Comments on the first quarter

Orders received are at a good level with slight growth year on year.
The first quarter is typically weaker than the subsequent ones.

Vaisala's net sales were lower than a year ago due to project
deliveries that were postponed to second and third quarter. The
markets of the Controlled Environment business area, i.e. industrial
measurement segments declined at the beginning of the year. Group
operating profit was negative due to lower net sales and costs
incurred by growth-oriented strategic initiatives.


Outlook

Due to the structure of Vaisala's customer base, the company's market
situation is expected to remain mostly unchanged in 2009 and there
are no signs of order cancellations. However, the demand has slowed
down for the industrial segments which are more sensitive to economic
fluctuations. These segments represent approximately 25 percent of
Vaisala's net sales. The weakening of these segments may continue,
shifting their growth expectations to a later stage.

The outlook for the weather segments, i.e. Meteorology and Weather
Critical Operations business areas is still good. However, schedules
of the delivery projects may be delayed which increases uncertainty
towards the rest of the year.

We reiterate our estimate that Vaisala's net sales in 2009 will grow
slightly compared to the preceding year. We expect that the
operational profitability will remain at a good level, but the
strategic, growth oriented efforts will burden Group profitability
this year by approximately EUR 10 million. With these efforts Vaisala
aims to maintain its technological leadership, make processes more
efficient and reduce manufacturing costs.



President and CEO Kjell Forsén on Vaisala's result:"Despite the uncertainties in the global economy, the number of
orders received and order book exceed last year's level, which gives
us a good starting point for the rest of the year.

The first quarter was a slight disappointment. However, we still
expect to see growth in 2009 because our order backlog is strong and
the basic business environment has not changed substantially. Both
net sales and operating profit declined year on year. The decline in
net sales was largely due to some postponed project deliveries in
Weather Critical Operations, which are due to take place in the
second and third quarter, and the slightly lower sales in the
industrial segments. Our operating profit declined because of lower
sales and because of costs incurred by the growth initiatives.

We continue to execute Vaisala's growth strategy this year, which
will result in increased costs. We are especially going to strengthen
our research and development capabilities and sales organization to
support our businesses globally. Additionally the sizeable
ERP-development project is progressing. We consider the current
situation highly suitable for taking measures that aim to improve our
future position. Vaisala's strong balance sheet enables this. We
believe that when the world economy starts recovering, these efforts
will further strengthen our competitiveness in the markets."


Market situation, net sales and order book

Instability of the world economy shows especially in the Controlled
Environment business area, i.e. in the industrial segments, where the
markets declined at the beginning of the year. Vaisala has
nevertheless been able to retain its market shares.

The outlook for Meteorology and Weather Critical Operations business
areas, i.e. the weather segments, is still favorable and the demand
is expected to remain good.

Vaisala Group's net sales declined by 9.4 percent on the comparison
period and totaled EUR 42.1 (46.4) million. Net sales of the
Meteorology business area grew by 25.0 percent, whereas the net sales
of Weather Critical Operations declined by 32.8 percent and
Controlled Environment by 6.6 percent. In comparable currencies,
Vaisala group's net sales would have been down by 14.7 percent.

Operations outside Finland accounted for 97 (96) percent of net
sales.

Net sales in euros remained at last year's level in the Americas
region, totaling EUR 15.8 (15.8) million. Net sales declined by 12.0
percent to EUR 16.3 (18.5) million in the EMEA region and by 17.9
percent to EUR 9.9 (12.1) million in the APAC region. In comparable
currencies, the changes in net sales have been: Americas -12.6%, EMEA
-9.2% and APAC -24.5%.

The value of orders received grew by 3.5 percent year on year and
totaled EUR 66.1 (63.9) million. The number of orders received for
the past 12 months is EUR 250.1 million. The order book stood at EUR
114.4 million (96.0) at the end of the review period.


Performance and balance sheet

Operating profit for the financial year was EUR -3.1 million (3.1),
or -7.4 percent of net sales. Profit before taxes was -10.0 percent
of net sales and totaled EUR -4.2 (2.9). Net profit for the review
period was -10.0 percent of net sales, totaling EUR -4.2 (1.9)
million.
Vaisala Group's solvency ratio and liquidity remained strong. On
March 31, 2009, the balance sheet total was EUR 233.9 (220.0)
million. The Group's solvency ratio at the end of the review period
was 76% (78%).

Vaisala's consolidated liquid assets totaled EUR 97.1 (100.2)
million.


Capital expenditure

Gross capital expenditure totaled EUR 6.5 (2.1) million.

In January 2009, Vaisala acquired all shares of Aviation System
Maintenance Inc (ASMI), a US-based airport service company. The
company has 10 employees and the estimated net sales for 2008 were
EUR 1.8 million. ASMI, which is located in Kansas, has a large
customer base and over 25 years of experience in the installation and
maintenance of airport weather equipment.

The acquisition will considerably strengthen Vaisala's position as a
supplier of maintenance services in the US airport weather business,
complementing the existing service contracts and expertise. According
to preliminary calculations, these synergy benefits have accrued to
EUR one million goodwill. The deal price was EUR 2.4 million, which
includes a conditional EUR 0.5 million deal price. This conditional
price will be paid at the end of 2010, provided that certain
performance expectations are met.

Vaisala's new ERP system is gradually taken into use during this and
next year. The project to build new office space in Vantaa, Finland
is progressing according to plans. The old building will be torn down
during the second quarter of 2009.


Changes in financial reporting

Vaisala published its new strategy in November 2008. Going forward,
the company will focus on markets with the biggest growth potential
in the environmental measurement business. The company will seek
growth from the current and new market segments. Vaisala also
announced that it adopts a market segment based reporting model. From
the first interim report in 2009, Vaisala Group's business will be
reported in three segments, which are Meteorology, Weather Critical
Operations and Controlled Environment. From the beginning of 2009,
the Group adopted the amended IAS 1 Presentation of the Financial
Statements standard and IFRS 8 Operating Segments standard. The
amended standards have no significant impact on the presentation of
the interim report.

Meteorology

Meteorology consists of Emerging markets and Established markets. The
Meteorology business area serves national meteorological and
hydrological institutes, whose primary interest is to provide
national weather information and forecasts.

Net sales of Meteorology grew by 25.0 percent year on year to EUR
15.8 (12.6) million. In comparable currencies, the net sales would
have grown by 17.2 percent. Operating profit was EUR 0.6 (-0.2)
million.

The value of orders received for Meteorology was EUR 22.8 million and
the order book stood at EUR 48.1 million at the end of the review
period.

A major part of the modernization project for the Russian weather
observation network was delivered during the first quarter.


Controlled Environment

Controlled Environment consists of Cleanrooms and Chambers, Building
Automation and Targeted Industrial Applications segments. This
business area includes customers who operate in tightly controlled
and demanding areas where the measurement of precise environmental
conditions is required to increase operational quality, productivity
and energy savings.

The instability of the global economy was reflected in the Controlled
Environment business area, where the markets declined especially in
Japan and North America. Net sales of Controlled Environment declined
by 6.6 percent year on year to EUR 12.8 (13.7) million. In spite of
declined net sales, Vaisala has been able to maintain its market
shares. In comparable currencies, the net sales would have been down
by 15.5 percent. Operating profit in January-March was EUR 1.2 (2.7)
million.

The value of orders received for Controlled Environment was EUR 12.6
million and the order book stood at EUR 3.2 million at the end of the
review period.


Weather Critical Operations

Weather Critical Operations consists of Airports, Roads, Defense,
Wind Energy and Targeted Business Development segments. This business
area focuses on customers whose operations or businesses are affected
by the weather, like aviation customers, road authorities, defense
forces and wind parks.

Net sales of Weather Critical Operations declined by 32.8 percent
year on year to EUR 13.5 (20.1) million. In comparable currencies,
the net sales would have been down by 34.2 percent. Operating profit
for the review period was EUR -4.4 (-0.2) million. The result was
mostly burdened by delayed deliveries of weather radar signal
processors and weather observation systems for airports. The revenue
of these deliveries is expected to be recognized during the second
and third quarters.

The value of orders received for Weather Critical Operations was EUR
30.7 million and the order book stood at EUR 63.1 million at the end
of the review period.

Vaisala signed a contract with a long standing customer for upper-air
sounding equipment.  The contract was valued at USD 8.6 million and
the deliveries are expected to take place by the end of the first
quarter in 2010.


Other functions

Research and development

Expenditure in research and development totaled EUR 6.5 (6.3)
million, representing 15.5% of the Group's net sales.

The share of research and development expenses of the company's net
sales will grow in 2009. This is due to some one-off projects aiming
at the alignment of technology platforms and improved product
modularity, usability and mass customization capability.

The total additional R&D cost will be approximately EUR 3 million in
2009 and the R&D share will grow to 11-12% of the company's net
sales.

Vaisala announced the development of a reference radio sonde, which
will enable more accurate global observations to monitor climate
change. The project will be carried out in co-operation with the
international climate research community. The sonde will provide
extremely precise weather information from the upper atmosphere.

Vaisala Services

Starting in 2009, Vaisala's service business will be reported as part
of the business areas. Services sales in the first quarter totaled
EUR 7.3 (6.8) million.

In January 2009, Vaisala acquired Aviation Systems Maintenance Inc.
(ASMI) to strengthen its airport weather service offering.


Personnel

The average number of people employed in the Vaisala Group in
January-March was 1,236 (1,121). Some 40 (39) percent of the
personnel was based outside Finland.

Vaisala has two incentive plans; one based on the development of
sales and profitability and covering all employees, and the other,
three-year plan, based on the development of profitability and
covering key personnel.


Changes in Vaisala Corporation's management

Timo Raikaslehto, M.Sc. (Econ.), was appointed Senior Vice President,
Group Marketing and Sales, and a member of the strategic management
group starting March 1, 2009.


Near-term risks and uncertainties

The near term risks and uncertainties are estimated to relate to
changes in the global economy, shifts of currency exchange rates,
interruptions in manufacturing, project delivery capabilities,
changes in purchasing or investment behavior, and delays or
cancellations of orders and deliveries. The biggest risks in
realization of net sales relate to the industrial segments which are
more sensitive to economic fluctuations and where the demand has
clearly slowed down. The share of these segments is approximately 25
percent of Vaisala's net sales.

Significant changes in subcontractor relations, their operations or
operating environment especially due to the uncertainty of the
financial markets may have a negative impact on Vaisala's business.
Vaisala monitors these risks and prepares for them in accordance with
the Company's risk management policy.

The Company is currently implementing significant development
projects and organizational changes, which lay the foundation for
successful execution of Vaisala's new strategy. A new Group-wide
enterprise resource planning system is also under development. These
efforts constitute a short-term risk regarding Vaisala's net sales
and result.
