ASE Technology’s 30% ATM Growth: Is Advanced Packaging Rewriting The Story?

ASE Technology Holdings reported first quarter 2026 financial results marked by resilience amid typical seasonal patterns and ongoing structural adjustments in product mix. Consolidated net revenues reached NTD 173.7 billion, declining 2% sequentially but increasing 17% year-over-year in local currency terms, with a 4% sequential decrease and 22% annual increase on a U.S. dollar basis. Earnings per share stood at NTD 3.08 (fully diluted) and NTD 3.24 (basic). The company’s gross profit totaled NTD 34.8 billion, yielding a 20.1% margin—up 0.6 percentage points sequentially and 3.3 percentage points year-on-year—primarily driven by higher Advanced Packaging and Testing Manufacturing (ATM) revenues, increased factory utilization, and foreign exchange effects. The ATM segment contributed 65% of consolidated revenue and 91% of operating profit, underscoring its dominant role. ATM revenues grew 2% sequentially and 30% annually to NTD 112.4 billion, setting a new quarterly record.
