Material Changes vs. Prior Period
- Revenue Growth: Consolidated revenues grew 7% YoY, driven primarily by the ATM segment which grew 20% YoY. The EMS segment declined 7% YoY.
- Segment Performance: ATM testing revenues grew 32% YoY. Leading-edge advanced packaging and testing now represent over 10% of ATM revenues, up from 6% in full-year 2024.
- Profitability: While operating income increased 13% YoY, net income attributable to shareholders decreased 3% YoY. This divergence is largely due to Purchase Price Allocation (PPA) expenses of NT$772 million in Q2 2025 (related to prior acquisitions) and a non-operating loss of NT$939 million.
- Excluding PPA: Adjusted net income (excluding PPA) was NT$8,288 million, down 8% YoY. Adjusted operating margin was 7.3%.
- Liquidity: Cash and cash equivalents decreased by NT$4.3 billion quarter-over-quarter. Total interest-bearing debt increased by NT$8.5 billion QoQ.
Guidance, Outlook, and Risks
Q3 2025 Outlook (based on 1 USD = 29.2 NT$):
- Consolidated Revenue: Expected to grow 12-14% QoQ in USD terms (6-8% in NT$ terms).
- Gross Margin: Expected to decrease by 1.0 to 1.2 percentage points QoQ.
- Operating Margin: Expected to decrease by 0.1 to 0.3 percentage points QoQ.
- ATM Segment: Revenue expected to grow 9-11% QoQ in USD terms; gross margin expected to decrease 0.9-1.1 percentage points QoQ.
- EMS Segment: Revenue expected to grow 18-20% QoQ in USD terms; operating margin expected to increase 0.3-0.5 percentage points QoQ.
Management Commentary: Management anticipates continued momentum in 2H2025 driven by AI proliferation and general semiconductor recovery. Leading-edge solutions are expected to contribute US$1 billion in incremental revenue growth in 2025.
Risks and Contingencies:
- Geopolitical: Strained relations between the Republic of China and the People's Republic of China; shifts in US trade policies.
- Market: Cyclicality of the semiconductor industry; competitive pressures.
- Operational: Forex fluctuations (assumed rate of 29.2 NT$/USD for Q3 vs 31.2 in Q2); tariff uncertainties; environmental regulations.
Key Investor Verification Points
- PPA Impact: Verify the sustainability of earnings excluding the one-time Purchase Price Allocation (PPA) charges of ~NT$770 million per quarter, which significantly impacted net income.
- EMS Recovery: Monitor the turnaround in the EMS segment, which has declined for two consecutive quarters (-7% YoY in Q2).
- Margin Compression: Assess the drivers behind the projected Q3 gross margin decline of 1.0-1.2 percentage points despite revenue growth.
- Debt Levels: Review the increase in total interest-bearing debt to NT$240 billion and the rising net debt-to-equity ratio (0.52) against cash flow generation.
- Currency Sensitivity: Evaluate the impact of the assumed exchange rate shift from 31.2 (Q2) to 29.2 (Q3) on reported USD revenue growth.
