ChipMOS TO REPURCHASE 12.2% OWNERSHIP FROM ThaiLin

HSINCHU, November 21, 2013 /PRNewswire-FirstCall/ -- ChipMOS TECHNOLOGIES (Bermuda) LTD. ("ChipMOS" or the "Company") (Nasdaq: IMOS), an industry leading provider of outsourced semiconductor assembly and test services, today announced that its Board of Directors has approved the repurchase of 12.2% ownership position in ChipMOS from the Company's subsidiary, ThaiLin Semiconductor Corporation ("ThaiLin"). Following the Board's approval, a Share Purchase Agreement was executed by ChipMOS and ThaiLin for the Company's repurchase of the 4.1 million shares held by ThaiLin.

The repurchase of the shares is expected to be consummated at two closings (the "Closings"). The repurchase of a portion of the shares (2,000,000 shares) is expected to take place on or around November 26, 2013 (the "First Closing Date"). The second closing for the remaining shares (2,093,705 shares) is expected to take place on or before January 31, 2014 (the "Second Closing Date").

The purchase price of the shares at each of the Closings will be determined by the arithmetic mean of the closing prices of the Company's Common Stock traded on the NASDAQ over the twenty (20) consecutive trading days prior to the preceding fifth day of each of the First Closing Date and the Second Closing Date multiplied by zero point nine three (0.93), reflecting a seven percent (7%) discount. Each of the Closings will be subject to the purchase price of the shares falling within a range of US$13.00 per share to US$19.92 per share.

The Company's outstanding share count is expected to remain approximately 30 million after the consummation of the Closings because the 4.1 million shares held by ThaiLin subject to the sale and repurchase have been treated as treasury shares and not included in the Company's share count.

S.J. Cheng, Chairman and Chief Executive Officer of ChipMOS, said, "This is another significant step forward for us in our efforts to streamline our corporate structure. The benefits of our successful business execution and strategic planning are clearly seen in our strong financial results and momentum. We continue to focus on both near and long-term initiatives to help secure the Company's future and to help increase the valuation and return for shareholders."

Furthermore, upon the advice of the Company's outside legal counsel, the Board of Directors agreed to cancel the Company's existing US$7.5 million repurchase program, which had been in place for the repurchase of the Company's publicly traded common shares on the NASDAQ Stock Market. The Board intends to review the Company's repurchase options related to common shares traded on the NASDAQ Stock Market upon completion of both Closings.
