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.
