Recent activity

Past 30 days, Sep 17, 2026 to Oct 16, 2026

Sep 21, 2026Naixi Wu sold 3.8K shares ($12K) to cover taxes on vesting stock.

Who	Shares	Price	% of total stake	Total stake after	Trade date	Filed
Naixi Wu Chief Financial Officer Also under a disclosed plan	3,750	$3.18	n/a	n/a	Sep 21, 2026	Sep 22, 2026

"% of total stake" is the shares in an 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 are not confirmed, 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.

Common questions

Is the indie Semiconductor, Inc. CEO selling stock?

Yes. Donald McClymont sold 651K shares ($2.5M) in the past 12 months, 37% of it under a trading plan disclosed in the filings.

Why are indie Semiconductor, Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 60% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 14% were to cover taxes and 26% had no disclosed plan. A trading plan schedules sales in advance.

Are any indie Semiconductor, Inc. insiders buying?

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

What explains the selling$15.4M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $15.4M across 3,759,483 shares. Plan status and stated purpose are separate questions, and a sale can have both.

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.

Known gaps and uncertainty11 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for indie Semiconductor, Inc. are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

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

Sources and methodology359 filings on record, 87 filed in the 12-month period, and how we read them

All 359 Forms 3, 4 and 5 on record for indie Semiconductor, Inc. (SEC CIK 1841925), filed from Jun 21, 2021 to Sep 22, 2026; 87 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages.

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".
