Trading & Market Considerations

• Significance: High. A capital raise of this scale will dominate near-term market sentiment, introducing potential supply overhang from newly issued shares and long-dated Series C warrant coverage ($69.46 strike).
• Lock-Up: Directors and executive officers are subject to standard 30-day lock-up agreements.
