Hsinchu, Taiwan, April 12, 2013 - ChipMOS TECHNOLOGIES (Bermuda) LTD. ("ChipMOS" or the "Company") (Nasdaq: IMOS) today announced that Gre Tai Securities Market ("GTSM") has approved the initial listing of its subsidiary ChipMOS TECHNOLOGIES INC., a Taiwan corporation ("ChipMOS Taiwan") on Taiwan's emerging stock board, with trading expected to begin on April 19, 2013 under the proposed stock ticker 8150. ChipMOS will continue to trade on NASDAQ under the ticker "IMOS", with no impact to or action required by existing stockholders.

The Company and ChipMOS Taiwan, with the assistance of its underwriters, Yuanta Securities Company, Limited and Capital Securities Corp., will continue to work towards satisfying eligibility requirements for listing ChipMOS Taiwan on the Taiwan Stock Exchange ("TSE") in the second quarter of 2014. Whether requirements can be satisfied for the continued listing on Taiwan's emerging stock board or the initial listing on the TSE depends in part on market conditions and other factors not within the control of the Company or ChipMOS Taiwan, including needed regulatory approvals. Even if ChipMOS Taiwan receives these approvals, it does not guarantee it will be able to satisfy other requirements. For these reasons there can be no assurance that ChipMOS Taiwan's shares will continue to trade on Taiwan's emerging stock board or that ChipMOS Taiwan will be listed on the TSE.

The details concerning Company's Board of Directors approval of listing plans for ChipMOS Taiwan were announced in a press release issued by the Company on March 18, 2013.

S.J. Cheng, Chairman and Chief Executive Officer of ChipMOS, said, "This is another important step forward for us in our plan to both streamline our corporate structure and to further enhance our global profile to the benefit of ChipMOS and our investors."
