The unaudited consolidated financial results of ChipMOS for the fourth quarter ended December 31, 2009 included the financial results of ChipMOS TECHNOLOGIES INC., ChipMOS U.S.A., Inc., ChipMOS TECHNOLOGIES (H.K.) Limited, MODERN MIND TECHNOLOGY LIMITED and its wholly-owned subsidiary ChipMOS TECHNOLOGIES (Shanghai) LTD., and ThaiLin Semiconductor Corp.

S.J. Cheng, Chairman and Chief Executive Officer of ChipMOS, said, "In the past year, we are proud of the numerous steps taken to improve our financial strength and business structure. By working with major creditors and investors we are moving forward in a much better position with the stronger footing needed for long-term success. We have also made impressive progress in diversifying our customer base and revenue mix. As a result, we ended 2009 on a positive note, with 4Q09 revenue increasing 7.2% compared to 3Q09 and increasing 17.6% compared to 4Q08. Growth was led by our DRAM business, which was up around 37% in 4Q09 compared to the also strong 3Q09. Demand came from both commodity and niche markets. Weakness in our LCD driver business from September continued into November due to a channel inventory adjustment. In December, we started to see indications of a recovery in LCD driver market demand, reflecting a capacity shortage and ASP recovery. Revenue in both our flash and mixed-signal businesses was down about 4% and 5% respectively in 4Q09 compared to 3Q09."

S.K. Chen, Chief Financial Officer of ChipMOS, said, "CapEx for the full year 2009 was US$108.9 million. The breakdown of CapEx for the fourth quarter was 3% for assembly, 96% for testing and 1% for LCD driver IC capacities. Of the US$108.9 million in CapEx, US$84.5 million occurred in the fourth quarter 2009. Of the US$84.5 million, US$73.8 million in CapEx was recognized under the revised lease program as disclosed on Nov 9, 2009. The US$73.8 million of CapEx was not, however, an immediate cash outflow in the fourth quarter. Rather, the payment will be spread out from Q4 2009 to Q4 2013. We expect to see the benefit in 2010 of the considerable financial restructuring we accomplished in 2009. Adding to our confidence is our healthy balance sheet and improving business conditions."

First Quarter 2010 Outlook
Mr. Cheng continued, "While 2009 was clearly a challenging year for ChipMOS, we turned many of the negatives into positives. We expect to benefit from our customer and revenue mix diversification, combined with the more favorable broader market environment. We also expect to further strengthen our balance sheet given our improving business and progress in collecting on prior customer receivables. Given our more positive outlook, we recently announced a strategic transaction with SPIL to acquire its LCD driver assembly and test, and DRAM test production lines. This is another positive move for us in the face of the ongoing LCD backend capacity shortage that will add capacity at a minimum cost. Overall, considering customer forecasts and the market environment, we currently expect that first quarter revenue will be flat to having growth in the single digit percentage, as compared to the fourth quarter 2009. Finally, we currently expect gross margin on a consolidated basis for the first quarter of 2010 to be in the range of approximately -7% to -11%. The improvement in gross margin compared to Q4 is primarily due to the decreased equipment rental fee under the revised lease program as we announced on November 9, 2009."
