MCHPMicrochip Technology · Insider ownership research

Microchip Technology insiders sold $71.0M in the past 12 months. How much of their stake is that?

About 24% overall. As a group they ended with more shares than they started with. These figures leave out Steve Sanghi, the largest holder (most holdings were last confirmed in 2019).

"% 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? More than usual: about 9x the 5-year average. 6 insiders sold; the average is 5 a year. Year by year

Two insiders sold $3.2M with no disclosed plan: Richard Simoncic ($1.9M) and Matthew Chapman ($1.2M). The filings don't state a reason.Richard Simoncic: largest such sale, May 13, 2026 · Matthew Chapman: largest such sale, May 15, 2026

Left out: Steve Sanghi and James Bjornholt (most holdings were last confirmed in 2019); Richard Simoncic (holdings couldn't be fully reconciled); Matthew Chapman (most holdings were last confirmed in 2016).
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 Microchip Technology CEO selling stock?

Yes. Steve Sanghi sold 739K shares ($64.4M) in the past 12 months, all of it under a trading plan disclosed in the filings.

Why are Microchip Technology insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 92% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 8% had no disclosed plan. A trading plan schedules sales in advance.

Are any Microchip Technology insiders buying?

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

How much of their stake did Microchip Technology insiders sell?

About 24% overall. As a group they ended with more shares than they started with. These figures leave out Steve Sanghi, the largest holder (most holdings were last confirmed in 2019). 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.

12 of 13 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (12 exactly, 0 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 9 of 13 officers and directors. Left out: Steve Sanghi and James Bjornholt (most holdings were last confirmed in 2019); Richard Simoncic (holdings couldn't be fully reconciled); Matthew Chapman (most holdings were last confirmed in 2016). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$71.0M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $71.0M across 814,399 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 ($5.3M), including tax-related sales outside a plan.

No plan disclosed · $5.3M

Sales with no 10b5-1 plan and no tax reference in the filing. $1.9M of it is Richard Simoncic. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Mathew Bunker, May 13, 2026

Taxes

128,214 shares ($10.1M) 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.

Sources and methodology2,378 filings from SEC EDGAR, and how we read them

All 2,378 Forms 3, 4 and 5 filed for Microchip Technology (SEC CIK 827054) from Aug 29, 2002 to Oct 5, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 2 filings were left out because Microchip Technology filed them as an owner of another company's stock. 55 older filings exist only on paper and could not be read.

Probable 2-for-1 stock split on or before Oct 12, 2021 (split date stated in a footnote). Splits aren't reported as transactions; 9 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".
