TSMC Details Impact of Computer Virus Incident
TSMC today provided an update on the Company's computer virus outbreak on the evening of August 3, which affected a number of computer systems and fab tools in Taiwan. The degree of infection varied by fab. TSMC contained the problem and found a solution, and as of 14:00 Taiwan time, about 80% of the company's impacted tools have been recovered, and the Company expects full recovery on August 6.
TSMC expects this incident to cause shipment delays and additional costs. We estimate the impact to third quarter revenue to be about three percent, and impact to gross margin to be about one percentage point. The Company is confident shipments delayed in third quarter will be recovered in the fourth quarter 2018, and maintains its forecast of high single -digit revenue growth for 2018 in U.S. dollars given on July 19, 2018. Most of TSMC's customers have been notified of this event, and the Company is working closely with customers on their wafer delivery schedule.
