Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 5% to NT$23.9 billion, driven by a 27% surge in Assembly services (memory rebound) and 14% growth in Testing services. This offset a 20% decline in Display panel driver services due to weak market demand and inventory adjustments.
- Profitability Decline: Net profit dropped 62% to NT$551 million. Gross margin contracted to 10.8% from 13.0% due to higher raw material costs (gold prices), increased electricity rates, and lower capacity utilization in the display segment.
- Non-Operating Impact: Significant foreign exchange losses of NT$459 million (vs. gains of NT$243 million in 2024) and a loss from associates of NT$143 million materially reduced net income.
- Segment Performance:
- Testing: Margin improved to 22.1%.
- Assembly: Margin improved to -1.6% (from -11.2%) due to volume recovery.
- Display (LCDD): Margin collapsed to 7.5% (from 22.5%) due to price competition and volume drop.
- Bumping: Margin declined to 18.0% due to high gold costs.
Guidance, Outlook, and Risks
Outlook & Strategy:
- Management expects demand for high-value memory solutions (data center/AI) to sustain growth, while consumer end markets remain soft.
- Focus on expanding logic/mixed-signal portfolios (PMIC, AI ASICs) and automotive applications to offset display weakness.
- Capacity utilization rates for memory/logic testing and assembly improved to 66% and 67% respectively in 2025.
Key Risks & Contingencies:
- Geopolitics & Tariffs: Potential US tariffs on Taiwanese semiconductors and Section 301 investigations could disrupt supply chains and reduce revenue.
- Customer Concentration: Top 5 customers accounted for 61% of 2025 revenue.
- Commodity Prices: Volatility in gold prices directly impacts bumping service margins; electricity rate increases in Taiwan raise operational costs.
- Debt Levels: Significant indebtedness (NT$12.8 billion long-term) limits cash flow flexibility; 83% of debt is variable rate.
Investor Verification Checklist
- Display Segment Recovery: Verify if the 20% revenue drop in the Display panel driver segment is a temporary inventory correction or a structural decline due to Mainland China competition.
- Gold Price Hedging: Assess the company's ability to pass through rising gold costs to customers in the bumping segment to protect margins.
- FX Exposure: Confirm the impact of the NT$459 million foreign exchange loss and the company's hedging strategy given 52% of revenue is USD-denominated.
- Debt Servicing: Review the maturity profile of the NT$12.8 billion long-term debt and the impact of rising interest rates on cash flow.
- Capacity Utilization: Monitor if the improved utilization rates in memory/logic segments can be sustained to offset fixed costs in the underutilized display segment.
