- Assess the impact of the NT$3,790 million foreign exchange loss on future earnings given currency volatility.
- Review the concentration risk: The top 5 customers accounted for 41% of ATM revenues and 71% of EMS revenues.
- Monitor the high level of capital expenditures (US$779 million in 3Q25) relative to operating cash flow.
