What Tonner Drones does
Tonner Drones is a French public holding company listed on Euronext Access Paris under ticker ALTD (formerly associated with the Delta Drone brand), headquartered at 27 avenue de l'Opéra, Paris. The company operates a hybrid model that combines a single operating product, Countbot, with a portfolio of minority equity stakes in specialized drone manufacturers and adjacent industrial assets. Countbot is an automated warehouse-inventory drone solution developed in close collaboration with logistics group GEODIS, designed to replace manual inventory counting with automated drone flights that produce WMS-compatible stock data; it is commercialized through three channels — direct purchase (with bundled training, service contract, and maintenance), monthly leasing (including setup and operator training), and on-demand service (Tonner Drones operates the inventory visits on a pay-per-engagement basis). The company also holds minority stakes in Elistair (11.43%, tethered surveillance drones deployed in 70+ countries), Donecle (10.30% retained after a partial exit, automated aircraft inspection drones listed in Airbus and Boeing AMMs), Diodon (8.4%, waterproof microdrones for maritime defense), Roth Mions (18.7%, ultra-high-pressure gas storage), and SpaceX (strategic position taken in January 2026). The business model generates revenue from Countbot sales/leasing/service fees, investment-portfolio appreciation and partial exits, and potentially future royalties or sale of the 'Inhibitor' patent. In 2025 the company completed a financial restructuring that reduced operating expenses by 76% to €778,000 and shifted it to a €1.1M net profit from a €5.6M loss the prior year.
