What stands out

Padraig McDonnell sold 40% of vested holdings: 13K shares for $2.0M, all under a disclosed plan.Largest sale, Nov 12, 2025

Percentages cover 21 of 24 officers and directors. Left out: Rodney Gonsalves and Angelica Riemann (holdings couldn't be fully reconciled); Adam Elinoff (held no vested shares at the start). Disclosed company stock is not an insider's whole wealth.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is the insider's vested stake at the start of the period (Oct 8, 2025). The gold part is what they sold.

Common questions

Is the Agilent Technologies CEO selling stock?

Yes. Padraig McDonnell sold 13K shares ($2.0M, 40% of starting holdings) in the past 12 months, all of it under a trading plan disclosed in the filings.

Why are Agilent Technologies insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 63% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 37% had no disclosed plan. A trading plan schedules sales in advance.

Are any Agilent Technologies insiders buying?

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

How much of their stake did Agilent Technologies insiders sell?

About 3.4% overall. As a group they ended with more shares than they started with. The biggest individual seller, Padraig McDonnell, sold shares equal to 40% of starting holdings, but more vested, so the stake grew. That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

22 of 24 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (14 exactly, 8 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 21 of 24 officers and directors. Left out: Rodney Gonsalves and Angelica Riemann (holdings couldn't be fully reconciled); Adam Elinoff (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$3.2M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $3.2M across 21,235 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $2.0M · 63%

37%

The lighter segment is sales with no plan disclosed in the filing ($1.2M), including tax-related sales outside a plan.

No plan disclosed · $1.2M

Sales with no 10b5-1 plan and no tax reference in the filing. $702K of it is Mikael Dolsten. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Rodney Gonsalves, Nov 26, 2025

Taxes

14,306 shares ($2.0M) were withheld by the company for taxes, which isn't a market sale.

Less than usual: about one-ninth of the 5-year average. 3 insiders sold; the average is 7 a year.

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 uncertainty2 insiders whose holdings couldn't be fully reconciled

Rodney Gonsalves: holdings couldn't be fully reconciled (difference of 756 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +626.6674 shares on Nov 26, 2025 (Direct). Filing, Nov 26, 2025

Sources and methodology1,568 filings from SEC EDGAR, and how we read them

All 1,568 Forms 3, 4 and 5 filed for Agilent Technologies (SEC CIK 1090872) from Sep 11, 2000 to Sep 10, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 3 filings were left out because Agilent Technologies filed them as an owner of another company's stock. 103 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".
