Business
Groupe Tera SA (ALGTR.PA) is a France-based provider of real-time air quality measurement and analysis solutions. The company, founded in 2001 and headquartered in Crolles, operates through subsidiaries including TERA Sensor, Omwave, and Atmotrack, offering advanced sensors such as the NextPM series for PM1, PM2.5, and PM10 monitoring with patented humidity control technology; NextPM Advanced for HVAC and industrial applications with external pump integration; SafyrOPC optical particle counters compliant with ISO 21501-4 for cleanroom environments in pharmaceuticals, biotech, semiconductors, and aerospace; PMSCAN personal exposure monitors; PMDUCT in-duct solutions; custom OEM sensor integration, prototyping, product development, and certification services; digital cloud applications for real-time data analysis; and air and respiratory protection technologies. It serves markets including smart cities, smart industry, cleanrooms, giga factories, environmental monitoring, home automation, and transportation, with operations primarily in France and international expansion focus. In October 2025, Groupe Tera completed the sale of its chemical analysis laboratories TERA Environnement and Toxilabo to CELNOR France, representing 84% of prior revenue, to strategically refocus on real-time measurement activities, strengthen its balance sheet by repaying most debts, accelerate new product industrialization, and launch a 13 million euro share buyback offer at 6.5 euros per share in Q4 2025, reducing headcount from approximately 110 to 30 employees.
