Forward-Looking StatementsThis press release includes "forward-looking statements" made under the provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements, other than statements of historical fact, regarding, without limitation, the completion, timing and size of Achillion's proposed public offering and the use of proceeds therefrom. In some cases, words such as "will," "expect" or other comparable words identify forward-looking statements. Actual results, performance or experience may differ materially from those expressed or implied by any forward-looking statement as a result of various important factors, including without limitation risks and uncertainties relating to Achillion's business and financial condition, general market conditions and the satisfaction of customary closing conditions associated with the proposed public offering. Factors that may cause such a difference include, without limitation, risks and uncertainties related to whether or not Achillion will be able to raise capital through the sale of shares of common stock, the final terms of the proposed offering, market and other conditions, the satisfaction of customary closing conditions related to the proposed public offering and the impact of general economic, industry or political conditions in the United States or internationally. Risks and uncertainties that Achillion faces are described in greater detail under the heading "Risk Factors" in its 2012 Annual Report on Form 10-K and its subsequent SEC filings, as well as other filings that it makes with the SEC. As a result of the risks and uncertainties, the results or events indicated by any forward-looking statement may not occur. Achillion cautions you not to place undue reliance on any forward-looking statement.
