Material Changes and Legal Action
The primary material event is the filing of a lawsuit on November 25, 2025, in the Intellectual Property and Commercial Court against Wei-Jen Lo, TSMC's former Senior Vice President. Key details include:
- Defendant Background: Lo joined TSMC in 2004, became Senior Vice President in 2014, and retired on July 27, 2025.
- Alleged Misconduct: After transferring to Corporate Strategy Development in March 2024, Lo allegedly convened meetings with R&D staff to gather information on advanced technologies despite no longer supervising R&D.
- Non-Compete Violation: During his exit interview on July 22, 2025, Lo stated he would join an academic institution. He subsequently joined Intel as Executive Vice President (EVP).
- Legal Basis: The lawsuit cites the Employment Contract, Non-compete Agreement, Non-disclosure Agreement, and the Trade Secrets Act.
Outlook, Risks, and Management Commentary
Management asserts a high probability that Lo is using, leaking, or transferring TSMC's trade secrets and confidential information to Intel.
