[F-3] Adagene Inc. Foreign Issuer Shelf Registration
Adagene Inc. filed a Form F-3 resale registration covering up to 10,625,000 ordinary shares or 8,500,000 ADSs to be offered from time to time by a selling shareholder. The registered securities are issuable upon conversion of 1,062,500 Series A Non-Voting Redeemable Convertible Preferred Shares that were sold in a private placement.
Adagene is not selling any securities and will receive no proceeds from sales under this prospectus; the selling shareholder will receive all sale proceeds. Each ADS represents 1.25 ordinary shares, and the ADSs trade on Nasdaq as ADAG. Sales may occur in public or private transactions at market or negotiated prices.
The prospectus highlights PRC-related regulatory and operational risks, including potential impacts from cybersecurity and data rules, and notes the historical HFCAA context regarding PCAOB inspections. Counsel indicates this secondary offering is not subject to CSRC filing based on current guidance.
