New York (NY) - December 16, 2025 - Cellectis (the "Company") (Euronext Growth: ALCLS - NASDAQ: CLLS), a clinical-stage biotechnology company using its pioneering gene-editing platform to develop life-saving cell and gene therapies, announces that the Arbitral Tribunal has issued its decision in the arbitration proceedings against Les Laboratoires Servier and Institut de Recherches Internationales Servier IRIS SARL ("Servier"), relating to the License, Development and Commercialization Agreement entered into between Servier and Cellectis on March 6, 2019, as amended (the "License Agreement").
