Rhea-AI Filing Summary

PITTMAN CAROLYN K reported acquisition or exercise transactions in this Form 4 filing.

Minerals Technologies Inc. director Carolyn K. Pittman received a grant of 33.087 phantom stock units on March 6, 2026. These units are derivatives whose value matches one share of common stock each and increase her deferred phantom balance to 18,608.883 units.
