What's Going On With Taiwan Semiconductor Stock Tuesday?

Arizona Plant Profit Jumps

The Arizona operation generated about 18.8 billion New Taiwan dollars ($589.2 million) in first-quarter profit. That included roughly 16.9 billion New Taiwan dollars ($529.7 million) in investment income.

Arizona Expansion Accelerates

Money UDN also reported that construction of Taiwan Semiconductor’s third Arizona wafer fab began in May. The facility will support 2-nanometer and A16 production, with mass production potentially starting around 2028.

Meanwhile, the second Arizona fab, designed for 3-nanometer production, is complete. Equipment installation is expected to begin in the second half of 2026, with mass production targeted for the second half of 2027.

Chairman C.C. Wei previously said the company would add $100 billion to its U.S. investment plans, bringing its total planned commitment to $265 billion.
