Vaisala now estimates its full-year 2026 net sales to be in the range of EUR 610–630 million and EBITA to be in the range of EUR 110–120 million. Vaisala’s net sales and profitability in the third quarter and during January–September 2026 were driven by the very strong performance of the Industrial Measurements business area. The business area’s improved profitability and its growing share of the Group’s net sales positively impacted Vaisala’s EBITA. Growth in Industrial Measurements’ net sales during the third quarter of 2026 was driven by strong demand from the data center, semiconductor, battery manufacturing, and power industries. In addition, U.S tariff refunds and lower tariff levels positively impacted Vaisala’s profitability in the third quarter and during January–September 2026. The tariff refunds from 2025, which are reported under Corporate and non-operative items, contributed EUR 4 million to Vaisala’s EBITA in the third quarter of 2026. Vaisala’s third quarter 2026 and January–September 2026 preliminary net sales and EBITA were: Net sales <table style="border-top: solid black 1pt ; border-right: solid black 1pt ; border-bottom: solid black 1pt ;
