Taiwan Semiconductor Manufacturing Co., which makes chips for the iPhone and other devices, has revealed details of its recovery from a debilitating computer virus, and warned of delayed shipments and reduced revenue because of the impact on its factories.
TSMC said that 80 percent of the fabrication tools affected by a virus outbreak Friday evening had been restored, and that it expected a full recovery on Monday, an emailed statement shows. The Taiwanese company said the incident, which came as it ramps up chipmaking for Apple Inc.'s next iPhones, would delay shipments but did not specify which customers would be affected.
The chipmaker estimated that third-quarter revenue would decline by about 3 percent and operating margins by about 1 percentage point, according to the Sunday statement. It maintained its 2018 forecast of boosting revenue by high single digits in U.S. dollar terms.
