Securities Hit Attention Trading Disclosure Threshold
The company disclosed that its listed securities have triggered the Taiwan exchange's 'attention trading information' threshold, a market-surveillance flag typically tied to abnormal price volatility or trading volume. This is a procedural disclosure intended to alert investors to monitor the stock more carefully and does not by itself indicate a fundamental corporate event. Full body available on MOPS.

Notes

GlobalWafers is the world's third-largest silicon wafer supplier by revenue, headquartered in Taiwan. After its 2022 attempt to acquire Siltronic was blocked by Germany, it pivoted to a global greenfield expansion plan including a 300mm fab in Sherman, Texas backed by US CHIPS Act funding. Note: KRX ticker 6488 appears incorrect — GlobalWafers trades on the Taiwan TPEx under ticker 6488, not KRX; it is a Taiwanese, not Korean, company.

May 2026 Revenue: NT$4.84B, -3.3% YoY

GlobalWafers reported May 2026 revenue of NT$4.84B, down 3.3% YoY but up 2.0% MoM from NT$4.75B in April. YTD revenue stands at NT$23.57B, down 8.9% versus the same period last year, suggesting the silicon wafer cycle remains soft despite sequential improvement — AI/HBM demand has yet to fully offset weakness in mature-node and memory wafer segments.

Q1 2026 Earnings: Revenue NT$14.0B, EPS NT$3.97

GlobalWafers (6488) reported Q1 2026 revenue of NT$14.0B with operating income of NT$1.48B and net income after tax of NT$1.90B, translating to basic EPS of NT$3.97. Non-operating income contributed a sizable NT$871M, lifting bottom-line results above operating profitability alone. Results appear solid for a silicon wafer supplier amid an uneven semiconductor capex cycle, though not a dramatic outlier versus sector norms.

Apr 2026 Revenue: NT$4.75B, -10.1% YoY

GlobalWafers reported April 2026 revenue of NT$4.75B, down 10.1% YoY and 12.8% MoM from NT$5.45B in March. The sequential decline signals continued softness in silicon wafer demand, with AI/HBM-driven leading-edge logic strength insufficient to offset weakness in mature-node and memory wafer end-markets.
