"% 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.

Common questions

Is the Nebius Group N.V. CEO selling stock?

Yes. Arkadiy Volozh sold 118K shares ($23.3M, 0.4% of starting holdings) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Nebius Group N.V. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 83% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 17% were to cover taxes. A trading plan schedules sales in advance.

Are any Nebius Group N.V. insiders buying?

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

How much of their stake did Nebius Group N.V. insiders sell?

About 0.6% overall. As a group they ended with more shares than they started with. That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

14 of 15 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (13 exactly, 1 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 7 of 15 officers and directors. Left out: John Boynton IV (holdings couldn't be fully reconciled); Ophir Nave, Marc Boroditsky, Elena Bunina, Andrey Korolenko and Danila Shtan (most of their shares vested during the period, so a percentage would mislead); Maria del Dado Alonso Sanchez and Yael Almog (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$317M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $317M across 1,485,619 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 ($53.2M), including tax-related sales outside a plan.

Taxes

$53.2M of sales (16.8%) cite tax obligations in their footnotes. Example: Danila Shtan, Oct 1, 2026

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 uncertainty1 insider whose holdings couldn't be fully reconciled

John Boynton IV: holdings couldn't be fully reconciled (difference of 45,000 shares). Balance changed with no matching transaction and no footnote: +45,000 shares on Jun 15, 2026 (Direct). Filing, Jun 15, 2026

Matthew Weigand: minor difference of 9,102 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

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

Sources and methodology58 filings from SEC EDGAR, and how we read them

All 58 Forms 3, 4 and 5 filed for Nebius Group N.V. (SEC CIK 1513845) from Mar 18, 2026 to Oct 6, 2026, retrieved from SEC EDGAR on Oct 8, 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".
