Insights

Financial Analyst

TL;DR: Routine insider notice disclosing a small proposed sale of Entegris shares; not clearly material to valuation.

The Form 144 lists a proposed disposition of 4,547 common shares valued at $435,557.13 scheduled for 09/18/2025 through Fidelity Brokerage Services LLC. The filing identifies the provenance of the shares: 1,772 from an option (granted 01/31/2023) sold for cash and 2,267 and 508 from restricted stock vesting (02/19/2025 and 04/05/2025) recorded as compensation. No sales in the prior three months are reported. For investors, this is a transparent disclosure of a planned insider sale; the absolute size relative to total outstanding shares (151.6 million reported) suggests limited direct impact on broad market valuation based solely on this notice.

Corporate Governance Expert

TL;DR: Standard Rule 144 filing documenting a proposed sale from option exercise and vested restricted stock; governance controls appear followed.

The document provides required specifics: broker name and address, number of shares, aggregate market value, acquisition dates and nature (option exercise and restricted stock vesting), and the filers attestation regarding material nonpublic information. The filing indicates use of a brokerage firm and includes the statutory signature/attestation language, which aligns with routine insider compliance practices. No additional governance issues or anomalies are disclosed in this notice.
