LOY BERTRAND 4

What Happened

• Loy Bertrand, Executive Chair and Director of Entegris (ENTG), exercised 9,838 stock options on Feb 24, 2026 at $98.11 per share (total exercise cost ≈ $965,206) and completed multiple open‑market sales on Feb 24–25, 2026.
• The open‑market sales totaled about 109,838 shares across several trades at weighted average prices between roughly $137 and $142, generating aggregate proceeds of about $15.2 million.
• These actions are sales (routine monetization/liquidity) combined with an option exercise; the filing shows both the exercise and same‑day sales (i.e., shares were sold after exercise).

Key Details

• Transaction dates: Feb 24 and Feb 25, 2026 (Form 4 filed Feb 26, 2026). Filing appears timely.
• Option exercise: 9,838 shares exercised at $98.11 (footnote indicates option fully vested).
• Sales: ~109,838 shares sold in multiple trades; reported proceeds ≈ $15,185,007. Reported weighted average prices per groups ranged roughly from $137.05 to $142.09 (see filing footnotes for exact ranges).
• Footnotes: some sales were executed under a Rule 10b5‑1 trading plan (established Feb 10, 2025). Several sale lines report weighted average prices and provide price ranges for the multiple transactions.
• Shares owned after the transactions: not specified in the provided excerpt of the filing.

Context

• The filing shows an option exercise followed by share sales the same days; this pattern is commonly used to cover exercise costs and/or to monetize equity, but the filing itself does not state a motive.
• Sales executed under a Rule 10b5‑1 plan are pre‑planned trades and are generally viewed as scheduled rather than based on contemporaneous inside information.
• For retail investors: purchases (insider buys) can be more informative of confidence than routine sales; Bertrand’s activity here is primarily a large, scheduled/market sale plus an exercise.
