CVS Caremark Raises 2012 Estimate of Impact From Walgreens / Express Scripts Stalemate by 5 Cents

Company Expects to Retain At Least 50% of the Prescription Business Gained From the Stalemate in the Fourth Quarter

WOONSOCKET, R.I., July 19, 2012 /PRNewswire/ -- In light of this morning's news that Walgreens will re-enter Express Scripts broadest network on September 15th, 2012, CVS Caremark is now better able to clarify what we believe will be the overall estimate of the impact from the impasse for the remainder of 2012. The Company's existing guidance only reflects the estimated benefit from the stalemate continuing through the end of the second quarter. Given that the impasse is expected to last for nearly nine months and that the Company expects to retain at least 50% of the business gained from the impasse in the fourth quarter, the Company now expects an additional benefit from the impasse in the third and fourth quarters combined of approximately 5 cents per share.
