Amazon acquires health provider One Medical for $3.9 billion

E-commerce giant Amazon announced Thursday it will acquire primary health care organization One Medical in a deal valued at roughly $3.9 billion, marking another expansion for the retailer into health care services.

Amazon said in a statement it will acquire One Medical for $18 per share in an all-cash transaction. Outside of the health care space, Amazon also owns grocery store chain Whole Foods, esports streaming service Twitch, home security doorbell service Ring and dozens of other subsidiaries. 

One Medical marks one of Amazon's biggest acquisitions, following its $13.7 billion deal to buy Whole Foods in 2017 and its $8.5 billion purchase of Hollywood studio MGM, which closed earlier this year.
