Actionable Insight • Neutral

Traders should monitor the final pricing and size of the offering, which will impact the degree of dilution. The stock may experience downward pressure due to the new supply of shares and the lock-up expiration in 60 days. The success of the offering will provide insight into market sentiment for Celldex's clinical programs, particularly the upcoming Phase 3 data for barzolvolimab in CSU expected in Q4 2026.
