Revenues for the first quarter of 2006 were $73.6 million, an increase of 51.4% from the first quarter of 2005, and a sequential increase of 19.9% from the fourth quarter of 2005. Net income for the quarter increased 28.6% to $9.3 million, compared to $7.2 million for the three months ended March 31, 2005. Diluted earnings per share were $0.34 for the first quarter of 2006, as compared to $0.31 for the same period last year reflecting additional shares from the follow-on offering. First quarter 2006 net income includes $1.4 million related to stock option expensing. Under FAS 123(R), the Company began expensing stock options in the first quarter of 2006, and therefore, equivalent share-based compensation expense was not reflected in prior periods.

Commenting on the quarter, Dr. Keh-Shew Lu, President and CEO of Diodes Incorporated, said, “We are very pleased to report another quarter of record revenues and strong profitability, reflecting the success of our growth strategy and excellent reception to our new products by Diodes’ global customers. During the first quarter, we were able to enter the analog market successfully, with the completion of the Anachip acquisition and the introduction of our first series of new standard linear devices targeting high-volume applications.

“We have made excellent progress in integrating Anachip with Diodes’ product offerings and that of our sales and marketing organization. Over the balance of 2006, we intend to complete the manufacturing integration of analog products with our world-class packaging capability in China, which we expect will have a favorable impact on our gross margins. Customer interest in our expanded product offerings has been very strong, and we believe that we are well positioned for substantial future growth in both the discrete and analog segments.”

Mark King, Senior Vice President of Sales and Marketing, stated, “Our very strong growth in Asia was driven primarily by the Anachip acquisition, with robust demand for applications in LCD monitors, TVs, Wireless LANs, and battery chargers more than compensating for some seasonal weakness in motherboard and digital audio players. As a result of the Anachip acquisition, we have significantly increased our sales and applications team in China, realized synergies with our Taiwan sales team, and gained a new Korean sales office that strengthens our footprint in this key market.”

“North America sales exceeded our expectations, with brisk demand for TV set-top boxes and hand-held medical devices. Sales to customers that design in the United States and build in Asia remained strong, with intensified new design activity as well as new qualifications to ‘second source’ long lead-time parts. We have seen strong design activity for our growing family of array products, as customized arrays gain traction with applications requiring very small form factors. There is also robust interest in our new PowerDI123 packages, resulting in several new design wins,” said Mr. King.

“Revenue in Europe rose better than 50% sequentially, reflecting strong demand by both OEM accounts and distributors. We are very pleased with the performance of our recently expanded distribution network in Europe, adding additional sales staff in France and Germany, and had our most successful quarter ever for design wins with European accounts,” concluded Mr. King.

New product revenues reached a record 23% during the quarter, reflecting the large number of recently introduced products from the Anachip acquisition. At the end of the first quarter, Diodes launched a new Synchronous Pulse Width Modulation (PWM) Controller in a series of planned analog integrated circuit (IC) part introductions into Diodes’ analog power management product line.

“We are very pleased with customer reception to our new standard analog power management products, and we have a very aggressive product development road map in place targeting analog applications where we see the opportunity to leverage our highly efficient packaging capabilities,” stated Dr. Lu. “Along with the new controller, we released six industry standard analog products and two surface-mount package types now manufactured at our China facility. These new packages enable us to compete in the high-volume analog IC market and expand our discrete offerings in the medium-power range.”

Gross profit for the first quarter of 2006 was $24.2 million, compared to $21.4 million in the fourth quarter of 2005, and a 45.9% increase over $16.6 million in the first quarter of 2005. Gross margin for the quarter was 32.9%, compared to 34.1% of sales for the same period in 2005, reflecting the lower gross margins associated with the current analog products. The Company expects that gross margins will benefit from the planned manufacturing integration of analog products in the second half of 2006. Excluding share-based expenses included in cost of goods sold, first quarter gross margin would have been 33.1%.

For the quarter, SG&A expenses were $11.3 million, or 15.3% of sales, as compared to $6.7 million, or 13.8% of revenue, in the comparable quarter last year. Included in SG&A expenses were $1.3 million in non-cash, share-based compensation. For comparable purposes, excluding the share-based compensation, SG&A for the first quarter of 2006 would have been 13.5% of sales. (See table for a reconciliation of the impact of share-based compensation expense to reported results.)

Investment in research and development rose by $1.1 million to $2.0 million, or 2.7% of revenue, compared to 1.9% of revenue in the first quarter of 2005. The increase in R&D reflects the impact of the Anachip acquisition and Diodes’ investment in developing new products in the discrete, analog and mixed signal segments.

At March 31, 2006, Diodes had $99.5 million in cash and short-term investments, $139.2 million in working capital, and $6.6 million in long-term debt. For the first quarter, the Company generated cash flow from operations of $17.0 million, and shareholders’ equity increased 6.6% to $240.4 million.

“Entering the second quarter, shipments and orders for delivery continue to show strength with a book-to-bill ratio above one. Given our strong momentum in the marketplace and expanded addressable markets, we expect that revenues will increase sequentially by an additional 3-6% in the second quarter. We expect second quarter gross margin percentage to be comparable to the first quarter and we expect to see gradual expansion in our gross margin over the balance of 2006 and beyond, as we continue to execute our strategy,” Dr. Lu concluded.

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 in evaluating companies in our industry. In addition, our management believes that EBITDA is useful 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 and income taxes and the accounting effects of capital spending, which items may vary for different companies for reasons unrelated to overall operating performance. As a result, our management uses EBITDA as a measure to evaluate the performance of our business. However, 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.
