Minerals Technologies (symbol: MTX) primarily sells its products and services to other companies (Business-to-Business or B2B) across a wide range of industrial sectors globally.

According to the company's annual reports (e.g., Form 10-K), no single customer accounted for 10% or more of its consolidated net sales in recent fiscal years. This indicates a highly diversified customer base rather than reliance on a few individually named major customers. Therefore, it is not possible to list specific major customer companies by name and symbol based on publicly available information.

Instead, MTX's major customers are best identified by the industries they serve, which collectively form its significant customer base. These include:

• Paper Industry: Manufacturers of paper, paperboard, and packaging products, utilizing MTX's precipitated calcium carbonate (PCC) and specialty minerals for improved brightness, opacity, and other functional properties.
• Steel Industry: Steel manufacturers and other non-ferrous metal producers, relying on MTX's refractory products, systems, and metal treatment chemicals for high-temperature applications in furnaces and ladles.
• Polymer and Plastics Industry: Manufacturers of plastics, films, and composite materials, using MTX's specialty minerals (such as talc and wollastonite) as functional additives, fillers, and reinforcing agents to enhance product performance.
• Foundry Industry: Foundries producing metal castings, utilizing MTX's bentonite and other performance materials for sand binding and mold integrity.
• Construction and Environmental Industries: Companies involved in construction, civil engineering, and various environmental applications (e.g., waste treatment, water purification), using MTX's specialty minerals and performance materials.
• Food and Pharmaceutical Industries: Manufacturers in these sectors, using high-purity specialty minerals as ingredients, processing aids, or excipients.

1. Talc Litigation: Minerals Technologies faces significant financial overhang and lingering legal exposure due to ongoing talc litigation. In the first quarter of 2025, the company recorded a substantial $215 million provision to establish a reserve for current and future talc-related claims.
2. End-Market Cyclicality and Demand Fluctuations: The company's business is significantly tied to volatile end-markets such as paper, steel, and foundry, which experience fluctuations aligned with industrial cycles. There is also a risk from the secular decline in demand for graphic paper, which impacts sales of Precipitated Calcium Carbonate (PCC). Lower volumes in these end-markets can directly reduce sales of PCC and refractory products.
3. Raw Material and Energy Cost Volatility: Minerals Technologies is exposed to swings in the costs of key raw materials like bentonite, soda ash, natural gas, refractory-grade magnesia, and alumina silicates, as well as energy prices. These fluctuations can materially impact input costs and gross margins. Geopolitical events and supply-chain disruptions can exacerbate these cost pressures, potentially compressing margins and delaying revenue.
