Diodes Incorporated Appoints Evan Yu to Board of Directors as Independent Member

New Director Brings Three Decades of Semiconductor Industry Experience

Evan Yu's appointment to Diodes Incorporated's Board of Directors represents a significant addition of seasoned semiconductor leadership. The disclosure identifies Yu as possessing deep expertise across power products, wireless communications, application-specific integrated circuits (ASIC), and digital signal processing (DSP) technologies. His professional background encompasses strategic operating leadership, international market insight, and corporate governance perspective developed through decades of managing multi-regional technology businesses, expanding product portfolios, and driving growth across diversified semiconductor markets.

Yu's return to the company board follows his retirement from an executive position at Diodes in January 2023. During his tenure at the company, which began in 2008, he held the title of Senior Vice President, Worldwide Power Products, where he led global strategy and operating execution for the worldwide power products business. His responsibilities included oversight of cross-functional teams spanning product development, engineering, marketing, and commercial operations across key international markets. The filing indicates he also drove portfolio expansion and business performance across diversified semiconductor applications while serving as Asia President and holding director and senior leadership roles across subsidiaries and affiliated entities.

Texas Instruments Background and Leadership Credentials

Before joining Diodes Incorporated, Yu accumulated 15 years of experience at Texas Instruments, one of the semiconductor industry's largest global companies. During his tenure there, he held several key management roles, including Asia Vice President of the Application Specific Products (ASP) organization. In the ASP division, Yu's responsibilities included leading business development, marketing, and technical units covering wireless communications, ASIC, DSP, broadband, and digital still camera business units. This background demonstrates extensive exposure to multiple technology domains and cross-functional business operations at a Fortune 500 semiconductor manufacturer.

Between his Texas Instruments career and joining Diodes, Yu served as Chief Executive Officer of Commit Inc., an Asian-based wireless communications chipset company focused on third-generation and fourth-generation (3G/4G) cellular technologies. This CEO experience provided him with operational responsibility for an independent semiconductor enterprise focused on mobile communications infrastructure. Most recently, prior to his board appointment, Yu served as Chairman of the Board of Canyon Semiconductor Inc., demonstrating continued engagement with semiconductor industry governance and strategy.

Education and International Business Perspective

Yu's educational credentials include formal training in electrical engineering from institutions based in Taiwan. The filing discloses that he studied electrical engineering at Kaohsiung Institute of Technology and earned his bachelor's degree in Electrical Engineering from Tam Kang University in Taiwan. This international educational background, combined with his extensive career experience across Asian markets and multinational semiconductor organizations, positions him to provide cross-border market insight and governance perspective to the board.

The combination of Taiwan-based electrical engineering education and three decades of professional experience spanning Asia, Texas Instruments, and semiconductor startups aligns Yu's background with the global nature of semiconductor manufacturing and distribution. His career progression from technical engineering education through operational roles in Asia at Texas Instruments, CEO responsibilities at a wireless chipset company, and senior executive positions at Diodes suggests familiarity with the strategic and technical challenges facing semiconductor companies operating across multiple geographic and product markets.

Independence Certification and Governance Compliance

The disclosure confirms that Yu qualifies as an independent director under Nasdaq's corporate governance standards and the independence requirements established by Rule 10A-3 under the Securities Exchange Act of 1934, as amended. This certification indicates that the board's governance process determined that no material relationships exist that would compromise Yu's ability to exercise independent judgment on matters before the board. The filing explicitly states that Yu was not appointed to the Board pursuant to any arrangement or understanding with any other person, establishing that his selection followed standard director nomination procedures.

Additionally, the announcement discloses that Yu has no family relationships with any director or executive officer of the company and there are no transactions in which Yu has an interest requiring disclosure under Item 404(a) of Regulation S-K. These confirmations address potential conflict-of-interest concerns that typically arise when former executives return to corporate boards. The independent director status and absence of material relationships or family ties provide assurance that Yu's board participation will not be constrained by undisclosed conflicts or informal arrangements that could influence his voting or decision-making on matters of corporate governance.

Return of Company Insider Strengthens Board Continuity

Yu's appointment represents a return of an executive with direct knowledge of Diodes Incorporated's operations, strategy, and competitive position. Having served as Senior Vice President of Worldwide Power Products from 2008 through his January 2023 retirement, Yu developed familiarity with the company's organizational structure, product portfolio, market positioning, and business culture. This institutional knowledge may enable him to contribute more effectively to board discussions regarding strategic initiatives, competitive positioning, and operational challenges compared to an entirely external director candidate.

The decision to appoint a former senior executive who had previously led a major business unit suggests the board valued continuity of strategic perspective combined with Yu's external CEO and industry governance experience gained since his retirement. His interim experience at Canyon Semiconductor and other roles outside the company demonstrate that he has maintained engagement with semiconductor industry trends and governance practices since leaving Diodes. This combination of internal knowledge and external perspective may position Yu to bridge institutional memory with evolving market dynamics and governance best practices.

Power Products Business Leadership and Strategic Portfolio Expansion

During his years as Senior Vice President of Worldwide Power Products at Diodes, Yu led the company's strategic positioning in power semiconductor technologies, a critical segment of the broader semiconductor industry. The filing describes his role as involving global strategy and operating execution for this business unit, along with oversight of cross-functional teams in product development, engineering, marketing, and commercial operations. His success in driving portfolio expansion and business performance across diversified semiconductor applications suggests capability in navigating complex product-market dynamics and managing growth initiatives.

Power products represent a significant portion of many semiconductor companies' revenue, spanning applications from power management in consumer electronics to industrial and automotive power conversion systems. Yu's three-decade career spanning Texas Instruments' diverse product portfolio, a wireless chipset CEO role, and leadership of Diodes' worldwide power products business indicates exposure to multiple end markets and technical applications. This breadth of experience across power products, wireless communications, and ASIC technologies positions him to provide informed perspective on product strategy, competitive positioning, and market opportunities in multiple semiconductor segments.

Asia-Pacific Market Expertise and Regional Growth Opportunities

The disclosure highlights Yu's role as Asia President during his tenure at Diodes Incorporated, indicating significant responsibility for the company's operations and strategy in the Asia-Pacific region. Combined with his earlier experience as Asia Vice President at Texas Instruments and his CEO role at an Asian-based wireless communications company, Yu brings substantial expertise in one of the world's largest semiconductor markets. His regional leadership experience spans multiple decades and multiple companies, suggesting deep familiarity with manufacturing ecosystems, distribution channels, customer relationships, and competitive dynamics across Asian markets.

The Asia-Pacific region represents a critical growth market for semiconductor companies, encompassing major manufacturing hubs, technology innovation centers, and consumption markets. Yu's background in expanding product portfolios and driving growth in technology markets within this region may enable the board to benefit from informed perspective on international expansion opportunities, regional market trends, and strategies for competing in Asia-Pacific across multiple product segments. His director and senior leadership roles across subsidiaries and affiliated entities in the region suggest hands-on experience with operating across different regulatory environments and business structures in Asia.

Timing of Appointment and Board Composition Implications

The filing indicates that the Board of Directors elected Yu on July 27, 2026, with his appointment becoming effective on August 1, 2026. The company announced the election through a press release issued on July 28, 2026. This timing represents a structured onboarding process allowing four business days between the formal election and the effective date of board service. The disclosure does not indicate whether this appointment fills a newly created board position, replaces a departing director, or expands the overall size of the board.

The appointment of Yu, with his deep operational experience in power products and other semiconductor technologies, suggests the board may be prioritizing technical and operational expertise alongside his governance and strategic perspective. The combination of his previous role as Senior Vice President at Diodes with his subsequent CEO and board chairman experience outside the company indicates a deliberate effort to secure an individual capable of contributing both institutional knowledge and external market insight to board deliberations on strategy, competitive positioning, and corporate governance matters.

Regulation FD Disclosure and Public Announcement Process
