OLE JOHANSSON, PRESIDENT & CEO:"Good demand continued in the markets boosting new orders and
resulting in yet another all-time high order book of EUR 5.5 billion.
Slight decline in net sales during the second quarter is due to the
timing of the power plant deliveries. The Services grew strongly at
23%. Profitability developed as expected. The enlarged manufacturing
capacity in Vaasa, Trieste and China will support continuing growth
prospects."

WÄRTSILÄ'S PROSPECTS IN 2007
Demand in the ship power and energy markets looks likely to remain
active for Wärtsilä for the next two quarters. Based on the strong
order book, Wärtsilä's net sales are expected to grow this year by
around 15%. Profitability will exceed 9%. Wärtsilä's profitability
varies considerably between the quarters as will also be the case
this year. Wärtsilä sees further possibilities for growth in 2008.

MARKET DEVELOPMENT

Ship Power
The shipbuilding market during the first half of 2007 was very active
despite a somewhat slow start at the beginning of the year. Measured
in number of vessels  contracting was above the level of the
corresponding period last year with 1,676 (1,566) vessels registered.
Measured in deadweight tons, the order level was also higher than in
the same period last year especially due to the very high volume of
dry bulk vessels ordered.

The shift in focus from smaller to larger vessels and revitalization
of the container vessel market have evened out the differences
between the  geographical shipbuilding markets. China remains the
biggest beneficiary having a share of 42% in the number of vessels
ordered. Korea has closed the gap from the beginning of the year,
raising its share to 33%. Europe received 8% and Japan 9% of the new
orders.

Wärtsilä's market shares in Ship Power
The total market volume for medium-speed main engines for the last 12
months at the end of the second quarter 2007 was 9,400 MW. Wärtsilä's
share fell slightly from a very high level to 42% (46% at the end of
the previous quarter). The change in the order mix from big engines
to smaller ones was the main factor behind this development. The
low-speed main engine market grew to 29,400 MW (27,700). Wärtsilä's
market share in this market was 15% (14% at the end of the previous
quarter). In auxiliary engines Wärtsilä's market share was 5% (6% at
the end of the first quarter of 2007).

Power Plants
Demand in the Power Plant market remained high and all segments
relevant to Wärtsilä - baseload production, industrial
self-generation and grid stability - were active during the review
period. Markets continued to be globally active.

Demand for oil-fired power plants was strong during the review
period, especially in Africa and the Middle East. The order intake
for power plants running on renewable fuels, which includes among
others liquid bio-fuel power plants, continued actively especially in
Italy. Demand for gas-fired power plants, remained at a good level.

Wärtsilä's market shares in Power Plants
Wärtsilä has a strong foothold in the market for heavy fuel oil (HFO)
power plants and holds approximately a third of the market in
Wärtsilä's power range. In the market for light fuel oil (LFO) power
plants, including liquid biofuels, Wärtsilä has approximately a
quarter of the market. The gas power plant market is a growing market
where Wärtsilä sees good growth potential. Wärtsilä's current market
share in gas power plants is approximately 8% of the relevant market.

ORDER INTAKE AND ORDER BOOK
Wärtsilä's order intake continued strong showing growth of 15% in the
second quarter and amounted to EUR 1,369 million (1,190). In the Ship
Power business the April-June period marked an all time high quarter
with the order intake amounting to EUR 673 million (660). The Power
Plants order intake for the second quarter amounted to EUR 326
million (243) representing growth of 34%.

In the review period January-June Wärtsilä's order intake totalled
EUR 2,526 million (2,214), representing growth of 14%. The Ship Power
order intake grew further by 3% from the high level in the
corresponding period last year (1,161) and was EUR 1,194 million.
 Offshore vessels and platforms continued to dominate the new orders.
One of the landmarks was a contract to supply an entire power,
automation and propulsion system for a well-testing FPSO vessel for
Brasilian Dynamic Producer Inc. In the cruise ship segment Wärtsilä
received an order for the second vessel in the project Genesis for
Caribbean Cruise Ltd. Delivery will consist of the main engines and
transverse tunnel thrusters.

The Power Plants order intake for the review period was 41% higher
than during the corresponding period last year and totalled EUR 537
million (381). The largest oil-fired power plant orders were received
from Pakistan, Senegal and Aruba. Success in the liquid bio-fuel
power plants continued during the second quarter and Wärtsilä
received three orders with a total output of 114 MW in Italy. The
largest gas power plant orders were received from Russia and
Bangladesh.

At the end of the review period Wärtsilä's order book stood at an
all-time high of EUR 5,460 million (3,772), representing growth of
45%. Some 30% of Wärtsilä's total order book is due for delivery in
2007. The Ship Power order book was EUR 3,681 million (2,505),
corresponding deliveries for approximately two years. The Power
Plants order book stood at EUR 1,361 million (887), roughly half of
which is due for delivery in 2007.

STRATEGIC ACQUISITIONS AND JOINT VENTURES
In January Wärtsilä and Hyundai Heavy Industries Co. Ltd (HHI) signed
an agreement to set up a 50/50-owned joint venture in Korea to
manufacture dual-fuel engines for LNG (liquefied natural gas)
carriers. The total equity of the company will be EUR 58 million,
Wärtsilä's share being EUR 29 million. The joint venture will
manufacture Wärtsilä 50DF dual-fuel engines for the Korean, Japanese,
Chinese and Taiwanese shipbuilding markets. The first engine will be
delivered in the second half of 2008. The Trieste delivery center in
Italy will continue to manufacture Wärtsilä 50DF dual-fuel engines
for the marine markets outside East Asia and for the growing
worldwide power plant market. In June the European Union competition
authorities cleared the joint venture and the permits from different
authorities have been received to start the business.

In February Wärtsilä acquired the Swedish company Senitec AB. The
company is specialized in environmental technology products for
separating waste such as oily water and sludge in power plants,
harbours and ships. This new business gives Wärtsilä the possibility
to expand its offering of environmental solutions in waste
management.

In February Wärtsilä acquired the entire business of Marine Propeller
(Pty) Ltd in Cape Town, South Africa. Marine Propeller (Pty) Ltd
focuses mainly on repairing propellers.

In May Wärtsilä continued extending its service offering in
Propulsion services with the acquisition of UK-based propeller repair
company McCall Propellers Ltd. The acquisitions complement Wärtsilä's
propeller services.

The total acquisition price of the acquisitions mentioned above is
EUR 25 million out of which EUR 17 million is reported as goodwill.

In May Wärtsilä signed an agreement to acquire the marine business of
Railko Ltd. in the UK, a company specializing in stern tube bearing
technology. The acquisition will improve Wärtsilä's competitive
position in oil-lubricated bearing systems and adds water-lubricated
bearings to the product portfolio. Railko's products are used on all
types of vessels, from cruise ships to cargo vessels. The acquisition
was closed at the beginning of July.

OTHER STRATEGIC ISSUES
In January Wärtsilä announced a public offer to the minority
shareholders of Wärtsilä India Ltd to acquire 1,240,599 shares, or
10.3% of the share capital. The offer period expired on 23 March
2007. The delisting offer was successful and pursuant to the offer
7.3% of the total shares were acquired. This implies a consideration
of EUR 10 million, of which EUR 7 million was recognised as goodwill.
Wärtsilä Corporation holds directly or indirectly 97.0% of Wärtsilä
India shares. The shares of Wärtsilä India Ltd were delisted from the
Bombay Stock Exchange on 18 June 2007.

To improve marine customer service in the rapidly growing Chinese
markets Wärtsilä opened a large reconditioning workshop in Shanghai
in March. In May Wärtsilä also opened a service workshop close to
Saigon port in Ho Chi Minh City and an office in Hanoi to serve the
growing Vietnamese shipping, shipbuilding and power industries.

The demand for training services is steadily rising and Wärtsilä
opened a new training centre in Korea to provide customer training in
the world's largest shipbuilding country.

MANUFACTURING
The investment programmes for enlarged production capacity of
medium-speed engines in Vaasa and Trieste to meet the growing market
demand are proceeding. The full capacity increase will be in use
during the second half of 2007 as planned. Wärtsilä's worldwide
supplier network has continued to build up capacity and most of these
investments made by the suppliers will also be operational during
2007.

In May Wärtsilä and Vietnam Shipbuilding Industry Corporation
(Vinashin) signed a licence agreement for the manufacture and sale of
certain types of Wärtsilä low-speed engines in Vietnam. The first
engine delivery is scheduled for the beginning of 2010.

Wärtsilä's joint venture company in China, Wartsila CME Zhenjiang
Propeller Co Ltd, opened its new fixed pitch propeller factory in
June. The new factory doubles Wärtsilä's capacity to manufacture this
type of propeller.

The manufacturing and technology activities of the propulsor business
are being merged with the engine manufacturing into an Industrial
Operations organization. The target of the new structure is to
further strengthen untilization of core competences.

R&D
Wärtsilä is further increasing its focus on combustion research and
engine performance technology development by making new investments
in this area.

The current Hercules programme aiming at reduction of fuel
consumption and CO2 emissions ends in September 2007. The main
parties in the present programme, Wärtsilä and MAN Diesel, are
preparing the next phase of the project. The proposal for the next
phase was submitted to the EU Commission at the beginning of June.

Testing of the Wärtsilä Auxpac 26 engine began during the review
period with positive results. This product will enhance the Auxpac
product range to meet market demand for bigger auxiliary engines.

PERSONNEL
Wärtsilä had 14,791 (12,650) employees on average during the
reporting period and 15,180 (12,918) at the end of June. The largest
personnel increases took place in the Services business where the
personnel increase was close to 19% compared to the correponding
period 2006. At the end of the period the Services business employed
8,937 (7,537).

ORGANIZATION OF THE BOARD OF DIRECTORS
The Board of Directors of Wärtsilä Corporation elected Antti
Lagerroos as its chairman and Göran J. Ehrnrooth as the deputy
chairman. The Board decided to establish an Audit Committee, a
Nomination Committee and a Compensation Committee. The Board
appointed from among its members the following members to the
Committees:

Audit Committee:
Chairman Antti Lagerroos; Members Maarit Aarni-Sirviö, Heikki Allonen
and Matti Vuoria.

Nomination Committee:
Chairman Antti Lagerroos; Members Göran J. Ehrnrooth and Matti
Vuoria.

Compensation Committee:
Chairman Antti Lagerroos; Members Heikki Allonen and Matti Vuoria.

RISKS AND BUSINESS UNCERTAINTIES
The very high demand has led to a short supply of certain key
components. Examples of bottlenecks are castings and forgings where
global demand exceeds supply. Wärtsilä has taken several measures to
ensure the availability of these key components. Investments have
been implemented by many of the company's suppliers and most of these
will be operational during 2007.

MARKET OUTLOOK
The outlook for the global world economy remains strong and is
expected to remain favourable in the near future. The shipping and
shipbuilding industries continue to be active. The freight market has
remained strong and freight rates are still at historically high
levels. Slightly higher interest rates and inflation have not
affected the shipbuilding market. However, the increase in deliveries
of new ships has become faster than growth in demand for new tonnage
and this is expected to start affecting the freight market in the
medium term. The market is expected to continue active at least for
upcoming six months. Also offshore investments in both vessels and
various production units are expected to remain at a high level for
at least half a year.

In the Power Plant market the situation remains good. Order intake is
expected to remain high during the reminder of the year with
particularily good prospects in South Asia, Africa and the Americas.

WÄRTSILÄ'S PROSPECTS FOR 2007
Demand in the ship power and energy markets looks likely to remain
active for Wärtsilä for the next two quarters. Based on the strong
order book, Wärtsilä's net sales are expected to grow this year by
around 15%. Profitability will exceed 9%. Wärtsilä's profitability
varies considerably between the quarters as will also be the case
this year. Wärtsilä sees further possibilities for growth in 2008.

WÄRTSILÄ INTERIM REPORT JANUARY - JUNE 2007

This interim financial report is prepared in accordance with IAS 34
(Interim Financial Reporting) using the same accounting policies and
methods of computation as in the annual financial statements for
2006. All figures in the accounts have been rounded and consequently
the sum of individual figures can deviate from the presented sum
figure.

Use of estimates
The preparation of the financial statements in accordance with IFRS
requires management to make estimates and assumptions that affect the
valuation of the reported assets and liabilities and other
information, such as contingent liabilities and the recognition of
income and expenses in the income statement. Although the estimates
are based on the management's best knowledge of current events and
actions, actual results may differ from the estimates.

Amended and new International Financial Reporting Standards (IFRS) as
of 1
January 2007:

-        IFRS 7, financial instruments: Disclosures
-        Amendment to IAS 1, Capital disclosures
-        IFRIC 8: Scope of IFRS 2
-        IFRIC 9, Reassessment of Embedded Derivatives
-        IFRIC 10, Interim financial Reporting and Impairment.

The adoption of the new and revised standards and interpretations
does not have any material affect on the interim financial report.

This interim report is unadited.
