• Profitability: 4Q24 net income declined slightly to NT$9,312 million from NT$9,392 million in 4Q23 and NT$9,733 million in 3Q24. Full-year 2024 net income rose 2.4% YoY to NT$32,483 million.

Management Commentary Highlights:

• Customer Concentration: The top five customers accounted for 44% of total revenue in 4Q24 (ATM basis), while the top five EMS customers accounted for 72% of EMS revenue.
• Operational Adjustments: The company adjusted its revenue sourcing calculation in 4Q24 to focus on direct customers rather than end customers, resulting in retrospective adjustments to prior period customer metrics.
• Capital Allocation: 4Q24 CapEx was heavily weighted toward packaging (US$321 million) and testing (US$290 million) operations.

Investor Verification Checklist

• Retrospective Adjustments: Verify the impact of the business combination purchase price allocation and the change in customer revenue sourcing methodology on historical comparability.
• FX Sensitivity: Assess the impact of the NT$2,787 million foreign exchange loss in 4Q24 on future earnings given the volatility of the USD/NTD exchange rate.
• Customer Concentration: Review the specific identities and stability of the top customers, particularly in the EMS segment where the top five represent 72% of revenue.
• Margin Pressure: Monitor the divergence between the expanding ATM gross margin (23.3%) and the contracting EMS gross margin (8.3%) to understand overall profitability drivers.
• Capital Intensity: Evaluate the sustainability of the US$1.876 billion full-year CapEx relative to cash flow from operations (NT$90,788 million).
