CIPOLLA MICHAEL 4

What Happened
Michael Cipolla, Vice President of Minerals Technologies Inc. (MTX), was granted two derivative awards on January 20, 2026: 4,618 units and 3,966 units (total 8,584). Both grants show an acquisition price of $0.00 because these are compensation awards (DRSUs and option units per the filing footnotes) rather than open-market purchases. The awards vest in three equal annual installments beginning January 20, 2027.

Context
DRSUs represent the economic value of shares but typically convert to shares or cash only upon vesting (and may be subject to tax withholding). The option units will require exercise according to their terms to result in actual shares. Because these are compensation grants, they reflect company pay practices rather than an immediate buy/sell signal by the insider.
