Impact Evaluation

• Market Cap Context: Across Nebius Group's $60.10 billion market valuation, a $1.48M transaction is financially immaterial and unlikely to impact liquidity or pricing.
• Ownership Concentration: Boroditsky maintains zero direct common shares following the transaction but holds substantial exposure with 336,000 derivative stock options.
• Dilution Impact: The exercise of 7,000 options equates to an imperceptible 0.0028% dilution to existing shareholders.
• Transaction Significance: Low significance under SEC thresholds (<0.1% of market cap and shares outstanding).
