Serving more than 100 million customers through its pharmacy benefit manager CVS Caremark and managed care company Aetna, CVS Health (NYSE: CVS) is a company critical to the healthcare sector. It's a safe bet that as long as there is still a need for prescriptions and health insurance, the company will likely do well for its shareholders. This is why analysts believe that CVS Health's non-GAAP (generally accepted accounting principles) adjusted diluted earnings per share (EPS) will compound by 5.9% annually over the next five years.
