ASE Technology Holding Co., Ltd. Q3 2026 Earnings Recap

Shares fell 10.1% after earnings, despite record revenue and sharply higher margins. The transcript points to a likely concern that demand is outstripping available capacity: ATM ran near full utilization, and management said it could not supply all demand for LEAP and much of non-LEAP. The Q4 outlook is not included in the transcript provided, so a specific guidance disappointment cannot be confirmed.

Key Takeaways

• Consolidated revenue reached a record TWD 244.2 billion, up 28% sequentially and 45% year over year; net income was TWD 27 billion, up 28% and 148%, respectively.
• Gross margin rose to 22.1%, up 1.1 percentage points sequentially and 5 points year over year. Operating margin increased to 13.6%, up 2.5 points sequentially and 5.8 points year over year.
• ATM revenue was a record TWD 151.5 billion, up 20% sequentially and 51% year over year. ATM gross margin reached 30.6%, with management attributing the improvement to higher loading and a richer LEAP mix.
• Capacity was tight: ATM ran at or near full utilization, while demand exceeded supply for LEAP and much of non-LEAP. Management expects operating expenses to keep rising in absolute terms, though near the current-year range as a share of revenue.
• The transcript cuts off before the Q4 outlook. Management did say it now expects a full-year effective tax rate of 16%–17%.
