Taiwan Semiconductor Manufacturing Company Limited (NYSE:TSM) has been forced to satisfy Western political demands and diversify the supply chain. As part of this, it is building expensive foundries outside of Taiwan, most notably in Arizona, Japan, and Germany. In the Q1 2026 update, TSM management announced they are pushing their full-year 2026 capital expenditures to the absolute high end of their $52 billion to $56 billion range. Building advanced fabrication plants in the United States and Europe is mathematically less efficient. Internal construction and operational costs in Arizona are estimated to be 4x to 5x higher than building identical fabs in Hsinchu or Tainan. TSM management explicitly admitted that overseas fab expansions and the initial ramp-up of next-generation nodes will trigger an immediate 2% to 3% gross margin dilution starting in the latter half of 2026 and extending into 2027.
