S.J. Cheng, Chairman and Chief Executive Officer of ChipMOS, said, "Our 2Q10 revenue was up 22.5% from the first quarter and was 53.4% higher on a year over year basis. The substantial revenue growth was across all product segments and reflects the successful execution of our business strategy. We have expanded business with existing customers, built key new accounts and continue to manage in the upturn. Our DRAM and LCD driver businesses were both up strongly in Q2. DRAM benefitted from robust demand of both niche and commodity markets. Our LCD driver business benefitted from strong customer demand, termination of price discounts, and additional revenue brought by new capacity added with our SPIL deal. Our flash and mixed-signal businesses were also up but in the low single digits compared to Q1."

S.K. Chen, Chief Financial Officer of ChipMOS, said, "We continue to closely manage our operating expenses and keep spending as low as possible, while providing our global customer base with the highest possible quality and service that they rely on us for. This control combined with the significant increase in revenue drove 2Q10 gross margin improvement to 5.2%. We are targeting further improvements and expect a trend to historical margin levels in future quarters."

Third Quarter 2010 Outlook
Mr. Cheng continued, "Looking into the third quarter, we currently expect revenue to increase 4% to 10% compared to the second quarter 2010, with revenue growth primarily from LCD and flash businesses. We currently expect gross margin on a consolidated basis for the third quarter of 2010 to be in the range from 5% to 11%. The improvement in gross margin compared to the second quarter is primarily due to growth in revenue and product mix adjustment under fully utilized assembly manufacturing."

"We feel very comfortable about our business, progress, capacity and outlook. End market demand remains very robust in our core DRAM and LCD driver businesses. Our efforts to diversify our customer base have clearly worked and we continue to gain momentum. We are also seeing additional demand from the resumption of business activity with Spansion. We continue to move forward with our financial structure improvement efforts, and ample capacity to satisfy existing customer demand and new opportunities we are pursuing."
