TSMC Arizona reported a first-half 2026 profit of NT$36.066 billion. This performance represents a 662.8% increase over the previous year. The facility is now the highest-earning overseas manufacturing subsidiary within the TSMC group.
Second-quarter profits for the plant reached NT$17.259 billion. This figure marks a 307.8% increase from the same period in 2025.
The Arizona expansion drove a 200% surge in Taiwan's approved outbound investments during the first seven months of the year. While international growth typically pressures gross margins, the U.S. plant's strong profitability validates the company's diversification strategy.
