Chief Infrastructure Officer Andrey Korolenko sells 33,871 shares of NBIS at $235.45 for $7,974,926.95; stock now -26.5% from 52-week high

Korolenko sold 33,871 shares at $235.45 on 2026-07-01, reducing his position by 5.8% to 551,338 shares. The transaction occurred when NBIS was trading well below its 52-week high of $299.86, now down 26.5%, though the sale price was significantly above the current $220.45. His prior three sales at NBIS showed mixed timing: the April 6 and March 31 sells preceded gains of 93.9% and 164.4% respectively over 90 days, indicating these were poorly-timed exits. The current transaction follows a 87.8% 90-day rally, suggesting the stock has appreciated substantially since late March. The pattern of consecutive sales across multiple months, combined with recent strong price appreciation, merits tracking for any signals about executive conviction in current valuations at this $55.8B market cap company.

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.

CIO Andrey Korolenko sold 31,357 shares of Nebius (NBIS) at $111.20 on 2026-04-06, retaining 585,209 shares post-sale.

Korolenko sold 31,357 shares (5.1% of pre-transaction holdings) one day after a prior sale on 2026-03-31, continuing a pattern of recent dispositions. The sales occurred as NBIS trades near its 52-week high ($125.00 current vs. $135.46 52-week peak), with the stock up 31.7% over 30 days and 28.5% over 90 days. His cross-ticker track record shows only 1 prior sell, making this pair of near-consecutive sales at this ticker a notable shift in activity. The timing outcome of the prior March 31 sale cannot yet be measured, limiting visibility into whether these dispositions preceded a decline or occurred during momentum.

Chief Infrastructure Officer Korolenko sold 26,976 shares at $98.78; still holds 616,566 shares post-sale.

Korolenko Andrey, Chief Infrastructure Officer, sold 26,976 shares (27.0K shares) of Nebius Group at $98.78 on 2026-03-31, reducing his holdings from 643,542 shares to 616,566 shares—a net decrease of 4.2% of his pre-transaction stake. The sale occurred at a price $3.17 below the current price of $101.95, and notably well below the 52-week high of $135.46. The stock has posted strong recent momentum, with a +12.0% 30-day change and +21.8% 90-day gain, suggesting market strength at the time of the sale. The modest share reduction (26,976 shares from a 643.5K base) and the retention of substantial holdings (616.6K shares post-sale) indicate a partial portfolio adjustment rather than a significant conviction reversal by the CIO.
