Investor relations

At its Investor Day event today, April 14, 2026, Sensirion will offer in-depth insights into its strategy, its priority growth areas and its long-term approach to value creation and capital allocation.

Sensirion closed the 2025 financial year in a highly challenging market environment with revenue of CHF 342.4 million, slightly above guidance. This corresponds to a year-on-year increase of 29.2 % in local currencies and 23.8 % in Swiss francs compared with the previous year. EBITDA more than doubled compared to adjusted 2024, underpinned by strong cash conversion. The biggest growth driver was A2L leakage sensors for air conditioning systems in the US. However, market share was also gained in other applications, with three of the four end markets recording significant growth. At the same time, Sensirion is benefiting from broadly diversified growth areas in all end markets, which made noticeable progress in the reporting year. Thanks to its strong pipeline, innovative technologies, clear strategic priorities and high industrial resilience, Sensirion is well positioned to achieve sustainable growth in the coming years in the strategically relevant areas of leakage detection, advanced medical sensor solutions and industrial gas analysis.

The first half of the year closed with sales of CHF 184.5 million. This represents 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 mainly by the continued ramp-up of A2L leakage sensors for air conditioning systems in the US, as well as increased demand for environmental sensors from China and the broad distribution network. This resulted in substantial year-on-year growth of over 50% in three of our four end markets. At 51.5%, the gross margin is significantly higher than in the same period of the previous year. The EBITDA margin increased significantly to 19.8%.

Sensirion is reaffirming the forecast for the 2025 financial year, but is narrowing the revenue guidance symmetrically: assuming stable economic conditions, the company now expects consolidated revenue of CHF 320 to 340 million.
