[Form 4] Entegris Inc Insider Trading Activity

Rhea-AI Filing Summary

On 17 Jul 2025, Entegris Inc. (ENTG) Senior Vice President & President, APS Division, Clint M. Haris filed a Form 4 disclosing the sale of 3,627 common shares of company stock at an indicated price of $90.00 per share. The transaction was executed under a pre-arranged Rule 10b5-1 trading plan adopted on 10 Feb 2025, signalling it was scheduled in advance rather than timed to near-term news. After the sale, Haris retains 37,742.67 shares held directly, a position that still reflects meaningful insider ownership; this total includes 257.12 shares acquired through the Employee Stock Purchase Plan on 30 Jun 2025. The filing, signed 21 Jul 2025, represents routine insider activity and does not announce any changes to management roles, strategy or guidance.

Insights

Portfolio Manager

TL;DR: Small, pre-planned sale; neutral signal, minimal portfolio impact.

The 3,627-share sale (≈US$326k) by SVP Clint Haris equates to a fraction of both his personal holdings and Entegris’ total float, and it was executed under a Rule 10b5-1 plan. Such pre-scheduled trades typically mitigate concerns about information asymmetry. Haris still holds roughly 37.7k shares, maintaining aligned incentives. Given the modest size relative to ENTG’s US$15bn+ market cap, I view the event as immaterial; it should not influence valuation models or risk assessments.
