| Forward-Looking Statements Forward-looking Statements In addition to historical information, this presentation contains certain statements that constitute “forward-looking statements.” These forward-looking statements include, but are not limited to, all statements regarding the intent, belief or current expectations regarding the matters discussed or incorporated by reference in this document (including, but not limited to, statements as to “beliefs,” “expectations,” “anticipations,” “intentions” or similar words) and all statements which are not statements of historical fact. Such forward-looking statements, together with other statements that are not historical, are based on management’s current expectations and involve known and unknown risks, uncertainties, contingencies and other factors that could cause results, performance or achievements to differ materially from those stated. These risks and uncertainties include, but are not limited to, the possibility that Omnicare will not pursue a transaction with PharMerica, the timing to consummate a potential transaction between Omnicare and PharMerica, the ability and timing to obtain required regulatory approvals, Omnicare’s ability to realize the synergies contemplated by a potential transaction, Omnicare’s ability to promptly and effectively integrate the businesses of PharMerica and Omnicare, the performance of Omnicare’s institutional pharmacy business, business conditions in the institutional pharmacy industry generally, the inability to expand geographically as anticipated, the inability to leverage services and capabilities among Omnicare’s network of institutional pharmacies as anticipated, the effectiveness of Omnicare’s strategy in the institutional pharmacy business, the ability of the PharMerica acquisition to strengthen relationships with pharmaceutical and biotechnology companies and the risks and uncertainties described in Omnicare’s Form 10-K, Form 10-Q and Form 8-K reports filed with the Securities and Exchange Commission. Should one or more of these risks or uncertainties materialize or should underlying assumptions prove incorrect, Omnicare’s actual results, performance or achievements could differ materially from those expressed in, or implied by, such forward-looking statements. 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.
