Details

Common questions

Is the Entegris Inc CEO selling stock?

No. David Reeder reported no open-market sales in the past 12 months.

Why are Entegris Inc insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 78% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 22% had no disclosed plan. A trading plan schedules sales in advance.

Are any Entegris Inc insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

What explains the selling$51.1M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $51.1M across 405,562 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $40.1M · 78%

22%

The lighter segment is sales with no plan disclosed in the filing ($11.0M), including tax-related sales outside a plan.

No plan disclosed · $11.0M

Sales with no 10b5-1 plan and no tax reference in the filing. $4.0M of it is Daniel Woodland. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Susan Rice, May 15, 2026

Taxes

59,297 shares ($7.7M) were withheld by the company for taxes, which isn't a market sale.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertainty17 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Entegris Inc are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology1,710 filings on record, 64 filed in the 12-month period, and how we read them

All 1,710 Forms 3, 4 and 5 on record for Entegris Inc (SEC CIK 1101302), filed from Oct 16, 2002 to Aug 19, 2026; 64 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 2026. Prices are the ones reported in each filing, often weighted averages. 16 filings were left out because Entegris Inc filed them as an owner of another company's stock. 56 older filings exist only on paper and could not be read.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
