The Board approved the Name Change pursuant to Section 242 of the General Corporation Law of the State of Delaware. In connection with the Name Change, the Board also approved the Amendment, effective as of July 10, 2024.

Pursuant to Section 242 of the Delaware General Corporation Law, stockholder approval was not required to complete the Name Change or to approve or effect the Amendment. The Name Change will not in any way affect the voting or other rights that accompany the Company’s common stock, par value $0.0075 per share (“Common Stock”), or the validity or transferability of the Company’s shares of Common Stock currently outstanding.

The Company’s Common Stock will continue to be quoted on The Nasdaq Global Market under the ticker symbol “XOMA”. There will be no change to the Company’s CUSIP in connection with the Name Change. Following the Name Change, existing stock certificates, which reflect the former name of the Company, will continue to be valid.
