What YANKEY ENGINEERING CO LTD does

Yankey Engineering Co., Ltd. (洋基工程股份有限公司, TWSE: 6691) is a Taiwan-headquartered EPC turnkey engineering contractor specializing in mechanical, electrical, plumbing (MEP) and cleanroom systems for high-tech industrial facilities. Founded in 1980 and listed on the Taiwan Stock Exchange in January 2022, the company delivers integrated services spanning cleanroom temperature/humidity control, high/low voltage power transmission, commercial HVAC, fire protection, process piping, plumbing/drainage, process exhaust, monitoring/low-voltage systems, and green building/LEED certification. Its technology stack centers on 3D BIM-based coordination for multi-discipline value engineering and the internally-developed York.AI agent platform, which has reportedly reduced power pipe rack design time by ~83% in selected workflows.

The company employs 976 professional personnel across Taiwan, mainland China (Suzhou and Dongguan), Vietnam, and Thailand, with regional offices in Taipei (HQ in Linkou), Hsinchu, Taichung, Tainan, and the newly opened Kaohsiung branch. Revenue is generated through project-based, multi-year EPC contracts negotiated bilaterally with enterprise customers—predominantly semiconductor fabs, IC packaging/testing facilities, PCB/BGA plants, and large commercial developments. Yankey's customer base includes TSMC (Fab 18, AP6A, F18P1, Fab 6 Phase 2, 15P5, BP-05, 12P8, AP6B, 14p7, 16P1), Micron (Tainan fab, Falcon Metallization), ASML (Linkou Park), Powerchip, Xin Tec, Unimicron, Kinsus, Unitech, Tong Hsing, Innolux, ASUS, TPK, and ASUSTeK. The business model is direct enterprise field sales with no channel intermediaries, supported by certifications including ISO 9001, ISO 14001, ISO 27001:2022, ISO 45001, and country-specific contracting licenses (BCA Singapore, CIDB G7 Malaysia, Vietnam Grade 3, China Class 1).
