The drug store chain-slash-health care juggernaut got a $62 billion revenue boost—due to its $69 billion acquisition of Aetna, the insurance giant, in 2018. Though investors haven’t entirely sweetened on the deal, CEO Larry Merlo pronounced the integration of the two companies “successful” in February. Former Aetna CEO Mark Bertolini, meanwhile, resigned from the CVS board and said the integration was “far from over.” As a pharmacy retailer on the pandemic’s frontlines, CVS’s sales were brisk in the first quarter, but Merlo has warned about the “uncertainties” that surround the long-term performance of the company’s multifaceted business in a time of COVID-19.
