ARGIRAKIS BRETT 4

What Happened
Brett Argirakis, Group President of Minerals Technologies Inc. (MTX), received equity awards on January 20, 2026: 12,101 deferred restricted stock units (DRSUs) and 10,393 stock options. Both awards were granted at $0.00 (typical for compensation grants) and therefore involved no cash paid by the insider. Together the awards represent economic exposure to 22,494 shares (12,101 DRSUs + 10,393 option shares), though the options are not shares until exercised.

Context
DRSUs typically convert to shares (or equivalent cash) upon vesting and reflect long-term compensation; stock options require exercise to become shares. These awards are compensation grants rather than open-market purchases or sales, so they are routine executive pay actions and not a direct buy/sell signal.
