General Counsel Boaz Tal sold 5,100 shares for $1,016,904.60 via pre-arranged 10b5-1 plan

Boaz Tal, General Counsel of Nebius Group N.V., executed 3 separate sales totaling 5,100 shares for $1,016,904.60 on 2026-05-20 at blended average price of $199.39, pursuant to a 10b5-1 trading plan adopted on 2026-02-18. The transaction reduced his holdings to 80,754 shares, a 5.9% decrease from pre-transaction holdings of 85,854 shares. As a scheduled plan transaction, this sale reflects a pre-determined execution rather than a discretionary trading decision. The current price of $216.10 stands 7.5% below the 52-week high of $233.73, and the stock has appreciated 38.4% over the past 30 days and 120.7% over 90 days—context that frames the transaction within the broader price trajectory but does not characterize its timing.

Chief Revenue Officer sold 4,500 shares at $217.55; part of pre-arranged 10b5-1 plan, stock down -15.7% from 52-week high.

Marc Boroditsky, Chief Revenue Officer, executed a sale of 4,500 shares at $217.55 on 2026-05-15 for $978,975.00 as part of a pre-arranged 10b5-1 trading plan adopted on 2025-09-15, reducing his holdings from 42,162 shares to 37,662 shares. This is a scheduled transaction, not a discretionary choice, meaning timing relative to current market conditions is not a meaningful signal of insider sentiment. The stock currently trades at $197.08, down -15.7% from the 52-week high of $233.73, though up 30-day (+25.4%) and 90-day (+93.6%) in the near term. His prior sell at this ticker on 2026-04-15 was followed by gains, though with a pre-arranged trading plan in effect, such historical outcomes do not indicate conviction about valuation or forward outlook. For a company with a $49.9B market cap, the modest 10.7% reduction in this executive's position carries routine significance.

Nebius Group CIO Korolenko sells 500,000 shares for $101,620,000.00 amid strong 90-day rally of +125.8%

This filing contains 2 separate transactions: one sale of 500,000 shares at $0.00 and one sale of 500,000 shares at $203.24 on 2026-05-13, totaling $101,620,000.00. Chief Infrastructure Officer Korolenko's post-transaction holdings stand at 585,209 shares, down from 1,085,209 shares pre-transaction. The sale occurs as NBIS shares have gained +32.7% over the 30 days and +125.8% over the 90 days preceding the filing date, with the current price of $221.32 sitting at -5.3% from its 52-week high of $233.73. His two prior sells at NBIS — on 2026-04-06 and 2026-03-31 — were each followed by positive 90-day returns of +98.9% and +123.9% respectively at the ticker level, and his cross-ticker 90-day well-timed rate stands at 0.00%, meaning neither of his prior sells across all tickers preceded a stock decline within 90 days.

Director Bunina Elena sells 10,894 shares ($2.3M) at $203.18–$210.00 under scheduled 10b5-1 plan

Bunina Elena, a director at Nebius Group (market cap $56.0B), executed 2 separate sales on 2026-05-13 totaling 10,894 shares for $2,253,640.00, reducing her holdings from 21,666 to 10,772 shares. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2025-11-24 and therefore represents scheduled activity rather than discretionary choice. The stock currently trades at $221.32, approximately 5.3% below its 52-week high of $233.73, while the 30-day return stands at +32.7% and 90-day return at +125.8%.

Director Bunina Elena sells 10,819 shares totaling approximately $2M, continuing a streak of recent dispositions

Bunina Elena, a board director at Nebius, has disposed of more than ten thousand shares in two tranches totaling approximately two million dollars—her fourth major sale in the past month alone. Her prior three dispositions in this stock all saw shares rise afterward, meaning she exited at prices that proved to be local highs relative to what followed, a pattern of poorly-timed exits that now repeats with this large liquidation. The stock has surged dramatically in recent months and currently trades near the upper end of its yearly range, yet the director continues selling into strength rather than using any pullback as an opportunity to exit. There is no buying to offset these sales, and the cumulative effect—four sales in roughly four weeks—suggests the director views the stock's recent rally as an opportunity to reduce her stake rather than as a reason to hold through further upside.
