About STIF
STIF is a French industrial group listed on Euronext Growth Paris under ISIN FR001400MDW2 and ticker ALSTI. Founded in 1984, the company originally built its business around equipment for bulk material handling, then progressively diversified over the past decade into higher value-added niche markets. Today, STIF is positioned as a specialist in the design, manufacture and marketing of innovative industrial solutions, with a particularly strong focus on passive protection against industrial dust explosions and, since 2022, on protection systems for Battery Energy Storage Systems, or BESS. This strategic shift reflects the company’s alignment with energy transition themes and with the growing demand for industrial safety.
STIF’s product portfolio is largely built around proprietary brands such as Vigilex, Vigilex Energy and Manubulk. These ranges address a broad set of needs, including explosion vent panels, flameless explosion protection devices, explosion isolation solutions, dust-tight inspection doors and other components used in bulk handling applications. The group emphasizes that its products are marketed in more than 80 countries, highlighting both its export intensity and the international recognition of its technical expertise. STIF also reports a network of around 30 partner distributors and a modern industrial footprint distributed across France, Asia and the United States.

From a strategic standpoint, STIF is targeting sustained growth, with a stated ambition to reach €200 million in revenue by 2030. In 2024, the group generated €61.2 million in sales, up 72.3% year on year, including €29.3 million from the BESS segment, confirming the rapid scaling of this activity. The company also notes that 87% of revenue is generated outside France, with particularly strong positions in North America and Asia. The United States has become a major growth engine, supported by a production unit in Texas designed to serve the fast-growing North American market. One notable fact is that STIF claims to be the first French company certified to ATEX EN16009:2011 for flame arresters, and the only European company to hold this certification for rectangular flame arresters. Combined with its export reach, specialized engineering know-how and exposure to renewable-energy infrastructure, STIF stands out as a distinctive industrial listed company in France.
