Most Popular Narrative: 24% Undervalued

The market appears to be assuming further robust revenue growth driven by the ongoing AI and data center investment wave, with expectations for high demand for advanced IC substrates and PCBs tied to next-generation processors. However, management notes that while qualification and ramp-up of new facilities are underway, revenue timing is highly uncertain and actual order conversion from AI and data center sectors may be slower and more volatile than consensus forecasts, which could pressure future revenue realization.
