Overview
Financial overview
Equity research
Vaisala’s Q3 results beat estimates due to W&E projects. IM has solid earnings drivers for next year as well, although its Q3 EBITA turned out a bit soft relative to our estimates, but W&E EBITA is unlikely to hit new record highs for a while yet.
Vaisala’s Q3’25 results were clearly better than estimated in terms of both revenue and profitability, however there were still some mixed underlying developments as W&E saw continued weak orders and yet was able to post relatively strong results for the quarter. IM’s Q3 earnings were a bit soft relative to estimates, but its outlook remains strong going forward.
Vaisala reports Q3 results on Oct 23. W&E is likely to see its earnings decline in H2 as well, while IM could still help Vaisala to achieve modest earnings growth also this year.
Vaisala’s Q2 fell short of our estimates due to weaker than expected performance in W&E. Although W&E faces headwinds from various sources, IM momentum continues.
W&E headwinds had a greater impact than we anticipated in Q2, resulting in net sales coming in slightly below our estimate at EUR 145.0m (Evli est. EUR 148.9m). Lower volumes led to decreased profitability compared to the strong Q2 last year, with EBITA at EUR 19.6m (Evli est. EUR 22.5m).
Vaisala reports Q2 figures on 25th of July. The company faces strong comparison figures, particularly within its W&E business. Furthermore, uncertainty surrounding its US operations remains elevated.
Strong performance in the first quarter gave Vaisala a solid start to the FY but the ongoing trade uncertainties will likely challenge it during the rest of the year.
Vaisala’s Q1 net sales were approximately in line with our estimates at EUR 135.6m (Evli est. EUR 133.5m), while the company’s profitability beat our estimates by a wide margin as EBITA climbed to EUR 20.5m (Evli est. EUR 14.2m).
Vaisala reports its Q1 figures on 24th of April. The escalating trade war increases uncertainty in the short-term. While direct impacts seem relatively limited, indirect effects are likely to hit, with the scale still unclear. The Q1 should remain unaffected while we focus on the comments regarding the outlook.
Vaisala’s 2024 ended on a strong note as was expected after January’s positive profit warning. We continue to see many tailwinds for the company in 2025E, yet uncertainties remain.

Business outlook for 2025

As of 2025, in its outlook, Vaisala has changed EBIT to EBITA to align with its long-term financial targets.
Market outlook for 2025
Markets for industrial, life science, and power grew during the first three quarters of the year. Similar development is expected during the rest of the year. However, the market environment remains uncertain, affecting the predictability of these market segments' development.
More mature market segments – meteorology, and aviation – are expected to decline compared to exceptionally high levels in the previous two years. The market for renewable energy is expected to decline during this year due to a slow-down in new wind energy projects. The roads market segment is expected to be stable.

*Excluding impact of acquired businesses
President and CEO Kai Öistämö
“Vaisala delivered strong net sales and profitability in the third quarter, while order intake declined. Our net sales increased in both business areas, as Industrial Measurements continued to grow and Weather and Environment achieved very strong net sales, driven by large project deliveries as well as subscription sales.
Demand continued strong in the Industrial Measurements business area. However, Vaisala’s third quarter order intake declined by 21% year-on-year due to weak demand in the Weather and Environment business area, which also faced a strong comparison period. Our net sales increased very strongly by 13%, with both business areas contributing to this growth. The depreciation of the US dollar and Chinese yuan against the euro had a negative impact on our reported net sales. In constant currencies, our net sales grew by 16% year-on-year. We were largely able to offset the impact of the US tariffs through price increases. We maintained solid profitability, achieving a 20% EBITA margin, excluding EUR 3.0 million restructuring costs related to organizational changes.
The Industrial Measurements business area delivered yet another strong quarter, achieving positive results across all market segments. Orders received increased by 9%, fueled by very strong growth in the EMEA and APAC regions. Net sales grew by 6% (10% in constant currencies), with the APAC region leading the growth.
The Weather and Environment business area had a very strong quarter in net sales, driven by large project deliveries in the meteorology market as well as subscription sales in the Xweather business. Weather and Environment net sales increased by 18% (20% in constant currencies) compared to the previous year. However, order intake continued to be impacted by weak demand in the renewable energy market, as well as by industrial cyclicality and reductions in public sector spending compared to the exceptionally high levels last year. We have implemented necessary cost-control measures and adjusted our organization to address the significant change in demand in the renewable energy market. Decisions impacting our people are never easy, but this restructuring has been a necessary step to adapt to the new market reality.
In September, we acquired Quanterra Systems, a company specializing in atmospheric monitoring of CO2 fluxes, to expand our capabilities in greenhouse gas measurements.
Subscription sales in our Xweather business grew by 57% in the third quarter. Underlying organic growth in constant currencies was also a solid 14%. Over the past quarters, we have seen subscription sales contributing positively also to our profitability. We continuously strengthen and upgrade our offerings, with one recent example being the launch of advanced hail forecasts.
As we move into the fourth quarter, we anticipate that global market uncertainty will remain, making future market developments difficult to predict. We continue to monitor the overall global market situation and are prepared for different scenarios to mitigate possible impacts on our business. Despite market uncertainty, we continue to estimate, excluding potential significant changes in market conditions, that our full-year 2025 net sales will be in the range of EUR 590–605 million and EBITA will be in the range of EUR 90–100 million.”

Press release
September 2, 2025
Vaisala acquires Quanterra to kick off its New Climate Business
In the face of political uncertainty and climate skepticism, the world’s leading measurement technology firm, Vaisala, emphasizes the need for proof and transparency. The company is expanding its business in greenhouse gas measurements and announces the acquisition of its client, Quanterra Systems Ltd, a company specializing in atmospheric monitoring of CO2 fluxes.
Climate initiatives are facing a publicity problem. Greenwashing is eating away at public trust in companies’ sustainability initiatives. And rightfully so: according to a Nature Communications meta-study in November 2024, more than 80 percent of voluntary-market carbon credits deliver far less climate benefit than advertised.
Fernando Trolia Slamic, the recently appointed Head of Vaisala’s New Climate Business, says it all boils down to transparency and scientific proof.
“Without knowing exactly how much greenhouse gas is emitted or sequestered into nature, companies and institutions struggle to know their true climate impact or to communicate facts truthfully to their stakeholders,” says Trolia Slamic.
To offer a solution, Vaisala today announced the acquisition of its client Quanterra, and with it, the official start of its New Climate Business.
Measuring carbon sinks is essential for global climate efforts
Quanterra offers site-specific atmospheric carbon monitoring for nature-based industries such as agri-food and biofuels, as well as public and private research communities, including carbon certification and trading markets. In practice, the company deploys and operates networks of measurement towers at its customers’ locations to directly and continuously monitor atmospheric flows of carbon, water, and energy at the site. The data on these flows, also known as fluxes, is then analyzed for the customer with proprietary methods, and the service is billed as an affordable annual subscription.
Quanterra customers can utilize the real-time data collected over long periods of time as verification for the effectiveness of their low-carbon products and programs. Reliable on-site data can also be used to support the generation of high-quality carbon credits for the carbon trading market, offering a new revenue stream to agricultural operators and other managed nature assets.
Founded in 2021, Quanterra is a spin-out from the University of Exeter. The revenue in 2024 was more than GBP 1.2 million, and the business is EBITDA positive. The company currently employs 14 people.
“Even though the business is in early stages, we see great potential for future growth. The planet needs a solution like this. Emission reductions alone will not be sufficient to fight climate change – we also need verified carbon sinks. Reliable measurements will also help re-establish public trust towards climate action,” says Anne Jalkala, Executive Vice President of the Weather, Energy and Environment business at Vaisala.
“Vaisala’s sensors have been a key part of Quanterra’s solution from the very start, and we are well aligned for the future. With Vaisala's experience and muscles, we will be able to scale the business faster than would have been possible by ourselves. Their global field service coverage will also enable us to help new customers more affordably in areas like Australia, South America, and Asia,” says Rebecca Mitchell, CEO of Quanterra.
Eyes open for opportunities in GHG measurements
Vaisala has long been at the forefront of enabling climate action through measurement technology. Among others, Vaisala’s instruments and data are utilized in setting up and operating wind and solar farms. The company also helps industrial clients like data centers and battery manufacturing to save resources by optimizing their production and energy consumption.
Vaisala revolutionized carbon dioxide measurements with its infrared sensing CARBOCAP® sensors almost 30 years ago. Today, these sensors are used in carbon monitoring research and pilots around the world. Based on the same technology, the company launched a new measurement instrument last year that is specifically designed to measure CO2 and humidity in carbon capture, utilization, and storage (CCUS) projects.
“There is a lot we already do to help the world become more sustainable. Carbon flux monitoring is another bold step for us to fulfill our purpose of taking every measure for the planet. Our New Climate Business team drives Vaisala’s current and future greenhouse gas measurement offering – and we’re only getting started,” Trolia Slamic says.
