Methodology

"Proceeds" reflects IPO gross proceeds and, where disclosed and completed, includes the full exercise of the underwriters' option. It excludes concurrent private placements unless explicitly noted. "MCAP at IPO" is approximate market capitalisation at listing. "vs. offer" is based on share prices as of the 9 October 2026 refresh and will move with the market. Rows are sorted in reverse chronological order by pricing date. For how listing valuations and share counts are calculated, see valuation and fully diluted share terms.

Returns use Yahoo Finance’s 9 October regular-session closing quotes, excluding after-hours trades. TRexBio and Retension debuted on 9 October. Their offer market caps are pending verification of final post-IPO share counts. BlossomHill proceeds include the completed partial exercise of the underwriters’ option; ADARx proceeds include the full exercise closed on 1 October and exclude the concurrent AbbVie placement.
