Moody's gives CVS Caremark high rating among PBM competitors
NEW YORK — Moody's Investors Service compared the three largest pharmacy benefit managers — CVS Caremark, Express Scripts and Medco Health Solutions — in a report issued Tuesday. While it maintained a positive view of all three, it gave CVS Caremark the highest credit rating.
"CVS Caremark has the highest credit rating of the three companies and is the only one with a retail pharmacy business, providing it with size and diversity that offset financial metrics that are weaker than the company's PBM peers," the report stated.
