YTD as of 2026-07-09 · source: Yahoo Finance
GlobalWafers's thesis is its position as an oligopoly materials supplier at the very top of the semiconductor chain. Roughly No.3 in 300mm silicon wafers (~15%, after Shin-Etsu and SUMCO), it counts nearly every fab as a customer — TSMC, UMC, Samsung, SK hynix, Micron, Intel. Wafers are the starting substrate of every chip, so fab utilization and expansion are demand, and a hard-to-enter oligopoly defends pricing. FY2025 net profit was NT$7.3bn (EPS NT$15.29) with H1 revenue of NT$31.6bn (+3.9%) — solid, though earnings stayed below the prior peak as wafer demand has not fully recovered. The growth axis is US localization: in May 2025 it opened its $3.5B first advanced 300mm US fab (GWA) in Sherman, Texas, with +$4B of further expansion (1.2M wafers/month at full capacity) and $400M of CHIPS funding, turning geopolitical/tariff risk into opportunity. Its Siltronic bid was blocked by the German government, and it broadens into compound wafers such as SiC. Re-rating triggers are the fab-capacity cycle, long-term-agreement (LTA) pricing (new-contract hikes), and utilization of new capacity such as Sherman.
