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

What stands out

Karl Jorgenrud sold 46% of vested holdings: 7.9K shares for $2.9M, none under a disclosed plan.Largest sale, Aug 7, 2026

Two officers sold $5.8M with no disclosed plan: Justin Binns ($4.8M) and Colin Davie ($1.1M). The filings don't state a reason.Justin Binns: largest such sale, Aug 17, 2026 · Colin Davie: largest such sale, Feb 2, 2026

Bryan Young sold 2.5K shares (24% of starting holdings), but 4K more vested, so the stake grew (from 11K to 11K).Largest sale, Feb 24, 2026

Percentages cover 18 of 20 officers and directors. Left out: Justin Binns and Colin Davie (most of their shares vested during the period, so a percentage would mislead). 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 Sherwin-Williams CEO selling stock?

No. Heidi Petz reported no open-market sales in the past 12 months.

Why are Sherwin-Williams insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 100% had no disclosed plan. A trading plan schedules sales in advance.

Are any Sherwin-Williams insiders buying?

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

How much of their stake did Sherwin-Williams insiders sell?

About 4.6% overall. As a group they ended with more shares than they started with. The biggest seller whose stake can be measured, Karl Jorgenrud, gave up 46% of starting holdings. 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.

Estimate: options held × ($352.70 − strike price), using the most recent insider trade price on Form 4 (Aug 17, 2026), not a market close.

20 of 20 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (6 exactly, 14 with a minor or footnoted difference). Percentages cover 18 of 20 officers and directors. Left out: Justin Binns and Colin Davie (most of their shares vested during the period, so a percentage would mislead). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$9.7M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $9.7M across 26,875 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $9.7M

Sales with no 10b5-1 plan and no tax reference in the filing. $4.8M of it is Justin Binns. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Justin Binns, Aug 17, 2026

Taxes

32,979 shares ($12.2M) were withheld by the company for taxes, which isn't a market sale.

Charitable gifts · 813 shares

Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

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.

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

Sources and methodology2,205 filings from SEC EDGAR, and how we read them

All 2,205 Forms 3, 4 and 5 filed for Sherwin-Williams (SEC CIK 89800) from Mar 3, 2003 to Oct 6, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 67 older filings exist only on paper and could not be read.

Probable 3-for-1 stock split on or before Mar 31, 2021 (split date stated in a footnote). Splits aren't reported as transactions; 17 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".
