从营收到估值，沐曦上市有哪些隐忧？

Core Viewpoint - The article discusses the valuation and potential risks associated with the GPU company Muxi Integrated Circuit, which has a post-financing valuation of 21 billion yuan and is seeking to raise 3.904 billion yuan through its IPO. The focus is on whether the company's high valuation is justified or merely an illusion based on its financial performance and product dependency [2][28]. Group 1: Revenue Dependency and Risks - Muxi's revenue is heavily reliant on a single product, with over 97% of its income coming from one source, raising concerns about sustainability [3][7]. - The company reported a compound annual growth rate (CAGR) of 4074% from 2022 to 2024, with expectations for 2025 revenue to exceed 1 billion yuan, but this optimism is tempered by product structure issues [5][7]. - The revenue from Muxi's IP licensing business saw a dramatic decline of 95% from 2023 to 2024, indicating instability in its revenue streams [7][19]. Group 2: Customer Base and Related Transactions - Muxi's top five customers are also its shareholders, leading to potential conflicts of interest and questions about the sustainability of these relationships [10][15]. - The company’s major clients include Shanghai Yuanlu Jiajia Information Technology Co., which has a significant stake in Muxi, raising concerns about the nature of their transactions [11][15]. - The revenue contribution from major clients is substantial, with the top client contributing nearly 40% of the revenue in the first quarter of 2025, but the long-term stability of these relationships remains uncertain [16][18]. Group 3: Supply Chain and Product Development - Muxi is transitioning to a domestic supply chain for its new GPU products, which may introduce performance and cost challenges compared to its current suppliers [21][24]. - The upcoming C600 GPU is expected to have advanced features, but the acceptance of new products by customers is uncertain due to potential adaptation costs [22][26]. - The company aims to achieve breakeven by 2026, indicating a strategic shift in operations and product offerings to enhance competitiveness in the market [27][28].
