JORDAN TIMOTHY 4

What Happened
Jordan Timothy, Vice President of Minerals Technologies Inc. (MTX), had 1,897 deferred restricted stock units (DRSUs) vest/convert on January 21, 2026. The conversion is reported as an exercise/conversion of a derivative (code M) at $0 exercise price. To satisfy tax withholding obligations (code F), 1,071 of the resulting shares were withheld at an implied per-share value of $66.92, totaling $71,671. The transaction reflects a routine settlement of vested awards rather than an open-market purchase or active sale for investment purposes.

Key Details

• Transaction date: January 21, 2026; Form 4 filed January 23, 2026 (appears timely).
• Conversion: 1,897 DRSUs converted to common shares (reported at $0 exercise price).
• Tax withholding: 1,071 shares withheld @ $66.92 per share = $71,671 (reported as disposed to company).
• Additional reported derivative entry: 1,897 shares listed as a derivative disposition at $0 — this reflects the accounting/reporting of the vested DRSUs and net settlement mechanics.
• Shares owned after the transaction: not disclosed in this Form 4.
• Footnotes: the shares withheld were to satisfy tax obligations (F1); the report is based on a Plan Statement dated Jan 21, 2026 (F2); each DRSU equals one share economically (F3); the DRSUs were granted Jan 21, 2025 and vest in three equal annual installments starting Jan 21, 2026 (F4).

Context
DRSUs are equity awards that convert into company shares when they vest; this filing shows a typical vest-and-net-settle event where a portion of shares is withheld to cover taxes. Such withholding is routine and should not be interpreted as a discretionary sale by the insider. For retail investors, purchases or outright open-market sales by insiders often carry stronger signals than tax-withholding settlements of vested awards.
