"The six policies on mergers and acquisitions" launched since its inception have quickly activated the M&A vitality of the A-share market, with numerous M&A restructuring cases coming one after another, among which there are not only high-quality M&A projects initiated by large companies obtaining green channels, but also some proposals released by listed companies that are not easy to determine whether they are high-quality acquisition targets. Against this background, the exchange promptly issued inquiries, further questioning the stability of the income, reasonable valuation, and reliability of performance commitments of the target companies in the proposed mergers and acquisitions, requiring relevant listed companies to disclose in detail and fully, in order for all parties to accurately determine the value and risk points involved. On November 12th, Suzhou Medicalsystem Technology received an inquiry letter from the SSE. According to incomplete statistics from reporters, since September, more than 10 listed companies have been planning cross-border mergers and acquisitions, including Shimao Energy, Dalian Bio-Chem, Jiangxi Lianchuang Opto-Electronic Science&Technology, and many other companies have received inquiries or regulatory letters from the SSE."
