DIETRICH DOUGLAS T 4

What Happened
Douglas T. Dietrich, Chairman and CEO of Minerals Technologies Inc. (MTX), received two derivative equity awards on January 20, 2026 totaling 72,494 units. The filings show awards of 39,000 and 33,494 derivative units at $0.00 per unit (grant value recorded as $0 in the Form 4). These awards are grants (not open‑market purchases or sales) and do not reflect an immediate cash transaction or sale.

Key Details

• Transaction date: January 20, 2026; Form 4 filed January 22, 2026 (appears timely).
• Awarded units: 39,000 and 33,494 derivative units (total 72,494).
• Reported price: $0.00 per unit (standard for grants/awards at issuance).
• Footnotes: DRSUs are economically equivalent to one share each; DRSUs and options were granted Jan 20, 2026 and vest in three equal annual installments beginning Jan 20, 2027. (One award group are DRSUs; the other are stock options.)
• Shares owned after the transaction: not specified in the provided excerpt of the filing.
• Transaction code: A = Award/Grant (derivative instruments). No exercise or sale occurred.

Context
These are time‑based equity awards that vest over three years (one third per year starting Jan 20, 2027). DRSUs convert to the economic equivalent of shares when vested (usually delivered as shares or settled in cash per company plan), while the stock options provide the right to buy shares in the future subject to vesting and plan terms. Because these are grants rather than purchases or sales, they reflect compensation/retention arrangements rather than an immediate insider buy/sell signal.
