About Sensirion Holding AG

Sensirion Holding AG is a Swiss high-technology company listed on the SIX Swiss Exchange (SMI/SPI) and headquartered in Switzerland, in Stäfa near Zurich. Founded in 1998 as an ETH Zurich spin-off by Moritz Lechner and Felix Mayer, the group has built a strong reputation as a specialist in semiconductor-based sensor solutions. Its business model is centered on environmental sensing and flow measurement, with a high degree of vertical control across the value chain: sensor wafers are designed in-house, production is partly outsourced to foundries, and final processing, calibration and testing are handled through Sensirion’s own manufacturing capabilities. This structure supports product quality, technology control and operational flexibility. Sensirion’s core activities focus on sensors for environmental parameters, gas flow, liquid flow and machine diagnostics. The company serves several end markets, including automotive, medical technology, industrial applications, building and HVAC, and consumer electronics. Its portfolio includes humidity and temperature sensors, CO2 sensors, air-quality modules, flow sensors and related sensing solutions. The group operates primarily as an OEM supplier, meaning its components are integrated into customers’ devices rather than sold as standalone consumer products. This is important from an investment perspective because it ties revenue opportunities to customers’ product cycles, but also creates sticky technical relationships and a broad embedded installed base. From a competitive standpoint, Sensirion occupies a differentiated niche in precision sensing, where accuracy, miniaturization, reliability and ease of integration matter as much as cost. The company’s international footprint is broad, with offices and operational presence in China, Germany, Hungary, Japan, Singapore, South Korea, Taiwan, the Netherlands and the United States, while Switzerland remains the center of gravity for headquarters, engineering and key industrial activities. This geographic setup allows the group to support global customers while maintaining a strong Swiss industrial and innovation base. Recent developments suggest that Sensirion continues to execute in a still demanding market environment. At the annual general meeting on 12 May 2025, management reported that fiscal 2024 delivered strong revenue growth thanks to new business wins, and shareholders approved all proposals put forward by the board. In 2025, the company also advanced its product pipeline with launches and availability announcements across environmental sensing, CO2 monitoring and methane-emissions monitoring through Sensirion Connected Solutions. For investors, Sensirion represents a quality Swiss technology name on the SIX Swiss Exchange (SMI/SPI), with exposure to long-term structural themes such as energy efficiency, indoor air quality, industrial digitalization and sensor-driven automation.
