Equity compensation and insider-trading analyst

CTO executes small planned share sale under Rule 10b5-1.

The Nebius Group N.V. Chief Technology Officer, Danila Shtan, completed an open-market sale of 15,678 Class A Shares at $238.9621 per share on June 4, 2026. Following the transaction, he still directly owns 291,700 Class A Shares.

This is a straightforward insider sale coded “S,” with no derivative exercises or restructurings reported. The remaining holding shown in the filing suggests he retains a substantial equity position relative to the shares sold in this event.

A key detail is that the sale occurred pursuant to a Rule 10b5-1 trading plan adopted on March 6, 2026. Such plans are set up in advance, so the timing of individual trades generally reflects pre-arranged diversification rather than a new view on Nebius Group’s prospects.

Rule 10b5-1 trading plan regulatory

"The sales reported on this Form 4 were made pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on March 6, 2026."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

open-market sale financial

"transaction_action: open-market sale"

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

non-derivative financial

"transaction_type: non-derivative"

Class A Shares financial

"security_title: Class A Shares"

Class A shares are one of a company’s distinct types of stock that come with a specific set of rights—commonly different voting power, dividend treatment, or transfer rules—defined in the company’s charter. Investors care because those rights affect control, income and resale value; like holding a seat at a table that has different rules or stronger chips than other seats, owning Class A changes how much influence and return you can expect.
