Diodes Incorporated Updates Fourth Quarter 2010 Guidance

     Dallas, Texas — December 9, 2010 — 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 updated its guidance for the fourth quarter of 2010.

The Company is maintaining its revenue and gross margin guidance for the fourth quarter of 2010 as it anticipates revenue to range between $160 million and $168 million, or between a decrease of 2 percent and an increase of 3 percent sequentially, and gross margin is expected to be comparable to the third quarter of 2010 level of 37.4 percent. In addition, the Company is revising its guidance for operating expenses and tax rate. The Company now expects operating expenses as a percent of revenue to decrease 50 to 100 basis points from third quarter 2010 level versus its previous guidance of comparable to third quarter 2010. Also, the Company now projects its fourth quarter tax rate to be approximately 20 to 24 percent due to an operating expense improvement in higher tax rate jurisdictions versus its previous guidance of 17 to 23 percent. Shares used to calculate GAAP EPS for the fourth quarter are anticipated to be approximately 46.3 million, the same as the prior guidance.
