LOY BERTRAND 4

What Happened

• Loy Bertrand, Executive Chair and Director of Entegris (ENTG), exercised stock options to acquire 65,250 shares at a strike price of $55.72 (cash outlay ≈ $3,635,730) on Feb 2, 2026. On the same date he sold a total of 65,250 shares in a series of open-market transactions that together brought in roughly $7.80 million.
• Sales were executed in multiple tranches with weighted-average prices and proceeds reported as:
  • 200 shares @ $115.96 = $23,192
  • 2,412 shares @ $117.19 = $282,662
  • 9,292 shares @ $118.43 = $1,100,452
  • 16,424 shares @ $119.13 = $1,956,591
  • 34,522 shares @ $120.25 = $4,151,271
  • 2,400 shares @ $120.91 = $290,184
• The filing also includes a derivative disposition entry for 65,250 shares reported as N/A (reflecting the option exercise/conversion).

• Sales: 65,250 shares sold in open market under a Rule 10b5-1 trading plan established Feb 10, 2025 (F2). Prices shown are weighted averages for grouped trades (see footnotes F3–F8 for per-range details).

• Shares owned after transaction: Not specified in the provided filing excerpt.

Context

• This was an option exercise paired with immediate/open-market sales (a routine cash-raising or tax-liability management move rather than an open-market purchase). Sales executed under a 10b5-1 plan are prearranged and do not necessarily signal a change in insider sentiment.
• For retail investors: purchases by insiders often attract more attention as potential bullish signals; exercises followed by sales are commonly liquidity-driven. The filing is factual — it does not explain Bertrand’s motive.
