"% 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 and Michael Stone reported no open-market sales 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 BETA Technologies, Inc. CEO selling stock?

Yes. Kyle Clark sold 721K shares ($14.9M) in the past 12 months, 91% of it under a trading plan disclosed in the filings.

Why are BETA Technologies, Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 84% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 16% were to cover taxes. A trading plan schedules sales in advance.

Are any BETA Technologies, Inc. insiders buying?

Yes. 1 officer or director reported 3 purchases in the past 12 months (Form 4 code P; rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust are not counted).

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 BETA Technologies, 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 methodology80 filings on record, 80 filed in the 12-month period, and how we read them

All 80 Forms 3, 4 and 5 on record for BETA Technologies, Inc. (SEC CIK 1784570), filed from Nov 3, 2025 to Oct 9, 2026; 80 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 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".
