Nebius COO Sold $117M at $230; Stock Hits $129
NEW YORK, November 9 —
Four of Nebius Group N.V.'s (NBIS) most senior executives sold a combined $136 million in shares at $231 to $243 during a concentrated four-day window in early October, and the stock is now at $129, below even the range where a director stepped in as the lone insider buyer. Thursday's earnings report will begin to answer who read the business correctly.
- COO Ophir Nave sold exactly 500,000 shares on October 5 across 12 tranches at $231 to $243, totaling approximately $117.8 million.
- Director Arne Grimme made eleven consecutive open-market purchases from October 16 through October 29 at $153.96 to $169.99, spending approximately $330,000.
- Trailing-twelve-month revenue grew 454% year-over-year to $1.36 billion; gross margin stands at 74.3%.
The $145 Million Question
The selling pattern at Nebius, formerly Yandex N.V., the Russian internet giant that rebranded in August 2024, is unusually coordinated. CEO Arkadiy Volozh, CIO Andrey Korolenko, and CTO Danila Shtan each sold shares at $234.16 on October 1; four days later, COO Nave liquidated 500,000 shares across 12 disclosed tranches, the largest single tranche worth $25.1 million. Net insider activity over 90 days runs $145.2 million in sales against $330,000 in purchases. When four of a company's five most senior officers exit above $230 within a four-day window, the charitable reading, diversification, pre-scheduled 10b5-1 plans, competes with a less comfortable one: they saw headwinds the market had not priced.
Grimme's Eleven Bets
Against that selling, Director Arne Grimme bought on eleven consecutive trading days from October 16 through October 29, accumulating roughly 1,814 shares at $153.96 to $169.99 for approximately $330,000 total. The stock has since fallen another 18% to $129.49, putting Grimme underwater on every purchase. Grimme's bet rests on the fundamentals: Nebius builds GPU clusters, cloud platforms, and developer tools for the AI industry, operates under a strategic alliance with NVIDIA Corporation, and has posted two consecutive earnings beats, a 395.8% EPS surprise two quarters ago followed by a 20.8% beat most recently, after two prior misses of 20.3% and 62.8%. A DCF calculator run at current revenue trajectory and 74.3% gross margin produces a very different number than $129.

What Thursday Decides
The stock's setup before earnings is binary in a specific way. If Nebius reports revenue acceleration and raises forward guidance, the executive sales look like normal wealth-management and Grimme's accumulation looks prescient at prices now 46% below the COO's exit. If revenue growth decelerates or margins compress, the number to watch is whether gross margin holds above 70%, then $230 starts to look like a well-timed top and that level may not be the floor. The company also owns TripleTen, an edtech reskilling platform, and Avride, an autonomous driving and delivery robotics venture; neither drives the valuation at current multiples. The specific falsifier for the bull case is a gross margin print below 70%. Run the free Nebius Group N.V. deep-dive →

If gross margin holds above 70 percent alongside revenue acceleration, the executive sales look like normal wealth management and Grimme's buying looks prescient.
