"% of total stake" is the shares in this event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings don't reconcile, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Is this normal? Less than usual: about a quarter of the 5-year average. 7 insiders sold; the average is 7 a year. Year by year

What stands out

Routine activity: 98% of sales were under disclosed plans, and no insider sold more than 100% of vested holdings.

Percentages cover 8 of 20 officers and directors. 12 are left out

i
Left out: Brian Tyler, Michele Lau, LeAnn Smith, Thomas Rodgers and Napoleon Rutledge Jr. (most of their shares vested during the period, so a percentage would mislead); Donald Knauss (most holdings were last confirmed in 2023); James Hinton, Webster Dunbar, Deborah Dunsire, Julie Gerberding, Lynne Doughtie and Kenny Cheung (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 McKesson Corporation CEO selling stock?

Yes. Brian Tyler sold 22K shares ($17.0M) in the past 12 months, all of it under a trading plan disclosed in the filings.

Why are McKesson Corporation insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 98% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 2% had no disclosed plan. A trading plan schedules sales in advance.

Are any McKesson Corporation insiders buying?

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

How much of their stake did McKesson Corporation insiders sell?

About 2.0% overall. As a group they ended with more shares than they started with. 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.

20 of 20 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (17 exactly, 3 with a minor or footnoted difference). Percentages cover 8 of 20 officers and directors. Left out: Brian Tyler, Michele Lau, LeAnn Smith, Thomas Rodgers and Napoleon Rutledge Jr. (most of their shares vested during the period, so a percentage would mislead); Donald Knauss (most holdings were last confirmed in 2023); James Hinton, Webster Dunbar, Deborah Dunsire, Julie Gerberding, Lynne Doughtie and Kenny Cheung (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$28.3M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $28.3M across 35,470 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

The lighter segment is sales with no plan disclosed in the filing ($597K), including tax-related sales outside a plan.

No plan disclosed · $597K

Sales with no 10b5-1 plan and no tax reference in the filing. $328K of it is Maria Martinez. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Maria Martinez, Feb 19, 2026

Taxes

30,013 shares ($23.2M) 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.

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

Sources and methodology1,372 filings from SEC EDGAR, and how we read them

All 1,372 Forms 3, 4 and 5 filed for McKesson Corporation (SEC CIK 927653) from May 23, 2001 to Sep 10, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 2 filings were left out because McKesson Corporation filed them as an owner of another company's stock. 40 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".
