WOONSOCKET, RHODE ISLAND, January 31, 2008—CVS Caremark Corporation (NYSE: CVS), today announced record revenues and earnings for the fourth quarter and fiscal year ended December 29, 2007.

Net earnings for the fourth quarter ended December 29, 2007, increased 95.3% to $815.0 million or $0.55 per diluted share, compared with net earnings of $417.2 million or $0.49 per diluted share in the comparable 2006 period. Adjusted diluted earnings per share for the fourth quarter ended December 29, 2007 were $0.58, compared with $0.52 per share in the comparable 2006 period. Net earnings for the full year 2007 increased 92.6% to $2.6 billion or $1.92 per diluted share, compared with net earnings of $1.4 billion or $1.60 per diluted share in 2006. Adjusted diluted earnings per share for the full year ended December 29, 2007 were $2.07, compared with $1.72 per 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 approximately $0.01 and $0.05 for the fourth quarter and full year 2007, respectively.

Tom Ryan, Chairman, President and Chief Executive Officer of CVS Caremark said, “2007 was a milestone year for CVS Caremark, and we accomplished a great deal across our business units. At the same time, we remained focused on service, execution, and expense control, which yielded exceptional financial performance. Solid revenue growth and improved gross margins in both the Retail and PBM segments drove expanded operating margins and healthy earnings growth. We attained our goal of generating $2 billion in free cash flow, and launched a $5 billion share repurchase program, slated to be fully complete by the end of the first quarter of this year.”

Mr. Ryan continued, “We also set the stage for significant future growth with the completion of our transformational merger. From this platform, we are creating a unique and differentiated position in the marketplace, which will enable us to reduce the costs and complexities of healthcare for payors and consumers, while improving health outcomes.”

“I am extremely proud of the dedicated individuals across our company who accomplished our 2007 goals. With our industry-leading team and our unparalleled expertise, I see a very significant opportunity to gain share and create new sources of revenue,” concluded Mr. Ryan.

Net revenues for the thirteen-week period ended December 29, 2007, increased $9.8 billion to $21.9 billion, up from $12.1 billion during the thirteen-week period ended December 30, 2006. Same store sales (sales from stores open more than one year) in the Company’s CVS/pharmacy division for the fourth quarter rose 3.4% over the prior year period. Pharmacy same store sales rose 3.6% and were negatively impacted by approximately 450 basis points due to recent generic introductions, while front-end same store sales increased 2.9%.
