Instability of the global economy and shifts in the exchange rates are still expected to affect Vaisala's business. Due to the structure of Vaisala's customer base and the orders received, the company's market situation is expected to remain mostly unchanged and the business stable in 2010.

Vaisala expects its net sales in 2010 to grow slightly from the preceding year. Also profitability is expected to improve slightly. Strategic, growth oriented efforts will continue and burden Group profitability also this year.

The QTT acquisition is not expected to have a significant impact on the operating profit in 2010.

Seasonal fluctuation is typical of Vaisala's business, so the first quarter appears to be moderate.

The long term business outlook has not changed and Vaisala is still committed to continuing the implementation of its growth strategy.
