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

What stands out

Left out: Josef Parvizi, Xingjuan Chao, Raymond Woo, Scott Blumberg, Joseph Taylor, Joseph Manni, Erica Rogers, David Foehr, Bakker Tammenoms, William Burke, Rebecca Robertson, Sharon O'Keefe and Thomas West (share of stake is being verified).

Recent activity

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

Oct 1, 2026Raymond Woo sold 4.9K shares ($119K) under a disclosed trading plan. 4.9K shares came in from vesting or option exercises the same day, so the holding rose by 0 net.

Who	Shares	Price	% of total stake	Total stake after	Trade date	Filed
Raymond Woo Chief Technology Officer	4,887	$24.38	n/a	n/a	Oct 1, 2026	Oct 2, 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.

Outside holders, reported separately

TPG GP A, LLC sold $4.1M in the past 12 months. Large shareholders and the funds or companies that board members represent are not part of management, so they are left out of the figures above.

Common questions

Is the Ceribell, Inc. CEO selling stock?

Yes. Xingjuan Chao sold 560K shares ($11.1M) in the past 12 months, 97% of it under a trading plan disclosed in the filings.

Why are Ceribell, Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 95% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 3% were to cover taxes and 2% had no disclosed plan. A trading plan schedules sales in advance.

Are any Ceribell, Inc. insiders buying?

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

What explains the selling$18.8M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $18.8M across 926,507 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $17.8M · 95%

The lighter segment is sales with no plan disclosed in the filing ($950K), including tax-related sales outside a plan.

No plan disclosed · $408K

Sales with no 10b5-1 plan and no tax reference in the filing. $408K of it is Joseph Taylor. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Joseph Taylor, Aug 13, 2026

Taxes

$595K of sales (3.2%) cite tax obligations in their footnotes, $53K of them also under a plan. Separately, 5,405 shares ($74K) were withheld by the company for taxes, which isn't a market sale. Example: David Foehr, Aug 21, 2026

Known gaps and uncertainty13 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Ceribell, 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 methodology132 filings on record, 80 filed in the 12-month period, and how we read them

All 132 Forms 3, 4 and 5 on record for Ceribell, Inc. (SEC CIK 1861107), filed from Oct 10, 2024 to Oct 2, 2026; 80 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".
