Taiwan's government is reportedly moving to restrict chip-related exports to China, drawing attention to TSMC, which reported FY2024 revenue of approximately $2.9T NTD (+33.9% YoY) with exceptional margins (56.1% gross, 40.0% net) and $44.67 diluted EPS. China has historically represented a meaningful share of TSMC's wafer revenue, so any tightening of export rules introduces a direct top-line risk even as the underlying business remains near peak operational efficiency.

The key tension is whether incremental restrictions are incremental noise or the start of a more structural decoupling that impairs TSMC's revenue mix. Investors should watch for formal policy announcements from Taipei, any guidance update from TSMC management on China exposure, and whether US policy pressure is driving the timeline — all of which would sharpen the risk/reward from current levels.
