Insights

Semiconductor revenue analyst

Solid YoY growth with flat-to-slightly lower sequential trend.

ASE Technology posted October consolidated revenue of NT$60,231 million, modestly below September (-0.5%) but up 6.7% year over year. In USD terms, revenue was $1,980 million, showing similar dynamics (-0.8% seq, +12.1% YoY).

The ATM segment (assembly, testing and material) was the growth driver at NT$36,039 million, rising 3.0% sequentially and 22.9% YoY; in USD, $1,185 million (+2.7% seq, +29.1% YoY). This suggests continued end-market demand for outsourced packaging and testing in October 2025.

Monthly figures can be volatile and are unaudited; actual quarterly trends will depend on subsequent months and currency effects. The update is informative but does not by itself indicate a change in broader outlook.
