Analyst Elizabeth Anderson highlighted the company's work to improve operational issues, and said CVS could be on the verge of regaining a four-star rating for its Medicare advantage plan from the Centers for Medicare and Medicaid Services. "CVS, like many [managed care organizations], is a complex organization, and we see a number of factors swinging in a positive direction, pointing to both a higher degree of confidence in [management's] outlook as well as supportive of higher valuation," Anderson said.
