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

Anurag Maheshwari EVP & Chief Financial Officer	4,991	$163.02	29%	12K	Oct 1, 2026	Oct 2, 2026

What stands out

Five officers sold $19.3M with no disclosed plan: Zoe Dickson ($12.4M), Mark Murphy ($3.2M) and John Banovetz ($1.3M), plus 2 more. The filings don't state a reason.Zoe Dickson: largest such sale, Feb 9, 2026 · Mark Murphy: largest such sale, Oct 29, 2025 · John Banovetz: largest such sale, Jul 23, 2026

Percentages cover 15 of 29 officers and directors. 14 are left out

Left out: John Banovetz, Mark Murphy, Zoe Dickson, Theresa Reinseth, Christian Goralski Jr., Rodriguez Chavez, David Bozeman and Victoria Clarke (holdings couldn't be fully reconciled); Jonathan Van Wyck, Torsten Pilz, Paul Gallagher, Neil Mitchill Jr., Jennifer Rumsey and Jennifer Cunningham (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 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 3M CEO selling stock?

No. William Brown reported no open-market sales in the past 12 months.

Why are 3M 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 3M insiders buying?

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

How much of their stake did 3M insiders sell?

About 3.9% of the shares they held or received (after tax withholding) during the period. The usual measure, against starting holdings alone, can't be used here because most of the shares sold arrived during the period. 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.

21 of 29 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (13 exactly, 8 with a minor or footnoted difference). For 8 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 15 of 29 officers and directors. Left out: John Banovetz, Mark Murphy, Zoe Dickson, Theresa Reinseth, Christian Goralski Jr., Rodriguez Chavez, David Bozeman and Victoria Clarke (holdings couldn't be fully reconciled); Jonathan Van Wyck, Torsten Pilz, Paul Gallagher, Neil Mitchill Jr., Jennifer Rumsey and Jennifer Cunningham (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$21.0M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $21.0M across 123,435 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $21.0M

Sales with no 10b5-1 plan and no tax reference in the filing. $12.4M of it is Zoe Dickson. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Zoe Dickson, Feb 9, 2026

Taxes

59,163 shares ($6.2M) 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

More than usual: about 1.8x the 5-year average. 7 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.

James Fitterling: minor difference of 86 shares. Difference is under 0.5% of holdings.

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

Sources and methodology2,455 filings from SEC EDGAR, and how we read them

All 2,455 Forms 3, 4 and 5 filed for 3M (SEC CIK 66740) from Jul 9, 1996 to Oct 9, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 7 filings were left out because 3M filed them as an owner of another company's stock. 4 older filings exist only on paper and could not be read.

Probable 2-for-1 stock split on or before Sep 29, 2003 (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".
