3 3 3 3 Safe Harbor Statement Cautionary Statement Regarding Forward-Looking Statements • This communication contains certain “forward-looking” statements as that term is defined by Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Statements that are predictive in nature, that depend on or relate to future events or conditions, or that include words such as “believes”, “anticipates”, “expects”, “may”, “will”, “should”, “estimates”, “intends”, “plans” and other similar expressions are forward-looking statements. Forward-looking statements involve known and unknown risks and uncertainties that may cause our actual results in future periods to differ materially from those projected or contemplated in the forward-looking statements as a result of, but not limited to, the following factors: the failure to receive, on a timely basis or otherwise, the required approvals by Amerigroup’s stockholders and government or regulatory agencies; the risk that a condition to closing of the proposed transaction may not be satisfied; Amerigroup’s and WellPoint’s ability to consummate the merger; the possibility that the anticipated benefits and synergies from the proposed transaction cannot be fully realized or may take longer to realize than expected; the failure by WellPoint to obtain the necessary debt financing arrangements set forth in the commitment letter received in connection with the merger; the possibility that costs or difficulties related to the integration of Amerigroup’s and WellPoint’s operations will be greater than expected; operating costs and business disruption may be greater than expected; the ability of Amerigroup to retain and hire key personnel and maintain relationships with providers or other business partners pending the consummation of the transaction; and the impact of legislative, regulatory and competitive changes and other risk factors relating to the industries in which Amerigroup and WellPoint operate, as detailed from time to time in each of Amerigroup’s and WellPoint’s reports filed with the Securities and Exchange Commission (the “SEC”). There can be no assurance that the proposed transaction will in fact be consummated. • Additional information about these factors and about the material factors or assumptions underlying such forward-looking statements may be found under Item 1.A in each of Amerigroup’s and WellPoint’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011, and Item 1.A in each of Amerigroup’s and WellPoint’s most recent Quarterly Report on Form 10-Q for the quarter ended March 31, 2012. Amerigroup and WellPoint caution that the foregoing list of important factors that may affect future results is not exhaustive. When relying on forward-looking statements to make decisions with respect to the proposed transaction, stockholders and others should carefully consider the foregoing factors and other uncertainties and potential events. All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to Amerigroup and WellPoint or any other person acting on their behalf are expressly qualified in their entirety by the cautionary statements referenced above. The forward-looking statements contained herein speak only as of the date of this communication. Neither Amerigroup nor WellPoint undertakes any obligation to update or revise any forward-looking statements for any reason, even if new information becomes available or other events occur in the future, except as may be required by law. |
