Change record

What changed

  • September revenue was NT$511.857 billion, down 0.6% from August and up 54.6% from September 2025.
  • January-September 2026 revenue totaled NT$3,898.727 billion, 41.1% above the comparable 2025 period.
  • The company release reports consolidated revenue; it does not isolate CoWoS utilization, advanced-packaging throughput, HBM allocation or customer qualification.

Public interpretation

Why it matters

The update confirms unusually strong foundry demand through the third quarter, but it does not resolve the packaging-capacity evidence gap. ConstraintAlpha should keep total revenue separate from proof of qualified CoWoS or HBM supply.
