超纯股份IPO三股东“低价”突击入股，连续两年最大客户是关联方

Core Viewpoint - Chengdu Ultra-Pure Application Materials Co., Ltd. (referred to as "Ultra-Pure") is facing scrutiny regarding its IPO application, particularly concerning its low R&D investment and high reliance on a few major clients and suppliers [1][4][10]. Group 1: Financial Performance - Ultra-Pure's revenue and net profit have shown high growth rates, with a compound annual growth rate (CAGR) of 37.23% for revenue and 23.33% for net profit during the reporting period [11][12]. - The company's accounts receivable have increased at a faster rate than revenue, with a CAGR close to 50%, leading to a significant rise in bad debt provisions [12][13]. - As of June 30, 2025, Ultra-Pure's total assets and net assets were approximately 900 million and 730 million yuan, respectively, while the IPO fundraising amount is set at 1.125 billion yuan, which is about 1.54 times its latest net asset value [8][9]. Group 2: R&D Investment - Ultra-Pure's R&D investment has been consistently low, averaging around 5% of revenue, with absolute amounts only exceeding the 10 million yuan threshold required for the IPO in 2024 [4][5]. - The company has only 26 authorized patents, with just 12 being invention patents, indicating a lack of significant innovation [6]. Group 3: Client and Supplier Concentration - Ultra-Pure exhibits a high dependency on a few major clients, with the top five clients contributing over 80% of total revenue, and one major client being an affiliate [10][14]. - The company also relies heavily on a limited number of suppliers, with the top five suppliers accounting for over 60% of purchases, raising concerns about supply chain risks [15]. Group 4: Recent Shareholder Activity - Three new shareholders entered at a valuation of approximately 2.648 billion yuan just before the IPO application, raising questions about potential insider benefits as their investment has already appreciated by at least 70% [2][16][20]. - The last round of financing before the IPO did not show significant valuation growth compared to previous rounds, which is unusual and warrants further explanation from the company [20][21].
