Dr. Keh-Shew Lu, President and CEO of Diodes

Thank you, Leanne. Welcome everyone, and thank you for joining us today.

We are very excited about today’s announcement regarding the proposed acquisition of BCD Semiconductor by Diodes. I believe this transaction offers substantial synergies and a compelling strategic rationale for both companies’ customers, employees, and shareholders. As we will discuss today, this transaction meets all of our acquisition criteria and will also be immediately accretive to GAAP earnings per share.

As Leanne mentioned, there is a slide presentation available on our website, which I will now review with you as part of today’s call before we open the call for your questions.

Slide 3: A Winning Combination

Diodes’ acquisition of BCD Semiconductor creates a stronger global company with greatly enhanced analog offerings. When looking at the strengths and expertise of each company, Diodes has:

BCD Semiconductor has:

When combined, there are many synergies including:

Slide 4: Transaction Overview

At the effective date of the merger, each American Depository Share, which represents six ordinary shares of BCD, will be converted into the right to receive $8.00 in cash, without interest. The aggregate consideration will be approximately $151 million dollars. The acquisition is expected to close late in the first quarter or early in the second quarter of 2013. The boards of both companies have approved the transaction, which is still subject to approval by BCD’s shareholders, as well as other customary closing conditions and regulatory approvals.

Slide 5: BCD Highlights

Let me now provide an overview of BCD’s business from both a corporate and financial perspective. As a leading supplier of standard linear and power management, BCD has a solid product portfolio that includes AC/DC solutions for chargers and adapters. The company was founded in 2000, IPO’ed in February of 2011 on Nasdaq, and is incorporated in the Cayman Islands. The company has over 1300 employees and 300 products with sales

Page 5 of 10

offices in Shanghai, Shenzhen, Taipei, Seoul and the U.S. BCD also has in-house design and wafer capabilities in Shanghai with a second fab near completion also in Shanghai. A large majority of the company’s product packaging is outsourced to partners in Taiwan and China.

In terms of financials, BCD reported revenue for the first nine months of 2012 of $106 million with $14 million in EBITDA and a cash balance of approximately $39 million as of September 30, 2012.

Slide 6: Transaction Rationale

These business strengths and attributes strongly support our rationale for the transaction and will greatly benefit Diodes’ business and expand our product offerings. The rationale for the transaction includes:

Page 6 of 10

Slide 7: Broad Consolidated Product Offerings

From a product perspective, the combined company offers a significant increase in the depth and breadth of product offerings. The white represents Diodes products, the pink highlighted section are BCD’s products, and the light blue sections represent the synergistic product portfolio. Together, the combined portfolios are complementary and enhance the product offerings available to support a larger, more diverse customer base. As a result, we expect to realize significant cross-selling opportunities, which will increase the combined company’s sales across the expanded customer base.

Slide 8: Global Manufacturing Infrastructure

In terms of manufacturing, our global infrastructure will consist of Diodes’ wafer fabs in Kansas City and Oldham, UK; and our packaging facilities in Shanghai, China, Neuhaus, Germany as well as our joint venture packaging facility in Chengdu, China. BCD will add an additional wafer fab in Shanghai and is also in the process of completing a second fab near Shanghai.

Slide 9: Financial Overview Post Acquisition

This transaction provides Diodes with a large revenue base as well as the ability to achieve manufacturing and operational synergies in order to expand our markets and accelerate margin growth. When looking at the combined 2012 pro-forma results, revenue would be approximately $776 million with a healthy gross profit of approximately $198 million and gross margin of approximately 25.6 percent. For the first nine months of 2012, the combined entities generated significant cash flow and EBITDA of $83 million. As a result, the transaction will be immediately accretive to GAAP earnings per share. Additionally, we believe there is opportunity for further expansion and margin growth — through manufacturing and packaging synergies as well as capacity efficiencies.

On slides 12 and 13 we have provided the definition of EBITDA as well as a reconciliation of net income to EBITDA of both companies as well as the combined entity for the nine months ended September 30, 2012.

Slide 10: How BCD Fits into Diodes M&A Strategy

In summary, we believe that BCD Semiconductor is a strong strategic fit and meets the acquisition criteria that we have been consistently communicating to our shareholders and investors:

Slide 11: Diodes Strategy: Profitable Growth

To conclude, Diodes’ focus continues to be on producing profitable growth through a combination of manufacturing cost leadership, high volume end market focus, strong customer relationships, aggressive new product introductions, product portfolio expansion, innovative process and packaging technology as well as select strategic acquisitions. BCD is another key milestone in this growth strategy, and I look forward to reporting on the company’s combined success in 2013.

With that, we will now open the call for questions.

(Non-GAAP) 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. For example, our EBITDA takes into account all net interest expense, income tax provision, depreciation and amortization without taking into account any attributable to noncontrolling interest. 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.
