------

On September 26, 2025, Factor Bioscience Inc. ("Factor") filed a complaint in the United States District Court for the District of Delaware against our gene-editing technology licensor, Cellectis S.A., and its affiliate Cellectis, Inc. (collectively, "Cellectis"), alleging that Cellectis's TALEN-based gene-editing technology infringed three of Factor's U.S. patents relating to gene-editing techniques. Among other things, Factor alleges that Cellectis copied Factor's patented mRNA TALEN technology, passed off as Cellectis's own and entered into license agreements with several licensors, including us, to capitalize on such infringement. Factor's complaint also names AstraZeneca PLC and certain of its affiliates (collectively, "AstraZeneca") as defendants, and alleges direct infringement by AstraZeneca of certain of Factor's patents by using Cellectis's allegedly infringing TALEN technology.

Cellectis notified us of the patent infringement action on October 6, 2025, and informed us that it disputes Factor's claims and intends to vigorously defend against them. Although we are not a party to this litigation, we rely on the TALEN gene-editing technology licensed from Cellectis to engineer certain of our allogeneic CAR T cell product candidates, including cema-cel and ALLO-316. Factor may also choose to assert direct claims against us as a commercial user of the disputed technology. Risks associated with our reliance on Cellectis's TALEN gene-editing technology, as well as other intellectual property risks, are described under the "Risk Factors" heading of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, as filed with the Securities and Exchange Commission on August 13, 2025, including under the headings "Gene-editing is a relatively new technology, and if we are unable to use this technology in our intended product candidates, our revenue opportunities will be materially limited," "We are heavily reliant on our partners, Cellectis and Servier, for access to TALEN gene editing technology for the manufacturing and development of our oncology product candidates," "Third-party claims of intellectual property infringement may prevent or delay our product discovery and development efforts and our ability to commercialize our product candidates," and "We may not be successful in obtaining or maintaining necessary rights to product components and processes for our development pipeline through acquisitions and in-licenses."
