Forward Looking Statements
Information set forth herein contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995, which involve a number of risks and uncertainties. Alkermes cautions readers that any forward-looking information is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking information. Such forward-looking statements include, but are not limited to, statements about the benefits of the business combination transaction involving EDT and Alkermes, including future financial and operating results, the combined company’s plans, objectives, expectations (financial or otherwise) and intentions and other statements that are not historical facts.
The following factors, among others, could cause actual results to differ from those set forth in the forward-looking statements: the ability to obtain regulatory approvals of the transaction on the proposed terms and schedule; the failure of Alkermes’ stockholders to approve the transaction; the outcome of pending or potential litigation or governmental investigations; the risk that the businesses will not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected; uncertainty of the expected financial performance of Alkermes plc following completion of the proposed transaction; Alkermes plc’s ability to achieve the cost savings and synergies contemplated by the proposed transaction within the expected time frame; disruption from the proposed transaction making it more difficult to conduct business as usual or maintain relationships with customers, employees or suppliers; and the calculations of, and factors that may impact the calculations of, the acquisition price in connection with the proposed merger and the allocation of such acquisition price to the net assets acquired in accordance with applicable accounting rules and methodologies. Additional information and other factors are contained in Alkermes’ filings with the Securities and Exchange Commission, including Alkermes’ Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and other SEC filings, which are available at the SEC’s web site http://www.sec.gov. Alkermes disclaims any obligation to update and revise statements contained in these materials based on new information or otherwise.

In connection with the proposed merger, Alkermes plc will file with the SEC a registration statement on Form S-4 that will include a preliminary prospectus regarding the proposed merger and Alkermes will file with the SEC a proxy statement in respect of the proposed merger. After the registration statement has been declared effective by the SEC, a definitive proxy statement/prospectus will be mailed to Alkermes’ stockholders in connection with the proposed merger.
