Diodes Incorporated Reports Fiscal 2011 and Fourth Quarter Financial Results

Achieves Record Revenue for 2011 and 21 Consecutive Years of Profitability

Plano, Texas – February 8, 2012 – Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today reported its financial results for the fiscal year and fourth quarter ended December 31, 2011.

Year 2011 Highlights

Fourth Quarter Highlights

Commenting on the results, Dr. Keh-Shew Lu, President and Chief Executive Officer of Diodes Incorporated, stated, “I am very pleased to report that Diodes continued its growth during 2011 and achieved record revenue for the full year despite ongoing uncertainty in the global economy. This year also represented our 21^st consecutive year of profitability, which underscores the success of our profitable growth strategy. The broad market weakness that began in late second quarter continued to impact all of our market segments throughout the fourth quarter, but past design win momentum and new product initiatives enabled further market share gains. Although productivity and manufacturing efficiencies in our Shanghai facility have recovered to prior levels, gross margin

continues to be negatively impacted by the effects of the market softness, including increased pricing pressure, continued sales of lower margin commodity products and less than maximum utilization of manufacturing capacity, despite the increase in our finished goods inventory in advance of the Chinese New Year.”

“We are closely monitoring the market environment during the first quarter of 2012 and are continuing to delay capital investments, except for new product expansion and copper wire conversion. We have also slowed the pace of the building construction of our Chengdu facility and expect completion by the end of the second quarter of 2012. Increasing capacity at our Chengdu facility above the current pilot line level will depend upon market requirements and improvements in demand. In addition, we plan to maintain our operating expense controls. Overall, I believe we are better positioned than we were coming out of the 2009 downturn, which sets the stage for growth in 2012 as the market improves.”

Business Outlook

Dr. Lu concluded, “The first quarter is typically a seasonally down quarter for our business. However, we expect revenue to be better than the normal seasonal pattern due to improved distributor order rates in North America and Europe as well as the ramping of new projects for our products used in smartphones and tablets. As such, for the first quarter of 2012, we expect revenue to range between $138 million and $148 million, or flat plus or minus $5 million sequentially. We expect gross margin to be 25 percent, plus or minus 2.0 percent. Operating expenses are expected to remain approximately flat with fourth quarter on a dollar basis. We expect our income tax rate to range between 17 and 23 percent, and shares used to calculate GAAP EPS for the first quarter are anticipated to be approximately 47.2 million.”

Fiscal 2011

For the fiscal year 2011, revenue increased to a record $635.3 million, an increase of 3.6 percent over the $612.9 million in 2010. Gross profit was $193.7 million, or 30.5 percent of revenue, compared to $224.9 million, or 36.7 percent of revenue, in the prior year. GAAP net income was $50.7 million, or $1.09 per diluted share, compared to $76.7 million, or $1.68 per diluted share in 2010.

Non-GAAP adjusted net income for 2011 was $58.0 million, or $1.24 per diluted share, which excluded, net of tax, $3.9 million of non-cash interest expense related to the amortization of debt discount on the Convertible Senior Notes and $3.3 million of non-cash acquisition related intangible asset amortization costs, compared to non-GAAP adjusted net income of $82.9 million, or $1.82 per diluted share, in the prior year. The following is a summary reconciliation of GAAP net income to non-GAAP adjusted net income and per share data, net of tax (in thousands, except per share data):

See the tables below for further details of the reconciliation.

Included in fiscal 2011 GAAP and non-GAAP adjusted net income was approximately $8.9 million, net of tax, non-cash share-based compensation expense. Excluding this expense, both GAAP and non-GAAP adjusted diluted EPS would have increased by an additional $0.19 per diluted share, the same amount per diluted share by which share-based compensation affected GAAP and non-GAAP adjusted net income in 2010.

EBITDA, which represents earnings before net interest expense, income tax provision, depreciation and amortization, for fiscal 2011 was $130.5 million, compared to $156.4 million for fiscal 2010. For a reconciliation of GAAP net income to EBITDA (non-GAAP), see table below.

For the year ended December 31, 2011, net cash provided by operating activities was $61.7 million. In accordance with US GAAP, certain tax items that relate to the retirement of Convertible Senior Notes in the amount of negative $15 million have been recorded in cash flow from operations. Excluding these adjustments, adjusted cash flow from operations was $77 million. Net cash flow was a negative ($141.4) million due to the retirement of the Convertible Senior Notes. Free cash flow was a negative ($19.3) million, which was also negatively impacted $15 million by certain tax accounting adjustments related to the Convertible Senior Notes.

Fourth Quarter 2011

Revenue for the fourth quarter of 2011 was $143.3 million, a decrease of 12.5 percent over the $163.8 million in the fourth quarter of 2010, and a decrease of 10.8 percent from the $160.6 million in the third quarter of 2011. The decrease in revenue was due to a general market weakness across all market segments, including consumer, computing and communications markets.

Gross profit for the fourth quarter of 2011 was $35.5 million, or 24.8 percent of revenue, compared to $62.6 million, or 38.3 percent, in the fourth quarter of 2010 and $45.2 million, or 28.1 percent of revenue, in the third quarter 2011. The decline in gross profit margin was due primarily to a weak pricing environment and a sustained shift in product mix to lower margin products in an effort to maintain capacity utilization at the Company’s wafer fabs and Shanghai packaging facilities.

Fourth quarter 2011 GAAP net income was $3.1 million, or $0.07 per diluted share, compared to GAAP net income of $24.0 million, or $0.52 per diluted share, in the fourth quarter of 2010 and GAAP net income of $10.0 million, or $0.21 per diluted share, in the third quarter of 2011.

Non-GAAP adjusted net income for the fourth quarter of 2011 was $4.0 million, or $0.09 per diluted share, which excluded, net of tax, $0.9 million of non-cash acquisition related intangible asset amortization costs, compared to non-GAAP adjusted net income of $25.3 million, or $0.55 per diluted share, in the fourth quarter of 2010 and non-GAAP adjusted net income of $12.1 million, or $0.26 per diluted share, in the third quarter of 2011. The following is a summary reconciliation of GAAP net income to non-GAAP adjusted net income and per share data, net of tax (in thousands, except per share data):

See the tables below for further details of the reconciliation.

Included in fourth quarter 2011 GAAP and non-GAAP adjusted net income was approximately $2.4 million, net of tax, non-cash share-based compensation expense. Excluding share based compensation expense, both GAAP and non-GAAP adjusted diluted EPS would have increased by an additional $0.05 per share, the same amount per diluted share by which share-based compensation affected GAAP and non-GAAP adjusted net income in fourth quarter 2010.

EBITDA, which represents earnings before net interest expense, income tax, depreciation and amortization, for the fourth quarter of 2011 was $19.7 million, compared to $46.7 million for the fourth quarter of 2010 and $29.2 million for the third quarter of 2011. For a reconciliation of GAAP net income to EBITDA (non-GAAP), see the table below.

For the fourth quarter of 2011, net cash provided by operating activities was a negative ($3.4) million cash flow from operations and $4.6 million net cash flow. Excluding certain tax accounting adjustments related to the Convertible Senior Notes’ retirement, adjusted cash flow from operations was $12 million. Free cash flow was negative ($14.5) million, which was also negatively impacted $15 million by certain tax accounting adjustments related to the Convertible Senior Notes.

As of December 31, 2011, Diodes had approximately $130 million in cash and cash equivalents and working capital was approximately $317 million.

For the three months ended December 31, 2010:

Note: Included in GAAP and non-GAAP adjusted net income was approximately $2.1 million, net of tax, non-cash share-based compensation expense. Excluding this expense, both GAAP and non-GAAP adjusted diluted EPS would have increased by an additional $0.05 per share.

ADJUSTED NET INCOME (Non-GAAP)

This measure consists of generally accepted accounting principles (“GAAP”) net income, which is then adjusted solely for the purpose of adjusting for amortization of acquisition related intangible assets, amortization of debt discount, gain on sale of assets, impairment of long-lived assets and forgiveness of debt, as discussed below. Excluding gain on sale of assets, impairment of long-lived assets, and forgiveness of debt 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 amortization of debt discount allows for comparison of the Company’s current and historic operating performance. The Company excludes the above listed items to evaluate the Company’s 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 viewpoint as the Company’s management and Board of Directors. The Company has historically provided similar non-GAAP financial measures to provide investors an enhanced understanding of its operations, facilitate investors’ analyses and comparisons of its current and past results of operations and provide insight into the prospects of its future performance. The Company also believes 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. The Company recommends a review of net income on both a GAAP basis and non-GAAP basis be performed to get a comprehensive view of the Company’s results. The Company provides a reconciliation of GAAP net income to non-GAAP adjusted net income.

Amortization of acquisition related intangible assets – The Company excluded the amortization of its acquisition related intangible assets including developed technologies and customer relationships. 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. The Company believes the exclusion of the amortization expense of acquisition related assets is appropriate as a significant portion of the purchase price for its acquisitions 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, the Company excluded the amortization expense as there is significant variability and unpredictability across other companies with respect to this expense.

Amortization of debt discount – The Company excluded the amortization of debt discount on its 2.25% Convertible Senior Notes (“Notes”). This amortization was excluded from management’s assessment of the Company’s core operating performance. Although the amortization of debt discount is recurring in nature, the expected life of the Notes is five years as that is the earliest date in which the Notes can be put back to the Company at par value. The amortization period ended October 1, 2011, therefore the Company no longer records an amortization of debt discount. In addition, over the past several years, the Company has repurchased some of its Notes, which made the principal amount outstanding and related amortization vary from period to period, and as such the Company believes the exclusion of the amortization facilitates comparisons with the results of other periods that may reflect different principal amounts outstanding and related amortization.

Gain on sale of assets – The Company excluded the gain recorded for the sale assets. During the second quarter of 2010, the Company sold assets located in Germany and this gain was excluded from management’s assessment of the Company’s core operating performance. The Company believes the exclusion of the gain on sale of assets provides investors an enhanced view of a gain the Company may incur from time to time and facilitates comparisons with results of other periods that may not reflect such gains.

Impairment of long-lived assets – The Company excluded the impairment of long-lived assets. During the third quarter of 2010, the Company impaired certain assets, which was excluded from management’s assessment of the Company’s core operating performance. The Company believes the exclusion of the impairment of long-lived assets provides investors an enhanced view of a loss the Company may incur from time to time and facilitates comparisons with results of other periods that may not reflect such impairments.

Forgiveness of debt – The Company excluded the forgiveness of debt related to one of its Asia subsidiaries. The forgiveness of debt is excluded from management’s assessment of our operating performance. The Company believes the exclusion of the forgiveness of debt provides investors an enhanced view of the adjustment the Company may incur from time to time and facilitates comparisons with the results of other periods that may not reflect such charges.

ADJUSTED EARNINGS PER SHARE (Non-GAAP)

This non-GAAP financial measure is the portion of the Company’s GAAP net income assigned to each share of stock, excluding amortization of acquisition related intangible assets, amortization of debt discount, gain on sale of assets, impairment of long-lived assets, and forgiveness of debt as described above. Excluding gain on sale of assets, impairment of long-lived assets, and forgiveness of debt 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 amortization of debt discount allows for comparison of the Company’s 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. The Company recommends a review of diluted earnings per share on both a GAAP basis and non-GAAP basis be performed to obtain a comprehensive view of the Company’s results. Information on how these share calculations are made is included in the reconciliation table provided.

CASH FLOW ITEMS

Free cash flow (FCF) (Non-GAAP)

FCF for fiscal 2011 and fourth quarter of 2011 is a non-GAAP financial measure, which is calculated by taking cash flow from operations less capital expenditures. For fiscal 2011 the amount was ($19.3) million ($61.6 million less (-) $80.9 million) and for fourth quarter 2011, the amount was ($14.5) million (($3.4) million less (-) ($11.1) million). FCF represents the cash and cash equivalents that we are able to generate after taking into account cash outlays required to maintain or expand property, plant and equipment. FCF is important because it allows us to pursue opportunities to develop new products, make acquisitions and reduce debt. In addition, FCF was impacted by certain tax items included in cash flows from operations, see the next item for further details.

Adjusted cash flows from operations (Non-GAAP)

For fiscal 2011 and fourth quarter 2011, in accordance with U.S. GAAP, certain tax items relating to our retirement of Notes have been recorded in cash flows from operations. Adjusted cash flows from operations is a non-GAAP financial measure, which is calculated by taking cash flows from operations and adding back certain tax items relating to our retirement of Notes. For fiscal 2011 the amount was $77 million ($62 million plus (+) $15 million) and for fourth quarter 2011, the amount was $12 million (($3) million plus (+) $15 million). Although other items related to retirement of the Notes were included in cash flows from financing, U.S. GAAP does not allow certain tax related items to be included in cash flow from financing. This non-GAAP exclusion is important because it identifies certain tax items that would not have been included in cash flows from operations had we not had the retirement of Notes.

Adjusted FCF (Non-GAAP)

Adjusted FCF is a non-GAAP financial measure, which is calculated by taking FCF and adding back certain tax items in cash flows from operations related to our retirement of Notes as described above. For fiscal 2011 the amount was ($4) million (($19) million plus (+) $15 million) and for fourth quarter 2011, the amount was $0.5 million (($14.5) million plus (+) $15 million).

DIODES INCORPORATED AND SUBSIDIARIES

CONSOLIDATED RECONCILIATION OF NET INCOME TO EBITDA

EBITDA represents earnings before net interest expense, income tax provision, depreciation and amortization. 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, 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 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 used by other companies. Furthermore, EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not consider certain cash requirements such as tax and debt service payments.
