PNR insider ownership: who sold, why, and what they still hold

Who	Shares	Price	% of total stake	Total stake after	Trade date	Filed
Robert Fishman Interim EVP and CFO	1,820	$59.84	n/a	n/a	Sep 2, 2026	Sep 4, 2026

What stands out

Tax withholding outweighed market sales: the company withheld $8.4M of officers' and directors' shares for taxes, against $2.9M sold on the open market. The largest was Robert Fishman ($2.2M withheld).Largest withholding, Feb 23, 2026

Michael Glenn sold 6.6K shares (11% of starting holdings), but 9.5K more shares were added, so the stake grew (from 61K to 63K).Largest sale, Dec 1, 2025

Percentages cover 4 of 22 officers and directors. 18 are left out

Left out: John Stauch, Robert Fishman, Jerome Pedretti, Philip Rolchigo, Stephen Pilla, Adrian Chiu, Billie Williamson, DeMon Wiggins, Theodore Harris, Mona Stephenson, Tanya Hooper, Gregory Knight, Melissa Barra, Tracey Doi, Jennifer Hensley, Heather Hausmann and Nicholas Brazis (holdings couldn't be fully reconciled); Michael Speetzen (most holdings were last confirmed in 2023).

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 100% of that person's own stake; not comparable between people. The stake is the vested shares held at the start of the period (Oct 9, 2025); the gold part is what they sold.

Common questions

Is the Pentair CEO selling stock?

No. John Stauch reported no open-market sales in the past 12 months.

Why are Pentair insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 47% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 53% had no disclosed plan. A trading plan schedules sales in advance.

Are any Pentair insiders buying?

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

How much of their stake did Pentair insiders sell?

About 5.8% overall. As a group they ended with more shares than they started with. These figures leave out John Stauch, the largest holder (holdings couldn't be fully reconciled). That covers the 12 months to Oct 9, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

5 of 22 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (2 exactly, 3 with a minor or footnoted difference). For 17 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 4 of 22 officers and directors. Left out: John Stauch, Robert Fishman, Jerome Pedretti, Philip Rolchigo, Stephen Pilla, Adrian Chiu, Billie Williamson, DeMon Wiggins, Theodore Harris, Mona Stephenson, Tanya Hooper, Gregory Knight, Melissa Barra, Tracey Doi, Jennifer Hensley, Heather Hausmann and Nicholas Brazis (holdings couldn't be fully reconciled); Michael Speetzen (most holdings were last confirmed in 2023). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$2.9M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $2.9M across 27,837 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $1.4M · 47%

53%

The lighter segment is sales with no plan disclosed in the filing ($1.5M), including tax-related sales outside a plan.

No plan disclosed · $1.5M

Sales with no 10b5-1 plan and no tax reference in the filing. $821K of it is Robert Fishman. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Michael Speetzen, Feb 11, 2026

Taxes

82,809 shares ($8.4M) were withheld by the company for taxes, which isn't a market sale.

Is this normal? Selling year by year5 earlier years to compare with

In line with the past 5 years. 4 insiders sold; the average is 3 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.

Sources and methodology2,345 filings from SEC EDGAR, and how we read them

All 2,345 Forms 3, 4 and 5 filed for Pentair (SEC CIK 77360) from Jan 6, 2003 to Sep 28, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 74 older filings exist only on paper and could not be read.

Probable 2-for-1 stock split on or before May 17, 2004 (split date stated in a footnote). Splits aren't reported as transactions; 15 holding lines changed by exactly this ratio, so earlier share counts are restated.

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".
