关于股东股份减持计划的预披露公告
Major Shareholding Notification Classification · 95% confidence The document is a public announcement from Shanghai Kaixin Separation Technology Co., Ltd. regarding a pre-disclosure of a shareholder share reduction plan. It details the shareholders involved, the number of shares to be reduced, the method of reduction (centralized bidding), the timing, and the legal and regulatory compliance related to the share reduction. There is no financial report, earnings data, or management discussion of financial results. The document is focused on the shareholders' planned reduction of their holdings, which is a transaction involving shares owned by insiders but not a direct insider trade report. This fits the category of a Major Shareholding Notification or a shareholder reduction plan announcement. Given the detailed disclosure about shareholding changes and reduction plans, the best fitting category is Major Shareholding Notification (MRQ). The document length is 3431 characters, which is typical for such announcements. Therefore, the classification is MRQ with high confidence.
