TSMC boosts Arizona fab investment by $100B after strong second quarter

Taiwan Semiconductor Manufacturing Co. today posted second-quarter results that handily topped analyst expectations.

The company also announced plans to expand its fab complex in Arizona. TSMC intends to build at least four additional facilities at a cost of $100 billion, which will bring its total investment in the site to $265 billion.

The chipmaker’s profit surged 77% year-over-year in the second quarter, to 706.56 billion New Taiwan dollars, or about $21.89 billion. Analysts expected NT$632.64 billion. The profitability boost was partly driven by a 36% year-over-year top-line increase. TSMC closed the quarter with sales of $39.45 billion, a hair above the consensus estimate.

About two-thirds of the company’s revenue came from its high-performance computing segment, which includes data center chips. The segment is also the fastest growing of TMSC’s core businesses: Its revenue rose 20% on a quarter-over-quarter basis. Sales of smartphone chips, the company’s second-largest revenue source, dropped 4%.
