Corporate Conduct and Ethics Implementation

TSMC’s Board of Directors strives to perform the responsibilities of supervising the corporate conduct and ethics compliance practice through the Audit and Risk Committee and the Compensation and People Development Committee, the hiring of a financial expert consultant for the Audit and Risk Committee, and coordination with the Internal Audit department. The General Counsel and the Corporate & Compliance Legal Division (which directly reports to the General Counsel) promotes the Company’s ethical standards, and the General Counsel reports quarterly to the Board on the implementation status. In addition, both the responsible senior manager appointed by the CEO to oversee the Ombudsmen system and Internal Auditors update the Board on ethical standards and compliance issues on a regular basis. Moreover, TSMC’s officers, especially our CEO, CFO, and General Counsel, with oversight from our Board, are responsible for the full, fair, accurate, timely, and understandable financial accounting and financial disclosure in reports and documents filed by the Company with securities authorities and in all TSMC public communications and disclosures.

Furthermore, to ensure that our conduct meets relevant legal requirements and the highest ethical standards under the Ethics Code, TSMC provides multiple channels for reporting business conduct concerns. Please refer to Assessment Item 3 for details. We do not tolerate any violation of the Ethics Code and treat every possible violation incident seriously. Each violator of the Ethics Code (or relevant regulations), for employees, in addition to affecting individual annual performance evaluation, will be severely disciplined to the full extent of our policies and the law, up to and including immediate dismissal, or termination of business relationship for suppliers, and judicial prosecution as appropriate.

In 2025, there were 77,293 attendances that completed the “Annual Ethics and Compliance Training Course” (mandatory 0.5 hour online course) at TSMC and its subsidiaries, with the exam pass rate reaching 100%.

In 2025, TSMC did not receive any reports related to finance, accounting or antitrust matters, nor did we receive any complaints concerning breach of customer privacy and loss of customer data, or any material regulatory violations (where a fine exceeds NT$1 million), including non-monetary sanctions.

In 2025, the incidents reported through the Audit Committee Whistleblower System, Ombudsman System, and Irregular Business Conduct Reporting System totaled 358.

One incident were verified upon investigation and determined for disciplinary action by the Ethics Committee. In 2025, TSMC leveraged the four violations to strengthen ethics promotion for all employees in supplier-related activities.
