Stock Price Soars 655%, Sichuan Brothers Build a 50 Billion Semiconductor IPO
Chengdu Ultra-pure Applied Materials Co., Ltd. ("Ultra-pure Materials"), a Sichuan-based supplier of core semiconductor equipment components, officially listed on the Shenzhen Stock Exchange on August 11. Its share price surged 654.66% to 498 yuan on its debut, giving the company a market capitalization exceeding 50.7 billion yuan.
Founded in 2005, the company is a national-level "little giant" specializing in special-coated components and precision optical devices for semiconductor equipment. It is one of the few domestic suppliers capable of providing core parts for 5nm and below process etching tools. According to a Frost & Sullivan report, it held the top market share (5.7%) among local Chinese suppliers of these coated components in 2024.
Financially, Ultra-pure Materials has shown rapid growth. Its revenue soared from 169 million yuan in 2023 to 496 million yuan in 2025, with net profit increasing from 65 million to 185 million yuan in the same period. Over 95% of its 2025 revenue came from sales of semiconductor equipment special-coated components.
The company has developed dozens of component products covering wafer fabrication, packaging, and silicon wafer manufacturing processes. Major customers include leading domestic semiconductor equipment manufacturers such as NAURA and AMEC, with its top five clients accounting for nearly 90% of revenue in 2025. Its shareholder structure features strategic investors including BYD, AMEC, and State Development & Investment Venture Capital.
Post-IPO, Chairman and CEO Chai Jie holds 31.42% of shares, while his brother and Chief Engineer Chai Lin holds 15.46%. The company plans to use raised capital for capacity expansion, R&D center construction, and supplementary working capital.
The global market for these high-precision components is dominated by US, European, and Japanese firms. However, driven by domestic equipment substitution policies and improving local technological capabilities, the localization rate in China is projected to rise significantly. Ultra-pure Materials' listing aims to strengthen its position in this expanding market.
