Han's CNC (3200.HK) tumbled more than 8% in Hong Kong trading to HK$126.40. The company previously announced that first-half net profit is expected to reach 9 billion to 10 billion yuan, representing a year-over-year increase of 241%-280%. Revenue is projected to grow by more than 100% compared to the same period last year.

The strong earnings forecast was driven by robust demand for high-end PCB equipment fueled by AI computing power expansion. Despite the positive guidance, shares declined sharply during regular trading hours without an immediate company-specific catalyst explaining the selloff.
