Item 7. Financial Statements, Proforma Financial Information and Exhibits. (c) EXHIBITS Exhibit 99.1 - Press Release dated April 29, 2003 Item 9. Regulation FD Disclosure This information furnished under "Item 9. Regulation FD Disclosure" is intended to be furnished under "Item 12. Results of Operations and Financial Condition" in accordance with SEC Release No. 34-47583. On April 29, 2003, Diodes Incorporated issued a press release announcing first quarter 2003 earnings. A copy of the press release is attached as Exhibit 99.1. On April 29, 2003, Diodes Incorporated held an investor teleconference in reference to first quarter 2003 earnings. During the teleconference, the Company made the following statements: "Gross margin at 24.6% was off 70 basis points from 25.3% in the fourth quarter, but was a significant improvement from 16.2% in the first quarter of 2002. The year-over-year improvement is largely due to increased capacity utilization in both our China and North America manufacturing facilities and improvements in our operating efficiencies. For the quarter, our manufacturing facility in China ran at above 90% capacity, up from 58% in the first quarter of 2002 and 84% in the fourth quarter. Our wafer fab ran at an average of over 80%, up from 65% last year and 77% in the fourth quarter." "While net income was modestly below the fourth quarter, as outlined in our last conference call, in the fourth quarter we had the benefit of the reversal of some accrued compensation as well as the receipt of two quarters of high technology grants from China of approximately $244,000. As projected, we did not receive any grants in the first quarter but we do anticipate receiving a grant in the second quarter." "Capital expenditures were approximately $3.9 million in the first quarter and we maintain our full year capital expenditure estimate of $12 to $14 million as we approach higher capacity utilizations and bring new products into production." "Our book-to-bill is presently over 1.0 and relatively consistent with the fourth quarter." "Depreciation for the quarter was approximately $2.6 million." The information in this Form 8-K and the Exhibits attached hereto shall not be deemed "filed" for purposes of Section 18 of the Securities Act of 1934, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference in such filing. 2

Exhibit 99.1 Diodes Incorporated FOR IMMEDIATE RELEASE Diodes Incorporated Reports First Quarter 2003 Results o Revenue increases 9.4% to $29.5 million due to growing penetration in Asian markets Westlake Village, California, April 29, 2003 - Diodes Incorporated (Nasdaq: DIOD), a leading manufacturer and supplier of high quality discrete semiconductors, today reported financial results for the first quarter of fiscal year 2003 ended March 31, 2003. First Quarter Highlights: Revenue increases 9.4% from 1Q02 to $29.5 million in 1Q03 Net income increased to $1.9 million, or $0.21 per diluted share, up from $208,000, or $0.02 per diluted share, in the same period last year Sales from Asia represent 56% of revenue, reflecting growing regional market share New product revenue accounts for a record 11% of sales Develops breakthrough Schottky barrier process for high efficiency applications Revenues for the first quarter of 2003 were $29.5 million, a sequential increase of 2.7% from the fourth quarter of 2002, and an increase of 9.4% from the first quarter of 2002. Net income for the quarter was $1.9 million, as compared to $208,000 for the three months ended March 31, 2002 and compared to $2.3 million in the fourth quarter ended December 31, 2002. Diluted earnings per share were $0.21 for the first quarter of 2003, as compared to $0.02 for the same period last year. Commenting on the quarter, C.H. Chen, President and CEO of Diodes Incorporated, said, "We are encouraged by our results in the first quarter. Despite an unprecedented combination of challenging factors, including the inconsistent recovery pattern of the semiconductor industry, seasonal weakness, and geopolitical issues, Diodes maintained our focus on increasing revenue, growing market share and continuing our excellence in manufacturing and customer service. After nearly two years of significant expansion of sales and marketing in the Asia region, we are beginning to realize the benefits of this strategy." Diodes growth in the first quarter was driven by the Asian market, which accounted for 56% of sales, up from 47% in the same period last year. Demand for the Company's new products for compact energy-efficient devices, including Powermite(R)3 and Performance Schottky, and the Company's ability to provide better service and support to a growing Asian customer base, enabled Diodes to capture a greater share of this market. "For the first quarter, our gross profit margin was 24.6%, as compared to 16.2% in the first quarter of 2002 and 25.3% in the prior quarter. Gross margin was impacted by fluctuations in our product mix and competitive pricing on our commodity devices and wafers. However, we expect to see gradual margin expansion going forward, as new products continue to increase as a percentage of sales," stated Mr. Chen. For the quarter, SG&A expenses were $4.1 million as compared to $3.9 million in the fourth quarter of 2002 and $3.8M in the first quarter of 2002. The increase is primarily due to increased insurance costs, selling expenses and incentives, but SG&A expenses as a percentage of sales remained relatively flat at 14.1%. "Diodes continues to invest in research and development efforts to develop new technology and increase our product range towards higher margin, differentiated products. We expect that our R&D expenditures will increase and that most of these dollars will be spent at our product development facility at Diodes-FabTech," said Mr. Chen. 4

"Last year, we began the collaborative development and manufacturing effort between Diodes-FabTech and Diodes-China with the launch of the UDZ series. During the quarter, we announced the development of a breakthrough ultra-low leakage, high voltage Schottky barrier rectifier process. This breakthrough technology, which was developed at Diodes- FabTech, will lead to new products for high efficiency switch-mode power supply (SMPS) applications, such as adaptors, desktops and automotive uses, and allows our customers to boost their power supplies' overall efficiency and gain a competitive edge. We expect to introduce several new higher margin products using this technology over the next two quarters, including a new line of Powermite(R)3 products manufactured at our Diodes-China facility." At March 31, 2003, Diodes had $8.5 million in cash and cash equivalents, $16.9 million in long-term debt, $6.5 million outstanding on its revolving credit line and $59.9 million in shareholders' equity. Mr. Chen concluded, "In light of the current economic climate, we remain cautious about predicting the timing of any improvement in the computer and communications markets. Therefore, for the second quarter, we are projecting revenue to be flat to slightly up on a sequential basis. However, as capital spending and PC demand improves and as we continue to introduce new higher margin, proprietary products, we expect the second half of the year to be stronger and to realize the operating leverage in our business."
