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.
