As previously reported, CLSA analyst David Li downgraded BeiGene to Outperform from Buy following the news yesterday of Bristol-Myers' (BMY) proposed acquisition of Celgene (CELG) in a note titled "From friend to foe." He thinks Celgene is unlikely to continue to cooperate with BeiGene on its PD-1 after the deal goes through and also worries about the three commercialized products licensed from Celgene and about the company selling out of its BeiGene stake, he tells investors. He lowered his price target on BeiGene shares to HK$89.86 from HK$121.34.
