•  CVS Health announced that Karen Lynch will be its new CEO, succeeding Larry merlo, who is retiring.

Lynch runs the company's Aetna insurance business, and will step into the top job at CVS, the Wall Street Journal writes, as it is reaping the "benefits of its Aetna acquisition, which has fueled revenue gains and set the company apart from its struggling rival Walgreens Boots Alliance Inc."

The promotion also makes CVS "the largest company by revenue to be run by a female CEO," the Journal writes.
