S.J. Cheng, Chairman and Chief Executive Officer of ChipMOS, said, "We are pleased to report that we exited 2011 with increased momentum in our revenue and profitability growth, an improved financial position, and positive business prospects.  We believe that our strategic focus on higher revenue and higher margin opportunities helped drive this growth, and helped us to further strengthen our balance sheet.   We ended 2011 with US$243.1 million in cash and cash equivalents, after having reduced total debt by US$134.5 million in 2011.  We believe that we have firmly established ChipMOS as one of the industry's most important outsourced semiconductor assembly and testing services companies.  We are aggressively focused on building on our position in key markets, including our LCD assembly and test business and are highly optimistic for the Company's prospects in 2012.  We continue to expect revenue growth of approximately 10% in 2012."

S.K. Chen, Chief Financial Officer of ChipMOS, said, "Gross profit for the full year 2011 increased to US$52.8 million compared to US$19.0 million in 2010.  For the full year 2011, our blended utilization rate was 75%, with an increase to 72% in 4Q11 compared to 68% in the same period 2010.  The improvement reflects the considerable growth in our LCD driver segment, which was up 25% for the full year 2011 compared to 2010, representing 22% of total revenue in 2011 compared to 19% in 2010. The growth in our bumping segment was also significant, which was up 48% for the full year 2011 compared to 2010, representing 13% of total revenue in 2011 compared to 9% in 2010.  Our balance of cash and cash equivalents was improved to US$243.1 million as of December 31, 2011, compared to US$236.0 million as of December 31, 2010.  We reduced the Company's total debt by US$134.5 million in 2011, resulting in an improvement of our net debt to equity ratio to 22.6% as of December 31, 2011 compared to 66.8% at the end of 2010.  Finally, we have repurchased approximately 47,100 shares valued at approximately US$362.0 thousand under our share repurchase program as of March 15, 2012.  With a continued disciplined business and capital expense strategy, we expect to generate positive free cash flow for the full year 2012."

First Quarter 2012 Outlook

Mr. Cheng continued, "We expect continued strength in our LCD driver business but not enough in the first quarter to offset typical seasonality and expected softness in our DRAM and flash testing business.  As a result, we currently expect revenue in the first quarter of 2012 to be approximately flat-to-down in the single digits as compared to the fourth quarter of 2011, with gross margin on a consolidated basis in the range of approximately 4.0% to 9.0%.  We remain very optimistic about our business prospects for 2012 and longer-term based on existing customer forecasts.  To meet higher customer demand levels in our LCD driver business, our Board has approved a strategic investment to build a 16,000 wafer/month capacity of 12-inch gold bump manufacturing facility and an 8,000 wafer/month capacity of 12-inch copper bump manufacturing facility.  Demand for copper bumping capabilities continues to increase given the cost benefit to customers. We expect to have the new capacity operating by the second half of 2012.  This will allow us to capture additional growth opportunities in related LCD driver IC and WLCSP (Wafer Level Chip Scale Package) business, smartphone and tablet PC applications."

- FINANCIAL TABLES FOLLOW BELOW -

Use of Non-GAAP Financial Information
To supplement our consolidated income statement (unaudited) for the three months and the year ended Dec. 31, 2011 on a US GAAP basis, the Company uses a non-GAAP measure of net income (loss), which is US GAAP net income (loss) adjusted to exclude two non-cash items referred to as special items. The two non-cash items excluded are changes in the fair value of the embedded derivative liabilities and amortization of discount on convertible notes. These items are considered by the management to be outside of the Company’s core operating results. For example, changes in the fair value of the embedded derivative liabilities relate heavily to the Company’s stock price, interest rate and volatility, all of which are difficult to predict and outside of the control of the Company and its management.

For these reasons, management uses non-GAAP adjusted measures of net income (loss) and non-GAAP net income (loss) per
share to evaluate the performance of our core businesses and to estimate future core performance. In addition, this information
facilitates our management’s internal comparisons to our historical operating results as well as to the operating results of our
competitors.

The Company’s management finds these supplemental non-GAAP measures to be useful, and we believe these non-GAAP
measures are useful to investors in enabling them to perform additional analyses of past, present and future operating
performance and as a supplemental means to evaluate our core operating results. However, readers are reminded that non-GAAP
numbers are merely a supplement to, and not a replacement for, US GAAP financial measures. They should be read in
conjunction with the US GAAP financial measures. It should be noted as well that our non-GAAP information may be different from
the non-GAAP information provided by other companies.
