The tender offer and related withdrawal rights expired one minute after 11:59 p.m. Eastern Time on Friday, February 6, 2026 (the "Expiration Date"). As of the Expiration Date, a total of 4,722,533 shares of Generation Bio common stock were validly tendered, and not validly withdrawn, representing approximately 70% of the outstanding shares of Generation Bio common stock as of the Expiration Date. As of the Expiration Date, the number of shares validly tendered in accordance with the terms of the tender offer and not validly withdrawn satisfied the minimum tender condition, and all other conditions to the tender offer were satisfied or waived. After the Expiration Date, XOMA Royalty irrevocably accepted for payment all shares validly tendered and not validly withdrawn and expects to promptly pay for such shares.

Following the closing of the tender offer, a subsidiary of the Company, XRA 7 Corp., merged with and into Generation Bio (the "Merger"), and all shares of Generation Bio common stock that had not been validly tendered and irrevocably accepted for purchase were converted into the right to receive the Offer Price without interest. As a result of the Merger, Generation Bio became a wholly owned subsidiary of XOMA Royalty. Following the closing of trading on The Nasdaq Stock Market LLC ("Nasdaq") on February 6, all shares of Generation Bio common stock ceased trading on Nasdaq, and the Company and Generation Bio intend promptly to cause such shares to be delisted from Nasdaq and deregistered under the Securities Exchange Act of 1934, as amended.
