In the interim report published on August 11, 2009, Vaisala estimated that its net sales in 2009 will grow slightly compared to the preceding year. It was further stated that uncertainty towards the rest of the year has increased due to the schedules of project sales and deliveries as well as the development of demand in the industrial segments.
 
Based on recent information Vaisala is decreasing its sales estimate. The current view is that net sales in 2009 will be slightly lower than in 2008. The main reason for this is lower than expected order intake to be invoiced in the fourth quarter, especially in project sales. There is still uncertainty relating to the rest of the year in terms of project sales and deliveries and the development of the demand in the industrial segments.
 
Due to the structure of Vaisala's customer base, the market situation is expected to remain unchanged, and order cancellations are not anticipated. The long term business outlook has not changed and Vaisala is still fully committed to continuing the implementation of its growth strategy.
