GLOBALWAFERS Business Summary

GlobalWafers Co., Ltd. (6488.TWO) operates a vertically integrated business model centered on the manufacture and sale of high-purity silicon wafers, generating revenue through long-term supply agreements and spot market transactions with global semiconductor leaders like TSMC, Samsung, and Micron. The company’s primary business segments are categorized by wafer diameter and material, including advanced 300mm (12-inch) polished and epitaxial wafers, Silicon-on-Insulator (SOI) substrates, and high-growth compound semiconductors such as Silicon Carbide (SiC) and Gallium Nitride (GaN) for power electronics and AI applications. As of February 2026, the company is aggressively scaling its multi-billion dollar "GlobalWafers America" facility in Sherman, Texas, to capitalize on the U.S. CHIPS Act and the strategic shift toward localized semiconductor supply chains. Positioned as the world’s third-largest silicon wafer supplier with approximately 17% market share, GlobalWafers competes directly with Japan’s Shin-Etsu Chemical and SUMCO Corporation, Germany’s Siltronic AG, and South Korea’s SK Siltron, distinguishing itself through a highly diversified manufacturing footprint spanning nine countries. The leadership team is anchored by Chairperson and CEO Hsiu-Lan (Doris) Hsu, a globally recognized executive who orchestrated the company’s 2011 spinoff from Sino-American Silicon Products Inc. (SAS) and its subsequent M&A-led ascent. Hsu is supported by a veteran executive committee including President Mark England, Chief Financial Officer Ming Hui Chien, and Chief Technology Officer Wen-Ching Hsu, a team renowned for the successful integration of major acquisitions such as SunEdison Semiconductor (MEMC) and Topsil. The company maintains a strong corporate pedigree through its parent organization, SAS, which remains the majority shareholder with an approximate 46.6% stake. The board of directors, chaired by Hsu, includes influential industry figures like former SAS Chairman Ming-Kuang Lu and is backed by significant institutional investors such as Yuanta Securities and major global asset managers, reflecting the company's systemic importance to the global semiconductor ecosystem.
