This statement contains “forward-looking statements” within the meaning of Section 27A of the United States Securities Act of 1933, as amended, and Section 21E of the United States Securities Exchange Act of 1934, as amended, including statements regarding ASE’s or HoldCo’s future results of operations and business prospects. Although these forward-looking statements, which may include statements regarding the expected completion of the proposed combination between ASE and Siliconware Precision Industries Co., Ltd. (“SPIL”) and any benefits or synergies of the proposed combination, as well as ASE’s or HoldCo’s (if established) future results of operations, financial condition or business prospects, are based on certain assumptions made by ASE or HoldCo (if established) based on management’s experience, perception of historical trends and technical analyses, current conditions, anticipated future developments and other factors believed to be appropriate and reasonable by management as well as information from other sources ASE’s management believes to be reliable, you should not place undue reliance on these forward-looking statements, which apply only as of the date of this statement. The words “will,” “potential,” “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “may,” “could,” “project,” or their negatives, and other similar expressions or statements, as they relate to ASE or HoldCo (if established), are intended to identify these forward-looking statements, although not all forward-looking statements contain such identifying words. These statements discuss future expectations, identify strategies, contain projections of results of operations of ASE’s or HoldCo’s (if established) financial condition, or state other forward-looking information. Known and unknown risks, uncertainties and other factors could cause the actual results to differ materially from those contained in any forward-looking statement. These include risks and uncertainties that may affect the proposed combination with SPIL, the satisfactory completion of due diligence by the parties, the ability of the parties to negotiate and enter into a definitive agreement and, if such an agreement is entered into, the satisfaction of the conditions contained in the definitive agreement, any delay or inability to obtain necessary approvals or consents from third parties and the ability of the parties to realize the anticipated benefits from the proposed business transaction. ASE cannot guarantee that its expectations expressed in these forward-looking statements will turn out to be correct. ASE’s or HoldCo’s (if established) actual results could be materially different from and worse than those expectations. For a discussion of important risks and factors that could cause ASE’s or HoldCo’s (if established) actual results to be materially different from its expectations, please see the documents we file from time to time with the U.S. Securities and Exchange Commission (“U.S. SEC”), including ASE’s 2016 Annual Report on Form 20-F filed on April 21, 2017. Any forward-looking statement speaks only as of the date on which such statement is made and ASE undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law.
