SUNREX Business Summary

Sunrex Technology Corp. (2387.TW) is the world’s largest manufacturer of laptop keyboards, commanding a global market share of over 30%. The company operates an OEM/ODM business model, generating revenue through the high-volume production of computer peripherals and consumer electronic components. Its primary business segment is notebook keyboards, which account for approximately 90% of total revenue, supplemented by desktop keyboards, gaming peripherals, and high-value input modules such as Click Pads and capacitive stylus pens. Sunrex maintains a competitive edge through a vertically integrated manufacturing process that spans mold design, plastic injection, SMT, and final assembly. In response to shifting geopolitical dynamics, the company has aggressively expanded its production footprint beyond Mainland China, with its Vietnam facility commencing mass production in early 2026 to complement existing operations in Thailand and Taiwan. Within the global input device market, Sunrex competes directly with Chicony Electronics, Darfon Electronics, and Shenzhen Rapoo Technology, maintaining its leadership position through superior cost-efficiency and deep supply chain integration with major PC brands. The company is led by its founder and Chairman, Huo Lu Tsai (蔡火爐), a veteran entrepreneur who established the business in 1975 and pioneered precision plastic injection techniques through his earlier venture, Jing-Mold Enterprise. The current executive leadership team includes Vice Chairman Shu Ping Tsai Tseng (蔡曾淑萍) and President Yi Luo (羅逸), the latter of whom assumed the role of General Manager on January 1, 2026, to spearhead the company’s transition toward AI PC-compatible peripherals and automated production lines. Financial oversight is managed by CFO Ming Hung Wu (吳明鴻). The board of directors is characterized by long-term stability and significant insider ownership by the Tsai family, supported by institutional investors including JPMorgan Chase and specialized investment vehicles such as Jingyou and Jingli Investment Co., Ltd. This leadership structure has focused on maintaining high dividend yields and a robust balance sheet while navigating the cyclical nature of the global PC market.
