Core Viewpoint - The recent change in the legal representative of Zhuhai Zero Boundary Integrated Circuit Company, with Dong Mingzhu stepping down and Li Bin taking over, raises questions about Dong's future plans and potential retirement [1]. Company Overview - Zhuhai Zero Boundary Integrated Circuit Company is a core subsidiary of Gree Electric Appliances, focusing on semiconductor research and manufacturing, particularly in air conditioning control chips, power semiconductors (such as IGBT and SiC), and AIoT chips, serving sectors like home appliances, industrial control, and new energy vehicles [4][5]. - As of 2024, the company has shipped over 200 million chips with a defect rate as low as 0.00001, meeting international standards [5]. Investment and Strategy - Gree has invested over 50 billion in chip manufacturing since 2018, despite skepticism regarding the feasibility of entering the semiconductor industry [7]. - Dong Mingzhu believes that the investment in chip manufacturing is essential for both national needs and the company's growth, viewing it as a responsibility of Chinese manufacturing [7][9]. - The long-term goal is to break the cycle of dependency on imported chips, with a target of achieving over 30% self-sufficiency in home appliance chips, which would allow Gree to gain pricing power in the industry [11][12]. Financial Implications - Gree's annual sales of 65 million air conditioners, along with a chip gross margin of 45%, indicate significant cost savings and potential for export if the company achieves chip self-sufficiency [11].
