XOMA Royalty Corporation has entered into an agreement to acquire Generation Bio Co. for a cash price of $4.2913 per share at closing. In addition to the cash payment, Generation Bio stockholders will receive a non-transferable contingent value right $(CVR)$ per share, entitling them to potential future milestone payments. The acquisition will add Generation Bio's cell-targeted lipid nanoparticles (ctLNP) delivery platform for small interfering RNA (siRNA) and other nucleic acid therapies to XOMA Royalty's portfolio. The transaction is expected to close in February 2026, following the commencement of a tender offer and satisfaction of customary closing conditions. Approximately 15% of Generation Bio stockholders have already agreed to support the transaction.
