Berkshire Hathaway Discloses $4.1 Billion Stake in Apple Chipmaker TSMC

Berkshire Hathaway has disclosed a $4.1 billion stake in Apple chipmaker TSMC, reports Reuters. Taiwan Semiconductor Manufacturing is the exclusive supplier of Apple's A-series and M-series chips used to power the iPhone, iPad, and Mac. Notably, Berkshire Hathaway also has a $126.5 billion stake in Apple.

In a Monday regulatory filing describing its U.S.-listed equity investments as of Sept. 30, Berkshire said it owned about 60.1 million American depositary shares of TSMC.

News of the investment caused TSMC shares to soar, closing up 7.9% on Tuesday in Taiwan. Although company shares recently hit a two year low due to a sharp slowdown in global chip demand, TSMC is the world's leading supplier of semiconductors, an industry that is expected to see continued growth.


Recent reports suggest TSMC may be planning to build a second multibillion dollar factory in Arizona. The second plant will be located north of Phoenix, next to a $12 billion plant TSMC committed to building in 2020. It's believed that the new plant could be used to make 3nm transistors.
