Haris Clinton M. 4

What Happened
Haris Clinton, SVP and President of the APS Division at Entegris, had 1,290 restricted stock units (RSUs) automatically withheld to satisfy tax withholding obligations upon vesting. The shares were valued at $116.40 each, for a total withholding value of $150,156. This was a tax-withholding disposition (transaction code F), not an open-market sale.

Key Details

• Transaction date: 2026-04-05 (vesting/settlement); Form 4 filed 2026-04-06 (timely).
• Price used per share: $116.40 (closing price on April 2, 2026, the last trading day before the April 5 vesting).
• Shares withheld/disposed: 1,290; aggregate value: $150,156.
• Shares owned after transaction: not specified in the filing.
• Footnotes: F1 — shares automatically withheld to satisfy tax withholding on RSU settlement; F2 — price reflects the last trading day (Apr 2) because vesting occurred on Sunday (Apr 5).
• Transaction code: F (payment of tax liability via share withholding).

Context
Withholding shares to cover taxes on vested RSUs is a routine administrative action and does not necessarily signal a change in the insider’s view of the company. This was not a market sale or a purchase; rather, a portion of the vested award was retained by the company/broker to pay required taxes.
