Core Viewpoint - The announcement by Tianpu Co. regarding the acquisition by Zhonghao Xinying has led to significant stock price volatility, highlighting deficiencies in the A-share market's regulatory framework and signaling the need for improved disclosure and trading mechanisms [1][2]. Group 1: Issues Identified - The current disclosure system for major asset restructuring is inadequate, allowing for premature announcements based on preliminary agreements, which creates speculation and misinformation in the market [1][2]. - Insider trading regulations need to be strengthened, as there are discrepancies regarding the timing of trades by insiders in relation to the sensitive information [1][2]. - The stock suspension mechanism is overly rigid, failing to prevent speculative trading during periods of high uncertainty surrounding mergers and acquisitions [1][2]. Group 2: Recommendations for Improvement - Enhance the disclosure system for mergers and acquisitions by requiring that announcements only occur after obtaining necessary approvals and when major uncertainties are resolved, thereby reducing information asymmetry [2][3]. - Optimize the stock suspension design to prioritize investor protection and minimize market disruption during significant corporate events [2][3]. - Establish a clear linkage between major corporate actions and insider trading, ensuring that any investigations into misconduct halt the processing of related transactions [3]. - Implement measures to curb irrational speculation, including exploring the cancellation of the price limit system and encouraging media scrutiny of abnormal trading behaviors [3].

Core Points - Tianpu Co., Ltd. announced an abnormal stock price fluctuation, with a cumulative decline of 20% over three consecutive trading days on October 16, 17, and 20, 2025 [1][3] - The company confirmed that there is no undisclosed significant information apart from what has been publicly disclosed [1][3] - The acquirer, Zhonghao Xinying, has initiated the process for its initial public offering (IPO) and is currently in the stage of shareholding system reform, which is unrelated to the acquisition of the listed company [1][3]
