WHOLETECH Business Summary

Wholetech System Hitech Limited (3402.TWO) operates as a premier total solutions provider for high-tech facility engineering, primarily serving the semiconductor, optoelectronics, and pharmaceutical sectors. The company generates revenue through a project-based model encompassing the design, construction, and maintenance of ultra-high purity (UHP) gas piping systems, cleanroom environments, and mechanical, electrical, and process (MEP) integration. Its business is structured into six core divisions, including Gas Engineering, Specialty Gas Supply Systems, and System Software Development, supplemented by the manufacture and sale of proprietary equipment such as gas cabinets and exhaust gas handlers. Within the competitive landscape of Taiwan’s semiconductor auxiliary services, Wholetech competes directly with Marketech International Corp (6196), Acter Co., Ltd. (5536), and United Integrated Services (2404). It maintains a specialized market position by offering high-agility, turnkey engineering for advanced node fabrication facilities, often acting as a critical Tier-1 or Tier-2 partner to global foundry leaders. The company is led by Chairman Wen-Hwa Lin, who has overseen Wholetech’s evolution from its 1990 founding into a publicly traded entity on the TPEx. Operational leadership is spearheaded by President and Director Ching Chuan (Sting) Hsieh, who previously served as General Manager and brings extensive technical expertise in electromechanical system integration and high-purity gas delivery. The leadership team is characterized by deep roots in the Hsinchu Science Park industrial cluster, emphasizing long-term technical reliability and safety compliance (ISO 9001, SEMI S2). A notable strategic anchor for the company is United Integrated Services Co., Ltd. (UIS), which remains a top institutional shareholder with a stake exceeding 13% as of early 2026. This relationship, alongside holdings from institutional investors like Yihua Technology, provides Wholetech with significant financial stability and collaborative project opportunities within the broader global semiconductor supply chain.
