Hsinchu, Taiwan, May 13, 2009 - ChipMOS TECHNOLOGIES (Bermuda) LTD. ("ChipMOS" or the "Company") (NASDAQ: IMOS) today reported unaudited consolidated financial results for the first quarter ended March 31, 2009.  All U.S. dollar figures in this release are based on the exchange rate of NT$33.87 against US$1.00 as of March 31, 2009.

Net revenue on a US GAAP basis for the first quarter of 2009 was NT$2,280.7 million or US$67.3 million, a decrease of 52.3% from NT$4,779.0 million or US$141.1 million for the same period in 2008 and a decrease of 25.3% from NT$3,052.6 million or US$90.1 million in the fourth quarter of 2008.

Net loss attributable to ChipMOS on a US GAAP basis for the first quarter of 2009 was NT$1,984.0 million or US$58.6 million, and NT$23.99 or US$0.71 per basic common share, compared to net loss attributable to ChipMOS of NT$5,838.6 million or US$172.4 million, and NT$69.54 or US$2.05 per basic common share, for the fourth quarter of 2008.  Net loss attributable to ChipMOS under US GAAP includes amortization of discount on convertible notes of NT$26.3 million or US$0.8 million for the first quarter of 2009 and non-cash gains for change in the fair value of the embedded derivative liabilities of NT$8.6 million or US$0.3 million and amortization of discount on convertible notes of NT$27.9 million or US$0.8 million for the fourth quarter of 2008. Excluding the above special items regarding the convertible notes, non-GAAP adjusted net loss attributable to ChipMOS for the first quarter of 2009 was NT$1,957.7 million or US$57.8 million, and NT$23.67 or US$0.70 per basic common share, compared to non-GAAP adjusted net loss attributable to ChipMOS of NT$5,819.3 million or US$171.9 million, and NT$69.31 or US$2.05 per basic common share in the fourth quarter of 2008.

The unaudited consolidated financial results of ChipMOS for the first quarter ended March 31, 2009 included the financial results of ChipMOS TECHNOLOGIES INC., ChipMOS Japan 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, "Our results in the first quarter reflect the continued severe downturn impacting the global economy and the semiconductor industry.  Declines in our revenues, margin and profitability directly resulted from such market weakness.  With that said, we have successfully navigated through prior industry downturns.  We are taking the necessary steps to strengthen our financial position and to ensure the credit-worthiness of our customers.  While we believe our implementation of a cash on delivery policy for certain customers resulted in lower orders, we are confident this is the prudent action to take in order to help minimize potential bad debt issues.  Other measures include receipt of loan repayment extensions and modifications announced on April 15."

S.K. Chen, Chief Financial Officer of ChipMOS, said, "We continue to actively manage our financial structure as we navigate through the current downturn.  In April, we secured loan repayment extensions and modifications that deferred about 77% of the 2009 loan repayment obligation of ChipMOS.  We also achieved further reductions in operating expenses, with additional action taken in general and administrative and sales and marketing.  We will continue to evaluate cost reduction opportunities wherever we have control, while maintaining the high quality customer support and R&D effort ChipMOS is known for.  Our goal is to maintain a lean cost structure capable of supporting the improving customer demand levels we expect later this year based on customer forecasts."

Second Quarter 2009 Outlook
Mr. Cheng continued, "While the global economic situation remains tentative, we are seeing some signs of improvement.  Our view is that the first quarter may prove to be the bottom of the current down cycle.  We are starting to see muted signs of inventory rebuilding and slightly encouraging end product demand.  Our optimism is extremely cautious, however, as forecasts remain in flux, customer demand remains conservative and visibility remains low.  While we expect continued challenges in our flash business, we expect limited improvement in our DRAM testing business, with potential gains in our LCD driver business due to demand for cell phones, notebook PC, and LCD TVs.  We also expect to benefit from improvement in our mixed-signal testing business compared to the first quarter of 2009."

Considering the overall market situation and customer forecasts, we currently expect that second quarter of 2009 revenue to be in the range of approximately US$87 million to US$90 million, which would represent an increase of 29% to 34% as compared to the first quarter of 2009. The revenue forecast is based on the exchange rate of NT$33.87 to the USD as of March 31, 2009. The reported second quarter revenue in US dollars may vary from our guidance due to a different exchange rate at the end of the second quarter. Finally, we currently expect gross margin on a consolidated basis for the second quarter of 2009 to be in the range of approximately negative 29% to negative 34% primarily due to the impact of low utilization rate in DRAM final test capacity.

We believe that the subsidiary loan repayment schedule extension, as announced on April 15, would significantly improve our cash position and reduce our net current liabilities. In addition, we are in negotiations with our bank creditors to obtain a waiver for potential covenant breaches under our contract of syndication loan. We have also approached holders of our convertible bonds due 2009 with a view to re-negotiating the terms of the bonds. These are key aspects of our plans to address going concern risks. While there can be no assurance that the waiver will be obtained or the re-negotiation be successful, we believe that if obtained, the waiver of covenant breach and consent by bondholders will be significant additional steps toward accomplishing these plans.

RECONCILIATION OF US GAAP NET INCOME (LOSS) ATTRIBUTABLE TO CHIPMOS

Use of Non-GAAP Financial Information
To supplement our consolidated income statement (unaudited) for the three months ended Mar. 31, 2009 on a US GAAP basis, the Company uses a non-GAAP measure of net income (loss) attributable to ChipMOS, which is US GAAP net income (loss) attributable to ChipMOS 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) attributable to ChipMOS and non-GAAP earnings (loss) per share attributable to ChipMOS 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.
