UNITED INTEGRATED SERVICES Business Summary

United Integrated Services Ltd. (UIS) operates an engineering, procurement, and construction (EPC) business model, generating revenue through high-complexity turnkey projects for the semiconductor and optoelectronics sectors. Its primary business segments include Engineering and Integration (cleanroom and piping systems), Maintenance and Design, and specialized environmental monitoring. As a critical Tier-1 contractor for global leaders like TSMC and Micron, UIS captures value from the semiconductor capital expenditure cycle, specifically in advanced 2nm fabrication and CoWoS packaging facilities. The company competes directly with Marketech International Corp (6196.TW), Acter Group (5536.TW), and Yankey Engineering (6691.TW), maintaining a dominant market share in Taiwan while aggressively expanding its footprint in the United States and Japan to support the global fab expansion of its primary foundry clients. The leadership team is headed by Chairman and CEO Hui Wen (Belle) Lee, who has served as a director since 1990 and has been instrumental in the company’s strategic pivot toward international fab integration. She is supported by President and Director Chih-Ming Lai, a key executive responsible for managing large-scale overseas projects, including the high-profile Fab 21 development in Arizona. The executive suite also includes Chief Engineer Hsiangching Tseng and Chief Business Officer Chun-Yuan Hsu, both of whom possess deep technical pedigree in high-tech facility planning and system coordination. Founded in 1982, the company maintains a stable governance structure with significant institutional backing from Liang Yi Investment and major domestic funds like Yuanta Securities, alongside inclusion in global indices such as the Vanguard FTSE Emerging Markets ETF.
