Monitor for selling by RA Capital once the registration becomes effective. The out-of-the-money common stock warrants ($10 strike) limit immediate conversion risk, but the pre-funded warrants are essentially exercisable now. Watch for any filing of a 13D amendment or block trades from RA Capital.

Executive Summary
Karyopharm filed an S-3 shelf registration for the resale of up to 8,843,036 shares by RA Capital Healthcare Fund, consisting of 1,030,354 outstanding shares, 3,391,164 pre-funded warrant shares, and 4,421,518 common stock warrant shares. The company will receive no proceeds from this resale; the filing fulfills registration rights granted in the March 2026 private placement that raised $30M. The common stock warrants have a $10 exercise price (currently out of the money at $8.40), so near-term selling is likely limited to the already-issued shares.
Key Facts
- Registration covers 1,030,354 outstanding shares, 3,391,164 pre-funded warrant shares (exercise $0.0001), and 4,421,518 common stock warrant shares (exercise $10.00).
- Company receives no proceeds from resale; gross proceeds from original March 2026 private placement were $30M.
- Common stock warrants are out of the money (exercise $10 vs. current $8.40).
- RA Capital is currently limited to beneficial ownership of 9.99% (2,290,108 shares) but may increase that limit upon 61 days' notice.
Financial Impact
No new capital raised; registered shares represent ~39% of current shares outstanding (22.55M), creating potential overhang but no immediate dilution from new issuance.
Risk Factors
- Potential selling pressure from RA Capital's resale of the 1.03M outstanding shares and pre-funded warrant shares.
- Further dilution if the common stock warrants are exercised (requires stock price above $10).
