Sensirion Holding AG: Forecast for full-year 2020 raised

One-time COVID-19 related demand for gas flow sensors stronger than expected Based on the stronger than in August 2020 expected development of the medical ventilator-related business year to date, Sensirion Holding AG (Sensirion) raises its outlook for the full-year 2020 again. Revenue is now expected to approximately be CHF 254 million (previously CHF 210-230 million), of which approximately CHF 77 million stem from the ventilator projects (previous year CHF 7 million). The gross margin is projected to improve slightly through economies of scale, while the adjusted EBITDA margin is expected in the mid-twenties percentage range. Despite increased sales in the second half of the year, Sensirion continues to expect demand from the one-time business in connection with the COVID-19 pandemic to normalize from the beginning of 2021. Regular business, not related to ventilator applications, developed as expected in August 2020. More detailed information will be provided when the annual report is published on 16 March 2021.
