Apple’s key chip supplier TSMC races to recover after crippling computer virus..

• The incident underscores the global nature of the technology supply chain, in which companies like Apple and Qualcomm Inc. depend on hundreds of suppliers around the world. This is the first time a virus had ever brought down a TSMC facility.
• Taiwan Semiconductor Manufacturing Co., which makes chips for the iPhone and other devices, is recovering from a debilitating computer virus but 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 expects full recovery on Monday.
•  The Taiwanese company said the incident, which comes as it ramps up chipmaking for Apple Inc.’s next iPhones, would delay shipments, without specifying which customers would be affected. Its shares fell more than 1 percent in Taipei.
• The chipmaker estimated that third-quarter revenue would be cut by about 3 percent from a previously forecast $8.45 billion to $8.55 billion, while gross margin would slip by about 1 percentage point. It maintained its 2018 forecast of boosting revenue by high single digits in US dollar terms.
