CVS Health Corp. announced early Wednesday the management team that will serve once its acquisition of health insurer Aetna Inc. closes. Aetna Chief Financial Officer Shawn Guertin will serve as CVS Health’s executive vice president and chief financial officer, with CVS Health current CFO David Denton planning to leave the company at the deal’s close. Rick Jelinek, Aetna’s executive vice president, head of enterprise strategy, will serve as CVS Health’s executive vice president. Karen Lynch, who is currently Aetna’s president, will also be CVS Health’s executive vice president.
