**Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.** 

*Director Resignation* 

On May 11, 2026, at the 2026 Annual Meeting of Stockholders of Diodes Incorporated (the "Company"), Dr. Keh-Shew Lu, a nominee for re-election to the Company's Board of Directors (the "Board"), received a greater number of votes "withheld" from his election than votes "for" his election. Pursuant to the Company's Director Resignation Policy, any director nominee in an uncontested election who receives a greater number of votes "withheld" than votes "for" is required to tender his or her resignation to the Board for its consideration, following review and recommendation by the Governance and Stockholder Relations Committee of the (the "Governance Committee") Board in accordance with the policy.

Following certification of the voting results from the 2026 Annual Meeting of Stockholders, and in light of the voting outcome described above, Dr. Lu informed the Company that, rather than tendering a resignation for consideration under the Director Resignation Policy, he was voluntarily resigning from the Board of Directors effective immediately. Dr. Lu indicated that, after considering the voting results and the circumstances surrounding his re-election, he believed it was appropriate to step down from the Board immediately rather than remain in office pending the review process contemplated by the Director Resignation Policy.

Dr. Lu's resignation was voluntary and was not the result of any disagreement with the Company on any matter relating to the Company's operations, policies or practices.

As a result of Dr. Lu's voluntary resignation, it was not necessary for the Governance Committee and the Board to conduct the review and recommendation procedures contemplated by the Director Resignation Policy.

Dr. Lu will remain an employee of the Company, serving as Special Advisor to the Chief Executive Officer.

*Appointment of Chairperson*

Following Dr. Lu's resignation, on May 11, 2026, the Board appointed Ms. Angie Chen Button as Chairwoman of the Board.

**Item 5.07 Submission of Matters to a Vote of Security Holders.**

*Results of the Annual Meeting*

The Company submitted the following matters to a vote of its security holders at the Company's 2026 annual meeting of stockholders on May 11, 2026, each of which is described in more detail in the Company's proxy statement filed with the Securities and Exchange Commission on April 1, 2026: (1) the election of seven persons to the Board of Directors of the Company, each to serve until the next annual meeting of stockholders and until their respective successors have been elected and qualified; (2) the approval, on an advisory basis, of the Company's executive compensation; and (3) the ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026.

**Diodes Incorporated Announces Retirement of Chairman Dr. Keh-Shew Lu and Election of Angie Chen Button as Chairwoman of the Board**

**Plano, Texas – May 12, 2026** -- Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announced that Dr. Keh-Shew Lu has retired as Chairman of the Board of Directors, effective immediately, following more than 25 years of distinguished service to the Company. The Board of Directors has elected Ms. Angie Chen Button to serve as Chairwoman of the Board.

**Retirement of Dr. Keh-Shew Lu**

Dr. Lu joined Diodes in June 2005, when the Company had annual revenue of approximately $215 million. Over the course of his tenure, Dr. Lu played a central role in scaling the business by more than 500%, establishing Diodes as a leading, multibillion-dollar semiconductor company. Under his leadership, the Company successfully completed ten strategic acquisitions, navigated multiple industry cycles, including a global pandemic, and maintained a record of consistent profitability now spanning 34 consecutive years.

"Dr. Lu's contributions to Diodes over the past two decades have shaped this Company in lasting ways," stated Gary Yu, CEO and President of Diodes Incorporated. "On behalf of the entire Board and our global workforce, we extend our deepest gratitude to Dr. Lu for his exceptional service and leadership."

**Election of Angie Chen Button as Chairwoman**

Following Dr. Lu's retirement, the Board has elected Ms. Angie Chen Button as Chairwoman of the Board. Ms. Button joined the Diodes Board in April 2021 as an independent director and has served as Lead Director since May 2023, during which time she has helped strengthen independent Board oversight, facilitated effective communication between independent directors and management, and advanced the Board's focus on strategic priorities and long-term value creation. She previously served as Chair of both the Governance and Stockholder Relations Committee and the Compensation Committee.

Ms. Button brings a unique combination of industry, financial, and public-sector experience to the role. She has served in the Texas House of Representatives since 2009 and currently chairs the Trade, Workforce, and Economic Development Committee. Her legislative career has included leadership of multiple key committees as well as service on budget and taxation committees. She has been recognized as a "Top 10 Best Legislator" by Texas Monthly in both 2021 and 2023 and has received several distinguished leadership awards.

Earlier in her career, Ms. Button spent over 30 years at Texas Instruments in roles spanning audit, finance, procurement, business development, and international marketing. She has also brought valuable governance experience through her service on the Audit Committee of the Dallas Area Rapid Transit Board.

"It is a privilege to assume the role of Chairwoman of Diodes," said Ms. Button. "I am committed to building on the Company's strong track record of execution by working collaboratively with the Board and leadership team to support continued growth, innovation and long-term value creation."

Mr. Yu further commented, "I've had the privilege of working closely with Angie and have seen firsthand her thoughtful leadership and strong commitment to the Company. Her deep semiconductor industry background, combined with her extensive legislative and governance experience, makes her exceptionally well positioned to lead our Board as we continue to execute our strategy and drive continued revenue and earnings growth."
