Full-Year Results 2019

Sensirion experienced a challenging 2019 as a result of the reduced demand and increased volatility in all markets, especially in the first half of the year.

In the second half of the year, the start of new business put Sensirion back on a moderate growth path, which made up for part of the decline in sales during the first six months. At CHF 171.0 million, consolidated revenue was slightly higher than expected in summer 2019 (-2.2 % year-on-year), the gross margin was stable at 53.7 %, and the EBITDA margin adjusted for one-time effects amounted to 12.0 %. Sensirion confirms its medium and long-term growth prospects based on the long-term trends in the markets as well as its full product and project pipeline.
