What Imerys does

Imerys S.A. is a publicly traded French specialty minerals company (Euronext Paris: NK) founded in 1908 with its first carbon manufacturing operation in the Swiss canton of Ticino. The company mines or processes more than 30 different minerals drawn from over 100 mineral deposits globally, holding world #1 positions in andalusite, diatomite, expanded perlite, calcined refractory products, graphite conductive additives, and conductive carbon black, plus world #2 in calcium carbonates. It operates across 21+ countries on five continents, with headquarters in Paris and dedicated technology centers in France, Switzerland, China, Japan, the United States, and Austria, while maintaining an average of 20 years of mineral reserves.

The company's core capabilities span mineral extraction, high-temperature processing for fused and calcined products, synthetic graphite production with over 99% carbon purity, proprietary CVD coating for carbon-coated graphite, and engineered mineral formulation. Imerys sells both mineral commodities (calcium carbonate, talc, kaolin, bentonite, perlite, diatomite, etc.) and specialty engineered solutions marketed under brands such as ALODUR®, ImerCare®, MULCOA®, Timrex®, C-NERGY™, FilmLink®, Celite®, and SECAR®. Its horizontal go-to-market serves ten or more end markets including ceramics, refractories, batteries and fuel cells, construction, cosmetics, food and beverage, pharmaceuticals, abrasives, advanced ceramics, and animal care, with technical-services and formulation-support bundled into product sales.

Revenue is generated through B2B direct enterprise sales of mineral products to industrial customers, primarily via multi-year contracts negotiated on volume, specifications, and long-term supply arrangements. Distribution relies on Imerys's owned mines, processing plants, and logistics infrastructure spanning EMEA, North America, South America, and Asia Pacific. Recent strategic moves include the January 2025 acquisition of Chemviron's European diatomite and perlite assets, the June 2026 acquisition of Great Lakes Minerals in the United States, the February 2026 French State equity participation in the EMILI lithium project at Beauvoir (targeting 34,000 tonnes/year of battery-grade lithium hydroxide), and the early-2026 placement of the British Lithium project into care and maintenance pending a long-term partner.
