After the March 6, 2026 award, Carolyn K. Pittman holds 18,608.883 phantom stock units. This reflects the addition of 33.087 new units granted under the Non-Funded Deferred Compensation and Unit Award Plan for Non-Employee Directors at Minerals Technologies Inc.

Is the Minerals Technologies (MTX) Form 4 transaction a stock purchase or sale?

The Form 4 shows a grant of derivative phantom stock units, not a market purchase or sale of common shares. The transaction is recorded with code "A" for an award, and the units will be paid in cash upon termination of the director’s service.

When will the phantom stock units for the Minerals Technologies (MTX) director be settled?

The phantom stock units will be settled in cash when Carolyn K. Pittman’s service as a director ends. Until that time, they function as deferred compensation whose value mirrors Minerals Technologies’ common stock performance under the non-employee director plan.
