Insights

Semiconductor sector analyst

ChipMOS posts its strongest monthly YoY growth since 2021.

ChipMOS reported January 2026 revenue of NT$2,290.4 million (US$72.7 million), up 31.2% year over year and 4.0% month over month. This indicates a solid demand environment at the start of 2026.

The company links this strength to an improved semiconductor cycle and high-value memory demand for data center and AI applications. This ties revenue momentum to structurally important end markets, though sensitivity to broader macro and tech spending cycles remains.

Because this disclosure covers a single month, its longer-term significance depends on whether similar growth trends appear in subsequent quarters discussed in future company filings and reports.
