SHANGHAI, China – July 27, 2021 – I-Mab (the “Company”) (Nasdaq: IMAB), a clinical stage biopharmaceutical company committed to the discovery, development and commercialization of novel biologics, today announced that on July 27, 2021, the Board of Directors of the Company (the “Board”) approved a preliminary proposal for the potential dual listing of the Company’s newly issued shares on the Science and Technology Innovation Board of the Shanghai Stock Exchange (the “STAR Board”).
