Core Viewpoint - The lawsuit involving Suzhou Nawei Technology Co., Ltd. is currently in the appeal stage, with both the plaintiff and defendants contesting the first-instance judgment. The company is a third party in the case and does not bear any liability, ensuring that its operations and profits remain unaffected by the litigation [2][11]. Summary by Sections Lawsuit Background - On December 5, 2022, the company received a civil complaint from Han Han, who is seeking to confirm a claim of 51,556,500 yuan for a share of 5,698,350 yuan held by Suzhou Nabai [3]. - The lawsuit has evolved, with Han Han modifying his claims on August 31, 2023, to seek 38,273,600 yuan for a share of 4,230,240 yuan and additional compensation for 2,656,580 shares [4]. - By May 31, 2024, Han Han introduced an alternative claim for 302,596,775.52 yuan in damages, along with interest calculations based on LPR standards [5]. Court Decisions and Appeals - On August 12, 2024, the court ruled that Suzhou Nabai must pay Han Han 18,994,500 yuan, while other claims were dismissed [6]. - In September 2024, both parties filed appeals against the judgment, with Suzhou Nabai seeking to overturn the ruling and Han Han requesting full support for his claims [6][8]. Recent Developments - To mitigate the impact of the lawsuit on the company's stock incentive plans, Suzhou Nabai and its chairman, Dr. Jiang Biwang, submitted a request to the Jiangsu Provincial High Court to replace frozen assets with equivalent shares [9]. - The court has since ruled to freeze 5,112,900 shares held by Dr. Jiang while lifting the asset preservation measures on Suzhou Nabai's partnership interests [9][10]. Impact on Company Operations - The company maintains that the lawsuit will not affect its operational stability or governance, as it is involved as a third party and is not liable for any claims [11]. - The freezing of 1.27% of the company's shares held by Dr. Jiang will not alter the control structure of the company, ensuring that its management remains stable [11].
