CVS/Caremark Merger Enhances
Shareholder Value
Our Board gave careful consideration to the Express
Scripts proposal.  In the end, our conclusion was
simple and straightforward: 
Express’
proposal is not in the best interests of
Caremark, its shareholders, customers and consumers. 
Caremark believes that future success does not lie in
simply creating a larger PBM, but in becoming an end-
to-end provider of diversified pharmaceutical services
and integrated healthcare solutions, thereby enhancing
Caremark’s already strong clinical outcomes and
creating unique opportunities to improve consumers’
health, control costs and meet the needs of payors.
