REFLECT UNDERLYING STRENGTH OF COMPANY

WOONSOCKET, RHODE ISLAND, August 2, 2007—CVS Caremark Corporation (NYSE: CVS), today announced record revenues and earnings for the quarter ended June 30, 2007.

Net earnings for the second quarter ended June 30, 2007, increased 114.1% to $723.6 million or $0.47 per diluted share, compared with net earnings of $337.9 million or $0.40 per diluted share in the comparable 2006 period. Net earnings for the six months ended June 30, 2007 increased 69.7% to $1,132.5 million or $0.91 per diluted share, compared with net earnings of $667.5 million or $0.78 per diluted share in the comparable 2006 period. The Company estimates merger and integration costs associated with the March 22, 2007 merger between CVS Corporation and Caremark Rx, Inc. negatively impacted diluted earnings per share by $0.01 and $0.02 for the second quarter and first six months of 2007, respectively.

Tom Ryan, President and Chief Executive Officer of CVS Caremark stated: “This was an exceptionally strong quarter across our retail and pharmacy services segments. Sales growth was solid in the front store, pharmacy and PBM. Gross margin improved significantly, operating margins expanded meaningfully, and our diluted earnings per share grew 18%. At the same time, we’ve completed the initial merger integration activities, made sizeable progress on our cost synergy opportunities, and significantly advanced our new go-to-market strategies. Our continued strong performance in our core retail and PBM segments, coupled with these achievements related to our new business model, should pave the way for significant enterprise-wide growth in the future.”

Net revenues for the second quarter ended June 30, 2007, increased $10.1 billion to $20.7 billion, up from $10.6 billion during the comparable 2006 period. Same store sales (sales from stores open more than one year) in its CVS/pharmacy division rose 5.7%, while pharmacy same store sales rose 5.7% and front-end same store sales increased 5.9% for the second quarter ended June 30, 2007. Same store sales do not include the sales results of the drugstores acquired on June 2, 2006. These acquired stores will be included in same store sales following the one-year anniversary of the acquisition, beginning in fiscal July 2007.

For the second quarter, CVS Caremark opened 37 new stores, including one specialty pharmacy store, closed 15 stores and relocated 30 others.
