ROBINSON MARC E 4

What Happened
Marc E. Robinson, a director of Minerals Technologies Inc. (MTX), was granted 44.39 phantom stock units on March 6, 2026. The units were reported as an award (transaction code A) at a $0.00 acquisition price and are recorded as a derivative award rather than an open-market purchase. The filing does not state a cash value for the grant.

Key Details

• Transaction date: 2026-03-06; Form 4 filed: 2026-03-10 (timely filing).
• Instrument: 44.39 phantom stock units (derivative award), acquisition price reported as $0.00.
• Shares owned after transaction: not disclosed in the filing.
• Footnotes: The units are economic equivalents of one share each and were accrued under the company’s Non‑Funded Deferred Compensation and Unit Award Plan for Non‑Employee Directors; they are to be settled in cash upon the director’s termination of service.
• Transaction type: Award/Grant (A) — routine director compensation, not a purchase or sale.

Context
Grants of phantom stock units to non-employee directors are common as part of deferred compensation and are typically cash‑settled upon departure; they do not represent an immediate open‑market buy or sale and therefore should not be read as a direct bullish or bearish trading signal. The award increases the director’s economic exposure to the company’s stock performance, but no immediate share issuance or cash value was reported.
