Key Takeaways
ASX's ATM revenues rose 36% to a record TWD 126.1 billion in the second quarter of 2026.
ATM gross margin rose to 27.3% as higher utilization and LEAP mix improved operating leverage.
ASX expects ATM gross margin to exceed 30% in Q4 2026 as LEAP and testing services expand.
ASE Technology Holding (ASX - Free Report) is seeing strong growth in its ATM business, supported by demand for advanced packaging and testing services. In the second quarter of 2026, ATM revenues reached a record TWD 126.1 billion, up 36% year over year and 12% sequentially. Higher loading across both LEAP and general services helped ATM revenues come in above management’s expectations. For 2026, ASX expects ATM revenues to grow 35% year over year.
Strong ATM growth is improving ASX’s profitability. ATM gross profit increased to TWD 34.5 billion in the second quarter, while gross margin rose 5.4 percentage points year over year to 27.3%. The improvement was mainly driven by higher operating leverage and a better revenue mix, including a higher contribution from LEAP services. ATM operating profit increased 124% year over year, while operating margin rose 6.2 percentage points to 15.7%.
The ATM business is also becoming a larger contributor to ASX’s overall profits. In the second quarter, ATM accounted for 66% of consolidated revenues, up from the year-ago quarter's 61% of revenues. Similarly, ATM accounted for 94% of operating profit, up from the year-ago quarter's 87% of operating profit. Management attributed much of this change to the growth of LEAP services over the past few years. Higher utilization and continued investment in automation are key factors that are helping improve operating efficiency.
ASX expects ATM profitability to improve further in the second half of 2026. For the third quarter, the company expects ATM revenues to increase 11-13% sequentially, with gross margin between 28% and 29%. Management also expects fourth-quarter 2026 ATM gross margin to exceed its current structural ceiling of 30%, supported by the growing contribution from LEAP and testing services. The Zacks Consensus Estimate for 2026 and 2027 indicates revenue growth of around 27.9% and 22.5%, respectively.
How Competitors Fare Against ASE Technology
