Expect significant selling pressure as the selling securityholder can immediately begin distributing shares once the registration becomes effective. The stock is likely to trade toward the $0.6261 exchange price as the market absorbs the overhang. Watch for the stockholder meeting by August 31, 2026 to approve removal of the 19.99% exchange cap, which would allow full conversion of the Notes and further dilution. The second tranche of up to $30M in additional Notes remains available, creating further downside risk.

Executive Summary
Senti Biosciences filed an S-3 shelf registration to register 15,971,890 shares of common stock for resale by its largest stockholder, Celadon Partners affiliate CPIF II-7 Limited. These shares are issuable upon exchange of $10M in Senior Secured Convertible Notes issued in May 2026 at an exchange price of $0.6261/share. The registered shares represent 51.2% of outstanding common stock, and the selling securityholder will become the controlling stockholder upon exchange. The company has a going concern warning with only $8.9M cash as of March 31, 2026, and received $9.7M net from the Notes. This resale registration removes volume restrictions, enabling the selling stockholder to sell a massive block into a thin market.
