Investor Verification Checklist
- Revenue Quality: Verify the sustainability of the 50% sequential revenue jump in the EMS segment and its impact on overall margins.
- One-Time Gains: Assess the impact of the NT$1,565 million gain on revaluation of a disposal subsidiary on net income; exclude this to evaluate core operating performance.
- Customer Concentration: Monitor the high concentration of EMS revenue (86% from top 5 customers) and potential risks associated with client dependency.
- Cash Flow vs. CapEx: Review the net cash decrease of NT$5,935 million in 4Q20 against heavy capital expenditures (US$379 million) to ensure liquidity remains robust.
- Margin Pressure: Investigate the sequential decline in consolidated gross margin (15.7%) despite revenue growth, specifically driven by the EMS segment.
