第一大客户占比90%，注册地在开曼群岛，盛合晶微马年科创板IPO迎大考

Core Viewpoint - Shenghe Jingwei Semiconductor Co., Ltd. is on the verge of an IPO on the Sci-Tech Innovation Board, leveraging its advanced packaging technologies to achieve significant financial growth, but it faces structural risks including high customer concentration, sustainability of R&D investments, and investor protection challenges as a red-chip enterprise [2][3][4]. Customer Concentration Risks - The company has a high and increasing customer concentration, with the top five customers accounting for 72.83% of sales in 2022, rising to 90.87% by mid-2025 [4][16]. - The reliance on the largest customer has escalated from 40.56% in 2022 to 74.4% in mid-2025, indicating that over 70% of revenue and most profits are tied to a single client [4][16]. - This extreme dependency poses multiple risks, including operational stability, limited bargaining power, and financial health concerns due to low accounts receivable turnover [17][18]. R&D Investment and Sustainability Challenges - Despite rapid revenue growth, the company's R&D expenditure as a percentage of revenue has decreased from 15.72% in 2022 to 11.11% by mid-2025, raising concerns about the sustainability of its technological leadership [20]. - The number of R&D personnel has also declined, from 734 in 2023 to 663 in mid-2025, further questioning the company's core competitiveness [20][21]. - The company faces intense competition from global giants like TSMC and Intel, which invest significantly more in R&D, potentially jeopardizing Shenghe Jingwei's technological advantages [21]. Investor Protection Issues - As a red-chip enterprise registered in the Cayman Islands, Shenghe Jingwei faces inherent challenges in investor protection due to differences in legal frameworks compared to domestic companies [22][23]. - The complex corporate structure, involving multiple legal entities, complicates the realization of investor rights, such as dividends and participation in major decisions, increasing potential difficulties in exercising rights [23][24]. - The differences in shareholder rights and legal processes may hinder the ability of small investors to effectively monitor and protect their interests [22][23].
