TSMC pointed out that it was infected with computer viruses in the evening of the third day, affecting some computer systems and factory machines in Taiwan. The degree of virus infection varies from factory to factory. TSMC has controlled the scope of this virus infection and found a solution. As of the point, about 80% of the affected machines have returned to normal. TSMC expects that all affected machines will return to normal before August 6.
TSMC said that the virus infection incident will lead to delays in wafer shipments and increased costs. The impact on TSMC's third quarter revenue is about 3%, and the gross profit margin impact is about one percentage point. TSMC is confident. The number of wafer shipment delays in the third quarter will be replenished in the fourth quarter, and the full-year outlook will continue to maintain the high single-digit growth stated in July 19 in US dollars.
TSMC said that most of the company's customers have received notice of relevant events. TSMC is also working closely with customers to communicate their wafer delivery schedules. TSMC will communicate detailed information with individual customers in the next few days.
TSMC said that measures have been taken to make up for this security issue, and information security measures will be further strengthened.
