Media release | 20 August 2025 | Sensirion Holding AG, 8712 Stäfa, Switzerland | Ad hoc announcement pursuant to Art. 53 LR
Financial Highlights
The first half of 2025 closed with sales of CHF 184.5 million, representing an organic revenue increase of 45.5% in local currencies and 44.2% in Swiss francs compared to the same period last year. This growth was driven by the ramp-up of A2L leakage sensors for air conditioning systems in the US and increased demand for environmental sensors from China and the broad distribution network. Gross margin reached 51.5%, a significant increase from the previous year. The EBITDA margin also saw a substantial rise to 19.8%.
Sensirion reaffirms its forecast for the 2025 financial year, narrowing the revenue guidance to CHF 320 to 340 million, assuming stable economic conditions.

Market Performance and Growth Drivers
Sensirion recorded significant revenue and profit increases in the first half of 2025, despite political turmoil. Growth was primarily driven by the continued ramp-up of A2L leakage sensors for air conditioning systems in the US and increased demand for environmental sensors from China and the distribution network. Three out of four end markets experienced substantial year-on-year growth, with prior-year figures partly affected by inventory corrections. The automotive market remained flat, reflecting challenges in the Western automotive industry.
The US tariff situation has a limited direct impact due to US customer facilities being located outside the US and tariff exemptions for semiconductors. Sensirion's diversified global production footprint provides flexibility.
Revenue Growth by Segment:
- Automotive: Revenue was flat (CHF 39.3 million, -1% YoY), impacted by industry challenges. Sensirion anticipates renewed growth driven by its product pipeline, especially in electric vehicles.
- Medical Technology: Revenue increased by 56% to CHF 28.5 million, driven by new projects and recovery in CPAP and ventilation business, which was previously affected by inventory corrections.
- Industrial Market: Revenue grew by 69% to CHF 107.0 million, primarily due to the ramp-up of A2L leakage sensors for air conditioning systems in the US, a business that has now completed its ramp-up phase. Demand for other established applications also contributed, supported by Chinese government subsidies.
- Consumer Market: Grew by 54% to CHF 9.7 million, supported by inventory normalization and increased demand for environmental sensors from China.
Growth Strategy and Operations
Sensirion is progressing with its ambitious growth strategy, focusing on innovation and technological leadership. Key initiatives include:
- Strategic Focus 1: Consolidating and enhancing market position in environmental and flow solutions with new product innovations, such as the chip-based CO2 sensor for indoor air quality monitoring.
- Strategic Focus 2: Unlocking adjacent applications and business areas by leveraging its technology portfolio and customer base. This includes developing other leakage sensors for automotive and industrial markets, and becoming a leading service provider for methane emission monitoring in the oil and gas industry through its subsidiary Sensirion Connected Solutions (SCS), which recently acquired Kuva Systems.
Operationally, Sensirion is strengthening resilience by focusing its Swiss plant on highly automated component manufacturing and utilizing production sites in Hungary, China, Korea, and Mexico for module production. This strategy aims to increase globalization and reduce dependence on the Swiss franc.
Full-Year Outlook
Despite global economic deterioration, US trade policy uncertainty, and a depreciating US dollar, Sensirion reaffirms its 2025 financial year forecast. The company expects consolidated revenue between CHF 320 to 340 million (FY 2024: CHF 276.5 million), representing projected organic growth of 16% to 23%. The EBITDA margin is expected to remain within the mid- to high-teen percent range.
A moderate reduction in demand for A2L leakage sensors is anticipated in the second half of the year due to supply chain adjustments and the partial phase-out of stimulus programs in China.
