The effective shelf opens the door for immediate warrant conversions and resales, likely adding persistent downward pressure. Monitor for a Form 424B5 prospectus supplement or insider selling filings (Form 4) that would signal the start of actual share sales.

Executive Summary
Accuray's S-3 shelf registration (File No. 333-297855) became effective on September 11, 2026. This allows the resale of 6,834,308 shares by existing lenders/warrant holders, creating an immediate dilution overhang. The deeply in-the-money Penny Warrants ($0.01 strike vs. ~$0.29 stock price) represent a significant potential selling pressure on a $30M market cap company.
Key Facts
- S-3 shelf registration became effective on September 11, 2026
- Covers 6,834,308 shares for resale by existing lenders/warrant holders
- Penny Warrants exercisable at $0.01 per share are deeply in-the-money
- Company will not receive any proceeds from the resale
- Market cap is only ~$30M, making the potential dilution highly material
Financial Impact
Up to 6.8M shares of potential selling pressure on a ~$30M market cap company; dilution overhang of roughly 20-25% of current float
Risk Factors
- Immediate dilution overhang from warrant conversions
- No company proceeds from resale — pure selling pressure
- Low market cap makes the relative impact of 6.8M shares very large
