"% 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.

Sep 17, 20265 executives had 8.5K shares ($2.4M) withheld by the company for taxes (not a market sale). That is between 0.9% and 3.0% of each person's total stake held that day.

What stands out

Four officers sold more than 25% of vested holdings: Anirudh Devgan (76% of holdings, $58.7M, all under a disclosed plan), John Wall (77% of holdings, $17.3M, all under a disclosed plan) and Chin-Chi Teng (29% of holdings, $12.3M, all under a disclosed plan), plus 1 more.Anirudh Devgan: largest sale, Jun 1, 2026 · John Wall: largest sale, Apr 16, 2026 · Chin-Chi Teng: largest sale, Dec 8, 2025
Two insiders sold shares but ended with larger stakes, because more shares came in than were sold: Paul Cunningham (sold 15K, 15% of starting holdings; 64K added) and Moshe Gavrielov (sold 25, 2.4% of starting holdings; 798 added).Paul Cunningham: largest sale, Jun 15, 2026 · Moshe Gavrielov: largest sale, Dec 2, 2025

Percentages cover 15 of 16 officers and directors. Left out: hove Van den (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 Cadence Design Systems CEO selling stock?

Yes. Anirudh Devgan sold 154K shares ($58.7M, 76% of starting holdings) in the past 12 months, all of it under a trading plan disclosed in the filings.

Why are Cadence Design Systems insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 100.0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 0.0% had no disclosed plan. A trading plan schedules sales in advance.

Are any Cadence Design Systems insiders buying?

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

How much of their stake did Cadence Design Systems insiders sell?

About 44% overall. As a group they ended with more shares than they started with. 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.

16 of 16 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (10 exactly, 6 with a minor or footnoted difference). Percentages cover 15 of 16 officers and directors. Left out: hove Van den (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$104M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $104M across 289,075 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 ($8K), including tax-related sales outside a plan.

No plan disclosed · $8K

Sales with no 10b5-1 plan and no tax reference in the filing. $8K of it is Moshe Gavrielov. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Moshe Gavrielov, Dec 2, 2025

Taxes

202,570 shares ($59.4M) were withheld by the company for taxes, which isn't a market sale.

Charitable gifts · 1.1K 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.

Inferred rename: "As Custodian for Minor Children" is treated as the same holder as "As Custodian for Children", because the old name was never reported again and the new one opened with the same balance (11,420 shares). Old name, new name

Inferred rename: "As Custodian for Children" is treated as the same holder as "As Custodian for Child", because the old name was never reported again and the new one opened with the same balance (26,520 shares). Old name, new name

Inferred rename: "Trust" is treated as the same holder as "Held in Trust", because the old name was never reported again and the new one opened with the same balance (229,388 shares). Old name, new name

Inferred typo: the share class "Commin Stock" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Lip Tan, 182,008 shares): old title, new title

Inferred typo: the share class "Comomn Stock" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (William Porter, 279,187 shares): old title, new title

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

Sources and methodology1,710 filings from SEC EDGAR, and how we read them

All 1,710 Forms 3, 4 and 5 filed for Cadence Design Systems (SEC CIK 813672) from Nov 20, 2002 to Oct 5, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 1 filing was left out because Cadence Design Systems filed them as an owner of another company's stock. 18 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".
