1. Think of them as the Corning (known for Gorilla Glass) of industrial minerals, providing critical engineered ingredients for a wide range of manufactured products.

2. They are like the 3M of specialty industrial minerals, supplying innovative mineral-based solutions across diverse sectors globally.

• Precipitated Calcium Carbonate (PCC): A synthetic mineral used to enhance the whiteness, brightness, and opacity of paper, and as a filler and extender in plastics, paints, and coatings.
• Processed Minerals: A range of minerals including talc, bentonite, and ground calcium carbonate, used in various industries like automotive, ceramics, and construction.
• Refractory Materials: High-temperature resistant materials, such as monolithics and pre-cast shapes, essential for the global steel industry and other high-temperature processes.
• Metal Casting Products: Specialized materials and solutions for foundries to improve casting quality and performance.

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.

Minerals Technologies (MTX) is poised for future revenue growth over the next 2-3 years, driven by strategic investments, expansion in high-growth markets, and a focus on specialized product offerings. Key drivers include:

1. Capacity Expansions and Strategic Investments in High-Growth Areas: Minerals Technologies is making significant investments in new capacity and plant expansions across various segments, which are expected to generate approximately $100 million in incremental revenue over the next 12 to 18 months. These investments are targeted at supporting demand in areas such as sustainable aviation fuel, animal health, fabric care, and pet care, with new facilities and upgrades in locations like Dyersburg, Tennessee; Branford, Ontario; and Chaoyang City, China.
2. Growth in Household & Personal Care (HPC), particularly Pet Care: The company anticipates continued revenue growth from its Household & Personal Care segment, especially within the pet care market. Minerals Technologies is strengthening its position as a leading private label cat litter supplier globally, with new contracts secured to commence in 2026. Other consumer specialties, such as higher-tech fabric care solutions for dry laundry detergent, are also contributing to this growth.
3. Expansion in Renewable Fuels and Edible Oil Purification: A significant driver is the company's focus on the rapidly expanding market for edible oil and renewable fuel purification, which includes biodiesel, renewable diesel, and sustainable aviation fuel (SAF). The global natural oil purification market is substantial, with the renewable fuels portion being the fastest-growing segment, particularly SAF, which is being bolstered by supportive regulatory changes in the U.S. and Europe. Minerals Technologies' Rafinol product line is specifically highlighted for its high-performing absorptive properties crucial for demanding applications like SAF.
4. Increased Demand in Asia and Environmental & Infrastructure Services: The company has observed strong demand across Asia, with foundry volumes showing significant year-over-year increases. Additionally, its environmental and infrastructure product line is experiencing increased demand for offshore services and infrastructure drilling products, further contributing to revenue growth.
