Kingboard Chemical’s Explosive June Performance
Kingboard Chemical Holdings (SEHK:148) posted an extraordinary 135.43% share price increase in June, propelling its cumulative AI‑materials rally to a staggering +612.12% since the stock was first highlighted by ProPicks AI in February 2025. The surge followed two simultaneous announcements: a HK$11.77 bn (approximately US$1.5 bn) stake sale of its laminate subsidiary and the company’s fifth product price increase of 2026, both aimed at capitalising on accelerating AI server demand.
The proceeds from the stake sale are earmarked exclusively for expanding printed‑circuit‑board (PCB) capacity and funding research‑and‑development. Kingboard is scaling its Thailand production from 600,000 sheets per month toward a target of 1.8 million sheets per month, reflecting a three‑fold capacity expansion to meet AI‑grade demand.
Kingboard is a leading global producer of FR‑4 laminate—the standard substrate for the majority of printed circuit boards—manufacturing not only the laminate but also copper foil, glass fabric, and epoxy resin, sourcing more than 70% of its raw materials across over 60 factories in China and Thailand. In 2025 the company generated $5.5 bn in revenue. This year it introduced HVLP3 copper foil and ultra‑thin VLP copper foil specifically designed for AI server GPU motherboards and IC substrate packaging, positioning its products at the core of every new data‑centre rack.
The five price hikes across all FR‑4 and PP product lines in 2026 were driven by rising copper costs and tightening glass‑cloth supply, giving Kingboard substantial pricing leverage as AI server demand accelerates. The company’s vertically integrated model, combined with the fresh capital injection, underpins a multi‑year shift toward premium AI‑server materials.
ProPicks AI’s early identification of Kingboard in February 2025 proved prescient; the stock’s total return has compounded to +612.12% by June 2026, outpacing broader AI‑related equities that also posted double‑digit gains during the month. The broader AI rally saw other notable performers such as Marvell Technology (+41.54% in June), Veeco (+39.14% in June), Tokyo Electron (+45.74% in June), and Megaport (+43.28% in June), but Kingboard’s triple‑digit surge stands out as the most dramatic material‑sector move.
Outlook
With the $1.5 bn capital now directed toward capacity expansion and R&D, and five confirmed price hikes already in place for 2026, Kingboard is positioned to capture a growing share of the AI‑server materials market. The company’s integrated supply chain and pricing power suggest continued upside as AI data‑centre construction accelerates.
