Alibaba Group Holding (BABA.NYSE) will shift the pharmacy branch of its Tmall online marketplace to Hong Kong-listed Alibaba Health Information Technology (0241.HKG), The Wall Street Journal reported, citing a filing to the Hong Kong Stock Exchange. The transfer will come in exchange for shares and convertible debt that will bring the partent company’s stake in the health firm to almost 55%, up from 38% currently. Alibaba is ramping up efforts to take a leading role in the medical industry as regulators rethink China’s health-care system; the firm said the deal would position it to sell prescription pharmaceuticals should reforms ultimately allow retailers to do so.
