The waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), applicable to the proposed merger (the “Merger”) of Tree Merger Sub, Inc., a wholly-owned subsidiary of CVS Pharmacy, Inc., with and into Omnicare, Inc. (“Omnicare”) expired at 11:59 PM on Wednesday, August 5, 2015.

The expiration of the HSR Act waiting period satisfies a condition to the completion of the Merger.

Cautionary Statement Regarding Forward-Looking Statements

Certain statements in this communication may constitute “forward-looking statements” within the meaning of the federal securities laws. By their nature, all forward-looking statements involve risks and uncertainties. Actual results may differ materially from those contemplated by the forward-looking statements for a number of reasons as described in our Securities and Exchange Commission filings, including those set forth in the Risk Factors section and under the section entitled “Safe Harbor Statement under the Private Securities Litigation Reform Act of 1995 Regarding Forward-Looking Information” in our most recently filed Annual Report on Form 10-K and Quarterly Report on Form 10-Q. These forward-looking statements may be identified by words such as “believes”, “expects”, “anticipates”, “projects”, “intends”, “should”, “seeks”, “estimates”, “future” or similar expressions or by discussion of, among other things, strategy, goals, plans or intentions. The factors that could cause actual results to differ materially include the following: the possibility that the anticipated synergies and other benefits from the proposed merger of CVS Health Corporation (“CVS Health”) and Omnicare will not be realized, or will not be realized within the expected time periods; the inability to obtain regulatory approvals of the proposed merger (including the approval of antitrust authorities necessary to complete the proposed merger) on the terms desired or anticipated; the timing of such approvals and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed merger; the risk that a condition to closing the proposed merger may not be satisfied on a timely basis or at all; the risk that the proposed merger fails to close for any other reason; the risks and uncertainties related to CVS Health’s ability to successfully integrate the operations, products and employees of CVS Health and Omnicare; the effect of the potential disruption of management’s attention from ongoing business operations due to the pending merger; the effect of the announcement of the proposed merger on CVS Health’s and Omnicare’s relationships with their respective customers, vendors and lenders and on their respective operating results and businesses generally; access to available financing on a timely basis and on reasonable terms; the outcome of any legal proceedings related to the proposed merger; and the risks and uncertainties normally incidental to the long-term healthcare and pharmaceutical industries. The foregoing review of factors should not be construed as exhaustive and should be read in conjunction with other cautionary statements that are included elsewhere, including in Omnicare’s periodic reports filed with the U.S. Securities and Exchange Commission (the “SEC”). Copies of these filings, as well as subsequent filings, are available online at www.sec.gov and www.omnicare.com or on request from Omnicare. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. Except as

otherwise required by law, Omnicare does not undertake any obligation to publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.
