Express Scripts Positioned for Strong Growth After Caremark Vote

Innovation and Execution Delivers Value for Stockholders, Plan Sponsors and Patients 


ST. LOUIS, March 16  /PRNewswire-FirstCall/ -- Express Scripts, Inc. (NASDAQ:ESRX) today issued the following statement from president, chief executive officer and chairman George Paz commenting on the approval by Caremark Rx, Inc. (NYSE:CMX) stockholders of Caremark's acquisition by CVS Corporation (NYSE:CVS).

      "First of all, I want to thank the stockholders of both Caremark and
      Express Scripts for their consideration during this effort, our
      advisors for their assistance and, most especially, every Express
      Scripts employee for their many contributions.

      "Since presenting our offer on December 18, 2006, we have appreciated
      the opportunity to talk about the pharmacy benefit management (PBM)
      model to investors across the nation.  The strength of the PBM model
      and our mission to make the use of prescription drugs safer and more
      affordable resonated extremely well with them.

      "We earned the support of respected organizations like the labor
      movement's Change to Win coalition, as well as the investor advisory
      services, Glass Lewis, Proxy Governance and Egan-Jones.  Particularly
      gratifying was the CalPERS announcement that it had voted against the
      acquisition on both the CVS and Caremark proxies.

      "During our effort to acquire Caremark, we stayed focused on serving
      plan sponsors and patients.  Our year is off to such a good start that
      we were able to increase our 2007 diluted earnings per share guidance.

      "Express Scripts' fundamental business model continues to produce
      outstanding results.  We have considerable room to run in saving plan
      sponsors and patients money through greater use of generics, home
      delivery and specialty pharmacy.  Last year, we saved clients and
      patients $126 million in the anti-cholesterol drug class alone.

      "As we move forward, Express Scripts will continue to lead in:

        * Developing sophisticated trend management tools, including
          generic, specialty drug and home delivery programs;

        * Engaging patients as active health care consumers to choose more
          cost effective generics, lower cost brands and home delivery;

        * Working with Congress to create a biogenerics pathway, which could
          unlock approximately $70 billion of savings for our nation over
          the next decade; and

        * Using our independence to drive down costs via competition among
          all players in the supply chain, including retail pharmacies and
          drug manufacturers."
