Minerals Technologies Inc.
A global specialty minerals company that digs up and transforms minerals like bentonite and calcium carbonate into everyday products — from clumping cat litter to paper coatings and construction sealants. It began in 1992 as a spin-off from the drugmaker Pfizer, which had quietly built a minerals division decades earlier. Bentonite, its signature clay formed from ancient volcanic ash, is sometimes called the "mineral of 1,000 uses."

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last year: -57.2K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
