TSMC third-quarter revenue totals about NT$1.494 trillion from its July to September monthly reports

Adding TSMC's three monthly revenue reports gives third-quarter 2026 revenue of about NT$1,494.25 billion: July NT$467.58 billion, August NT$514.81 billion and September NT$511.86 billion. That is above the top of the US$44.6-45.8 billion range guided on July 16, and the monthly pattern implies the quarter came in above guidance before the October 15 call. This total is our own sum of TSMC's reported monthly figures, not a company-reported quarterly number.
