Vaisala changes its financial reporting structure and provides comparative information for 2025 according to new reportable segments

Vaisala has decided to change its financial reporting structure as of January 1, 2026, to provide investors with relevant information on its three businesses. In the new structure, Vaisala will report financial information on three reportable segments: the Industrial Measurements business area, the Xweather business area, and the Weather, Energy, and Environment business area.

The Xweather business area has grown by double digits every year since it was established in 2022. This strong growth continued in 2025, driven by organic growth and the acquisitions of WeatherDesk and Speedwell Climate, which closed in Q4/2024 and were integrated into Xweather during 2025. Vaisala aims to grow the Xweather subscription business further in line with the company’s strategy. Therefore, Vaisala wants to increase transparency and provide investors with relevant information on this business area, in addition to its other business areas.

Previously, the reportable segments were the Industrial Measurements business area and the Weather and Environment business area. Xweather, and Weather, Energy, and Environment businesses were part of the Weather and Environment reportable segment.

Additionally, for the Xweather reportable segment, Vaisala will report annual recurring revenue (ARR) as a new alternative performance measure. Annual recurring revenue equals average recurring monthly revenue for the quarter multiplied by twelve, including charges from volume-based contracts. Orders received and order book are not disclosed for the Xweather reportable segment due to the nature of the subscription business. Also previously, orders received and order book did not include subscription business.

Additionally, Vaisala will report certain corporate and non-operative items separately. Corporate items include management costs, which are not directly attributable to the operative activities of the business areas, and non-operative items include one-off costs related mainly to M&A and restructurings, as well as any discontinued businesses. Corporate and non-operative items will not be included in the results of the three reportable segments.

Vaisala’s reportable segments as of January 1, 2026:

The Industrial Measurements business area provides advanced measurement instruments and solutions that help customers across various industries optimize processes, reduce energy consumption, and improve quality and efficiency. The business area has a strong position in humidity, dew point, and carbon dioxide measurements. Key market segments include industrial, life science, and power. 

The Xweather business area provides advanced data and solutions as a service that help businesses manage weather-related risks and optimize operations. By combining local sensor data with AI-driven forecasts, Xweather delivers precise and actionable weather insights to improve safety and efficiency while enhancing resilience against severe weather and climate change. Key market segments include transportation & logistics, energy & utilities, finance & insurance, and developers & data distributors.

The Weather, Energy, and Environment business area provides critical weather and climate observations through advanced instruments and systems. It enables customers – ranging from meteorological institutes and airport operators to renewable energy producers and road authorities – to ensure people’s safety, protection of property, and efficient operations. Key market segments include meteorology, aviation, and renewable energy. 

The following tables present the quarterly and full year 2025 financial information according to the new reporting structure. The figures are unaudited, except for Vaisala group level full year 2025 figures.
