Detailed Report for Investors

On March 5, 2026, the Audit Committee of Diodes Incorporated’s Board of Directors took decisive action by dismissing Baker Tilly US, LLP (“Baker Tilly”) as the company’s independent registered public accounting firm. This move is effective immediately and marks a significant shift in the company’s auditing relationship.

Background and Rationale:

As per the company’s filing, there have been no adverse opinions, disclaimers of opinion, or modifications of any kind in the audit reports issued by Baker Tilly on Diodes’ consolidated financial statements. The reports for the fiscal years ended December 31, 2025 and 2024 were unqualified, and no issues related to uncertainty, audit scope, or accounting principles were raised.

Importantly, there have been:

• No disagreements between Diodes and Baker Tilly on matters of accounting principles, financial statement disclosure, or auditing procedures that would have been referenced in Baker Tilly’s reports.
• No reportable events as defined in Item 304(a)(1)(v) of Regulation S-K during the relevant period.

In line with regulatory requirements, Diodes provided Baker Tilly with a copy of its disclosures and requested that Baker Tilly furnish the SEC with a letter stating whether it agreed with the statements made. Baker Tilly concurred and their letter, dated March 11, 2026, has been filed as Exhibit 16.1 to the company’s Form 8-K filing.

Engagement of PricewaterhouseCoopers LLP (PwC):

Following pipeline best practices, the Audit Committee has approved PricewaterhouseCoopers LLP (“PwC”) as the company’s new independent registered public accounting firm for the year ending December 31, 2026. Notably, during the two most recent fiscal years and the interim period up to March 5, 2026, neither Diodes nor anyone acting on its behalf consulted with PwC concerning:

• The application of accounting principles to specific completed or proposed transactions,
• The type of audit opinion that might be rendered on the financial statements, or
• Any matter that was the subject of disagreement or reportable event with the previous auditor.

Shareholder Impact and Price Sensitivity Analysis

Why is this important for shareholders?

• Auditor Changes Are Material Events: A change in independent auditor can be interpreted by the market as a sign of changes in corporate governance, financial controls, or future strategic direction. Although Diodes has stated there were no disagreements or reportable events, investors often scrutinize such announcements for underlying issues or signals about future financial reporting.
• Appointment of PwC: PwC is one of the “Big Four” accounting soprs and its engagement could be seen as a move to enhance financial reporting rigor, improve transparency, or prepare for increased scrutiny and growth. This could be a positive signal for institutional investors and may enhance investor confidence.
• No Red Flags in Transition: The absence of disagreements or reportable events reduces the risk of negative surprises related to financial reporting or undisclosed issues, which should provide some reassurance to shareholders.

While this news is not, in itself, a sign of operational or financial distress, the change to a major global auditor could be interpreted as a step up in governance or a prelude to strategic initiatives. Investors should monitor Diodes’ subsequent filings and communications for any changes in financial policies, strategies, or disclosures.
