Leerink analyst David Larsen notes that Tricare recently announced that CVS Health (CVS) will be excluded from its network effective December 1 and Walgreens Boots Alliance (WBA) will be in-network. While there are over 127M scripts associated with Tricare each year, the analyst estimates that just about 30.6M of these prescriptions are "retail" and as a result Larsen does not believe that CVS' exclusion from the Tricare network will be material. He remains positive on CVS, and reiterates an Outperform rating and $105 price target on the company's shares.
