Diodes Incorporated Reports Third Quarter 2008 Financial Results

Achieves Record Quarterly Revenue of $134.0 Million

Dallas, Texas — November 6, 2008 —— Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today reported financial results for the third quarter ended September 30, 2008. In the third quarter, Diodes made the required preliminary estimate of the purchase accounting impact of the Zetex acquisition in its GAAP financials. The impact of the purchase accounting is identified for comparison purposes.

Financial and Business Highlights:

• Revenue increased 27 percent to a record $134.0 million, including a full quarter of Zetex results;

• GAAP EPS of ($0.07), including $14.8 million, or $0.34 per share in non-cash purchase price accounting charges related to the Zetex acquisition;

• Adjusted Non-GAAP EPS, excluding purchase price adjustments and SFAS 123R stock option expense, of $0.29;

• Cash generated from operations of $13.5 million.

Revenue for the third quarter of 2008 increased 27.3 percent to a record $134.0 million as compared to $105.3 million reported in the third quarter of 2007 and increased 15.5 percent when compared to $116.0 million reported in the second quarter of 2008, which included one month of Zetex results.

Gross profit for the third quarter of 2008, which included $5.4 million of non-cash purchase price adjustments related to the Zetex acquisition, was $38.1 million, or 28.4 percent of revenue. Excluding the non-cash purchase price adjustments, gross margin was 32.5 percent as compared to 34.1 percent in second quarter of 2008 with the decrease primarily due to lower capacity utilization in manufacturing operations as a result of market conditions and a reduction of finished goods inventory.

Commenting on the quarter, Dr. Keh-Shew Lu, President and CEO of Diodes Incorporated, said, “The third quarter represented our first full quarter of operations with Zetex, and our integration efforts remain on track and have been progressing well throughout the quarter. Due to current and future expectations for the overall economy, we have identified a number of expense reduction opportunities to optimize our cost structure across the organization. These initiatives include accelerating our plan to integrate the Zetex products into our manufacturing facilities, reducing manufacturing process and raw material costs as well as realigning our product development and wafer fabrication organizations, including a shut-down of our 4-inch fab line in Oldham, headcount reductions at our wafer fab in Kansas City and a hiring freeze at all other locations.”

Third quarter GAAP net loss was $2.9 million, or ($0.07) per share, which included $14.8 million in net purchase price adjustments, consisting of a one-time non-cash $5.2 million inventory charge, a $0.2 million non-cash depreciation expense, a $7.9 million one-time non-cash write-off of acquired in-process research and development charges and $1.6 million in amortization of acquisition related intangible assets. Excluding the acquisition charges, adjusted non-GAAP net income was $11.9 million, or $0.27 per share.

Adjusted net income computed on a non-GAAP basis for the third quarter of 2008, which excluded approximately $600,000 of SFAS 123R net stock option expenses and the acquisition charges, was $12.5 million, or $0.29 per diluted share. Beginning in the fourth quarter of 2008, Diodes intends to change its reporting policy regarding SFAS 123R net stock option expenses, which will be included in adjusted net income in future quarters.

As of September 30, 2008, Diodes had approximately $82.7 million in total cash, $285 million in long-term investments (representing $320 million of auction rate securities at par value), $201 million in working capital and $400 million in long-term debt (including the convertible notes).

Business Outlook

Dr. Lu concluded, “For the fourth quarter of 2008, we expect market uncertainty to continue with an ongoing decrease in global demand, in particular for the consumer and computer markets, and estimate revenue to decline sequentially between 12 and 20 percent. We expect GAAP earnings per share to range between $0.07 and $0.13, which includes approximately $0.03 of purchase price accounting adjustments. Non-GAAP earnings per share is expected to range between $0.10 and $0.16, which includes SFAS 123R stock option expenses. Overall, we continue to execute on the strategy that has proven successful for Diodes over the years. We are confident that our acquisition of Zetex will continue to add significant value to our business as we further capitalize on the cross-selling opportunities and diversification benefits that the acquisition offers our Company. Although the economy creates a more challenging environment for all businesses, we remain focused on our growth strategy. We will continue to invest in research and development to drive organic growth and believe that over the long-term Diodes is in a better position for growth than ever before. Our design activity has never been higher, which we believe positions the Company for accelerated growth as the economy improves.”

ADJUSTED NET INCOME

This measure consists of generally accepted accounting principles, or GAAP, net income, which is then adjusted solely for the purpose of adjusting for restructuring costs, stock option expense, purchase accounting impact on earnings and other adjustments, as discussed below. Excluding the restructuring costs, in-process research and development (“IPR&D”) expense, inventory valuations impact on gross profit and margins, stock option expense and other adjustments provides investors with a better depiction of the Company’s operating results and provides a more informed baseline for modeling future earnings expectations. Excluding the amortization of acquisition-related intangible assets and depreciation impact on gross profit and margins allows for comparison of our current and historic operating performance. We exclude the above items to evaluate our operating performance, to develop budgets, to determine incentive compensation awards and to manage cash expenditures. Presentation of the above non-GAAP measures allows investors to review the Company’s results of operations from the same view point as our management and Board of Directors. We have historically provided similar non-GAAP financial measures to provide investors an enhanced understanding of our operations, facilitate investors’ analyses and comparisons of our current and past results of operations and provide insight into the prospects of our future performance. We also believe that the non-GAAP measures are useful to investors because they provide additional information that research analysts use to evaluate semiconductor companies. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results and may differ from measures used by other companies. We recommend a review of net income on both a non-GAAP basis and GAAP basis be performed to get a comprehensive view of our results. We provide a reconciliation of adjusted net income to GAAP net income below.

Detail of non-GAAP adjustments:

Restructuring Costs — The Company has recorded various restructuring charges to reduce our cost structure to enhance operating effectiveness and improve profitability. These restructuring activities impacted different functional areas of our operations in different locations and were undertaken to meet specific business objectives in light of the facts and circumstances at the time of each restructuring event. These charges include costs related to the consolidation of our analog wafer probe and final test operations from Hsinchu, Taiwan to our manufacturing facilities in Shanghai, China which primarily consisted of termination and severance costs and impairment of fixed assets. These restructuring charges are excluded from management’s assessment of our operating performance. We believe that the exclusion of the non-recurring restructuring charges provides investors an enhanced view of the cost structure of our operations and facilitates comparisons with the results of other periods that may not reflect such charges or may reflect different levels of such charges.

Purchase Accounting Impact on Earnings:

• Amortization of acquisition-related intangible assets — The Company has excluded the amortization of Zetex acquisition-related intangible assets including developed technologies, customer relationships and trade name from its non-GAAP results. The fair value of the acquisition-related intangible assets, which was allocated to the assets through purchase accounting, is amortized using straight-line methods which approximate the proportion of future cash flows estimated to be generated each period over the estimated useful lives of the applicable assets. We believe that the exclusion of the amortization expense of acquisition-related assets is appropriate as a significant portion of the purchase price for the acquisition was allocated to the intangible assets that have short lives and exclusion of the amortization expense allows comparisons of operating results that are consistent over time for both the Company’s newly acquired and long-held businesses. In addition, we exclude the amortization expense as there is significant variability and unpredictability across companies with respect to this expense.

• IPR&D expense - The Company has excluded the non-recurring IPR&D expense, which is non-cash and related to the acquisition of Zetex, from its non-GAAP results. Under GAAP, the Company immediately expensed all the acquired IPR&D as it had not yet reached technological feasibility and had no alternative further use as of the date of acquisition. This adjustment to R&D expense is not recurring in nature and as such we believe that the exclusion of this adjustment provides investors useful information facilitating an understanding of earnings as this impact reduces our earnings to amounts lower than we have historically achieved and expect to achieve in the future.

• Inventory valuations and depreciation adjustments - The Company has excluded the $5.4 million inventory valuation and depreciation adjustments. Under GAAP, the Company adjusted the inventory acquired from Zetex to account for the reasonable profit allowance for the selling effort on finished goods inventory and the reasonable profit allowance for the completing and selling effort on the work—in-process inventory. This non-cash adjustment to inventory is not recurring in nature and as such we believe that the exclusion of this adjustment provides investors useful information facilitating an understanding of our gross profit and margins as this impact reduces our gross profit and margins to percentages lower than we have historically achieved and expect to achieve in the future. The exclusion of the depreciation expense allows comparisons of operating results that are consistent over time for both the Company’s newly acquired and long-held businesses. In addition, we exclude the deprecation expense as there is significant variability and unpredictability across companies with respect to this expense.

Other Adjustments — The Company incurred a one-time non-cash currency hedge loss related to the Zetex acquisition in the second quarter of 2008. This currency hedge loss is excluded from management’s assessment of our operating performance for the first nine months of 2008. We believe that the exclusion of the non-recurring currency hedge loss provides investors an enhanced view of the one-time other adjustments that the Company may incur from time to time and facilitates comparisons with the results of other periods that may not reflect such charges.

Stock Option Expense — Historically, the Company excluded the non-cash stock option expense adjustments as it provided investors with a better depiction of the Company’s operating results and provides a more informed baseline for modeling future earnings expectations. Upon further review of its non-GAAP adjustments, the Company has concluded it will no longer adjust for stock option expense as it is recurring in nature starting in the fourth quarter of 2008.

ADJUSTED EARNINGS PER SHARE

This non-GAAP financial measure is the portion of the Company’s GAAP net income assigned to each share of stock, excluding restructuring costs, stock option expense, purchase accounting impact on earnings and other adjustments, as described above. Excluding the restructuring costs, IPR&D expense, inventory valuations impact on gross profit and margins, stock option expense and other adjustments provides investors with a better depiction of the Company’s operating results and provides a more informed baseline for modeling future earnings expectations, as described in further detail above. Excluding the amortization of acquisition-related intangible assets and depreciation impact on gross profit and margins allows for comparison of our current and historic operating performance, as described in further detail above. This non-GAAP measure should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results and may differ from measures used by other companies. We recommend a review of diluted EPS on both a non-GAAP basis and GAAP basis be performed to get a comprehensive view of our results. Information on how these share calculations are made is included in the table above.

DIODES INCORPORATED AND SUBSIDIARIES
CONSOLIDATED RECONCILIATION OF NET INCOME (LOSS) TO EBITDA

EBITDA represents earnings before net interest expense, income tax provision, depreciation and amortization. Our management believes EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties, such as financial institutions in extending credit, in evaluating companies in our industry and provides further clarity on our profitability. In addition, our management uses EBITDA, along with other GAAP measures, in evaluating our operating performance compared to that of other companies in our industry because the calculation of EBITDA generally eliminates the effects of financing, operating in different income tax jurisdictions, and accounting effects of capital spending, including the impact of our asset base, which can differ depending on the book value of assets and the accounting methods used to compute depreciation and amortization expense. EBITDA is not a recognized measurement under generally accepted accounting principles, or GAAP, and when analyzing our operating performance, investors should use EBITDA in addition to, and not as an alternative for, income from operations and net income, each as determined in accordance with GAAP. Because not all companies use identical calculations, our presentation of EBITDA may not be comparable to similarly titled measures of other companies. Furthermore, EBITDA is not intended to be a measure of free cash flow for our management’s discretionary use, as it does not consider certain cash requirements such as a tax and debt service payments.
