未名医药核心子公司被停产，所产干扰素已遭多地停购

Core Viewpoint - Unimed Pharmaceutical faces significant operational challenges due to regulatory issues with its subsidiary Tianjin Weiming Biopharmaceutical Co., which has been ordered to suspend production and sales due to non-compliance with drug production quality management standards [1][2]. Group 1: Regulatory Issues - Tianjin Weiming was found to have production practices that do not meet the 2010 revised Drug Production Quality Management Standards, leading to a suspension of production and sales [1]. - The company must complete rectification and inspection before resuming production, which could take up to three months [1]. - If production is not restored within three months, Unimed may face additional risk warnings and could be subject to special treatment (ST) [1]. Group 2: Financial Impact - Following the announcement, Unimed's stock price dropped by 9.95%, closing at 7.42 yuan per share, with a market capitalization of 4.895 billion yuan [1]. - In 2024, Tianjin Weiming generated revenue of 217 million yuan, accounting for 60.09% of Unimed's total revenue, but reported a net loss of 14.0037 million yuan [1][2]. - The recall of a specific batch of interferon α2b spray due to non-compliance resulted in a revenue reduction of 23.1672 million yuan for Unimed [2]. Group 3: Historical Performance - Unimed has experienced fluctuating performance, with five out of the last seven years resulting in losses, particularly since 2018 [3]. - The company has faced multiple operational setbacks, including the suspension of its subsidiary Weiming Tianyuan due to environmental regulations and significant revenue declines in its core products [3][4]. - The ongoing control disputes over Beijing Kexing have further complicated Unimed's operational stability and financial performance [4]. Group 4: Current Business Structure - Unimed's operations are heavily reliant on three key subsidiaries: Tianjin Weiming, Xiamen Weiming, and Beijing Kexing [5]. - The revenue from the previously significant product, nerve growth factor, has decreased to 139 million yuan, representing only 38.59% of total revenue in 2024 [5]. - With Tianjin Weiming's current regulatory issues, Unimed faces potential operational crises as it relies on this subsidiary for a substantial portion of its income [5].
