HSINCHU, Taiwan, Sept. 24 /Xinhua-PRNewswire-FirstCall/ -- Macronix International Co., Ltd. (Nasdaq: MXIC; TSEC: 2337) announced on September 21, 2007 that it plans to delist its American Depositary Shares (ADS) from Nasdaq, to terminate its American Depositary Receipts (ADR) program and to end the registration of its shares under the US Securities and Exchange Act of 1934, as amended (Exchange Act). Macronix is continuously seeking to optimize its costs and believes that the ongoing costs of its ADR program are not economically justified by the benefits, given the relatively small proportion of trading that takes place in the form of ADRs. Accordingly, Macronix has decided to delist and deregister its ADRs. Macronix expects that its listing on Nasdaq will effectively be terminated on or after October 29. As regards deregistration, Macronix plans to file Form 15F with the SEC on or after October 29. Immediately upon filing Form 15F, Macronix will no longer have any obligation to file annual and other reports with the SEC. Macronix expects that deregistration will become effective 90 days after the filing of Form 15F. A notification will be sent to ADR holders setting forth the termination of the ADR program. Prior to the delisting holders can elect to sell their ADSs over Nasdaq or they are entitled to exchange their ADRs with the Bank of New York, as depositary, for underlying Macronix common shares. Following the delisting during a period of 12 months holders are still entitled to exchange their ADRs for underlying Macronix common shares. At the end of this period any remaining shares underlying the ADRs will be sold, the proceeds of sale will be held for a time by the depositary and the ADRs will represent only the right to receive the cash proceeds of sale of the underlying shares. The dividend record date remains unchanged as September 21, 2007. For further information, please refer to the Investor Information section of the Macronix website http://www.macronix.com/ . Macronix will further develop its business operations in the US, but wishes to concentrate its trading volume at Taiwan Stock Exchange Corporation (TSEC), which reduces complexity and therefore costs. Macronix considers US investors an important part of its investor base and will maintain its relationship with US investors. Macronix will make English translations of its annual reports, financial statements and other press releases available on its web site. Following the delisting from Nasdaq, Macronix's common shares will continue to trade on TSEC. The Company has not arranged for listing and/or registration of the Company's securities on another US securities exchange or for quotation of the Company's securities on any other quotation medium in the United States.
