- Stock locked limit-up at NT$207.5, up 9.78%, on AI server demand
Key Takeaways:

Nanya Plastics confirmed cumulative price increases on its electronic materials have exceeded 100% this year, sending its shares to the daily limit.
Nanya Plastics confirmed Friday that cumulative price increases on its electronic materials — copper-clad laminate, fiberglass cloth and copper foil — have topped 100% this year, as AI server demand from US hyperscalers strains upstream supply. The company raised prices in stages through negotiations with individual customers rather than a single announcement, Nanya said, according to Taiwan's Economic Daily News.
Fiberglass cloth faces the most severe shortage, followed by copper foil, Nanya said. A leaked document showing a 20% price increase on substrates and base materials from Sept. 1 was email content from customer price talks, not a formal notice, the company said. The stock locked limit-up at NT$207.5, up 9.78%, as the confirmation points to sustained pricing power across the CCL supply chain, with downstream PCB makers and electronics assemblers facing higher input costs.
Where the shortages bite
Nanya said it has raised prices on fiberglass cloth as it expands capacity and grows sales of low-thermal-expansion cloth grades. Electronic-grade fine yarn and specialty fiberglass with low dielectric constant and low thermal expansion are in tight supply, prompting price increases alongside output expansion. High-frequency copper foil is seeing strong demand with rising order share, and processing fees have been raised across specifications in a market where price and volume are rising together.
Copper-clad laminate supply is constrained by tight fiberglass cloth raw material, limiting rivals' access to inputs and lifting inquiry and order share toward Nanya. The company said it is accelerating the share of high-end products while adjusting prices on mid- and low-grade materials to reflect raw material costs, which it expects to lift August and third-quarter revenue.
AI servers drive a structural gap
The four major US cloud service providers continue to expand capital spending, pulling upstream electronic materials into structural shortage and price pressure, Nanya said. AI servers require larger chip areas, more layers, faster signal transmission and higher power consumption, driving demand for mid-to-high-grade materials. New capacity expansion is constrained by equipment suppliers' delivery capacity, so the supply-demand gap is unlikely to close in the near term.
The confirmation rippled through Taiwan's materials complex. Elite Material, a CCL maker, surged 8.34%, while the broader TAIEX closed down 210.47 points at 45,811.01 as TSMC fell 1.64% to NT$2,395. The price hikes contrast with a divergent memory sector, where SanDisk's upbeat guidance lifted Powerchip 4.67% and Winbond 3.67% while Nanya Technology and Phison declined.
What it means for investors
Nanya expects second-half profit to beat the first half, helped by strong electronic materials momentum and a strong performance from subsidiary Nanya Technology. For investors, the confirmation confirms pricing power across the CCL and materials chain — a tailwind for suppliers like Elite Material but a cost headwind for downstream PCB fabricators and electronics assemblers whose margins face compression. The structural supply-demand gap, tied to hyperscaler capex that shows no sign of slowing, suggests the pricing cycle has room to run into next year.
