Minerals Technologies Inc. (NYSE: MTX) held its 2026 Investor Day on September 22 at its research and development facilities in Bethlehem, Pennsylvania, where the company reiterated its long-term financial targets and presented two new revenue growth initiatives.

The company disclosed plans to produce high-purity calcium metal to support domestic heavy rare earth metallization. Minerals Technologies already manufactures calcium metal in the United States for use in high-strength steel production. The company said it has developed a new process to manufacture a higher-purity version of the material, targeting supply chains serving the aerospace and defense, transportation, renewable energy, electronics, and medical technology sectors. The company estimates the opportunity could generate more than $100 million in incremental revenue over the next several years.

Minerals Technologies also announced an expansion of its Crystal Engineering technology, which underpins its NewYield® product that repurposes pulp waste from paper mills. The company said the technology can now be applied to steel slag. According to the press release, three million tons of steel slag are landfilled annually in the United States. The company's process would convert that material into mineral products including magnesium and manganese. Minerals Technologies estimates the total addressable market for this application exceeds $250 million in the U.S. alone.

Chairman and Chief Executive Officer Douglas T. Dietrich said the company's growth strategy centers on applying its core technologies to higher-value markets, citing additional initiatives including automation for steelmaking, PFAS remediation, Sustainable Aviation Fuel filtration, and waste repurposing in paper and packaging.

Minerals Technologies reported global sales of $2.1 billion in 2025 and employs approximately 4,000 people across 34 countries.
