CARMOLA JOHN J 4

What Happened
John J. Carmola, a director of Minerals Technologies Inc. (MTX), was granted 46.236 phantom stock units on March 6, 2026. The units were reported at $0.00 per unit (no cash paid) and are derivative awards that represent the economic equivalent of common shares; they will be settled in cash when he ceases service as a director. This is an award/compensation transaction (not an open‑market purchase or sale) and is commonly used for non‑employee director pay.
