Finland for Q1/2008.                                                   
3) The operating profit of Industrial Services in Q1/2007 includes a loss of EUR
1.0 million due to costs from the restructuring of the Network Services         
division. The Network Services division was divested on December 31, 2007.      

PROFIT BEFORE TAXES DECREASED BY 9 PER CENT                                     

Profit before taxes decreased by 9 per cent to EUR 187.8 million (EUR 207.1     
million). Earnings per share decreased by 15 per cent and was EUR 1.02 (EUR     
1.20).                                                                          

Financial expenses increased as a result of higher interest rates, increased    
loans and an increase in the amount of capital invested in Russia.              

THE ORDER BACKLOG GREW BY 25 PER CENT                                           

The Group's order backlog is high. At the end of the review period, the order   
backlog was 25% larger than the year before, reaching EUR 3,964.9 million (EUR  
3,172.5 million). At the end of June 2008, the order backlog amounted to EUR    
3,670.4 million.                                                                

The International Construction Services segment accounts for the majority of the
order backlog, due to the long duration and high value of the projects. In      
Russia, the duration of housing projects is approximately twice as long as in   
Finland. Residential development accounts for the majority of the order backlog 
of International Construction Services. The order backlog of Construction       
Services Finland is divided evenly between different business areas. The order  
backlog of International Construction Services grew the fastest.                

In Russia a decision was made after the review period to stop the construction  
of several residential projects whose sales have not yet begun. These projects  
have about 2,400 residential units and they account for approximately EUR 320   
million in the order backlog.

1) The business operations acquired from Central Europe were transferred to YIT 
on August 1, 2008.                                                              
2) The order backlog of 9/2007 includes the Network Services division, which was
sold on December 31, 2007.                                                      

The order backlog includes that portion of customer orders and ongoing          
development projects that has not been entered as income. In accordance with the
IFRS accounting principles, residential development projects are recognised as  
income using the formula percentage of completion multiplied by percentage of   
sale. Business premises development projects are recognised as income using the 
principle percentage of completion multiplied by percentage of sale multiplied  
by occupancy rate. Projects are recognised as income based on the percentage of 
completion.                                                                     

The order backlog of the Construction Services Finland and International        
Construction Services segments comprises contracting production and real estate 
and residential development with a sales risk. Contracted projects are sold in  
full. Business premises development projects are sold to investors usually      
either prior to construction or during an early phase thereof.                  

61 per cent of Building Systems revenue and 48 per cent of Industrial Services  
revenue are derived from steadily developing service and maintenance operations.
Due to their nature, part of the maintenance and servicing operations are not   
included in the order backlog. The remainder of the order backlog of these      
business segments mainly comprises contracted projects that have been sold in   
full.                                                                           

THE GROUP'S FINANCIAL POSITION REMAINED BALANCED                                

The Group's financial position remained balanced and liquidity remained good. A 
significant part of YIT's business operations require little capital. Capital   
was particularly tied up in the plot reserves, their development and ongoing    
production. During the third quarter, measures were initiated to limit the      
increase in working capital and to strengthen cash flow with pension insurance  
company loans, among other things. Commitment of capital into plots and ongoing 
production was limited.                                                         

The gearing ratio was 82.5 per cent (79.1%). Net debt increased to EUR 696.9    
million (EUR 591.4 million). In April the company paid EUR 101.8 million (March 
2007: EUR 82.6 million) in dividends.                                           

Net financial expenses during the period were EUR 24.4 million (EUR 22.0        
million), or 0.8 per cent (0.8%) of revenue. Net financial expenses in          
January-September 2008 include exchange rate profits and losses a total of EUR  
2.6 million (EUR -1.2 million) and in July-September 2008 a total of EUR 6.0    
million (EUR 0.5 million).                                                      

The proportion of fixed-interest loans in the Group's entire loan portfolio was 
45 per cent (66%). Loans raised directly on the capital and money markets       
amounted to 55 per cent (58%).                                                  

The construction-stage contract receivables sold to financing companies totalled
EUR 373.5 million (EUR 250.4 million) at the end of the period. Of this amount, 
EUR 97.2 million (EUR 104.8 million) is included in interest-bearing 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 11.8  
million (EUR 8.0 million), is included in financial expenses in its entirety.   

Participations in the housing corporation loans of unsold completed residences, 
EUR 37.7 million (EUR 36.7 million), are also included in interest-bearing      
liabilities, but the interest on them, EUR 1.5 million (EUR 1.2 million), is    
booked in project expenses, as said interest is included in housing corporation 
maintenance charges.                                                            

Interest-bearing liabilities included EUR 1.3 million in leasing commitments    
(EUR 1.9 million).                                                              

Due to the distributed nature of the maturity structure of debt, YIT has only   
limited refinancing needs during the fourth quarter of this year and in 2009. Of
long-term loans a bond of EUR 75 million will mature in December 2008 and a bond
of EUR 50 million in October 2009. A more detailed account is published in the  
notes to the 2007 financial statements in the Annual Report.                    

The balance sheet total at the end of the review period was EUR 2,868.5 million 
(EUR 2,418.4 million).                                                          

The Group's equity ratio was 33.4 per cent (33.8%).                             




CAPITAL EXPENDITURES AND ACQUISITIONS                                           

Gross capital expenditures on non-current assets included in the balance sheet  
totalled EUR 76.9 million (EUR 33.5 million) during January-September,          
representing 2.7 per cent (1.3%) of revenue. Investments in construction        
equipment amounted to EUR 11.3 million (EUR 11.0 million), and investments in   
information technology to EUR 4.2 million (EUR 4.4 million). Other investments, 
including acquisitions, amounted to EUR 61.4 million (EUR 18.1 million).        
Acquired and divested business operations are indicated in the tables section of
the 1-9/2008 interim report.                                                    

The most significant business acquisition during the period took place in       
Building Systems with the purchase of MCE AG's building system service          
operations in Germany, Austria, Poland, the Czech Republic, Hungary and Romania.
These operations' revenue for 2007 amounted to EUR 355 million. The purchased   
operations employ about 1,900 people. The value of the transaction was EUR 55   
million. The transaction was finalised on August 1, 2008.                       

CHANGES IN ORGANISATION                                                         

YIT Group's business segment structure was revised as of the beginning of 2008, 
with Construction Services being divided into two segments: Construction        
Services Finland and International Construction Services, which includes        
business operations in Russia, in the Baltic countries and in Central Eastern   
Europe.                                                                         

The Industrial and Network Services segment was renamed Industrial Services when
the sale of the Network Services division was completed on December 31, 2007.   

CHANGES IN GROUP MANAGEMENT

RESOLUTIONS PASSED AT THE ANNUAL GENERAL MEETING                                

YIT Corporation's Annual General Meeting was held on March 13, 2008. The Annual 
General Meeting adopted the 2007 financial statements, discharged the members of

Directors on March 13 and 14, 2008.                                             

YIT Corporation held an Extraordinary General Meeting after the review period on
October 6, 2008. The meeting decided to authorise the Board of Directors to     
purchase the company's shares and to dispose of them, as proposed by the Board  
of Directors. The authorisation granted to the Board of Directors covers 10% of 
the company's shares, i.e. the acquisition of a maximum of 12,722,342 company   
shares, purchased with the company's unrestricted equity, and the disposal of   
the shares according to conditions described in more detail elsewhere. YIT      
Corporation published a stock exchange release on the resolutions passes at the 
Extraordinary General Meeting on October 6, 2008.                               

LEGAL PROCEEDINGS                                                               

On March 10, 2008, the Supreme Court in Finland announced its ruling regarding  
the disputes arising from the refurbishing of SOK's former head office,         
Kiinteistö Oy Vilhonkatu 7, which was completed in 1999. The ruling had a       
positive effect of EUR 5.7 million on YIT's profit before taxes. The sum was    
recognised in full in YIT's result for January-March 2008.                      

The disagreement that has arisen in the final financial settlement for the      
mechanical installation works on production line 4, which was completed at Neste
Oil's Porvoo oil refinery in Finland in the summer of 2007, was submitted to the
court of arbitration in April 2008. In September, Neste Oil specified its claims
against YIT Industrial and Network Services in the court of arbitration         
proceedings by also claiming compensation for lost production. Neste Oil's total
claims amount to a total of EUR 107 million. YIT is contesting Neste Oil's      
claims and has presented claims against Neste Oil, mainly based on the          
alterations and additional work performed, and the additional costs that arose  
from the prolongation of the contract. YIT published stock exchange releases    
concerning the matter on April 1, 2008 and September 1, 2008.                   

THE NUMBER OF PERSONNEL INCREASED                                               

The Group employed an average of 24,278 (23,176) people during the period under 
review. At the end of the period, the Group employed 26,688 (23,836) people. Of 
YIT's employees, 40 per cent work in Finland, 34 per cent in the other Nordic   
countries, 13 per cent in Russia, 8 per cent in Central Europe and 5 per cent in
the Baltic countries. The number of personnel has increased considerably in     
Russia, in particular. The Group aims to ensure the availability of competent   
employees.

1) The business operations acquired from Central Europe were transferred to YIT 
on August 1, 2008.                                                              

Demand for technical building systems levelled off                              

Demand for building system services levelled off in the Nordic countries and    
Russia and decreased in the Baltic countries. In Central Europe the demand      
continued good as a whole.                                                      

The implementation of building systems was agreed, for example, ín Sweden with  
the SCA Graphic paper mill in Sundsvall, Scania's canteen and Fabege for a      
shopping centre located outside Stockholm, in Finland with the Sokos centre in  
Jyväskylä and the Teollisuuskatu 21 repair and renovation site in Helsinki, and 
in Denmark with the logistics centre of the JYSK house equipment chain in Uldum.
In Norway, the implementation of total technical solutions in a school in       
Sogndal was agreed with the construction company Aase & Øvrelid, and an         
agreement was signed with Statsbygg on the security systems of a new prison. In 
Germany orders were received among others for total technical solution delivery 
in multipurpose building AirRail at Frankfurt Airport, in Poland total HVAC     
deliveries for IKEA megastore and local headquarters of Strabag in Warsaw, in   
Austria wide high voltage power supply system in surroundings of Vienna city and
power supply solution delivery for Wien Mitte -railway station and in Hungary a 
total HVAC solution delivery for Budawest -office complex in Budapest.          

Demand for service agreements remained good                                     

In the Nordic countries and Russia, the demand for building technical repair and
maintenance works and various service agreements remained stable. Also in       
Central Europe the demand for building technical repair and maintenance works   
was good.                                                                       

Service and maintenance agreements pursuant to the ServiFlex concept were signed
in Norway with the public as well as private sectors. In Finland, a framework   
agreement on security technology and related services was agreed with Hansel Oy.
In Denmark, Odense Steel Shipyard A/S outsourced technical maintenance          
operations to YIT.                                                              

Growing demand for energy services                                              

Demand for energy-efficient technical building systems is increasing and there  
is more willingness to invest in alternative forms of energy in order to slow   
down climate change. The improvement in the energy efficiency of existing       
building stock is boosting the number of repair and modernisation projects and  
the need for real estate services.                                              

Agreements were concluded in several Swedish and German cities on energy        
inspections of buildings. In Finland a building system development programme    
named CoolHeat is underway in cooperation with Tekes (the Finnish Funding Agency
for Technology and Innovation) and corporate partners, aiming to improve real   
estate energy efficiency by developing building system solutions for existing   
buildings as well as low-energy construction. In Norway, several energy saving  
projects have been initiated within the framework of the ENOVA agreement,       
entitling the signatory to receive state funding. In Denmark, YIT is negotiating
energy investments particularly in the municipal sector, where demand for energy
investments has increased.                                                      

CONSTRUCTION SERVICES FINLAND                                                   

In January-September:                                                           
- Construction Services Finland's revenue remained at the previous year‘s level

- The order backlog remained at the previous year‘s level and amounted to EUR   
1,085.9 million (EUR 1,128.9 million).                                          
- Construction Services Finland's capital tied into plot reserves amounted to   
EUR 337.5 million (EUR 332.2 million) at the end of September.                  
- At the end of September, the segment employed 3,408 people (3,509).           

In the third quarter:                                                           
- Construction Services Finland's revenue was EUR 285.8 million (EUR 272.5      
million).                                                                       
- Operating profit decreased by 16 per cent to EUR 28.1 million (EUR 33.4       
million).                                                                       

The figures for 2007 are comparison figures calculated after the business       
segment structure changed on January 1, 2008.                                   

The Supreme Court issued its ruling on disputes connected with the renovation of
SOK's former head office building on March 10, 2008. The ruling had a positive  
effect of EUR 3.5 million on the operating profit of Construction Services      
Finland for Q1/2008.                                                            

Business premise construction continued                                         

The construction of ongoing business premises projects continued. No new        
property development projects were started during the third quarter.            

Property development projects underway included among others the construction of
the Maalitori office building in Vantaa, business premises at Graanintie 6 in   
Mikkeli and the second and third phases of the Koskelo Trade Park in Espoo. In  
September, an agreement was signed according to which YIT will sell the Koskelo 
Trade Park to the German company Hansainvest. In addition, an agreement was     
signed on the construction project of the Lammin Liikuntakeskus sports centre.  

Residential sales decreased compared with last year                             

The number of residences sold decreased in January-September compared with last 
year. The value of residential sales remained at the same level during the first
two quarters. Residential sales decreased during the third quarter, as did their
value. Uncertainties connected to general market conditions are weakening the   
outlook for housing construction for the last quarter.                          

A total of 1,326 (2,091) residential units were sold in Finland in              
January-September, 1,126 (1,903) were started and 1,792 (2,322) were completed. 
At the end of September, there were 2,143 (2,977) residential units under       
construction and 329 (299) completed but unsold residential units.              

All YIT Homes planned in 2008 or later will be built as low-energy buildings.   
The construction of YIT's first low-energy buildings was started in Siilinjärvi 
and Mikkeli.                                                                    

Joint land use planning and subsequent purchase of the Lepola land area was     
agreed upon in Järvenpää with Seurakuntaopisto. It will be possible to construct
10,000 square metres of floor area in the area.                                 

Good demand in civil engineering                                                

Demand for the construction of infrastructure remained good. Significant        
investments in traffic infrastructure are expected over the next few years.     

During the review period, an agreement was signed with Helsinki Energy on the   
excavation and structural work of the Meilahti-Pasila joint-use tunnel, and with
Finavia on earth moving, bearing and concrete structure work at the             
Helsinki-Vantaa Airport Central Terminal.                                       

YIT and the city of Mikkeli established a joint venture, YIT Kuntatekniikka Oy, 
which will construct, develop and maintain infrastructure and provide services  
related to the technical infrastructure in the Mikkeli economic area and the    
Province of Eastern Finland.                                                    

INTERNATIONAL CONSTRUCTION SERVICES                                             

In January-September:                                                           
- International Construction Services' revenue increased by 19 per cent on the  
previous year to EUR 397.1 million (EUR 334.1 million).                         
- Operating profit decreased by 60 per cent to EUR 18.2 million (EUR 45.5       
million).                                                                       
- The operating profit margin decreased to 4.6 (13.6%).                         
- The order backlog increased by 48 per cent to EUR 1,678.2 million (EUR 1,134.4
million).                                                                       
- International Construction Services' capital tied up in plot reserves amounted
to EUR 244.0 million (EUR 211.3 million) at the end of September.               
- At the end of September, the segment employed 3,717 people (2,885).           

In the third quarter:                                                           
- International Construction Services' revenue decreased by 12 per cent to EUR  
123.3 million (EUR 139.6 million).                                              
- Operating result was EUR -4.0 million (EUR 23.9 million).                     

The figures for 2007 are comparison figures calculated after the business       
segment structure changed on January 1, 2008.                                   

The operating profit of International Construction Services weakened. In the    
Baltic countries weak market development continued. During the second quarter   
expenses were recognised in the operating profit of International Construction  
Services due to the delay in the real estate development projects in the        
Gorelovo area. In the third quarter additional costs amounting to approximately 
EUR 13 million were recognised for the projects in the Gorelovo area due to an  
increase in the costs of the implementation of infrastructure in the area and   
specifications made on their allocation.                                        

The agreement on a business acquisition in the Czech Republic signed by YIT     
Construction Ltd on May 29, 2008 entered into force on July 1, 2008. The        
transaction gave YIT a foothold in a new market area in line with YIT's         
strategy.

In Russia, residential sales continued to be good                               

In Russia, residential sales continued to be good in the review period. During  
the third quarter, residential sales were on the same level with the previous   
quarters. Towards the end of the review period, tightening loan terms for       
companies made actors accelerate their residential sales; this stopped the      
increase in prices that had continued steadily for a long time. In some areas   
the prices started to decrease. The general market development causes           
uncertainty in the housing construction outlook in the last quarter. The        
positive income trends of households and the need to improve the quality of     
living will support the demand for housing in the long term.                    

In Russia, 2,494 (1,168) residential units were sold, 3,622 (1,510) were started
and 1,712 (1,258) were completed. At the end of September, there were 11,768    
(7,320) residential units under construction. There were 192 (13) completed but 
unsold residential units. Slight changes in the number of residential units may 
take place after the start of construction due to the division or combination of
residences.                                                                     

Due to uncertainties in the economic situation YIT made a decision in Russia    
after the review period to stop the construction of several residential projects
whose sales have not yet begun. These projects have about 2,400 residential     
units and they account for approximately EUR 320 million in the order backlog.  
When the market situation normalises, YIT will immediately be able to increase  
the number of residential units on sale particularly in St. Petersburg and in   
the Moscow area.                                                                

In addition to St. Petersburg, cities in the Moscow region and Moscow, YIT has  
ongoing housing development projects in Yaroslavl, Yekaterinburg, Rostov-on-Don 
and Kazan.                                                                      

Permits for putting into operation the Gorelovo logistic centres                

The property development projects in the Gorelovo area in St. Petersburg,       
Russia, entered the final phase. In September, the local authorities granted YIT
the official permits for putting into operation the Gorigo logistics centre in  
the Gorelovo industrial park. The centre consists of two large logistics        
buildings with a total area of about 91,000 m2. YIT was also granted the permits
for putting the Atria logistics centre in Gorelovo into operation. The food     
plant being built in the area requires the building technical solution and the  
implementation of the final water and drain connections before it can be put    
into operation.                                                                 

In the Moscow region, YIT acquired a few new plots from the city for residential
production and business premises construction. In order to commence the         
construction of business premises, a company named ZAO YIT Properties was       
established in the Moscow region.                                               

Weak market development continued in the Baltic countries                       

The market development in the Baltic countries continued to be poor. The markets
were weak in Estonia, Latvia and Lithuania. Demand for housing remained low and 
the activities of construction companies have focused on tender-based contracts.
The overall volume of construction has decreased significantly.                 

In Lithuania, the construction project of a large office site has been postponed
into the future due to a complaint made against the project. In another         
significant project, work has been suspended due to the client's financing      
shortage.                                                                       

YIT has been actively pursuing a decrease in the number of unsold residential   
units. There have been no new housing start-ups. In January-September, 689 (346)
residential units were sold in Lithuania, Estonia and Latvia, 0 (506) were      
started and 487 (600) were completed. At the end of September, there were 841   
(1,779) residential units under construction. There were 97 (2) completed but   
unsold residential units.                                                       

INDUSTRIAL SERVICES                                                             

In January-September:                                                           
- Industrial Services' revenue amounted to EUR 310.5 million (EUR 359.0         
million).                                                                       
- Service and maintenance operations accounted for 48% (58%) of revenue.        
- Finland accounted for 89 per cent of revenue, Russia for 2 per cent and       
England, Sweden and other export countries for 9 per cent.                      
- Operating profit increased by 14 per cent to EUR 21.5 million (EUR 18.9       
million).                                                                       
- The operating profit margin improved to 6.9% (5.3%).                          
- At the end of September, the order backlog was EUR 238.0 million (EUR 221.7   
million).                                                                       
- At the end of September, the segment employed 3,672 people (4,593).           

In the third quarter:                                                           
- Industrial Services' revenue amounted to EUR 108.7 million (EUR 118.7         
million).                                                                       
- Operating profit was EUR 7.8 million (EUR 8.1 million).                       

The figures for 2007 include the figures for the Network Services division,     
which was sold on December 31, 2007. Network Services' revenue for 1-12/2007 was
EUR 77 million. The operating profit for 1-3/2007 includes EUR -1.0 million due 
to restructuring of the Network Services unit. Approximately 1,000 people left  
YIT as a result of the divestment of Network Services.                          

Solid demand for industrial maintenance services                                

Demand for maintenance services remained good. Maintenance agreements were      
extended with UPM's Seikku sawmill and Altia's Rajamäki factory. The agreement  
on the annual maintenance of the Loviisa nuclear power plant was renewed with   
Fortum. An agreement on the servicing of relief valves was made with Borealis.  

Shutdown maintenance was carried out in, for example, Teollisuuden Voima's      
Olkiluoto nuclear power plant, Fortum's Loviisa nuclear power plant and Meripori
power plant, Stora Enso's Oulu mill, Kemiart Liners' mill in Kemi and all of    
Botnia's pulp mills in Finland.                                                 

Investments in the energy, steel and mining industry continued                  

Demand for industrial projects remained good in the energy, steel and mining    
industries. The forest industry has decreased its investments.                  

Deliveries of pipe systems were agreed with, for example, Fortum's Suomenoja    
gas-combi plant and Jyväskylän Energia's biopower plant. Among steel companies, 
an agreement on the renewal of electricity distribution and pipeline deliveries 
was made with Rautaruukki, and one on a process electrification project at the  
Tornio steel mill with Outokumpu Steel.                                         

Interest in energy efficiency is on the rise in Finnish industry. New           
comprehensive energy-saving projects have been conducted, for example with      
Kemira Pigments and Ovako Wire.                                                 

Machine and equipment installations will be delivered to the SaratovStroiSteklo 
glassworks in Russia. Siemens AG ordered a significant total delivery comprising
design, material acquisition, prefabrication and installation at the Severn     
Power gas-combi plant in Uskmouth, United Kingdom.

MARKET SITUATION IN OCTOBER                                                     

The world economy is in a downturn. Economic growth is being slowed by tightened
crediting policies and high interest rates following the financial crisis, among
other things. At the beginning of October, the IMF estimated the euro area's GDP
to increase by 1.3% in 2008 and by 0.2% in 2009. A gradual recovery is estimated
to begin at the end of 2009.                                                    

According to Nordic building industry associations, the number of housing       
investments will decrease this year in all Nordic countries, and remain at a low
level next year. Other construction investments will decrease more significantly
in 2009. House renovation activity and energy saving investments will experience
steady growth. Market conditions in civil engineering remain positive.          

In October, the IMF projected real growth in Russia to amount to 7% this year,  
slowing down to 5.5% in 2009. Housing construction increased by a mere 5% on the
year before in January-August. In recent months, the increase in housing prices 
has cooled down and in some areas prices have started to decrease. Economic     
growth in the Baltic countries weakened considerably during the first two       
quarters. Next year the average growth in the Baltic countries as a whole is    
estimated to be negative.                                                       

In Germany and Austria, the economic growth will be approximately 2% this year, 
but will barely be positive in 2009. In Central Eastern European countries      
growth estimates are still clearly positive, but the account deficits and the   
European downturn already weaken the economic development.                      

MAJOR BUSINESS RISKS AND UNCERTAINTIES IN THE NEAR FUTURE                       

The most significant short-term business risks and uncertainties are connected  
with the sales risk of the order backlog, the completion of large-scale real    
estate development projects underway in Russia, and foreseeing and reacting to  
changes in the operating environment. In addition, the counterparty risk in the 
real estate development projects has increased, due to the financial crisis.    

The sales risk contained in the order backlog is mainly comprised of unsold     
residential units that are under construction. In Russia YIT made a decision    
after the review period to stop the construction in several residential projects
whose sales have not begun due to uncertainties in the economic situation. These
projects account for approximately EUR 320 million in the order backlog. The    
sales risk is managed by adjusting residential start-ups with sales trends. In  
Russia, sales of residential units mainly take place towards the end of the     
project, and the construction time is approximately two years. In Finland and   
the Baltic countries, the construction time is approximately one year. A more   
detailed account of the order backlog structure is presented above in the Order 
Backlog section.                                                                

In Russian real estate development projects, the risks are associated with the  
final costs of the technical solution of the water and drain connections for the
Gorelovo area. The negotiations regarding the water and drain connections are   
ongoing. The final costs resulting from the delay in the food plant being built 
in the area will be specified later, pursuant to the agreement made with the    
client.                                                                         

The consequences of the financial market crisis have been addressed by taking   
measures to strengthen cash flow and adjust cost structure to the market        
situation. YIT's business structure, in which cash flow-producing operations    
requiring little capital account for a significant part of the business,        
supports the Group's stability in uncertain market conditions.                  

In Russia, the financial market crisis has caused pressure on the external value
of the ruble. According to the financing policy, the Group's ruble exposure is  
hedged except for the equities of the subsidiaries in Russia, amounting to EUR  
159 million. Due to the high increase in the hedging costs, the policy was      
modified after the review period. The ruble forward contracts expiring during   
the last quarter are replaced by hedging against the ruble basket, up to the    
counter value of EUR 165 million. The devaluation of the ruble would cause a    
decrease in the equity of the subsidiaries in Russia, thus causing the          
equivalent change in the Group's equity, and, regarding the ruble basket        
hedging, an exchange rate loss the size of the devaluation in the income        
statement.                                                                      

The valuation of the currency forward contracts may increase the net financial  
expenses during the last quarter.                                               

YIT's risk management policy specifies the Group's most significant risks and   
methods of mitigating strategic and administrative risks. A more detailed       
account of YIT's risk management policy and the most significant risks has been 
published in the Annual Report for 2007, and of financial risks in the notes to 
the 2007 financial statements.                                                  

OUTLOOK FOR 2008                                                                

In January-September, operating profit increased in Building Systems and        
Industrial Services, and decreased in Construction Services Finland and         
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 and International         
Construction Services is estimated to decrease clearly during the last quarter  
compared to the previous year.                                                  

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.                                      

The estimate of profit development has been specified following the profit      
warning released on September 8, 2008. At that time, YIT estimated that the     
company's revenue will increase in 2008, but profit before taxes will decrease  
compared to the previous year. At the same time, YIT stated that the estimate on
profit development has weakened, because residential demand in Finland and      
construction volumes in the Baltic countries have decreased further.

ACCOUNTING PRINCIPLES OF THE INTERIM REPORT                                     

YIT Corporation's Interim Report for January 1 - September 30, 2008 has been    
drafted in line with IAS 34: Interim Financial Reporting. YIT has applied the   
same accounting policy and IFRS standards and interpretations in the drafting of
the Interim Report as in its annual financial statements for 2007. The          
information presented in the Interim Report has not been audited.               

Assessment of the future impact of new standards and interpretations            

In July 2008, IFRIC published a new interpretation guide IFRIC15: Agreements for
the Construction of Real Estate, the main effect of which on YIT Group will be  
on the income recognition procedures for development projects. The              
interpretation guide must be applied from 1 January 2009, assuming the European 
Commission has approved it by that date. The effects of the application of the  
interpretation guide on the financial data reported by the Group are being      
analyzed.                                                                       

FINANCIAL RISK MANAGEMENT

ACQUIRED BUSINESSES (EUR million)                                               

In the Building Systems segment, YIT acquired MCE AG's building system          
operations in Germany, Austria, Poland, the Czech Republic, Hungary and Romania 
on May 29, 2008. The transaction was finalised on August 1, 2008. The value of  
the transaction was EUR 55 million, following the deduction of contractual debts
and commitments the preliminary purchase price amounts to EUR 34.7 million.     
Expert fees amounting to EUR 1.5 million were included in the purchase price.   
The purchase price will be paid in cash. EUR 5.4 million of the purchase price  
was allocated to the customer base in the servicing business. The preliminary   
amount of goodwill is EUR 49.0 million. According to the management's           
assessment, the goodwill is based on the foothold in new markets provided by the
affiliated MCE group as well as opportunities of steering business towards      
long-term service agreements and servicing and maintenance operations. These    
measures contribute to improving the profitability of operations. In addition,  
synergy benefits are expected from the harmonisation of processes, extended     
range of services and procurement activities.                                   

The affiliated MCE group had an impact of EUR 58.6 million on YIT Group's       
revenue for the review period. The affiliated MCE group's revenue for the entire
period 1-9/2008 would have been EUR 263.3 million.                              

In addition, YIT Group made small corporate acquisitions. Building Systems      
boosted its competence as a provider of energy efficiency services by acquiring 
building automation specialist Computec Oy in Finland and made small corporate  
acquisitions and purchases of business operations in Finland, Norway and Sweden.

On May 29, 2008, YIT Construction Ltd signed an agreement on a corporate        
acquisition with which an 85 per cent share in the Czech company Euro           
Stavokonsult s.r.o. was acquired. The company was consolidated to YIT Group on  
July 1, 2008.                                                                   

The total acquisition price of all acquisitions made during the period totalled 
EUR 45.0 million.  Goodwill from minor acquisitions was allocated in full to    
intangible rights.
