Taiwan Semiconductor’s shares climbed on Tuesday after the company secured a one-year U.S. export license allowing continued imports of American chipmaking equipment for its China operations. The license, effective through early 2027, removes near-term regulatory uncertainty and underpins the recent rally that began late last week. Trading volume in New York jumped 30% versus its 30-day average, reflecting heightened investor confidence in the company’s ability to maintain production momentum across all major fab sites.

Shares of Taiwan Semiconductor reached a fresh all-time high this week, extending a year-to-date rally driven by surging demand for advanced AI chips. The stock has risen approximately 45% over the past 12 months, outperforming the broader semiconductor index by nearly 20 percentage points. Several Wall Street firms, including Goldman Sachs, have upgraded their ratings in recent days, citing a robust product roadmap for 3-nanometer and 2-nanometer process nodes and sustained foundry capacity utilization above 95%.

Taiwan prosecutors recently filed additional indictments in a trade-secrets case involving the company’s technology, targeting the local unit of a major equipment supplier and three individuals. While the legal proceedings have drawn headlines, industry analysts believe the impact on Taiwan Semiconductor’s operations will be minimal. The company’s core IP portfolio spans over 25,000 patents, and management has reiterated that no material disruptions to fab operations or customer engagements are anticipated during the multi-year litigation process.
