Amazon will dramatically expand its health-care reach with its planned $3.9 billion acquisition of One Medical, a primary care provider with 188 offices in 25 markets nationwide.
The e-commerce giant went big: It offered $18 a share for One Medical’s parent company, 1Life Healthcare — 77 percent higher than the previous day’s closing price. Sparks flew on Wall Street after Thursday’s announcement, powering the stock up nearly 70 percent.
