CMX Caremark RX

Caremark, Inc. (NYSE: CMX) said today it learned that a subsidiary of Express Scripts Inc. has undertaken efforts to nominate four directors for election at the next annual shareholders meeting of Caremark. Caremark said that this is yet another attempt by Express Scripts to interfere with its merger agreement with CVS. Any prospective board members who will be considered for election at the next annual shareholders meeting must be nominated in accordance with Caremark�s bylaws. Mac Crawford, Chairman, President and CEO of Caremark said, �We believe that Express Scripts� latest actions illustrate its desperation to disrupt our merger with CVS due to fear of competition from a combined CVS/Caremark and concern over the truly differentiated and innovative services that we will be able to offer customers as a result of this strategic transaction.� �Express Scripts is attempting to pressure Caremark�s Board of Directors. The fact is, our Board has already rejected Express Scripts� acquisition proposal and we are moving forward with our planned merger with CVS. We expect to be able to close the CVS/Caremark transaction in the first quarter of 2007,� continued Mr. Crawford. On January 7, 2007, Caremark announced that its Board of Directors, after thorough consideration and consultation with its legal and financial advisors, determined that the Express Scripts proposal did not constitute, and was not reasonably likely to lead to, a superior proposal. The Board unanimously concluded that pursuing discussions with Express Scripts was not in the best financial or strategic interests of Caremark and its shareholders. The Board unanimously affirmed its strong commitment to Caremark�s pending merger with CVS Corp. Caremark and CVS have received antitrust clearance and expect to close their merger by the end of the first quarter of 2007. The combination is expected to create in excess of $500 million in realizable cost synergies. This estimate does not include any potential revenue synergies resulting from the enhanced service offerings the combined company is expected to be able to offer to employers, plan sponsor and consumers. As a result of having received antitrust clearance, integration planning for a CVS/Caremark merger is underway, assuring achievement of synergies starting in 2007. Caremark and CVS have filed a joint proxy statement with the Securities and Exchange Commission and are proceeding forward to a vote on the pending merger at special shareholders meetings to be held in the first quarter of this year.
