YIT'S INTERIM REPORT: JANUARY 1 - SEPTEMBER 30, 2007:REVENUE AND OPERATING PROFIT GROWTH CONTINUED STRONGLY


YIT CORPORATION   CORPORATE RELEASE   INTERIM REPORT   OCT. 26, 2007 at 8:00    
											                                                                     
YIT'S INTERIM REPORT: JANUARY 1 - SEPTEMBER 30, 2007:                           
REVENUE AND OPERATING PROFIT GROWTH CONTINUED STRONGLY                          

The YIT Group's revenue and operating profit continued to rise in the           
January-September period of 2007. Revenue rose by 13 per cent and operating     
profit by 33 per cent compared with the previous year. The Group's order backlog
is strong.                                                                      

“Overall demand for our services has remained good in our whole business        
territory in the Nordic countries, Russia and the Baltic countries. The         
profitability of Construction Services was excellent. Housing demand improved in
Russia and the value of sales was bigger than in the previous year. In Finland, 
housing sales declined in the early autumn, but growth in other types of        
construction remained brisk. Building Systems forged ahead with improving       
profitability. In addition to a good earnings trend, the business segment's     
revenue is seeing substantial growth,” says Group CEO Hannu Leinonen.           

“All in all, the outlook is still favourable. Great need for housing in the     
large cities of Russia enables us to expand our residential production over the 
long term, too. The short-term outlook for housing demand in Finland has        
weakened, but residential construction is expected to remain at a solid level of
about 30,000 units per year. Construction of commercial and business premises is
growing in our entire business territory, which also increases demand for       
building equipment systems. Thanks to our strong order backlog and the          
prevailing market situation, we are well-poised to forge ahead with profitable  
growth in line with our plans,” adds Leinonen.                                  

Development by business segment                                                 

Building Systems' operating profit rose by 35 per cent to EUR 71.1 million      
(Jan.-Sept./2006: EUR 52.6 million). The operating profit margin increased to   
6.1 per cent (5.2%) of revenue. Revenue was up 16 per cent. The order backlog   
grew by 27 per cent.                                                            

Construction Services' operating profit increased by 24 per cent to EUR 150.0

Industrial and Network Services' operating profit amounted to EUR 18.9 million  
(EUR 12.8 million) and its operating profit margin to 5.3 (3.6%). Accounting for
the downscaling costs of Network Services, profitability remained at the        
previous year's level. Revenue rose by 2 per cent and order backlog by 23 per   
cent.                                                                           

Revenue up 13 per cent                                                          

The YIT Group's revenue for the January-September period grew by 13 per cent    
without major acquisitions and amounted to EUR 2,679.5 million (Jan-Sept/2006:  
EUR 2,376.3 million). Revenue in Russia increased by 23 per cent to EUR 203.4   
million (EUR 164.9 million). During the third quarter the revenue growth in     
Russia was 60 per cent (July-Sept/2007: EUR 89 million, July-Sept/2006: EUR 55  
million). Of YIT's revenue, 53 per cent came from Finland, 33 per cent from the 
other Nordic countries, 8 per cent from Russia and 6 per cent from the Baltic   
countries.

Operating profit grew by 33 per cent on the previous year and amounted to EUR   
229.1 million (EUR 172.4 million). The operating profit margin was 8.6 per cent 
(7.3%). Earnings per share were up 36 per cent to EUR 1.20 (EUR 0.88). Return on
investment for the 12-month period ending at the conclusion of the review period
was 25.8 per cent (25.2%).                                                      

Financial position remains stable                                               

The equity ratio was 33.8 per cent (34.6%). The balance sheet total at the end  
of the report period was EUR 2,418.4 million (EUR 1,925.5 million). Net debt    
rose to EUR 591.4 million (EUR 416.8 million). The gearing ratio was 79.1 per   
cent (68.1%). Net financial expenses amounted to EUR 22.0 million (EUR 14.3     
million), representing 0.8 per cent (0.6%) of revenue. Invested capital in      
Russia increased due to growth in business operations, the acquisition of plots 
and growth in ongoing production. At period's end, 30 per cent, or EUR 417      
million, of the Group's invested capital was tied up in Russia.                 

Order backlog growth 41 per cent                                                

The Group's uninvoiced backlog of orders is strong. It was 41 per cent higher at
the end of the period than a year earlier, having risen to EUR 3,172.5 million  
(EUR 2,246.2 million). The margin of the backlog is good.                       

Personnel strength rises                                                        

At the end of the period, the Group had 23,836 employees (22,188). Of YIT's     
employees, 49 per cent work in Finland, 36 per cent in the other Nordic         
countries, 8 per cent in Russia and 7 per cent in the Baltic countries.         

YIT estimates that it will start up 7,500 residences this year                  

YIT estimates that this year it will start up the construction of a total of    
about 7,500 residential units (start-ups in 2006: 7,404). Start-ups of          
market-financed residential units will amount to about 2,300 (2,818) in Finland,
about 4,500 (3,699) in Russia and about 700 (887) in the Baltic countries.      

Outlook for 2007                                                                

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

The outlook for revenue growth is supported by the strong order backlog, ongoing
economic growth 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.

traditional infrastructure maintenance and servicing business. In the review

million), representing 36 per cent (39%) of total revenue.

*) In the October-December/2006 period, Building Systems released provisions for
certain contractual obligations that had come to an end. This had a positive    
impact of EUR 7.2 million on operating profit.                                  

**) The operating profit of the Industrial and Network Services business segment
in January-March 2007 includes EUR 1.0 million and the operating profit for     
July-September 2006 EUR 5.1 million in costs related to the downscaling measures
carried out in the Network Services business unit in 2006.                      

Profit before taxes rose by 31 per cent to EUR 207.1 million (EUR 158.1         
million). Return on investment for the 12-month period ending at the conclusion 
of the review period was 25.8 per cent (25.2%). Earnings per share amounted to  
EUR 1.20 (EUR 0.88), up 36 per cent on the previous year.                       

YIT has set itself the target of increasing its operating profit to 9 per cent

The order backlog comprises the uninvoiced portion of orders and contracts from 
customers as well as residential and business premise development projects that 
involve a sales risk. In line with IFRS regulations, residential development    
projects are recognized as revenue using the formula degree of completion times 
the degree of sale. Business premise development projects are recognized as     
revenue using the formula degree of completion times degree of sale times the   
degree of lease. Contracts are typically recognized as revenue in line with the 
degree of completion.                                                           

The order backlog of Construction Services comprises contracts as well as       
residential and business premise development projects. Contracted projects are  
sold in full. Business premise development projects are sold to investors before
the start of the construction phase or in an early phase of the construction.   
The sales risk included in the order backlog is for the most part caused by     
unsold residences that are under construction. The sales risk is controlled by  
adjusting the number of residential start-ups in line with the trend in sales.  
Housing in Russia is sold mainly in the final stages of projects and the
construction time is about 2 years. 

About 60 per cent of the revenue of both Building Systems and Industrial and    
Network Services is generated by the maintenance and servicing business, which  
enjoys stable development. 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.                                                    

YIT CONFIRMS ITS STRATEGIC TARGETS                                              

On September 25, 2007, YIT Corporation's Board of Directors confirmed the       
Group's strategy and financial targets for the period 2008-2010. The financial  
target levels were confirmed unchanged. The targets are: average annual revenue 
growth of 10 per cent, operating profit of 9 per cent of revenue by 2009, return
on investment of 22 per cent, equity ratio of 35 per cent and a dividend payout 
ratio of 40-60 per cent of earnings after taxes and minority interest. In       
addition, YIT has set the target of increasing revenue in Russia by an average  
of 50 per cent annually during the 2006-2009 period.                    

Business operations will be bolstered in YIT's current business countries during
the next few years. The Building Systems business segment aims to increase its  
market share in its whole territory: the Nordic countries in particular, and    
also in the Baltic countries and Russia. In Construction Services, growth       
focuses on Russia and increasing business premise development projects.         
Residential development will be stepped up in Russia by strengthening YIT's     
presence in its current business cities and carrying on with expansion into     
other Russian cities with populations in excess of a million. The strategic     
focus of the Industrial and Network Services business segment is maintenance    
services outsourced by industry in Finland.                                     

In addition, the Group will seek to expand its geographical scope during the    
strategy period. Construction Services aims to start up residential development 
in central Eastern Europe. Building Systems is assessing opportunities for      
enlarging its offerings in Western Europe.                                      

A stock exchange release concerning the confirmation of the strategic targets   
was published on September 26, 2007.                                            

THE GROUP'S FINANCIAL POSITION REMAINS STABLE                                   

Invested capital in Russia increased due to growth in business operations, the  
acquisition of plots and growth in ongoing production. At period's end, 30 per  
cent, or EUR 417 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.         
Interest-bearing liabilities at the end of the period amounted to EUR 648.5     
million (EUR 451.1 million) and liquid assets to EUR 57.1 million (EUR 34.3     
million). Net debt rose to EUR 591.4 million (EUR 416.8 million). The gearing   
ratio was 79.1 per cent (68.1%) at period's end. The equity ratio was 33.8 per  
cent (34.6%). A total of EUR 82.6 million in dividends were paid during the     
report period (EUR 68.9 million).                                               

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.                                                                       

Financial income during the period amounted to EUR 1.8 million (EUR 2.3         
million), exchange rate losses to EUR 1.2 million (EUR 1.8 million) and         
financial expenses to EUR 22.6 million (EUR 14.8 million). Net financial        
expenses were EUR 22.0 million (EUR 14.3 million), or 0.8 per cent (0.6%) of    
revenue.                                                                        

Short-term credit was converted into long-term credit by means of two EUR 50    
million private placement bonds in March.                                       

The proportion of fixed-interest loans in the Group's entire loan portfolio was 
66 per cent (36%). Loans raised directly on the capital and money markets       
amounted to 58 per cent (49%).                                                  

The construction-stage contract receivables sold to financing companies totalled
EUR 250.4 million (EUR 225.4 million) at the end of the period. Of this amount, 
EUR 104.8 million (EUR 115.8 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 8.0 million (EUR 7.0 million), is included in financial expenses 
in its entirety.                                                                

Participations in the housing corporation loans of unsold completed residences, 
EUR 36.7 million (EUR 22.7 million), are also included in interest-bearing      
liabilities, but the interest on them, EUR 1.2 million (EUR 0.5 million), is    
booked in project expenses, as said interest is included in housing corporation 
maintenance charges.                                                            

Interest-bearing liabilities included EUR 1.9 million in leasing commitments    
(EUR 3.3 million).                                                              

The balance sheet total at the end of the report period was EUR 2,418.4 million 
(EUR 1,925.5 million).                                                          

CAPITAL EXPENDITURES AND ACQUISITIONS                                           

Gross capital expenditures on non-current assets included in the balance sheet

period, representing 1.3 per cent (1.3%) of revenue. Investments in construction

MAJOR NEAR-TERM BUSINESS RISKS AND UNCERTAINTIES

announced on September 28, 2007 that its holding in YIT's shares had declined   
below 5 per cent.                                                               

OUTLOOK FOR THE ECONOMY REMAINS GOOD, BUT UNCERTAINTY INCREASES                 

Bank of Finland states in its economic forecast that the outlook for the global 
economy is still good, but the risk of slow down has increased. In YIT's        
territory, the boom in the Nordic countries peaked last year, but according to  
Nordea's estimate in September the economic growth will continue during the next
few years, outpacing growth in 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 Russian, Estonian, Latvian and Lithuanian economies is slackening        
slightly but is still over twice as fast as in the Nordic countries. According  
to Nordea rapid inflation threatens to put a halt to positive economic          
development in Latvia and Estonia in particular. Expectations of a rise in euro 
interest rates have declined and the markets anticipate that the main lending   
rate of the European Central Bank will be at its present level next summer.     
Great need for housing in the large cities of Russia enables the company to     
expand residential production over the long term, too. Euroconstruct estimates  
that the growth in the construction of business premises compensates the decline
in housing production in the Nordic countries during next year. Growth in       
exports and industrial output increases the need for industrial investments and 
maintenance in all the Nordic countries.                                        

Finland                                                                         

In October, the Bank of Finland estimated that GDP will rise by 4.4 per cent    
this year and 3.1 per cent the next. The improvement in the employment count,   
the positive trend in incomes and the still moderate interest rate level support
household consumption and demand for housing. Growth in the index of wage and   
salary earnings will rise to 3.5 per cent this year and to 5.0 per cent the     
next. Private investments will grow by 5.7 per cent, with growth next year      
amounting to 5.4 per cent.  According to the estimate released by the Ministry  
of Finance's expert group on construction in August, building construction will 
see growth of 5-6 per cent this year and 3 per cent the next. The business cycle
report published by the Confederation of Finnish Construction Industries RT in  
October states that 32,000 residential units will be started up this year and   
31,000 the next, while the number of start-ups was 34,000 last year. In June,   
Euroconstruct estimated that residential construction will decline by 2.4 per   
cent this year, while other types of building construction will see growth of   
13.1 per cent. Euroconstruct predicts a decline of 0.9 per cent and 0.5 per cent
during the subsequent two years, with production volumes remaining high in      
relation to the resources available. Civil engineering will grow slightly in    
2007 - 2009. According to the business cycle bulletin that was released by the  
Finnish Association of Building Owners and Construction Clients RAKLI in        
September, the construction of offices and business premises will remain brisk  
in the Greater Helsinki Area, but the number of start-ups will not see further  
growth. According to VTT, 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 investment survey the Confederation of Finnish Industries EK  
released in June indicates that the value of the fixed investments of industrial
companies will grow to almost EUR 3.9 billion this year, representing an        
increase of slightly over eight per cent on the previous year. The market for   
industrial, property and infrastructure maintenance will expand as the          
outsourcing trend progresses.                                                   

Sweden                                                                          

In August, the Swedish National Institute of Economic Research KI estimated that
Sweden's GDP will grow by 3.5 per cent this year, 3.8 per cent in 2008 and 3.1  
per cent in 2009. The factors underlying the positive development of the economy
are the high capacity utilization ratio in industry, solid earnings, and the    
positive incomes trend enjoyed by households. Time wages will increase by 4.3,  
4.7 and 4.8 per cent in 2007 - 2009. The ranks of the employed will swell by a  
total of 100,000 people this year and further by a total of 100,000 during the  
subsequent two years. The unemployment rate will decline from the present year's
figure of 6.2 per cent to 5.5 per cent in 2009. Inflation will accelerate to    
over 2.5 per cent. KI expects that the Riksbank, Sweden's central bank, will    
keep raising its policy rate, nudging it to 4.75 per cent next year. The growth 
of the national economy rests on a broad footing. In 2007, exports will increase
by 5.8 per cent and next year by 7.1 per cent due to international demand and   
the effect of the relatively weak Swedish kronor. Fixed investments will see    
growth of 9.6 per cent this year, but growth will slacken to 5.6 per cent next  
year. Fixed investments by industry will increase by 12.5 per cent this year and
by 4.5 per cent the next. Investments by the service sector are higher than     
those of industry, with growth amounting to 7.5 per cent this year and to 6.9   
per cent the next. According to the construction business cycle barometer KI    
released in September, order backlogs have grown, construction activity and     
employment have increased, and companies expect to see further production       
growth. Over 70 per cent of construction companies reported that the shortage of
skilled labour slows down production growth, and a third expect tender prices to
rise. In October, the Swedish Construction Federation BI predicted that         
residential investments will grow by 13 per cent this year and by 4 per cent the
next. Production of other types of buildings will see growth of 8 per cent this 
year and 6 per cent in 2008. The elimination of state subsidies from the        
beginning of the present year and changes in housing taxation artificially      
inflated housing start-ups to 42,100 units last year. The Swedish Construction  
Federation BI estimates that housing start-ups will be 29,000 during this year  
and 37,000 during the next. The labour shortage has been alleviated with foreign
labour and a vigorous drive to develop productivity.                            

Norway                                                                          

Norway's four-year boom is levelling off, with growth settling at a more        
moderate level. According to the forecast released by Statistics Norway at the  
beginning of September, GDP will grow by 3.5 per cent this year and by 3.7, 2.2 
and 2.7 per cent during the next three years. The GDP growth figures for        
continental Norway are 5.1 and 3.1 per cent, respectively. Household consumption
will grow by 6.3 per cent this year and by 3.7 per cent the next. Fixed         
investments will grow by 7.8 per cent this year and by 6.6 per cent the next.   
Investments in housing will grow by 6.8 per cent this year and by 3.1, 0.5 and  
-2.3 per cent in 2008-2010. Fixed investments by business and industry will rise
by 8.9 per cent this year and by 8.2, 3.4 and 3.3 per cent during the next three
years. Investments by the oil and gas sector will gain momentum again as from   
the beginning of next year, with annual growth of over 9 per cent. Housing      
prices will rise by about 13 per cent this year, as they did last year, but it  
is expected that the increase next year will only be 4.5 per cent.  Prices in   
Bergen and Trondheim declined in September. The construction of 33,300          
residential units was started up last year. Start-ups in the January-August     
period numbered 20,700 units, an increase of 4.1 per cent on the corresponding  
period of the previous year. The floor area of the residential units that were  
started up was 7.1 per cent larger than last year, while in the case of other   
buildings the increase in floor area was 18.7 per cent. Norges Bank raised its  
key interest rate (“sight deposit rate”) to 4.75 per cent in August. Statistics 
Norway expects that the key interest rate will rise to 5.25 per cent in the next
few months and remain there until 2010. Higher interest rates, stronger currency
and a labour shortage slow down growth in many sectors of the economy.          
Statistics Norway nevertheless expects economic development to remain positive  
until at least 2010 and the unemployment rate to drop to 2.4 per cent.          

Denmark                                                                         

In September, Nordea anticipated that GDP growth will amount to 1.9 per cent    
this year. Growth will slacken to 1.4 per cent in 2008. Export growth gathered  
steam last year, and will continue at an annual rate of slightly over 4.5 per   
cent in 2007-2009. Growth in private consumption is estimated to slacken to 1.8 
per cent this year. Investments will increase by 3.5 per cent during the present
year. Housing prices rose by 24.3 per cent last year. The rapid rise in prices  
has increased the supply of housing, as a result of which the increase in       
housing prices is expected to come to a halt. Prices have declined in           
Copenhagen. In June, Euroconstruct estimated that the number of new residential 
start-ups will be about 29,000 each year from 2007-2009, compared to 31,000 last
year. Growth in real incomes and full employment have strengthened the          
confidence of households in their own finances, which means that opportunities  
in the demand for housing will remain good. Housing renovation will not see     
growth in 2007-2009. According to Euroconstruct, the construction of other types
of new buildings will increase by 4.7 per cent this year, and by 5.6 and 5.0 per
cent in 2008 and 2009, with renovation works on such buildings rising by 2 per  
cent annually. Construction will remain buoyant during the next few years -     
maintaining it at a high level will entail greater use of labour from the new EU
countries and Germany.                                                          

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 in June, the  
aggregate GDP of the Baltic countries amounted to EUR 53 billion and the value  
of construction to EUR 7.2 billion in 2006. In September, Nordea predicted that 
Latvia's GDP will grow by 10.0 per cent this year and by 8.0 per cent in 2008.  
GDP growth in Estonia would be 7.7 and 6.4 per cent, respectively, and in       
Lithuania 7.8 and 8.3 per cent. Inflation in Estonia is double the EMU average, 
and it is triple in Latvia. Growth in investments this year will be 14 per cent 
in Estonia, 16 per cent in Latvia and 17 per cent in Lithuania. In 2008,        
investments will continue to grow at a rate of 12-13 per cent in these          
countries, and by 19 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  
22,000 residential units will be completed in the Baltic countries this year.   
Building permits have been granted for twice as many residences as have been    
completed. According to the estimates collected by VTT, 30 per cent more        
residences and other buildings were completed in Estonia last year than in 2005.
The number of residences completed in Latvia grew by 50 per cent and the        
capacity of other types of buildings by 40 per cent. Residences and other       
buildings completed in Lithuania saw growth of 20 per cent. The value of the    
mortgage stock in Estonia has risen to 33 per cent relative to the value of GDP,
which is on a par with Finland. The same figure is 29 per cent in Latvia and    
only 13 per cent in Lithuania. In Estonia the rapidly increased apartment prices
and rise of interest rates have diminished the demand for mortgages during the  
first part of the year, which has been reflected negatively in the housing      
market. Housing prices have declined in Estonia and Latvia during 2007.         

Russia                                                                          

The high price of oil supports Russian economic growth. In September, Nordea    
estimated that Russia's GDP will grow by 7.5 per cent this year and by 6.9 per  
cent in 2008. 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 8.3 per cent this year and 
7.7 per cent the next. The rate of growth in investments will accelerate to 20  
per cent this year and continue at the same rate the next. The bulk of the      
investments are earmarked for raw material-intensive production and the         
transport infrastructure. The share of investments accounted for by construction
is also on the rise, but the share of industry has declined. Investments have   
gained momentum from private sector borrowing and record-high direct foreign    
investments. The pace of investments will still remain 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       
employment and incomes trend, household consumption has become the primary      
engine of growth. Private consumption will rise by 12 per cent this year,       
comprising half of GDP. The greater affluence of the middle class has           
strengthened demand for market-financed residences in large Russian cities. 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, weakening home purchasing ability.
The rate of growth in housing prices has remained moderate in 2007.             

DEVELOPMENT BY BUSINESS SEGMENT                                                 

BUILDING SYSTEMS                                                                

Building Systems continued to improve its profitability and focused on revenue  
growth. The business segment's revenue in the January-September period was up 16
per cent to EUR 1,170.3 million (Jan-Sept/2006: EUR 1,009.2 million). The share 
of the business segment's revenue accounted for by the maintenance and servicing
business was 63 per cent (65%). Business operations have been strengthened in   
line with the strategy in Sweden and Norway with six small acquisitions during  
2007.                                                                           

Operating profit grew by 35 per cent to EUR 71.1 million (EUR 52.6 million). The
operating profit margin improved to 6.1 per cent (5.2%). The operating profit   
margin in Q3 2007 was 6.8 per cent (6.3%).                                      

The order backlog at the end of the period was up by 27 per cent to EUR 740.5   
million (EUR 582.7 million).                                                    

The business segment had 12,513 employees (11,456) at the end of the period.

Market situation in Sweden remained favourable                                  

The trend in the market for building system services continued to be favourable.
New construction remained brisk, with growth in the construction of commercial  
and business premises in particular. Repair and maintenance works increased.    
Industrial output continued to grow.                                            

During the report period, an agreement was made with AstraZeneca for the        
implementation of all the piping and electrical installation works of a new     
laboratory that will be built in Gothenburg. Full turbine and water treatment   
piping will be supplied to Övik Energi AB for a new thermal power plant.        

A six-year service agreement was signed with Wedholms Industrihus AB, covering  
the upkeep of ventilation systems and the modernization of building equipment   
systems.                                                                        

Market growth in Norway                                                         

The market for building system services saw growth compared with the previous   
year. New construction increased, especially in the case of commercial and      
business premises. Demand for renovation remained good.                         

In Oslo, YIT is responsible for electrical installation works at the Akerselva  
Atrium centre built by NCC, which features both a shopping centre and office    
space. In Halden, electrical works will be carried out at a state-of-the-art    
penitentiary built by Statsbygg, the Directorate of Public Construction and     
Property.                                                                       

Maintenance and servicing agreements under the ServiFlex concept have been made 
with many partners. The portfolio of services offered to both public agencies   
and airlines has been steadily expanded at Oslo Airport Gardermoen.             

Good market situation in Finland                                                

The market for building system services remained good. The market for property  
services and property management services continued to grow. Structural changes 
in industry and reforms in municipal service structures open up the market to   
the outsourcing of technical services and partnership agreements.               

Service agreements for property management were made with the international     
property investors Property Group and Reef. The cooperation agreement made with 
Tapiola Real Estate Ltd was expanded to cover the premises management and upkeep
of Business Park Mankkaa, which will be completed in Espoo. The provision of    
acute maintenance services for housing corporations and real-estate companies   
was expanded to new localities. An agreement on the implementation of industrial
energy analyses was made with Huhtamäki Oyj and the baking company Elonen Oy    
Leipomo.                                                                        

Construction remained brisk in Denmark                                          

The economy continued to develop well and construction remained brisk. Demand   
for building system services held firm in both industry and the construction of 
commercial facilities and public premises. Corporate interest in the outsourcing
of technical services increased.                                                

A long-term service agreement was made with Mærsk Olie og Gas for the           
maintenance of the electrical systems and instrumentation of oil rigs on the    
North Sea. A property management agreement was forged with Merrild Kaffe in     
Kolding; the agreement will be in effect until further notice. An order for a   
new ventilation system came in from Danske Bank under a long-term service       
agreement.                                                                      

Electrical installations will be supplied for the University of Copenhagen as   
part of the reorganization of its campus area. Reconditioning of office         
ventilation systems will be carried out for Novo Nordisk. YIT will perform      
electrical works at a new kindergarten for the municipality of Vejle.           

Good market situation holds in Estonia, Latvia, Lithuania and Russia            

The market for building system services remained favourable in Russia.          
Construction activity was brisk and western investments saw further growth.     
Demand for property maintenance and property management services grew in Russia 
and the Baltic countries.                                                       

A two-year agreement on property management and technical maintenance services  
was signed with K-Rauta in Russia. An electrical contracting agreement was made 
with Knauf Hips Novomoskovsk Ltd in the Tula area. Building equipment works at  
the Kolomagi residential complex built by YIT were agreed on in St Petersburg.  

In Lithuania, property management and technical maintenance agreements covering 
two sites were signed with Baltic Red Management UAB. In the City of Elektrenai,
an agreement was forged for a total technical solution for the Maxima XX        
supermarket to be carried out as a Design & Build delivery. Numerous electrical 
contracts got under way in Estonia at business premises and warehouses on behalf
of Elion Ettevötted, Skanska and Eesti Ehitus.                                  

CONSTRUCTION SERVICES                                                           

In the January-September period, the revenue of Construction Services grew by 13
per cent on the previous year and amounted to EUR 1,196.1 million (EUR 1,055.9  
million). The share of revenue accounted for by the maintenance business was 3  
per cent (3%). Of the revenue, 71 per cent came from Finland, 16 per cent from  
Russia, 13 per cent from Lithuania, Latvia and Estonia and less than one per    
cent from other countries.                                                      

Operating profit was up 24 per cent to EUR 150.0 million (EUR 120.8 million).   
The operating profit margin remained excellent, 12.5 per cent (11.4%).          

The order backlog grew by 48 per cent to EUR 2,263.3 million (EUR 1,524.4       
million).                                                                       

The business segment had 6,394 employees (5,511) at the end of the period.      

Housing sales started to grow in Russia                                         

Both the need for and interest in new housing have remained strong in Russia.   
The number of residences sold by YIT in the January-September period was lower  
than in the previous year, but housing sales turned to growth at the end  
of the review period. In Q3 2007, YIT sold 476 residential units in Russia      
(July-Sept/06: 462).                                                            

In 2006, the prices of residences in some large cities in Russia saw an         
exceptional rise of 60-100 per cent due to the decline in supply, weakening home
purchasing ability in the first part of 2007. The rate of growth in housing     
prices has remained moderate in 2007.                                           

In Russia, YIT builds housing in St Petersburg, Moscow, the Moscow Oblast,      
Yaroslavl, Yekaterinburg and Kazan. In June, YIT expanded its operations in line
with its strategy to Rostov-na-Donu in Russia by setting up a joint venture in  
the city. The aim is to start up construction on the first site by the end of   
2007.                                                                           

Of the Baltic countries, housing demand remained moderate in Lithuania. In      
Estonia and Latvia the demand is weak and the prices of residences have         
declined.                                                                       

In July-September, the average selling price of the residences YIT built in     
Russia was about 53 per cent (July-September/06: 40%) of the average selling    
price of the market-financed residences sold by YIT in Finland, and in the      
Baltic countries about 59 per cent (60%).                                       

Housing sales in Finland declined slightly                                      

In January-September 2007, YIT sold 1,935 residential units in Finland          
(Jan-Sept/06: 2,057). There was growth in the number of residences sold to      
rental housing companies, while the number of residences sold directly to       
consumers decreased.                                                            

Leisure-time residences were sold at Ylläs in Kolari, Vuokatti in Sotkamo, Tahko
in Nilsiä and Virpiniemi in Haukipudas. Construction of leisure-time residences 
and centres proceeded as planned. New cooperation agreements were signed for    
projects at the Hiekkäsärkät sand dunes in Kalajoki. 

YIT cooperates with numerous cities in the development of commercial and tourism
services and the supply of residences. Projects are ongoing and under planning  
in cities such as Rovaniemi, Kemi and Loviisa.                                  

YIT estimates that it will start up 7,500 residences this year                  

YIT estimates that this year it will start up the construction of a total of    
about 7,500 residential units (start-ups in 2006: 7,404). Start-ups of          
market-financed residential units will amount to about 2,300 (2,818) in Finland,
about 4,500 (3,699) in Russia and about 700 (887) in the Baltic countries. The  
number of residential start-ups in Finland has been reduced due to the          
slackening of the housing sales in the early autumn.                            

The market outlook for developer-contracting of housing is expected to remain   
good on the whole in YIT's market area. Growth in housing demand in Finland has 
come to a halt after rising for many years. However, the Ministry of Finance    
forecasts that annual construction of housing will remain at a level of about   
30,000 units. Housing demand is maintained by the improvement in the employment 
count, the development of incomes and wealth, the brisk ongoing population shift
and the still moderate interest rates. In Russia and the Baltic countries,      
strong economic growth, the positive trend in household earnings and the need to
improve housing quality uphold the demand for residences.                       

At the end of September, YIT had 299 completed unsold residential units in      
Finland; the corresponding figure at the end of June was 291. At the end of     
September, there were 13 completed unsold apartments in Russia and 2 in the     
Baltic countries.

The recording of the status of residential units in Russia has changed.         
Apartments are deemed to have been completed three months after the authorities 
have performed the inauguration inspection. Previously an apartment was         
designated as being completed only when the homebuyer had registered it with the
authorities. The figures for residences under construction, completed, and      
completed and unsold in the January-September/2007 and January-September/2006   
periods have been presented in line with the new practice. In Russia and Baltic 
countries there may be small changes in the number of apartments during the     
construction period due to splitting up or combining the apartments.            

Market-financed residential development projects sold to investors have been    
added to residential units sold in Finland.

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.                                                               

Construction of commercial and business premises remains brisk                  

Construction of office, retail and logistics premises was brisk in Finland and  
the outlook remained favourable. Demand for offices stayed good in the Greater  
Helsinki Area. Construction of business premises is also brisk in Russia and the
Baltic countries.                                                               

YIT has started up and sold numerous property development projects in 2007:     
Grandis Retail Centre in Vantaa, the Entresse Shopping Centre in Espoo,         
Kauppakortteli Atomi shopping quarter in Riihimäki as well as YIT's head office 
and the Duetto Business Park in Helsinki. In September, YIT sold the Joensuu    
Shopping Center project, which was developed by the company and is currently    
under construction, to the Danish real-estate investment company I/S            
EjendomsInvest.                                                                 

In July-September, YIT started up the construction of the AviaLine 1 office     
building in Vantaa. A lease agreement was forged with the head tenant of the    
Koskelo Trade Park in Espoo and the Viinikkala Logistics Centre in Vantaa;      
construction work on these projects continued.                                  

Construction of offices and logistics facilities that will be owned by EPI      
Russia and a production plant for Atria continued in St Petersburg, Russia. In  
Lithuania, the last phase of the FEZ logistics project was completed in Kaunas, 
as was the extension of the Parliament Building in Vilnius.                     

Demand holds firm in infrastructure construction                                

The market for civil engineering remained good. Reforms in municipal service    
structures open up the market to the outsourcing of technical services and      
partnership agreements. During the report period, three- and four-year area     
maintenance agreements were signed with the Cities of Lahti and Oulu.           

A large-scale contract came in from the Lapland Road Region of the Finnish Road 
Administration for the construction of two bridges on Highway 4 in Kemi. An     
agreement was made with the City of Espoo for the construction of               
Lintulaaksontie road. The construction of a fitness centre for Meilahden        
Liikuntakeskus Oy was agreed in Helsinki. YIT landed an order from Fortum Lämpö 
Oy for the construction of a boiler facility in Seinäjoki.                      

INDUSTRIAL AND NETWORK SERVICES                                                 

The revenue of Industrial and Network Services grew by 2 per cent in            
January-September and amounted to EUR 359.0 million (EUR 352.9 million). The    
share of revenue accounted for by the maintenance business was 58 per cent      
(60%). Of the revenue, 91 per cent came from Finland and 9 per cent from other  
countries.                                                                      

Operating profit was EUR 18.9 million (EUR 12.8 million). The operating profit  
margin was 5.3 per cent (3.6%). Accounting for the downscaling costs of Network 
Services, profitability remained at the previous year's level. Q1/2007 operating
profit includes EUR 1.0 million and the operating profit for Q3/2006 EUR 5.1    
million in costs related to downscaling measures carried out in the Network     
Services business unit.                                                         

The order backlog at the end of the period was up 23 per cent to EUR 221.7      
million (EUR 180.3 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 4,593 employees (4,895).     

Demand for services for industry remains brisk                                  

The market situation for maintenance services for industry remained good. During
the report period, end-to-end maintenance works and large-scale maintenance     
shutdowns were carried out. Maintenance services were provided for the forest   
industry at StoraEnso's mills in Imatra, UPM's Seikku mill in Pori and Botnia's 
mill in Kemi. maintenance shutdowns were carried out for the energy and process 
industry at Neste Oil's oil refinery and Borealis' ethylene and phenol plant in 
Porvoo, Ovako Bari's steel plant in Imatra and Pohjolan Voima's power plant in  
Meripori.                                                                       

New orders for investment projects for industry                                 

Demand remained solid in investment services for industry and many new orders   
came in during the report period. Agreements were made with Siemens Plc for a   
turnkey delivery of piping for a combined cycle gas power plant in Marchwood,   
England, and Metso Power Oy for the delivery of piping for a soda recovery and  
power boiler plant in Brazil. Deliveries of high-pressure piping for Porin      
Prosessivoima's power plant as well as tank and piping for the Talvivaara mine  
project in Sotkamo were agreed in Finland. An agreement was signed with         
StoraEnso for an electrical contract in Varkaus. The implementation of          
lightweight substations in Hämeenlinna was agreed with Vattenfall.              

During the report period, piping deliveries as well as electricity distribution 
and instrumentation works for UPM's REC08 project in Kuusankoski and piping     
deliveries for the VALKI project in Valkeakoski were under way. In Tornio, YIT  
has been responsible for a gasometer delivery for Outokumpu.                    

Market for network services is still tight                                      

The market situation in field services for teleoperators continued to be tight. 
Mobile network construction grew towards the end of the period. The market for  
electricity network upkeep, repair and construction remained solid.             

During the report period, YIT made two Finland-wide agreements with Elisa, under
which YIT is responsible for the construction of 3G base station equipment for  
mobile phone networks as well as the installation and repair of DSL connections 
and related devices for corporate networks.                                     

EVENTS AFTER THE END OF THE REVIEW PERIOD                                       

On October 1, 2007, YIT Industrial and Network Services Oy acquired Inesco Oy,  
which specializes in projects to upgrade performance in energy and material     
consumption in industry.                                                        

On October 2, 2007, YIT Construction Ltd and its Lithuanian subsidiary AB YIT   
Kausta signed an agreement on the sale of their shares in UAB Kausta Guder,     
which engages in the lease, sale and servicing of small construction machines in
Lithuania and Latvia. The approval of the Lithuanian competition authority is   
required for the consummation of the transaction.                               

In the Building Systems business segment, YIT A/S acquired Monies & Andersens   
Eftf. A/S in Denmark on October 12, 2007. The acquiree provides building        
equipment contracting, installation and maintenance services in the Copenhagen  
area. As a result of the transaction, 40 people will transfer to YIT's employ on
January 1, 2008.                                                                

OUTLOOK FOR 2007                                                                

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

The outlook for revenue growth is supported by the strong order backlog, ongoing
economic growth 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.

Management of the interest rate risk of interest-bearing liabilities            

Derivative interest-rate contracts to which hedge accounting is applied are     
designated as hedges of floating rate loans: 3 month Euribor-linked loan with a 
nominal value of EUR 225 million and 6 month Euribor-linked loan with a nominal 
value of EUR 45 million. These hedges qualify for effective hedging requirements
and changes in fair value are, in accordance with the accounting principles     
applied in the financial statements, recognized in the fair value reserve in    
shareholders' equity. Derivative interest-rate contracts to which hedge         
accounting is not applied are designated as hedges of floating rate 1-3 month   
Euribor-linked loans with a nominal value of EUR 130 million. Fair value changes
in such derivative interest-rate contracts are recognized through profit or loss
in accordance with the accounting principles applied in the financial           
statements. Derivative interest-rate contracts decrease the weighted average    
rate of the whole loan portfolio by 0.451 percentage point.                     

The duration of long term loans and derivative instruments hedging these loans  
was 1.27 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 on September
30, 2007 have affected the annual net financial expenses by EUR 3.0 million (EUR
4.1 million on Dec 31, 2006).
