ChipMOS UPWARDLY REVISES Q3 2009 GUIDANCE;

EXPECTS 13%-15% SEQUENTIAL REVENUE GROWTH

Hsinchu, Taiwan, October 2, 2009 – ChipMOS TECHNOLOGIES (Bermuda) LTD. (“ChipMOS” or the “Company”) (NASDAQ: IMOS) today announced upwardly revised guidance for Q3 2009. The Company now expects revenue growth of 13% to 15% in the Q3 2009 compared to Q2 2009. This upwardly revised guidance compares to the Company’s previous outlook for a high single digit percentage revenue growth in the Q3 2009 compared to Q2 2009. The improvement in Q3 revenue guidance is primarily due to better than expected results in the Company’s DRAM and mixed-signal/logic businesses.
