Taiwanese chipmaking champion TSMC has revealed that a January earthquake will cost it millions. The January 21st tremblor and its aftershocks peaked with a shake that rated 6.4 on the Richter scale and was followed by several aftershocks. At the time, TSMC asked workers to leave its buildings to ensure their safety.

TSMC reported a January revenue of NT$293.2 billion (US$8.9 billion) on Monday, marking the second-highest single-month revenue in the company’s history. The chipmaker said the earnings represent a 5.

TSMC, the world's biggest contract chipmaker, said on Monday its first-quarter revenue would be closer to the lower end of its guidance, as it expects a $161 million impact from an earthquake that rocked the island in January.

TSMC continued its run of robust revenue growth in January, but Q1 sales are expected to hit the lower-end of a previous guidance.
