Strong Earthquake in Kumamoto, TSMC's JASM Inventory Completed, Normal Power and Water Supply, Production Line Adjustment Underway

A magnitude 7.1 strong earthquake occurred in Kumamoto, Japan, on the afternoon of the 28th. TSMC (2330-TW)(TSMM-US) stated on the 29th that the water supply, power, and safety systems in the Kumamoto JASM plant area are operating normally. Inspection and correction of production equipment are ongoing, but due to the large amplitude of the earthquake, it is expected to take some time to adjust and correct. Resources have been dispatched for support, and currently, there is no shortage of raw materials.

TSMC stated that after taking inventory, resources have been dispatched to support JASM, and a comprehensive review of the impact of this earthquake is underway. Communication with customers is being maintained. As for the JASM plant construction site currently under construction, it has not been affected. After confirming safety, construction has resumed today.

After a magnitude 7.1 strong earthquake in Kumamoto, Japan, there were several aftershocks of considerable magnitude. The maximum seismic intensity recorded at the TSMC JASM wafer plant was 5.

TSMC stated that prioritizing personnel safety, JASM, in accordance with internal procedures, immediately activated relevant safety precautions during the earthquake. Personnel evacuation was conducted in the first instance, and post-earthquake damage inspection of the JASM plant area has been completed, confirming that the structure and personnel are safe.
