The Company expects unaudited gross margin on a consolidated basis for the third quarter of 2012 to be approximately 18.5%, as compared to original guidance for approximately 12% to 18%, increased from the gross margin of 12.8% for 2Q'12 and 8.6% for 3Q'11.

ChipMOS' September 2012 and third quarter unaudited consolidated revenues and gross margin included revenues and operating results of ChipMOS TECHNOLOGIES INC., ChipMOS U.S.A., Inc., MODERN MIND TECHNOLOGY LIMITED and its wholly-owned subsidiary ChipMOS TECHNOLOGIES (Shanghai) LTD., and ThaiLin Semiconductor Corp.

Fourth Quarter of 2012 Business Outlook

The Company expects consolidated revenue for the fourth quarter of 2012 to be approximately flat to 5% lower, as compared to the third quarter of 2012, reflecting continued growth in its LCD driver and flash memory testing businesses, offset by continued broader softness in the memory market, which is decreasing the Company's commodity DRAM assembly business.  The Company expects gross margin on a consolidated basis for the fourth quarter of 2012 to be in the range of approximately 14% to 19%.
