Sensirion Holding AG Stock: price and insider trades · Switzerland

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.
