CVS Pleased with Caremark’s Rejection of Express Scripts’ Highly Conditional, Unsolicited Offer

WOONSOCKET, R.I.--(BUSINESS WIRE)--In response to the decision announced by the Board of Directors of Caremark Rx, Inc. (NYSE: CMX) relating to Express Scripts’ (NYSE: ESRX) unsolicited offer, CVS Corporation (NYSE: CVS) issued the following statement:

“We are pleased with the decision of the Caremark board to reaffirm its commitment to the merger of CVS and Caremark and we look forward to closing our transaction during the first quarter of 2007,” said Tom Ryan, Chairman, President and Chief Executive Officer of CVS. “With the FTC antitrust waiting period already expired and our joint proxy statement on file at the SEC, we remain firmly committed to completing our combination and passing along the many benefits to shareholders, employers, plan sponsors and consumers as soon as possible.”

CVS noted the following:

The merger of CVS and Caremark offers a clear path and substantially
more certainty to close.

        The Express Scripts offer is highly conditional. Specifically,
        the Express Scripts offer, which would reduce the number of
        major competitors in the PBM industry from 3 to 2, carries
        significant antitrust risk that could well prevent it from
        ever being approved and, at a minimum, would substantially
        delay closing of the transaction, with adverse consequences.
        In contrast, the antitrust waiting period for the CVS/Caremark
        transaction has already expired without a second request, and
        the proxy statement is already on file with the SEC. The
        planned first quarter closing will enable the merged
        CVS/Caremark to quickly begin to offer benefits to
        shareholders, employers, plan sponsors and consumers.

A combined Express Scripts/Caremark would likely result in substantial
customer defections and diminished value, particularly in light of the
high degree of leverage.

        Caremark has expressed its deep concern about key customer
        defections in the event of a combination with Express Scripts.
        The loss of key customers presents an unacceptable risk to
        shareholders, particularly in light of the leverage profile of
        a combined Caremark/Express Scripts. This should be of concern
        to Caremark shareholders, who would own 57% of the combined
        company. Express Scripts has also made unsubstantiated claims
        about synergies, which could be substantially revised
        following due diligence. In contrast, CVS has had the
        opportunity to conduct extensive due diligence and integration
        planning and now conservatively estimates a minimum of $500
        million in pre-tax cost synergies.

CVS/Caremark will offer fully integrated products and services that
will accelerate revenue growth.

        The CVS/Caremark combination will provide significant
        opportunities to drive incremental revenues that only a
        leading drugstore/PBM combination can achieve. Payors and
        consumers have been seeking new ways to control costs, reduce
        complexity, and improve health outcomes. Trends affecting the
        healthcare industry, including an aging population, the trend
        toward consumer driven healthcare, the need for greater
        compliance with prescribed drug therapies, the increasing use
        of high cost specialty drugs and the increasing need for
        tailored disease management programs, all require new products
        and services that can be more effectively delivered by the
        fully integrated CVS/Caremark.

CVS/Caremark offers substantially greater shareholder value than the
highly conditional Express Scripts' offer.

        The vertical integration of CVS/Caremark will enable the new
        company to develop and offer unique products and services that
        will reduce costs, improve outcomes, accelerate revenue growth
        and create substantial shareholder value. In addition, CVS and
        Caremark expect the combination to be accretive to EPS in the
        first full year after close and increasingly accretive
        thereafter. With the very significant free cash flow
        generation capabilities of the combined company, as well as
        the strength of the post-merger balance sheet, CVS/Caremark
        will be well positioned to capitalize on strategic
        opportunities and enhance total return to shareholders through
        significant common share repurchases and dividends.

CVS/Caremark shareholders will benefit from the highly skilled
Caremark management team.

        The CVS/Caremark merger of equals will enable CVS/Caremark
        shareholders to benefit from having the Caremark management
        team run the combined PBM business. At the same time, a new
        team comprised of both CVS and Caremark will be transforming
        the delivery of pharmacy products and services to this
        changing marketplace. This is a relationship business and one
        of the best attributes of the combined company will be the
        strength of the management teams, which will stay in place.

CVS and Caremark have extensive experience in integrating large-scale
acquisitions, while Express Scripts has never integrated an
acquisition of this size.

        CVS has a long and successful track record of executing
        successful integrations, including Osco/Sav-on, Eckerd, Revco
        and Arbor. Caremark has successfully integrated the largest
        PBM acquisition ever with its purchase of AdvancePCS. In the
        CVS/Caremark merger, Caremark will be integrating CVS' $3
        billion revenue PBM, PharmaCare, into Caremark, a far more
        manageable undertaking than their previous successful
        integration.
