CARMOLA JOHN J 4

What Happened

• John J. Carmola, a director of Minerals Technologies Inc. (MTX), was granted 1,908.146 phantom stock units on 2026-05-20. The units are recorded at $0.00 per unit for securities reporting purposes and represent a cash‑settled derivative award, not an immediate share purchase or sale. The reported transaction value is $0 in equity terms on the Form 4 because these are phantom units (deferred compensation).

Key Details

• Reported price/value: $0.00 per unit on the filing; no immediate stock purchase or sale proceeds.
• Shares/units owned after transaction: not disclosed in this filing.
• Footnotes:
  • F1: Each phantom stock unit equals the economic equivalent of one share of MTX common stock.
  • F2: Units were granted under the Minerals Technologies Inc. Non‑Funded Deferred Compensation and Unit Award Plan for Non‑Employee Directors and will be settled in cash upon the director’s termination of service.

Context

• These phantom units are a form of deferred compensation tied to MTX share value but do not transfer actual shares to the director now; payout will be in cash when Carmola leaves the board per the plan terms. Such awards are common for non‑employee directors and are routine compensation rather than direct buy/sell signals for investors.
