Core Viewpoint - Xiamen Youxun Chip Co., Ltd. is facing scrutiny during its IPO process due to a prolonged control dispute and declining financial metrics, raising concerns about its operational sustainability and governance structure [1][3]. Financial Performance - The company's core product, the optical communication transceiver chip, accounts for over 80% of its revenue, projected to reach 411 million yuan in 2024 [3]. - The gross margin has decreased from 55.26% in 2022 to 43.48% in the first half of 2025, while the R&D expense ratio fell from 21.14% to 15.81%, significantly below the industry average [3]. Governance Issues - The company has experienced a 15-year control dispute, with a notable period from 2007 to 2016 where it had no actual controlling shareholder, leading to board deadlocks on critical issues [3][5]. - The control struggle originated from differing management philosophies, with founder Xu Ping initially holding 60% of the shares but gradually losing influence after a shift to a "chairman responsibility system" in 2009 [3][5]. Recent Developments - In 2022, the founder Ke Binglan and his son Ke Tenglong began consolidating control through various equity maneuvers, ending a nine-year governance deadlock [5]. - Currently, the Ke family controls 27.13% of the voting rights, but their stake is expected to dilute to around 20% post-IPO, raising concerns about the stability of control [5]. Regulatory Scrutiny - Regulatory inquiries focus on three main areas: the rationale behind the evolution of the controlling shareholder, the compliance of voting rights during the equity holding period, and the clarity and stability of the actual controller's authority [5]. - The company's dual distribution model, combining agency and buyout methods, has raised concerns about potential arbitrage opportunities among distributors, prompting the need for detailed explanations of pricing control mechanisms [5].
