A Chinese company most people have never heard of has quietly become one of the hottest stocks in Asia. Kingboard Laminates Holdings, a Hong Kong-listed manufacturer of copper-clad laminates, has seen its shares surge more than 500% from recent lows as investors pile into what they see as a critical chokepoint in the AI hardware supply chain.
The numbers behind the rally
Revenue for 2025 climbed 10% year-over-year to HK$20.4 billion. Net profit surged 85% to HK$2.49 billion.
Specialty fiberglass, one of Kingboard’s key product lines, saw profit grow by 70% in 2025 alone. The driver: tightening supply of electronic glass fiber cloth and AI-specific materials that command premium pricing.
Shares surged roughly 12.8% in a single session during a broader PCB sector rally in 2026, with year-to-date gains peaking around 83% at one point.
