Business Context and Reporting Period

This Form 6-K, filed on February 13, 2025, reports the Fourth Quarter and Full Year 2024 preliminary earnings for ASE Technology Holding Co., Ltd. (ASE), a leading provider of outsourced semiconductor packaging and testing (ATM) and electronic manufacturing services (EMS). The results are unaudited and subject to audit adjustments. All financial figures are in New Taiwan Dollars (NTD) unless otherwise noted.

Key Financial Metrics

Capital Expenditures: Machinery capex for FY 2024 was approximately US$1.9 billion, an increase of US$1 billion versus 2023, driven by advanced packaging and testing investments.

Material Changes vs. Prior Period

• Revenue Growth: Full-year 2024 consolidated revenues grew 2% YoY. ATM revenues increased 3% YoY, while EMS revenues grew 1% YoY.
• Testing Segment: The testing business grew 9% YoY in 2024, with a significant 18% YoY increase in Q4 2024.
• Advanced Packaging: Leading-edge advanced packaging and testing revenues exceeded US$600 million in 2024 (approx. 6% of ATM revenue), up from US$250 million in 2023.
• Profitability: While gross profit margin improved to 16.3% in FY 2024 from 15.8% in FY 2023, operating income declined 3% YoY to NT$39.2 billion due to increased expenses and purchase price allocation (PPA) impacts.

Guidance, Outlook, and Risks

2025 Outlook: Management expects the ATM business to outgrow the logic semiconductor market, driven by leading-edge advanced packaging and testing. Leading-edge revenues are projected to increase by US$1 billion versus 2024, contributing 10% to overall growth. The general segment is expected to grow mid- to high-single digits YoY.

Q1 2025 Guidance:

• ATM Revenues: Expected to decline mid-single digits QoQ (in NTD).
• ATM Gross Margin: Expected to decline slightly more than one percentage point QoQ.
• EMS Revenues: Expected to decline slightly YoY (in NTD).
• EMS Operating Margin: Expected to decline 30 basis points YoY.

Risks and Contingencies:

• PPA Impact: Significant non-cash expenses related to purchase price allocation (ASE/SPIL and ASE/Infineon transactions) impacted reported earnings. Excluding PPA, FY 2024 Net Income was NT$36.9 billion (6.2% margin) vs. NT$32.5 billion reported.
• Market Risks: Cyclicality in the semiconductor industry, geopolitical tensions (ROC vs. PRC), US trade policy shifts, and foreign currency fluctuations.
• Operational Risks: Regulatory compliance, environmental liabilities, and competition in advanced technology introduction.

Investor Verification Checklist

• PPA Adjustments: Verify the impact of Purchase Price Allocation expenses on reported margins; management highlights significantly higher "excl. PPA" operating income and EPS.
• Currency Sensitivity: Confirm the impact of NTD exchange rate fluctuations on USD-denominated guidance and revenue comparisons.
• Advanced Packaging Mix: Validate the growth trajectory of the leading-edge advanced packaging segment (US$600M+ in 2024) as a key driver for future margins.
• Capex Utilization: Monitor the deployment of the US$1.9 billion machinery capex and its effect on future capacity and depreciation.
• Q1 Seasonality: Assess the projected Q1 2025 revenue decline against historical seasonal trends and the specific guidance for margin compression.
