As of June 17, 2026, according to Gate stock data, Hong Kong-listed KINGBOARD HLDG (00148) was trading at $115.4, up 16.5% for the day. During the session, the stock briefly touched $120, setting a new all-time high. This surge is not an isolated event—since the start of 2026, the stock has gained approximately 83% year-to-date. Against the backdrop of rapidly expanding AI computing infrastructure, what structural shifts in the industry does KINGBOARD’s rally reveal?
Why Copper-Clad Laminate Has Become the Key Bottleneck in the AI Server Supply Chain
Copper-clad laminate (CCL) is the core substrate for printed circuit boards (PCBs), made by laminating copper foil onto a fiberglass base. It serves as the foundation for mounting all chips, capacitors, and connectors. The rising compute density of AI servers is directly driving demand for high-performance CCL: the average number of layers in AI server PCBs has jumped from 18 in 2023 to 32 in 2025—a 78% increase in just two years. As layer counts and signal rates climb, the requirements for low-loss, high-frequency transmission, and thermal management capabilities in base materials become increasingly stringent.
As a global leader in CCL manufacturing, KINGBOARD occupies a pivotal position in this segment. Its product portfolio spans from standard copper-clad boards to high-frequency, high-speed materials tailored for AI applications. In 2024, KINGBOARD held the largest global market share for CCL. As AI servers demand ever more complex PCBs, upstream CCL materials are both the first to feel supply chain pressure and the first to benefit from surging demand.
How Tight Electronic Fiberglass Cloth Supply Is Driving Up Upstream Material Prices
The immediate driver of this price rally is a shortage of electronic-grade fiberglass cloth. Data shows that since the start of the year, average selling prices for this material have risen by 60% to 95%. In June alone, the average price per meter increased by RMB 0.70 to 0.95, up from May’s RMB 0.55 to 0.75.
Several factors are constraining supply: major suppliers need time to ramp up production, weaving machine capacity is limited, and some peers have shifted capacity toward higher-margin AI-related fiberglass cloth. Industry analysis suggests that HVLP4 copper foil will become a new major supply constraint in the second half of 2026, with this year’s market shortfall expected to reach 1,500 tons and potentially widening to 2,500 tons by 2027. Only a handful of suppliers with mass production capabilities in advanced copper foil, fiberglass cloth, and related materials will have significant bargaining power amid this supply-demand imbalance.
This supply dynamic is feeding directly into CCL prices. At the end of 2025, CCL was priced at about RMB 150 to 160 per sheet; prices have since climbed to RMB 180 to 190. Institutions forecast that the average annual CCL price in 2026 will rise nearly 76% year-over-year to RMB 220 per sheet, with spot prices potentially rising another 30% in the second half, reaching RMB 240 per sheet by year-end.
How Financial Data Supports the Market’s Revaluation of KINGBOARD
Ultimately, rising prices are reflected in financial performance. For the full year 2025, KINGBOARD Group reported revenue of HKD 45.375 billion, up 5% year-over-year; profit attributable to shareholders surged 207% to HKD 4.985 billion. Earnings before interest, taxes, depreciation, and amortization (EBITDA) rose 63% to HKD 9.548 billion, while pre-tax profit increased 131% to HKD 6.363 billion.
Subsidiary Kingboard Laminates (01888.HK) also delivered strong results, with 2025 revenue reaching HKD 20.4 billion, up 10% year-over-year, and net profit soaring 85% to HKD 2.49 billion. Notably, the specialty fiberglass product line saw annual profit growth of 70% in 2025.
The 85% net profit growth versus a share price increase of over 500% from the lows highlights the market’s expectation of sustained growth in the coming years—not just a recognition of past performance.
How Vertical Integration Amplifies Competitive Advantage During Price Surges
KINGBOARD’s unique edge lies in its vertically integrated supply chain. The company’s operations span the entire chain—from fiberglass yarn and cloth to copper foil and copper-clad laminate. This structure gives it far greater ability than peers to pass on costs and exercise pricing power when raw material prices rise.
When upstream materials like electronic fiberglass cloth and copper foil are in short supply, vertical integration enables KINGBOARD to better control costs, secure supply, and pass price increases downstream. In April 2026, a KINGBOARD subsidiary officially announced a price hike, raising prices by 10% for all thicknesses of FR-4 copper-clad boards and PP prepregs. Downstream customers had virtually no room to negotiate, as all clients were subject to the same unified pricing.
The company is also actively expanding new production capacity for high-frequency laminates and thick copper materials for AI applications. In 2025, KINGBOARD commissioned a new factory in Guangdong dedicated to ultra-thin, high-frequency laminates for AI data center motherboards. This strategic capacity expansion positions the company to capitalize on the explosive demand from AI infrastructure buildouts.
What Do Upward Target Price Revisions Reveal About Industry Expectations?
Market optimism toward KINGBOARD is reflected in institutional ratings. In early June, Citibank raised its target price for KINGBOARD HLDG from HKD 65 to HKD 90, maintaining a "Buy" rating, citing the greater-than-expected surge in electronic fiberglass cloth prices. Institutions forecast a 2027 price-to-earnings ratio of around 10x.
This is not the first upward revision. Back in May, Citi had already raised its target price from HKD 48 to HKD 65 and increased its earnings forecasts for 2026–2028 by 50% to 61%. Guosen Securities also initiated coverage of Kingboard Laminates with an "Outperform" rating.
From a broader perspective, the AI server PCB industry is undergoing a shift from labor-intensive to capital- and technology-intensive operations. Prismark forecasts that global PCB output value will reach $94.661 billion by 2029, with a compound annual growth rate of 5.2% from 2024 to 2029. In this structural growth cycle, the scarcity value of upstream materials is being repriced by the market.
Valuation and Risks: What Is the Market Trading After a 500% Rally?
After a more than 500% rally from the lows, the market faces a critical question: does the current valuation already fully reflect future growth expectations?
From a financial standpoint, Kingboard Laminates’ current P/E is already at a high level. While 85% net profit growth is impressive, a 500% share price increase suggests the market has priced in several years of future growth in advance. If AI capital expenditures slow, or if new laminate capacity comes online faster than anticipated, the pricing power driving profit margins could weaken.
From an industry competition perspective, as more suppliers pivot to AI-optimized products, the risk of commoditization in AI-grade laminates could gradually erode pricing power. Additionally, downstream giants like NVIDIA have begun directly coordinating upstream material supplies, bypassing some CCL manufacturers to work directly with upstream suppliers. This trend could reshape traditional supply chain power dynamics, potentially squeezing margins for intermediaries.
On the supply side, the shortage of advanced CCL is expected to persist through 2027, making a near-term resolution to the supply-demand imbalance unlikely. However, supply tightness is a double-edged sword—it drives prices higher, but may also accelerate capacity expansions by competitors and the development of substitute materials.
Conclusion
KINGBOARD’s record high on June 17 is essentially the result of the AI computing infrastructure boom rippling upstream to the materials segment. Tight electronic fiberglass cloth supply has driven CCL prices steadily higher, while the company’s vertically integrated structure provides a strong cost transmission advantage—together forming the fundamental basis for this round of value re-rating. The 207% year-over-year net profit growth in 2025 validates the price hike thesis, and institutional target price upgrades to HKD 90 reflect confidence in the continuation of this trend.
However, after a short-term rally of over 500%, current valuations already factor in expectations for sustained high growth over the next several years. The sustainability of AI capital expenditures, the pace of new capacity coming online, and the impact of downstream customers directly sourcing upstream materials—all are key variables that will shape the stock’s trajectory. While the scarcity premium in upstream materials remains supported in the face of a persistent supply-demand gap, the market is becoming increasingly sensitive to shifts in expectations.
