ENTG ENTEGRIS INC Insider Trading

SVP Clinton M. Haris sold 6,848 shares of ENTG at $149.23 (scheduled 10b5-1 trade); retains 54,960 shares post-transaction.

Clinton M. Haris, SVP & President of the APS Division, sold 6,848 shares at $149.23 for a total value of $1,021,927.04 on 2026-05-27 under a pre-arranged 10b5-1 trading plan, reducing his non-derivative holdings from 61,808 shares to 54,960 shares. This transaction occurs with ENTG trading at $139.92, down 12.1% from its 52-week high of $159.15. Across his five prior trades at ENTG, Haris has seen mixed outcomes: a recent sell on 2026-05-14 saw a 30-day return of -3.2%, while a 2026-01-21 sale followed by a 90-day return of +22.5%. The scheduled nature of this sale under a 10b5-1 plan means it reflects contractual execution rather than a discretionary decision in response to current market conditions. ENTG's fundamentals show revenue of $811,900,000.00 (latest quarter), net income of $92,000,000.00, and a P/E of 80.41, suggesting the valuation context that may have motivated the pre-plan arrangement.

SVP Rice sells 19,893 shares ($2.6M) at $132.84 avg; stock off 20.1% from 52-week high of $159.15

Rice Susan G., SVP of Global Human Resources, executed 2 separate sales totaling 19,893 shares for $2,642,598.33 on 2026-05-15 at a blended average price of $132.84, reducing her holdings from 88,931 shares to 69,038 shares. The transaction occurred as the stock trades at $127.12, down 20.1% from its 52-week high of $159.15 and down 13.0% over the prior 30 days. Her prior trades at ENTG consist of 2 sales on 2024-02-16, outcomes not yet measurable. The company shows a P/E of 73.06 against net income of $92,000,000.00 on quarterly revenue of $811,900,000.00, with annual revenue growth of -1.4%.

SVP General Counsel Joseph Colella sold 6,326 shares for $886,715.40 at $140.17 avg; stock down -20.1% from 52-week high

Joseph Colella executed 2 separate sales totaling 6,326 shares for $886,715.40 on 2026-05-14, reducing his holdings from 56,447 to 50,121 shares. The transactions occurred at prices of $140.25 and $140.04, substantially above the current price of $127.12, indicating the sales occurred during a period of relative strength. Against the broader context, the stock is -20.1% from its 52-week high of $159.15 and has declined -13.0% over the past 30 days, suggesting recent momentum weakness. The P/E of 73.06 and trailing revenue decline of -1.4% indicate the company is trading at elevated valuation multiples amid softening top-line growth, a backdrop in which insider selling may be notable.

SVP & President Haris Clinton M. sold 5,830 shares of ENTG at $144.57 on 2026-05-14 under 10b5-1 plan; current price $127.12.

Haris Clinton M., SVP & President of the APS Division, executed a scheduled sale of 5,830 shares valued at $842,843.10 under a pre-arranged 10b5-1 trading plan, reducing his holding from 60,790 to 54,960 shares. The transaction occurred at $144.57, which was above the current price of $127.12 (a -20.1% decline from the 52-week high of $159.15). Reviewing his prior trades at ENTG, his sales have shown mixed outcomes: the most recent sale on 2026-01-21 saw 90-day gains of +22.5%, while the 2025-02-10 sale experienced 90-day losses of -28.6%, indicating volatility in post-sale price movement at this ticker. As a 10b5-1 plan execution, this sale is scheduled rather than discretionary, so it does not reflect timing judgment or updated conviction.

Executive Chair Loy Bertrand sells 44.1K ENTG shares at $144.41; stock up 29.9% in 30 days.

Loy Bertrand, Executive Chair of Entegris, sold 44,138 shares at $144.41 on 2026-04-17, reducing his holdings by 16.2% from 271,665 to 227,527 shares. The sale occurred as ENTG stock is trading near its 52-week high of $148.92, with a 30-day gain of 29.9% and a 90-day gain of 29.5%, suggesting the executive sold into a period of strong momentum. However, his same-ticker selling history at ENTG shows five prior sells with measurable 30-day outcomes, all of which were poorly timed (30-day returns of -17.3%, -18.0%, -16.5%, and -17.6%), indicating he has not successfully caught downturns at this specific stock. His cross-ticker track record of 20 prior open-market sales shows an average 90-day return of +24.8% with a well-timed rate of 50.00%, but the lack of measurable 90-day outcomes from his ENTG sales limits confidence in whether this sale will prove strategic at this ticker.

Bertrand (Executive Chair) sells 17,396 ENTG shares at $140.22 for $2.4M; holdings down to 227.5K

Loy Bertrand, Executive Chair of Entegris, sold 17,396 shares on 2026-04-14 at $140.22, reducing holdings by 7.1% to 227.5K shares. His recent trading history at ENTG shows five consecutive sales in late February—all of which declined 17.3% to 18.6% within 30 days—establishing a clear pattern of poorly timed exits at this ticker. His cross-ticker track record (19 prior sales with 50% well-timed rate and +24.8% average 90-day return) suggests his sells have generally missed subsequent gains across his portfolio. The current price of $135.92 sits near the 52-week high of $138.07 (-1.6%), with stock momentum strong at +17.1% over 30 days, leaving limited upside cushion. The company's stretched valuation (P/E 89.42) and flat annual revenue growth (-1.4%) provide no fundamental tailwinds to support further appreciation from current levels.

Executive Chair LOY BERTRAND sold 109,838 shares for $15.2M across 7 transactions; scheduled 10b5-1 plan.

LOY BERTRAND, Executive Chair, executed 7 separate sales totaling 109,838 shares for $15,185,007.99 on 2026-02-24 and 2026-02-25 at prices ranging from $137.32 to $142.19 (blended average $138.25). The transaction is part of a pre-arranged 10b5-1 trading plan, meaning the sales were scheduled in advance rather than discretionary. Post-transaction holdings of 217,767 shares represent a 33.5% reduction from pre-transaction levels of 327,605 shares. As a scheduled plan-based execution, this sale reflects a pre-determined strategy rather than a contemporaneous market judgment.

CFO LaGorga sells 11,438 shares of ENTG at $135.00; holdings cut to 33,810 shares (-25.3% vs pre-transaction)

Linda LaGorga, Chief Financial Officer, sold 11,438 shares at $135.00, reducing her stake from 45,248 to 33,810 shares—a 25.3% reduction in holdings. The sale occurred near the stock's 52-week high of $137.79 and follows a sharp 90-day gain of 85.0%, paired with 30-day momentum of +18.9%. Against this backdrop, the company's fundamentals show modest headwinds: annual revenue contracted 1.4% year-over-year, and a P/E of 89.75 suggests elevated valuation expectations. The timing and magnitude of the reduction warrant scrutiny given the stock's recent price momentum and the CFO's material shrinkage of equity exposure.

SVP Daniel Woodland sells 30,474 shares at blended average $130.65; cuts ENTG stake -39.4% to 46,903 shares

Daniel Woodland, SVP & President of the MS Division, executed 3 separate sales totaling 30,474 shares (30.5K shares) for $3,981,313.40 ($4.0M) at prices ranging from $130.52 to $130.80 on February 12, 2026. This transaction reduces his post-transaction holdings to 46,903 shares (46.9K shares), representing a -39.4% reduction versus pre-transaction holdings of 77,377 shares (77.4K shares). Notably, his prior 3 measurable same-ticker sales at ENTG all posted negative 90-day returns (-28.3%, -28.3%, -27.0%), achieving a 100% well-timed rate at this ticker; his cross-ticker track record also shows a 100.00% well-timed rate across 4 prior sells with avg 90d return of -23.3%. However, the 30-day and 90-day forward windows from this transaction cannot yet be assessed. The current stock price of $129.56 sits -6.0% from the 52-week high of $137.79; the blended sale price of $130.65 is slightly above current levels, and the stock has rallied +10.4% over the past 30 days and +75.6% over 90 days—making near-term timing assessment premature.

Executive Chair LOY BERTRAND sold 65,250 shares for $7,804,351.46 via 6 sales on 2026-02-02 under 10b5-1 plan

LOY BERTRAND executed 6 separate sales totaling 65,250 shares for $7,804,351.46 on 2026-02-02 at blended average price of $119.61, reducing holdings by 17.6% to 306,422 shares post-transaction. This activity is part of a pre-arranged 10b5-1 trading plan, meaning it is scheduled and not discretionary. The multiple tranches at different price points ($115.96 to $120.91) reflect execution across a trading window rather than a single deliberate decision point. As a scheduled disposition under an established plan, this filing does not reflect real-time conviction or concern, but rather the mechanical execution of a plan likely adopted months prior.
