Insights

Senior Corporate Finance Analyst

October revenues show slight sequential dip but clear year-over-year growth, led by the ATM segment.

The company reported consolidated net revenues of NT$60,231 million (US$1,980 million) for Oct 2025, a -0.5% sequential change in NT$ and -0.8% in US$, while year-over-year figures rose +6.7% in NT$ and +12.1% in US$. The ATM assembly, testing and material business delivered NT$36,039 million (US$1,185 million), a +3.0% sequential rise and +22.9% year-over-year increase.

These figures imply stable monthly demand with modest month-to-month variability alongside stronger annual growth. Key dependencies include continued contribution from the ATM segment and currency translation effects between NT$ and US$. Monitor upcoming monthly releases and quarterly filings for confirmation of trends over the next 1–3 months and any management commentary clarifying drivers of the sequential dip and the pronounced ATM year-on-year gain.
