We initiate coverage on 3SBio, a potential global winner from I/O 2.0, at Buy with a Equity

DCF-based PO of HKD23.0. Our positive views are supported by the following catalysts

and drivers: i) expected Phase II readouts in 2H26 for SSGJ-707 plus chemo in 1L NSCLC David Li >> Research Analyst

and 1L mCRC, which could further validate its efficacy profile and support global Merrill Lynch (Hong Kong)

clinical updates at major conferences over the past year and the initiation of 11 clinical Price 16.92 HKD
