TSMC stock
On October 22, 2026, reports revealed that Taiwan Semiconductor Manufacturing Co. (TSMC) is exploring alternatives to rare--earth components in its factory equipment to mitigate operational risks stemming from Chinese export controls. TSMC has asked equipment and tool suppliers to identify and qualify alternative motor designs and mechanical components that eliminate dependence on Chinese--controlled rare--earth permanent magnets, which are critical for motion control in highly automated wafer fabrication machinery. The proactive initiative aims to shield TSMC's advanced semiconductor manufacturing lines from equipment maintenance bottlenecks and supply disruptions as geopolitical trade restrictions tighten.
