Kathryn Chou sold 46% of vested holdings: 28K shares for $1.5M, all under a disclosed plan.Largest sale, Dec 11, 2025
Gabrielle Toledano sold 3.4K shares (34% of starting holdings), but 4.5K more vested, so the stake grew (from 10K to 11K).Largest sale, Jun 18, 2026

17 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (17 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 16 of 18 officers and directors. Left out: Robert Cardillo (holdings couldn't be fully reconciled); John Raymond (most of their shares vested during the period, so a percentage would mislead). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$7.1M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $7.1M across 149,090 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $7.0M · 99%

The lighter segment is sales with no plan disclosed in the filing ($93K), including tax-related sales outside a plan.

No plan disclosed · $93K

Sales with no 10b5-1 plan and no tax reference in the filing. $93K of it is John Raymond. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: John Raymond, Mar 12, 2026

Taxes

148,509 shares ($6.7M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 2 in this period

Officers and directors reported 2 purchases (Form 4 code P) in this period, and 4 across all their filings on record.

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. 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 uncertainty1 insider whose holdings couldn't be fully reconciled

Robert Cardillo: holdings couldn't be fully reconciled (difference of 72,520 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +77,520 shares on Feb 26, 2026 (Direct). Filing, Feb 26, 2026

Footnote: "The transactions reported on this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on March 12, 2025 and amended on June 13, 2025."

Inferred rename: "See Note 2" is treated as the same holder as "Bernal Trust", because the old name was never reported again and the new one opened with the same balance (4,453 shares). Old name, new name

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

Sources and methodology245 filings from SEC EDGAR, and how we read them

All 245 Forms 3, 4 and 5 filed for IonQ, Inc. (SEC CIK 1824920) from Nov 13, 2020 to Sep 15, 2026, retrieved from SEC EDGAR on Oct 7, 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".
