Amazon.com Inc. (AMZN) said Thursday it has signed an agreement to acquire One Medical, a primary care organization that operates under 1Life Healthcare Inc. (ONEM), for $18 a share in cash, or $3.9 billion including debt. The stock closed Wednesday at $10.18 . "We think health care is high on the list of experiences that need reinvention," Neil Lindsay , senior vice president of Amazon Health Services said in a statement. He cited a list of inconveniences associated with health care, including time needed to make a booking, taking time off work, finding a parking spot near a clinic and then accessing a pharmacy. Once the deal closes, Amir Dan Rubin will remain CEO of One Medical. Amazon has made a series of moves in the health care space, including acquiring online pharmacy PillPack in 2019. One Medical stock soared 67% premarket after resuming trading following a halt, but has fallen 42% in the year to date, while the S&P 500 has fallen 17%.
