ChipMOS results missed expectations with capacity utilization falling, dragging down profitability.
The company sees 1Q23E as the bottom for its performance, followed by a 2Q23E rebound. However, it says it believes the Memory industry may take longer to recover.
We believe ChipMOS is cheap if one looks through the cycle, and it is relatively unloved by the Street hence the expectations bar is set low.
