ESRX: Innovation and Execution Building on a Proven Record for a Powerful Future March 2007


 

Express Scripts Offers Superior Value for Stockholders We believe we will clear anti-trust in a timely manner - additional consideration to compensate for timing of regulatory approval CVS acquisition of Caremark presents significant long-term risks Vertical integrations of PBMs have destroyed value CVS/CMX synergies don't add up CVS materially underperforms relative to Express Scripts in down markets ESRX offers more certainty of value and better currency ESRX has a strong record of innovation and execution ESRX profit generators have room to run ESRX confirms bullish outlook by increasing 2007 EPS guidance ESRX offers significant upside with or without Caremark Express Scripts has put forth a compelling proposal and has taken the necessary steps to complete this transaction


 

We Believe We Will Clear Anti-Trust in a Timely Manner Number of Fortune 500 Clients, by Service Provider At least 36 unique providers of pharmacy benefits services Notes: Source: Express Scripts Survey of Fortune 500 companies, Mar 2007 "Unknown" reflects 28 companies that did not respond to repeated inquiries (N = 23), received services from an unspecified "carved in" provider (N = 2), declined to provide information (N = 2), or were unavailable (N = 1) Express Scripts has identified these parties serving Fortune 500 companies. Many individual companies may be served by multiple providers of pharmacy benefits services. In such cases, we assigned the company to a single provider based on data available to us (e.g. number of lives served, carve-in versus carve-out). Consequently, the actual number of clients per provider may exceed that shown. Given the level of competition, we believe that we can successfully complete the regulatory review process in a timely manner

CVS/CMX Synergies Don't Add Up Adding PharmaCare's business to CMX's business unlikely to result in $500 million in PBM-specific synergies - translating to an unrealistic $7.00 per Rx CVS/CMX Drugs under management Manufacturer discounts Retail network contracting Direct processing costs/SGA Only partially managed Rebates generated on formulary management, not retail purchases Other retailers may refuse to offer competitive pricing to competitor- owned CMX Combining a small PBM with CMX results in few cost savings opportunities Fully managed Best practices will generate higher rebates; greater client savings Duplication from combining two large PBMs offer significantly more cost reduction opportunities ESRX/CMX Best practices will generate lower network rates; greater client savings


 

CVS Materially Underperforms Relative to Express Scripts in a Down Market Note: The graph above illustrates stock prices during the time period that corresponds to the S&P 500's peak to trough in the last cycle, which is March 24, 2000 through October 9, 2002. +142% (28%) (49%) Percent Return In a down market, Express Scripts stock should outperform CVS stock
